Ventilation purification device of laboratory

Abstract

The invention discloses a ventilation purification device of a laboratory, and relates to the technical field of air purification. The ventilation purification device comprises a tank body, wherein a partition plate is fixedly mounted in the inner cavity of the tank body; the tank body is divided into an absorption chamber and a drying chamber through the partition plate; a fixing plate is fixedly mounted at the bottom of the inner cavity of the absorption chamber; an absorption tank is fixedly mounted at the bottom of the inner cavity of the absorption chamber and between the fixing plate and the partition plate; a rotating shaft is rotationally connected inside the fixing plate; the right end of the rotating shaft penetrates through the fixing plate and extends to the part above the absorption tank; a rotating cylinder is fixedly mounted at the upper end of the rotating shaft; a connecting tube is arranged in the center of the right side wall of the rotating cylinder; the right end of the connecting tube penetrates through the partition plate and extends into the drying chamber; a filtering cotton net is arranged inside the side wall of the rotating cylinder. While the rotating cylinder is rotated, the filtering cotton net is rotated, then the filtering cotton net contacts an absorption solution inside the absorption chamber continuously, the absorption efficiency is improved, and relatively thorough air purification is achieved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a laboratory ventilation and purification device. Background technique [0002] Air purification refers to providing overall solutions for various indoor environmental problems such as sterilization and disinfection, dust and haze removal, harmful decoration residues and peculiar smells, so as to improve living and office conditions and improve physical and mental health. Indoor environmental pollutants and pollution sources mainly include radioactive gas, mold, particulate matter, decoration residue, second-hand smoke, etc.; divided into five materials: PP filter paper, glass fiber, composite PP PET filter paper, melt-blown polyester non-woven fabric and melt-blown glass fiber. Can filter particles of specific particle size; Grafting polymer polymerization technology: Adsorb the problematic substances that produce odor and pollution to its own carrier, and produce a che...
