A solid adsorption refrigeration adsorber for waste heat recovery of exhaust gas, belonging to the field of refrigeration technology, mainly composed of finned tubes with adsorbent inside, connecting tubes, connecting tubes and heat transfer gas channels, and the fins arranged in the channels The tube position is perpendicular or inclined to the direction of heat transfer gas movement. Compared with the existing adsorbers, it is easier to increase the heat transfer area of the heat transfer gas side by increasing the finning ratio of the finned tubes, and the convective heat transfer coefficient is high, which is conducive to the use of solid adsorption refrigeration for exhaust gas waste heat. recycling applications.
Description
The utility model is a kind of solid adsorption refrigeration to be used for the new adsorber structure that waste gas residual heat reclaims, and belongs to refrigeration technology field.
Solid adsorption refrigeration is an energy-conserving and environment-protective technology, and circulation drives available thermal source more than 70 ℃.Mainly comprise evaporimeter, condenser, choke valve and absorber etc. in its system, absorber also claims generator or adsorbent bed.Adsorbent in the absorber generally adopts molecular sieve, silica gel, active carbon, calcium chloride etc., and adsorbate generally adopts water, methyl alcohol, ammonia etc.
Absorber is the critical component in the solid adsorption refrigeration system, carries out heat exchange with adsorbent as the heat-transfer fluid of cold and heat source in absorber.The form of present absorber has and adopts shell-and-tube, board-like, plate-fin, spiral heat exchanger etc., wherein shell-and-tube heat exchanger adopts be heat-transfer fluid at tube side, adsorbent is at shell side.When heat-transfer fluid was liquid, these absorber patterns were proper, and when being used for heat-transfer fluid and being gas, the heat transfer resistance of this side is relatively just bigger, even very big temperature and pressure are arranged, heat-transfer area is still not enough.
The purpose of this utility model is to provide a kind of absorber of new structure, increases heat exchange area, makes it effectively to alleviate the relatively big contradiction of heat transfer resistance on heat transfer stream side, more helps the recovery of waste gas residual heat.
For realizing such goal of the invention, the adsorber structure of the utility model design comprises finned tube, connection pipe, tube connector and the heat-conducting gas passage of dress adsorbent in many groups, the position of its concrete member reaches each other, and annexation is: dress adsorbent in the finned tube, or the inclination vertical of its placement location with the heat-conducting gas direction of motion, shut for one, one is connected on the connection pipe, also can be connected on the connection pipe at two; Each is organized finned tube and is staggered on the direction of motion of heat-transfer fluid, also can arrange in proper order; Tube connector is connected on the connection pipe, and the wall that passes the heat-conducting gas passage is connected with the condenser of refrigeration system whole absorber with evaporimeter; Tube connector and connection Guan Jun are placed in the heat-conducting gas passage, also can be placed on outside the heat-conducting gas passage.
Tube connector can design one or more as the case may be, and the connection pipe can be designed to single hose, also can be whole header type, and the group number of finned tube and every group quantity are decided on the needs of heat-transfer surface.Pipe is outer can also to adopt suit, ratio-frequency welding, fin such as rolling to increase heat exchange area.In addition, because adsorbent is contained in the pipe, also can increase the heat transfer area of adsorbent by adjustment finned tube internal diameter.For whole header type, can be in the heat-conducting gas passage, also can be outside the heat-conducting gas passage or as the part of heat-conducting gas passage.
Below accompanying drawing by of the present utility model-individual embodiment describe in further detail.
Fig. 1 is a structural representation of the present utility model.
As seen, absorber is made up of finned tube 1, connection pipe 2, tube connector 3 and the heat-conducting gas passage 4 of interior dress adsorbent among the figure.Adsorbent is loaded in the finned tube 1,1 one of finned tubes are shut, one is connected on the connection pipe 2, arrow points is made as the heat-conducting gas direction of motion among the figure, the position of finned tube 1 is vertical with the heat-conducting gas direction of motion, and each is organized finned tube and is staggered, and tube connector 3 is welded on the connection pipe 2, finned tube 1 and connection pipe 2 all are placed in the heat-conducting gas passage 4, and the wall that tube connector 3 passes heat-conducting gas passage 4 is connected with the condenser of refrigeration system whole absorber with evaporimeter.
The utility model adopts packs adsorbent in the finned tube into, and every group of finned tube moves with heat-conducting gas Perpendicular direction or slant setting are organized finned tube more and are staggered in the direction of motion of heat-transfer fluid, establish Meter rationally can increase the coefficient of heat transfer effectively, reduces heat transfer resistance, can make the adsorbent of same quantity Obtain the refrigerating capacity bigger than other pattern absorber, with existing shell-and-tube, plate-fin, spiral Board-like absorber is compared, and can recently increase heat transfer gas by the wingization that improves finned tube with comparalive ease The heat exchange area on side, and heat-conducting gas cross-flow tube bank outside pipe are than vertical heat convection of plunderring tube bank The coefficient height is conducive to solid adsorption refrigeration is used for the application that waste gas residual heat reclaims, for example various in The UTILIZATION OF VESIDUAL HEAT IN of combustion machine emission or boiler flue vent gas.
