Gas igniter integrated device

Abstract

The invention provides a gas igniter integrated device. The gas igniter integrated device comprises a transformer sleeve, a gas pipe connected with the transformer sleeve and a casing pipe connected with one side of the gas pipe and further comprises an automatic ignition device, an ignition transformer, a flame monitoring device, an input and output port and a programmable logic controller (PLC) control circuit. The automatic ignition device is arranged in the transformer sleeve and connected with the PLC control circuit through the input and output port; and the ignition transformer is arranged in the transformer sleeve, connected with a relay of the automatic ignition device, and controlled by the PLC control circuit. The flame monitoring device is arranged in the casing pipe and composed of three parts including a gas burner, an ignition electrode and an ion electrode, the gas burner is connected with the gas pipe through a valve, the ignition electrode is connected with the ignition transformer, and the ion electrode is connected with the automatic ignition device. The ignition transformer can generate thousands of volts of high voltage, simultaneously a short circuit protective circuit and an open circuit protective circuit are provided; flame is monitored in real time; and the gas igniter integrated device is high temperature resistant, strong acid resistant, oxidation resistant, compact in structure and convenient to use.

Description

technical field [0001] The invention relates to the fields of coking chemical industry and automatic ignition of kilns, in particular to an integrated device of a gas igniter. Background technique [0002] The gas igniter integrated device is the core equipment for the recovery of coking by-product sulfur. Due to its special application environment, there are the following technical problems: [0003] 1. Its extremely harsh working environment of strong acid and high temperature requires the device to have excellent resistance to strong acid and high temperature; [0004] 2. The temperature is high during heating, and in a strong acid environment, the instrumentation equipment is easily oxidized, and the requirements for the equipment itself and its installation are very high; [0005] 3. Ignition transformer is an important equipment of gas ignition device, which requires high reliability and durability when working at high voltage and high temperature; [0006] 4. T...

AI Technical Summary

Problems solved by technology

[0004] 2. The temperature is high during heating, and in a strong acid environment, the instrumentation equipment is easily oxidized, and the requirements for the equipment itself and its installation are very high;

[0007] At present, there is no suitable product of this kind in China, and the price of similar foreign products is extremely expensive. Therefore, in order to save costs, effectively save energy and reduce emissions, it is very necessary to develop a gas igniter integrated device that replaces foreign products.
