Spraying system for settling paint spraying booth waste gas particulate matters

Abstract

The invention discloses a spraying system for settling paint spraying booth waste gas particulate matters. The spraying system comprises spraying tower bodies and a spraying unit connected with the spraying tower body, wherein the bottom of each spraying tower body is provided with an air inlet and a water discharging opening; the top of the spraying tower body is provided with an exhaust opening;the spraying unit comprises a circulation water box; the circulation water box is positioned at the bottom of the spraying tower body; the circulation water box and the spraying tower body are connected in a dismountable way; the circulation water box is used for providing water for the spraying tower body and collecting water in the spraying tower body; the circulation water box is provided witha water inlet pipeline; a liquid level valve is arranged at a water outlet of the water inlet pipeline; the circulation water box is also connected with a liquid conveying pump; an outlet of the liquid conveying pump is connected with the upper part side wall, the middle side wall and the lower part side wall of the spraying tower body through pipelines. The spraying system consists of two spraying tower bodies in series connection; waste gas in a paint spraying booth can be subjected to double treatment; harmful substances in waste gas are greatly reduced; the harm to workers and environmentis reduced to the greatest degree.

Description

technical field [0001] The invention relates to the technical field of exhaust gas treatment in a paint spraying room, in particular to a spraying system for settling exhaust gas particles in a paint spraying room. Background technique [0002] Paint mist and organic waste gas pollution are mainly generated during the paint spraying process. The paint is atomized into particles under the action of high pressure. When spraying, part of the paint does not reach the surface of the sprayed object and disperses with the airflow to form a paint mist. The organic solvents in the paint mist—benzene, toluene, and xylene are highly toxic solvents. They are emitted into the air of the workshop during operation. After being inhaled by workers through the respiratory tract, they can cause acute and chronic poisoning, mainly causing damage to the central nervous system and hematopoietic system. Short-term inhalation of high-concentration (1500m} / ms) benzene vapor can cause aplastic anemi...

AI Technical Summary

Problems solved by technology

The harm of paint mist to workers cannot be ignored. The existing spray scrubbers have poor treatment effect on paint mist. It is necessary to take practical and feasible spray paint exhaust gas treatment measures to reduce pollutant emissions and reduce the impact of toxic and harmful substances on the health of spray workshop workers. harm
