Description
Technical field
The present invention relates to a kind of novel closed cooling tower, be specifically related to a kind of at cooling tower middle part air intake, the mobile closed cooling tower of all realizing adverse current of fluid in tube bank and the filler in wind direction and the tower.
Background technology
Cooling tower mainly is directly to contact with shower water by air, finishes the equipment of exchange heat by the evaporative heat loss of shower water, is divided into open type cooling tower and closed cooling tower.For closed cooling tower, the fluid that is cooled flows in pipe, and shower water flows through the heat that the tube bank heat-transfer area is taken away tube fluid; Air contacts with shower water, takes away the heat of shower water by the shower water evaporation.Cooling tower divides crossing current tower and countercurrent tower again, and usually, crossing current tower air-flow direction is a horizontal direction, and the countercurrent tower air-flow direction is a vertical direction.Crossing current tower and countercurrent tower respectively have merits and demerits, and one of advantage of countercurrent tower is to participate in forming counter-current flow between the fluid of heat exchange, and bigger the heat and mass temperature difference or enthalpy difference can be arranged, and helps conducting heat.One of shortcoming of common countercurrent tower is that ventilation area is littler than the crossing current tower, thereby air mass flow is littler than the crossing current tower, is unfavorable for conducting heat.
For closed cooling tower, the form of crossing current tower is more, and the form of countercurrent tower is less.In present existing adverse current enclosed turriform formula, filler that has and tube bank interlaced arrangement, the filler that has is arranged apart with tube bank, but still there is the little shortcoming of above-mentioned ventilation area in great majority, in addition, the temperature difference of spray water and air, shower water and tube fluid is extremely inhomogeneous in flow process, has influenced heat transfer.At present existing indivedual enclosed towers are from the upper and lower air intake of tower, flow through tube bank and filler respectively, bigger ventilation area is arranged, but this tower packing partly is the crossing current form, than a little less than the heat-transfer effect of adverse current form some, and the top air inlet sucks the hot-air of cooling tower discharging easily, is unfavorable for heat exchange.
Summary of the invention
The objective of the invention is to disclose a kind of middle part air intake all adverse current closed type cooling column, the ventilation area that overcomes existing adverse current closed type cooling column existence is little, shortcomings such as the temperature difference of spray water and air, shower water and tube fluid is extremely inhomogeneous in flow process, and heat transfer efficiency is low.
Technical thought of the present invention is: arrange filler, lower disposed tube bank on the top of closed cooling tower, two sides at the cooling tower middle part are driven the air port into, air divides two-way after these two side air inlet mouths enter cooling tower, flow through filler on the road direction and discharge from the cooling tower top; Flow through tube bank under one road direction, upwards flow from air exhaust passage then, discharge from the cooling tower top; This air exhaust passage is positioned at two sides that cooling tower does not drive the air port into.In cooling tower, shower water flows from top to bottom, and the fluid that is cooled in the tube bank flows from bottom to top.Like this, in the tube bank air and shower water flow in the same way and with pipe in the be cooled counter-current flow that flows into of fluid, air becomes counter-current flow with shower water in the filler.This middle part of the present invention air intake, the full counter-current flow mode of two-way flow up and down, can increase the circulation area of air, reduce the possibility that air refluxes, increase between shower water and the fluid, the mean temperature difference or the enthalpy difference of the heat and mass between air and the shower water, thereby improve the heat and mass effect, reduce the tube bank area, reduce cost.
The middle part air intake all adverse current closed type cooling column, be characterized in: air is that the middle part from closed cooling tower enters, divide two-way to flow through filler arranged apart and tube bank respectively up and down then, the water of spray thrower ejection flows from top to bottom, the tube bank inner fluid flows from bottom to top, in the tube bank air and shower water flow in the same way and with pipe in the be cooled counter-current flow that flows into of fluid, air becomes counter-current flow with shower water in the filler.
The middle part air intake all adverse current closed type cooling column, it comprises: air outlet, blower fan, sparge pipe, spray thrower, filler, last air inlet, following air inlet, tube bank, water-collecting tray, water pump, pond formula injection well downhole flow regulator, air exhaust passage and channel partition, be characterized in: filler is arranged in the closed cooling tower upper area, tube bank is arranged in the lower area of cooling tower, blower fan is at the tower body top, and water-collecting tray is furnished with sparge pipe in the tower body bottom between blower fan and the filler, be connected with a plurality of spray throwers on the sparge pipe, be furnished with pond formula injection well downhole flow regulator between filler and tube bank, formula injection well downhole flow regulator bottom in pond has many apertures, and water-collecting tray is connected with sparge pipe through water pump; Respectively have air inlet and following air inlet at the middle part of two sides of cooling tower, two sides and two channel partitions constitute two air exhaust passages in addition, air exhaust passage is communicated with the tower body lower area of arranging tube bank by the bottom of channel partition, is used for the air that discharge currents is crossed tube bank.
The middle part air intake that the present invention middle part air intake all adverse current closed type cooling column is taked, the method for two-way flow up and down, can increase the circulation area of air, reduce the possibility that air refluxes, increase between shower water and the fluid, the mean temperature difference or the enthalpy difference of the heat and mass between air and the shower water, thereby improve the heat and mass effect, reduce the tube bank area, reduce cost.
