Use of dry Jujun grass in refuse incineration process

Abstract

The invention discloses an application of dry giant bacteria grass in incineration treatment of garbage. The application is as follows: each portion of weight part of coal or fuel is substituted by 1.5 portions to 2 portions of weight part of dry giant bacteria grass to support to incinerate the garbage for a garbage incineration furnace with the daily amount of garbage treatment more than 300 tons; and adding portion of the dry giant bacteria grass is that each portion of weight part of garbage is added with two portions of weight parts of the dry giant bacteria grass to be mixed and burned together for the garbage incineration furnace with the daily amount of garbage treatment lower than 300 tons.

Description

technical field [0001] The invention relates to the application of dried giant juncao in waste incineration treatment. Background technique [0002] Some places in my country stipulate that if the amount of urban waste is more than 300 tons / day, the waste will be incinerated to generate electricity, and if the amount of urban waste is less than 300 tons / day, the waste will be used in sanitary landfill. The current dilemma of waste incineration: For the incineration of more than 300 tons of waste per day, because domestic waste in our country is not collected in advance by classification, but mixed collection, it is not easy to incinerate, and auxiliary fuel - coal or fuel oil must be added to ensure that the incinerator can Only by keeping the furnace temperature above 850°C can the carcinogenic dioxins be effectively decomposed; however, the added combustion aids are non-renewable fossil fuels on the one hand, and on the other hand, they can produce harmful gases such as ca...

The current dilemma of waste incineration: For the incineration of more than 300 tons of waste per day, because domestic waste in our country is not collected in advance by classification, but mixed collection, it is not easy to incinerate, and auxiliary fuel - coal or fuel oil must be added to ensure that the incinerator can Only by keeping the furnace temperature above 850°C can the carcinogenic dioxins be effectively decomposed; however, the added combustion aids are non-renewable fossil fuels on the one hand, and on the other hand, they can produce harmful gases such as carbon dioxide and sulfide , thus causing secondary pollution to the environment; in particular, the generated landfill leachate must be specially treated. If it is treated by spraying back to the incinerator and producing compost, it will reduce the furnace temperature and cause a large amount of dioxins to be produced , and the produced compost cannot be sold because of its low fertilizer content, all of which lead to increased investment and operating costs! For the waste treatment with the amount of waste less than 300 tons / day, due to the small amount of waste, the incineration power generation is also small, and the income is also small, and the incineration power generation process requires a large investment. Therefore, if the incineration power generation method is also used, it will inevitably cause It is difficult to recover the investment, so we have to reluctantly adopt the sanitary landfill method, but landfill waste occupies a large area and wastes land resources
