Embodiment Construction

[0022] Below with reference to the accompanying drawings, through the description of the embodiments, the specific embodiments of the present invention, such as the shape, structure, mutual position and connection relationship between the various parts, the role and working principle of the various parts, etc., will be further described. Detailed instructions:

[0023] as attached figure 1 As shown, the present invention is a chlorine removal device for co-processing solid waste in a cement kiln. The wind part 2 communicates, and the lower part of the high-temperature cyclone separator 1 communicates with the decomposition furnace 3 . In the above structure, the high temperature cyclone separator 1 is communicated with the high temperature cyclone separator 1 by connecting the wind-taking component arranged on the decomposition furnace, and then the high temperature cyclone separator 1 is communicated with the decomposition furnace 3 . In this way, when the cement kiln syste...

Abstract

The invention provides a dechlorination device co-processing solid waste with a cement kiln, and belongs to the technical field of cement kilns. The dechlorination device co-processing solid waste with the cement kiln comprises a high-temperature cyclone separator (1) and an air taking part (2), the air taking part (2) is installed on a decomposing furnace (3), the upper portion of the high-temperature cyclone separator (1) communicates with the air taking part (2), and the lower portion of the high-temperature cyclone separator (1) communicates with the decomposing furnace (3). The dechlorination device co-processing solid waste with the cement kiln is simple in structure and capable of effectively improving the dechlorination effect, harmful matter is discharged as much as possible, thekiln dust taking-out amount is decreased, accordingly, stable production of the cement kiln is facilitated, the solid waste processing quality and processing quantity are improved, and the economic benefit is increased for an enterprise.

Description

technical field [0001] The invention belongs to the technical field of cement kilns, and more specifically relates to a chlorine removal device for co-processing solid waste in cement kilns. Background technique [0002] The "Environmental Protection Technical Specifications for Co-processing of Solid Waste in Cement Kilns" (HJ662-2013) requires that the content of chlorine in the materials entering the kiln should not exceed 0.04%. In order to prevent the excessive accumulation of volatile elements and substances in the kiln during the internal circulation process, the co-processing enterprise can regularly perform bypass ventilation. Therefore, in the production process, in order to ensure the normal operation of the clinker firing system, a chlorine removal system is installed at the tail smoke chamber of the cement kiln. The dioxins produced during the combustion of solid waste (solid waste) will be completely decomposed in the decomposition furnace at a temperature of ...
