Abstract
The utility model discloses a filtration device of a cooling tower. The filtration device of the cooling tower comprises a filter net and a recovery device. The filter net is hung above a water collecting pool. A remote end node and a proximal end node are arranged on the edge of offside of the filter net. The proximal end node is fixed on the side wall of the near-shore end of the water collecting pool. The recovery device comprises a fixed pulley which is fixed on side wall of the remote end of the water collecting pool. A hauling rope is mounted on the fixed pulley. One end of the hauling rope is connected with the remote end node of the filter net. Water entering the water collecting pool is all filtered through the filter net hung above the water collecting pool, size of the filter net is larger, and solid impurities in the circulating water are removed and circulation of the circulating water is ensured through using of the filter net with as far as small meshes. Due to the fact that cleaning of the filter net on-line can be realized through the recovery device, the filter net is convenient to clean and replace.
Description
Technical field
The utility model relates to the cooling device of the cooling tower, particularly cooling tower of the industries uses such as petrochemical industry, electric power.
Background technology
Now the cooling tower used of the industries such as petrochemical industry, electric power all be utilize the wind that blows into by on spill the water that gets off and form convection current, thermal source is drained, a part of water evaporates in convection current, has taken away corresponding evaporation latent heat, thereby the temperature of reduction water.Owing to lack protection, advance the wind of cooling tower and can carry the recirculated water that the impurity such as some plastic foils, leaf enter cooling tower secretly, and the filler of some packed tower self to be damaged owing to wearing out, some filler fragments also can enter recirculated water.At present, the main path that filters these impurity at cooling tower is in the water circulating pump porch of cooling tower collecting-tank filter screen to be set, owing to consider that the set filter screen mesh of the factors such as the looking up and down of water circulating pump, suction pressure can not be too small and can not on-line cleaning change filter screen, this enters circulation with regard to causing a part of impurity effectively not filter, and has a strong impact on heat transfer effect and the service life of heat exchanger.
Summary of the invention
The purpose of this utility model provides a kind of cooling tower filter, uses this filter can prevent that a large amount of impurity from entering circulation and having a strong impact on the heat transfer effect of heat exchanger and the problem in service life.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of cooling tower filter, comprise filter screen and retracting device, described filter screen is suspended on the top of collecting-tank, filter screen opposite side edge is provided with respectively far-end node and near-end node, the near-end node is fixed on the distolateral wall of collecting-tank offshore, described retracting device comprises the fixed pulley that is fixed on the collecting-tank far-end sidewall, and pull rope is housed on the fixed pulley, and an end of pull rope connects filter screen far-end node.
The utility model filters the water that enters collecting-tank entirely by the filter screen that is suspended on collecting-tank top, and the area of filter screen is larger, and uses the fine mesh filter screen to remove the solid impurity in the recirculated water and to guarantee the circulation of recirculated water as far as possible.Utilize retracting device can realize the on-line cleaning of filter screen, pack up by fixed pulley and traction good general filter screen, be convenient to cleaning and the replacing of filter screen.
The utility model can in the situation that guarantees circulation, filter and remove solid impurity in the recirculated water; Realize the efficient long-term operation of heat exchanger; Online change, cleaning is convenient and swift, also have investment little, be easy to the characteristics transforming and safeguard.
Description of drawings
Fig. 1 is the use view of the utility model cooling tower filter; Fig. 2 is the structural representation of retracting device; Fig. 3 is the structural representation of filter screen.Among the figure, 1-filter screen, 2-collecting-tank, 3-far-end node, 4-near-end node, 5-fixed pulley, 6-pull rope.
The specific embodiment
Below in conjunction with accompanying drawing the claimed technical scheme of the utility model is done and to be specified.
A kind of cooling tower filter described in the utility model, comprise filter screen 1 and retracting device, described filter screen 1 is suspended on the top of collecting-tank 2, filter screen 1 opposite side edge is provided with respectively far-end node 3 and near-end node 4, near-end node 4 is fixed on the distolateral wall of collecting-tank 2 offshores, described retracting device comprises the fixed pulley 5 that is fixed on the collecting-tank 2 far-end sidewalls, and pull rope 6 is housed on the fixed pulley 5, and an end of pull rope 6 connects filter screen far-end node 3.Filter screen is rectangle normally, but all standing collecting-tank, two angles of a rectangular side are the far-end node, and two angles of opposite side are the near-end node, and the far-end node links to each other by force with traction.
Realize that recirculated water filters entirely when guaranteeing the circulating water flow flux.Utilize the tiny filter screen of mesh that collecting-tank is carried out all standing, preferred screen specification is the 2.5-100 order.
Concrete use procedure is: filter screen 1 near-end node 4 is fixed on the distolateral wall of collecting-tank 2 offshores, and far-end node 3 is fixed on the far-end sidewall of collecting-tank 2 opposite sides by the retracting device that is made of pull rope 6 and fixed pulley 5.Recirculated water falls into collecting-tank 2 by cooling tower top, and the filter screen 1 that comprehensively covers collecting-tank 2 tops filters out the solid impurity in the recirculated water, stays on the filter screen 1.After operation a period of time, along with the solid impurity on the filter screen 1 increases, utilize retracting device, after two far-end nodes 3 of filter screen 1 are moved to the offshore end and pack up and more finish changing filter screen, move 3 of two distal colorectal of filter screen 1 to the collecting-tank far-end by retracting device again and fix, reach the purpose of Hand scarf, replacing filter screen 1.
The utility model is not limited to above embodiment; to those skilled in the art; the utility model can have various modifications and variations; all within spirit of the present utility model and principle; any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
