Laboratory air purification dedusting cover with automatic cleaning function

Abstract

The invention relates to the technical field of laboratory equipment and provides a laboratory air purification dedusting cover with an automatic cleaning function and a building method of the laboratory air purification dedusting cover. The laboratory air purification dedusting cover comprises a dedusting cover box body, an air blowing and dehumidifying unit, a dust-liquid collection unit and a water circulating cleaning unit and is fixed to the wall through a support device. Air flowing in the box body is accelerated through air blowers by means of the air blowing and dehumidifying unit, external air enters the box body through side nets and a filtering water curtain, PM2.5 or other particulate matter is dissolved and settled, the air enters a room through a dehumidifying assembly, the negative influence of too much water vapor on laboratory instruments is avoided, and interception and elution of contaminants are achieved; according to the dust-liquid collection unit and the water circulating cleaning unit, through a manner of providing a water flowing channel, a water body flows through the box body and the side nets, and the cleaning purpose is achieved; and a disinfectant is injected into the filtering water, and the function of degrading toxic substances in the air is achieved. By the adoption of the laboratory air purification dedusting cover with the automatic cleaning function and the building method, the method for removing the PM 2.5 or other particulate matter in the air can be provided, and the laboratory air purification dedusting cover and the method have the beneficial effects that the purification effect is good, and the secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to an automatic cleaning laboratory air purification dust removal cover and a construction method thereof. Background technique [0002] During chemical experiments, various unpleasant, corrosive, toxic or explosive gases are often produced. If these harmful gases are not discharged outside in time, it will cause indoor air pollution, affect the health and safety of experimenters, and affect the accuracy and service life of instruments and equipment. In order to prevent laboratory workers from inhaling or swallowing some toxic or unknown toxic chemicals, organisms, vapors, gases and particles (smoke, soot, dust and aerosols) and other substances, the pollutants must be covered with fume hoods and fume hoods. , The method of local ventilation is removed. For example, equipment such as plasma emission spectrometer and atomic absorption spectrometer, the ventilation faci...
