Safe purification system of laboratory air

Abstract

The invention discloses a safe purification system of laboratory air. According to the system, a control module detects the content of harmful substances in the air in a laboratory through an air detection module and judges whether the laboratory air is required to be purified according to the content of harmful substances and a comparing chart; if yes, the control module instructs and controls anair suction module to suck air in the laboratory, and a particulate matter detection module detects the real-time content of solid particulate matter in the air and compares the real-time content ofsolid particulate matter with a preset threshold value; when the real-time content of solid particulate matter is larger than the preset threshold value, the control module inducts and controls a particulate matter clearing module to clear solid particulate matter in the air until the real-time content of the solid particulate matter in the air is lower than a second threshold value, the control module instructs and controls a harmful substance purification module to purify harmful substances in the air, and an exhausting module exhausts the purified air.

Description

technical field [0001] The invention relates to the technical field of laboratories, in particular to a laboratory air safety purification system. Background technique [0002] Harmful gases, corrosive gases, and dust generated in the laboratory may cause great damage to the environment. In the process of processing harmful gases and corrosive gases, the harmful gases and corrosive gases in the laboratory are first passed through the suction fan. Inhalation, and then, through the air treatment system, the harmful gas and corrosive gas inhaled by the suction fan are purified, so that the harmful gas and corrosive gas become the gas that meets the emission standard. One problem with this treatment method is that, There are a certain amount of solid particles in the harmful gas and corrosive gas drawn in by the exhaust gas. These solid particles may not be able to be completely treated to meet the emission standards when they are treated by the air treatment system, and the tre...

[0002] Harmful gases, corrosive gases, and dust generated in the laboratory may cause great damage to the environment. In the process of processing harmful gases and corrosive gases, the harmful gases and corrosive gases in the laboratory are first passed through the suction fan. Inhalation, and then, through the air treatment system, the harmful gas and corrosive gas inhaled by the suction fan are purified, so that the harmful gas and corrosive gas become the gas that meets the emission standard. One problem with this treatment method is that, There are a certain amount of solid particles in the harmful gas and corrosive gas drawn in by the exhaust gas. These solid particles may not be able to be completely treated to meet the emission standards when they are treated by the air treatment system, and the treatment efficiency is low. In addition, these solid particles When the solid particles reach a certain concentration or the particles reach a certain particle size, they will cause damage to the related devices in the air treatment system, resulting in a low service life of the devices, which needs to be improved urgently
