Description

Cooling tower water Steam Recovery device

Technical field:

The utility model relates to the recycling device of a kind of cooling tower water Steam Recovery, exactly, is a kind of cooling tower water Steam Recovery device.

Background technology:

At present, behind the high temperature and high pressure steam condensing after thermal power plant's work done in wet cooling tower during with air heat exchange, can produce a large amount of water vapours, these water vapours have spilt into atmosphere together together with used heat, and great lot of water resources has wasted, both strengthened thermal power plant's water intaking burden, improve the recirculated water running expense, wasted a large amount of energy, increased change water burden again, increased change water medicament use amount, serious to ambient influnence.The water system air-condition cooling tower faces same water resource waste problem.

Summary of the invention:

The purpose of this utility model provide a kind of can the conserve water resource consumption, can reduce the water intaking expense again, change a kind of small investment, instant effect, the practicality that water rate uses, a kind of cooling tower water Steam Recovery device that helps improving environment.

The utility model is to realize by following technical solution: a kind of cooling tower water Steam Recovery device, be installed in cooling tower air outlet top, the lower end edge circumference of the Steam Recovery cover that has conical structure of this recover evenly is provided with can regulate air guide hole, the lower end of Steam Recovery cover is an air intake, around being provided with its inwall that to regulate the air guide hole place, a plurality of fixedly wind deflectors and tunable wind-guiding plate are housed respectively, the upper end of Steam Recovery cover links to each other with an end of steam transmitting pipe, the frequency conversion axial flow blower is housed in the steam transmitting pipe of this end, the steam transmitting pipe other end with go out vapour cover upper end and link to each other, go out vapour cover lower end and be welded with steel plate, be evenly distributed with through hole on the steel plate, be welded with steam outlet pipe in each through hole, check plate is equipped with in the lower end of every steam outlet pipe, goes out vapour cover and steam pipe and packs in the steam dissolving container.

One side of described steam dissolving container is equipped with gap, and gap is higher than the steam outlet pipe venthole.

The obtained effect of the utility model is as follows: the utility model is at power plants wet cooling tower, the serious present situation of water system central air-conditioning cooling water evaporation loss, utilize cooling tower water Steam Recovery device, the water vapour that a large amount of evaporation losses cause is assembled by reclaiming cover, utilize the frequency conversion axial flow blower to form elevated pressures, inject the molten carbonated drink of steam dissolving container, realize the recycling of water vapour.This Steam Recovery device is simple in structure, easy to install, cost is low, can improve environment again, is particularly suitable for the renovation and utilization of power plants wet cooling tower.According to thermal power plant's wet cooling tower operation conditions measuring and calculating, this Steam Recovery device can make existing cooling tower evaporation loss sharply reduce, water saving about 60%, and economized cycle water power consumption about 5% in addition, can also be saved a large amount of change water medicaments.Add up according to interrelated data, the end of the year 2004,3.5 hundred million kilowatts of the existing thermoelectricity installed capacitys of China, about 6,000,000,000 cubes of water consumptions, if adopt this device all to recycle, then can economize on water about 3,600,000,000 cubes, be equivalent to 7.58% of National urban water supply total amount in 2003, the industry, the domestic water that convert and can satisfy 1,700 ten thousand urban populations can be alleviated thermoelectricity and contradiction that the people strive water greatly.If water system air-condition cooling tower liquid is transformed, the water resource that saves is just more considerable, therefore, has application value widely.

Description of drawings:

Fig. 1 is the structural representation of cooling tower water Steam Recovery device;

Fig. 2 is that the A of Fig. 1 is to view;

Fig. 3 is that the B of Fig. 1 is to view;

Fig. 4 is equipped with the schematic diagram of check plate for the steam outlet pipe of cooling tower water Steam Recovery device.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Fig. 1,2,3,4, the utility model is installed in cooling tower air outlet top, cooperates with the cooling tower air outlet, assembles water vapour.The lower end edge circumference that has the Steam Recovery cover 2 of conical structure of the present utility model evenly is provided with can regulate air guide hole 1, the lower end of Steam Recovery cover 2 is an air intake 9, around being provided with its inwall that to regulate air guide hole 1 place, a plurality of fixedly wind deflectors 12 and tunable wind-guiding plate 11 are housed respectively, the upper end of Steam Recovery cover 2 links to each other with an end of steam transmitting pipe 4, in the steam transmitting pipe 4 of this end frequency conversion axial flow blower 3 is housed, the other end of steam transmitting pipe 4 links to each other with the upper end that goes out vapour cover 5, go out vapour cover (5) lower end and be welded with steel plate (14), steel plate is evenly distributed with through hole on (14), be welded with steam outlet pipe (8) in each through hole, check plate 13 is equipped with in the lower end of every steam outlet pipe 8, going out vapour cover 5 and steam pipe 8 packs in the steam dissolving container 6, one side of steam dissolving container 6 is equipped with gap 7, and gap 7 is higher than steam outlet pipe 8 ventholes.

The water vapour that the utility model utilizes Steam Recovery cover 2 that the cooling tower mouth is come out gathers one, under the effect of frequency conversion axial flow blower 3, form negative high voltage, with water vapour from air intake 9 suction and form high steam stream, high steam stream is transported to out in the vapour cover 5 by steam transmitting pipe 4, go out and be furnished with many steam outlet pipes 8 in the vapour cover 5, because steam outlet pipe 8 is distributed in the steam dissolving container 6, water vapour is injected in the steam dissolving container 6 that is marked with molten carbonated drink in advance by steam outlet pipe 8, water in the steam dissolving container 6 infinitely absorbs water vapour, water vapour becomes the aqueous water that can recycle after dissolving in molten carbonated drink, therefore molten vapour-liquid face 10 raises, the aqueous water of returning is derived through gap 7, thereby realizes the recycling of cooling tower water steam.

Be provided with air guide hole 1 in Steam Recovery cover of the present utility model 2 lower ends, to keep the normal pressure reduction of cooling tower.Tunable wind-guiding plate 11 in the air guide hole 1 is according to the size adjustment of extraneous wind speed and the fixing gap between the wind deflector 12, thereby regulate the caliber size of air guide hole 1, improve the negative high voltage that frequency conversion axial flow blower 3 places form with the extraneous wind speed of effective utilization, be beneficial to improve steam pump drainage efficient.

In steam outlet pipe of the present utility model 8 exits, be provided with the check plate 13 that under water vapor pressure, to open automatically, under molten carbonated drink pressure, close, with prevent water steam dissolve in molten carbonated drink after molten carbonated drink pour in down a chimney back in the steam outlet pipe 8, reduce water vapour and enter the resistance of molten carbonated drink, improve admission efficient by steam outlet pipe 8.
