Description

Domestic waste cracking treatment device and process

The present invention relates to the treatment technology of urban domestic garbage, in particular to a cracking treatment device for automatically dewatering waste after being classified and crushed, that is, a specific device and process for turning it into a treasure. Background technique

Disposal of garbage is a major and urgent issue facing the world. Pulling garbage directly to a planned place far away from towns for landfilling is a commonly adopted method, but its harm still exists. The first is that the piled garbage directly taints the atmosphere due to its foul odor and the emission of biogas; the second is that the sewage produced directly pollutes the water resources in the landfill area under the impact of rainwater infiltration when it rains; the third is the occupation of land Large area, solid pollution sources still exist, forming long-term pollution.

In order to solve the problem of garbage pollution, in recent years, many feasible solutions have been proposed in garbage disposal at home and abroad, such as incineration treatment, biogas production, fuel oil production, manufacturing of building materials, and microbial treatment. Among them, there are three successful schemes: one is to set up a waste incineration plant, that is, to incinerate all the waste, use the heat generated by the incineration to generate electricity, and landfill the residue and ashes after the incineration; It is used as the raw material for biogas, and uses biogas to generate electricity. Third, the waste is separated and processed under cold conditions, which can be used to recover useful things and be used as fertilizer. These three options are extremely positive in a sense, but there are still many shortcomings. For example, all incineration will turn the recyclable "treasures" into ashes, and the smoke, waste water, noise, stench, residues and so on during the incineration will cause re-contamination: especially the dioxin produced will seriously affect people As a result, the incineration of waste gas is increased on the basis of incineration. In short, the cost of incineration waste is relatively high. From the analysis of the problem of using all waste as raw materials for biogas, the waste contains less than 15% of raw materials that can be used to produce biogas. Therefore, using all waste as raw materials for biogas not only has a large pool area, but also has a lot of residues, which is not suitable. Treat as fertilizer. The implementation of a scheme for separating and treating garbage under cold conditions is proactive and feasible from the analysis of pollution prevention such as odor, but the process is complicated, the labor and land are too large, and the automatic production of δ capital is larger. At present, there is only equipment for separating and treating garbage, and there is no related equipment for 100% separation and treatment.

According to the search of relevant data of Chinese patents and the like, it is indicated that, in addition to the "Industrial Waste Cracking Treatment Device and Process" applied by the inventor on November 29, 2001, the application number is 01139744. 6, but the waste cracking treatment and Reports of related devices and processes that can recover their useful gases and solids after treatment. Summary of the invention In order to overcome the shortcomings of the existing waste treatment, the present invention further provides a cracking treatment which is automatically dehydrated after the waste is classified and crushed on the basis of the original invention 01139744. 6, which can realize gas recycling and solids as activated carbon and building materials after treatment.
