Abstract
The utility model relates to a plate-fin spraying and falling film type heat exchanger used for refrigerating, air conditioning and chemical industry; the utility model is characterized in that a shell is included, and a steaming tube and a discharging tube are respectively provided above the shell and below the shell; the lower part of shell is provided a plate-fin heat exchanger which is composed of a plurality of plate-in heat exchanging components, and the upper part of the plate-fin heat exchanger is provided with a plurality of spraying pipes which are provided with a plurality small holes; the liquid is absorbed and sprayed on the plate-fin heat exchanger below to form falling film through the spraying pipe. The advantages of the utility model are that the structure is compact, the effect of heat transfer and mass transfer is fine, the cost is low and the utility model can be widely used in refrigerating, air conditioning and chemical industry.
Description
The plate-fin spray film-lowering type heat and mass exchanger of industry such as the utility model relates to and a kind ofly is used for freezing, air-conditioning, chemical industry.
At present, employed film-lowering type heat and mass exchanger sprays the falling liquid film form based on shell-and-tube in the industries such as refrigeration, air-conditioning and chemical industry.According to different mass transfer purposes, shell-and-tube spray film-lowering type heat and mass exchanger can be divided into shell-and-tube spray film-lowering type absorber and shell-and-tube spray film-lowering type generator.In shell-and-tube spray film-lowering type absorber, as shown in Figure 1, absorb liquid and spray in the following front row tube bank 2, and drip on the following comb bundle 3 by the front row tube bank according to this by nozzle 1 part, it is dirty that liquid is liquid film along the tube wall outside.All the other liquid then are sprayed onto in the space between the shell.Being absorbed medium is gas 4, is full of between the shell, and a part is absorbed into film when contacting with liquid liquid film on the tube wall, and all the other directly contact and be absorbed with the drop 5 that is sprayed between the shell.Owing to generally will discharge when absorbing and absorb heat, the rising of liquid film temperature, absorbability are weakened, thereby be connected with cooling medium 6 in the pipe, be used to cool off liquid film, strengthen its absorbability.Shell-and-tube spray film-lowering type generator schematic structure is also as above schemed, in shell-and-tube spray falling liquid film gas generator, liquid takes place to spray in the following front row tube bank 2 by nozzle 1 part, and dripped on the following comb bundle 3 by the front row tube bank according to this, it is dirty that liquid is liquid film along the tube wall outside.Different is logically in the pipe has plenty of heat medium 6 with aforementioned tube shell-type spray film-lowering type absorber, is used to heat liquid film 7, and gas component is come out.Because this shell-and-tube spray falling liquid film equipment heat transfer coefficient is not high, make heat transfer area bigger, structure is not compact, and volume is big, investment is higher.In recent years, though plate-fin heat exchanger by the industrial quarters extensive use, yet do not used in the heat and mass as yet.
Therefore, the purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of effective plate-fin spray film-lowering type heat and mass exchanger of compact conformation, heat and mass that still adopts the spray film-lowering type with the plate-fin heat exchange element to be provided.
The technical solution of the utility model is achieved like this, it includes a housing, be equipped with steam pipe and discharging tube respectively at the housing upper and lower, the bottom is equipped with the plate-fin heat exchanger of being made up of a plurality of plate fin heat-exchanging elements, be equipped with the many showers that have a plurality of apertures on the top of plate-fin heat exchanger, absorption liquid is sprayed onto on the following plate-fin heat exchanger by shower and forms falling liquid film.
Because the utility model adopts plate-fin heat exchanger, compact conformation, heat and mass is effective, and cost is low, can be applicable in industry such as refrigeration, air-conditioning, chemical industry.
The utility model embodiment does an into explanation in conjunction with the accompanying drawings.
Fig. 1 is shell-and-tube spray film-lowering type heat and mass exchanger principle schematic;
Fig. 2 is the utility model structural front view;
Fig. 3 is the utility model structure side view;
Fig. 4 is a plate fin heat-exchanging component structure schematic diagram.
The utility model embodiment is used in the refrigeration system with lithium bromide absorption, shown in Fig. 2,3, it includes a housing 8, above the housing 8 with below be equipped with steam pipe 10 and discharging tube 13 respectively, housing 8 bottoms are equipped with the plate-fin heat exchanger of being made up of a plurality of plate fin heat-exchanging elements 9, be equipped with the many showers 11 that have a plurality of apertures on the top of plate-fin heat exchanger, absorption liquid is sprayed onto on the following plate-fin heat exchanger by shower and forms falling liquid film, by the plate-fin heat exchanger heat exchange.Each plate-fin heat exchanger is made up of with a plurality of plate fin heat-exchanging elements 9 tube connector 12 of two logical cold and hot media, by shown in Figure 4, each plate fin heat-exchanging element 9 is formed by two thin plates 14 and fin 15 encapsulation, can be little concaveconvex shape or be equipped with wing on the face of thin plate 14 formation falling liquid films, leave the gap between a plurality of plate fin heat-exchanging elements.The number of plies of plate fin heat-exchanging element, row's number can be set according to designing requirement, during fabrication, the withstand voltage properties test of 0.3Mpa need be carried out in plate fin heat-exchanging element inboard, and the assurance housing is not ganged up leakage with the external world and plate fin heat-exchanging element inboard under negative pressure, and indeformable.
