It protects and is equipped with the first valve 7 between valve 6, water inlet pipe 3 is equipped with inflow temperature sensor 8 and water inlet maintenance valve 9, inflow temperature
Be equipped with the second valve 10 between sensor 8 and water inlet maintenance valve 9, the setting of back purge system 2 water inlet pipe 3 and return pipe 4 it
Between, 2 one end of back purge system is arranged on the return pipe 4 between return water temperature sensor 5 and the first valve 7, back purge system 2
The other end is arranged on the water inlet pipe 3 between inflow temperature sensor 8 and the second valve 10, the first valve 7 and the second valve 10
For normally opened valve, return water safeguards that valve 6 and water outlet maintenance valve 9 are manually-operated gate.
Further, back purge system 2 includes the Backwash pipeline 11 of connection water inlet pipe 3 and return pipe 4, Backwash pipeline
11 are equipped with third valve 12 at return pipe 4, and Backwash pipeline 11 is equipped with the 4th valve 13, third valve at water inlet pipe 3
Backwash pipeline 11 between door 12 and the 4th valve 13 is equipped with drainpipe 14, and drainpipe 14 is equipped with the 5th valve 15, row
14 tail end of water pipe is equipped with effluent pit 16, and third valve 12, the 4th valve 13 and the 5th valve 15 are normal closed gate.
Further, the water inlet pipe between back purge system 2 and inflow temperature sensor 8 is equipped with filter 17.
In the technical scheme, back purge system can reduce by 90% or more manual maintenance workload, while can also improve
About two orders of magnitude of equipment dependability achieve the effect that avoid production heavy losses completely.
It is as follows that principle is embodied:
Automatic back-flushing function detects 3 temperature of temperature value t15 and water inlet pipe according to water cooler return pipe 4 by system controller
The temperature difference t=t15-t14 for spending t14 is controlled, when temperature difference t reaches 1 normal temperature difference upper limit Δ T of water cooler, Δ T
For system process parameters (parameter is known parameters), system controller PLC starts water cooler automatically and carries out backwashing function
(in addition to this, the condition of system starting backwashing function may also be configured to timing start mode, and the specific time can be according to actual use
Situation starts the period it is arranged.According to the actual situation, temperature difference control and time control mode can also be set simultaneously).
Backwashing function includes that inversely backwash circuit and positive flush loop, reverse backwash are that is, net by water return pipeline 4
Recirculated water is inversely through manually-operated gate 6, normally opened valve 7, heat exchanger 1, water filter 17, normal closed gate 13, normal closed gate 15, most
Afterwards by sundries and it is dirty be discharged into effluent pit 16, inversely backwash circuit in: normally opened valve 7 is not charged, normally opened valve 10
Electrification, normally opened valve 10 are closed, and inlet pipeline net circulating water and heat exchanger disconnect at this time, this road is different；At the same time, normally closed
Valve 12 is without electricity, and non-water flow passes through in Backwash pipeline, normal closed gate 13 and 15 electric-opening, pipeline are connected, backwash
Pipeline is cooled by water after device, filter by the recirculated water in water return pipeline to be flowed through pipeline and finally flows back in effluent pit 16.Because at this time
Inlet pipeline disconnects, and the flow and flow rate for flowing through water cooler and filter is all larger, plays the fast flush work to its runner
With peeling off impurity and dirty pressure, while the large scale impurity deposited in the filter is also flushed in effluent pit together；Just
To flushing, i.e., by the recirculated water forward direction of water inlet line through manually-operated gate 9, normally opened valve 10, water filter 17, heat exchanger 1, often
Valve closing door 12, normal closed gate 15 are finally discharged into effluent pit 16, in positive flush loop: normally opened valve 10 is not charged, often
Valve opening door 7 charges, and normal closed gate 13 is not charged, and normally opened valve 7 and normal closed gate 13 are in closed state, at this time water return pipeline
Water is in an off state, this road is different；At the same time, normal closed gate 13 is not charged, anhydrous in pipeline to flow through, 12 He of normal closed gate
Normal closed gate 15 obtains electric-opening, and pipeline is connected, and positive flushing pipeline is by the recirculated water in inlet pipeline after filter, water cooling
Device flows through pipeline and finally flows back in effluent pit 16.Because water return pipeline at this time disconnects, flow through water cooler and filter flow and
Flow velocity is all maximum, plays the strong souring to its runner, peels off impurity and dirty pressure.
Each complete backwash process includes back flush-forward direction flushing-three stage of back flush.In water cooler
Under formal starting backwash mode, reverse backwash stage is carried out first, in each back flush period, back flush 3~5
Secondary, each duration is 10~20 seconds, and positive rinse stage, each positive flushing week are immediately entered after the completion of back flush
Interim, forward direction is rinsed 3~5 times, and each duration is 10~20 seconds；After the completion of forward direction is rinsed, final reverse punching is finally entered
It washes the stage, in the final back flush period, back flush 1~2 time, each duration is 5~15 seconds, final back flush
Pipeline and valve are restored to normal condition after the completion.
It should be noted that, in this document, relational terms such as first and second and the like are used merely to a reality
Body or operation are distinguished with another entity or operation, are deposited without necessarily requiring or implying between these entities or operation
In any actual relationship or order or sequence.Moreover, the terms "include", "comprise" or its any other variant are intended to
Non-exclusive inclusion, so that the process, method, article or equipment including a series of elements is not only wanted including those
Element, but also including other elements that are not explicitly listed, or further include for this process, method, article or equipment
