A wet electrostatic precipitator (ESP) control method, apparatus, electronic equipment, and storage medium are disclosed, relating to the field of flue gas treatment technology. The method includes: real-time acquisition of the turbidity of the discharged wastewater, the pH value of the circulating water, the flow rate of the spray water, and the dust concentration, temperature, and humidity values ​​at the flue gas inlet from the wet ESP; querying a preset parameter mapping table based on the dust concentration, temperature, and humidity values ​​to obtain a set of operating parameters corresponding to the current flue gas conditions, including a target power supply voltage, a target spray frequency, and a target cumulative discharge threshold; and implementing intelligent control based on the acquired values ​​and the set of operating parameters. The intelligent control includes three modes: coordinated correction of water and electricity parameters, coordinated water and electricity safety, and adaptive discharge. Through real-time monitoring and multi-parameter linkage adjustment, dynamic optimization of the power supply voltage, spray frequency, and discharge operation is achieved. Implementing this technical solution improves the stability of the wet ESP.

The present application relates to the technical field of boiler integrated heat supply, and discloses a gas-electric dual-purpose skid-mounted boiler integrated heat supply device, which comprises a heating furnace body, an oil inlet end and an oil outlet end fixedly communicated with the heating furnace body, and a water inlet and a water outlet fixedly communicated with the heating furnace body; a start motor drives a reciprocating screw rod to rotate; a sleeve ring reciprocates along the screw rod shaft; each push ring is driven to synchronously slide up and down along the outer wall of a vertical smoke pipe; the inner edge of the push ring always keeps sliding contact with the outer wall of the smoke pipe; in the process of reciprocating sliding, the push ring can continuously scrape off the scale layer adhered to the outer surface of the vertical smoke pipe, effectively inhibits the accumulation and thickening of the scale on the heat exchange surface of the smoke pipe, thereby avoiding the attenuation of the heat transfer efficiency caused by the increase of the scale layer thermal resistance, keeping the apparent heat transfer coefficient between the vertical smoke pipe and the water medium stable in long-term operation, significantly prolonging the efficient operation period of the heating furnace body under the condition of no cleaning, and reducing the excessive consumption of fuel caused by scaling.

This utility model provides a device for preventing rebound of shotcrete in tunnels, including a main frame, a strong magnetic base, a barrier net, a jacking mechanism, a scraper plate, and hydraulic struts. After the steel arch frame is erected in the tunnel and before concrete spraying, the main frame is attached to the steel arch frame, and the anti-rebound device is attached to the surface of the steel arch frame using the strong magnetic base. Concrete is sprayed by placing the nozzle inside the barrier net, which effectively intercepts rebound particles and prevents the fresh layer from falling off. After spraying, the jacking mechanism pushes the scraper plate to move repeatedly, smoothing the sprayed concrete. This greatly reduces the amount of rebound of the shotcrete, saves concrete usage, reduces construction costs, and improves the construction quality of shotcrete.

The invention relates to the technical field of cleaning equipment operation data analysis, and discloses a cleaning equipment operation data analysis method and system, which can identify the ground type and generate a corresponding environment identifier by acquiring ground reflection light characteristic information. In combination with the ground cleanliness sensor data and the position information of the cleaning equipment, the system can inquire the environment identifier corresponding to the sensor data. On the basis, whether signal fluctuation is caused by environmental reflection characteristics or not is judged by analyzing signal fluctuation characteristics of sensor data according to environmental identification and the signal fluctuation characteristics. The judgment mechanism effectively solves the problem of sensor data misjudgment caused by a high-reflectivity ground material in the prior art.
