Technical field
The present invention relates to waste gas treatment equipment fields, more specifically, it relates to a kind of raising RTO furnace poppet sealing
The device of property.
Background technique
Heat accumulation type thermal incinerator (Regenerative Thermal Oxidizer abbreviation RTO) its principle is organic
Exhaust gas is heated to 800~850 DEG C, makes the VOCs oxygenolysis in exhaust gas at carbon dioxide and water.Aoxidize the high-temperature gas generated
Ceramic heat storage body is flowed through, ceramic heat storage body heating accumulation of heat is made, the regenerative chamber of heat storage state is used to preheat the organic waste of subsequent entrance
Gas.Regenerative chamber is divided into two Room or multicell, and each regenerative chamber successively undergoes the programs such as accumulation of heat-heat release-cleaning, in cycles, continuously
Work.
In waste gas treatment process system above-mentioned, to guarantee that each regenerative chamber smoothly switches, a kind of nonstandard valve is needed, it will
Valve is installed in pipeline, and valve plate is placed in regenerative chamber, under the impetus of cylinder, makes valve plate smooth opening or closing, complete
Normally switch at exhaust gas.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide a kind of sealings realized and promoted in valve shaft motion process, prevent
The only device of the raising RTO furnace poppet sealing of positive pressure exhaust gas leakage.
The device for improving the poppet sealing of RTO furnace is welded with stop sleeve, support sleeve by deep floor on flange
Cylinder upper end is welded with stop sleeve flange, and axle sleeve inner cylinder is welded on stop sleeve flange；Axle sleeve inner cylinder is nested with axle sleeve outer cylinder,
Axle sleeve outer cylinder is welded with axle sleeve drum flange, and axle sleeve drum flange is pressed abd fixed on stop sleeve method by fastening bolt and locking nut
Lan Shang；Axle sleeve inner cylinder is welded on flange, axle sleeve inner cylinder is nested with axle sleeve outer cylinder, and axle sleeve outer cylinder is welded with axle sleeve drum flange, axis
Sleeve flange is pressed abd fixed on flange by fastening bolt and locking nut；Promoted valve shaft by upper and lower two groups of axle sleeve outer cylinders with
Axle sleeve inner cylinder passes through stop sleeve；It is equipped with PTFE packing in the axial space that axle sleeve outer cylinder and axle sleeve inner cylinder surround and is wrapped in promotion
On valve shaft, and PTFE flange is equipped in axle sleeve outer cylinder side.
As preferred: the internal diameter of the PTFE flange is less than poppet shaft diameter, and PTFE flange outer diameter is less than axle sleeve inner cylinder
Internal diameter.
The beneficial effects of the present invention are:
1, structure is simple.Upper and lower two sets of flange shaft sleeve pressing devices are set, it is real while guaranteeing that axis does not shake vertically
Exhaust gas does not leak outside in existing pipeline；
2, long service life.Sealing is corrosion-resistant with PTFE packing, long service life；
3, practical.The up and down motion of promotion valve shaft is not influenced, the friction between axis and PTFE packing is reduced；
4, maintenance is convenient.In equipment downtime maintenance, it may be convenient to replace PTFE packing in sealing device.
Detailed description of the invention
Fig. 1 is closed state poppet valve arrangements schematic diagram；
Fig. 2 is poppet seal schematic device；
Description of symbols: valve shaft 1, axle sleeve drum flange 2, axle sleeve outer cylinder 3, PTFE flange 4, PTFE packing 5, axle sleeve are promoted
Inner cylinder 6, stop sleeve flange 7, stop sleeve 8, fastening bolt 9, locking nut 10, flange 11, deep floor 12, valve plate 13,
Cylinder 14, limit switch mounting box 15.
Specific embodiment
The present invention is described further below with reference to embodiment.The explanation of following embodiments is merely used to help understand this
Invention.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, also
Can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection scope of the claims in the present invention
It is interior.
Poppet is mainly by valve plate 13, cylinder 14, the equal main components composition of limit switch mounting box 15.Cylinder 14 is to be promoted
Valve provides power, pushes and promotes the up and down motion of valve shaft 1, is in valve plate 13 and turns on or off state；Limit switch mounting box
15 are primarily to facilitate limit switch installation, and poppet is detected in RTO exhaust treatment system PLC and is on or off state；Branch
Support set cylinder 8 promotes valve shaft for fixed, and takes sealing device, and exhaust gas in pipeline is made not leak outside.
The device of the raising RTO furnace poppet sealing of the present embodiment, is welded on flange 11 by deep floor 12
Stop sleeve 8,8 upper end of stop sleeve are welded with stop sleeve flange 7, axle sleeve inner cylinder 6 are welded on stop sleeve flange 7；Axis
Set inner cylinder 6 is nested with axle sleeve outer cylinder 3, and axle sleeve outer cylinder 3 is welded with axle sleeve drum flange 2, and axle sleeve drum flange 2 passes through 9 He of fastening bolt
Locking nut 10 is pressed abd fixed on stop sleeve flange 7；Axle sleeve inner cylinder 6 is welded on flange 11, axle sleeve inner cylinder 6 is nested with axis
Outer cylinder 3 is covered, axle sleeve outer cylinder 3 is welded with axle sleeve drum flange 2, and axle sleeve drum flange 2 compresses solid by fastening bolt 9 and locking nut 10
