Abstract
The utility model relates to a spirally-wound threaded tube bundle type tubular heat exchanger. The heat exchanger mainly comprises a casing (1), two thick tube plate (2) and a heat exchange tube bundle (4), wherein an upper sealing head (5) and a lower sealing head (6) are arranged at upper and lower ends of the casing (1) respectively, and baffle plates (7) are arranged in the casing (1). The heat exchanger is characterized in that small tube plates (3) with equal quantity are symmetrically arranged on the two thick tube plates (2), and the heat exchange tube bundle (4) is arranged between the two thick tube plates (2), and two ends are connected with the small tube plates (3). According to the heat exchanger, the heat exchange area of heat exchange tube nest per unit volume is increased, and the energy utilization rate is increased; heat exchange of the heat exchanger is uniform due to heat exchange tubes with equal lengths, and the heat exchange stability is improved; and the designed thick tube plates can be connected with the heat exchange tube nest in an expanded or welding manner, then the probability of leakage during a heat exchange process is low, deformation of the heat exchange tube nest is prevented, and the durability of a product is improved.
Description
Technical field
The utility model relates to a kind of thread helix and is wound around bundled tube tubular heat exchanger, is mainly used in chemical industry, food, and the heat exchanger of medical process, is applicable to the condensation of material.
Background technology
Mostly existing heat exchanger is shell-and-tube heat exchanger, traditional shell-and-tube heat exchanger generally adopts plain tube as heat transfer element, segmental baffle supports tube bank, deflection plate has again guide functions simultaneously, can improve the flow velocity of shell-side fluid, force fluid distance according to the rules repeatedly laterally by tube bank, the less turbulence of enhance fluid.When shell-side fluid flows, near break over region and import and export, the stagnant area of eddy current all can form mobile and heat transfer dead band, thereby has reduced heat transfer efficiency.Shell-side fluid transversal flow heat-exchanging tube bundle, causes larger flow resistance, and heat-exchanging tube bundle generation flow-induced vibration under large Reynolds number, and causes heat exchanger tube to be revealed and lost efficacy.Due to the temperature difference of outer fluid in pipe, thereby the housing of heat exchanger is also different with the temperature of tube bank, if two temperature difference differ greatly, in heat exchanger, by producing very large thermal stress, causes tube bending, fracture, or pulls from tube sheet.Therefore traditional shell-and-tube heat exchanger heat transfer area is little, heat exchanger effectiveness is low, and volume is large, and power consumption is larger, waste resource.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides the thread helix that a kind of heat exchange efficiency is high, energy consumption is little, fouling tendency is low, volume is little and easy to maintenance to be wound around bundled tube tubular heat exchanger.
The purpose of this utility model is achieved in that a kind of thread helix is wound around bundled tube tubular heat exchanger, described heat exchanger is mainly by housing, two thick tube sheets and heat-exchanging tube bundle composition, described two thick tube sheets are arranged at respectively the upper of enclosure interior, below, upper and lower two ends, outside at described housing are respectively arranged with upper cover and low head, on described upper cover and low head, be provided with import and export, in described housing, deflection plate is installed, on described two thick tube sheets, be symmetrically arranged with the little tube sheet that quantity equates, described heat-exchanging tube bundle is arranged between two thick tube sheets and two ends are connected with little tube sheet.
The mode that the two ends of described heat-exchanging tube bundle connect or weld by rising is connected with little tube sheet, and the mode that described little tube sheet connects or welds by rising is connected with thick tube sheet.
Described heat-exchanging tube bundle is formed by the mode of spiral winding by the above thread heat exchange pipes of three or three, and the cross section of heat exchanger tube after being wound around is equilateral triangle.
Described heat exchanger tube is thin-wall long and thin metal tube, and its metal tube outer wall has threaded line.
Compared with prior art, the utlity model has following beneficial effect:
1, the interior heat exchange area of unit volume of set of heat exchange tubes is strengthened, improved energy utilization rate.
2, it is even that isometric heat exchanger tube makes heat exchanger heat exchange, improved heat exchange, stability.
3, thick tube sheet design can adopt to rise and connect or welding manner, connects heat-exchanging tube bundle, makes in heat transfer process, to be difficult for leaking, and prevents set of heat exchange tubes distortion, the service life of having improved product.
4, heat transfer rate improves greatly.
5, easy to maintenance.
