Abstract

This invention is to provide a rotary gas adsorption concentration device which can use high-temperature air to desorb volatile organic compound (VOC). According to the present invention, a sealant is made of an inorganic heat-resistant material; a channel is formed in a contact surface of the sealant with a honeycomb rotor. An air bank is formed by the space of the channel. The heat conductivity is reduced, and the transmission of the heat of a desorption zone to an adsorption zone is reduced. In this way, even when the temperature of the desorption air is increased, the temperature of the adsorption zone is not elevated to maintain an adsorption performance.

[Technical field to which the invention belongs] The present invention relates to a kind of organic gas containing high Buddha point (VQq > treatment. Rotary gas adsorption and concentration device, which can effectively adsorb and condense the gas [prior art] ... ? Rotary gas adsorption concentration device is used to treat the complex absorption in the air. ^ You Tξ: For the large amount of organic solvents (paints and inks) released from spraying plants and printing plants ( V0C), in order to prevent the pollution of the environment, these m: pollution-free combustion treatment1 save energy: it is necessary to reduce the volume of the gas being burned, it is necessary to first condense the voc 孀 to increase its concentration while reducing The volume of the gas to be processed. For this reason, a rotary gas adsorption concentrating device using a honeycomb-shaped turntable supporting a sorbent has spread rapidly. As described above, a rotary gas adsorption concentrating device uses a honeycomb supporting a sorbent. The turntable is divided into an adsorption zone and a desorption zone, and the air to be treated containing VOC is inputted in the adsorption zone, and the honeycomb-shaped turntable is adsorbed in the desorption zone. For vOC desorption, high-temperature desorption air is used to purge it. The above-mentioned sealing technology that separates the adsorption area and the desorption area has been disclosed in Japanese Patent Application No. 2536860. In semiconductor factories, a variety of vocabularies are used. Among these used vocs, they contain organic gases with a boiling point of more than 200 ° C. At the same time, there are also polymerizations caused by V0C adsorbed on a honeycomb turntable. Its boiling point rises. Desorbed air of about 160-180 ° C is sent to the desorption area, and it is absorbed in the bees.

The V0C on the high boiling point V0C nested turntable described on the 1J face was desorbed and immediately gathered on the turntable. To this end, it is necessary to further increase the warm production of desorbed air, which is disclosed in Xu Bulletin No. 20 bu 27855 1. According to this hang: T said Bente and other non-combustible materials constitute dense airtightness to ensure the air tightness of each section, high temperature desorption air above 彳 4 graphite 3 ο 〇r, can also be desorbed * ,; bucket 'can transport w 1 pay Voc of the boiling point [Abstract] The problem to be solved by the invention is the above technology, which relies on the airtightness of a rod-shaped seal such as graphite. For this reason, there is a sealing problem caused by the increase in the temperature of the desorption air to ensure that the temperature of the materials in each section rises, resulting in the heat direction of the desorption air. ",,,, and the inside of the adsorption area is asked. The rotary gas provided by the present invention is adsorbed by the desorption air at a temperature higher than ° C to desorb. V0C, at the same time, the heat of the desorbed air is difficult to transfer to the problem to be solved by the invention on the suction-shaped turntable, the honeycomb-shaped turntable gas retention zone, and the guide area.

In order to solve the above-mentioned problem, the present invention is provided with a groove on the contact surface of the seal, and the space in the groove is formed to cause an external thermal conductivity to be reduced, and the heat in the desorption region is rarely transmitted. And ^ [Embodiment] The rotary gas adsorption concentration provided by the present invention is

The non-contact surface of the rotary driving load suction and suction area is provided with resistance, and also has a preventive effect. The sealing material of the charged honeycomb-like rebirth, the groove 'is due to the groove to stop the desorption of hot air, and the turntable has a desorption area that is separated from the space inside the honeycomb-like turntable to improve its insulation. Examples in which the amount is transferred from the desorption zone to the adsorption zone The gas and works of the invention are described in detail below with reference to the drawings of the present invention.

And a sectional view of its mounting portion. Sealing material for U 4 type rolling body concentrator. This type of integrated mica is an I.f. sealing material (1) is an integrated mica. The mica sheet is bonded with a fat adhesive on the bottom surface 2 and 2 of the sealing material 1.上 Forming a trench 4. Furthermore, the 3 corners where the end faces of the honeycomb turntable contact are cut off to form chamfers 5 and 6. The bottom surface 2 and the side surfaces of the chamfering seal material are formed in a white < direction, and are formed on the upstream side. The moving side 7 of 6 and 6 with respect to the honeycomb turntable 3 is a spring, according to which the pressure can be pressed by the nut 8 ▲ on Tuesday, f material 1 on the honeycomb turntable 3. The head of the plug 9 is located in the groove 41. The nut 8 and the bolt 9 are screwed together. The bolt 9 is made from-to ί = and penetrates through the sealing material 1. The bolts 12 are mounted on the + gold mold 12 and the L metal mold 13, and are pressed against the bee ^. That is, the sealing material 1 is mounted on the frame and raised. On the isolated turntable, the sealing material 1 is elongated as shown in FIG. 2 when receiving the elastic force of the spring 7 as shown in the figure.

The periphery of the nest-shaped turntable 3 like the desorption area 14 is arranged in an oblique V shape in a circular arc shape, and is arranged along the honeycomb 14. Material 15 forms a fan-shaped desorption area. The present invention thus constituted ~ While the nest-shaped turntable rotates, the two-type gas adsorption concentration device is in the processing area of the bee. The air in the treated air is adsorbed by the adsorbent input on the bee-shaped turntable turntable, and ^ f's 0 (organic solvent) is attached by the bee-like air to desorb and is adsorbed. When the area depletes the desorbed air of about 18 ° C, the concentration of animal vocal vocabulary is condensed to 1 / 10th of the place where the empty milk is placed. Because the sealing material is 10 times the gas. The desorption air is connected to the groove 4 by connecting the end faces of the hand-wort-shaped turntable from the desorption area 14 together with the spring: use: and the bottom surface of the sealing material 1 is designed with a groove due to the poor sealing material 彳Use even more to prevent this leakage. The heat of the desorption zone 14 is difficult to form air retention, and the thermal conductivity is changed. The heat of the treated air is very small and is transmitted elsewhere. Therefore, it passes from the desorption area 14 to the end of the honeycomb turntable 'bend: without degrading the adsorption performance. When the sealing material 1 shown is moved up and down, and the rotary shaft is inclined, it can be freely folded as shown in the figure to resist impeachment. f means that the sealing material 1 decreases with the bolt Θ force. The% ^ of the spring 7 will rise when the spring force is reached, and it will be adjusted according to the spring 7 spring. The integrated vowel can be peeled off by the nut 8 screwed with the bolt 9 and the sealing material 1 in the moving direction, forming a reverse on the upper side, relative to the movement of the honeycomb turntable 3. And 6, thereby preventing the formation of a sealing material
