Problems solved by technology

In the invention with application number 201510989155.7, a method and kiln for producing glass are disclosed. Using this invention, powdered glass raw materials can be melted at high temperature in flight state and the waste heat generated by high temperature reaction can be recovered. This kind of glass kiln needs to The two regenerators are used in turn to preheat the oxygen-containing gas and cool the high-temperature waste gas. Two furnaces are used to feed in turn. The inner wall of the outlet pipe at the junction of the material pipe and the feed port is often bonded by molten material, causing blockage, which affects the smooth feeding of glass raw materials
When the feeding is not smooth, it will reduce the amount of raw material feeding, reduce the output, and affect the stability of the kiln working conditions; when the blockage is serious, the feeding cannot be done, and the furnace has to be shut down for maintenance, resulting in great economic losses

Abstract

The invention discloses a dual-furnace type powder flying melting glass kiln, and belongs to the technical field of glass production. The glass kiln is provided with two regenerative chambers for preheating oxygen-containing gas and cooling high-temperature exhaust gas in turn, two smelting furnaces are required for feeding in turn, feeding openings of the smelting furnaces are connected with rawmaterial feed pipes for inputting powdered glass raw materials, and the problems that molten material condensation and bonding always exist on the inner wall of outlet end pipelines at the connectionsbetween the raw material feed pipes and the feeding openings and cause blockage, normal feeding is affected, and the condition has a great impact on production can be relatively and better solved through the technical schemes that a purge gas input port is arranged on a public feed pipe or a raw material feed pipeline, gates are arranged on the feed openings, the raw material feed pipelines are set as mobile feed pipes, and forced feeding devices are arranged on the feeding openings.

Description

technical field [0001] The invention belongs to the technical field of glass production, and in particular relates to a double-furnace glass kiln for melting powdered glass raw materials at high temperature in a flying state. Background technique [0002] In the field of glass production, powdered glass raw materials are dispersed in high-temperature gas and melted to produce glass. The heat and mass transfer speed is very fast, which can reduce energy consumption and production costs. In the invention with application number 201510989155.7, a method and kiln for producing glass are disclosed. Using this invention, powdered glass raw materials can be melted at high temperature in flight state and the waste heat generated by high temperature reaction can be recovered. This kind of glass kiln needs to The two regenerators are used in turn to preheat the oxygen-containing gas and cool the high-temperature waste gas. Two furnaces are used to feed in turn. The inner wall of the ...
