なければならない欠点がある。Each of the conventional abatement systems mentioned above is dedicated to a specific type of waste gas, and in production plants where various types of waste gas are emitted together, one type of abatement device cannot perform complete abatement treatment. There is a drawback. For example, if waste gas containing powder flows into an acid or alkaline waste gas abatement device through gas-liquid contact with a perforated plate, the perforated plate in the device will become clogged with powder, reducing processing capacity. There is a drawback that the abatement equipment must be stopped and regeneration work must be carried out.

Each damper 20.21, 22.23 is an electric damper, and their activation signals are outputted from a sequencer 29. On the other hand, the regeneration period can be monitored using the differential pressure between the upper and lower parts of the white base 12.
40 Check the clogging condition. When the perforated plate becomes clogged, the differential pressure between the upper and lower parts of the inner column increases. This is read by the differential pressure gauge 28, and if it exceeds the set pressure, a signal is sent to the sequencer 29 to each damper 20.21, 22.23. Activate the damper as shown in the table and perform regeneration. Regeneration is carried out for a predetermined time using a timer built into the sequencer 29, and then the damper is activated to return to the normal $ state.
