Wind-assisted type spray gun for dust suppression and haze removal

Abstract

The invention discloses a wind-assisted type spray gun for dust suppression and haze removal. The wind-assisted type spray gun comprises an air duct (15), wherein the lower end of the air duct (15) isa spray gun connecting end (16), the top of the air duct (15) is provided with an air outlet (10), and the outer layer of the air outlet (10) is surrounded by a pressure equalizing water supply ringcylinder (14); and the top surface of the pressure equalizing water supply ring cylinder (14) is covered with a front cover (11), the side wall of the pressure equalizing water supply ring cylinder (14) is provided with a water inlet (13) connected to a metal hose, a plurality of nozzle connecting holes (12) are formed in the front cover (11) along the circumference, and the nozzle connecting holes (12) are properly inclined towards a center line of the air outlet (10). The wind-assisted type spray gun for dust suppression and haze removal has the advantages that after atomizing nozzles are installed, water mist can be blown and conveyed downwind so that wind energy can be overlapped with sprayed water energy, under the same wind power condition, the water mist blowing and conveying distance is lengthened, and under the same blowing conveying distance condition, the wind volume is small, the water consumption is small, and the energy consumption is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental treatment, and in particular relates to an air-driven spray gun, which is especially suitable for large-area spray dust removal and haze removal, and urban cooling operations. Background technique [0002] With the rapid development of industry, people's living standards and quality of life requirements are increasing day by day, a large number of urban populations gather, forest vegetation is cut down, air pollution is becoming more and more obvious, and cities are also covered with a layer of dust, especially in northern my country. In winter, a large amount of industrial waste gas is emitted, and smog and sandstorms are common, making the city always gray, affecting traffic safety, people's daily travel and physical health. Urban dust suppression, smog removal, and cooling work have also become key projects for urban residents and governments. The existing dust suppression and haze remova...

AI Technical Summary

Problems solved by technology

[0004] 1. The water mist generated after pressurization hinders the airflow, causing the high-speed wind energy and the sprayed water energy to cancel each other out, resulting in high power and high power consumption of the equipped jet fan;

[0005] 2. The gradually expanding air duct reduces the wind speed and reduces the spray distance. It is necessary to increase the air supply volume to meet the air supply distance requirements, resulting in a large diameter of the air outlet of the fog gun machine, large air volume, high water consumption, and serious waste of resources;

[0006] 3. The atomization direction of the spray device is fixed, and the vehicle-mounted fog cannon machine adopts car transportation and manual operation to change the atomization direction, which has high labor costs, and can only carry out dust suppression operations on roads and low altitudes, with a narrow scope of application

[0007] In addition, the fog cannon machine uses a high-power jet fan. The jet fan has a unique structure, which makes it impossible to silence the air inlet and outlet of the air cylinder. The operation noise is large and the people are seriously disturbed.
