Abstract
The utility model discloses a kind of antifreeze reflux unit of spray column, and major cycle pipeline is equipped between the spray column and water tank；One end front end where definition spray column, one end where water tank are rear end；The front end area connection of the circulating line is located at several spray heads in spray column, and the major cycle pipeline between the spray column and water tank is equipped with a water circulating pump, and the front end area of the water circulating pump is equipped with a check-valves；A reflux branch is had additional on the major cycle pipeline, which is connected on major cycle pipeline, positioned at the front end area of check-valves, and the other end is connected on water tank；Reflux branch road is equipped with the valve of control reflux branch opening and closing.After the check-valves in spray column water circulating pump exit, installation flows back branch all the way, after allowing water circulating pump to shut down, liquid can thus road pipeline, individually return to the generation that ice condition is avoided without remaining in main pipeline in water tank.
Description
Technical field
The utility model belongs to sewage treatment field, and in particular to a kind of antifreeze reflux unit of spray column is mainly used for
In spray column circulation pipe under outdoor cold conditions.
Background technique
According to the applicant understood, traditional spray column after a shutdown, has check-valves (sometimes for anti-since water circulating pump exports
Only pipeline freezes, the not loaded check valve in circulating line, but if the liquid that circulating line flows back to can damage without check-valves
Impeller causes circulation pomp impeller to fall off), liquid residual is had in circulation pipe.If pipeline is in cold environment, especially
When spray column is located at the cold north, the liquid being exposed in yard piping is easy to after freezing and damages pipeline, and to subsequent
Spray column, which is restarted, also to be had an impact.
In consideration of it, proposing that a kind of antifreeze reflux unit of spray column is the project to be studied of the utility model.
Summary of the invention
The utility model provides a kind of antifreeze reflux unit of spray column, and its purpose is to solve in the prior art ask
Topic.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of antifreeze reflux unit of spray column, institute
It states and is equipped with major cycle pipeline between spray column and water tank；
One end where defining spray column is that one end where front end, water tank is rear end；The circulating line is from front to back
It is sequentially connected several spray heads being located in spray column, water circulating pump and water tank outside spray column, the water circulating pump
Front end area be equipped with a check-valves；
A reflux branch is had additional on the major cycle pipeline, which is connected on major cycle pipeline,
Positioned at the front end area of check-valves, the other end is connected on water tank；The reflux branch road is equipped with control reflux branch opening and closing
Valve.
Related content in above-mentioned technical proposal is explained as follows:
1, in above scheme, the valve is normally closed solenoid valve door.
2, in above scheme, the major cycle pipeline is divided into multistage, by being located at the spray section of spray column, the room being located outside
It outer segment and is formed by connecting positioned at indoor indoor section, the reflux branch, check-valves and water circulating pump are respectively positioned on indoor section.
3, in above scheme, the major cycle pipeline positioned at reflux branch front end area is equipped with a pressure gauge.
4, in above scheme, the bottom of the spray column offers a leakage fluid dram, connects between the leakage fluid dram and water tank
There is drain pipe.
Since above-mentioned technical proposal is used, the utility model has the advantage that compared with prior art
Compared with the prior art, after the check-valves in spray column water circulating pump exit, installation flows back the utility model all the way
Branch, after allowing water circulating pump to shut down, thus liquid can flow back branch, individually return in water tank without remaining in main circulation pipe
In road, the generation of ice condition is avoided.
Wherein, reflux branch is controlled by independent normally open solenoid valve, and valve is opened in water circulating pump stalling, solenoid valve power-off,
Thus liquid flows back branch reflow tank, fundamentally prevented the icing of major cycle pipeline raffinate.
Detailed description of the invention
It is attached that FIG. 1 is a schematic structural view of the utility model.
In the figures above: 1, spray column；2, major cycle pipeline；3, drain pipe；4, check-valves；5, water circulating pump；6, it flows back
Branch；7, valve；8, water tank；9, spray head；10, pressure gauge.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
A kind of embodiment: antifreeze reflux unit of spray column
Referring to attached drawing 1, major cycle pipeline 2 is equipped between the spray column 1 and water tank 8.
One end where defining spray column 1 is that one end where front end, water tank 8 is rear end；The front end of the circulating line 2
Region connection is located at several spray heads 9 in spray column 1, and the major cycle pipeline 2 between the spray column 1 and water tank 8 is equipped with
The front end area of one water circulating pump 5, the water circulating pump 5 is equipped with a check-valves 4.The bottom of the spray column 1 offers a row
Liquid mouth is connected with drain pipe 3 between the leakage fluid dram and water tank 8.
A reflux branch 6 is had additional on the major cycle pipeline 2, which is connected to major cycle pipeline 2
Above, positioned at the front end area of check-valves 4, the other end is connected on water tank 8.The reflux branch 6 is equipped with a control reflux branch
The valve 7 that road 6 is opened and closed, the valve 7 are normally closed solenoid valve door.
Wherein, the major cycle pipeline 2 divides for multistage, by the spray section for being located at spray column 1, the outdoor section being located outside and
It is formed by connecting positioned at indoor indoor section, the reflux branch 6, check-valves 4 and water circulating pump 5 are respectively positioned on indoor section.Positioned at return
The major cycle pipeline 2 for flowing 6 front end area of branch is equipped with a pressure gauge 10.
In working condition, reflux branch 6 is controlled by independent normally open solenoid valve, and water circulating pump 5 stalls, and electromagnetic valve is disconnected
Electricity is opened, thus liquid flows back 6 reflow tank 8 of branch, has fundamentally prevented the icing of 2 raffinate of major cycle pipeline, and in water pump 5
When normal work, electromagnetic valve is normally off, i.e. reflux branch 6 is normally closed.
