Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment control system. Background Art

[0002] During production, waste gas is generated in each workshop, and the waste gas must be centrally collected and then centrally treated before it can be discharged into the atmosphere after meeting the national emission standards. However, due to some factors as follows, the waste gas needs to be frequently started and stopped manually; for example, although constant-speed long-term operation does not require manual intervention and can save labor, it still operates during non-production and production intervals, resulting in a large amount of energy consumption waste. Therefore, the utility model provides a waste gas treatment control system. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a waste gas treatment control system, which can make the waste gas treatment equipment start and stop synchronously with the production equipment without manual intervention, and when only one of the two workshops is operating, automatically reduce the operating speed of the waste gas treatment equipment and synchronously close the pipeline valves of some non-producing workshops, so as to ensure that the waste gas is treated while fully saving energy.

[0004] The utility model realizes the above purpose through the following technical scheme: a waste gas treatment control system, including an air duct connecting the air outlets of the DT workshop and the CP workshop, a waste gas treatment equipment connected to the air duct, an air outlet pipe connected to the air outlet of the waste gas treatment equipment, and a chimney connected to the air outlet pipe. The waste gas treatment equipment is connected with a linkage control device, and the linkage control device includes a CP operation relay, a DT operation relay, a frequency converter controller, and a processing equipment relay. The normally open point of the CP operation relay is connected to the input end L1 of the frequency converter controller through a signal wire, the DT operation relay is connected to the input end L2 on the frequency converter controller, one end of the processing equipment relay is connected to the frequency conversion output point of the frequency converter controller through a signal wire, and the other end is connected to the 24V input point.

[0005] Preferably, the waste gas treatment equipment sequentially includes a filtering section, a photocatalytic section, an adsorption section, and a fan section.

[0006] Preferably, an electromagnetic valve is arranged in the air duct of the CP workshop, and the on-off switch of the electromagnetic valve is connected to the output point Q1 on the frequency converter controller through a signal wire.

[0007] Preferably, the frequency conversion output points include a first-stage speed output point D1 and a second-stage speed output point D2. One end of the processing equipment relay is respectively connected with a first-stage speed relay and a second-stage speed relay, and one ends of the first-stage speed relay and the second-stage speed relay are respectively connected to the first-stage speed output point D1 and the second-stage speed output point D2.

[0008] The beneficial effects of the technical solution of the present utility model are as follows: The CP operation relay and the DT operation relay are respectively connected to L1 and L2 on the frequency conversion controller. The first-stage speed output point D1 and the second-stage speed output point D2 on the frequency conversion controller are both connected to the processing equipment relay. When the CP workshop enters production, a startup signal is sent from L1 to the frequency conversion controller. The frequency conversion controller issues a first-stage speed operation instruction through D1 and controls the waste gas treatment equipment to operate at the first-stage speed through the first-stage speed relay and the processing equipment relay. When the CP workshop and the DT workshop are producing simultaneously, the waste gas treatment equipment operates at the first-stage speed. When the CP workshop stops running, the DT workshop runs. The CP operation relay sends a shutdown signal to L1, and Q1 sends a signal to the on-off switch of the solenoid valve. The solenoid valve closes. At this time, the waste gas treatment equipment operates at a reduced speed in the second-stage speed, thereby reducing energy consumption and improving economic benefits. The system can make the waste gas treatment equipment start and stop synchronously with the start and stop of the workshop production line without manual intervention. When a workshop stops production, the running speed of the waste gas treatment equipment is automatically adjusted, thereby reducing energy consumption and improving economic benefits.

The exhaust gas treatment device is connected with a linkage control device, and the linkage control device includes a CP operation relay 8, a DT operation relay 9, a frequency converter controller 10, and a treatment device relay 11. The normally open point of the CP operation relay 8 is connected to the input terminal L1 of the frequency converter controller 10 through a signal line. The DT operation relay 9 is connected to the input terminal L2 on the frequency converter controller 10. One end of the treatment device relay 11 is connected to the frequency conversion output point of the frequency converter controller 10 through a signal line, and the other end is connected to the 24V input point.

[0017] An electromagnetic valve is provided in the air duct 1 of the CP workshop, and the on-off switch of the electromagnetic valve is connected to the output point Q1 on the frequency converter controller 10 through a signal line.

[0018] The frequency conversion output points include a first-stage speed output point D1 and a second-stage speed output point D2. One end of the treatment device relay 11 is respectively connected with a first-stage speed relay 13 and a second-stage speed relay 14.
