Abstract
The utility model discloses a shell and tube heat exchanger which comprises a housing, a heat exchange tube bundle arranged in the housing, pipe plates arranged at the two ends of the heat exchange tube bundle, and end covers arranged at the two ends of the housing respectively, wherein the end covers are connected with the pipe plates, a deflection baffle plate is arranged at the tube side part of the heat exchange tube bundle, the end covers at the two ends of the housing are provided with a medium I inlet and a medium I outlet respectively, a medium II inlet and a medium II outlet are formed at the upper and the lower parts of the housing respectively, the heat exchange tube bundle is formed by large-diameter heat exchange tubes and small-diameter heat exchange tubes which are made of polytetrafluoroethylene or polyperfluoro ethylene-propylene, and the large-diameter heat exchange tubes and the small-diameter heat exchange tubes are staggered in the housing. With the structure, the shell and tube heat exchanger can work in a corrosive working medium environment, ensures that the working medium in the pipe is full when the flow of the working medium is small, and improves the heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, specifically relates to a kind of tubular heat exchanger.
Background technology
Tubular heat exchanger is a kind of general heat transmission equipment; It has advantages such as simple in structure, sturdy and durable, cheap, of many uses, convenience for washing, adaptability be strong; Be a kind of chemical industry commonly used or heating plant equipment, be used to the heat exchange of chemical process or urban heating.The structure of existing tubular heat exchanger mainly comprises housing, is provided with heat-exchanging tube bundle in this housing, and tube sheet is equipped with at the two ends of heat-exchanging tube bundle; The two ends of said housing are respectively equipped with end socket, and end socket links to each other with tube sheet, and the tube side of said heat-exchanging tube bundle partly is provided with baffle plate; The end socket at said housing two ends is respectively equipped with medium I import and medium I outlet; The upper and lower of housing is respectively equipped with medium II import and medium II outlet, and heat-exchanging tube bundle generally adopts the heat exchanger tube that waits bore, and the heat exchanger tube material adopts the carbon steel material making more; The problem that this tubular heat exchanger exists is: when 1, the working media flow is little; Heat exchanger tube can not be full of working media fully, has so just wasted the heat exchange area of heat exchanger tube, and heat exchange efficiency is low; 2, when working media has corrosivity, the heat exchanger tube of carbon steel material can't adapt to the working environment needs.
The utility model content
The technical problem that the utility model will solve provides the tubular heat exchanger that a kind of heat exchange efficiency is high and can in having corrosivity working media environment, work.
For solving the problems of the technologies described above, a kind of tubular heat exchanger of the utility model comprises housing; Be provided with heat-exchanging tube bundle in this housing, tube sheet is equipped with at the two ends of heat-exchanging tube bundle, and the two ends of said housing are respectively equipped with end socket; End socket links to each other with tube sheet; The tube side of said heat-exchanging tube bundle partly is provided with baffle plate, and the end socket at said housing two ends is respectively equipped with medium I import and medium I outlet, and the upper and lower of housing is respectively equipped with medium II import and medium II outlet; Big footpath heat exchanger tube and path heat exchanger tube that said heat-exchanging tube bundle is processed by polytetrafluoroethylene (PTFE) or perfluoroethylene-propylene are formed, and big footpath heat exchanger tube and path heat exchanger tube are crisscross arranged in said housing.
Adopt the tubular heat exchanger of said structure; Because big footpath heat exchanger tube and path heat exchanger tube that said heat-exchanging tube bundle is processed by polytetrafluoroethylene (PTFE) or perfluoroethylene-propylene are formed; Big footpath heat exchanger tube is crisscross arranged in said housing with the path heat exchanger tube, so heat exchanger tube can work in having corrosivity working media environment, has the less path heat exchanger tube of caliber owing in the heat exchanger tube; Therefore working media full state in the working media flow hour also can guarantee to manage, heat exchange efficiency is high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done to specify further.
Fig. 1 is that sketch map cuts open in the master office of looking of a kind of tubular heat exchanger of the utility model.
Fig. 2 is the side-looking structural representation of tubular heat exchanger shown in Figure 1.
The specific embodiment
Referring to Fig. 1, Fig. 2, a kind of tubular heat exchanger of a kind of tubular heat exchanger of the utility model comprises housing 1; Be provided with heat-exchanging tube bundle 2 in this housing 1; Tube sheet 3 is equipped with at the two ends of heat-exchanging tube bundle 2, and the two ends of said housing 1 are respectively equipped with end socket 4, and end socket 4 links to each other with tube sheet 3; The tube side of said heat-exchanging tube bundle 2 partly is provided with baffle plate 5; The end socket 4 at said housing 1 two ends is respectively equipped with medium I import 6 and medium I outlet 7, and the upper and lower of housing 1 is respectively equipped with medium II import 8 and medium II outlet 9, and the big footpath heat exchanger tube 10 that said heat-exchanging tube bundle 2 is processed by polytetrafluoroethylene (PTFE) or perfluoroethylene-propylene is formed with path heat exchanger tube 11; Big footpath heat exchanger tube 10 is crisscross arranged in said housing 1 with path heat exchanger tube 11, and the caliber of said big footpath heat exchanger tube 10 is greater than the caliber of path heat exchanger tube 11.
