Cylinder-driven regenerative combustion oxidation treatment device

Abstract

The invention relate to the following cylinder-driven regenerative combustion oxidation treatment device. (2n+1) radial fan-shaped spaces are divided into regenerators inside a regenerative combustionchamber that becomes a cylindrical outer casing, and heat storage material is inserted and filled in each corresponding space; in a state where the upper space of the heat storage material is made into a combustion chamber, the inflow of the harmful gas in each of the regenerators, the discharge of the cleaned gas that has been oxidized in the combustion chamber, and the supply of the purified air for the heat storage material are repeatedly performed in an alternating manner. More specifically, the lifting operation of the valve head is performed by means of a hydraulic cylinder by selectively opening and closing the respective passage holes of the bottom surface of each regenerator; a lower body portion of the valve head is enabled to have a circular funnel shape, an annular valve seatwhich can be tightly attached to the funnel body of the valve head in a gas-tight manner is provided in each of the passage holes, and an eccentric adjustment unit that swings the valve head is provided at a portion where the piston rod of the hydraulic cylinder or the valve stem and the valve head connected to the corresponding piston rod are assembled.

Description

technical field [0001] The present invention relates to a cylinder-driven regenerative combustion oxidation treatment device in which harmful gases containing volatile organic compounds (VOCs) etc. are injected into the Combustion chamber, after burning harmful gas in the above-mentioned combustion chamber to form high-temperature clean gas, the above-mentioned clean gas is discharged to the outside through another regenerator to heat the heat storage material of the corresponding regenerator to about 600°C , the inflow path of harmful gas is formed in the heat storage chamber of the heat storage material heated in the above-mentioned manner, and the purified air is supplied through the heat storage material of the remaining heat storage chamber, and this series of air supply and exhaust processes are carried out by means of It is based on the valve unit of the hydraulic cylinder, and the main part of the lower side of the valve head of the above-mentioned valve unit is in the...

Problems solved by technology

[0013] However, in the previous application as mentioned above, in terms of the characteristics of the camshaft drive that makes the valve rods alternately rise and fall by simultaneously rotating the three working cams fixed on one camshaft, the Among the three channel holes on the bottom of the heat chamber, the valve head of one channel hole completely descends and closes the corresponding channel hole before the valve head of the other channel hole rises and begins to open the corresponding channel hole, and there is a flow of supply air and exhaust gas passing through each channel hole There is a problem of collision (collision with each other), so there is a problem that the inflow of harmful gas, the discharge of clean gas, and the supply of clean air cannot be independently and accurately separated from the inside of the corresponding regenerator, and the mixing between gases occurs (phase mixed) problem

[0014] In order to prevent the above-mentioned problems, it is necessary to minimize the time from the valve opening time point (top dead center) to the valve closing time point ( Bottom dead center), in this case, the valve stem descends downward extremely quickly, and causes the valve head to collide with the channel hole relatively strongly, thus not only generating a lot of noise during the opening and closing of the valve , and there is a problem of increasing the risk of harmful gas leakage due to damage to the valve head and passage holes

[0015] On the other hand, in the above-mentioned prior application, the sealing method of making the lower main body part of the valve head into a circular funnel shape so that the outer peripheral surface of the corresponding main body is placed on the inner peripheral surface of the passage hole is applied, which is more effective. To prevent the leakage of harmful gas, but when the central axis of the valve stem is not accurately located in the center of the passage hole, it is difficult to ensure the complete airtight performance between the valve head and the passage hole, and due to the working process of the valve There is a possibility that the position of the valve stem, which is accurately placed in the center of the channel hole, may be slightly deviated due to various external factors imposed in the center, and therefore additional countermeasures and improvement measures for this are required
