Description

Tube type heat exchanger
Technical Field
The utility model belongs to the heat exchanger field, concretely relates to shell and tube heat exchanger.
Background
In the face of the increasingly serious energy crisis, how to efficiently utilize the existing energy is the focus of increasing attention of people in all countries in the world. The heat exchanger is an energy-saving device for realizing heat transfer between materials between two or more fluids with different temperatures, is used for transferring heat from a higher fluid to a lower-temperature fluid, and is one of main devices for improving the energy utilization rate. The shell and tube heat exchanger is widely applied due to the reasons of simple structure, low cost, convenient maintenance and the like, and is very common industrial production equipment in various industries for exchanging heat of two fluids, such as chemical industry, metallurgy, medicine, electric power, heat energy and the like. However, the technical problem to be solved by those skilled in the art is how to improve the heat exchange efficiency of the tube type heat exchanger because the heat exchange efficiency of the tube type heat exchanger is low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple structure, use convenient, shell and tube heat exchanger that heat exchange efficiency is high, but make full use of medium heat improves heat utilization rate.
The purpose of the utility model is realized with the following mode:
a shell and tube heat exchanger comprising: barrel, first head, second head, first tube sheet, second tube sheet, heat exchange tube, baffle, material import, hot medium import, material export, hot medium export, first head and second head are connected with the barrel through the flange respectively, first tube sheet and second tube sheet fixed mounting are respectively in the left and right sides of barrel, material import and material export set up respectively at the middle part of first head and second seal coat head, and hot medium import and hot medium export set up respectively at the upper right side and the left downside of barrel.
Further, a heat insulation layer is arranged on the outer side of the cylinder body.
Further, a plurality of bulges are arranged on the outer side of the heat exchange tube.
Furthermore, the baffle is formed by connecting a plurality of groups of baffles in a staggered manner side by side.
Further, a buffer plate is arranged right below the heat medium inlet.
Further, the lower part of the second sealing head is provided with a discharge opening.
The utility model has the advantages that the heat preservation layer is arranged on the outer side of the cylinder body, which can reduce the loss of heat energy; the outer side of the heat exchange tube is provided with the bulges, so that the surface of the heat exchange tube is provided with the intervals, the contact area between a heat medium and a material is increased, and the heat exchange efficiency is improved; the buffer plate is arranged under the heat medium inlet, so that the impact of the heat medium on the outer wall of the heat transfer pipe can be relieved, and the service life of the heat exchange pipe is prolonged; the multiple groups of baffles are connected in a staggered manner side by side, so that the heat medium is in more comprehensive contact with the materials, and the accumulation of the heat medium is avoided; the lower part of the second seal head is provided with a discharge opening, so that materials can be discharged and treated in a concentrated manner at regular intervals.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The device comprises a barrel, a first end socket, a second end socket, a heat insulation layer, a first tube plate, a second tube plate, a heat exchange tube, a baffle, a protrusion, a material inlet, a heat medium inlet, a buffer plate, a material outlet, a discharge port and a heat medium outlet, wherein the barrel is 1-the barrel, the first end socket is 2-the first end socket, the second end socket is 3-the heat insulation layer, the first tube plate is 5-the second tube plate, the heat exchange tube is 7-the baffle, the protrusion is 9-the.
Detailed Description
As shown in fig. 1, a shell and tube heat exchanger includes: barrel (1), first head (2), second head (3), first tube sheet (5), second tube sheet (6), heat exchange tube (7), baffle (8), material import (10), heat medium import (11), material export (13), heat medium export (15), first head (2) and second head (3) are connected with barrel (1) through the flange respectively, first tube sheet (5) and second tube sheet (6) are fixed mounting respectively in the left and right sides of barrel (2), material import (10) and material export (13) set up respectively in the middle part of first head (2) and second head (3), and heat medium import (11) and heat medium export (15) set up respectively in the upper right side and the left downside of barrel (2).
Further, a heat insulation layer (10) is arranged on the outer side of the cylinder body (1).
Furthermore, a plurality of bulges (9) are arranged on the outer side of the heat exchange tube (7).
Furthermore, the baffle (8) is formed by connecting a plurality of groups of baffles in a staggered mode side by side.
Further, a buffer plate (4) is arranged right below the heat medium inlet (11).
Further, a discharge opening (14) is formed in the lower portion of the second sealing head (3).
The working principle is as follows: the material enters the heat exchange tube (7) from the material inlet (13) and flows out from the material outlet (13) after passing through the heat exchange tube (7); meanwhile, the heat medium enters from the heat medium inlet (15) and flows into the cylinder (2) under the action of the buffer plate (4), the flow direction of the heat medium is changed under the action of the baffle (8), heat transfer is realized on the materials in the heat exchange tube (7), and the heat medium flows out from the heat medium outlet (15). The buffer plate (4) can reduce the impact of the heat medium on the outer wall of the heat exchange tube (7).
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the general inventive concept, and it is intended to cover all such changes and modifications as fall within the true spirit and scope of the invention.
