Description
Technical field
The utility model relates to a kind of water coolers, and in particular to a kind of water cooler by-pass valve and back purge system.
Background technique
In Chemical Manufacture, the effect of water cooler is that temperature of charge is dropped to thermal material by way of exchanging heat with recirculated water
Temperature is needed to production, since runing time is too long, the problems such as circulating water quality, water cooler tube bank can assemble one in use process
, there is scale formation in a little impurity, influence water-cooled cooling effect, need to stop work and clean to water cooler tube bank.
In Chemical Manufacture, rectifying tower top material is cooled down first after air cooler is cooling, then water cooled device is cooled to process requirement
Temperature, since winter ambient temperature is relatively low, material temperature after air cooler is cooling is lower than circulating water temperature, then water cooled device
After heat exchange, temperature rises, and original design water cooler material import and export is without by-pass, when water cooler restrains leakage or material is not required to cooling,
Water cooler cannot be cut off.
Utility model content
The purpose of this utility model provides a kind of water cooler by-pass valve and recoil aiming at defect of the existing technology
Cleaning device.
Its technical solution is: tube bank inside a kind of water cooler by-pass valve and back purge system, including water cooler and water cooler,
The input terminal of water cooler is connected with water inlet pipe, and water inlet pipe is equipped with inlet valve, and the right end water inlet pipe of inlet valve is equipped with
The back flush valves of branch, the output end of water cooler are connected with outlet pipe, and outlet pipe is equipped with flowing water Valve, water inlet pipe with go out
Recirculated water looped pipeline is equipped between water pipe, water cooler is equipped with material inlet pipe and material outlet pipe, and material outlet pipe is equipped with discharge valve
Material inlet pipe is equipped with the first material inlet valve, and material is equipped between material inlet pipe and material outlet pipe and conveys looped pipeline, material conveying is secondary
Pipe is equipped with the second material inlet valve.
The water cooler multiple can be used in series.
Compared with prior art, having the advantage that design property reasonable, simple and practical in structure is strong.It will
Water cooler material import and export adds material to convey looped pipeline, when water cooler restrains leakage or material is not required to cooling, opens the second inlet valve
Door closes the first material inlet valve and discharge valve, cuts off water cooler；Inlet valve is closed, flowing water Valve and backwash valve are opened
Door is filled the water from water outlet pipe part, is discharged from back flush valves, is backwashed to water cooler, periodically flushes out tube bank impurity
Come, solves water cooler and restrain fouling, make device longtime running.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Specific embodiment
Referring to Fig.1, tube bank 7, water inside a kind of water cooler by-pass valve and back purge system, including water cooler 6 and water cooler
The input terminal of cooler 6 is connected with water inlet pipe 1, and water inlet pipe 1 is equipped with inlet valve 3, sets on the right end water inlet pipe of inlet valve 3
There are the back flush valves 5 of branch, the output end of water cooler 6 is connected with outlet pipe 2, and outlet pipe 2 is equipped with flowing water Valve 4, into
Recirculated water looped pipeline 12 is equipped between water pipe 1 and outlet pipe 2, water cooler 6 is equipped with material inlet pipe 8 and material outlet pipe 10, and material goes out
Pipe 10 is equipped with discharge valve 14, and material inlet pipe 8 is equipped with the first material inlet valve 9, sets between material inlet pipe 8 and material outlet pipe 10
There is material to convey looped pipeline 11, material conveys looped pipeline 11 and is equipped with the second material inlet valve 13.
The water cooler 6 multiple can be used in series.
The course of work: when water cooler restrains leakage or material is not required to cooling, opening the second material inlet valve 13, close first into
Expect that valve 9 cuts off water cooler 6；When water cooler 7 dirts of tube bank are more, inlet valve 3 is closed, flowing water Valve 4 and backwash are opened
Valve 5 fills the water from outlet pipe 2, is discharged from back flush valves 5, backwashes to water cooler 6, will periodically restrain impurity
It develops, solves water cooler and restrain 7 foulings, make device longtime running.
