Abstract
The utility model provides a cooling tower injector with negative pressure. The cooling tower injector comprises a water injecting pipe, a nozzle is mounted on one end portion of the water injecting pipe, and the other end portion of the water injecting pipe is communicated with a water distribution pipe. The cooling tower injector is characterized in that a negative pressure water distribution tank is further communicated between the water injecting pipe and the water distribution pipe, and a negative pressure pipe is further communicated between the negative pressure water distribution tank and the water distribution pipe. By additionally arranging the negative pressure water distribution tank, when work of the injector is finished, negative pressure is generated in the negative pressure water distribution tank to fully suck remaining water in the nozzle and the water injecting pipe into the water distribution pipe, so that the problem of blockage of the nozzle due to icing of the remaining water in the nozzle and the water injecting pipe is solved.

Background technology
Injector is to utilize fluid to come the vacuum of the quality of transferring energy to obtain device, adopts the current that certain pressure is arranged by the nozzle ejection of the certain skew back degree of symmetrical uniform one-tenth, is aggregated on a focus.Use injector in cooling tower cooling water is sprayed onto on the packing layer of cooling tower, thereby extended the cooling water time of staying, increase heat exchange area and heat exchange amount, reach the purpose of cooling.Injector generally includes sparge pipe and is arranged on the nozzle of sparge pipe one end, water in water distribution system sprays in nozzle by sparge pipe, this injector all can residual a small amount of moisture in use finishing rear nozzle, in sparge pipe, this residual moisture easily freezes winter, two ice cubes very easily stop up the very little nozzle in aperture, cause the first step before using next time must remove ice cube, recover the function that sprays of nozzle, bring very large trouble to the use of injector, waste time and energy simultaneously.
Summary of the invention
In order to solve the deficiency in background technology, the purpose of this utility model is to overcome the defect of background technology, a kind of injector of the cooling tower with negative pressure is provided, by negative pressure, the residual moisture in nozzle and sparge pipe is drawn in sparge pipe, freezes and the problem of plug nozzle thereby solved nozzle and sparge pipe internal cause residual water.
For achieving the above object, the technical solution adopted in the utility model is: a kind of injector of the cooling tower with negative pressure, comprise sparge pipe, one end of described sparge pipe is equipped with nozzle, the other end of described sparge pipe is communicated with sparge pipe, it is characterized in that: also be communicated with a negative pressure distribution channel between described sparge pipe and described sparge pipe, between described negative pressure distribution channel and described sparge pipe, also be communicated with a negative tube.
In preferred embodiment of the utility model, further comprise that the bottom land of described negative pressure distribution channel is provided with the first opening, the second opening, described negative tube is communicated with described negative pressure distribution channel by the first opening.
In preferred embodiment of the utility model, further comprise that described negative tube is provided with the first control valve near described the first opening part.
In preferred embodiment of the utility model, further comprise that described sparge pipe is communicated with described negative pressure distribution channel by described the second opening, described sparge pipe is provided with the second control valve near described the second opening part.
In preferred embodiment of the utility model, further comprise that described the first control valve, the second control valve are connected with the first controller, second controller respectively, the duty of described the first controller, second controller is contrary.
In preferred embodiment of the utility model, further comprise that described negative pressure distribution channel is enclosed and formed by one of them of corrosion resistant plate, glass epoxy, titanium steel plate.
Usefulness of the present utility model is: a kind of injector of the cooling tower with negative pressure of the present utility model, by set up the negative pressure distribution channel between sparge pipe and sparge pipe, control when the injector end-of-job and open the first control valve, close the second control valve, the negative pressure formed in the negative pressure distribution channel is drawn into water residual in nozzle and sparge pipe in sparge pipe, thereby solved nozzle and sparge pipe internal cause residual water, freezes and the problem of plug nozzle.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of injector of the cooling tower with negative pressure of the present utility model.
In figure: 2, sparge pipe, 4, nozzle, 6, sparge pipe, 8, the negative pressure distribution channel, 10, negative tube, the 12, first opening, the 14, second opening, the 16, first control valve, the 18, second control valve, the 20, first controller, 22, second controller.
The specific embodiment
In order to make those skilled in the art person understand better the utility model scheme, and above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of injector of the cooling tower with negative pressure, comprise sparge pipe 2, one end of sparge pipe 2 is equipped with nozzle 4, the other end of sparge pipe 2 is communicated with sparge pipe 6, its special feature is between sparge pipe 2 and sparge pipe 6 also to be communicated with a negative pressure distribution channel 8, also is communicated with a negative tube 10 between negative pressure distribution channel 8 and sparge pipe 6.By between sparge pipe 2 and sparge pipe 6, setting up negative pressure distribution channel 8, when the injector end-of-job, negative pressure is drawn into the residual moisture in nozzle 4 and sparge pipe 2 in sparge pipe 6, has solved the problem because of the residual water plug nozzle.
Specifically be achieved in that the bottom land at negative pressure distribution channel 8 is provided with the first opening 12 and the second opening 14, one end of negative tube 10 is communicated with negative pressure distribution channel 8 by the first opening 12, the other end is communicated with sparge pipe 6, be provided with the first control valve 16 near the first opening 12 places on negative tube 10, and an end of sparge pipe 6 is communicated with negative pressure distribution channel 8 by the second opening 14, be provided with the second control valve 18 6 near the second opening 14 places on sparge pipe, the first control valve 16, the second control valve 18 also respectively with the first controller 20, second controller connects 22, and the first controller 20, the duty of second controller 22 is contrary, the result that two controllers are controlled is: when the first control valve 16 is opened, the second control valve 18 is closed, when otherwise the first control valve 16 is closed, the second control valve 18 is opened, both only open one of them at one time, specifically when injector is worked, open the second control valve 18, close the first control valve 16, water in water distribution system first fills up negative pressure distribution channel 8, through sparge pipe 2, from nozzle 4, spray again, when injector cuts out, open the first control valve 16, close the second control valve 18, water in negative pressure distribution channel 8 is back in sparge pipe 6 through negative tube 10 on the one hand, form negative pressure in whole groove after the backflow of moisture in negative pressure distribution channel 8 on the other hand, the negative pressure produced all is drawn into nozzle 4 and the interior residual moisture of sparge pipe 2 in sparge pipe 6, make in nozzle 4 and sparge pipe 2 and no longer include moisture entrapment, thereby solved the problem because of the icing plug nozzle of residual water.
