tempered glass furnace

Abstract

The invention aims to provide a glass tempering furnace with a high energy utilization rate and a long service life. The glass tempering furnace provided by the invention comprises a furnace body, wherein a plurality of high-temperature resistant infrared radiation plates are detachably mounted on the inner wall of the furnace chamber of the furnace body; infrared radiation layers are mounted on the surfaces, facing the interior of the furnace chamber, of the high-temperature resistant infrared radiation plates; thermal insulating layers are arranged on the surfaces, facing the wall of the furnace chamber, of the high-temperature resistant infrared radiation plates; the infrared radiation layers are made of dichroite slabs; the thermal insulating layers are ceramic fiber blankets. As the high-temperature resistant infrared radiation plates with the thermal insulating layers are mounted on the inner wall of the furnace, absorbent energy can be homogeneous radiated to a product to be sintered; the thermal insulating layers are arranged on the back surfaces of the infrared radiation plates so as to prevent heat from being transmitted to the wall of the furnace and ensure that energy is transmitted to the product to be sintered as much as possible through radiation; the high-temperature resistant infrared radiation plates prolong the service life of the furnace, improve the economic benefit, can reduce the requirement on quality grade of fire-resisting material on the wall of the furnace and lower the construction cost of the furnace.

Description

technical field [0001] The invention relates to a tempered glass furnace. Background technique [0002] my country's industrial kilns and industrial boilers are the main body of energy consumption, and industrial kilns generally have low thermal efficiency and relatively large energy waste. In view of the low effective utilization rate of energy and relatively large energy waste in industrial kilns, the main energy-saving measures generally adopted at home and abroad are: (1) use light-weight thermal insulation materials with good thermal insulation effects as much as possible; (2) Adopt far-infrared energy-saving paint spraying technology; (3) waste heat recovery and utilization of flue gas; (4) energy-saving technology of black body radiation elements. [0003] The traditional way is to use light materials with small heat capacity and insulation materials to build furnaces to reduce heat storage and heat dissipation losses. This energy-saving method only "blocks" the hea...

Problems solved by technology

[0006] The fundamental weakness of far-infrared coating technology is that the coating is easy to age. During actual use, it will continue to pulverize and fall off or be eroded by airflow. The thermal infrared emissivity will gradually decay, lose the infrared radiation function, and the thermal efficiency will decrease with time.
