Abstract
The invention relates to a technology and equipment for producing bis(trichloromethyl)carbonate through hermetical condensation and continuous packaging. A completely chlorinated chloride material is delivered into a circulating pump unit through a feed inlet and a feed pipe, the circulating pump unit comprises an intermediate tank and a circulating pump, the material is pumped into hermetical condensation conveying equipment through a master feed inlet and cooled and solidified into a solid material, the non-solidified material returns to the circulating pump unit, the seal condensation conveying equipment is provided with an air inlet and an air outlet, the air outlet is directly connected with an induced draft fan which can deliver gas containing various pungent odors into a tail gas absorption device to be treated and exhausted, the solid material enters a roll-in crusher and is crushed into fine particles, fine particles enter a bucket elevator, the material is elevated in the bucket elevator and enters a stock bin, and the fine material enters a packaging machine under the gravity action so as to be directly packaged and warehoused.
Description
The present invention relates to a kind of sealed condensating and pack continuously the Processes and apparatus of producing two (trichloromethyl) carbonic ether, belong to chemical field.
Technical background: two (trichloromethyl) carbonic ether is the high material of reactive behavior; can substitute phosgene carries out as chemical reactions such as chloromethane esterification, carbonic acid esterification, isocyanation esterification, isocyanide, chlorination, chlorine formylations; because the toxicity of phosgene is very high; risk and harm that leakage occurs in transportation are very large, and with two (trichloromethyl) carbonic ether, replacing phosgene has been trend of the times.At present, the method of domestic production two (trichloromethyl) carbonic ether is interrupter method, and a plastic tank is directly put in chlorination completely material, then naturally cooling after 24 to 56 hours material condensation-crystallization become solid, by workman, material is poured out from bucket again, manually smashed rear hand-filling.Complete in order to ensure chlorination, chlorination later stage chlorine must be excessive, simultaneously owing to being accompanied by the generation of by product two phosgene in chlorination reaction process, so must be mixed with a small amount of two phosgene and chlorine in chlorizate two (trichloromethyl) carbonic ether, two phosgene and chlorine all have strong impulse smell, therefore blowing and packing shop environment are very severe, and conventional packing work need be dressed the hermetically sealed protective clothing packing shop of being allowed for access and be carried out the work.The strong impulse smell of two phosgene and chlorine also causes the severe environment of in factory and surrounding area.
The object of this invention is to provide a kind of sealed condensating and pack continuously the Processes and apparatus of producing two (trichloromethyl) carbonic ether, the weak point existing to solve existing Technology.
Summary of the invention: the technique that a kind of sealed condensating of the present invention is packed production two (trichloromethyl) carbonic ether continuously comprises the following steps:
(1) by chlorination completely chloride material by feed opening, tremie pipe, enter recycle pump group, recycle pump group is comprised of tundish and recycle pump etc.;
(2) material is squeezed into condensation sealing handling equipment by recycle pump through total feed opening, material is cooled and solidifies out into solid materials at this, not solidified material returns to recycle pump group, condensation sealing handling equipment is provided with blast inlet and air outlet, air outlet is directly connected with induced draft fan, and induced draft fan is sent the gas that contains various pungent odours into device for absorbing tail gas and processed rear emptying;
(3) solid materials enters rolling disintegrator, and material is fractured into tiny particle at this;
(4) tiny granule materials enters bucket elevator, and material is raised and goes forward side by side into feed bin at this;
(5) tiny material enters wrapping machine by feed bin and directly packs warehouse-in under the effect of gravity.
Tool of the present invention has the following advantages:
1, realized production process serialization, production process is relatively stable;
2, because chloride material is directly to enter condensation sealing handling equipment in pipeline in reactor, and condensation sealing handling equipment is hermetically sealed equipment, so material without being exposed in air but complete packing warehouse-in in Sealing Arrangement, has improved workman's labour intensity greatly;
3, because condensation sealing handling equipment is provided with blast inlet and air outlet, air outlet is directly connected with induced draft fan, and it is rear emptying that induced draft fan is sent the gas that contains various pungent odours into device for absorbing tail gas processing, improved greatly workman's production and living environment.
The equipment that sealed condensating of the present invention is packed the technique of producing two (trichloromethyl) carbonic ether is continuously: by recycle pump group (1), condensation sealing handling equipment (2), rolling disintegrator (3), bucket elevator (4), feed bin (5), the compositions such as wrapping machine (6), wherein recycle pump group (1) is connected with condensation sealing handling equipment (2) by pipeline, condensation sealing handling equipment (2) is directly connected with rolling disintegrator (3) by tremie pipe, rolling disintegrator (3) top is connected with condensation sealing handling equipment (2) by pipeline, bottom is connected with bucket elevator (4) by pipeline, bucket elevator (4) is connected with feed bin (5) by pipeline, feed bin (5) is connected with wrapping machine (6) by pipeline.
Accompanying drawing is described as follows:
Accompanying drawing is processing unit schematic diagram of the present invention, and wherein (1) is that recycle pump group, (2) are that condensation sealing handling equipment, (3) are that rolling disintegrator, (4) are that bucket elevator, (5) are that feed bin, (6) are wrapping machines.
Below by embodiment, further comment:
1, by chlorination completely chloride material by feed opening, tremie pipe, enter recycle pump group, recycle pump group is comprised of tundish and recycle pump etc.;
2, material is squeezed into condensation sealing handling equipment by recycle pump through total feed opening, material is cooled and solidifies out into solid materials at this, not solidified material returns to recycle pump group, condensation sealing handling equipment is provided with blast inlet and air outlet, air outlet is directly connected with induced draft fan, and induced draft fan is sent the gas that contains various pungent odours into device for absorbing tail gas and processed rear emptying;
3, solid materials enters rolling disintegrator, and material is fractured into tiny particle at this;
4, tiny granule materials enters bucket elevator, and material is raised and goes forward side by side into feed bin at this;
