Description
Technical field
The utility model relates to a kind of novel closed cooling tower, is specifically related to a kind of middle part air intake, filler and the mobile closed cooling tower of all realizing adverse current of restraining fluid in layout, filler and the tube bank respectively.
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 tube bank takes away the tube fluid heat, and 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 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.
The utility model content
The purpose of this utility model is a kind of middle part of design air intake 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.
Whole thinking of the present utility model is a kind of middle part of design air intake adverse current closed type cooling column, 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 one road direction and discharge, flow through tube bank under the road direction, upwards flow from air exhaust passage then from the cooling tower top, discharge from the cooling tower top, this air exhaust passage is positioned at two sides not driving 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, the counter-current flow that flows into of the fluid that is cooled in the mobile and pipe of air and shower water in the tube bank, air becomes counter-current flow with shower water in the filler.This middle part of the present utility model 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.
A kind of middle part air intake 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.
Shower water is flowed from top to bottom by the spray thrower on the sparge pipe, and through pond formula injection well downhole flow regulator, the many apertures bottom the formula injection well downhole flow regulator of pond are flowed through and restrained water-collecting tray, enters through water pump to recycle after the top filler cools off again; Air divides two-way after two side air inlet mouths enter cooling tower, flow through filler on the road direction and discharge from the cooling tower top, flows through tube bank under the road direction, upwards flows from air exhaust passage then, discharges from the cooling tower top; In the tube bank air and shower water flow 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 that the utility model middle part air intake adverse current closed type cooling column is taked, the method for two-way flow up and down, and the upper and lower is arranged the structure of filler and tube bank respectively, can realize air and shower water concurrent in fluid countercurrent current in the filler, the tube bank and with the liquid form of tube fluid adverse current, help caloic and exchange.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.
