High-temperature glaze firing process sintering gas tunnel kiln

Abstract

The invention discloses a high-temperature glaze firing process sintering gas tunnel kiln. The high-temperature glaze firing process sintering gas tunnel kiln comprises a chimney body. The chimney body comprises a first air inlet pipe, an outer shell, a heat conduction inner shell, a first water outlet valve, a first water outlet pipe, a first water inlet valve, a first water inlet pipe, a second connecting pipe, a second water inlet pipe, a second water inlet valve, a rotating nozzle, a smoke exhaust pipe, a dust falling pipe, a second air inlet pipe, a third connecting pipe, a first air outlet pipe, a bottom plate, fixing holes, a cover plate, a filter box, a circulating water pump, a second water outlet pipe, a U-shaped mounting plate, a plate-type filter screen, a third water inlet pipe, a third water outlet pipe, a second water outlet valve, a positioning column, a first magnet block, a second magnet block and a positioning hole. According to the high-temperature glaze firing process sintering gas tunnel kiln, the waste heat in the flue gas can be conveniently recycled, the energy-saving effect is achieved, the situation that a large amount of heat energy is wasted is avoided, dust in the flue gas can be removed, the situation that the dust in the flue gas pollutes the air environment is avoided, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of tunnel kilns, in particular to a gas tunnel kiln sintered by a high-temperature glaze firing process. Background technique [0002] Tunnel kiln is made of refractory materials, thermal insulation materials and building materials. It is a kiln similar to a tunnel with kiln cars and other vehicles inside. It is a modern thermal equipment for continuous firing. Tunnel kiln mainly includes the following Several types: kiln body, kiln conveying equipment, fuel combustion system, ventilation equipment, ventilation equipment: including smoke exhaust system, air curtain stirring system and cooling system. Its function is to make the air flow in the kiln flow in a certain direction. [0003] However, at present, the exhaust system of the existing high-temperature glaze firing process on the sintered gas tunnel kiln generally discharges the flue gas directly to the outside. The flue gas not only contains a large a...

Problems solved by technology

[0003] However, at present, the exhaust system of the existing high-temperature glaze firing process on the sintered gas tunnel kiln generally discharges the flue gas directly to the outside. The flue gas not only contains a large amount of heat energy, but also has certain dust, and the flue gas is directly discharged to the outside. Causes a lot of waste of heat energy, and the dust in the flue gas also pollutes the air environment; therefore, it does not meet the existing use requirements
