Unsaturated polyester resin-tail gas purification control system

Abstract

The invention discloses a treatment device for tail gas containing styrene and other substances in reaction for producing orthophthalic type entanglement resin. The treatment device is mainly a tail gas exhaust measure adopted for meeting the environmental protection requirement in a chemical production process. The device comprises a tail gas collection master pipe, a vacuum tank, a vacuum pump, a water-vapor separator, an active carbon filter and an automatic control system. The orthophthalic type entanglement resin tail gas purification device effectively guarantees automatic control of tail gas treatment. The efficiency of purifying the tail gas is increased, and the environmental protection requirement of the tail gas purification can be realized through remote control. The purification degree is high when the tail gas is sucked by using negative pressure vacuum for treatment. One tail gas exhaust collection pipe is shared by a plurality of reaction kettles, so that the operation cost is low. The tail gas exhaust valve of each reaction kettle is independent and is controlled by a DCS (Distributed Control System). Negative pressure adsorptive filtration is adopted by the purification device, active carbon is used as an adsorbing material, and the adsorption rate to the styrene is over 90 percent. The disassembly and the assembly are facilitated, desorption can be performed under the action of 100 DEG C or under a vacuum condition after saturation, and the cyclic utilization rate is high.

Description

Technical field [0001] The invention relates to a tail gas treatment technology, in particular to a tail gas treatment technology containing styrene and other substances in the reaction of producing o-phthalic winding resin. It is mainly used in the exhaust emission measures taken to meet environmental protection requirements in the chemical production process. Background technique [0002] Existing exhaust gas treatment measures generally adopt spray absorption or activated carbon adsorption under standard conditions. Its disadvantages are low adsorption efficiency, high operating cost, low automation, and difficult control of process conditions. Summary of the invention [0003] The purpose of the present invention is to provide a tail gas purification device in the o-benzene type winding resin reaction, so as to solve the substandard tail gas emission caused by the low adsorption efficiency, high operating cost and low degree of self-control in the prior art.
