Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 and 2 As shown, the double O-type lime kiln mainly consists of system components such as raw material conveying and mixing distribution system, kiln main structure, discharge system, dust removal system, and power equipment configured with each system. The main structure 1 of the kiln is double O-shaped; the wall of the main structure of the kiln is a fully sealed calcined structure, which consists of high alumina brick layer 11, light insulation brick layer 12, heat insulation fiber layer 13 and steel furnace shell from inside to outside. 14 compositions. The dust removal system is a bag dust removal system that mixes flue gas, dust and post dust at the same time for dust removal; the bag dust removal system includes a dust collector and several air induction hoods connected to the dust collector; the air induction hood includes electronic sc...

Abstract

The invention discloses a double-O-shaped lime kiln which comprises a raw material delivering mixing distributing system, a kiln main body structure, a discharging system, a dust removing system and a power device. The power device is configured with each system; the kiln main body structure is double-O-shaped; and the wall of the kiln main body structure is a fully sealed calcination structure and sequentially composed of a high-alumina brick layer, a light-weight insulating brick layer, a heat insulation fiber layer and a steel furnace shell from inside to outside. The double-O-shaped lime kiln has the advantages of being obvious in energy saving, high in automation degrees, high in qualities of finished products, low in construction costs, short in construction periods and capable of reaching the standard of environmental protection; the use ratio of fuel thermal values can reach over 80%, electric energy can be averagely saved by over 40%, and a microcomputer network control system is used so that production and activity are improved, labor intensity of workers is reduced, and working environment is improved; and according to the trail use, the double-O-shaped lime kiln is stable, reliable, low in fault rate, high in capability of interference resistance, high in accuracy of a weighing system, complete in functions and simple in operating.

Description

technical field [0001] The invention relates to a lime kiln, in particular to a double O type lime kiln. Background technique [0002] At present, calcined quicklime has a long history in our country. Up to now, the amount of ash used in metallurgy, chemical industry, and building materials industries is increasing, and the requirements for the quality of lime are also getting higher and higher. However, there are still a large number of low-cost common shaft kilns currently used for quicklime production in my country. There are many shortcomings in the production of ordinary shaft kilns, such as the low utilization factor of the kiln, which is below 50%; Due to the open structure, it is difficult to remove dust, and the environment is seriously polluted; feeding and ash are almost entirely manually operated, and the labor intensity is high, which seriously damages the health of the operator; More than 30%, and cannot be controlled in time.
