Description

Combined structure of float glass kiln and natural gas hydrogen production conversion pipe Technical Field The utility model belongs to the field of glass kilns, and particularly relates to a combined structure of a float glass kiln and a natural gas hydrogen production conversion tube. Background In the float glass production process, the batch is melted, clarified and cooled at high temperature (relatively high temperature) and then enters a tin bath for forming, and is cooled by an annealing kiln (relatively low temperature). In the actual production process, the batch materials after being fully absorbed and melted in the melting part of the melting furnace form glass liquid, and the glass liquid is circulated in the melting furnace for a plurality of times. Wherein part of the glass liquid passes through the neck and reaches the cooling part to be cooled and lowered. The cooling part in the glass kiln is usually cooled by using a cooling fan to blow lower air through a cooling air pipe to blow the molten glass directly to take away the heat of the molten glass body, so as to achieve the purpose of cooling. In the production of different types of glass, there are often different requirements on the temperature of the glass liquid entering the cooling section for cooling. The upper layer glass liquid, the middle layer glass liquid and the lower layer glass liquid of the cooling part of the melting furnace can be cooled unevenly by the cooling fan, so that the cooling rate is too high when cooling air contacts the uppermost layer glass liquid, the temperature of the upper layer glass liquid is reduced, the density is increased and sunk, and the temperature of the middle layer glass liquid is higher than that of the upper layer glass liquid, thereby forming a heat shower and affecting the normal production process. Conventionally, fossil fuels such as natural gas, heavy oil, coal tar and the like are mainly used in glass melting furnaces, wherein hydrogen produced by a natural gas hydrogen production device can be mixed with natural gas to form a mixed fuel, so that dependence on the traditional fossil fuels is reduced, carbon emission can be remarkably reduced, and meanwhile, the combustion efficiency of the natural gas is improved. In the existing natural gas hydrogen production equipment, the natural gas and steam reforming pyrolysis hydrogen production needs to be subjected to heat acceleration reaction, the heat provided by external natural gas combustion in actual production firstly provides catalytic kinetic energy for mixed gas of natural gas and steam, then after main reaction, the burnt natural gas flue gas gradually enters a preheating section to supplement water and preheat a boiler for producing steam, the combustion gas is preheated, the mixed gas of the natural gas and the steam is preheated, the flue gas is finally discharged to an atmosphere through a chimney after passing through the preheating section, the temperature is always kept at about 180-280 ℃, and the conditions of energy waste and large natural gas quantity required by combustion heat supply exist.
