Abstract
The utility model relates to a shunted circulation water horizontal flow cooling tower, which is composed of a shell, a fan, a water collector, a water spraying layer, a flow sieving layer, a shutter and a water pool. The inner chamber of the horizontal flow cooling tower comprises the water collector and the flow sieving layer, the water collector is a circular ring multilayer bridging plate type, and the flow sieving layer is provided with a circular ring multilayer flow sieving structure. The utility model has the advantage of small flow resistance of cold air, the cold air is vertical to the circulation water current through the flow sieving layer. Owing to the large upper part and the small lower part of the water collector, the air volume can be uniformly distributed, so the derivative coefficient is large, the cooling effect is good, and the circulation water amount is increased.
Description
The utility model is a kind of shunting recirculated water crossflow cooling tower, belongs to cooling device.
The cooling crossing current tower (as shown in Figure 2) of existing quantity of circulating water more than 500T/h is made up of housing 7, blower fan 1, water collection device 2, water spray layer 3, packing layer 4, blind window 5, pond 6 etc.The multi-layer honeycomb shape that packing layer 4 connects for hollow, the cooling air shuttles back and forth in the middle of packing layer 4 and recirculated water carries out the caloic exchange, promptly cooling off air and recirculated water is to flow in the plastics of same packing layer 4, see that according to the gas of existing circulating water cooling tower, the dynamic characteristic of elementary stream there is following irrational situation in it: the flow resistance of (1) air is big; (2) drag characteristic owing to upper and lower packing layer equates that so cause under the effect of fan, the air capacity that flows through the upper strata is bigger than the air capacity of lower floor in the crossing current tower, then cause to make upper strata air capacity surplus, and the situation of lower floor's air capacity deficiency; (3) under the condition of the flow area that guarantees the cooling air, recirculated water is shorter residence time in packing layer 4; (4) according to the above, cooling air and recirculated water can not be admixed fully, therefore, just can not fully improve its cooling effectiveness;
In order to overcome the problem of above-mentioned existence, the purpose of this utility model: go under the condition in identical gas-water ratio, improve the cold effect of former circulating water cooling tower; Under identical cooling air volume and equal cold effect condition, improve its quantity of circulating water.
The purpose of this utility model is achieved in that the utility model is a kind of shunting recirculated water crossflow cooling tower (as shown in Figure 1), is made up of housing 7, blower fan 1, water collection device 2, water spray layer 3, sieve fluid layer 4, blind window 5 and pond 6.The inner chamber of crossflow cooling tower comprises water collection device 2 and sieve fluid layer 4 closely linking into an integrated entity outside; Receive water layer 2 and reach the fishplate bar formula, form less down for the mutual left-hand thread of bent plate and more than keeping certain spacing relatively and being segmented on the staged and reach fishplate bar (as shown in Figure 3) for the annulus multilayer; Its air water trend; Water (flow) direction is flowed into by the straight openend of bent plate formula; Airflow direction is flowed into by bent plate formula curved openings end.Sieve fluid layer 4 is an annulus multi-deck screen flow structure (as shown in Figure 4), and every layer of structure of multilayer is waveform flat-plate, has the circle perforation at the trough place of waveform flat-plate.Water collection device 2 and sieve fluid layer 4 all adopt slim corrosion resistant plate or aluminium alloy plate.The technical solution of the utility model is to adopt the form of gas, moisture stream.Recirculated water is the method that adopts multi-deck screen stream from top to down, and residence time prolongation and current the exposed area in space of recirculated water in tower body increased, and is 500T/h as quantity of circulating water, and its exposed area is 641 square metres.Sieve fluid layer 4 adopts slim corrosion resistant plate or aluminium alloy plate compacting to form, and its thermal conductivity factor is far longer than the thermal conductivity factor of plastic filler layer 3.The aerodynamically principle, the flow direction of cooling air adopts perpendicular to sieve fluid layer 4 directions in the crossing current tower, the pressure field that effect is produced according to fan is reasonably distributed its resistance field (being the structural configuration of water collection device 2) then, makes the cooling air volume distributed uniform on the vertical plane that sieves fluid layer 4.The shunting of employing air water makes the flow resistance minimum of cooling off air.
The utility model compared with prior art, its advantage: (1) adopts gas, moisture stream, and cooling-air resistance is reduced; (2) the cooling air adopts the vertical direction at sieve fluid layer 4 to flow in the crossing current tower, the pressure field that effect is produced according to fan, the structural configuration that reasonably to distribute its resistance field be water collection device 2 goes up many few stepped constructions down, makes the cooling air volume distributed uniform on the vertical plane of sieve fluid layer 4; (3) recirculated water adopts layering screen stream, and sieve fluid layer 4 adopts slim corrosion resistant plate or aluminium alloy plates, the recirculated water surface area is increased, and the thermal conductivity factor of metal is big more than plastic filler layer 3 thermal conductivity factor, so gas, the exchange of hydro-thermal matter are best; (4) air quantity of fan and static pressure go into the tower body gas-flow resistance to design by optimum gas, water ratio, to guarantee that circulating water cooling tower is moved in the best condition; (5), make its life-span (more than 10 years, not changing sieve fluid layer 4) be far longer than plastic filler layer 3, and annual maintaining expense reduce, operational reliability improves because sieve fluid layer 4 adopts slim corrosion resistant plate; (6) the utility model can be used for the design of New Cycle water cooling tower, is suitable for the energy saving technical reconstruction of existing circulating water cooling tower again.
Accompanying drawing of the present utility model:
Fig. 1 is the utility model general illustration.
Fig. 2 is the prior art general illustration.
Fig. 3 is Figure 1A-A enlarged drawing.
Fig. 4 is Figure 1B-B enlarged drawing.
The technical solution of the utility model confirms as follows through test:
In the rare factory of second of Shanghai general petrochemicals factory, after the cement Revamping Cooling Tower of former 2000T/h, can on original technical indicator basis, quantity of circulating water be brought up to 2500T/h.
