Case Study and Customer Feedback on Smart Dust Filter Solution - Petrochemical Industry
Petrochemical safety is always a topic of focus in the industry
In petrochemical enterprises, equipment maintenance has the characteristics of frequent, complex, highly technical, and dangerous repairs compared to other enterprises.
Dangerous energy sources within the maintenance area may cause safety accidents such as energy leakage, fire, or explosion. According to statistics, accidents such as explosions, poisoning, suffocation, falls, and electric shocks that occur in petrochemical enterprises across the country account for over 66% of injuries and fatalities during maintenance. Therefore, it is particularly important to adopt effective safety measures during equipment maintenance.
Solutions to the above-mentioned issues
01
Replace the compressed air tank and intelligent pulse valve with new ones, and use the intelligent pulse valve and intelligent edge hardware independently developed by Xiechang to remotely transmit the real-time working status of the intelligent valve to Xiechang's independently developed "Clean Dust Cloud" big data platform. Through the mobile APP, the "mobile inspection" of the pulse valve can be achieved, allowing the dust collector to be in "palm" mode;
02
Using an information platform to automatically collect sensor detection data, and based on a mobile app to visualize and automate inspections, making the effective energy consumption of equipment visible. The PC end of Clean Dust Cloud completely eliminates the problems of difficult recording, querying, and management of historical operating data of devices, truly realizing the "standardization", "automation", and "unmanned" of device inspection;
03
The automatic alarm function of the "Clean Dust Cloud" mobile app: it alerts immediately upon discovering abnormal equipment operation, hidden dangers, etc., and "actively" pushes information to equipment maintenance personnel, solving the huge production capacity loss problem caused by untimely discovery of hidden dangers and the heavy workload of reporting, summarizing, and analyzing on site, and recovering corresponding economic losses for owners;
Specific cases of intelligent solutions
Case 1
A large state-owned petrochemical group (Shanghai)
A certain petrochemical group: 2 # coal-fired boiler dust collector (16 sets of air tanks+180 valves), belongs to the renovation of an old project
Solution: The customer retains the control system and uses the Xiechang 3-inch submerged intelligent valve (DC24V), pressure transmitter, acquisition cabinet, and clean dust cloud
Implement functions
Palm inspection: real-time detection of pulse valve spraying, response time<5s;
Blowing analysis: Pulse valve spray statistics, unified analysis
Energy consumption analysis: Analyzing the energy consumption of the dust collector's gas source based on the injection volume
Achieve results
Abnormal diagnosis: In June 2022, the backend diagnosis showed abnormal on-site work; After verification, it was found that there was a leak in the on-site compressed air pipeline
Abnormal diagnosis: The pulse valve worked abnormally in October 2022; After verification, it was found that the customer's original control circuit had an abnormal open circuit.
Case 2
A large state-owned petrochemical group (Shanghai)
A certain petrochemical group: Dust collector of 3 and 4 # coal-fired boilers (each with 176 valves), belonging to the renovation of old projects
Solution: The customer retains the control system and uses the Xiechang 3-inch submerged intelligent valve (DC24V), pressure transmitter, acquisition cabinet, and clean dust cloud
Implement functions
Palm inspection: real-time detection of pulse valve spraying, response time<5s;
Blowing analysis: Pulse valve spray statistics, unified analysis
Energy consumption analysis: Analyzing the energy consumption of the dust collector's gas source based on the injection volume
Achieve results
Abnormal diagnosis: In August 2020, the backend diagnosis showed that the pulse valve was working abnormally on site; Verified as on-site air compressor station maintenance
Abnormal diagnosis: Abnormal operation of airbag pressure and pulse valve in December 2020; Verified as customer shutdown for maintenance.
Case 3
A large state-owned petrochemical group (Jiangsu)
