Novel self-cooling electrode applied to industrial burner

Abstract

The invention relates to a novel self-cooling electrode applied to an industrial burner. The electrode comprises an electrode body and the burner used for installing the electrode body, wherein the electrode body comprises an electrode head, an electrode shell, an O-shaped ring, an electrode clamping sleeve, an extension electrode wire, a ceramic tube, a conversion joint and an adjusting nut. Theburner is also provided with a cooling inner cavity, the other end of the ceramic tube is inserted into the cooling inner cavity, and the other end of the extension electrode wire penetrates through the cooling inner cavity and enters an ignition position of the burner. The electrode adopts an integral insulated electrode shell and is provided with an air connection port, so that equipment and personnel are effectively protected when the ignition and detection performance is ensured, the service life of the equipment or devices is prolonged, and the self-cooling electrode is universal for different burners.

Description

technical field [0001] The invention relates to the field of industrial electrodes, in particular to a novel self-cooling electrode applied to industrial burners. Background technique [0002] In the heating process of contemporary industrial production, the burner is an indispensable part of the thermal standby. Such as Figure 7 As shown, the industrial electrodes used for ignition and detection on the existing burner generally include an electrode head 1', an electrode wire 2', an electrode ferrule 3' and a ceramic tube 4'. However, when the above-mentioned electrodes are installed on the burner, some electrode wires will be exposed between the ceramic tube and the electrode, and when ignition occurs, the part of the burner shell that is close to the electrode tip will ignite, causing potential safety hazards. At the same time, after a long time of use, the electrode wire will undergo stress deformation in a high-temperature environment, which will cause the position of ...

AI Technical Summary

Problems solved by technology

However, when the above electrode is installed on the burner, part of the electrode wire will be exposed between the ceramic tube and the electrode. When ignition occurs, it will ignite near the electrode tip, that is, the part of the burner shell, causing a safety hazard.

At the same time, after a long time of use, the electrode wire will undergo stress deformation in a high-temperature environment, which will cause the position of the ignition end of the electrode wire to shift, greatly reducing the success rate of ignition
