Energy-saving device capable of preheating coal gas on ceramic kiln

Abstract

The invention discloses an energy-saving device capable of preheating coal gas on a ceramic kiln. The ceramic kiln sequentially comprises a single-layer or multilayer drying area and a single-layer preheating area. A cold coal gas pipe which extends transversely is arranged above the single-layer or multilayer drying area and the single-layer preheating area. A gas inlet manifold for cold coal gas is arranged above drying boxes at the head of the single-layer or multilayer drying area and is perpendicularly connected with the cold coal gas pipe. The lower part of the gas inlet manifold transversely enters the internal top of a drying box at the head of the single-layer drying area, or transverse branches of the gas inlet manifold enter internal tops of drying boxes at the head of each layer of the multilayer drying area. A plurality of coal gas preheating pipes are perpendicularly arranged at all sections of the gas inlet manifold in each initial drying box. A primary output pipe for preheated coal gas is arranged above drying boxes at the tail of the single-layer or multilayer drying area. A secondary output pipe for the preheated coal gas is arranged above a drying box at one position of the preheating area and is perpendicularly connected with an output manifold. The lower part of the secondary output pipe is connected with the preheating pipes which enter the preheating box at the position. By adopting the structure, a good energy-saving effect can be realized and the sintering quality of ceramic products can be effectively improved.

Description

technical field [0001] The invention relates to a ceramic kiln, in particular to an energy-saving device capable of preheating coal gas on the ceramic kiln. Background technique [0002] In the high-temperature firing zone of the ceramic kiln, the cold gas at 30°C is generally directly input for combustion and heating. Since the combustion of the cold gas is not sufficient, it will cause a large loss and waste of heat energy, which is not conducive to energy saving and consumption reduction. Moreover, cold The axial flow generated by the gas is relatively large, which will cause a certain temperature difference in each area of ​​the furnace, thereby affecting the firing quality of ceramic products, which needs to be improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an energy-saving device capable of preheating gas on a ceramic kiln, which can achieve a good energy-saving effect and effectively improve pro...
