Description

A kind of more effect condensers collected for gaseous product liquefaction

Technical field

The utility model relates to chemical products production equipment technologies, more particularly to a kind of liquefy for gaseous product to receive More effect condensers of collection.

Background technique

Gaseous product need to often be carried out to liquefaction in Chemical Manufacture and collect storage, such as low pressure liquefied gas boron chloride and Fuming liquids Boron tribromide is high-temperature gas product after reaction synthesis, need to be condensed into liquid with condenser in process of production It is collected in storage tank after state.Common design of condenser is the combination of inner tube and outer layer collet, and inner tube walks material, outside Layer collet is passed through cooling circulating water, and material carries out heat exchange with the cooling water of outer layer collet on inner layer tube wall, thus material from Gaseous state is condensed into liquid inflow storage tank and is stored；And common efficient condenser is then further added by one group of cooling in internal layer tube hub Pipe is to increase heat exchange area.But during the condensation of low pressure liquefied gas boron chloride and fuming liquids Boron tribromide is collected, Liquid material is during leaving condenser and falling to storage tank with certain potential energy and kinetic energy and in lower backward shock liquid level Vibration is generated, vaporized again after absorbing energy so as to cause liquid material and forms the tail with certain pressure in storage tank Gas.Smooth for rewinding, tail gas needs to vent gas treatment tank and to connect atmosphere from the dedicated offgas outlet pressure release of storage tank, and tail gas The pressure release of non-recovery measure reduces the rewinding rate of product and causes environmental pollution；Meanwhile to reduce liquid material free-falling Caused by vibration vaporization and certain particular/special requirements container condensation collect in, often in storage tank and collection vessel design stretch bottom Pipe carries out rewinding, and liquid material is allowed slowly to fall collections along stretching bottom tube inner wall, but when liquid level is higher than stretching bottom tube lower end discharge port When, often because the anomalous variation of temperature and pressure in reaction system and storage tank or container cause to stretch bottom tube can not blanking even By liquid form product along stretching bottom tube back-pressure to condenser or even reaction system to cause the abnormal even accident of production.Such low During pressing the condensation of liquefied gas and fuming liquids to collect, tail gas can not be solved simultaneously using only single common condenser and is returned Receive and stretch the problem of bottom tube returns liquid.
