Energy-saving type low-temperature-difference ultra-wide ultra-long tunnel sintering kiln

Abstract

The invention discloses an energy-saving type low-temperature-difference ultra-wide ultra-long tunnel sintering kiln which is provided with a kiln body and a control system; the kiln body is divided into a pre-heating section, a sintering section and a cooling section; a combustion-supporting air device is distributed on the kiln body; the combustion-supporting air device is equipped with an air inlet pipe, an air outlet pipe and a hot air pipe; the pre-heating section of the kiln body is equipped with a smoke exhaust device; a combustion system is arranged on the pre-heating section and the sintering section of the kiln body; the combustion system is equipped with a plurality of flame spray guns and a plurality of groups of temperature measuring sensors; the flame spray guns are arranged on the side wall of the pre-heating section of the kiln body and the side wall of the sintering section of the kiln body, are uniformly arranged along the longitudinal axis of the kiln body, and are arranged in delta type; and the temperature measuring sensors are uniformly arranged along the longitudinal axis of the pre-heating section of the kiln body and the longitudinal axis of the sintering section of the kiln body, and extend into the kiln body. The energy-saving type low-temperature-difference ultra-wide ultra-long tunnel sintering kiln is characterized in that net width of the inner section of the kiln body is 4.5-5.0m, and overall length of the kiln body is 300m. The tunnel sintering kiln disclosed by the invention is reasonable in layout, is stable in quality of sintered products, is energy-saving and environmentally-friendly, and is high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of ceramic firing kilns, in particular to an energy-saving firing kiln with an ultra-wide and ultra-long tunnel with low temperature difference. Background technique [0002] At present, the existing ceramic firing tunnel kiln generally adopts a tunnel firing kiln with a clear section width of 2.5m-3.5m and a kiln length of less than 80 meters. The burners in the existing firing kiln are equipped with several intermediate High-pressure flame spray gun and several groups of temperature measuring sensors: several flame spray guns are installed on one side of the side wall of the kiln body, and each group of several groups of temperature measuring sensors is composed of two temperature measuring sensors, each group The two temperature measuring sensors in the kiln body are respectively installed in the middle of the top of the inner wall of the same section of the kiln body and the middle part of the side wall ...
