Method for filtering water of odor treatment spray water tank

Abstract

The invention discloses a method for filtering water of an odor treatment spray water tank. The method comprises the steps of calculating a filter area of a DN50FIG-Y filter, and selecting a box-type filter which is applicable to the odor treatment spray tower water tank; dividing the sewage discharged from the spray tower water tank into two paths, filtering one path of sewage entering the DN50FIG-Y filter through a filter front stop valve, and filtering the other path of sewage entering the box-type filter through a water inlet stop valve of the box-type filter; generating 4bar spray water pressure by the filtered process water by utilizing a spray pump at a spray atomizing nozzle, filtering the sewage through a new box-type filter, and conveying the filtered water through the spray pump to a water spray position to be atomized so as to meet the sewage filter capacity requirement. The spray tower water tank is in a negative-pressure state in the working process, and the problem of water supply for cleaning a filter net in the production process can be solved.

Description

technical field [0001] The invention relates to a method for filtering water in a spray water tank for treating peculiar smell. Background technique [0002] The application of odor treatment equipment in the silk workshop has a significant effect on improving the tobacco smoking and removing miscellaneous gases. Use the odor treatment equipment to collect the odor of the waste gas of each process point, because the waste gas of these process points has a large dust content, resulting in poor water quality. [0003] In the existing technology: the sewage from the spray tower water tank passes through the original filter front gate and the original DN50Y type filter, and the filtered water is transported to the spray water stain by the water pump for atomization. [0004] Existing problems: the DN50FIG-Y type filter in front of the spray pump is blocked, the water supply of the water pump is insufficient, and the spray water pressure is reduced to 1.5bar, which cannot meet t...

AI Technical Summary

Problems solved by technology

[0004] Existing problems: the DN50FIG-Y filter in front of the spray pump is blocked, the water supply of the water pump is insufficient, and the spray water pressure is reduced to 1.5bar, which cannot meet the spray water pressure requirements

The original DN50Y filter was blocked by impurities in the water and could not meet the flow requirements of the pump, resulting in a decrease in the outlet pressure of the pump and affecting the spraying effect, requiring frequent shutdowns to clean the filter, resulting in reduced equipment efficiency and fluctuations in product odor absorption
