Exhaust passage for refractory material kiln

Abstract

The invention discloses an exhaust passage for a refractory material kiln, belonging to the field of refractory material production equipment and solving the problem that the waste heat recovery rate is low in the process of producing a refractory material. The exhaust passage for the refractory material kiln is communicated with an inner cavity of the high temperature kiln; the exhaust passage comprises a plurality of waste heat recovery pipes which penetrate through the side wall of the exhaust passage; a local part, positioned in the exhaust passage, of each waste heat recovery pipe is a waste heat recovery part; a non-obtuse-angle included angle between the axial direction of each waste heat recovery part and the axial direction of the exhaust passage is more than or equal to 80 degrees; the axial directions of all the waste heat recovery parts are parallel to one another; a distance between every two waste heat recovery parts is 5 to 10 times of the outer pipe diameter of each waste heat recovery part; the waste heat recovery pipes are hermetically communicated with the side wall of the exhaust passage; each waste heat recovery pipe is filled with a fluid refrigerant. The exhaust passage disclosed by the invention can be used for further recovering waste heat generated in the process of producing the refractory material, so that energy resources are saved and the economic benefit is increased.

Description

technical field [0001] The invention relates to the field of refractory material production equipment, in particular to an exhaust channel of a refractory material kiln. Background technique [0002] The production of refractory materials requires a high-temperature kiln. In order to increase the temperature of the kiln cavity, a large amount of fuel, such as coal, is burned, which will release a large amount of high-temperature gas. At the same time, when the high-temperature kiln for the production of refractory materials is also required Release the high-temperature gas in the chamber, generally the gas is discharged through the exhaust channel, and a lot of heat energy is wasted in this process. Contents of the invention [0003] The object to be achieved by the present invention is to provide an exhaust channel of a refractory kiln capable of recovering waste heat generated during the production of refractory materials. [0004] In order to achieve the above purpose,...
