Description

Technical Field

[0001] This utility model relates to the field of industrial production, and more particularly to the field of intelligent leak detection, specifically referring to a device for intelligent dust removal based on an industrial environment dust removal system. Background Technology

[0002] In industrial production processes, the pressure difference of filter bags in industrial dust collection systems changes dynamically, but the pulse jet cleaning pressure is often set to a fixed value. Excessive pulse jet cleaning pressure wastes compressed air and shortens the filter bag's lifespan, while insufficient pressure fails to achieve efficient dust removal. When a leak occurs in the pulse jet cleaning system, dust-laden gas is discharged untreated to the system's outlet. Currently, leak detection is often based on manual experience to assess the ash content of the exhaust gas, which is highly inefficient. Furthermore, identifying a leak requires opening all compartment covers and manually observing the ash accumulation at all pulse valve locations, wasting significant manpower and resources. Downtime also disrupts normal production, resulting in substantial losses. Utility Model Content

[0039] In a specific embodiment of this utility model, a device for intelligent dust removal based on an industrial dust collection system is disclosed. The device includes a pulse jet cleaning structure and a lift-up leak detection structure. The pulse jet cleaning structure comprises a compressed air storage tank 1, a compressed air delivery pipe 2, a pulse jet valve 3, and a filter bag 4. The lift-up leak detection structure comprises a particulate matter concentration monitor 5, a leak detection signal transmission line 6, and an electric lift valve 7. The outlet end of the compressed air storage tank 1 is connected to the compressed air delivery pipe 2, the outlet end of the compressed air delivery pipe 2 is connected to the pulse jet valve 3, the outlet end of the pulse jet valve 3 is connected to the filter bag 4, the signal outlet end of the particulate matter concentration monitor 5 is connected to the leak detection signal transmission line 6, and the outlet end of the leak detection signal transmission line 6 is connected to the electric lift valve 7. This utility model's lift-up leak detection structure has a high degree of intelligence, enabling precise fault location and early risk management during the dust removal process.

[0040] The compressed air tank consists of one unit with an inlet pressure of 0.7–0.8 MPa and an outlet pressure of 0.4–0.5 MPa.

[0041] There are 30 pulse jet valves 3, evenly distributed in the three compartments of the environmental dust removal system, 10 valves in each compartment, installed at staggered heights. Each compartment includes an air distribution manifold 31, a differential pressure sensor 32, and a Venturi jet pipe 33. The pulse jet pipe has a pulse width of 0.1s and a jet interval of 10s. The air distribution manifold 31 has a volume of 1600L, an inlet pressure of 0.4–0.5MPa, and outlet pressures of 0.2MPa, 0.3MPa, and 0.4MPa, providing three pulse jet pressure levels. The differential pressure sensor 32 senses changes in the filter bag filtration differential pressure at three levels: low pressure <1000Pa, medium pressure 1000Pa–1400Pa, and high pressure >1400Pa. The Venturi jet pipe 33 has 30 nozzles corresponding to 30 filter bags 4, with the nozzles 200mm away from the filter bags.

[0042] The filter bags number 4, totaling 900 bags, have a total air volume of 200,000 m³ / h. They are made of polytetrafluoroethylene (PTFE), with a bottom diameter of 160 mm and a body length of 8,000 mm.

[0043] The particulate matter concentration monitor 5 has one signal and is installed in the environment except for the outlet pipe. It measures the particulate matter concentration within a 10-second interval between each pulse jet valve 3.

[0044] There are 3 electric lifting valves 7, which are evenly distributed in the 3 compartments of the environmental dust removal system. They are installed at the outlet end of each compartment and the opening degree is adjustable from 0 to 100%. They are generally set to three opening degrees: 0%, 50%, and 100%.

[0045] The compressed air storage tank 1 receives high-pressure compressed air (0.7-0.8 MPa) from the factory, reduces the pressure to 0.4-0.5 MPa, and delivers it to the air distribution manifold 31 of the pulse jet valve 3 through the compressed air delivery pipe 2. The air distribution manifold 31 of the pulse jet valve 3 senses the filter bag filtration pressure difference (low pressure <1000 Pa, medium pressure 1000 Pa-1400 Pa, high pressure >1400 Pa) through the differential pressure sensor 32, and provides pulse valve jet pressures of 0.2 MPa, 0.3 MPa, and 0.4 MPa respectively.

[0046] The pulse jet pipes are installed at staggered heights to maximize space utilization. The pulse width is 0.1s and the interval between pulses is 10s. Through pulse jet cleaning, an induced airflow is generated, causing the filter bag 4 to rapidly expand and shrink back. During the expansion and shrinkage process, the accumulated dust on the filter bag will fall off, completing the dust removal.

[0047] The particulate matter concentration monitor 5 measures the particulate matter concentration in the environment, excluding the outlet pipeline, within a 10-second interval between each pulse jet valve 3. When the particulate matter concentration is ≥8 mg / m³, the concentration is measured. 3 At that time, the leak was accurately located in filter bag 4 (corresponding to the pulse valve). An alarm signal and location information were sent to notify maintenance personnel to intervene promptly.

[0048] Specifically, when the particulate matter concentration in the same compartment is ≥8 mg / m³ within a 10-second interval between two pulse valves blowing air, 3 At that time, if any of the corresponding 60 filter bags 4 have leaks, then 20% of the filter bags 4 are at risk of leakage. The particulate matter concentration monitor 5 signal is connected to the leak detection signal transmission line 6, and the opening of the electric lifting valve 7 is adjusted from 100% to 50% to proactively prevent the risk of exceeding environmental emission standards.
