Novel cement kiln denitration and desulfurization catalytic system with double-disc paddle hourglass reversing function

Abstract

The invention discloses a novel cement kiln denitration and desulfurization catalytic system with a double-disc paddle hourglass reversing function. The system structurally comprises a branch pipe storage box, a lime storage tank, a bent pipeline, a double-disc long cylinder device, a cement powder cylinder, a rotary grinding tank and a chain belt engine. According to the invention, the double-disc long cylinder device is matched with the rotary grinding tank to form a separating-funnel-shaped rotary rack, wherein an upper inclined top tray, a lower inclined top tray and an air bellow groove bottom tray are provided with the separating funnel-shaped rotary rack for driving a shutter top frame block and a shutter bottom base block to perform groove separation feedback, so that the adhesiondegree of gas after denitration and desulfurization is removed by a rolling brush; after high-purity cement powder is output, the retained gas and impurity blocks can be reversed and fed back to the lime storage tank, so that the effect of cleaning by workers is achieved; humanized separate storage of the solid and gas by equipment is ensured; particle saturation precision of the material is improved; compactness and flatness of particles are simply and conveniently operated and treated; and easy pipeline processing operation of maintenance equipment is brought to a cement kiln, and quality ofcement powder is improved.

Description

technical field [0001] The invention is a novel double-disk propeller hourglass reversal catalytic system for denitrification and desulfurization of a cement kiln, which belongs to the field of cement processing equipment. Background technique [0002] Cement kiln is a kind of calcined material operation for preparing limestone into cement, extracting calcined particle powder, forming the crushing and mixing processing effect of bulk material, so that cement powder is homogeneously bagged and output, which affects the rotary analysis of parts in cement kiln The spacer pad consumes a lot, and the high-hardness collision work will severely wear the parts of the internal environment. The shortcomings of the current technology that need to be optimized are: [0003] In the cement kiln, the calcination of cement will be mixed with smoke and dust gas, and if it is not collected in the internal environment, it will cause the accumulation of large particles of sediment. When the cem...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a new type of denitrification and desulfurization catalytic system for cement kiln with double-disk oar hourglass reversal, so as to solve the problem that in the cement kiln, the calcination of cement will be mixed with smoke gas and dispersed in it. If the environment is not collected, it will cause the accumulation of large particles of sediment, so that when the cement powder is exported, the fine sand will be mixed with particles, which will affect the purity of the cement and the viscosity of the later use. And the high degree of particle hardness will bump the inner turntable and the knife holder, causing the blades to be pitted ahead of time and lose their flatness, and the consumption of internal parts is huge, and the collection and separation operations in the cement kiln are insufficient, allowing the mixed sulfur-containing and nitrate-containing gases to settle and adhere in a small amount On the surface of cement powder, the root cannot be removed
