Abstract
The utility model provides an anti-freezing device for cross flow cooling tower, which is a new energy-saving anti-freezing device with novel structure and innovation design, the device can solve the problem efficiently that the cross flow cooling tower freezes in winter, and thus avoids the damage of tower body and dilapidation of the side-layer fillings in the tower caused by freezing. The utility model is realized by the following method: a plurality of cross flow hot water spraying branch pipe is arranged respectively on the top of each batten of louver at two sides of the air inlet of the cross flow cooling tower, the spraying branch pipes are connected in parallel with a spraying water supply tubes, the spraying water supply tubes are provided with a valve which are connected with the inlet water tube of cooling tower. The utility model is applicable for various type of cross flow cooling tower, especially for large-scale cross flow cooling tower, and is a new type anti-freezing device for cooling tower.
Description
Technical field
The utility model relates to a kind of cooling device, especially a kind of anti-icing equipment of cross flow cooling tower.
Background technology
Cross flow cooling tower is a cooling device commonly used in the industry such as oil, chemical industry, pharmacy, oil refining.In known technology, existing cross flow cooling tower mainly is by being fitted with blower fan, cooling filler in the cooling tower body, the air inlet of band shutter is housed in the both sides of tower body, the cold air that enters by air inlet is replaced with entering in the tower heat recirculated water, and is fitted with Your Majesty's water pipe and return pipe is formed on cooling tower.Limit by its structure, the severe cold area of existing cross flow cooling tower to the north of 45 ° of north latitude, winter operation has ice formation issues, mainly being that cooling tower both sides air inlet is icing shuts, the outer cold air of tower can't be replaced with heat recirculated water in the tower, cooling tower freezes and usually to cause the heavy damage of housing structure, and the boundary layer filler causes serious damage because of freezing in the tower, have in addition cause in the tower water temperature rising to exceed standard and influence cooling tower and normally move because freeze.And solve the cooling tower ice formation issues usually is that the method that adopts blower fan to turn round by force extracts in the outer cold air of tower and the tower heat recirculated water and replaces the requirement of satisfying the interior circulating water temperature of cooling tower, freeze and to take blower fan to reverse when serious to melt ice cube on the cooling tower, should consume a large amount of electric energy like this, the fault rate that has increased blower fan has again had a strong impact on the service life of blower fan.
Summary of the invention
In order to overcome the difficult problem that prior art exists, the utility model provides a kind of novel structure, and design innovation can effectively solve cross flow cooling tower freezed in winter problem, avoid saving the new-type anti-icing equipment of electric energy because of the icing housing structure that causes destroys, the interior boundary layer filler breakage of tower.
The technical scheme in the invention for solving the technical problem is: design adopts on the shutter of cross flow cooling tower air inlet both sides respectively each impeller top of corresponding shutter to install several horizontal heat water-spraying's arms, the spray arm is parallel to the spray feed pipe, the spray feed pipe is equipped with feed-water valve and is connected in cooling tower Your Majesty water pipe, the anti-icing equipment of the cross flow cooling tower that consists of.In the time of need using to winter, open the valve that the spray feed pipe connects cooling tower Your Majesty water pipe, the heat recirculated water that makes cooling tower Your Majesty water pipe enter cooling tower flows into the spray arm and spray hot water on louvered battens, all the time form one deck hot water film on the shutter surface of cooling tower air inlet, can prevent effectively that the cooling tower air inlet from freezing, guarantee that cooling tower safety normally moves.
Because technique scheme has been adopted in the utility model design, also show through testing result on trial for several times, it compared with prior art has novel structure, design innovation, can effectively prevent the cross flow cooling tower freezed in winter, avoid saving advantages such as electric energy because of the icing housing structure that causes destroys, the interior boundary layer filler breakage of tower, it is applicable to various cross flow cooling tower, especially large-scale cross flow cooling tower is a kind of novel cooling tower anti-icing equipment.
