Horizontal barrel-shaped closed bottom-blown energy-saving glass melting furnace

Abstract

The invention discloses a horizontal type bucket-shaped closed bottom blowing energy-saving glass furnace, and belongs to glass product manufacturing. The horizontal type bucket-shaped closed bottom blowing energy-saving glass furnace comprises a furnace body, a feeding inlet, a discharging outlet, an oxygen lance, a flue, a bank slope, an observation window, a molten bath and a high-temperature chamber. The horizontal type bucket-shaped closed bottom blowing energy-saving glass furnace is characterized by being formed and supported by a steel structural frame. The horizontal type bucket-shaped closed furnace body is made of lining refractory materials. The large lower part inside the furnace body is the molten bath, and the small upper part inside the furnace body is the high-temperature chamber. The oxygen lance is arranged at the bottom of one end of the furnace body. The feeding inlet is formed in the side wall of the furnace body. The end face of the other end of the furnace body is provided with the discharging outlet and the flue, and the inclined plane bank slope is arranged at the lower portion of the end of the furnace body. The observation window is arranged on the side wall of the high-temperature chamber. Compared with the prior art, the horizontal type bucket-shaped closed bottom blowing energy-saving glass furnace has the advantages of being simple in structure, balanced in stress, safe, reliable, small in size, large in capacity, high in heat efficiency, environmentally friendly, even in ingredient mixing and high in discharging quality, saving energy and the like, and therefore the horizontal type bucket-shaped closed bottom blowing energy-saving glass furnace has the good use and population value.

Description

1. Technical field: [0001] The invention belongs to the manufacture of glass products, in particular to a horizontal drum-shaped closed bottom-blown energy-saving glass melting furnace. 2. Background technology: [0002] The glass product melting furnace under the prior art is mainly a semi-closed long rectangular cubic furnace with one end feeding and one end discharging. The upper part of the furnace is a heating chamber, and the lower part is a glass molten pool. The heating and melting of the glass-making raw materials is realized by the flame spray gun at the feeding end, the oxygen blowing bubbling on the bottom surface of the middle part and the electric heater. This form of furnace has many drawbacks and deficiencies. Mainly include: 1. The glass-making raw materials in the furnace mainly rely on the absorption of radiation and conduction heat energy from the upper heating chamber to melt, while the glass-making raw materials and glass melt are poor conductors, so m...

AI Technical Summary

Problems solved by technology

The provision of more heat sources requires burning more fuel, generating more waste gas and carrying away more heat energy, resulting in energy waste and environmental pollution

2. In order to improve the thermal efficiency, it is necessary to dilute the glass-making raw material and the depth of the glass melt to increase the contact area, resulting in an overly large furnace body and a too shallow molten pool

3. Excessively large molten pool area, excessively shallow glass melt and excessively high temperature heating chamber will cause the loss and difficulty of controlling the easily sublimable materials in the glass-making raw materials, affecting the quality and quality of finished products

4. The high temperature in the heating room causes excessive ablation of the furnace wall, which affects the service life of the furnace

5. There are many corners and dead corners in the rectangular furnace, and the temperature balance of the melt is poor, which is easy to form nodules and stones, which affects the normal operation of the furnace and the quality of the product.

6. Due to the high temperature and large quantity of exhaust gas from the furnace, in order to reduce energy consumption and improve the utilization rate of waste heat, it is necessary to attach a large and complex regenerator and waste heat utilization system
