Description
Technical Field
The utility model relates to a refuse handling installation, especially a kitchen garbage and domestic waste coprocessing facilities.
Background
The existing kitchen waste treatment project (kitchen project for short) and the household waste incineration project (raw incineration project for short) are separately constructed and operated as two projects.
The kitchen project is independently constructed and operated, and an oil-gas dual-purpose steam boiler is required to be constructed to provide steam for a system, provide process water for a water supply system, provide softened water for a boiler for a softened water system and provide blowing or compressed air for instrument control through air compression according to energy requirements; from the perspective of three-waste treatment, a sewage treatment station needs to be built to ensure that the sewage is discharged after treatment and an odor treatment system ensures that the purified gas is discharged after treatment, and a solid impurity receiving protocol needs to be coordinated or signed with a refuse landfill or an incineration plant. In the project debugging and starting stage, diesel oil is needed to be purchased as the fuel of a steam boiler to supply heat for a pretreatment system, and sludge is purchased as the inoculation sludge of an anaerobic system. In the project operation stage, due to the fact that the kitchen waste is extremely easy to acidify, the operation stability of an anaerobic system needs to be closely concerned.
Besides a core processing system, a plurality of matching systems and facilities are required to be built in the kitchen project, so that the floor area of the project is large, the investment is high, and the operation, maintenance and management costs of the project are increased.
In the kitchen project debugging stage, heat for maintaining stable temperature through anaerobic fermentation needs to be provided by steam, and although the project is matched with an oil-gas dual-purpose steam boiler, the anaerobic stage is not normally operated temporarily, the methane yield is very small, so that the steam boiler needs to purchase diesel as fuel, and safety risk exists when a large amount of diesel enters a factory.
The kitchen project debugging stage needs to purchase and inoculate sludge, the purchased sludge needs to enter a factory in batches uniformly in about half a month, the purchase and transportation of the sludge not only needs cost, but also has the problem that the debugging stage is discontinuous due to the unstable sludge amount, so that the risk of overlong project starting period is caused.
In the operation stage of the kitchen project, tap water or other industrial water sources are needed as process water; softened water required by a steam boiler or a waste heat boiler of a methane generator set needs to be prepared and provided by building a softened water system; an air compression system is provided to provide compressed air for purging or instrumentation of the system.
In the operation stage of the kitchen project, solid impurities generated by process operation need to be transported and buried or incinerated, land resources are occupied, and harmlessness, recycling and reduction are not thorough.
In the operation stage of the kitchen project, as the fermentation raw material is single kitchen waste, the kitchen waste has the characteristics of being extremely easy to acidify, lacking in trace elements and the like, anaerobic fermentation parameters are difficult to control, the operation stability is poor, and the methane yield is unstable. In the operation stage, anaerobic fermentation parameters need to be closely monitored and alkalinity and trace elements need to be supplemented timely.
The incineration project is independently constructed and operated, and the biogas generated by the anaerobic system of the matched leachate treatment station is incinerated by an incinerator or burnt by a torch. The problem of low utilization rate of methane heat value exists in power generation by burning methane in the incinerator; if the marsh gas is not burnt in the furnace, a marsh gas torch is used for burning, and the resource is wasted. However, as the yield of the biogas is not very large, the incineration project is not generally used for independently constructing a biogas utilization system.
Therefore, there is a need to provide a kitchen waste and household waste co-processing facility to at least partially solve the above problems.
