Abstract

The utility model provides another desulfurization-denitriding cyclone separator, which can shorten the length of a main air inlet pipeline, lessen airflow resistance, minish floor area, reduce the number of ash bins and cost down. The desulfurization-denitriding cyclone separator comprises an air inlet pipeline, three barrel bodies, an ash discharge bucket and an exhaust pipeline, wherein the exhaust pipeline comprises three branch pipes; output ends of the three branch pipes are converged to a total exhaust pipe; and input ends of the three branch pipes extend into the three barrel bodies respectively. The desulfurization-denitriding cyclone separator is characterized in that: the three barrel bodies are arranged in a triangular mode; connecting branch pipes are arranged among the air inlet pipeline and the three barrel bodies respectively along the direction of common tangents and are communicated with the air inlet pipeline and the three barrel bodies respectively; and the ash discharge bucket is arranged below ash discharge ports of the three barrel bodies.

Description

The desulfurization removing nitric cyclone separator

Technical field

The utility model relates to purifying in the petrochemical industry industry uses separator, is specially the desulfurization removing nitric cyclone separator.

Background technology

Cyclone separator is widely used in the cleaning equipment of petrochemical industry industrial circle, and the desulfurization removing nitric cyclone separator is wherein a kind of dry type gas-solid separating device.The desulfurization removing nitric cyclone separator that adopts at present comprises a main admission line, three cyclone separator bodies; The air communication that contains gas-solid two phase materials is crossed main admission line; Be diverted to the air inlet mouth of pipe of three cyclone separators again, air-flow tangentially gets into the cyclone separator cylindrical shell, forms the downward outer eddy flow of rotation; The dust that is suspended in outer eddy flow drops under the effect of centrifugal force, gravity and shifts to wall; And with circulate cyclone separator device bottom of outward turning, discharge by ash discharging hole, purified gas forms the interior eddy flow that rises and discharges through blast pipe.But the defective that this structure exists is: main admission line is oversize, causes gas-flow resistance to strengthen, and three cyclone separators are arranged side by side, and floor space is big; Three cyclone separator bottoms side by side are provided with three ash discharging holes, therefore need to be equipped with three grey storehouses, have increased the acquisition cost of equipment.

Summary of the invention

Have above-mentioned defective to prior art, the utility model provides another kind of desulfurization removing nitric cyclone separator, can shorten main admission line length, reduces gas-flow resistance, reduces floor space, reduces the quantity in grey storehouse, reduces cost.

Its technical scheme is such:

It comprises admission line, three cylindrical shells, ash bucket, discharge duct; Said discharge duct comprises three arms; The output of said three arms is aggregated into total air escape pipe; The input of said three arms stretches into respectively in said three cylindrical shells, it is characterized in that: said three cylindrical shells are triangularly arranged, and are provided with connecting branch in the common tangent direction respectively between said admission line and said three cylindrical shells; Described connecting branch is connected with said admission line, said three cylindrical shells respectively and communicates, and described ash bucket is arranged at the below of said three cylindrical shell ash discharging holes.

It is further characterized in that: said admission line is a bending tube; Said three cylindrical shells are equilateral triangle and arrange.

After the utility model adopts said structure; Three cylindrical shells are triangularly arranged, and are provided with connecting branch in the common tangent direction respectively between said admission line and said three cylindrical shells, and admission line can be simultaneously to three cylindrical shell air feed like this; Admission line shortens; A little less than the gas-flow resistance, three cyclone separators surround the triangle compact Layout, and floor space is little; Three ash discharging hole belows are provided with concentrated ash bucket, only need to be equipped with a grey storehouse and can collect dust, thereby can reduce cost; And said admission line is a bending tube; Said three cylindrical shells are equilateral triangle and arrange that the further like this compact structure that guaranteed guarantees that an ash bucket just can solve the problem of ash discharge, has further guaranteed lower acquisition cost.

Fig. 3 is the novel vertical view of this usefulness.

The specific embodiment

See Fig. 2, Fig. 3; The utility model comprises admission line 1, three cylindrical shells 2, ash bucket 4, discharge duct, and discharge duct comprises three arms, and the output of three arms is aggregated into total air escape pipe 3; The input of three arms stretches into respectively in three cylindrical shells 2; Three cylindrical shells 2 are equilateral triangle and arrange that admission line 1 is a bending tube, is provided with connecting branch in the common tangent direction respectively between admission line 1 and three cylindrical shells 2; Connecting branch is connected with admission line 1, three cylindrical shells 2 respectively and communicates, and ash bucket 4 is arranged at the below of three cylindrical shell 2 ash discharging holes.

Operation principle below in conjunction with accompanying drawing simple declaration the utility model; Gas-solid two phase air-flows get into admission line 1; Tangentially evenly be diverted to the air inlet of three cylindrical shells 2 again through admission line 1 bend pipe mouth, the resistance that the centrifugal force that produces in the cylindrical shell 2 makes gas-solid two phase materials overcome air-flow moves to wall, after material grains arrives near the wall; Because less turbulent flow in the boundary layer; Cause material grains to fall into the bottom ash discharging hole, collect dust through the concentrated ash bucket 4 of ash discharging hole bottom again, then get into three arms through three arm inputs on three cylindrical shell 2 tops through the isolated sulfur dioxide of cyclone separator, nitrogen along wall; Output through three arms converges to 3 discharges of total air escape pipe road again, can realize the purpose of desulfurization removing nitric.
