Description
Technical Field
The utility model relates to the technical field of solid waste treatment, in particular to a device for co-producing household garbage incineration and waste tire pyrolysis.
Background
With the rapid development of national economy and the increasing improvement of the living standard of people, the domestic garbage is increased gradually, and the dilemma of 'garbage enclosing city' is highlighted. The reasonable treatment of the garbage plays an increasingly important role in practicing a green development idea and promoting the ecological civilization construction process. At present, the treatment mode of the household garbage has three types: direct incineration, sanitary landfills and composting. Compared with landfill which is easy to cause secondary pollution and waste compost which is difficult to sell, the household garbage incineration power generation technology is gradually a mainstream way for treating household garbage in China as a method for utilizing solid waste resources. The heat in the purified and dedusted flue gas at the tail part of the waste heat boiler of the waste incineration power station is recycled, and the reduction of the smoke discharge loss has very important significance for improving the boiler efficiency and the power generation economy of the whole plant.
In recent years, the automobile yield in China is rapidly increased, so that the development of the tire industry is driven, and a large amount of waste tires are brought. From 2012 onwards, the annual global tire production has broken through 2000 ten thousand tons, with the tire production in our country being 1000 ten thousand tons. The main methods for recycling waste tires are divided into physical treatment and chemical treatment. The physical treatment mainly comprises retreaded tires, reclaimed rubber and rubber powder, and most of the physical treatment technologies have high energy consumption and low profit. Therefore, most rubber powder enterprises are in a loss state at present. The chemical treatment is mainly a waste tyre thermochemical treatment technology, comprising pyrolysis, incineration and gasification technologies. However, incineration and gasification both cause different levels of environmental damage. The pyrolysis technology has low energy consumption, and products of the pyrolysis oil, the carbonaceous materials and the like have great utilization value. Therefore, the pyrolysis technology becomes an important method for solving the problem of recycling the waste tires.
The main products of the pyrolysis of the waste tires are pyrolysis gas, pyrolysis oil and pyrolysis carbon black. The pyrolysis gas is non-pour-point depression waste gas formed in the process of pyrolysis and condensation of the waste tire, and mainly comprises CO2、CO、H2、CH4、C2H6、C3H8、C4H6And the amount of the pyrolysis gas is about 30 to 53 percent of the total amount of the pyrolysis gas. The calorific value of the pyrolysis gas is similar to that of natural gas, so that the pyrolysis gas can be directly used as fuel gas. The high-calorific-value pyrolysis gas is used for heat generation and power generation, has considerable economic benefit, can make up the current situation of coal shortage as a high-calorific-value energy source, and has good development prospect. Therefore, the recycled flue gas enters the waste heat boiler, the circulating water absorbing the waste heat of the discharged flue gas is used as the working medium of the steam cycle power generation system, and the feed water is evaporated in the waste heat boiler and then enters the steam turbine to do work to drive the generator to generate power. Pyrolysis oil and pyrolytic carbon in the pyrolysis product can be stored and utilized, and the whole system realizes high-efficiency synergy of energy conservation, environmental protection and economy.
