Description

[0001] The present invention relates to a rotary valve of a regenerative thermal oxidizer,

The present invention relates to a rotary valve of a regenerative type combustion apparatus for oxidizing a volatile organic compound, and more particularly, to a rotary valve of a regenerative type combustion apparatus which is provided with a seal portion at the outer periphery of a gas inlet hole of a hollow shaft, And the gas shield plate is fixedly coupled as the coupling bolt so that the VOC gas that is harmful to the human body flowing through the gas inflow hole can be completely shielded from the outside through the shield plate, The rotor and the hollow shaft communicating therewith can be easily adjusted so that the rotor can be always fixed at a predetermined position and the base portion supporting the rotor and the hollow shaft can be moved forward and backward And a support member vertically installed on left and right sides, It is an object of the present invention to prevent the occurrence of a load due to a load of an assembling part of the same heat accumulating combustor and to prevent a gap between a hollow shaft and an inlet and an outlet duct which are connected to the rotor, Torque sensors are connected to the drive motor for rotational drive to constantly adjust the rotational angle of the rotor and the hollow shaft and the like so that the simple structure of the regenerative combustion device facilitates manufacture and installation To a rotary valve of a regenerative combustion device.

Generally known volatile organic compounds (VOCs) are highly flammable and cause safety accidents due to fire explosion. In addition, as a main cause of air pollution, such VOCs are typically represented by alkane gas such as methane Alcohols such as methanol, low molecular hydrocarbons such as benzene and toluene, halogen aromatic compounds such as chlorobenzene, and halogen solvents such as trichloroethane and tricoloroethene.

VOC treatment apparatuses for removing VOCs which are not only attracted to the atmosphere and cause odor but also pollute the atmospheric environment have been developed. Such VOC treatment apparatuses include a combustion oxidation apparatus, a biological In the regenerative type combustion apparatus, a regenerative type combustion apparatus is installed in a combustor to heat the incoming VOC, and the oxidized VOC is discharged to the outlet When discharged, it absorbs the heat and heats the incoming VOC again.

As shown in FIG. 1, the VOC combustion oxidation apparatus includes a chamber 5 provided therein and an inlet (not shown) to the one side of the regenerative combustion unit 1 provided with a combustion chamber 6 above the VOC combustion oxidation apparatus. A wind direction switching rotary part (6) having a duct (7) formed therein, a discharge duct (8) formed on one side thereof, a gas discharge hole (9) 3 and a hollow shaft 12 in which an inlet hole 11 is formed is connected to the lower side of the hollow shaft 12. A belt or a chain 14 is connected to the hollow shaft 12 via a drive motor 15 and a pulley 13 The partition plate 16 is provided in the chamber 5 and the partition plate 17 and the catalyst plate 18 and the heat storage plate 16 are provided on the upper portion of the partition plate 16, And a burner 20 is installed on one side of the combustion chamber 6 installed on the upper part of the chamber 5 so that the 12- The VOC gas introduced into the chamber 5 flows into the combustion chamber 6 through the catalyst plate 18 and the heat storage plate 19 so that the gas of the harmful component is burned and oxidized by the burner 20, 8).

In the case of the above VOC combustion oxidation apparatus, the driving unit 4 simply drives the driving motor 15 to rotate the pulley 13 installed integrally with the hollow shaft 12 through the belt or chain 14 So that the hollow shaft 12 of the wind direction switching rotary part 3 is continuously rotated at a constant speed and the VOC which is a noxious gas is discharged to the atmosphere through the discharge duct 8 in an incompletely burnt state, It is not only deteriorating the efficiency but also destroying the environment caused by air pollution.

Recently, the hollow shaft and the rotor are rotated at a predetermined angle by the action of the push rod interposed between the air cylinder and the air cylinder, so that the air in the state where the noxious gas is supplied and the combustion air is changed to clean air is discharged to the atmosphere, A rotary valve assembly for a regenerative thermal oxidation system is known from Korean Utility Model Registration No. 20-0339936.

2, a combustion chamber 6 is provided in an upper part of the inside of the regenerative type combustion part 1, and an inlet duct 7 is provided at a lower side of the regenerative type combustion part 1 And a hollow shaft 12 is communicated to the lower side of the center of the rotor 3 in which the discharge duct 8 is formed on one side of the upper side facing the inflow duct 7, The push rod 22 is communicated with the air cylinder 24 while the air cylinder 24 is rotationally driven via the drive motor 20 And is disposed to one side of the rotary wheel (23).

The air cylinder 24 and the push rod 22 provided at one side of the rotary wheel 23 are rotated by the rotation of the rotary wheel 23 by the drive of the drive motor 20, (Not shown), which is rotated in one direction by the operation of the air cylinder 24 while being moved forward and backward in a reciprocating motion, The hollow shaft 12 is rotated so that the rotor 3 communicated with the hollow shaft 12 is rotated at a predetermined angle to supply the noxious gas and to discharge the air into the air atmosphere which is changed into the combustion and clean air.

However, in the rotary valve for a regenerative thermal oxidation system as described above, the push rod 22 interposed with the air cylinder 24 changes the rotational motion of the rotary wheel 23 into a linear reciprocating motion, After the VOC gas is introduced into the combustion chamber 6, the rotor 3 is stopped for a predetermined time, and after the combustion exhaust process, the VOC gas is again flowed again by a predetermined angle so that the exhaust process is repeated The rotor 3 is rotated at a predetermined angle and stopped for a predetermined period of time. However, rotation of the rotor 3 due to thermal expansion of the air cylinder is difficult to rotate and stop at an accurate position, There is a disadvantage that the VOC gas is discharged to the atmosphere through the discharge duct 8.

The rotor is supported on the air cushion A in such a manner that the rotor is always fixed at a fixed position while supporting loads such as the rotor 3 and the driving motor 20 on the lower side of the guide fixing shaft 21, The upper and lower positions of the rotor fluctuate due to the thermal expansion of the air cushion A due to the high temperature of the rotor 3 and the driving motor 20. As a result, There is a problem that a clearance is generated in a coupling portion between the hollow shaft and the inflow and outflow duct which are connected to the rotor.
