AI Technical Summary

Technical Problem

When existing sludge spray guns spray sludge, the sludge is prone to spray into strands, and the diffusion effect is poor, which is not conducive to sludge incineration.

Method used

A spray gun device for a sludge back-spray combustion system is designed, including a spray gun body and a spray head. A diffusion chamber is provided in the injection nozzle. The inner diameter of the diffusion chamber gradually increases along the direction of the sludge spraying. The spray end of the spray head is inserted into the diffusion chamber, and the sludge is diffused around by a circular diffusion chamber.

Benefits of technology

Effectively diffuse the sludge sprayed from the nozzle to prevent the sludge from being sprayed out in strands, improve the coverage area of ​​the sludge, facilitate combustion, and improve the sludge incineration effect.
