Efficient degassing structure for glass fiber reinforced plastics production workshop

Abstract

The invention discloses an efficient degassing structure for a glass fiber reinforced plastics production workshop. The efficient degassing structure comprises a workshop roof and a ventilation unit,wherein the ventilation unit is located inside the workshop roof; five groups of longitudinal rods and four groups of horizontal rods are erected inside the ventilation unit; exhaust fans are fixedlyarranged at multiple groups of junctions between the longitudinal rods and the horizontal rods. The efficient degassing structure for the glass fiber reinforced plastics production workshop is provided with the ventilation unit, a petroleum hydrocarbon dissolving chamber, a perforated speed reducing plate and a rotating motor, and a large number of exhaust fans are started periodically to eliminate harmful gases in the workshop in a centralized way. Petroleum hydrocarbon adsorbents are used for effectively absorbing exhausted styrene gas, and the perforated speed reducing plate can prolong theresidence time of air bubbles in the dissolving chamber by blocking effect. Four groups of fan blades are driven to rotate by an output shaft to produce suction force for increasing the air filteringspeed at an activated carbon filtering structure, thereby improving the gas treatment amount. The efficient degassing structure can adapt to different working conditions, and has a better applicationprospect.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a high-efficiency degassing structure for a glass fiber reinforced plastic production workshop. Background technique [0002] The resin used in the production of FRP is unsaturated resin, which contains styrene monomer. When painting, styrene overflows and produces organic waste gas. These waste gases are irritating and harmful to the body of the workers in the production workshop. It will affect health, and it will be directly discharged into the environment without treatment, which will also cause environmental pollution. Therefore, it is necessary to regularly ventilate the production workshop; the existing common method for treating styrene gas is to use activated carbon to adsorb, but the The adsorption effect is not good, and the gas treatment capacity is large, and the filter screen needs to be replaced frequently, which is time-consuming and laborious, and brings c...

Problems solved by technology

[0002] The resin used in the production of FRP is unsaturated resin, which contains styrene monomer. When painting, styrene overflows and produces organic waste gas. These waste gases are irritating and harmful to the body of the workers in the production workshop. If it is directly discharged into the environment without treatment, it will also cause environmental pollution, so it is necessary to regularly ventilate the production workshop; the existing common method for treating styrene gas is to use activated carbon to absorb, but the The adsorption effect is not good, and the gas processing capacity is large, and the filter screen needs to be replaced frequently, which is time-consuming and laborious, and brings certain adverse effects during use. Therefore, we propose a high-efficiency degassing structure for FRP production workshops
