Abstract
The utility model relates to a winter anti-freezing device for a closed cooling tower. A pipeline positioned on the water outlet end of a water inlet main valve (1) of the closed cooling tower is connected with an air inlet pipe (2) and a water discharge pipe (3), the inlet end of the air inlet pipe (2) is connected with a compressed air source through an air inlet valve (4), and the water discharge pipe (3) is connected with a sewage tank (6) through a water discharge valve (5); a pipeline positioned on the water inlet end of a closed cooling tower wet return main valve (7) is connected with a sewage discharge pipe (8), and the sewage discharge pipe (8) is connected with the sewage tank (6) through a sewage discharge valve (9). The anti-freezing device disclosed by the utility model prevents the closed cooling tower from frozen injury by additionally arranging an air purge device and removing accumulated water inside the pipelines and the accumulated water inside a radiating copper pipe especially by utilizing air impact and meets the requirement for intermittent operation of a system.
Description
Technical field
The utility model relates to a kind of closed cooling tower frost-resisting device.
Background technology
Closed cooling tower (being also evaporating air cooler or closed cooling tower) is that pipe heat exchanger is placed in tower, the heat exchange assurance cooling-down effect of air, shower water and recirculated water by circulation.The feature of closed cooling tower maximum is that the cooling water of avoiding nature to require high cleanliness pollutes, saving water resource.But closed cooling tower is in service because environment temperature is very low in the winter time, in the time of water system intermittent duty, be very easy to freeze injury occurs, use pure water medium in addition, more easily freeze, cause the heat dissipation copper pipe of cooling tower to break, cannot normally work.
Summary of the invention
The technical problem that the utility model solves: design a kind of closed cooling tower frost-resisting device, increase air purge set, utilize the impact of gas to remove the ponding in the ponding, particularly heat dissipation copper pipe in pipeline, prevent closed cooling tower generation freeze injury, meet the requirement of system intermittent duty.
Mentality of designing of the present utility model: deionized water cooling system is for avoiding nature to pollute water quality, system adopts enclosed circulation, wherein select closed cooling tower as heat abstractor, the hot water of system is supplied water to cooling tower by circulating pump, hot water is by the copper tubular heat exchanger heat radiation of sealing in cooling tower, in order to strengthen in radiating efficiency tower, copper pipe radiator top is also designed with spray equipment and ventilation blower adds strong convection, thereby reaches the object to hot water cooling.In the time that water pump is out of service, in pipeline, check valve is closed simultaneously, and in copper pipe radiator pipeline, water cannot be discharged completely, and because higher its freezing point of purity of water is lower, the phenomenon of therefore freezing in the winter time very easily occurs., there is approximately 70,000 yuan of freeze injury maintenance total costs in approximately 450,000 yuan of closed cooling tower costs, affects production line simultaneously and cannot drive to produce, and economic loss is huge.
Technical solution of the present utility model is: a kind of closed cooling tower frost-resisting device, on the pipeline of closed cooling tower water inlet main valve water side, connect an air inlet pipe and a drainpipe, and the arrival end of air inlet pipe is connected with compressed air gas source by intake valve, drainpipe is connected with foul water tank by draining valve; On closed cooling tower backwater main valve water inlet end pipeline, connect a blow-off pipe, and blow-off pipe is connected with foul water tank by blowoff valve.
Described air inlet pipe is positioned at into the peak place of water main valve water side pipeline with the joint of water inlet main valve water side pipeline, described drainpipe be connected to joint under.
Advantage of the present utility model and effect are: with low cost, simple to operate, and can meet system intermittent duty requirement, operational effect is good, has eliminated freeze injury, has improved the effective rate of utilization of equipment, saving water resource.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing 1 and the specific embodiment, the utility model is described in further detail.
A kind of closed cooling tower frost-resisting device, on its closed cooling tower water inlet main valve 1 water side pipeline, connect an air inlet pipe 2 and a drainpipe 3, and the arrival end of air inlet pipe 2 is connected with compressed air gas source by intake valve 4, and drainpipe 3 is connected with foul water tank 6 by draining valve 5; On closed cooling tower backwater main valve 7 water inlet end pipelines, connect a blow-off pipe 8, and blow-off pipe 8 is connected with foul water tank 6 by blowoff valve 9.Described air inlet pipe 2 is positioned at into the peak place of water main valve 1 water side pipeline with the joint of water inlet main valve 1 water side pipeline, described drainpipe 3 be connected to joint under.
Operation principle: in the time of system shutdown, close into water main valve 1 and backwater main valve 7, open the blowoff valve 9 on water return pipeline; Open compressed air inlet valve 4, for several times to the Hand-operated butterfly valve switch in closed cooling tower, the ponding that utilizes compressed-air actuated impact to remove in the ponding, particularly heat dissipation copper pipe in pipeline is discharged from blowoff valve 9 simultaneously; Close intake valve 4, open residual accumulated water in draining valve 5, backwater main valve 7 emptying pipes, realized the full discharge of closed cooling tower interior conduit ponding, prevent closed cooling tower generation freeze injury, meet the requirement of system intermittent duty.
