The anti-explosion device comprises a clamp spring which is provided with an upper opening and a lower opening and is arranged in the heating furnace waste gas emission pipe, a floating check valve located in the inner cavity of the clamp spring, a fire ring arranged at a waste gas emission opening of the heating furnace waste gas emission pipe and a liquefied gas supplying pipeline which is arranged on the outer part of the heating furnace waste gas emission pipe, is close to the ignition device of the fire ring and is connected with the ignition device, wherein a gas inlet is formed between the clamp spring and the waste gas emission opening; and the gas inlet is connected with a nitrogen inlet pipe which is arranged on the outer part of the heating furnace waste gas emission pipe. According to the anti-explosion device, through the nitrogen inlet pipe which is additionally arranged on the heating furnace waste gas emission pipe, when the ignition device cannot ignite, nitrogen is introduced in through the nitrogen inlet pipe, so that air in a space between the floating check valve and the waste gas emission opening is emitted completely, and the space is filled with nitrogen; and thus detonation is prevented when ignition of the ignition device is restored.
Description
Technical field
The present invention relates to waste gas treatment equipment and manufacture field, be specifically related to a kind of furnace exhaust delivery pipe explosion-proof
Device.
Background technology
The waste gas that FBQ series heating furnace produces is mainly composed of carbon monoxide and hydrogen, due to carbon monoxide and hydrogen
The concentration of gas can be exploded after reaching a certain amount, it is therefore necessary to takes necessity on furnace exhaust delivery pipe
Explosion precaution.
Refer to Fig. 1, it illustrates the structure of a kind of furnace exhaust delivery pipe explosion-protection equipment of the prior art
Schematic diagram, it includes the jump ring 3 with upper and lower opening being arranged in furnace exhaust delivery pipe 1 and is positioned at
Floating check valve 2 in jump ring 3 inner chamber, is arranged on the fire at the Waste gas outlet of furnace exhaust delivery pipe 1
Circle 4, is arranged on the igniter 5 on pyrosphere 4 side, and igniter 5 passes through liquefied gas steam line 6 with outer
The liquefied gas supply equipment in portion connects.Igniter 5 lights pyrosphere 4, and pyrosphere 4 makes the oxidation in waste gas
Carbon and combustion of hydrogen, prevent fuel gas accumulation from causing security incident.When liquefied gas steam line 6 or igniting
Device 5 self breaks down when cannot light pyrosphere 4, and the imflammable gas in waste gas can not burn, in order to
Prevent waste gas and air from being entered the furnace chamber of heating furnace by suck-back, make to float unidirectional by reducing the air pressure in furnace chamber
Valve 2 moves downward and blocks the opening of jump ring 3 lower end and is isolated from the outside with the furnace chamber realizing heating furnace.
Though furnace exhaust delivery pipe explosion-protection equipment of the prior art has following defects that floating check valve 2
The opening that so can block jump ring 3 lower end in time is isolated from the outside with the furnace chamber realizing heating furnace, but it is single to float
Air is had to enter in the pipeline between valve 2 and Waste gas outlet, after igniter 5 recovers igniting, floating
Dynamic check valve 2 departs from the moment of jump ring 3 lower ending opening, and the fuel gas in stove mixes with air and acutely fires
Burn, easily produce detonation.

The standby nitrogen feedway in portion connects.
It has the technical effect that, when total nitrogen air feed system breaks down, standby nitrogen feedway can
Nitrogen supply is provided in good time.
In a preferred embodiment, described second road nitrogen connecting tube is provided with the second ball valve.
It has the technical effect that the break-make controlling the second road nitrogen connecting tube, when total nitrogen air feed system is normal
During the supply of nitrogen, the second ball valve is off.
Accompanying drawing explanation
Fig. 1 is the structural representation of furnace exhaust delivery pipe explosion-protection equipment in prior art；
Fig. 2 is the structural representation of the furnace exhaust delivery pipe explosion-protection equipment in the present invention.
Detailed description of the invention
As in figure 2 it is shown, in a specific embodiment, the explosion-proof dress of furnace exhaust delivery pipe in the present invention
Put the jump ring 23 with upper and lower opening including being arranged in described furnace exhaust delivery pipe 21 and be positioned at institute
State the floating check valve 22 in jump ring 23 inner chamber, be arranged on the waste gas row of described furnace exhaust delivery pipe 21
Put the pyrosphere 24 at mouth, be arranged on the outside of described furnace exhaust delivery pipe 21 and near described pyrosphere 24
Igniter 25 and the liquefied gas steam line 26 that is connected with described igniter 25.
When heating furnace runs well, the air pressure that the furnace chamber of heating furnace produces makes floating check valve 22 be lifted off card
The lower ending opening of spring 23, the upper and lower opening of jump ring 23 is the most unlimited, and the waste gas that heating furnace is discharged passes through heating furnace
The Waste gas outlet of exhaust pipe 21 is discharged smoothly.Igniter 25 is lighted pyrosphere 24 and is made in waste gas
Fuel gas (hydrogen and carbon monoxide) burns.
Being equipped with air inlet (not shown) on described furnace exhaust delivery pipe 21, described air inlet is positioned at institute
State between jump ring 23 and described Waste gas outlet, described air inlet be arranged on described furnace exhaust delivery pipe
Nitrogen inlet duct 27 outside 21 connects, and described nitrogen inlet duct 27 is provided with the first ball valve 27a and decompression
Valve 27b.The lower end of described nitrogen inlet duct 27 connects two-way nitrogen connecting tube, respectively first via nitrogen
Connecting tube 28 and the second road nitrogen connecting tube 29.Wherein, first via nitrogen connecting tube 28 and outside equipment
Total nitrogen air feed system connects, and the second road nitrogen connecting tube 29 is connected with outside standby nitrogen feedway.
Described second road nitrogen connecting tube 29 is provided with the second ball valve 29a.
When liquefied gas steam line 26 or igniter 25 self break down and cannot light pyrosphere 24, logical
Crossing the air pressure reduced in furnace chamber makes floating check valve 22 move downward and cover the opening of jump ring 23 lower end,
The furnace chamber realizing heating furnace is completely isolated with the external world, prevents waste gas and air suck-back from entering the furnace chamber of heating furnace.
Opening the first ball valve 27a on nitrogen inlet duct 27, and regulate air relief valve 27b, outside equipment is total
Nitrogen in nitrogen feedway enters nitrogen inlet duct 27 by first via nitrogen connecting tube 28, and finally leads to
Crossing the air inlet worn on furnace exhaust delivery pipe 21 to enter in exhaust pipe 21, will float check valve
Air between 22 and Waste gas outlet is all discharged, now between floating check valve 22 and Waste gas outlet
Nitrogen it is full of in pipeline.When igniter recovers igniting, and floating check valve 22 departs from the lower ending opening of jump ring
Moment, the fuel gas discharged in furnace chamber only contacts with nitrogen, thus is effectively prevented Vigorous gas burning,
Produce detonation.
When total nitrogen air feed system breaks down and causes being unable to supply nitrogen, open the second road nitrogen connecting tube
The second ball valve 29a on 29, the nitrogen in standby nitrogen feedway (not shown) passes through the second road nitrogen
Connecting tube 29 enters nitrogen inlet duct 27, the most at last air between floating check valve 22 and Waste gas outlet
All discharge.The standby nitrogen feedway used can be nitrogen cylinder or nitrogen pot.
Above the present invention has been carried out the most detailed description with certain particularity.General in art
Logical it is to be understood by the skilled artisans that what description in embodiment was merely exemplary, true without departing from the present invention
Make being changed on the premise of real spirit and scope and all should belong to protection scope of the present invention.Institute of the present invention
Claimed scope be defined by described claims rather than above-mentioned by embodiment
Description limits.
