above-mentioned tower reactor heat exchanger is tubular heat exchanger or finned heat exchanger or jacketed type exchanger.
the utility model reasonable and compact in structure, easy to use, by making full use of the recirculated water by the liberated heat heating of vinyl chloride workshop section, can effectively save energy consumption, extended the production cycle, realize safety in production, the benefit that has further improved the rectifying of vinyl chloride high-boiling components, has larger economic worth.
Brief description of the drawings
accompanying drawing 1 is the main TV structure schematic diagram of the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is vinyl chloride batch fractionating tower, and 2 is high-temperature-hot-water pipe, and 3 is storage tank, and 4 is outlet pipe, and 5 is cold water pipe, and 6 is vinyl chloride workshop section circulating water device, and 7 is delivery pump.
Detailed description of the invention
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is to be all described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this vinyl chloride high-boiling components Finestill energy-saving apparatus comprises vinyl chloride batch fractionating tower 1, carries high-temperature-hot-water pipe 2 and vinyl chloride workshop section circulating water device 6 by the recirculated water of vinyl chloride workshop section liberated heat heating; In the tower reactor of vinyl chloride batch fractionating tower 1, be installed with tower reactor heat exchanger, on tower reactor heat exchanger, there are respectively the import of heat exchanger thermal source and the outlet of heat exchanger thermal source, the port of export of the import of high-temperature-hot-water pipe 2 and vinyl chloride workshop section circulating water device 6 is fixedly installed togather, the outlet of high-temperature-hot-water pipe 2 and the import of heat exchanger thermal source are fixedly installed togather, in the outlet of heat exchanger thermal source, be installed with outlet pipe 4, on high-temperature-hot-water pipe 2, be installed with delivery pump 7, the entrance point of delivery pump 7 is communicated with high-temperature-hot-water pipe respectively with the port of export.Vinyl chloride workshop section liberated heat is taken out of by recirculated water, recirculated water becomes high-temperature-hot-water like this, enter vinyl chloride workshop section circulating water device 6 with the recirculated water of heat, by high-temperature-hot-water pipe 2 in delivery pump 7 is delivered to tower reactor heat exchanger, as the thermal source of vinyl chloride batch fractionating tower 1 tower reactor, avoid adopting separately steam to heat as thermal source, like this, by utilizing the waste heat that produces in the course of production of chloroethylene thermal source as vinyl chloride batch fractionating tower 1 tower reactor, can save energy consumption, the recirculated water being heated by vinyl chloride workshop section liberated heat is after the tower reactor heating to vinyl chloride batch fractionating tower 1, send through outlet pipe 4.
