Abstract
The utility model relates to a detachable all-welded plate-shell heat exchanger which comprises a shell. The detachable all-welded plate-shell heat exchanger further comprises a heating medium inlet and outlet pipe box, bolts, a refrigerant outlet pipe box, a plate bundle body, a heating medium retracing pipe box, a support base component, a refrigerant inlet pipe box and a thermal compensation device. The heating medium inlet and outlet pipe box, the shell, the refrigerant outlet pipe box, the plate bundle body, the heating medium retracing pipe box, the support base component and the refrigerant inlet pipe box form a whole body through the bolts. The thermal compensation device is composed of a fixed block, a connecting plate and a square expansion joint, and is welded to the shell through the plate bundle body. The heating medium retracing pipe box is mounted on the right side of the shell, and an exhaust interface and a blowdown interface are respectively arranged up and down on the heating medium retracing pipe box. The detachable all-welded plate-shell heat exchanger effectively solves the problems of heat exchanger thermal stress cracks, leakage and the like, prolongs the service life, and can be more widely applied to the fields of iron and steel, energy, petrochemical engineering, electric power, civil supply of heat and the like, and has the advantages of being efficient, easy to wash, energy-saving, reliable in operation and the like.
Description
Technical field
The utility model relates to a kind of heat exchanger, especially relates to a kind of removable full welded plate shell heat exchanger.
Background technology
Removable full welded plate shell heat exchanger is a kind of new type heat exchanger that development in recent years is got up, and it has coefficient of heat transfer height, volume compact, high temperature resistant (>=400 ℃), high pressure resistant (>=advantage such as 20MPa).This heat exchanger has been concentrated the advantage of spiral heat exchanger and removable plate type heat exchanger; It is low to have overcome the spiral heat exchanger coefficient of heat transfer simultaneously; Volume is big, is difficult for cleaning and removable plate type heat exchanger non-refractory, high pressure, the flimsy shortcoming of sealing gasket, has good development space.But this heat exchanger also has weak point, mainly is that structure is relatively complicated, and manufacturing process requirement is higher; Wherein thermal compensation device be provided with very crucially, handles badly in use will produce crack due to thermal stress, the general use is no more than 1 year and leakage will occur.Therefore be badly in need of that a kind of use is safer, the heat exchanger of longer service life.
The utility model content
For the weak point in addressing the above problem, the utility model provides a kind of removable full welded plate shell heat exchanger.
In order to solve above technical problem; The technical scheme that the utility model adopted is: a kind of removable full welded plate shell heat exchanger; Comprise shell, it comprises that also heating agent turnover bobbin carriage, bolt, refrigerant go out bobbin carriage, plate bundle body, heating agent turn back bobbin carriage, mounting assembly, refrigerant inlet pipe case and thermal compensation device; Heating agent turnover bobbin carriage, shell, refrigerant go out turn back bobbin carriage, mounting assembly and refrigerant inlet pipe case of bobbin carriage, plate bundle body, heating agent and connect into an integral body through bolt; Thermal compensation device is made up of fixed block, connecting plate and square expansion joint, and thermal compensation device is through the welding of plate Shu Tiyu shell.
The right-hand member of shell is provided with the heating agent bobbin carriage that turns back, and what said heating agent turned back bobbin carriage is respectively arranged with exhaust port and blowdown interface up and down.
The utility model efficiently solves the problem of exchanger heat stress cracking, leakage, and extend to 40 months the service life of the utility model, and crackle, leakage do not take place again in stable and reliable operation.Can be widely used in fields such as iron and steel, the energy, petrochemical industry, electric power, domestic heating more, have efficient, advantage such as be prone to clean, energy-conservation, reliable.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Fig. 3 is the thermal compensation device structure for amplifying sketch map of the utility model among Fig. 1.
The specific embodiment
Like Fig. 1-shown in Figure 3, the utility model comprises that heating agent turnover bobbin carriage 1, bolt 2, shell 3, refrigerant go out bobbin carriage 4, plate bundle body 5, heating agent turn back bobbin carriage 6, mounting assembly 7, refrigerant inlet pipe case 8 and thermal compensation device.The heating agent of the utility model turnover bobbin carriage 1, shell 3, refrigerant go out turn back bobbin carriage 6, mounting assembly 7 and refrigerant inlet pipe case 8 of bobbin carriage 4, plate bundle body 5, heating agent and connect into an integral body through bolt 2.
Thermal compensation device is made up of fixed block 9, connecting plate 10, square expansion joint 11, and through plate bundle body 5 and shell welding.
Thermal medium is turned back by the heating agent bobbin carriage 6 that turns back through plate bundle body 5 from the entering suitable for reading of heating agent turnover bobbin carriage 1, flows out through the end opening of heat medium produce hose case 1.The refrigerant medium goes out bobbin carriage suitable for reading outflow through plate bundle body by refrigerant from the end opening entering of refrigerant inlet pipe case 8.Thermal medium and refrigerant medium form the adverse current state in plate bundle body, under cold and hot medium turbulence state, carry out the dividing wall type exchange.
What the heating agent that is positioned at the shell right-hand member turned back bobbin carriage 6 is respectively arranged with exhaust port and blowdown interface up and down.Shell with adopt bolt to be connected with bobbin carriage.This heat exchanger after using one-period is pulled down left and right sides bobbin carriage, to this heat exchanger clean, scrubbing.
Thermal compensation device carries out playing in the cold and hot exchange process thermal compensation effect cold and hot matchmaker.When heat exchanger in the use can't be dismantled, also can lead to the online purging of steam, thermal compensation device has been alleviated the thermal deformation that is produced by steam during this period.Guaranteed the safe and reliable of this heat exchanger.
More than technical scheme that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper principle and the embodiment of the utility model embodiment are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the utility model embodiment; Simultaneously, for one of ordinary skill in the art, according to the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.All distortion that has the utility model to cause all belong to by the protection domain of utility model.
