Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with execution mode and accompanying drawing, the present invention is described in further details.At this, exemplary embodiment of the present invention and explanation thereof are used for explaining the present invention, but not as a limitation of the invention.
In the utility model embodiment, provide a kind of converter valve outer cooling system, as shown in Figure 1, the outer cooling system of this converter valve comprises: aerial cooler 101, is connected with converter valve 102, for the interior recirculated cooling water of cooling converter valve 102; Supply equipment 103, is connected with aerial cooler 101, for injecting cooling water to aerial cooler inside.
In the utility model embodiment, by the interior recirculated cooling water of the cooling converter valve of aerial cooler (this aerial cooler can be mechanical draft aerial cooler), interior recirculated cooling water is input in aerial cooler by circulating water pump, adopt supply equipment to the inner cooling water that injects of aerial cooler, can be marginally to the inner spray of aerial cooler cooling water, also can be to inject in large quantities cooling water, realize the temperature that reduces aerial cooler inner air in the mode of humidification, and then water cooling mode and cooling air mode are combined as a whole, carry out the interior recirculated cooling water of cooling converter valve, simultaneously, avoid cooling water to be directly sprayed onto on aerial cooler surface, impact the heat transfer effect of aerial cooler, increase the problem of operation workload, thereby contribute to improve the heat transfer effect of aerial cooler, reduce operation workload.
In the specific implementation, in order effectively to reduce the consumption of cooling water, realize water consumption and water spray effect are control effectively, in the present embodiment, above-mentioned supply equipment 103 comprises: nozzle, is connected with aqueduct, for the cooling water of aqueduct is ejected into aerial cooler inside.Effectively control the effect of water consumption and water spray by nozzle, can reduce the consumption of cooling water, if will spray again after cooling water atomization, can also further reduce water consumption.
In specific implementation process, in order to improve the effect of the air themperature that reduces aerial cooler inside, nozzle can be arranged between the shutter and tube bank of aerial cooler.Between the shutter of aerial cooler and tube bank, spray cooling water by nozzle, make the air that enters aerial cooler shutter before entering tube bank, contact with cooling water and carry out heat exchange, reduce the temperature of tube bank porch air, improve the effect that reduces the air themperature of aerial cooler inside, contributed to aerial cooler leaving water temperature to meet converter valve inlet temperature needs.
In the specific implementation, in order further to improve the effect of the air themperature that reduces aerial cooler inside, in the present embodiment, nozzle is atomizer, will after cooling water atomization, be ejected into aerial cooler inside.After being atomized into droplet by cooling water, be ejected into again aerial cooler inside, realize and made the air that enters by aerial cooler shutter entering before tube bank, carry out heat exchange with the droplet of atomization cooling water, when droplet vaporization, absorb a large amount of latent heats of vaporization, further improved the effect that reduces the air themperature of aerial cooler inside.
In specific implementation process, affect the heat transfer effect of aerial cooler in order to reduce cooling water, in the present embodiment, above-mentioned cooling water can be demineralized water.Cooling water, through mode of reverse osmosis processing, can not cause air cooler fin scale formation to occur, and avoids cooling water to be sprayed onto the easy fouling of fin behind aerial cooler surface, and cleaning difficulty, causes heat transfer effect poor, affects the problems such as aerial cooler useful life yet.
Before aerial cooler internal spray cooling water, in order to spray at any time neatly cooling water, in the present embodiment, as shown in Figure 2, supply equipment 103 also comprises: water storage tank 1031, be connected with nozzle by aqueduct, for example, for laying in cooling water,, can store cooling water with water storage tank, need to spray cooling water time, cooling water is ejected into aerial cooler inside by the nozzle that can connect by aqueduct at any time, can also be water storage tank 1031 moisturizings at any time.In order to reduce floor space, reservoir can buriedly be arranged under mechanical draft indirect air cooling tower, and aerial cooler is arranged on air cooling compressor.
In the specific implementation, can realize like this and adopt nozzle that cooling water is ejected into aerial cooler inside, as shown in Figure 2, supply equipment 103 also comprises: water pump 1032, is connected with water storage tank 1031, for the cooling water of water storage tank is transferred in aqueduct.In order to reduce floor space, above-mentioned water pump can adopt immersible pump, is arranged in reservoir.
In implementation process, in order to adapt to the application demand of different regions environment, in the present embodiment, in the situation that ambient temperature exceedes preset temperature, water pump 1032 is transferred to the cooling water in water storage tank in aqueduct.For example, when ambient temperature is during lower than design temperature, only need to move the cooling interior recirculated cooling water of aerial cooler, reach zero water consumption; In the time of summer high temperature, in the time that ambient temperature exceedes design temperature, spraying system starts automatically, after water pump 1032 boosts, by aqueduct, the cooling water in water storage tank is transferred in nozzle, start to aerial cooler internal spray cooling water, auxiliary air cooler carries out cooling to the interior recirculated cooling water of converter valve, realizes water cooling, air is cooled to integrated.Be applicable to the outer type of cooling of converter valve of high temperature water-deficient area, the simple deficiency that uses cooling air mode by can solve thermal extremes weather to aerial cooler internal spray water time.
In the utility model embodiment, by the interior recirculated cooling water of the cooling converter valve of aerial cooler, adopt supply equipment to the inner cooling water that injects of aerial cooler, reduce the temperature of aerial cooler inner air in the mode of humidification, realize water cooling mode and cooling air mode have been combined as a whole, carry out the interior recirculated cooling water of cooling converter valve, simultaneously, avoid water to be directly sprayed onto on aerial cooler surface, impact the heat transfer effect of aerial cooler, increase the problem of operation workload, thereby contribute to improve the heat transfer effect of aerial cooler, reduce operation workload.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the embodiment of the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
