Problems solved by technology

Because the kiln body is in motion during the production process of this kind of kiln, there is a relatively large limit on the weight of the kiln body. After installing necessary equipment on the kiln body, such as heat insulation and smoke exhaust, there is no more replacement Large space, the sulfur dioxide gas in the production process can not be installed with the current sulfur removal and dust removal equipment for good treatment, all of which are directly discharged into the atmosphere

Abstract

The invention discloses an environment-friendly rotary kiln which comprises an annular track (4) and a kiln body (21) which can move on the track (4); the environment-friendly rotary kiln is characterized in that a desulfurizer, a sewage pool (11) and a pulping pool (14) are arranged on the kiln body (21); the desulfurizer comprises a desulfuration room (20); and the desulfuration room (20) is a U-shaped or S-shaped pipeline body. Compared with the prior art, the environment-friendly rotary kiln is practical and is beneficial for reducing the discharge of sulfur dioxide effectively.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to an environment-friendly rotary kiln. Background technique [0002] In the production process of materials such as roasted bricks, tiles and ceramics, a large amount of sulfur dioxide gas will be produced, and the emitted sulfur dioxide gas will not only affect the health of operators, but also affect the surrounding ecological environment, and cause serious pollution to the air. Taking the brick with a section of 9388mm as an example: the standard coal consumption of the standard brick is 0.28kg / block, and the sulfur dioxide produced is 8mg / block. According to the daily output of 300,000 pieces, 2.4 million mg will be produced every 24 hours. [0003] At present, in the production process of roasted bricks, tiles and ceramics, especially in the roasting process, wheel kiln technology and tunnel kiln technology are mainly used at present. The kiln body is fixed on the ground, and the existing sulf...
