At present, in the field of waste incineration, domestic waste disposal urban and rural integration model sought after. However, disposal of fly ash has become the major shortfall in the waste incineration industry, with higher disposal costs and the difficulty and shadow of regulation. The promotion of new technologies is difficult to break the inherent philosophy, enterprises are highly sensitive to market demand, focusing on technology independent research and development, but the market needs to accept the process.

Disposal of fly ash into a major short-term waste incineration technology is still time to promote new technologies

"The garbage incineration industry is in the peak period, the market capacity is also very transparent and the competition pattern is slowly solidifying." Liu Chang, deputy chief engineer of the Environmental Health Engineering Research Center of Ministry of Housing and Urban-Rural Development recently held a speech at the 7th China Waste Incineration Power Generation Development Forum cum Wuxi Solid waste treatment technology exchange meeting said.

It is understood that at present, Hanlan Environment, Shanghai Environment, Chongqing Sanfeng, Everbright International, Hangzhou Jinjiang eight companies, accounting for more than 40% of municipal waste incineration power generation market. Experience the ups and downs in recent years, what are the market opportunities for waste incineration industry can be tapped, is still facing any problems?

Domestic garbage disposal urban-rural integration model sought after

Economically developed areas should promote the integration of urban and rural areas, underdeveloped economy, remote areas suitable for the implementation of limited collection, centralized treatment

"While the concentration of brands in the municipal waste incineration power generation industry continues to increase, the rural market has great potential." Liu Chang believes.

He enumerated two sets of data: From the point of view of trash removal, a total of 730 million people in the country's suburban counties still have not covered the rubbish, while the rural areas in the suburbs make up about 500 million. In terms of management input, in 2013, the city invested 44.2 billion yuan and the rural investment was 32.5 billion yuan. In 2015, the city invested 38.6 billion yuan and the rural sector invested 37.2 billion yuan.

Through data comparison, rural domestic waste disposal needs, investment is also increasing. As a result, there are more opportunities for companies to participate in the technology for rural domestic waste disposal. Among them, the conditions of rural areas can be integrated urban and rural areas to deal with the disposal of domestic waste.

It is understood that in the exploration of urban-rural integration mode, many places in our country have been explored and specific policy guidelines have been issued.

On August 11, 2016, Henan Province proposed that by 2020, the provincial municipality will complete the planning and construction of municipal solid waste incineration facilities covering a radius of 60 kilometers to form a new garbage collection and disposal area for "urban transhipment and municipal treatment" mode.

January 20 this year, Shandong Province also proposed that in principle the new treatment facilities should choose incineration (power generation) processing technology, the existing life garbage disposal facilities expected life of less than 5 years of cities and counties, to immediately start the household waste incineration facilities Project construction.

Chuzhou in Anhui Province, the urban areas and neighboring Lai County, Quanjiao County has touched the river first, through the construction of domestic waste incineration power plants, to achieve the integration of rural garbage disposal.

Xu Haiyun, chief engineer of China Academy of Urban Construction Co., Ltd. said that for the economically developed areas such as southern Jiangsu, urban and rural areas should be promoted, and for underdeveloped areas, remote areas should be suitable for limited collection and centralized processing.

Disposal of fly ash into the main shortfall in the incineration industry

Higher domestic disposal costs, regulatory difficulties and blind spots

In 2016, Yunnan and Heilongjiang provinces carried out special inspections of waste incineration power plants in their jurisdictions and found that the overwhelming majority of enterprises had environmental violations and the illegal handling of fly ash was the most common.

Xu Haiyun pointed out that although the fly ash has been included in the latest list of hazardous waste exemption list, but also in accordance with hazardous waste management. Judging from the current actual situation, it is a messy account. "The problem of fly ash has become the main shortcomings restricting the development of China's waste incineration."

Zhao Youcai, a professor at Tongji University School of Environmental Science and Engineering, disclosed that at present many incineration plants mix fly ash into slag together because slag is considered as solid waste and has low disposal costs. However, the consequence is that the original slag can be bricks because the incorporation of fly ash lead to excessive salt content, only into the landfill.

"Upon request, the fly ash into the landfill need to be cured and stabilized, but in actual operation landfill have not done.Add cement, chelating agent curing a stable ten days, need to add a lot of additional costs." To be blunt, fly ash landfill in the management there are many problems, any high moisture content, un-cured fly ash dumping, leading to dusty, leachate outflow.

Xu Haiyun also said that the current domestic disposal costs are high, but the supervision of the difficulty and blind spots, resulting in different methods of disposal of fly ash companies. For example, he used Beijing cement co-processing cement kiln, 1 ton of fly ash disposal costs about 1500 yuan, according to 1 ton of garbage generated 2.5% of fly ash, tons of garbage fly ash disposal nearly 40 yuan; chelating agent plus cement solidified landfill The cost of 600 yuan to 900 yuan price range; and almost no cost of comprehensive utilization.

New technology is difficult to break the inherent concept of promotion

Enterprises are highly sensitive to market demand, focusing on technology independent research and development, but the market needs to accept the process

For the problem of fly ash, many domestic enterprises and teams began to develop their own technology. For example, Zhao You Cai team developed a high static pressure technology.

He said that the original intention of technology research and development is to save the storage capacity of fly ash landfill by high-pressure hydraulic system to make fly ash to form a higher proportion (relative density) of the block, the volume can be reduced by 50% to 80%, can be extended Landfill more than 1 times the service life. At the same time, the resulting advantage is a reduction in leaching toxicity, which results in a 80% reduction in chelator usage, which, in combination, can reduce fly ash operating costs by 200 yuan / tonne.

However, because landfills are government-run, incineration plants are not very interested in this technology, and some local VCs showed interest because of debt pressure because of cost considerations. "Zhao Yusai said that the difficulty of new technology promotion Great.

Beijing Huake Instrument Co., Ltd. Deputy General Manager Yu Feng also have deep feelings, "private enterprises on the market is very high sensitivity, generally where there is demand on the focus, and constantly develop new products.But promotion, it is difficult to break the inherent customer Experience and philosophy. "

According to him, the company's latest independent research and development of chemistry

6. Central Fume Extraction System

1) Cantilever type fume extraction system

Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the suction hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

2) Hood suction type fume extraction system

Cantilever dust removal can be used for manual welding conditions where the work stations are evenly distributed and the span is small. The smoke and dust generated by each welding station can be effectively absorbed at the dust generation point, and will not pollute other parts of the workshop. The skeleton of the suction arm is similar to a human arm and can hover in a space within a certain length. The outer layer of the suction arm is a temperature-resistant hose, which not only prevents the hose from being burned by sparks, but also ensures the flexibility of the movement of the suction arm. A unique rotating structure is designed on the position of the suction hood to ensure that the suction hood can be aligned with the welding position in any orientation, so that the suction arm can effectively capture the smoke and dust generated during the welding process. The advantage of the suction arm capture is that it can be close to the place where the smoke is generated, and the collection effect is better.

3) Room tupe fume extraction system

Room-type dust removal is suitable for the purification of fumes and smoke generated during the production of automated equipment, such as welding robots, welding machines, grinding, grinding and polishing of metal and plastic parts, drilling, thermal processing, cutting and crushing, stone processing, powder packaging, solid particles and various dusts and fumes produced by mixing and processing.

For working conditions such as robot automatic welding, circular seam and longitudinal seam welding, the smoke and dust purifier is installed with the robot workstation, so that the workstation has its own dust removal function. The fume and smoke are effectively collected through equipment components such as pipes and dust hoods. The room-type design prevents the volatilization and diffusion of smoke to keep the air in the workshop clean.

The working conditions with moderate welding workpieces and large amounts of dust and smoke are suitable for room-type treatment solutions. The room type centralized dust dedusting solution is divided into side suction and top suction method dust collecting ways. The appropriate solution can be designed according to the site conditions and treatment goals.

4) Blow suction type fume extraction system

Blow-suction type dust removal solution is a ventilation air flow composed of blown air and inhaled air flow. Therefore, it is a dust removal method that can effectively control the spread of pollution sources. This dust removal method is installing exhaust inlets on two-span center column or single-span side column (wall) and air outlets on the opposite wall column to form a circulating air flow to drive the smoke and dust into the purification machine, consequently performing overall dust removal and purification in the workshop. This system occupies a small area and has obvious purification effect, which is suitable for the purification of smoke and smoke in more complex production workshops.
