Abstract
The invention relates to a process and equipment for producing di(trichloromethyl) carbonic ester by sealing, condensing and continuously packaging. The process is as follows: a chloridized material which is fully chloridized enters into a circulating pump set through a feed opening and a feeding pipe, wherein the circular pump set consists of an intermediate tank, circulating pumps and the like; the material is pumped into condensing, sealing and conveying equipment by the circulating pumps by virtue of a total feed opening, wherein the material is cooled and condensed to a solid material while a non-condensed material is returned to the circular pump set; the condensing, sealing and conveying equipment is provided with an air inlet and an air outlet, wherein the air inlet is directly connected with an induced draft fan which sends various gases with pungent odors to a tail gas absorption device so as to be emptied and discharged; the solid material enters into a rolling smasher so as to be smashed to fine material particles which enter into a bucket elevator; the material is lifted to enter into a stock bin at the bucket elevator, and the fine material enters into a packaging machine from the stock bin under the effect of gravity so as to be directly packaged and put in storage.
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 replacing phosgene with two (trichloromethyl) carbonic ether 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 enter recycle pump group by feed opening, tremie pipe, recycle pump group is made up 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 by directly entering condensation sealing handling equipment in reactor in pipeline, and condensation sealing handling equipment is hermetically sealed equipment, so material without being exposed in air but complete packaging 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.
Brief description of the drawings is 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.
Further comment below by embodiment:
1, by chlorination completely chloride material enter recycle pump group by feed opening, tremie pipe, recycle pump group is made up 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;
