Description
Technical Field
The utility model relates to the technical field of falling film evaporators, in particular to a corrugated pipe falling film condensation cooler.
Background
The heat exchanger is a main device for heat energy exchange, has wide application in the fields of pharmacy, food, chemical industry, sugar production, salt production, caustic soda and the like, and is used for adding steam from a first effect when concentrating liquid materials, flash steam of the first effect is used for heating a second effect, and the like, the temperature of each effect is gradually reduced, and the temperature of final flash steam is about 50 ℃; the current treatment method for the end effect flash steam is that circulating water is used as a heat carrier, and a large amount of heat of the end effect flash steam is emitted to the atmosphere through a cooling tower; therefore, the final-effect flash steam is not fully utilized, and energy waste is caused. In order to improve the energy utilization rate, the Chinese patent specification with the bulletin number of CN203999466U discloses a device for utilizing the heat energy of the final-effect flash steam of a corn steep liquor evaporator, which comprises a surface condenser, a first circulating water pump, a pipeline, a cooling tower, a plate heat exchanger, a high-level water tank, a starch airflow heat exchanger and a second circulating water pump; the heat energy utilization device for the final-effect flash steam of the corn steep liquor evaporator can recycle the final-effect flash steam of the heat exchanger, and improves the energy utilization rate. However, this heat energy utilization device has a disadvantage in that it requires a large-scale facility such as a cooling tower, which results in a large investment cost.
Disclosure of Invention
The utility model provides the corrugated pipe falling film condensation cooler with low investment cost aiming at the defects.
The utility model is realized in the following way: the corrugated pipe falling film condensation cooler comprises a shell, a first tube plate and a second tube plate which are arranged on the left side and the right side of the shell, a first steam guide seal head and a second steam guide seal head, wherein the first tube plate and the second tube plate are fixedly connected with corrugated heat exchange tubes; the lower part of the inner cavity of the shell is provided with a filler; a water receiving basin is arranged below the shell, a liquid inlet is arranged on the water receiving basin, a water outlet at the bottom of the water receiving basin is connected with a circulating water pipe with a water pump, and the upper end of the circulating water pipe is connected with an inlet at the right end of the film distributor
By adopting the structure, during operation, the cooling liquid (material) enters the water receiving disc through the liquid inlet, the cooling liquid in the water receiving disc is conveyed into the film distributor through the water pump, the film distributor uniformly distributes the cooling liquid to the outer surface of the corrugated heat exchange tube bundle to form a liquid film, and the cooling liquid in the liquid film flows to the outer surface of the corrugated condenser tube bundle which is downwards discharged under the action of gravity; meanwhile, secondary steam finally effective from an evaporator (not shown in the figure) enters the first steam guide seal head through a secondary steam inlet, the secondary steam rapidly enters the tube side of the corrugated heat exchange tube in the first steam guide seal head, and the secondary steam entering the tube side exchanges heat with cooling liquid forming a liquid film outside the tube; condensing the secondary steam into condensate after heat release, and discharging the condensate from a condensate outlet; the cooling liquid phase absorbs the latent heat of the secondary steam and then starts to evaporate, the vapor evaporated by the cooling liquid phase is discharged into the atmosphere under the action of an exhaust fan, and meanwhile, the liquid material of the evaporated cooling liquid phase enters a filling area, and the liquid material entering the filling area is further supercooled when flowing downwards in a film shape. Because the corrugated heat exchange tube is arranged in the condensation cooler, the corrugated heat exchange tube replaces the prior straight heat exchange tube, so that the heat exchange efficiency is greatly improved, the condensation cooler is not required to be provided with equipment such as a cooling tower, and the investment cost is reduced.
