Abstract
The utility model discloses a cooling tower steam recovery system which is installed in a cooling tower air duct below a fan and above a dehydrator. An air suction hood of built-in guide fan blades is connected with a guide duct, the guide duct is connected with a steam inlet of a steam-water separator after penetrating through the air duct, and a steam outlet of the steam-water separator is connected with an air inlet of an axial fan through the guide duct. Recovered water is discharged into a cooling tower water storage tank through a water discharge pipe connected with the water outlet of the steam-water separator, and residual gas is discharged through a gas outlet of the axial fan. The cooling tower steam recovery system disclosed by the utility model does not change the appearance of the cooling tower or lowering the original heat dissipation capacity of the cooling tower, is convenient for mounting and construction and easy for computation, and has high recovered water quantity.
Description
Technical field:
The utility model relates to a kind of circulating water cooling tower technical field, says exactly, is a kind of cooling tower water vapor recovery recycling system.
Background technology:
At present, in petroleum chemical enterprise, industrial circulating water cooling system open type force ventilation wet-type countercurrent cooling tower commonly used carries out circulating water, the force ventilation wet-type countercurrent cooling tower generally adopts the air-draft-type cooling tower, many towers connect in a row, every tower quadrate or rectangle, hot water enters cooling tower by upper hose, by slot type or tubular type water distribution system, make hot water reticulate and be uniformly distributed along the tower plane, then by nozzle, hot water is sprayed onto on filler, through filler Cheng Yuzhuan, by air, distributes district to fall into pond at the bottom of tower.Air enters in tower from air inlet, through the rain belt under filler, with hot water, becomes rightabout (adverse current) through filler, by water collection device, air exhauster, from air duct, discharges.These steam together enter atmosphere together with used heat, according to the cooling tower Thermodynamics Formulas, calculate, and the evaporation capacity of cooling tower water is quantity of circulating water 1.6%, 80% left and right that generally accounts for rate of water make-up.Not only great lot of water resources is wasted, but also has increased the use amount of chemical agent, reaches the many environmental problems such as visual pollution that cause owing to producing a large amount of water smoke.
Summary of the invention:
The purpose of this utility model is to provide a kind of and does not change the cooling tower outward appearance, do not reduce the former heat dissipation capacity of cooling tower, installation is easy, it is large and be easy to the cooling tower water vapor recovery recycling system of calculating to reclaim the water yield.
For achieving the above object, the utility model is realized by following technical solution: a kind of cooling tower water vapor recovery recycling system is arranged in the cooling tower air duct dehydrater top, flabellum below.Air-suction cover by built-in wind-guiding flabellum is connected with guide duct, and guide duct is connected from passing with the steam-water separator air intake in air duct, and the steam-water separator venthole is connected with the axial flow blower air inlet by guide duct.Recycle-water enters the cooling tower cistern by the drainpipe be connected with the steam-water separator delivery port, and residual air is discharged by the axial flow blower gas outlet.
Operation principle of the present utility model is: axial flow blower forms higher negative pressure after opening in air-suction cover, steam forms by the wind-guiding flabellum in air-suction cover the nowed forming that the eddy current type rotation is risen, along with strengthening negative pressure in eddy current, the eddy current flow velocity increases radially all the increasing with the core radius of tangential component and eddy current of fluid velocity.Along with the increase of shear stress and swirl ratio, it is more rapid that eddy current becomes.When touching filler, eddy current produces swift current stream.The ascending water steam air-flow that is greater than air-suction cover area of plane several times can be condensed thus in air-suction cover and import steam-water separator by guide duct, steam is condensed after by guide duct and steam-water separator and is decomposed into distilled water and residual air, distilled water enters the cooling tower cistern by discharge outlet, and residual air enters atmosphere by the axial flow blower exhaust outlet.
The obtained effect of the utility model is as follows: the utility model loses serious present situation for China's industrial circulating water wet cooling tower cooling water evaporation, by utilizing this cooling tower water vapor recovery recycling system, has effectively realized the recycling of steam.This cooling tower water vapor recovery recycling system does not change the cooling tower outward appearance, does not reduce the former heat dissipation capacity of cooling tower, installation is easy, it is large and be easy to calculate to reclaim the water yield, is specially adapted to the transformation of China's industrial cycle water cooling tower.According to the report of national water-using sector, national cooling tower evaporation water consumption accounts for the 60-70% of water for industrial use, and the annual water consumption is greatly about 15,000,000,000 cubes.The cooling tower systems in the whole nation will reclaim 12,000,000,000 tons of high-quality distilled water for country every year, be equivalent to the year available water of project of South-to-North water diversion.Therefore, carry out the recycling of cooling tower steam water, economize on water significant, to energy-saving and emission-reduction, the contribution of developing a circular economy is huge.
The accompanying drawing explanation:
The structural representation that Fig. 1 is cooling tower water vapor recovery recycling system;
The A that Fig. 2 is Fig. 1 is to view
The B that Fig. 3 is Fig. 1 is to view
The specific embodiment:
Below in conjunction with accompanying drawing in detail the utility model is described in detail: as shown in Figure 1, 2, 3, cooling tower water vapor recovery recycling system, be arranged in the cooling tower air duct, dehydrater top, flabellum below.Air-suction cover 1 by built-in wind-guiding flabellum 6 is connected with guide duct 2, and guide duct is connected from passing with steam-water separator 3 air intakes in air duct, and the steam-water separator venthole is connected with axial flow blower 4 air inlets by guide duct.Recycle-water enters the cooling tower cistern by the drainpipe 5 be connected with the steam-water separator delivery port, and residual air is discharged by the axial flow blower gas outlet.
