Problems solved by technology

[0003] Since chemical gases generated during the production process are discharged into the indoor air, in order to avoid cross-contamination of harmful gases mixed with air caused by air convection, exhaust pipes for exhaust are usually installed in the production site to maintain the air in the site. However, it is often necessary to inspect various equipment and indoor conditions to ensure the safety of equipment and personnel. The existing exhaust pipeline inspection and monitoring steps are cumbersome. When faced with the application scenarios of daily inspection and weekly inspection, The inspection process is time-consuming and laborious, which limits the applicability of the exhaust piping system to a certain extent

Embodiment 1

[0033] The installer installs the airflow control valve body in the pipeline assembly through the series pipeline connection pipe section in the pipeline system, in which the switch system is connected between the airflow control valve body and the power supply circuit, and the fan in the monitoring module is used to communicate with the exhaust pipe. The output pipe of the road is vertically connected, and the power supply circuit of the fan is connected with the signal of the WEB server in the monitoring module to complete the installation of the monitoring system and the exhaust pipe system.

[0034] The monitoring module includes network management, fan status monitoring, data collection and real-time transmission. The network management is based on wired connection and wireless connection to connect the output terminals of each monitoring module in the pipeline components. The network management includes a WEB server, and the fan status monitoring includes fan With the cur...

Embodiment 2

[0037] In this embodiment, on the basis of the above, the administrator logs into the system WEB server through a personal computer, wherein the WEB server is connected to each component in the monitoring module, and the administrator can know the online status of the components through the WEB server, and through the WEB The opening and closing components of the terminal server are operated to remotely open and close the airflow control valve body with the switch system. At the same time, in the ventilation state of the exhaust duct, the online status of the fan and the braking power of the fan collected by the current sensor can be retrieved through the WEB server. 1. The pipeline air flow rate collected by the flow monitoring module is used for the administrator to record the current exhaust pipeline operation status, that is, the ventilation condition.

[0038] The inspection module includes debugging and calibration, air inlet inspection, air outlet inspection and data ana...

Embodiment 3

[0040]On the basis of the above, this embodiment relies on the inspectors to collect data from each component during the inspection work period according to the WEB server, and respectively check the air inlet volume, air inlet flow velocity, outlet air volume, outlet air flow velocity, motor online status, The braking power of the motor is recorded, and the recorded data is used as the initial value, and the online status of the exhaust pipeline is obtained by recording the collected data of the exhaust pipeline in a subsequent period of time, and performing comparison and analysis, that is, the online status of the exhaust pipeline. When the pipeline is working, data sampling, comparison and analysis are carried out so that the inspectors can record the data and regularly conduct safety inspections on the operating status of the exhaust pipeline.

Abstract

The invention discloses a real-time monitoring system for an exhaust pipeline, which belongs to the technical field of exhaust systems; it includes a pipeline assembly, a monitoring module, and an inspection module; the pipeline assembly includes several airflow control valve bodies, a switch system, and a flow monitoring module. The control valve body is installed at the intersection of each pipe section in the pipeline system. The airflow control valve body is used to intercept each series pipeline in the pipeline system. The switch system is connected in series with the airflow control valve body. The switch system is used to open and close the airflow control valve body. , the flow monitoring module is set in the hub position of the pipeline system. This kind of exhaust pipeline real-time monitoring system builds an online WEB terminal of the Internet of Things according to the monitoring components arranged in the exhaust pipeline, which is convenient for the administrator to call the exhaust air through the WEB terminal. The monitoring data and control online status of each monitoring component in the pipeline improves the practicability of the system and facilitates the inspection personnel to perform high-frequency maintenance and point inspection of the exhaust system.

Description

technical field [0001] The invention relates to the technical field of exhaust systems, in particular to a real-time monitoring system for exhaust pipelines. Background technique [0002] Exhaust system means that in order to prevent the harmful substances produced in the production process of the equipment from polluting the air of the workshop, the harmful substances are often captured on the spot through the exhaust hood or suction port, and transported to the purification equipment for treatment by pipelines to meet the emission standards After that, it is reused or discharged into the atmosphere; [0003] Since chemical gases generated in the production process are discharged into the indoor air, in order to avoid cross-contamination of harmful gases mixed with air caused by air convection, exhaust pipes for exhaust are usually installed in the production site to maintain the air in the site. However, it is often necessary to inspect various equipment and indoor condit...
