Methylbenzene recycling device

Abstract

The invention discloses a methylbenzene recycling device. The right side surface of a body is fixedly provided with a gas exhaust tube in a penetrating mode; the inner wall of the gas exhaust tube isfixedly provided with a blocking ring; the top surface of the inner wall of the gas exhaust tube is fixedly provided with a vertical plate; an opening is formed in the lower end of the vertical plate;the inner wall of the opening is spliced with a slide rod; the right side of the slide rod is fixedly provided with a cover plate; the right side of the cover plate is fixedly provided with a rubberplug; the outer wall of the slide rod is sleeved with a second spring; the right side of the inner wall of the gas exhaust tube is spliced with a through tube; the left side of the outer wall of the through tube is fixedly provided with a rubber ring; the top surface of the inner wall of the through tube is fixedly provided with a supporting rod; the left side of the supporting rod is fixedly provided with an ejector rod; the upper surface of the through tube is fixedly provided with a sleeve; upper and lower ends of the through tube are fixedly provided with baffle plates; and the upper surface of the gas exhaust tube is fixedly provided with a fixed device. The methylbenzene recycling device provided by the invention can collect methylbenzene steam generated in methylbenzene production,guarantees collecting purity, and prevents methylbenzene steam in collection from being in contact with air to form impurities to affect the collecting effect.

Description

technical field [0001] The invention relates to the technical field of toluene production, in particular to a toluene recycling device. Background technique [0002] Toluene is an easy-to-obtain product in petrochemical production, and it is also a chemical intermediate with a large amount. However, with the improvement of people's requirements for the ecological environment, toluene, a by-product of petrochemical industry, cannot meet the quality requirements of food and cosmetics, and natural toluene cannot be directly extracted from animals and plants, and must be produced by chemical methods. The existing toluene production equipment is in The toluene vapor generated during production cannot be recycled well, and the recovery purity of the toluene vapor cannot be guaranteed. Explosive mixtures are likely to be produced during the collection process, and the safety of use cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to...
