Description

Technical Field

[0001] The utility model belongs to the technical field of waste gas monitoring equipment in petrochemical industry, and particularly relates to a waste gas monitoring device in petrochemical industry. Background Art

[0002] Petrochemical waste gas can be divided into oil refining waste gas, chemical waste gas, synthetic fiber waste gas and petrochemical fertilizer waste gas; harmful components include combustion smoke, dust, sulfur dioxide, nitrogen oxides, etc. The waste gas monitoring device can monitor the exhaust gas to avoid directly discharging the excessive waste gas into the air. The excessive waste gas should be temporarily stored, so it is necessary to propose a petrochemical waste gas monitoring device.

[0003] For example, a Chinese patent with publication number CN218481498U discloses a wastewater and waste gas monitoring device for petrochemical industry. The patent sets a touch switch and a detection probe. When it is necessary to detect the wastewater, the connecting water pipe is connected to the outlet pipe through the connecting flange. Due to the setting of the solenoid valve, the wastewater flows into the water distribution pipe through the connecting water pipe, and flows into the detection bottle through the water distribution pipe. At this time, under the influence of water buoyancy, the float is driven to move up, and the sliding rod on it is driven to slide in the limit slide. When the limit slide moves to the upper part, the float blocks the water distribution pipe and presses the touch switch. The touch switch transmits an electrical signal to the control center through the line, and the control center transmits the electrical signal to the detection probe to detect the water inside the detection bottle. If the water passes the detection, the control center opens the solenoid valve through the electrical signal, and the water can flow out through the connecting water pipe. If it passes the detection, the control center activates the alarm through the electrical signal, and the alarm sounds an alarm to inform the staff. The detection is very convenient and does not require manual operation.

[0004] Although this patent improves the convenience of waste gas monitoring in petrochemical industry, this patent still has some structural deficiencies. For example, the buoyancy of the float in the waste water is used to push the sliding rod to push the touch switch to start a test, which makes the real-time performance of the detection equipment poor and leads to insufficient continuity of the detection data. At the same time, the waste gas and waste water in the connected water pipe are diverted to the detection bottle through the water distribution pipe. The detection probe in the detection bottle detects the waste gas and waste water. In actual use, it is necessary to operate the detection bottle to pour out the waste gas and waste water after each test, which makes the monitoring device inconvenient to use. Utility Model Content
