Abstract
The utility model discloses a kind of wet desulphurization chimney heating systems, including gas furnace flue and wet desulphurization chimney, wet desulphurization chimney is connected to wet desulfurization flue gas delivery pipe, it further include air-introduced machine, it is connected to induced duct between gas furnace flue and wet desulphurization chimney, air-introduced machine, which is placed in induced duct, makes gas furnace flue gas enter in wet desulphurization chimney, and the junction of induced duct and wet desulphurization chimney is located near wet desulfurization flue gas delivery pipe and wet desulphurization chimney connectivity part.The wet desulphurization chimney heating system effectively eliminates wet desulphurization flue and emits white vapour, reduces condensate corrosion flue inner wall.
Description
Technical field：
The utility model is related to a kind of wet desulphurization chimney renovation techniques, are especially a kind of wet desulphurization chimney heating system
System.
Background technology：
Since wet desulfurization flue gas is about 50 degree of saturation vapour, as long as autumn and winter has temperature drop to be easy for condensate generation
Chimney will emit white vapour, especially temperature and be down to 15 degree or less to emit white vapour most apparent.In addition, according to national regulation principle, gas
Fuel positive pressure stove can not share a chimney, thus gas furnace flue gases duct and wet desulfurization flue gas with solid fuel negative pressure stove
Mutually independent two flue gases ducts when flue.After traditional wet desulfurization flue gas processing, flue-gas temperature≤50 DEG C, and be wet
Degree is in saturation state, when flue gas generates temperature drop in the transmission process of flue and chimney, just has a large amount of condensate and is precipitated, and
Contain a large amount of acidic materials in the condensate of precipitation, such as sulfuric acid, corrosivity is extremely strong in the case of 50 DEG C, many unit power plant because
For such corrosion, chimney is built again or corrosion prevention operation periodically is carried out to flue and chimney.
Utility model content：
It effectively eliminating wet desulphurization flue technical problem to be solved by the utility model is to provide one kind and emits white vapour, subtracts
The wet desulphurization chimney heating system of few condensate corrosion flue inner wall.
The technical solution of the utility model is to provide a kind of wet desulphurization chimney heating system, including gas furnace
Flue and wet desulphurization chimney, wet desulphurization chimney are connected to wet desulfurization flue gas delivery pipe, further include air-introduced machine, gas furnace
Induced duct is connected between flue and wet desulphurization chimney, air-introduced machine, which is placed in induced duct, makes gas furnace flue gas enter wet desulphurization
In chimney, the junction of induced duct and wet desulphurization chimney is located at wet desulfurization flue gas delivery pipe and wet desulphurization chimney connectivity part
Near.
After using the above structure compared with prior art, the utility model has the following advantages：Air-introduced machine is gas furnace
Flue gas is introduced into wet desulfurization flue gas flue to promote wet desulfurization flue gas temperature, efficiently solves autumn and winter because temperature declines
So that chimney emits the problem of white vapour, and the investment for trnasforming urban land cost is very light, energy-saving and environment-friendly, and solves the problems, such as well.
Preferably, further including pneumatic cut-off valve, pneumatic cut-off valve is arranged on induced duct, pneumatic cut-off valve and air-introduced machine
Interlocking is interactive.When air-introduced machine breaks down, operated pneumatic valve can be shut automatically, and two chimney channels of cut-out ensure to be independent of each other.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figure 1, a kind of wet desulphurization chimney heating system, including gas furnace flue 1 and wet desulphurization chimney 2,
Gas furnace flue 2 is connect with gas furnace, and wet desulphurization chimney 2 is connected to wet desulfurization flue gas delivery pipe 3, de- by wet method
Sulphur chimney discharges wet desulfurization flue gas, further includes the air-introduced machine 5 of a 15KW, gas furnace flue 1 and wet desulphurization chimney 2
Between be connected to induced duct 4, air-introduced machine 5, which is placed in induced duct 4, makes gas furnace flue gas enter in wet desulphurization chimney 2, induced duct 4
It is located near wet desulfurization flue gas delivery pipe 3 and 2 connectivity part of wet desulphurization chimney with the junction of wet desulphurization chimney 2.It is true
It ensures safety, further includes pneumatic cut-off valve 6, pneumatic cut-off valve 6 is arranged on induced duct 4, and pneumatic cut-off valve 6 is interlocked with air-introduced machine 5
It is interactive.When air-introduced machine breaks down, operated pneumatic valve can be shut automatically, and two chimney channels of cut-out ensure to be independent of each other.
Since wet desulfurization flue gas is about 50 DEG C of saturation vapour, as long as autumn and winter has temperature drop to be easy for condensate generation
Chimney will emit white vapour, especially temperature and be down to 15 degree or less to emit white vapour most apparent.With a 15KW air-introduced machine by gas furnace
(200 DEG C) of flue gas is sent into wet desulfurization flue gas flue, since the about 200 DEG C of dryings of gas furnace flue-gas temperature are free of steam by drawing
After wind turbine imports wet desulfurization flue gas flue, greatly improving the temperature of wet desulfurization flue gas makes its actual temperature all in saturated water
50 degree of stripping temperature or more, such condensate, which would not generate, to be efficiently solved chimney breast and emits white vapour phenomenon.The heating system solution
Certainly wet desulphurization chimney winter emits white vapour, and perishable inner wall, the required less expense of the material used is low and Maintenance and Repair are convenient.Through
Practice in a device uses, and effect is highly desirable.
Only the utility model preferred embodiment is described above, but is not to be construed as the limit to claim
System.Every equivalent structure or equivalent flow shift done using the utility model specification and accompanying drawing content is included in this
Within the scope of patent protection of utility model.
