Description
Technical field
The utility model is the other filtering system of a kind of recirculated water.
Background technology
At present, the heat that produces in the equipment operation process in the commercial production mainly adopts the mode of recirculated water cooling, and cooling water will produce a large amount of suspended impurities in the process of constantly circulation, have a strong impact on heat exchange function.
The processing method of suspended impurity mainly is to add medicament such as Biocidal algae-killing agent in the recirculated water entry position in the recirculated water, reduces the suspended impurity in recirculated water with this.Yet; In whole process of production; Owing to make-up water fail thoroughly clear, exposure position have in the air fly into, bacterial micro-organism and corpse, owing to pipeline is revealed and many reasons such as come off of Corrosion results, cause recirculated water in hydronic process, to sneak into a large amount of suspended impurities.The too high harm that is prone to cause of recirculated water suspension: on the metal surface of (1) foundry loam attached to condenser, reduce cooling effect, unit vacuum is reduced, the end difference rises, thereby influences the economy of unit.(2) on the filler of foundry loam attached to condenser cannon born or cooling tower, stop up cooling-water duct, thereby the water yield is reduced and the resistance to water-flow increase, promptly increased with electric consumption and reduced cooling effect again.(3) when foundry loam during, cause metal erosion or concentration cell corrosion under the deposit easily on the one hand, can reduce the scale inhibitor effect on the other hand attached to the condenser metal surface.Also can increase the consumption of antisludging agent.
The utility model content
The utility model purpose: the purpose of the utility model is to propose the other filtering system of a kind of recirculated water, reduces the content of suspension in the cooling circulating water, guarantees the cooling effect of equipment.
Technical scheme: for solving the problems of the technologies described above, the other filtering system of the recirculated water that the utility model proposes comprises the female pipe of circulating water cooling tower backwater; Above that branch be provided with a water supply line, the mouth of a river is provided with into water distributor box under this water supply line, the mouth of a river is provided with the U-shaped pipe under the water inlet distributor box; The U-shaped pipe is connected into filter, and this filter is arranged in the other filter, and other filter is provided with an outlet pipe and is connected into clear water reserviors; Siphon tedge one end is connected with the filter water inlet, and the other end is connected with the siphon down-comer, is connected into flashback tank at last; On the siphon tedge, also be connected with auxiliary siphon tube; Exhaust tube is connected with this auxiliary siphon tube, in other filter, also is provided with siphon destructing tube, and this siphon destructing tube is connected with exhaust tube.
At this filter water inlet inlet damper is set.
Siphon tedge caliber is greater than U-shaped pipe caliber.
Beneficial effect: the other filtering system of the recirculated water of the proposition of the utility model; With the by-pass flow water yield that distributes certain water yield in the circulating cooling system; Utilize the filtrate of loading in the other filter that the suspension in the water is carried out filtration treatment; Recirculated water is through the operation of certain hour, and it is limpid that cycle water can become, and suspension will remain on below 3 PM in the water.This system moves simple easy operating, and need not the water pump pressurization, and its operation and backwash are automatic operation, calculate from long-time running and can reduce operating cost.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1, the other filtering system of this recirculated water comprises the female pipe 1 of circulating water cooling tower backwater, and branch is provided with a water supply line 3 above that; 3 times mouths of a river of this water supply line are provided with into water distributor box 4, and 4 times mouths of a river of water inlet distributor box are provided with U-shaped pipe 5, and U-shaped pipe 5 is connected into filter 6; At these filter 6 water inlets inlet damper 14 is set, this filter 6 is arranged in the other filter 7, and other filter 7 is provided with an outlet pipe 2 and is connected into clear water reserviors 15; Siphon tedge 8 one ends are connected with filter 6 water inlets, and the other end is connected with siphon down-comer 12, is connected into flashback tank 13 at last; On siphon tedge 8, also be connected with auxiliary siphon tube 10; Exhaust tube 9 is connected with this auxiliary siphon tube 10, in other filter 7, also is provided with siphon destructing tube 11, and this siphon destructing tube 11 is connected with exhaust tube 9.Siphon tedge 8 calibers through the effect of siphon, make upper water get into water level district under the filter rapidly through the backwash feed pipe fast greater than U-shaped pipe 5 calibers, arrive the automatic backwash purpose.
Former water gets in the filter 6 in the other filters 7 through water supply line 3 and water inlet distributor box 4, at filter 6 water inlets inlet damper 14 is set, and prevents that current from directly washing away filter, prolongs filter service life.Former water is through the top-down filtration of filter 6 filtering layers, and the back gets into other filter 7, is full of the back and goes into clear water reserviors 15 through outlet pipe 2.Filtering layer constantly stays suspension; Cause resistance to increase, and impel the water level in the siphon tedge 8 constantly to raise, when water level reaches auxiliary siphon tube 10 mouths of pipe; Water falls from this pipe;,, just siphonage takes place and make water carry out backwash through filtering layer to filtrate from bottom to top when vacuum reaches certain value so as to taking away the air in the siphon down-comer 12 through exhaust tube 9.When siphon destructing tube 11 was reduced in the other filter of flushing 7 underwaters, air got into siphon tedge 8, destroys siphonage, and backwash finishes, and filtration restarts.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
