Waste liquid combustion treatment system

Abstract

The invention discloses a waste liquid combustion treatment system. The system comprises a waste liquid combustion device, a heat recovery heat exchanger and a tail gas treatment device; the waste liquid combustion device comprises a collecting tank and a high-pressure air source, the collecting tank is connected with a waste liquid combustion furnace through a waste liquid pipe; the waste liquidcombustion furnace comprises a furnace body, a refractory mud layer is arranged on the inner wall of the furnace body, the lower end of the furnace body is closed, and an opening is formed in the upper end of the furnace body; the high-pressure air source communicates with the waste liquid pipe through a high-pressure air pipe, and an igniter is arranged at an opening of one end, extending into the furnace body, of the waste liquid pipe; the heat recovery heat exchanger comprises a heat exchange barrel which is vertically arranged; and the tail gas treatment device comprises a tower body, a water tank is arranged at the bottom of the tower body, a tail gas inlet is formed in the side wall of the tower body arranged on the water tank, two layers of porous plates are arranged at intervals inthe portion, above the tail gas inlet, of the tower body, a filling material is arranged on each porous plate, and the top end of the tower body is connected with a condenser through a tail gas outlet pipe. According to the system, liquid fuel waste liquid generated in a laboratory can be sufficiently combusted, heat generated by combustion can be recycled, and harmful components in the tail gascan be fully absorbed.

Description

technical field [0001] The invention relates to the technical field of waste liquid treatment, in particular to the combustion, heat recovery and tail gas purification technologies of laboratory liquid fuels. Background technique [0002] The laboratory often uses flammable and explosive liquid fuels. The common flammable and explosive liquid fuels in the laboratory include: benzene, toluene, methanol, ethanol, petroleum ether and acetone, etc. If the liquid fuel discarded after the experiment is discharged directly, it will pollute the environment and bring fire hazards. Burning waste fuel in a combustion furnace will generate a large amount of heat in a short period of time. If the heat is released directly into the air, it will cause a waste of energy, and cause a sharp rise in the temperature in the laboratory, resulting in a high temperature in the room. As the conditions deteriorate, it is necessary to further turn on the laboratory air conditioner to cool down, which...

If the liquid fuel discarded after the experiment is discharged directly, it will pollute the environment and bring fire hazards

Burning waste fuel in a combustion furnace will generate a large amount of heat in a short period of time. If the heat is released directly into the air, it will cause a waste of energy and cause a sharp rise in the temperature in the laboratory, resulting in a high temperature in the room. As the conditions deteriorate, it is necessary to further turn on the laboratory air conditioner to cool down, which leads to a waste of energy

[0003] At present, there is a lack of a combustion treatment system suitable for treating waste liquid fuels on the market
