Description
Technical field
This utility model belongs to Coal Chemical Industry technology field, is specifically related to a kind of tower bottom liquid position and maintains device.
Background technology
Wet desulphurization is the desulfurization technology that during modern chemical industry produces, popularization degree is wider, and the water gas after heating up pressurization enters
It is the important procedure being subjected to that row cooling processes.
Desulfurizer uses water cooling tower to lower the temperature high-temperature water gas, i.e. tower top is passed through the recirculated water that temperature is relatively low,
Contact with from the reverse water gas entered at the bottom of tower and conduct heat.In process of production, certain altitude can be formed bottom cooling tower
Liquid level, in order to prevent, liquid level is too high needs level monitoring, to prevent water face from can cause blocking higher than water gas inlet ductwork.Tradition
Control method be to discharge in installation pipeline at the bottom of tower, and on pipeline, install valve group additional with regular discharge or interlocking is set carries out
Discharge.But, regulation valve group is relatively low if there is problem or degree of regulation aborning, then in causing tower, liquid level is inaccurate
Fluctuate, use valve group to be adjusted also increasing the workload of operative employee simultaneously.
For these reasons, design invents a kind of new process program to facilitate the operation normal production of guarantee just to seem particularly
Necessary.
Summary of the invention
In order to solve the unmanageable problem of cooling tower liquid level, the invention provides a kind of new tower bottom liquid position and maintain dress
Putting, including being sequentially connected with cooling tower and waste water reclaiming device, described cooling tower top is provided with water gas outlet and recirculated water
Import；Water gas import and circulating water outlet it is provided with bottom described cooling tower；Described circulating water outlet is by pipeline a even
Connect waste water reclaiming device；It is provided with control valve on described pipeline a；Described pipeline a connects vertical pipeline b；Described
On pipeline b, connection has pipeline c；The tower bottom liquid position using this structure maintains device, and in can making tower, liquid level keeps stable, is not required to
Want operative employee to dig-in liquid level, effectively prevent pipeline from building the pressure.
To achieve these goals, the technical scheme that the present invention takes is as follows:
A kind of tower bottom liquid position maintains device, including being sequentially connected with cooling tower and waste water reclaiming device, described cooling tower top
Portion is provided with water gas outlet and circulating water intake；Water gas import and circulating water outlet it is provided with bottom described cooling tower；
Described circulating water outlet connects waste water reclaiming device by pipeline a；It is provided with control valve on described pipeline a；Described
Pipeline a connects vertical pipeline b；The end of described vertical pipeline b is drain；On described pipeline b, connection has pipeline c；
Described pipeline c end is floss hole.
During use, the water gas that temperature is higher enters in cooling tower by the water gas import bottom cooling tower,
Lowered the temperature after carrying out transmission of heat by contact with the low-temperature circulating water entered from tower top, and after tower top is discharged into
Continuous workshop section.And recirculated water after heat exchange can form the liquid level of certain altitude, if liquid level is higher than water gas import at the bottom of tower therewith
Pipeline a can be caused to build the pressure.A vertical pipeline b was added, separately away from the bottom of pipeline b before design control valve group on pipeline a
Portion is that the position of 5.2m connects a pipeline c.
Normal enter tower water gas pressure when producing between 42kpag ~ 52kpag, water gas import away from the bottom of cooling tower away from
From h1For 1m, for ensureing when water gas pressure is minimum, recirculated water fluid column will not have water gas import then to need pipeline c peace
The position h of dress2For
42*103+ρgh1=ρgh2
Wherein ρ=1000kg/m
g =10N/ kg
h1=1m
Through calculating h2=5.2m。
When cooling tower normally works, the control valve group on pipeline a is closed, and pipeline b can connect with at the bottom of cooling tower, now
Having a height in pipeline b is the fluid column of 5.2 m, and the waste water of tower inner bottom part can emit through pipeline c and make liquid level in tower
All the time certain height is maintained.The pressure that fluid column produces bottom pipeline b can maintain 52Kpag(p=ρ gh all the time2), as long as
Water gas pressure (pressure entering tower water gas is generally 42kpag ~ 52kpag) the not higher than 52Kpag entering tower would not cause tower
Interior gas is scurried into pipeline b and is caused accident, and when entering pressure tower less than 52kpag, in tower, liquid level can maintain certain height simultaneously
Degree, as long as it is 1m that the pressure entering tower water gas is not less than liquid level in 42Kpag(now tower) water would not be caused to enter pipeline cause
Build the pressure.The recirculated water waste water that the most whole device process produces can be discharged through waste water reclaiming device.
The tower bottom liquid position using this structure maintains device, and in can making cooling tower, liquid level keeps stable, it is not necessary to behaviour
Workmanship dig-ins liquid level, effectively prevents pipeline from building the pressure, and can also reliably be completely cut off with the external world by gas in cooling tower simultaneously,
Prevent security incident from occurring.
In sum, in this process unit can make cooling tower, liquid level keeps stable, it is not necessary to operative employee dig-ins liquid level,
Effectively prevent pipeline from building the pressure, gas in cooling tower reliably can also be completely cut off with the external world simultaneously, prevent security incident
Occur.

Embodiment 1
During use, the water gas that temperature is higher enters in cooling tower by the water gas import bottom cooling tower,
Lowered the temperature after carrying out transmission of heat by contact with the low-temperature circulating water entered from tower top, and after tower top is discharged into
Continuous workshop section.And recirculated water after heat exchange can form the liquid level of certain altitude, if liquid level is higher than water gas import at the bottom of tower therewith
Pipeline a can be caused to build the pressure.A vertical pipeline b was added, separately away from the bottom of pipeline b before design control valve group on pipeline a
Portion is that the position of 5.2m connects a pipeline c.
When cooling tower normally works, the control valve group on pipeline a is closed, and pipeline b can connect with at the bottom of cooling tower, now exist
Having a height in pipeline b is the fluid column of 5.2 meters, the waste water of tower inner bottom part can through pipeline c emit make tower in liquid level begin
Maintain certain height eventually.The pressure that fluid column produces bottom pipeline b can maintain 52Kpag all the time, as long as entering the water coal of tower
In atmospheric pressure not higher than 52Kpag would not cause tower, gas is scurried into pipeline b and is caused accident, is less than when entering pressure tower simultaneously
During 52kpag, in tower, liquid level can maintain certain height, as long as the pressure entering tower water gas is not less than in 42Kpag(now tower
Liquid level is 1m) water would not be caused to enter pipeline cause and build the pressure.
