All electric melting insulator glass furnace

Abstract

The invention discloses an all electric melting insulator glass furnace, comprising a molten pool (11), an allocation pool (6) and a feed path (7), wherein, the molten pool is mainly composed of an external wall (3), an insulating layer (4), a lining (5), a furnace top (8) and a furnace bottom (10); the lower part of the molten pool is connected with the allocation pool by a liquid flowing opening (9) and an upper liquid flowing path (12); the allocation pool is connected with the feed path; a charging opening (1) is arranged above the molten pool; electrodes (2) are respectively arranged in the molten pool, the liquid flowing opening, the upper liquid flowing path and the allocation pool at intervals; and the molten pool is vertically arranged, and the cross section of the inner cavity of the molten pool (11) is of an annular regular hexagon structure. The glass furnace does not generate toxic and harmful gas and dust pollution, is favorable for environment protection, and achieves quick, even and pollution-free melting state, thus improving quality such as insulating properties, mechanical strength and the like of a glass insulator, improving the melting rate of a melting furnace, lowering production cost, increasing economic benefit, and being more favourable for environment protection.

Description

technical field [0001] The invention relates to a glass furnace, in particular to a tempered glass insulator glass furnace. Background technique [0002] As we all know, glass insulators are widely used in the power industry because of their good self-cleaning properties, not easy to age, high insulation performance, high mechanical strength and zero-value self-breakage. At present, manufacturers of glass insulators generally use fuel (gas) regenerative horseshoe flame glass furnaces to melt glass raw materials for the production of glass insulators to form glass liquid to produce glass insulators. Fuel (gas) regenerative horseshoe flame glass furnaces Although it has the advantages of long flame, relatively complete combustion, low investment, low energy consumption and easy operation, the fuel (gas) regenerative horseshoe flame glass furnace has the following problems: First, a large amount of gas will be generated during the combustion process.

At present, manufacturers of glass insulators generally use fuel (gas) regenerative horseshoe flame glass furnaces to melt glass raw materials for the production of glass insulators to form glass liquid to produce glass insulators. Fuel (gas) regenerative horseshoe flame glass furnaces Although it has the advantages of long flame, relatively complete combustion, low investment, low energy consumption and easy operation, the fuel (gas) regenerative horseshoe flame glass furnace has the following problems: First, a large amount of gas will be generated during the combustion process. Toxic and harmful gases such as sulfur dioxide and carbon monoxide will bring serious pollution to the atmosphere and damage human health and ecological balance; secondly, due to the need to maintain a slight positive pressure inside the fuel (gas) regenerative horseshoe flame glass furnace, during the production process A lot of light glass raw materials will volatilize with the flue gas into the atmosphere to form dust pollution. This kind of dust is usually too small to be distinguished by the naked eye. It is the direct cause of occupational diseases and silicosis in the glass industry; the third is the fuel (gas) regenerative horseshoe flame The refractory material in the glass kiln is corroded by the high-temperature glass liquid, causing the surface layer to fall off, corrode, and severely damaged. The shed refractory material and the high-temperature glass liquid form stones, resulting in a large amount of waste products, and the product loss ratio is as high as 10-30%. And produce potential quality hidden dangers, shorten the life cycle of the glass furnace, and increase the production and operation cost of the glass furnace; There are reasons such as changes from time to time, the temperature in the kiln is not uniform, and the thermal system is always unstable, which will directly affect the quality performance of the produced glass insulators in terms of insulation performance and mechanical strength.
