AI Technical Summary

Technical Problem

In the cement production process, dechlorination ash mixed into the clinker silo affects the cement quality. Existing technologies are unable to effectively control the flow of dechlorination ash, which hinders the production of high-strength cement.

Method used

Design a cement kiln dechlorination ash separation and control ash discharge device. By changing the conveying path of dechlorination ash through a three-way valve, and combining it with a steel silo, bucket elevator and filter bag dust collector, the dechlorination ash can be separated from cement and reused.

Benefits of technology

It effectively prevents dechlorination ash from mixing into high-strength cement, ensures cement quality, realizes environmentally friendly treatment and reuse of dechlorination ash, and improves the environmental friendliness and efficiency of cement production.

Abstract

The utility model discloses a cement kiln chlorine ash removal branch control ash discharge device which comprises a steel plate bin and a three-way valve, the steel plate bin is connected with an ash pipe, the ash pipe is communicated with a grate cooler, the grate cooler is communicated with a clinker silo, the three-way valve is connected with the ash pipe, the three-way valve is connected with a belt dust collection ash hopper, and the belt dust collection ash hopper is connected with a clinker silo. The belt dust collection hopper is connected with a filter bag dust collector; the flow direction of the dechlorination ash is changed through the three-way valve, when high-strength cement is produced, the dechlorination ash is fed into the belt dust collection hopper, gas and the dechlorination ash are separated, the dust raising problem of the dechlorination ash can be solved in cooperation with the filter bag dust collector, cement production is more environmentally friendly, the dechlorination ash is prevented from being mixed into the high-strength cement, and the quality of the high-strength cement is guaranteed; when ordinary cement is produced, the three-way valve guides the chlorine-ash-removed mixed cement, and recycling of chlorine ash is achieved.
