Abstract
The utility model relates to a heat exchanger, which belongs to the technique field of heat exchange equipment. The utility model discloses a normal-temperature water purification rectangular tube shell heat exchanger, which comprises a housing, rectangular tube boxes, rectangular tube plates, a plurality of rectangular heat exchange tubes, a fluid inlet and a fluid outlet of the shell pass, a fluid inlet and a fluid outlet of the tube pass and a base. The heat exchanger is characterized in that the pair of rectangular tube boxes are connected with the cylindrical housing formed by rolling a thin plate into one piece. The pair of rectangular tube plates fixedly connected with the plurality of rectangular heat exchange tubes into one piece inside the housing are also fixedly connected with the housing. Tube groups are evenly arranged at intervals between the plurality of rectangular heat exchange tubes in a circumference with the housing axis as the center of the circumference. Cavities are formed between the rectangular tube boxes and the rectangular tube plates. The fluid inlet and the fluid outlet of the shell pass are connected with the housing via adapters so as to be welded on the housing. The fluid inlet and the fluid outlet of the tube pass are also connected with the housing via adapters so as to be welded on the housing. The heat exchanger of the utility model facilitates the heat exchange of water purification at a normal temperature, which also has the advantages of small occupation space, low manufacturing and installation cost and less investment.
Description
Technical field
The utility model relates to a kind of heat exchanger, belongs to the heat-exchange apparatus technical field.
Background technology
Existing shell-and-tube heat exchanger kind is more on the market, and majority is made up of bobbin carriage and housing two parts, imports and exports and uses flange to connect, and tube side fluid is entered by bobbin carriage, carries out heat exchange by restraining inside.Shell-side fluid is carried out heat exchange by restraining the outside.The employed material of bobbin carriage and housing mostly be carbon steel material, stainless steel material but heat exchanger tube then with copper pipe or carbon steel pipe, therefore, in use, just demonstrate following deficiency for the heat exchanger under the suitable normal temperature: 1, the employed material walls of bobbin carriage, heat exchanger tube and housing is thicker, cause consumptive material, cost big, be applicable to the heat exchange under the high-temperature high-pressure state; 2, heat exchanger tube mostly is cylindrical, and tube wall is thicker, and heat exchange area is little, and heat exchange efficiency is lower, makes troubles to the user.
Summary of the invention
The purpose of this utility model is, overcomes the above-mentioned defective of prior art, provides a kind of simple in structure, and cost is low, stable performance, heat conductive efficiency height, normal temperature water purification quarter bend shell heat exchanger easy to use.
Technical scheme
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind of normal temperature water purification quarter bend shell heat exchanger, comprise housing, quarter bend case, quarter bend plate, several rectangle heat exchanger tubes, shell-side fluid import, shell-side fluid outlet, tube side fluid import, tube side fluid outlet, base composition, it is characterized in that: the described cylindrical shell that is rolled by a pair of quarter bend case and thin plate connects as one, a pair of quarter bend plate and several rectangle heat exchanger tubes in the housing are fixed with one, and also are connected with housing; Described a kind of normal temperature water purification quarter bend shell heat exchanger, it is characterized in that: described several rectangle heat exchanger tubes are round dot with the housing axle center, the uniform nest of tubes that has gap arrangement in circumference, between quarter bend and the quarter bend; Described a kind of normal temperature water purification quarter bend shell heat exchanger is characterized in that: form cavity between described quarter bend case and the quarter bend plate; Described a kind of normal temperature water purification quarter bend shell heat exchanger is characterized in that: described shell-side fluid is imported and exported the connection of taking over and is welded on the housing, and tube side fluid is imported and exported the connection of taking over and is welded on the quarter bend case; Described a kind of normal temperature water purification quarter bend shell heat exchanger is characterized in that: described shell-side fluid is opposite with the tube side fluid hot and cold water flow direction, and cold water is low in and high out, and hot water is high in and low out.
Beneficial effect
Owing to adopted technical scheme described in the utility model, changed existing housing wall and the thicker situation of tube wall on the market, housing wall of making and rectangle heat exchange tube wall are compared thin, the heat exchange under the suitable normal temperature water purification, take up room little, the manufacturing cost mounting cost is low, has saved investment; Cavity between quarter bend case and the quarter bend plate, saved deflection plate, having solved incoagulable gas retains, avoided the slough, owing to adopt welding to be fixed as one between quarter bend case and the quarter bend plate, distance is constant between the pipe, has avoided collision, and several rectangle heat exchanger tubes are formed the heat exchange nest of tubes, circumference uniform distribution has clearance-type and arranges, this arrangement can make the heat transfer area of unit volume heat exchanger improve greatly, forms cavity between quarter bend case and the quarter bend plate, makes quarter bend plate surface area be effective heat exchange area, obviously improved stock utilization, simultaneously, the heat exchanger tube of heat exchanger is changed into the rectangle heat exchanger tube, material is a stainless steel, can further improve heat exchanger effectiveness of the present utility model, effectively increase the anti-ageing intensity of heat exchanger, further prevent the erosion of said solid impurity, improve heat exchanger effectiveness.
The utility model is described in further detail below in conjunction with accompanying drawing:
