Description
Technical field
The utility model relates to industrial cooling device technical field, particularly relates to a kind of closed cooling tower.
Background technology
as everyone knows, cooling tower is a kind of cooling common apparatus, is widely used in chemical industry, quenching liquid (oil), iron and steel non-ferrous metal metallurgy, in Casting Equipment, hydraulic pressure, power equipment, power plant, central air-conditioning and many industry parts, it is mainly used in and is applied to water liquid, gas-liquid refrigeration project and toxic gas cooling, existing cooling tower comprises the main body with working chamber, the top of main body arranges opening, and be provided with blower fan at opening part, be disposed with from top to bottom spray equipment in the working chamber of main body, heat exchange layers, heat exchanger and water leg, be provided with air-inlet window on the outer wall of main body, water inlet and delivery port, zone in air-inlet window and main body between heat exchange layers and water leg communicates, the top of water leg is provided with water inlet, be communicated with on water leg and be provided with filling pipe, water leg communicates with extraneous water source by filling pipe, spray equipment communicates by shower with water leg, and be provided with spray pump on shower, be provided with heat exchanger tube in heat exchanger, heat exchanger tube communicates with the external world by water inlet and delivery port, the use principle of this cooling tower is by water inlet filling liquid in the heat exchanger tube, extraneous water source enters water leg by filling pipe, water in water leg is evacuated to spray equipment place and spray by spray pump, after the water at spray place waters to the heat exchange tube wall, carry out heat with liquid and transmit cooling, thereafter the water water inlet by the water leg top again enters in water leg and recycles, the heated gas that occurs in the spray heat transfer process forms saturated warm steam and discharges by blower fan, thereby whole formation is cooling, this cooling tower is in use found, heat exchanger tube in heat exchanger is pipe, and in pipe, flow rate of liquid is slower, thereby causes its course of work slow, and easily fouling under the heat exchanger tube pipe, dirt can't be processed, cooling capacity reduces, and reduce service life, and maintenance cost increases, and when the water in water leg is additional more at extraneous water source, can overflow in water leg to the working chamber of main body, cause damage of components, and the dirt in water leg can't be processed.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of flow rate of liquid very fast, less scaling, thereby has extended its service life, has reduced maintenance cost, and has effectively protected the parts that are cooled, convenient closed cooling tower of discharging dirt in water leg.
closed cooling tower of the present utility model, comprise the main body with working chamber, the top of described main body arranges opening, and be provided with blower fan at opening part, be disposed with from top to bottom spray equipment in the working chamber of described main body, heat exchange layers, heat exchanger and water leg, be provided with air-inlet window on the outer wall of main body, water inlet and delivery port, the top of water leg is provided with water inlet, be communicated with on water leg and be provided with filling pipe, spray equipment communicates by shower with water leg, and be provided with spray pump on shower, be provided with heat exchanger tube in heat exchanger, heat exchanger tube communicates with the external world by water inlet and delivery port, described heat exchanger tube is oval pipe, is provided with overfall above the outer wall of described water leg, is provided with sewage draining exit below the outer wall of described water leg.
Closed cooling tower of the present utility model also is provided with water collector in the working chamber of described main body, described water collector is positioned at the top of spray equipment.
Closed cooling tower of the present utility model, described blower fan are two groups.
Compared with prior art the beneficial effects of the utility model are: heat exchanger tube is set to oval pipe; be provided with overfall above the outer wall of water leg; be provided with sewage draining exit below the outer wall of water leg; like this; the pipe of ellipsoidal structure improves than the flow velocity of round tube; it is less scaling that flow velocity improves nature; thereby extended its service life; reduced maintenance cost; and overfall enters in working chamber in the time of can effectively having prevented the interior dilutional hyponatremia of water leg; effectively protected the parts that are cooled, dirt in water leg can be conveniently discharged in the design of sewage draining exit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
as Fig. 1, closed cooling tower of the present utility model, comprise the main body 1 with working chamber, the top of main body arranges opening, and be provided with blower fan 2 at opening part, be disposed with from top to bottom spray equipment 3 in the working chamber of main body, heat exchange layers, heat exchanger and water leg 5, be provided with air-inlet window on the outer wall of main body, water inlet 8 and delivery port 9, zone in air-inlet window and main body between heat exchange layers and water leg communicates, and be provided with water inlet at the top of water leg, be communicated with on water leg and be provided with filling pipe 6, water leg communicates with extraneous water source by filling pipe, spray equipment communicates by shower with water leg, and be provided with spray pump 7 on shower, be provided with heat exchanger tube 4 in heat exchanger, the external water inlet pipe of water inlet and delivery port and outlet pipe, can install electron detector at water inlet pipe, arrange according to temperature and carry out spray pump automatic switchover stall function, heat exchanger tube communicates with the external world by water inlet and delivery port, heat exchanger tube is oval pipe, be provided with overfall 10 above the outer wall of water leg, be provided with sewage draining exit 11 below the outer wall of water leg, like this, the pipe of ellipsoidal structure improves than the flow velocity of round tube, it is less scaling that flow velocity improves nature, thereby extended its service life, reduced maintenance cost, and overfall enters in working chamber can effectively prevent in water leg dilutional hyponatremia the time, effectively protected parts, dirt in water leg can be conveniently discharged in the design of sewage draining exit.
Closed cooling tower of the present utility model, also be provided with water collector 12 in the working chamber of main body, water collector is positioned at the top of spray equipment, like this, a part of water in gas after spray can be held back down, the water under holding back enters in water leg by gravity, has prevented that too much gas discharge from can cause the too moist problem of working environment, and effectively utilized water resource, prevented too much water resource waste.
