Abstract
The utility model discloses an evaporation type condensation cooler which comprises a water collecting trough, and a heat-exchange coil pipe, a spray thrower, a drift eliminator and a draught fan which are arranged above the water collecting trough orderly, wherein, an atomizer is arranged between the heat-exchange coil pipe and the water collecting trough, and air guiding grids are arranged on the ring wall of an outer casing between the atomizer and the water collecting trough. The heat-exchange coil pipe adopts a corrugated coil pipe so as to have deforming capacity under heat stress, a water level controller is arranged at the outer side of the water collecting trough to control the water level in the water collecting trough, and a draining opening is arranged at the bottom of the water collecting trough. Because the heat-exchange coil pipe can generate axial telescopic deformation, formed scale is easy to crack and fall. A filler layer is replaced by the atomizer so that the air flow resistance in the system is reduced, the air volume is increased, and the vapour-water ratio is improved. By increasing the contact time and the contact area of the air and cooling water, the atomizer can carry off hidden heat rapidly and improves the heat-exchange effectiveness, retarding the growing speed of the scale crust on the surface of the heat-exchange coil pipe.
Description
Technical field
The utility model relates to a kind of heat transmission equipment, specifically relates to a kind of evaporating heat exchanger that is used for fluid.
Background technology
At present in the industrial production field, especially evaporative condenser is all adopted in related fluid heat exchange in chemical process, this heat transmission equipment consists predominantly of heat exchange coil, spray equipment, water collection device, its bottom is provided with water tank, the outside is provided with water circulating pump and blower fan, cooling water during work in the water tank is pumped into spray equipment, spray equably on the heat exchange coil surface, cooling water part behind the absorption heat is evaporated to water vapour, all the other fillers and go into water tank of then flowing through with air heat exchange cooling is laggard, and then repeat this circulation and keep normal industrial production.Yet in the equipment continuous evaporation along with cooling water in service, concentrated,, cause the heat exchange coil thermal resistance to increase, cause heat exchange efficiency to reduce, increased the hidden danger of energy consumption and equipment at heat exchange coil surface appearance scale formation in various degree; In addition since in the filler from the influence of dust in the atmosphere and dirt, often cause filler to stop up, thereby need regularly clean equipment, increased the maintenance workload of equipment, influenced ordinary production and equipment normally moves.Filler generally adopts the PVC material to make in addition, because its aging, distortion and broken and then form phenomenons such as bridging, channel, and the filler fragment badly influences the effect of cold water to the obstruction of equipment and pipeline, cause equipment can not be continuously, high loaded process.
Summary of the invention
At the problem that prior art exists, the utility model provides a kind of improved evaporating type condensing cooler, and it can make heat transmission equipment realize operation steady in a long-term, and has characteristics such as heat exchanger effectiveness height, heat exchange coil be less scaling.
The purpose of this utility model is achieved in that
This evaporating type condensing cooler comprises water leg and is located at heat exchange coil, spray thrower, water collection device and the blower fan on water leg top successively, between heat exchange coil and water leg, be provided with atomizer, the water inlet end of spray thrower and atomizer is connected with water pump between the water leg delivery port, and the shell body ring wall between atomizer and water leg is provided with wind-guiding grate.
Above-mentioned heat exchange coil adopts the corrugated coil pipe, so that it has the ability of axial deformation under thermal stress.One water level controller is set on the above-mentioned water leg, and in order to the water level in the control water leg, the water leg bottom is provided with sewage draining exit.
The technological progress that the utility model is obtained:
1. because adopting, heat exchange coil has thermal stress compensation effect corrugated coil pipe, in work,, action of thermal difference produces certain axial stretching distortion owing to can making it, thereby make incrustation scale that bellows surface forms cracking and coming off in the bellows distortion, make corrugated pipe coil have the ability of automatic desludging; Improved the operating force-bearing situation of equipment on the other hand, reduced junctions such as tube bank, housing and tube sheet because the possibility that thermal (temperature difference) stress damages has improved the equipment operational reliability.
2. because the utility model changes packing layer of the prior art into atomizer between heat exchange coil and water leg, thereby make that air flow resistance reduces in the system, air quantity increases (compared with prior art increasing 20%～30%), thereby has improved steam-water ratio; This atomizer can be at the droplet that under the lower pressure 0.014KPa water is sprayed into about diameter 0.4cm in addition, this droplet is fallen after rising, the time of contact and the contact area of air and cooling water have been strengthened, guaranteed the exchange heat of empty G﹠W, can take latent heat in the cooling water and sensible heat out of system rapidly, improve the heat exchanger effectiveness of spray at the water on heat exchange coil surface; Shower water washs fully to the air that enters from wind-guiding grate simultaneously, below heat exchange coil, utilizes gravity to carry out sedimentation in water leg most dust interceptions, has delayed the growth rate of heat exchange coil surface dirt layer.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is provided with an atomizer 5 between heat exchange coil 4 and water leg 6, heat exchange coil 4 adopts corrugated stainless steel, to increase heat exchange area, change the flow regime of tube fluid, simultaneously the corrugated coil pipe can produce the axial stretching distortion under thermal stress, thereby the incrustation scale that forms on its surface is easy to crack and come off, and has improved the heat exchange effect; Cooling water is pumped into spray thrower 3 and atomizer 5 through water leg 6 respectively by water pump 7, and this spray thrower 3 is made up of shower and the shower nozzle of being located on the shower, and atomizer 5 is made up of shower and the atomizer of being located on the shower; Be disposed with water collection device 2 and blower fan 1 on the top of spray thrower 3; Shell body ring wall between atomizer 5 and the water leg 6 is provided with wind-guiding grate 12, enters heat-exchange system effectively to stop foreign material, at water leg 6 arranged outside one water level controller 10, and establishes a sewage draining exit 11 in water leg 6 bottoms.
The course of work of the present utility model is: cooling water is pumped to spray thrower 3 by water pump 7 one tunnel, the cooling water of its ejection sprays at the outer surface of heat exchange coil 4 equably and forms water membrane, high-temperature medium enters from the upper inlet 8 of heat exchange coil 4, flowed out by the lower part outlet 9 of the cryogenic media of cooling cooling or condensation from heat exchange coil 4, after condensed water absorbs the heat of high-temperature medium, part evaporation, by blower fan 1 discharge system, fall into water leg 6 after the air heat exchange of remainder and the forced convertion cooling by water collection device 2 backs; Another road cooling water that is pumped by water pump 7 is via the atomizer ejection of atomizer 5, the air that is entered by wind-guiding grate 12 cools off, blower fan 1 forces air to pass through atomizer 5 and heat exchange coil 4 with the speed of 3～5m/s simultaneously, make the water droplet of atomizer ejection form certain delay aloft, promote the evaporation of moisture film simultaneously, the heat release of enhanced heat exchange coil pipe 4., be located at water leg 6 other water level controllers 10 automatic unlatchings and replenish cooling water because evaporating loss is crossed when hanging down the water level of header tank 6 when cooling water in the system.
