Embodiment 1

[0047] Such as figure 1 As shown, the most widely used conventional cement production system is mainly composed of cyclone preheater 1, decomposition reactor 2, rotary kiln 3, cooler 4, and tertiary air duct 7. The cyclone preheater 1 is generally composed of 4-6 cyclone separators or cyclone separator groups arranged in random order.

[0048] The decomposition reactor 2 is connected in series between the cyclone preheater 1 and the rotary kiln 3 , the rotary kiln 3 is located between the decomposition reactor 2 and the cooler 4 , and the decomposition reactor 2 and the cooler 4 are also connected through a tertiary air pipe 7 .

[0049] Cement raw meal enters from the top of the cyclone preheater 1, in the cyclone separator, the cement raw meal is separated from the gas, and then enters the lower stage cyclone separator from the bottom of the cyclone separator through the pipeline, and the second last stage from the bottom The bottom of the cyclone separator enters the decom...

Abstract

The invention discloses a cement raw material decomposition system using alternative fuel. The cement raw material decomposition system comprises a cement raw material decomposition reactor and a rotary drum type reactor mounted on the cement raw material decomposition reactor, the rotary drum type reactor is respectively communicated with a decomposition reactor on the cement raw material decomposition reactor and a tertiary air pipe; the rotary drum type reactor comprises a rotating mechanism rotationally connected with the decomposition reactor, a supporting mechanism is fixedly installed on the tertiary air pipe and is in contact connection with the rotating mechanism, the supporting mechanism is fixedly connected with a transmission mechanism, the transmission mechanism is in transmission connection with the rotating mechanism, and the rotating mechanism is rotationally connected with a feeding mechanism. And the feeding mechanism is fixedly connected with the tertiary air pipe. According to the method, under the conditions that the sources of the alternative fuel and the waste are unstable and the homogenization effect cannot be effectively guaranteed in the pretreatment process, the waste can be reliably, safely and conveniently treated and the alternative fuel can be effectively used under the condition that the production is not influenced.

Description

technical field [0001] The invention relates to the technical field of cement raw meal decomposition, in particular to a cement raw meal decomposition system using alternative fuels. Background technique [0002] The range of alternative fuels is very wide, including all kinds of domestic waste (including waste plastics, waste rubber, waste paper, waste tires, etc.), hazardous waste, urban and industrial sewage treatment sludge, animal and plant processing waste, polluted soil, Solid and liquid waste such as emergency waste. Moreover, with the continuous development of the economy, the amount of domestic garbage, municipal sludge, organic waste liquid, industrial hazardous waste and other wastes is increasing year by year. [0003] The cement pre-decomposition production system includes a cement cyclone preheater, a decomposition reactor, a rotary kiln, and a tertiary air delivery system for a cooler. It is the most widely used technical solution for modern cement productio...
