Description
Technical field
The utility model is related to the vapour-recovery units after a kind of heat exchange.
Background technology
In the current Chemical Manufacture in China, the usage amount of steam is very big, meanwhile, it is big because using in some production processes
The saturated vapor of amount keeps the temperature equipment, after the heat exchange the generated condensed water also water vapour containing high heat.It is right
In the processing of these steam, general enterprises are all directly discharged in air, and this random processing not only polluted environment, simultaneously
It is also a kind of significant wastage to resource.
Invention content
Shortcoming in for the above-mentioned prior art, the utility model provide the Steam Recovery dress after a kind of heat exchange
It puts, it is simple in structure, it can effectively solve environmental pollution and the problem of resource waste of high heat steam.
In order to achieve the above object, the utility model employs following technical scheme：
A kind of vapour-recovery unit after heat exchange, it is characterised in that：Including packed tower, hot water storgae, cold rinse bank, water pump；
The packed tower is internally provided with packing layer, and cooling water nozzle is equipped with above described filler layer, is equipped with and does not coagulate at the top of the packed tower
Gas exports, and top is equipped with cooling water inlet, and lower part is equipped with steam inlet, and bottom is equipped with condensation-water drain；At the top of the hot water storgae
Equipped with steam (vapor) outlet, upper part is additionally provided with hot water inlet, and the cold rinse bank top is equipped with condensation water inlet, overfall；It is described cold
But water inlet is connected to the water pump by pipeline, and the water pump other end is linked by pipeline in the cold rinse bank；It is described
The condensation water inlet of cold rinse bank is connected to the condensation-water drain of the packed tower；The steam inlet of the packed tower is connected to described
The steam (vapor) outlet of hot water storgae.
Further, described filler layer is located in the middle part of the packed tower, and the filling rate of described filler layer is not less than 75%.
Further, the cooling water nozzle includes the multiple nozzles being evenly arranged along spiral pipeline.
The beneficial effects of the utility model include：Easy to operate, control is stablized, and is effectively reduced the wasting of resources, is reduced vision
Pollution, steam condensate (SC) can be used as refrigerant again.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is further described with reference to specific embodiment and attached drawing.
Vapour-recovery unit after a kind of heat exchange as shown in Figure 1, including packed tower 1, hot water storgae 2, cold rinse bank 3, water
Pump 4；Packed tower 1 is internally provided with packing layer 101, and 101 top of packing layer is equipped with cooling water nozzle 105, and 1 top of packed tower is equipped with not
Solidifying gas outlet 104, top are equipped with cooling water inlet 106, and lower part is equipped with steam inlet 102, and bottom is equipped with condensation-water drain 103；
2 top of hot water storgae is equipped with steam (vapor) outlet 202, and upper part is additionally provided with hot water inlet 201；3 top of cold rinse bank is equipped with condensation water inlet
301st, overfall 302；Cooling water inlet 106 is connected to water pump 4 by pipeline；4 other end of water pump is linked into cold water by pipeline
In slot 3；The condensation water inlet 301 of cold rinse bank 3 is connected to the condensation-water drain 103 of packed tower 1；The steam inlet 102 of packed tower 1
Connect the steam (vapor) outlet 202 of hot water storgae 2.
A kind of preferred embodiment, in the production process of dimethyl sulfoxide (DMSO), a large amount of saturated vapors used are to rectifying
After equipment and pipeline carry out heat exchange, the steam condensate (SC) containing a large amount of waste heats, which is collected, to be entered in hot water storgae 2, in hot water storgae
Steam condensate (SC) continues to evaporate, and is entered again into pipeline from the steam inlet 102 of packed tower 1 by the steam (vapor) outlet 202 of hot water storgae 2
Packed tower 1.Water pump 4 works simultaneously, and cooling water is extracted out from cold rinse bank 3, enters packed tower from cooling water inlet 106 through pipeline
1 top, and then cooling water is sprayed from cooling water nozzle 105.In order to make cooling water sprinkling uniform, cooling water nozzle 105 includes more
It a nozzle and is evenly arranged along spiral pipeline.The packing layer 101 of hot steam and cooling water at 1 middle part of packed tower carries out gas-liquid and connects
It touches, wherein the filling rate of packing layer is not less than 75%, the packing layer of the present embodiment preferably 80% filling rate.Gaseous steam and liquid
Water is condensed after being come into full contact on filler, reaches Steam Recovery effect, and control liquid water spray flux reaches gas-liquid phase equilibrium,
Reduce the wasting of resources.The condensation-water drain 103 of condensed condensed water from 1 bottom of packed tower flows out, then condensed water inlet
301 enter cold rinse bank 3.Remaining incondensible gas is directly arranged from the fixed gas outlet 104 at 1 top of packed tower after absorption
It is empty.Condensed water into cold rinse bank 3 can be extracted out by water pump 4 as cooling water Reusability again, wherein extra condensed water from
The outflow of overfall 302 reduces the wasting of resources for other equipment with this.
The technical solution provided above the utility model embodiment is described in detail, used herein specifically
A example is expounded the principle and embodiment of the utility model embodiment, and the explanation of above example is only applicable to help
Assistant solves the principle of the utility model embodiment；Meanwhile for those of ordinary skill in the art, implement according to the utility model
Example, the there will be changes in specific embodiment and application range, in conclusion the content of the present specification should not be construed as
Limitation to the utility model.
