Degree reaches process conditions.Being respectively different medium channels with pipe clamp inner room in heat exchanger tube, pipe clamp inner room is coolant guiding channel.
The most frequently used cooling medium is recirculated cooling water, and all grows when industrial cycle water quality is poor and have biological bacteria algae, float, foundry loam
In dirt, they are moved into cooler with recirculated water and are attached to pipe clamp and put, and long-term accumulation causes pipe clamp to overlap fouling, hinders
Medium heat-transfer；Light then cause heat exchange efficiency reduce, resistance increase affect device technique；It is heavy then cooler pipeline blockage can be caused,
Make cooling water flow reduce, have a strong impact on cooler heat transfer effect；Occur that compressor suction temperature at different levels is high, under production efficiency
Fall, the phenomenon that energy consumption increases；Chuck fouling produces the equipment safety problem such as underdeposit corrosion, superpressure shutdown, even breaks down and leads
Cause cooler is scrapped.Will be carried out cooler when running into these situations, current domestic conventional cleaning method is all to use
Coolant media is carried out, and one is that cooler chuck backwash, artificial backwash are simply simply changed by artificial back-flushing method
Become cooler inner cooling water to flow to, utilized the outer row of cooler discharge pressure adverse current to take dirt in chuck out of, reach cleaning and descaling
Purpose；Although only consuming recirculated water, but scale removal weak effect, cleaning quality it is difficult to ensure that, artificial backwash can only rise the short time
Effect, it is impossible to solve root problem；Another kind is chemically to be carried out cooler chuck, needs to use specialty power consumption
Equipment, adds and has the chemical solution of corrosiveness and carry out operation, although this method can remove pipe clamp set surface smut, but simultaneously
Heat exchanging equipment metal structure has directly etching effect, and chemical attack causes pipe clamp set smoothness to reduce, and heat exchanger tube weakness is rotten
Eating thrown hole, with artificially increase sealing factor, damage equipment is as good as；Additionally use chemical solution cleans time length and exist the most hidden
Suffer from, clean the chemical wastewater produced and be unfavorable for environmental protection treatment.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water cooler thermal washing energy-saving descaling device, overcomes existing
Some technological deficiencies, change technical thought, and the heat transfer coefficient utilizing different material is different, become the cleaning of traditional cold medium and are situated between into heat
Matter (steam) is heated thermal washing, and principle is to flow thermal washing pipe by steam by cooler tube chuck leads to physical method that steam heats
Chuck, because the heat conductivity of cooler base metal structure is higher than the heat conductivity of foundry loam dirt, is attached to metal pipe-wall and folder
The dirts such as the biological clay that puts, calcium carbonate, calcium phosphate, calcium silicates are under the common effect that metal structure heat conduction and steam are heated
Decomposes comes off naturally, and by blowing the steam jet that stifled steam pressure is formed, removes and be attached to the foundry loam dirt that pipe clamp puts
Dirt, and eject for Field Force's visual inspection from backwash valve.Cooler can improve cooling effect after thermal washing scale removal, reduces
SR, extension device service life, reaches energy-saving and cost-reducing purpose.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of water cooler thermal washing scale removal
Energy saver, including cooler, is provided with cooling water inlet pipe in the lower section of cooler, and the cooling water that is arranged at cooler goes out
Water pipe, is respectively equipped with water intaking valve and outlet valve in the lower end of cooling water inlet pipe and the upper end of cooling water outlet pipe；
Connecting on described cooling water outlet pipe and have jet chimney, cooling water inlet pipe connects has backwash pipeline, at steam
Pipeline is provided with steam and blows stifled valve, is provided with backwash valve on backwash pipeline.
Preferably, described cooler is shell and tube cooler.
Preferably, described cooler be respectively provided on two sides with gas feed and gas outlet.
Preferably, described jet chimney is passed through low-pressure steam.
This utility model has the advantages that
1, this utility model is compared with traditional chemical cleaning method, and steam heat washed journey safety coefficient is high, without acid-base class
Chemical spills pollutes environment；The washed journey of steam heat is harmless to cooler metal structure, without chemical attack.
2, the steam high temperature biological bacteria algae insect killing effect 100% to being attached on chuck, goes degerming algae mud to make cooler water
Chuck is unimpeded, and water quality is limpid, improves cooler heat exchanger effectiveness simultaneously, improves cooling effect, reduces SR, it is ensured that product
Technique, quality, energy-conservation more than 10%, make equipment safety Effec-tive Function.
3, steam thermal washing is without professional cleaning equipment, is not required to prepare chemical solution, without power consumption and other material consumptions, only needs on the spot
Drawing materials, consume a small amount of low-pressure steam, (the general factory of this condition has), small investment, cost is little, saves maintenance cost, saves
Scavenging period and cleaning frequency, minimum to Influence of production.
4, compared with artificial back-flushing method, use and add the method for steam and cooler tube chuck is heated thermal washing, dirty
Dirt decomposes under the common effect that metal structure heat conduction and steam are heated comes off naturally, blows the steam jet that stifled steam is formed
Pressure is high, flow velocity is fast, and scale removal effect is obvious, and dirt ejects can on-the-spot visually inspect from backwash valve after thermal washing scale removal, side
Assistant engineer skill management personnel judge cooler operation conditions.
5, can antirust, antiscale through thermal washing scale removal, it is to avoid cooler corrodes, damage, protect heat transmission equipment, cooler pipe clamp
After set thermal washing, after putting into corrosion inhibiter, equipment corrosion speed can be made to decline 90%, make service life of equipment extend one times.
6, energy-saving and water-saving, reduces cost.After cooler tube chuck thermal washing, removing scale removal, stoping incrustation scale to be formed, improve cold
But making compressor suction temperature at different levels reduce while effect, the amount of inflating is truer, and production efficiency improves, it is possible to reduce electric energy or
The consumption of power；Dirt is discharged Posterior circle water quality through thermal washing and is improved, and can improve recirculated water cycles of concentration, reduce recirculated water
Blowdown flow rate, improves recirculated water utilization rate.
