Abstract
The utility model provides a water -cooling tower device of getting rid of dirty nitrogen gas, includes high -pressure plate heat exchanger and low pressure plate heat exchanger, and high -pressure plate heat exchanger and low pressure plate heat exchanger connect the lower end inlet department at the water -cooling tower through the pipeline respectively all the way, and another sweetgum fruit is crossed emptying pipeline and is emptyyed, be connected with circulating water network management line at the last end inlet of water -cooling tower end, the water -cooling tower top is provided with drain, and the exit end of water -cooling tower is connected on the air cooling tower through freezing water pump, the dirty nitrogen gas that comes from the rectifying column upper column is lower through height plate heat exchanger heat transfer temperature, and from bottom to top flow sprays the downward flow with the water that comes from circulating water network management line from the water -cooling tower top, and the two direct contact had not only conducted heat but also the mass transfer, was a relatively more complicated process. Because the temperature of water is higher than the temperature of dirty nitrogen gas, has the direct water of following of heat and transfer dirty nitrogen gas on the one hand, make water obtain the cooling, the utility model has the characteristics of simple structure, convenient and practical.
Description
Technical field
This utility model is related to water-cooling tower dirt nitrogen elimination technique field, more particularly to a kind of water-cooling tower for excluding dirty nitrogen
Device.
Background technology
Designed according to current space division, the dirty nitrogen from tower on rectifying column enters after the heat exchange of height plate type heat exchanger
Water-cooled tower bottom, and top-down recirculated water heat and mass, so as to reduce the chilled water of circulating water temperature to 9 DEG C or so.Water
Chilled water is delivered to air cooling tower top by chilled water pump by the chilled water of cold tower bottom, with low-pressure air from bottom to top in air cooling
Exchanged heat in tower, and then reduced the temperature of low-pressure air.But because of design problem, current chilled water temperature is minimum to be down to 7 DEG C, cold
Freeze that coolant-temperature gage is too low that calcium ion will be caused to crystallize in solid form, cause to block distributor, pipeline and filter etc., finally
Cause system run well, cause system shutdown to overhaul.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a kind of water for excluding dirty nitrogen
Cold tower apparatus, by way of changing liquid to steam ratio, reduce the dirty nitrogen amount into water-cooling tower so that water temperature is improved, to reach technique
Require, with simple structure, the characteristics of convenient and practical.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of water-cooled tower apparatus for excluding dirty nitrogen, including high-pressure plate type heat exchanger 3 and low pressure plate type heat exchanger 4, high pressure
The blowdown nitrogen outlet end of plate type heat exchanger 3 and low pressure plate type heat exchanger 4 is connected to the dirt of 1 lower end of water-cooling tower all the way by pipeline
At nitrogen inlet, separately lead up to exhausting pipeline and be vented；Recirculated water is connected with the top recirculated water arrival end of water-cooling tower 1
Webmaster line, the top of described water-cooling tower 1 are provided with drain, and 1 lower section chilled water outlet end of water-cooling tower is by chilled water by cold
Freeze water pump 5 to be connected with the distributor inlet end of air cooling tower 6.
The height is vented by described exhausting pipeline is set in above 1 top drain of water-cooling tower and water-cooling tower 1 and circulates
At position between water inlet end.
Described exhausting pipeline is pipeline of the perforate with DN800.
Dirty nitrogen emptying control handss valve 2 is installed on described exhausting pipeline.
The beneficial effects of the utility model：
This utility model by exhausting pipeline, reduces the dirty nitrogen into water-cooling tower 1, that is, increases when chilled water temperature is not high
Big liquid to steam ratio, so as to improve the temperature of 1 bottom freeze water of water-cooling tower, it is to avoid cause calcium ion because chilled water temperature is too low with
Solid-state form is crystallized, and causes to block distributor, pipeline and filter etc.；System shutdown maintenance is it also avoid simultaneously.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Specific embodiment
Make narration in detail below in conjunction with the accompanying drawings to utility model works principle.
As shown in Figure 1：Dirty nitrogen from tower on rectifying column is changed through high-pressure plate type heat exchanger 3, low pressure plate type heat exchanger 4
After heat, temperature is about 25 DEG C, enters 1 bottom of water-cooling tower, now from high and low pressure heat exchanger before water-cooling tower 1 is entered after converging
At the top of the end socket of dirty nitrogen pipeline meet, pipeline of the perforate with DN800 is vented, and adds handss valve 2 to control into 1 dirty nitrogen of water-cooling tower
Flow, so as to be controlled to the chilled water temperature of 1 bottom of water-cooling tower, because the oxygen content in dirty nitrogen is only 0.6% or so, be
Unexpected generation is prevented, the absolute altitude of drain lifts most 16.7 meters at last.
Operation principle of the present utility model：
Water-cooling tower 1 is a kind of direct contact heat exchanger, from tower on rectifying column dirty nitrogen through high-pressure plate type heat exchanger 3,
Low pressure plate type heat exchanger 4 exchanges heat, temperature relatively low (25 DEG C), flowing from bottom to top, and carrys out self-circulating water net from the top of water-cooling tower 1
The Water spray of pipeline flows downward, the two directly contact, has not only conducted heat but also mass transfer, is a more complicated process.On the one hand by
Be higher than the temperature of dirty nitrogen in the temperature of water, just have heat directly dirty nitrogen to be passed to from water, cooled down water, on the other hand,
As dirty nitrogen is relatively dry, appropriateness only has 30% or so relatively, so the molecule of water can constantly evaporate, be diffused in dirty nitrogen
Go.And water accounts for evaporation and needs to absorb gasification latent heat, heat is taken away from water, the temperature for allowing for water is constantly reduced.
