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 rotor The gas shielding plate is fixedly coupled with the sealing bolt through the sealing portion so that the VOC gas that is harmful to the human body flowing through the gas inlet hole can be completely shielded from the leakage of the gas to the outside through the shield plate, And a hollow shaft connected to the rotor and the rotor through a screw shaft connected to the rotor and the hollow shaft so that the rotor can be always fixed at a fixed position, And the base portion is vertically arranged on the front, rear, left and right sides of the base portion And prevents the generation of a load due to the assembly load of the heat accumulating combustor such as the rotor and the hollow shaft and prevents the gap between the hollow shaft and the inlet and outlet ducts, Of course, a torque sensor is connected to the rotor and a drive motor for rotationally driving the hollow shaft to communicate with the rotor, so that the rotation angle of the rotor and the hollow shaft can be constantly adjusted, The present invention relates to a rotary valve of a regenerative combustion device, which can be easily manufactured and installed by a simple structure of a combustion device.

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

VOC treatment apparatuses for removing VOCs that are not only attracted to the atmosphere and cause odors but also are a pollution source of the atmospheric environment have been developed. The VOC treatment apparatuses include a combustion oxidation apparatus, a biological treatment apparatus In the regenerative type combustion apparatus, the regenerative burner is installed in the combustor to heat the incoming VOC, and the oxidized VOC is discharged to the outlet , It absorbs 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 discharge duct 8 is formed on one side of the inlet duct 7 and a gas discharge hole 9 is formed on the upper side and the discharge port 10 is formed on both sides A hollow shaft 12 having an inlet hole 11 is communicated below the center of the air-direction switching rotary part 3 and a hollow shaft 12 is connected to the hollow shaft 12 via a drive motor 15 and a pulley 13, A chain 14 is provided to rotate the air-direction switching rotary part 3 while the chamber 5 is provided with a twelfth minute partition plate 16 and a partition plate 17 is provided on the partition plate 16, A catalytic plate 18 and a heat accumulating plate 19 are sequentially installed and a burner 20 is installed on one side of a combustion chamber 6 installed on the upper part of the chamber 5 The VOC gas flowing through the twelve equalized blowball plates 16 flows into the chamber 5 and flows into the combustion chamber 6 through the catalyst plate 18 and the heat storage plate 19 and is supplied to the burner 20 The gas of the harmful component is burned and oxidized and discharged through the discharge duct 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 rotary valve assembly for a regenerative thermal oxidation system is provided with a combustion chamber 6 on the upper side inside the regenerative combustion section 1, 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 at an upper side facing the inflow duct 7, A push rod 22 is provided on the guide fixing shaft 21 on the lower side of the shaft 12 and the push rod 22 is connected to the air cylinder 24. The air cylinder 24 is connected to the driving motor 20 And the rotation wheel 23 is rotationally driven via 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) in which a latch gear (not shown) having one tooth is engaged by the operation of the air cylinder 24 while being rotated forward and backward while being switched to reciprocating motion, The hollow shaft 12 provided on the upper side of the hollow shaft 12 is rotated so that the rotor 3 is rotated at a predetermined angle to supply the noxious gas, .

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.
