Ceramic particle preparation production line adopting tail gas secondary-combustion process

Abstract

The invention discloses a ceramic particle preparation production line adopting a tail gas secondary-combustion process, and belongs to the technical field of ceramic particle preparation processes. The ceramic particle preparation production line adopting the tail gas secondary-combustion process comprises a ceramic particle raw material mixing support equipment set, a ceramic particle raw material forming support equipment set, a ceramic particle sintering equipment set and a fuel supply line, wherein the ceramic particle raw material mixing support equipment set is composed of a raw material supply line and a stirring device; the ceramic particle raw material forming support equipment set used for receiving raw materials and preparing the raw materials into ceramic particle blanks; theceramic particle sintering equipment set used for sintering ceramic particles, the sintered ceramic particles are guided into a secondary combustion chamber first, a backflow branch delivers part of tail gas into the secondary combustion chamber to achieve secondary combustion, and the ceramic particles in the secondary combustion chamber are pre-cooled; and the fuel supply line is used for delivering fuel into a rotary kiln. The ceramic particle preparation production line is used for preparing the ceramic particles; part of tail gas flows back into the secondary combustion chamber to achievesecondary combustion, so that the content of organic pollutants in the tail gas is effectively reduced, the burden of a subsequent deodorization device is reduced, and the investment of relevant devices and the material cost are reduced.

Description

technical field [0001] The invention relates to the technical field of ceramsite preparation technology, in particular to a production line for ceramsite preparation using tail gas secondary combustion technology. Background technique [0002] Ceramsite, as the name suggests, is ceramic particles. Most of the appearance characteristics of ceramsite are round or elliptical spheres, but there are also some imitation gravel ceramsites that are not round or elliptical spheres, but irregular gravel, and its surface is a hard shell. The shell is made of pottery or enamel, which has the function of water-proof and air-retaining, and gives the ceramsite high strength. Lightness is the most important point among many excellent properties of ceramsite, and it is also the main reason why it can replace heavy sandstone to prepare light aggregate concrete and light mortar. [0003] Ceramsite is usually sintered from ceramsite raw materials in a rotary kiln. When ceramsite raw materials...

Problems solved by technology

[0003] Ceramsite is usually sintered from ceramsite raw materials in a rotary kiln. When ceramsite raw materials contain organic waste, incompletely burned organic gaseous substances are usually produced during the sintering process, such as the Chinese invention patent with application number 201710287802.9 Disclosed is a method for preparing ceramsite using polluted soil and industrial sludge and the prepared ceramsite, which will inevitably produce incompletely burned organic pollutants under roasting conditions, although deodorization equipment can be used to treat them organic pollutants, but it will inevitably increase equipment investment and material (such as ozone, etc.) costs. Now a new ceramsite sintering production line is urgently needed to solve this problem, and the sintering process of the production line needs to be improved.
