Air humidifying, dust washing and cooling device provided with sprayed grass core

Abstract

An air humidifying, dust washing and cooling device provided with a sprayed grass core is composed of the grass core, a spraying unit, a top box, a fan, a bottom box, a water pan, a water pump, a water supply tube and a primary filter. The top box and the bottom box are installed at the top and the bottom of the grass core to seal the top surface and the bottom surface of the grass core correspondingly. The spraying unit is arranged in the top box and connected with the water pump through the water supply tube. Circulating spraying is conducted by circulating water in the water pan. The primary filter is arranged at an air suction port of the grass core, and filtered air enters the grass core. The water pan is arranged under the grass core. Water sprayed out by the spraying unit is partially attached to the surface of grass and partially flows downwards along gaps of the grass, spraying water flowing out of the grass core is collected to the bottom box and flows back to the water pan to be used repeatedly or be drained. When the fan works, air is forced to pass through the wet surface of the grass and the inter-grass gaps to be filtered and washed, so that the comprehensive effects that the air is humidified, dust is removed and the temperature is decreased are achieved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning fresh air equipment, in particular to an air humidifying, dust cleaning and cooling device for an air-conditioning fresh air system. Background technique [0002] In densely populated places such as classrooms in primary and secondary schools, it must be introduced 30m from the outside 3 / h / personal fresh air (fresh air) to meet hygiene and health requirements. The introduction of fresh air from the outside in haze weather will bring the fine dust harmful to health into the room. At present, indoor air purifiers with better dust removal effect are mainly porous media adsorption purifiers, which need to be used in confined spaces with closed doors and windows. In this way, in densely populated places, the effect of dust removal cannot offset the harm caused by the lack of fresh air. For this reason, patent 201420123356.X proposes an air dust washing device for air-conditioning fresh air...

AI Technical Summary

Problems solved by technology

However, the above-mentioned washing device is not filled with any filter material. When the operating condition is unstable, it will cause problems such as insufficient air washing and deterioration of the dust removal effect; if it is filled with ordinary filter materials such as non-woven fabrics, water will be absorbed in the filter. In the pores of the material, the air flow resistance is greatly increased, resulting in a sharp attenuation of the fresh air volume.
