Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic precipitators, and in particular to a temperature regulating device. Background Art

[0002] The top electromagnetic rapping mechanism in the current electrostatic precipitator cathode system is based on the principle that when the coil of the electromagnetic rapper is energized, a magnetic field is generated around the coil, and the rapping rod is lifted by the magnetic force. When it reaches a certain height, the coil is de-energized, the magnetic field disappears, and the rapping rod falls freely under the action of gravity, striking the rapping rod, which transmits the rapping force to the cathode system device inside the electrostatic precipitator, achieving the purpose of rapping and cleaning. The entire electromagnetic rapping mechanism is placed in a top insulation box, and a heater is used to preheat the tapered insulating shaft and pressure insulator to prevent condensation and discharge.

[0003] The existing top electromagnetic vibration mechanism has the following disadvantages:

[0004] (1) Since the lower rapping rod, conical insulating shaft, and upper rapping rod in the top electromagnetic rapping mechanism are assembled into one piece through the upper and lower connecting sleeves, the coaxiality of the assembly cannot be well guaranteed due to deformation during processing and installation as well as hot operation. This results in the loss of rapping force during the rapping transmission process.

[0005] (2) Since the operating temperature of the tapered insulating shaft is within the range of -30-170°C, the existing top electromagnetic vibration mechanism will cause the operating temperature of the equipment to be limited. It is not suitable for operation in high temperature environment conditions.

[0006] (3) The top electromagnetic vibration mechanism needs to be preheated and kept warm. The existing top electromagnetic vibration mechanism needs to be placed in a top insulation box. Since the electromagnetic vibration mechanism requires maintenance and repair, its internal space is large, resulting in a large number of heaters and a large total power. Summary of the Invention
