Problems solved by technology

When RDF is input into the calciner of the cement kiln system for disposal, due to the low utilization rate of the feeding device and the low feeding rate, it is easy to cause RDF accumulation and blockage, reducing the disposal efficiency

Embodiment Construction

[0012] In order to better understand the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0013] Such as figure 1 As shown, a cement kiln co-processing RDF entering kiln system and process, refuse-derived fuel (RDF) is transported to the feeding hopper 2 of the RDF entering kiln system by a belt conveyor 1, the feeding hopper is vertically arranged, and the belt conveying device It is installed horizontally above the discharge hopper, the outlet at the bottom of the discharge hopper is connected to the feed port of the rotary discharge valve 3, the RDF enters the rotary discharge valve, and the shaftless reamer conveyor 4 is set on the rotary discharge valve. Below the material valve, the discharge port at the bottom of the rotary discharge valve is connected with the feed port of the shaftless reamer conveyor. The radius of the inlet and outlet of the feeding hopper, the rotary discharge...

Abstract

The invention provides a kiln accessing system and technology coprocessing RDF for a cement kiln. Opening diameters of a blanking hopper opening, a rotation discharge valve and a non-shaft reamer conveyor are enlarged by the kiln accessing system; horizontal height of the non-shaft reamer conveyor is blocked up; accumulation and blocking of the RDF are avoided; input quantity of the RDF is increased; wind pressure is improved by a Roots blower; the input speed of the RDF is increased. According to the invention, blocking during the discharging and kiln accessing of the RDF is reduced; operation rate and working efficiency of equipment are improved; producing operating cost is reduced; energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of cement kiln processing refuse-derived fuel (RDF), in particular to a kiln feeding system and process for co-processing RDF in a cement kiln. Background technique [0002] At present, industrial co-processing of waste technology has gradually become a new perspective in the treatment of domestic waste. It can not only eliminate the pollution of waste to the environment, but also provide raw materials and fuel for existing industries. Among them, the environmental friendliness and the economy of investment and operating costs of the cement industry's treatment of solid waste have been recognized by countries all over the world. Send the garbage directly to the cement plant, and build a pretreatment workshop in the cement plant to screen, remove iron, winnow, crush, remove non-combustible inorganic substances, squeeze out water, etc., and select the combustible part. The selected combustible parts are crush...
