Abstract
The utility model relates to a connection structure between a gas-to-gas heat exchanger equipment body and an outside steel structure. The connection structure comprises an equipment support frame and a support steel structure, wherein the bottom of the equipment support frame is a plane, and the top of the support steel structure is a plane. A fluorine plastic plate material is pasted at the bottom of the equipment support frame, and a fluorine plastic plate material is pasted on the top of the support steel structure. And the fluorine plastic plate materials contact with each other. The connection structure can solve problems that when gas-to-gas heat exchanger equipment works, the equipment body is heated, and thereby stress is produced on a connection part, and a harmful effect is exerted on the equipment body and the support steel structure.
Description
Technical field
The utility model relates to a kind of syndeton of using in gas-gas heat exchanger, relate in particular to a kind of apparatus body of gas-gas heat exchanger and the syndeton between the outer steel structure.
Background technology
Utilize wet limestone-gypsum FGD to be widely used on the Chinese large-sized generating plant pulverized coal boiler.But, because the flue-gas temperature of processing through wet desulphurization is all lower, when the flue gas that temperature is excessively low is discharged from chimney, the buoyance lift height descends, the simultaneously also corresponding decline of the velocity of discharge of flue gas, be that chimney relative efficiency height reduces, cause to spread fully from the remaining harmful substance that chimney is discharged that ambient atmosphere is subject to severe contamination.Desulfurizer arranges heat exchanger and desulfuration absorbing tower can be exported the cigarette temperature and bring up to about 80 ℃, has both improved atmosphere hoist height, can reduce flue, chimney dewing corrosion behind the desulphurization plant simultaneously.
That generally use in the Desulfurization of Wet Limestone-gypsum engineering at present is swinging gas-gas heat exchanger GGH.But this class heat exchanger generally has and involves great expense, and energy consumption is large, particularly the higher shortcoming of air leak rate of air curtain.By contrast, tubular type gas-gas heat exchanger GGH have the heat transfer efficiency height, need not extra power, dead-tight characteristics, can overcome well the shortcoming of swinging GGH.
But no matter which kind of gas-gas heat exchanger all faces a common difficult problem, and that is exactly when gas-gas heat exchanger is worked, the apparatus body temperature raises, connecting portion in the heat exchanger especially adopts the position be fixedly connected with to produce stress, to producing harmful effect in service life of gas-gas heat exchanger.Connection between apparatus body and the outer steel structure uses bolt to fix substantially at present.Adopt this connected mode, when the apparatus body temperature raise, connecting portion produced stress, and equipment itself and supporting steel structure are produced harmful effect, thereby affected the service life of gas-gas heat exchanger.
The utility model content
The purpose of this utility model provides a kind of apparatus body of gas-gas heat exchanger and the syndeton between the outer steel structure, can solve when gas-gas heat exchanger equipment is worked, apparatus body is heated and makes connecting portion produce stress, thereby apparatus body and supporting steel structure are produced a dysgenic difficult problem.
Syndeton between the apparatus body of a kind of gas-gas heat exchanger of the present utility model and the outer steel structure comprises equipment supporter and supporting steel structure, wherein, the bottom of described equipment supporter is a plane, the top of described supporting steel structure is a plane, the bottom of described equipment supporter is pasted with fluoroplastics sheet material, the top of described supporting steel structure is pasted with fluoroplastics sheet material, contacts between the described fluoroplastics sheet material.Preferably, the size of the fluoroplastics sheet material of the top stickup of the size of the fluoroplastics sheet material of the bottom of described equipment supporter stickup and described supporting steel structure is complementary.
Adopt above-mentioned syndeton, when gas-gas heat exchanger is worked, the temperature of apparatus body raises, produce thermal expansion, two blocks of fluoroplastics sheet materials are because have good wearability and very low coefficient of friction, and do not have other members to be connected between two blocks of fluoroplastics sheet materials, so equipment and equipment supporter behind the expanded by heating are moved horizontally at the top of supporting steel structure, the effective compensation thermal expansion effects has reduced stress and has concentrated; Efficiently solve the technical barrier that the available technology adopting bolt is fixedly connected with equipment supporter and supporting steel structure generation stress rupture.

Description of reference numerals is as follows:
The specific embodiment
For making the auditor can further understand structure of the present utility model, feature and other purposes, now being accompanied by accompanying drawing in conjunction with appended preferred embodiment is described in detail as follows, use the illustrated embodiment of this accompanying drawing only to be used for the explanation the technical solution of the utility model, and non-limiting the utility model.
See also schematic diagram of the present utility model, Figure 1 shows that schematic diagram of the present utility model.The wherein apparatus body of gas-gas heat exchanger (GGH) and the syndeton between the outer steel structure, comprise equipment supporter 1 and supporting steel structure 4, wherein, the bottom 5 of described equipment supporter 1 is a plane, the top 6 of described supporting steel structure 4 is a plane, the bottom 5 of described equipment supporter 1 is pasted with fluoroplastics sheet material 2, and the top 6 of described supporting steel structure 4 is pasted with fluoroplastics sheet material 3, and described fluoroplastics sheet material 2 and described fluoroplastics sheet material 3 contact.The size of the size of described fluoroplastics sheet material 2 and described fluoroplastics sheet material 3 is complementary.
Adopt above-mentioned syndeton, when gas-gas heat exchanger is worked, the temperature of apparatus body raises, produce thermal expansion, be positioned at two blocks of fluoroplastics sheet materials of bottom 5 lower surfaces and top 6 upper surfaces, because have good wearability and very low coefficient of friction, and there are not other members to be connected between two blocks of fluoroplastics sheet materials, so equipment and equipment supporter 1 behind the expanded by heating are moved horizontally at the top 6 of supporting steel structure 4, the effective compensation thermal expansion effects, reduce stress and concentrated, thereby efficiently solved the technical barrier that the available technology adopting bolt is fixedly connected with equipment supporter 1 and supporting steel structure 4 generation stress ruptures.
What need statement is that above-mentioned utility model content and the specific embodiment are intended to prove the practical application of technical scheme that the utility model provides, and should not be construed as the restriction to the utility model protection domain.Those skilled in the art are in spirit of the present utility model and principle, when doing various modifications, being equal to and replacing or improve.Protection domain of the present utility model is as the criterion with appended claims.
