Description

Technical Field

[0001] This utility model relates to the technical field of dust collector components, and in particular to the technical field of insulator chamber heating and dehumidification devices. Background Technology

[0002] During the operation of a wet electrostatic precipitator, the porcelain bushings inside and outside the insulator chamber must be kept dry. If moisture from inside the electric field enters the insulator chamber, causing a large amount of water to accumulate on the surface of the porcelain bushings, it can lead to creepage. In severe cases, it may cause the porcelain bushings to break down, resulting in a short circuit inside the power plant. In the electrostatic precipitator system, dust particles become charged in the high-voltage electric field and will deposit on the surface of the insulators, leading to reduced insulator performance and even equipment failure. Therefore, electrostatic precipitator insulators often require heating control to ensure stable equipment operation. Thus, it is necessary to design an insulator chamber heating and dehumidification device. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a heating and dehumidifying device for insulator chambers. This device can heat and dehumidify the porcelain bushings and blow away dust from the top, so that the internal environment of the main body of the insulator chamber is dry and dust-free, which is conducive to ensuring the stable operation of the equipment.

[0004] To achieve the above objectives, this utility model proposes an insulator chamber heating and dehumidification device, comprising an insulator chamber body, a porcelain sleeve, an inner heating rod, an air guide pipe, an air inlet, a dehumidifying filter, a dust filter, an air pump, an air blowing groove, a purge groove, and air blowing holes. The porcelain sleeve is installed inside the insulator chamber body, and the inner heating rod is inserted through the bottom of the porcelain sleeve. An air guide pipe is installed on the side of the insulator chamber body, with an air inlet at the bottom end of the air guide pipe. A dehumidifying filter and a dust filter are connected within the air guide pipe. The top end of the air guide pipe is connected to the air inlet of the air pump, which is located on the top of the insulator chamber body. An air blowing groove is connected to the exhaust end of the air pump. A purge groove is located at the bottom of the air blowing groove, facing the porcelain sleeve, and several air blowing holes connected to the air pump are located within the purge groove.

[0005] Preferably, an insulating elastic washer is fitted at the bottom of the porcelain bushing. The insulating elastic washer is a sealing rubber washer, and the insulating elastic washer is sealed between the bottom of the porcelain bushing and the connection gap between the insulator chamber body and the porcelain bushing.

[0006] Preferably, the dehumidifying filter is located at the front end of the dust filter, and the dehumidifying filter and the dust filter are detachably installed in the air duct.

[0007] Preferably, an airflow sensor is installed inside the air duct, the airflow sensor is connected to the air pump, and the air pump is equipped with an audible and visual alarm.

[0008] Preferably, the air-blowing sleeve is a high thermal conductivity sleeve, and a heating sleeve is fitted on the outer side of the air-blowing sleeve.

After experimental optimization, the internal heating rod and air blowing sleeve groove heat and dehumidify the porcelain sleeve and blow dust from the top. The generated hot and humid dust-laden airflow is drawn away from the porcelain sleeve by the air pump. At the same time, the airflow is dehumidified and dusted by the dehumidifying filter and dust filter. The continuous circulation of airflow dehumidifies and removes dust, making the internal environment of the insulator chamber dry and dust-free, which helps to ensure the stable operation of the equipment.
