Abstract
The utility model relates to the technical field of heat recycling, and particularly relates to a light salt brine heat recycling device of an electrolytic cell. According to the technical scheme, the light salt brine heat recycling device comprises an in-cell salt brine pipeline connected with the electrolytic cell, wherein the other end of the in-cell salt brine pipeline is connected with a cold medium outlet of a first heat exchanger, a cold medium inlet corresponding to the cold medium outlet is connected with a refine salt brine pipeline, a hot medium inlet of the first heat exchanger is connected with a dechlorinated salt brine pipeline, and a hot medium outlet corresponding to the hot medium inlet is connected with a salt melting device through a pipeline. According to the light salt brine heat recycling device, an in-cell salt brine warming system is linked with a high-temperature light salt brine cooling system, and thus the consumption of steam and circulating cooling water can be simultaneously reduced, and the purposes of saving energy and reducing emission are achieved.
Description
Technical field
The utility model relates to the heat recuperation technical field, is specially a kind of electrolyzer light salt brine device for recycling heat.
Background technology
In the chlorine industry, the electrolyzer secondary brine of chlorine alkali workshop need to be controlled temperature at 72-73 ℃, normally adopts steam heating at present, and steam consumption is 1.2-1.3t/h.Light salt brine after simultaneously electrolysis temperature after dechlorination is regulated is about 85 ℃, delivers to primary brine salt, and needing the controlization brine temp is 60-65 ℃, needs recirculated cooling water to carry out cooling down.Said system has following drawback: (1), secondary brine need add heat rejection steam, cause energy dissipation, generate saturated brine when (3), high temperature light salt brine salt, are unfavorable for production run, must consume a large amount of recirculated water and cool off, and cause power consumption.
The utility model content
The purpose of this utility model is exactly the defective that exists for prior art, the electrolyzer light salt brine device for recycling heat that provide a kind of reasonable in design, save energy, reduces production costs.
Its technical scheme is: comprise the secondary brine pipeline of its connection of electrolyzer, the described secondary brine pipeline the other end connects the cold media outlet of First Heat Exchanger, and the cold medium import corresponding with it connects the refined brine pipeline; The thermal medium import of described interchanger connects dechlorination salt solution pipeline, and the thermal medium outlet corresponding with it is by pipeline connectionization salt device.
The second interchanger in parallel on the two ends pipeline of described First Heat Exchanger, and its thermal medium adopts steam.
Described interchanger is plate-type heat exchanger.
The utility model can reduce the consumption of steam and recirculated cooling water simultaneously with secondary brine temperature elevation system and the interlock of high temperature light salt brine cooling system, reaches the purpose of energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1, a kind of electrolyzer light salt brine device for recycling heat, refined brine is squeezed into the refined brine pipeline by refined salt water pump 1.1, it is divided into two-way, one of them branch road enters the cold medium inlet of plate-type heat exchanger 2.1, cold media outlet connects refined brine header tank 3 and electrolyzer 4 successively by the secondary brine pipeline, and wherein the hot media channel of plate-type heat exchanger 2.1 is communicated with steam-pipe; Another branch road enters the cold medium inlet of plate-type heat exchanger 2.2, cold media outlet is also incorporated on the secondary brine pipeline, the thermal medium import of plate-type heat exchanger 2.2 connects dechlorination salt solution pipeline and dechlorination brinepump 1.2, and thermal medium exports by pipeline connectionization brine tank 5.
During normal production, in the start-stop car process, open simultaneously the steam heat-exchanging system, refined brine is brought up to 72 ℃ about temperature after the heat exchange is by 63 ℃, satisfy the control requirement of secondary brine temperature; After stable, vapor heat exchanger can be converted to the dechlorination brine heat exchanger, vapor heat exchanger namely only is warmed up to 72 ℃ by 85 ℃ of light salt brines after the dechlorination to refined brine as for subsequent use, and while self temperature reduces; Also can open simultaneously in case of necessity two cover heat exchange systems, the complementary adjusting.
