Abstract
The invention belongs to fire blast furnace gas boiler technical field, and in particular to a kind of equipment of reduction gas piping and valve erosion.The equipment of the reduction gas piping and valve erosion, including closed heating compartment, hot blast header, gas riser, boiler hot air recirculating system and branch gas tube, closed heating compartment splices fastening by adpting flange by the first heating compartment shell and the second heating compartment shell and formed, the hot blast header is connected by hot wind inlet pipe with closed heating compartment, and the closed heating compartment bottom is connected by hot-blast outlet pipe with boiler hot air recirculating system.Its advantage is：It is easy to inspect periodically the corrosion condition inside heating compartment, the moisture content in branch gas tube can be made non-condensing or evaporated again, the acidic materials reduced entrained by blast furnace gas of high degree are blocked to the burn into of the segment pipe and gas valve, can improve boiler energy utilization rate.
Description
Technical field
The invention belongs to fire blast furnace gas boiler technical field, and in particular to a kind of reduction gas piping and valve erosion
Equipment.
Background technology
In power plant for self-supply of steel plant frequently with combustion blast furnace gas boiler, combustion blast furnace gas boiler in, burner in corner,
Four layers of arrangement, typically install Hand-operated butterfly valve before burner, for controlling the heating furnace coal gas amount into burner.Boiler institute
With substantial amounts of acidic materials and saturated vapor is contained in blast furnace gas, these materials are affected by temperature, easily before burner
Hand-operated butterfly valve position forms acid solution, causes valve to damage.In existing process, integral replacing after the general coal gas using cut-out
The method of valve of being corroded is handled, and processing time is longer, and there is larger potential safety hazard, in addition, fails to see it
Its effective treating method.
The content of the invention
There is provided a kind of equipment for reducing gas piping and valve erosion for defect of the invention in order to make up prior art.
The present invention is achieved through the following technical solutions：
A kind of equipment for reducing gas piping and valve erosion, including closed heating compartment, hot blast header, gas riser, pot
Stove thermal wind sensor system and branch gas tube, closed heating compartment is by the first heating compartment shell and the second heating compartment shell
Splice fastening by adpting flange to form, the hot blast header is connected by hot wind inlet pipe with closed heating compartment, coal gas
Many branch gas tubes on standpipe pass through and are respectively equipped with gas butterfly valve, the closing on closed heating compartment, each branch gas tube
Formula heating compartment bottom is connected by hot-blast outlet pipe with boiler hot air recirculating system.
Further, the hot wind inlet pipe is connected with closed heating compartment upper end.
Further, the gas butterfly valve on the branch gas tube is located in closed heating compartment.
Further, the closed heating compartment is provided with inspection hand hole.
The beneficial effects of the invention are as follows：The equipment of a kind of reduction gas piping of the present invention and valve erosion is easy to inspect periodically
Corrosion condition inside heating compartment, can make the moisture content in branch gas tube non-condensing or be evaporated again, the reduction of high degree
Acidic materials entrained by blast furnace gas are blocked to the burn into of the segment pipe and gas valve, to ensure gas fired-boiler safety
Stable operation and operations staff's personal safety, and reduce maintenance cost；Meanwhile, the hot blast of heating tasks is completed through hot blast fairlead
Draw and enter thermal wind sensor system, boiler energy utilization rate can be improved.

A kind of equipment for reducing gas piping and valve erosion of the invention, boiler blast furnace gas is by gas riser when using
10 priorities pass through branch gas tube 9 and gas butterfly valve 11, and the first heating compartment shell 1 and the second heating compartment shell 2 pass through connection
The forming closed heating compartment of flange 3, the portions of branch gas tube 9 are wrapped up, to realize the heating to branch gas tube 9；
There is the hot blast of certain pressure（Heating source）The top of closed heating compartment is introduced by hot wind inlet pipe 4 by hot blast header 7,
Complete to draw the hot blast that temperature after the heating work of branch gas tube 9 is reduced by closed heating compartment bottom, through hot blast fairlead 5
Go to boiler hot air recirculating system 8.
The present invention is not limited to the above-described embodiments, anyone should learn the present invention enlightenment under make with the present invention
With same or like technical scheme, each fall within protection scope of the present invention.
The technology of the invention not being described in detail, shape, construction part are known technology.
