Ash cleaning device for industrial kiln

Abstract

The invention relates to an accumulated ash clearing device for an industrial furnace. The accumulated ash clearing device comprises an accumulated ash loosening device for the industrial furnace and a dust suction device for the industrial furnace, wherein the accumulated ash loosening device for the industrial furnace is used for loosening adhesive accumulated ash into granular dust, and the dust suction device for the industrial furnace is used for sucking the granular dust; the accumulated ash loosening device for the industrial furnace comprises a gas source connecting device which is connected to a compressed gas source, a conveying pipe and a vibrating rod, wherein the gas source connecting device communicates with the inlet end of the conveying pipe so as to convey pulse compressed gas to the conveying pipe, and the vibrating rod is connected to the outlet end of the conveying pipe so as to generate axial vibration under the effect of the pulse compressed gas; and the dust suction device for the industrial furnace comprises a dust suction pipe with a dust suction pipe port and a dust outlet pipe port and a first cooling structure used for cooling the dust suction pipe, wherein a compressed gas inlet branch pipe bypasses the pipe wall of the dust suction pipe, and the compressed gas blown out from the compressed gas inlet branch pipe is blown to the dust outlet pipe port so that a negative pressure region can be formed at the position of the dust suction pipe port. The accumulated ash clearing device for the industrial furnace has the advantages that the high-temperature accumulated ash in the furnace can be safely, rapidly and conveniently cleared.

Description

technical field [0001] The present disclosure relates to ash accumulation processing equipment for industrial kilns, and in particular, to an ash accumulation cleaning device for industrial kilns. Background technique [0002] In industrial kilns, such as high-grade electronic glass substrate production kilns, a certain amount of high-temperature smoke and dust will be generated during the combustion process of fuel. These high-temperature smoke and dust are accompanied by various flying materials in the glass melting production process. It flows, falls, and collects into the sediment chamber of the kiln regenerator and the bottom of the flue, thereby forming high-temperature ash deposits; the temperature of high-temperature ash deposits will reach 300-800°C. The ash is firmly bonded together and gradually increases. When it accumulates to a certain extent, it will affect the flow of flue gas and the stability of the glass melting process, and further affect the quality char...

Problems solved by technology

[0004] This cleaning method, first of all, has serious safety hazards such as burns and scalds for the operators entering the sediment chamber and the flue, and even being sucked into the depths of the flue by negative pressure. At the same time, it takes a long time and the labor intensity of the operators is high; secondly After the slag removal door is opened, a large amount of air in the flue will be sucked in, causing serious damage to the melting process in normal production. It has little effect on kilns that do not require combustion quality or require low combustion quality. However, when combustion is required On kilns with very high quality and product quality, such as kilns produced by high-end electronic glass substrates, this method of opening the door to clean up the accumulated dust will have an impact on the melting process system, which will significantly increase the pressure in the kiln. The combustion atmosphere is changed, which in turn changes the process of redox reaction in the kiln glass liquid, which further affects a series of processes in the kiln, such as removing bubbles, melting, and coloring. The quality of glass products shows that Increased point defects, aggravated streaks, color changes, etc. will greatly affect product quality. Therefore, a safe, reliable, time-saving and labor-saving industrial kiln dust cleaning device is provided that does not affect the production process and product quality.
