Combustion device for waste precipitation in sewage treatment

Abstract

The invention discloses a combustion device for waste precipitation in sewage treatment, which comprises a positive pressure combustor and a fan, the positive pressure combustor is formed by combining a combustor body and a control part, the combustor body is of a cavity structure, the control part is arranged at the front end of the combustor body, an air distribution part is arranged at the rear end of the combustor body, and the fan is arranged at the front end of the combustor body. A gas distribution part is arranged at the upper end of the burner body, a first connector and a second connector are arranged on the control part, the upper end of the gas distribution part is connected with gas supply equipment through a gas pipe, and the gas flows from the gas supply equipment to the burner on the gas pipe; the positive displacement fan is adopted at the air distribution part to replace a conventional centrifugal fan, and the positive displacement fan has the characteristic of equal air supply, so that the pressure change of the air outlet and the air supply amount are basically kept unchanged, the air quantity for combustion is ensured, and the problem of incomplete combustion is avoided.

Description

technical field [0001] The invention relates to the technical field related to sewage treatment, in particular to a combustion device for sewage treatment and sedimentation waste. Background technique [0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering And other fields, more and more have entered the daily life of ordinary people. With the stricter environmental protection requirements, but with the complexity of pollutants in sewage, the cost of sewage treatment is also getting higher and higher, especially It is high-concentration and viscous sewage. When concentrated by evaporation, the conventional surface heat exchange evaporator has serious crystal scaling on the surface and cannot maintain...

AI Technical Summary

Problems solved by technology

Such a combustion method is stable and controllable, but after it is arranged underwater, due to the effect of water pressure, the side pressure of the flue gas is significantly higher than the flue gas environment of the conventional combustion device, which makes the flow of the flue gas turbulent, and the gas volume and air volume are out of balance, causing the combustion device Problems of unstable combustion, flameout, backfire and even gas leakage
