Abstract
The utility model discloses a closed air cooling system for auxiliary machine circulating cooling water. The closed air cooling system comprises a power plant desalted water system, an auxiliary machine circulating water pump, a cooling-needed auxiliary machine system, a spray water system and an evaporative cooling tower, wherein the spray water system comprises a spray water pump, a spray water pipeline connected with the spray water pump, and spray nozzles connected with the spray water pipeline; and a cooling water pipe column, a closed water inlet pipeline and a closed water outlet pipeline respectively connected with an inlet and an outlet of the cooling water pipe column are arranged in the evaporative cooling tower. The closed air cooling system provided by the utility model has the advantages that the consumption of fresh make-up water is reduced, the water-saving effect is obvious, water is basically not needed to be replenished as the auxiliary machine adopts a closed circulating water system, and the closed air cooling system provided by the utility model can save 40%-50% fresh water compared with the opened circulating water cooling system since spray water as a temperature adjusting means gradually reduces along with the reduced environment temperature and is not needed in winter, etc.
Description
Technical field
The utility model relates to a kind of recirculated cooling water air cooling system, particularly relates to a kind of subsidiary engine recirculated cooling water enclosed air cooling system.
Background technology
Conventional thermal power plant subsidiary engine cooling water adopts the open circulation cooling water system, the water quench subsidiary engine equipment of open circulation water system, and the open circulation cooling water after the intensification is to gravity-flow ventilation or induced cooling tower cooling.In the open circulation cooling water system, cooling water directly contacts with air, heat and mass exists simultaneously, so evaporation, wind and blowdown flow rate are big, water consumption is bigger, constantly evaporates owing to water simultaneously, solid content, calcium magnesium plasma concentration increase gradually in the water, and grow mushroom,, want dosing usually to keep the stable of water quality in order to reduce the foulant in the water.Owing to contain foulant, more easily be attached to the subsidiary engine equipment surface in the while water, reduce heat transfer efficiency, also suitable etching apparatus reduces the subsidiary engine service life of equipment.
The utility model content
The purpose of this utility model is to provide a kind of subsidiary engine recirculated cooling water enclosed air cooling system.
The purpose of this utility model is implemented by following technical scheme, a kind of subsidiary engine recirculated cooling water enclosed air cooling system, include power plant's DW system demineralized water system, the subsidiary engine water circulating pump, need the cooling auxiliary system, it also includes water-spray system and evaporative cooling tower, described water-spray system includes the spray water pump, shower water pipeline that is connected with described spray water pump and the nozzle that is connected with described shower water pipeline, be provided with the cooling water tube bank in the described evaporative cooling tower, the enclosed water inlet channel and the enclosed water outlet conduit that are connected respectively with the entrance and exit of described cooling water tube bank, described cooling water tube bank top is provided with blower fan, be provided with the nozzle that is connected with described shower water pipeline between described cooling water tube bank and the described blower fan, described cooling water tube bank below is provided with the air inlet grid, described air inlet grid below is provided with the shower water water leg, described enclosed water inlet channel is connected with the coolant outlet of described subsidiary engine water circulating pump, described enclosed water outlet conduit is connected with the described cooling water inlet of cooling auxiliary system that needs, and the described coolant outlet B of cooling auxiliary system that needs is connected with the cooling water inlet of described subsidiary engine water circulating pump.
Subsidiary engine cooling water and shower water adopt demineralized water; The subsidiary engine cooling water cools off in closed system, does not consume, and subsidiary engine cooling water heat major part is taken away by air, with a small amount of shower water temperature adjustment.
The cooling of evaporative cooling tower is a kind of air cooling and the clammy technology that combines, and two parts cooling principle is as follows:
(1) air cooling part: working fluid is in the cooling water of evaporative cooling tower tube bank circulation, and the fluid heat is cooled after the tube wall of festoon absorbs, and the temperature difference is big, and thermal resistance is also big.Form saturated warm steam with water and air, the blower fan by the top is outside the heat discharge machine of tube wall.
(2) clammy part: when temperature that fluid temperature (F.T.) surpass to be set, start spray system automatically, the spray water pump is sprayed at water on the tube wall of damp and hot cooling water tube bank and forms moisture film, absorbs a large amount of heats (evaporation latent heat) by evaporation.A shower water part becomes steam, is taken away by flow air, and the water droplet that is not evaporated drops in the shower water water leg for recycle next time.The closed circulation of fluid in the cooling water tube bank, no consumption amount in theory.The consumption of shower water also only is 0.35%～0.45% of a subsidiary engine recirculated cooling water.
Advantage of the present utility model is, (1) reduced the consumption of fresh supplemented water, water-saving result is remarkable, subsidiary engine recirculated water adopts closed system, does not need moisturizing substantially, and shower water is as the temperature adjustment means, reduction with environment temperature, reduce gradually, winter is out of service, compares with the open circulation cooling water system can save fresh water and be about 40%～50%; (2) improved subsidiary engine equipment heat transfer efficiency and life-span, because the closed circulation system employing is demineralized water, hardness is low, impurity is few, pH value 7～9, and alkalescence water does not contact with atmosphere, not contaminated, reduced subsidiary engine device structure and corrosion widely, improved subsidiary engine equipment heat transfer efficiency and life-span; (3) safeguard that simply recondition expense is low, comparing with the open circulation water system does not have filler in the tower, need not change, and has reduced the Maintenance and Repair expense.
