Abstract
The utility model relates to a cooling device for the chemical production specifically is an ejection of compact cooling device at bottom of cyclohexanol separation tata, has solved the ejection of compact of current cyclohexanol knockout tower and has not had the problem that there is the potential safety hazard in cooling arrangement. Ejection of compact cooling device at bottom of cyclohexanol separation tata includes the tower cauldron pump that communicates with the cyclohexanol knockout tower, and the output of tower cauldron pump is provided with the back pressure regulating valve rather than the intercommunication, and back pressure regulating valve's output is provided with the DN20 seamless steel pipe rather than the intercommunication, and DN20 seamless steel pipe overlaps in the outside to have and is 5.8 meters DN50 cooling jacket, the circulation outlet pipe and the circulation inlet tube that distribute about the DN50 cooling jacket lateral wall is provided with rather than tip an organic whole and length. The utility model has the advantages of reasonable design reliably, through addding cooling device for ejection of compact temperature reduces by a wide margin at the bottom of the refined tata of cyclohexanol, and operation and production actual demand are satisfied in the emergence of having stopped the potential safety hazard, have simple structure, the convenient just advantage with low costs of processing.
Description
Technical field
The utility model relates to Chemical Manufacture refrigerating unit, is specially cooling device for discharging at the bottom of a kind of hexalin knockout tower tower.
Background technology
At the bottom of hexalin knockout tower tower, during tower bottoms extraction, temperature reaches 162.2 DEG C, and traditional working method is by direct for still liquid ton bag, without cooling apparatus, easily scalds during operation, there is potential safety hazard.
Summary of the invention
There is the problem of potential safety hazard in the utility model, provides cooling device for discharging at the bottom of a kind of hexalin knockout tower tower without cooling apparatus in order to solve the discharging of existing hexalin knockout tower.
The utility model adopts following technical scheme to realize: cooling device for discharging at the bottom of hexalin knockout tower tower, comprise the tower reactor pump be communicated with hexalin knockout tower, tower reactor delivery side of pump is provided with the back pressure regulating valve be communicated with it, the output terminal of back pressure regulating valve is provided with the DN20 weldless steel tube be communicated with it, outside DN20 weldless steel tube, cover has with its end one and length is the DN50 cooling jacket of 5.8 meters, and DN50 cooling jacket sidewall is provided with recycling outlet and the circulation water inlet pipe of left and right distribution.
During operation, at the bottom of hexalin treating tower tower, produced quantity is 42.3kg/h, temperature is 162.2 DEG C, after in tower reactor pump discharge length being the DN50 cooling jacket of 5.8 meters, temperature out can be down to less than 60 DEG C, meet operation and production actual demand, overcome the discharging of existing hexalin knockout tower exists potential safety hazard problem without cooling apparatus.
The utility model reasonable in design is reliable, by setting up refrigerating unit, drop temperature at the bottom of hexalin treating tower tower significantly being reduced, has stopped the generation of potential safety hazard, meet operation and production actual demand, there is simple, the easy to process and advantage that cost is low of structure.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-tower reactor pump, 2-back pressure regulating valve, 3-DN20 weldless steel tube, 4-DN50 cooling jacket, 5-recycling outlet, 6-circulation water inlet pipe.
