Problems solved by technology

During the treatment and disposal of domestic waste, such as landfill, composting, and incineration, a large amount of acid waste gas such as carbon dioxide and hydrogen sulfide will be produced. In addition, carbon dioxide is also controlled worldwide as a greenhouse gas; hydrogen sulfide is also a malodorous gas. Proper treatment and disposal, the volume percentage of carbon dioxide in the domestic waste landfill process is 30-45%, and the amount of carbon dioxide produced in the high temperature period of composting is as high as 80%. In the process of domestic waste treatment and disposal, these acid gases are often not used as resources Directly discharged into the atmosphere, causing a waste of resources to a certain extent

Abstract

The invention belongs to the field of domestic waste treatment and disposal and recycling, and relates to a device for accelerating to stabilize incineration residue of domestic waste by utilizing acid waste gas. The device mainly comprises a waste gas storage tank, a valve, a rotor flow meter, an aerator, a temperature control device, a temperature probe, a stirrer, a stirring paddle, a feed opening, a discharge opening, an exhaust port, a pressure gage and a reactor. The device has the advantages of simple structure, reliable principle, easiness in operation, simplicity in operation and lowcost, and the stabilizing process of the incineration residue can be accelerated; sealing storage of greenhouse gases such as carbon dioxide and the like is realized; and the application environment is friendly.

Description

Technical field: [0001] The invention belongs to the field of domestic waste treatment and resource utilization, and relates to a device for accelerating and stabilizing domestic waste incineration residues by using acid waste gas. technical background: [0002] With the improvement of people's living standards, the amount of domestic waste generated in my country has increased year by year. Domestic waste incineration residue refers to the residue produced during the process of domestic waste incineration, mainly including incineration slag and incineration fly ash. Incineration slag is the residue directly discharged from the hearth after domestic waste incineration, as well as the ash discharged from the superheater and economizer, and its production accounts for about 5-25% of the waste incineration; The bottom ash settled at the bottom of the collection, flue and chimney accounts for about 3-5% of the waste incineration. Incineration slag contains less easily leached ...
