Description
Technical Field
The invention relates to the technical field of garbage treatment, in particular to a garbage pool bottom heating device.
Background
The freshly collected household garbage generally contains a large amount of water and has a very low calorific value. The garbage is directly sent into a boiler for burning, so that a fire extinguishing effect can be generated, combustion is unstable, the burning efficiency of the boiler is reduced, and the risks of fire extinguishment and furnace shutdown of the boiler are further caused. Therefore, the low-temperature fermentation process is carried out for a certain time before the garbage is put into the furnace for burning, and part of water in the garbage is removed, so that the proportion of combustible components in the garbage is increased, and the heat value is improved.
In winter in the north, the collected household garbage has the phenomenon of partial freezing, and can not be directly connected into a furnace for burning. If the low-temperature fermentation process in the south is adopted, the fermentation time must be prolonged, so that the design capacity of the garbage pool is increased, and the civil engineering investment is increased by 50-100%. Therefore, the thawing and heat preservation method of the fresh garbage in the garbage pool must be considered in the design and construction period of the garbage incineration power plant in the north.
The current northern waste incineration power plant mainly adopts a heat preservation and thawing method of waste heat, hot water and spraying.
Spraying method: and spraying the heated landfill leachate back into a garbage pool for thawing treatment. The method can increase the water content of the fresh garbage, prolong the garbage fermentation time, increase the load of the garbage pool wall and improve the investment of the garbage pool and the auxiliary building.
Waste heat method: the sewage with continuous sewage discharge and periodic sewage discharge is used as a heat source, heat is dissipated in the garbage pool, air above the garbage pool is heated, and the sewage is directly sprayed into the garbage pool. The former method has the advantages that the heat source is not in direct contact with garbage, and the heat is limited; the latter is similar to spraying, and can increase the water content of fresh garbage.
Hot water method: and (3) laying a hot water pipeline (geothermal) at the bottom of the garbage pool according to a method of low-temperature hot water radiation heating in the building room. The method has limited heat, and the upper limit of water temperature is 60 ℃ due to the influence of the pipe, only limited garbage heat preservation effect can be provided, and garbage thawing capability is basically avoided. When the operation time of the garbage pool is long, the deposited sludge at the bottom of the garbage pool is hardened, the heat transfer coefficient of hot water is reduced, and the hot water has no heating effect basically. Meanwhile, as the pipeline is buried below the concrete layer at the bottom of the garbage pool, the system is a disposable product, so that leakage points cannot be found, and maintenance cannot be performed.
