Pressure buffer device and regenerative combustion type exhaust gas treatment device including the pressure buffer device

Abstract

The invention provides a pressure buffering device which can effectively absorb fluid pressure change generated in a pipe under the action of a treating device without increasing the pressure loss of the pipe connecting a fluid supply source to the treating device for treating the fluid. Besides, the invention provides a regenerative combustion type waste gas treating device which comprises the pressure buffering device and inhibits the increase of operation cost and the integral large size of equipment. The pressure buffering device comprises a chamber having a certain volume and including an inlet pipe and an output pipe at two ends; and perforation plates dividing the interior of the chamber into a plurality of spaces and having a plurality of punching holes or screen holes formed thereon. The interior of the chamber is divided into a plurality of pressure buffering chambers by the perforation plates arranged at specified intervals relative to the flowing direction of fluid, and pressure detecting elements for detecting inner pressures of the pressure buffering chambers are arranged in the central pressure buffering chambers other than the pressure chamber at the most upstream side and the pressure chamber at the most downstream side in the flowing direction of the fluid. The pressure buffering device is preferred to be arranged in the regenerative combustion type waste gas treating device as an example of treading devices.

Description

technical field [0001] The invention relates to a pressure buffer device arranged between a pipeline connecting a fluid supply source and a treatment device for treating the fluid, and a thermal storage combustion waste gas treatment device comprising the pressure buffer device. Background technique [0002] Exhaust gas containing volatile organic compounds (V°C) from painting factories etc. is subject to emission restrictions. In these plants, when decomposing exhaust gas containing VOCs, for example, using Image 6 The shown regenerative combustion type exhaust gas treatment device 1' (for example, refer to Patent Document 1). [0003] The above-mentioned regenerative combustion type exhaust gas treatment device 1' is composed of a combustion chamber 3, three regenerator chambers (5A, 5B, 5C), a gas to be treated supply pipe 7 (gas to be treated supply flow path), a gas to be treated exhaust pipe 8 ( Process gas exhaust flow path) and purge gas extraction pipe 9 (purge ga...

Problems solved by technology

[0016] However, in the former method, since a large pressure loss occurs in the duct, a fan with a large power is required, which has the problem of increasing power consumption.

In addition, for the latter of the above-mentioned methods, since the gas to be processed is diluted by using the atmosphere, the processing amount of the gas to be processed will increase, resulting in the combustion chamber 3, regenerators 5A, 5B, 5C As a result of the increase in scale of ancillary equipment such as
