Abstract

The invention discloses a regenerative high-temperature air combustion energy-saving environment-friendly shuttle-type kiln, which is an efficient, energy-saving and combustion heating system comprising a kiln body, regenerative chambers or regenerative combustors and an air and flue gas reversing valve. The regenerative high-temperature air combustion energy-saving environment-friendly shuttle-type kiln adopts the novel regenerative HTAC (high-temperature air combustion) technology, enables the two regenerative chambers to be alternatively operated in the regeneration and heat release states by means of switching of the reversing valve to efficiently recover waste heat of flue gas, and leads combustion-supporting air to be preheated to be higher than 1,000 DEG C, so that fuel can be sufficiently combusted in the high-temperature oxygen-poor environment, the problem of fuel adaptability is effectively solved, the space of the whole hearth is filled with unique flames with no local high-temperature area, heat transfer in the kiln is more intense and uniform, output and heating quality of products are effectively improved, generation and total discharge amount of NOx (nitrogen oxides) and dioxin are restrained, and combustion noise is greatly reduced. The shuttle-type kiln has the advantages of high efficiency, energy saving, environmental protection, remarkable economic and social benefits and the like.

Description

Technical field [0001] The invention relates to a regenerative high-temperature air combustion energy-saving and environment-friendly shuttle kiln, which belongs to energy-saving and environment-friendly technical equipment in the field of industrial kilns. Background technique [0002] Shuttle kilns (also known as reciprocating kilns, drawer kilns or trolley kilns) evolved from traditional inverted flame kilns. Shuttle kilns are batch or semi-continuous kilns. The structure of the shuttle kiln is very similar to that of the matchbox. The working process is: a trolley (also called a kiln car) loaded with items to be heated or burned is pushed into the kiln, and the fuel is burned to complete the heating or burning process, and then Pull out the trolley in the opposite direction to get a heated or burned product. Because the trolley moves like a shuttle, it is called a shuttle kiln. [0003] Shuttle kiln has the advantages of small floor space, relatively small one-time fixed inve...
