Description
Technical field
The utility model relates to environmental protection and energy saving fields, and in particular to a kind of enamel pipe GGH.
Background technique
With the pay attention to day by day that Environmental is protected, the pollutant emission standard of waste incineration power generation project is substantially
It improves, for the discharge standard of harsh SOX, HCl and flue dust, major part project has been all made of wet process deacidifying process at present.By
It is about 60 ~ 80 DEG C in the neat stress temperature being discharged from wet process tower, will cause for wet saturation state if being directly discharged into chimney
Chimney is formed about water mist, that is, forms so-called " white cigarette ".Therefore, low-temperature flue gas heater is set usually after wet process depickling
GGH heats the neat stress after depickling using the former flue gas before wet process depickling, make flue-gas temperature by 60 ~ 80 DEG C promoted to
It 120 DEG C or so, so as to improve the rising height and diffusivity of neat stress, eliminates when neat stress is discharged from chimney and emits showing for white cigarette
As；Moreover, the alleviation of wet flue gas condensation also can reduce the corrosion to subsequent flue and chimney.For this low-temperature zone GGH(cigarette
Gas-flue gas heat-exchange unit) working environment, heat exchange material need to have stronger corrosion resistance, moreover, the flue gas of garbage power project
Middle HCL content is higher, and therefore, this low-temperature zone GGH need to have the stronger corrosion resistance for hydrochloric acid, common stainless steel and ND
Steel has been unable to satisfy requirement in this respect.Currently, what the GGH flue gas heat-exchange unit of low-temperature zone was all made of is expensive fluoroplastics
Heat exchange material, general data are difficult to bear.
Utility model content
To solve the above-mentioned problems in the prior art, it is de- that the utility model provides a kind of wet process that can preferably promote
Sour technique, and the enamel pipe GGH of the equipment cost of low-temperature zone GGH flue gas heat-exchange unit is effectively reduced.
The technical solution of the utility model is as follows: a kind of enamel pipe GGH, including bobbin carriage and connection flue, the bobbin carriage packet
Include heat exchanger tube, upper perforated plate and lower perforated plate, the heat exchanger tube is staggered in arrangement, the both ends of the heat exchanger tube be respectively welded at upper perforated plate with
On lower perforated plate, the upper plate pipe is equipped with former gas inlet, and the lower section of the lower plate pipe is equipped with support frame, the connection of support frame lower part
Former exhanst gas outlet, the bobbin carriage are externally provided with sealing frame, and the connection flue includes that neat stress import and neat stress export, described net
Gas inlet is located at the side of bobbin carriage, and the neat stress outlet is located at the other side of bobbin carriage.
Further, the surface of the neat stress import and neat stress outlet is welded with bitch and is covered with castable refractory.
Further, expansion joint is equipped at the former gas inlet.
The utility model improves the rising height and diffusivity of neat stress, eliminates when neat stress is discharged from chimney and emits
The phenomenon that white cigarette, and the corrosion to subsequent flue and chimney is alleviated, wet process deacidifying process can be preferably promoted, and be effectively reduced
The equipment cost of low-temperature zone GGH flue gas heat-exchange unit.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model；
In figure: 1- heat exchanger tube, 2- upper perforated plate, 3- lower perforated plate, 4- neat stress import, the outlet of 5- neat stress, 6- support frame, 7-
Expansion joint, 8- bitch, 9- castable refractory, 10- sealing frame, 11- original gas inlet, 12- original exhanst gas outlet.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail:
As shown in Figs. 1-2, a kind of enamel pipe GGH, including bobbin carriage and connection flue, the bobbin carriage includes heat exchanger tube 1, upper tube
Plate 2 and lower perforated plate 3, the heat exchanger tube 1 are staggered in arrangement, and the both ends of the heat exchanger tube 1 are respectively welded at upper perforated plate 2 and lower perforated plate 3
On, the upper plate pipe 2 is equipped with former gas inlet 11, it is equipped with expansion joint 7 at the original gas inlet 11, the lower plate pipe 3
Lower section is equipped with support frame 6, and 6 lower part of support frame connects former exhanst gas outlet 12, and the bobbin carriage is externally provided with sealing frame 10, the connection cigarette
Road includes neat stress import 4 and neat stress outlet 5, and the neat stress import 4 is located at the side of bobbin carriage, the neat stress outlet 5
It is located at the other side of bobbin carriage, the surface that the neat stress import 4 and neat stress export 5 is welded with bitch 8 and is covered with refractory casting
Material 9.
The original flue gas flows from top to bottom in heat exchanger tube 1, and neat stress makees lateral flow outside heat exchanger tube 1.
The heat exchanger tube 1 selects ordinary carbon steel material, and exchanges 1 inner and outer surfaces of heat pipe and protected using plating vitreous enamel is burnt；Institute
The surface for stating upper perforated plate 2, lower perforated plate 3, sealing frame 10 and expansion joint 7 is all made of the micro- melting welding protection processing of low temperature；The connection cigarette
The surface of road and smoke contacts is all made of welding bitch 8 and applies castable refractory 9 and protected.
The utility model improves the rising height and diffusivity of neat stress, eliminates when neat stress is discharged from chimney and emits
The phenomenon that white cigarette, and the corrosion to subsequent flue and chimney is alleviated, wet process deacidifying process can be preferably promoted, and be effectively reduced
The equipment cost of low-temperature zone GGH flue gas heat-exchange unit.
