Sampling VOC control and treatment system for vinyl chloride monomer tank car

Abstract

The invention relates to the technical field of vinyl chloride, and discloses a sampling VOC control and treatment system for a vinyl chloride monomer tank car. The system comprises a placement device; moving devices are fixedly connected to the two sides of the placement device; an adsorption device is fixedly connected to the middle of the upper surface of the placement device; a limiting deviceis fixedly connected to one side of the lower surface of the placement device; and the other side of the lower surface of the placement device is fixedly connected with a locking device. Through theadsorption device on the placement device, a worker can adsorb part of toxic gas more conveniently, meanwhile, subsequent recovery can be performed more conveniently, then, the condition of direct discharge of a traditional device is effectively avoided, and then the environment is protected; and through the limiting device and the locking device on the placement device, the worker can erect and lean against corresponding equipment more conveniently and lock the equipment, so that the equipment is effectively protected, and meanwhile, the operation burden of the worker is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of vinyl chloride, in particular to a VOC control and treatment system for sampling a vinyl chloride monomer tank car. Background technique [0002] Vinyl chloride, also known as vinyl chloride, is an important monomer used in polymer chemical industry. Its chemical formula is C2H3Cl, and it can be prepared from ethylene or acetylene. It is a colorless, easily liquefied gas with a boiling point of -13°C, a critical temperature of 151.5°C and a critical pressure of 5.57MPa. The relative density is 2.2%. Vinyl chloride is a toxic substance, long-term inhalation and exposure to vinyl chloride may cause liver cancer. It forms an explosive mixture with air, the explosion limit is 3.6%-33% (volume), and it is more likely to explode under pressure. During storage and transportation, attention must be paid to the airtightness of the container and nitrogen seal, and a small amount of polymerization inhibitor should...
