Abstract
The invention provides a crosswind utilized type cooling tower, and relates to a device for arranging and utilizing environmental crosswind of a power plant. The cooling tower comprises a general cooling tower body, a guide baffle mounted on the sidewall of the cooling tower, a guide crown mounted at an outlet of the cooling tower, and a side window mounted at the waist part or position above the waist part of the cooling tower body. According to the crosswind utilized type cooling tower, the environmental crosswind under a windward side flows through a guide channel consisting of the guide baffle and the sidewall of the cooling tower and is converted into updraft which upwards flows along the sidewall, and then the updraft is returned through the guide crown around the outlet of the cooling tower body to form an inclined updraft withstanding the incoming crosswind stream, so as to resist the direct interference of the environmental crosswind to the air stream from the outlet of the cooling tower body; meanwhile, the inclined updraft meets the incoming crosswind to further guide the hot air from the outlet of the cooling tower body; when the environmental crosswind is increased to reach a degree, a low pressure area of which the pressure is less than the pressure in the tower is formed in the side of the tower, the side window is opened at the same time to enable the updraft in the tower to flow out quickly, and as a result, the ventilating capacity of the cooling tower is improved.
Description
Technical field
The invention belongs to the industrial cooling fields such as generating, metallurgy, chemical industry, relate to a kind of circulating water equipment, particularly environment crosswind is carried out to the energy-saving safety gravity-flow ventilation cooling device of tissue utilization.
Background technology
Cooling tower is the key equipment of power plant indirect air cooling unit or closed cycle Water type cooling unit, is set up steam turbine vacuum, and by necessary condition that cold junction thermal source is taken away.But due to the existence of environment crosswind, and the uncontrollability of its direction and wind speed, all brings very large challenge to the economy of unit, safety, stable operation.
Environment crosswind mainly can destroy cooling tower inlet and outlet pressure field and flow field environment; vortex flow is formed in cooling tower inside; air flow deflector is there is at cooling tower; Outlet Section is caused to reduce; cold air is even caused to pour in down a chimney in tower; affect normal tower body natural ventilation rate, affect air cooling normal heat exchange.The domestic and international structure optimization to cooling tower at present mainly concentrates on cooling tower bottom air inlet mouth increases guiding device (as CN201320639660 etc.), cooling tower interior optimization filler (as CN201310631563 etc.), and cooling tower outlet increases (as CN201310745997 etc.) such as guiding devices, the research for cooling tower sidewall aspect is then relatively less.
Summary of the invention
The object of this invention is to provide a kind of crosswind and utilize cooling tower, to overcome the negative effect that environment crosswind produces cooling tower, and environment crosswind is converted into the resource that can effectively utilize, to improve the overall performance of cooling tower.Particular content of the present invention is as follows:
A kind of crosswind utilizes cooling tower, comprises conventional chilling tower (1) and diaphragm (4), it is characterized in that: install multiple diaphragm in the upper circumferential different angles of cooling tower sidewall (2).Described diaphragm is along cooling tower generatrix direction at right angle setting.Described diaphragm is evenly installed on the sidewall of cooling tower surrounding, or installs the side suffering strong wind in cooling tower for a long time concentratedly.Described diaphragm cross section can be designed to the shapes such as rectangle, trapezoidal or triangle.Described a kind of crosswind utilizes cooling tower, water conservancy diversion hat (3) can also be comprised, it is characterized in that: install a water conservancy diversion hat cooling tower outlet is peripheral, it is lower to being close to installation with cooling tower sidewall, its lateral surface replaces the cooling tower sidewall that is entirely covered and diaphragm to connect.Described water conservancy diversion hat (3) lateral surface bus is the straightway or curved section that open outside cooling tower.

A kind of crosswind utilizes cooling tower, and also can comprise conventional chilling tower, diaphragm, water conservancy diversion hat and side window, side window is installed on the cooling tower sidewall between diaphragm simultaneously.
beneficial effect
The present invention compared with prior art, have the following advantages and the technique effect of high-lighting: 1. when there is environment crosswind, the environment crosswind of horizontal direction enters the slot type flow-guiding channel that diaphragm and cooling tower side-wall outer side are formed in the windward side that wind direction and cooling tower side wall angle are greater than zero, because cooling tower belongs to the little curve tower of Di great Ding (as hyperbolic transmission tower) mostly, windward side environment crosswind is limited in flow-guiding channel and upwards flows along sidewall by diaphragm, guide further through water conservancy diversion hat again, formed upwards and with carry out flow path direction air-flow and have the air-flow obliquely of certain angle of attack, this air-flow can effectively stop cooling tower top ambient side wind cooling tower to be exported to the direct interference of upwards hot-air, the height in the protection effective plume district of cooling tower.
under lower wind conditions, after the environment crosswind of ascending air and incoming flow collects, formed with certain angle, Flow Velocity lower than the ascending air of cooling tower outlet air flow velocity, because the two relative velocity is less than the relative velocity without thermal updrafts under wind condition and surrounding air, reduce the adhesive attachment effect of surrounding air to thermal updrafts, contribute to the swabbing action improving cooling tower.
when environment crosswind reaches certain wind speed, the ascending air after collecting higher than thermal current speed adjacent in cooling tower outlet with certain angle, Flow Velocity, can carry out effective injection to thermal updrafts in tower, more strengthen its swabbing action.
the large space detour flow of environment crosswind to cooling tower tower body forms large negative pressuren zone in positions such as cooling tower sides, when environment crosswind reaches certain speed, negative pressuren zone air pressure is less than the heat air pressure of relevant position in tower, at this moment the non-return air door on this region side window is opened, hot-air can directly be sucked out from side window, improves the draught capacity of cooling tower.
