Assembly type heat-pipe steam generator of kiln furnace

Abstract

The invention discloses an assembly type heat-pipe steam generator of a kiln furnace; a plurality of groups of heat-pipe heat-exchanging assemblies are installed in a smoke box; each group of heat-pipe heat-exchanging assemblies is formed by fixedly connecting a movable top plate of the smoke box as well as a plurality of heat pipes and sleeve assemblies which penetrate on the movable top plate; and each sleeve assembly is formed by connecting sleeves enclosed on the upper part of the heat pipes on the movable top plate; the upper parts of the sleeves are communicated with a steam dome through a connecting pipeline and a gas valve; and the lower parts of the sleeves are communicated with water outlets at the lower part of the steam dome through a connecting pipeline and a water valve. In comparison with the prior art, the assembly type heat-pipe steam generator disclosed by the invention is capable of solving the problems that the traditional heat-pipe steam generator is difficult to repair and replace and has poor adaptability to the fluctuant working conditions of the kiln furnace and high maintenance cost, and is beneficial to improvement of the reliability of the heat-pipe steam generator as well as standardization and normalization of design, production, installation, use, maintenance and other aspects of flue gas waste heat recovery for the kiln furnaces.

Description

technical field [0001] The invention relates to the technical field of manufacturing kiln flue gas waste heat recovery equipment, in particular to a waste heat recovery equipment that produces steam by conducting heat from flue gas in a kiln flue to heat water through heat pipes. Background technique [0002] Industrial kilns such as rotary kilns, pool kilns, steel rolling heating furnaces and other industrial equipment for smelting or heating, melting non-metal or metal are large energy consumers. According to statistics, the total energy consumption of industrial kilns in my country currently accounts for about 10% of the total energy consumption in the country. 1 / 4 of that, the average energy efficiency is 10-30% lower than the foreign advanced level, and the energy-saving potential is huge. The exhaust gas temperature of industrial kilns is generally 350-650°C, part of the heat can be recovered to preheat the combustion air, and most of the waste heat can be recovered to ...
