Description
Technical field
The utility model relates to a kind of circulating water jet vacuum equipment, belongs to chemical production technical field.
Background technique
Water jet vacuum equipment, has that energy consumption is low, structure is simple, compact, reliable operation, maintenance is simple, vacuum while, poisonous and harmful tail gas absorption can be proceeded to the advantages such as aqueous phase process, widely use in Chemical Manufacture.Especially relating to hazardous chemical production field that is inflammable, explosive, poisonous, that be harmful to, have corrosion, many unit operations carry out under negative pressure (vacuum), and the application of water jet vacuum equipment is more extensive.
Water jet vacuum equipment, when other emergency case such as meeting power failure, misoperation suddenly cause stopping, instantaneously by the water suck-back in water jet vacuum equipment in vacuum line, entering reactor, decompression distillation still or vacuum drier etc. uses in the equipment of vacuum, light then affect quality of product, heavy then cause security incident.Such as, when decompression distillation acyl chlorides, as water suck-back enters decompression distillation still, acyl chlorides is acutely hydrolyzed and produces a large amount of gas, can set off an explosion.
For anti-sealing jet vacuum equipment generation suck-back, usually solenoid valve or one-way valve etc. are set on vacuum line.Solenoid valve is in open mode when power transmission normally works, the automatic-closing valve when having a power failure; One-way valve also known as safety check or check valve, for preventing reverse fluid flow.Solenoid valve and one-way valve have a common shortcoming, and that is exactly due to complex structure, and during unlatching, inlet and outlet pressure loss is comparatively large, and namely degree of vacuum declines more, virtually adds energy consumption, reduces application area.
So far, for requiring high vacuum operation, being strictly on guard against the occasion that steam flows backwards, the decompression distillation of such as higher boiling acyl chlorides, the vacuum drying of low melting point solid, powdery material, there is no suitable water jet vacuum equipment.
