Abstract

The utility model relates to a gas solid particle separation device, in particular to a cyclone separator. The cyclone separator comprises a separation cylinder (5), wherein the upper end of the separation cylinder (5) is provided with an upper cover (3), and the lower end of the separation cylinder (5) is connected with a cone (6); an exhaust pipe (2) is concentrically arranged on the upper cover (3); an air inlet (4) is arranged in the sidewall of the separation cylinder (5) along a tangential direction; walls of the exhaust pipe (2), the upper cover (3), the separation cylinder (5) and the cone (6) are membrane type water-cooled walls; and an inclined angle of 95 degrees to 100 degrees exists between the upper cover (3) and the separation cylinder (5). By adopting the membrane type water-cooled walls, the mixed gas is separated and cooled simultaneously, the temperature of the separated fuel coal particle is reduced, a secondary combustion phenomenon is stopped, and the smoke discharge temperature is reduced simultaneously; the inclined angle of 95 degrees to 100 degrees exists between the upper cover and the separation cylinder, thus bubbles are prevented from generating on corners of the upper cover and the separation cylinder effectively.

Description

A kind of cyclone separator

Technical field

The utility model relates to a kind of gas-solid particle separation apparatus, relates in particular to a kind of cyclone separator.

Background technology

Cyclone separator commonly used; Especially the divided gas flow used of boiler and the cold cyclone separator of vapour of coal-fired particle because the intake air temperature of cyclone separator is very high, cause the second-time burning phenomenon often occurring after the coal-fired particle separation; Thereby the after-burning coking occurs, exhaust gas temperature is very high simultaneously; Because the unreasonable structure that conventional cyclone separator is inner usually produces bubble around the corner, thereby cause the separating property of cyclone separator to reduce.

The utility model content

The utility model provides a kind of and has not been prone to the after-burning coking, and the turning is difficult for producing the cold cyclone separator of vapour of bubble.In order to realize the foregoing invention purpose, the utility model has adopted following technological means:

A kind of cyclone separator comprises the separation cylinder; The upper end of said separation cylinder is provided with loam cake, and the lower end connects the awl tube; Cover the concentric blast pipe that is provided with on said; Tangentially be provided with air inlet on the said separation cylinder side wall; The wall of said blast pipe, loam cake, separation cylinder and awl tube all is a fin panel casing; Said loam cake is 95 °-100 ° with the angle that separates between the cylinder.

The top of said blast pipe connects upper collecting chamber; The lower end of said awl tube connects the next part case.

The beneficial effect of the utility model is: adopt fin panel casing, in the time of separation mist is cooled off, reduced the temperature of isolated coal-fired particle, stopped the second-time burning phenomenon, also reduced exhaust gas temperature simultaneously; Loam cake and the angle that separates between the cylinder are 95 °-100 °, and such structure has effectively prevented to produce bubble at loam cake with the corner that separates cylinder.

Fig. 2 is the A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of cyclone separator of the utility model is made detailed description:

As depicted in figs. 1 and 2, this cyclone separator mainly comprises columniform separation cylinder 5, and its outer wall is provided with air inlet 4, air inlet 4 along the tangential direction of separating cylinder 5 in the shape of a spiral shape feed and separate in the cylinder 5.

The top of separating cylinder 5 is provided with the loam cake 3 of taper, loam cake 3 with separate angle between the cylinder 5 between 95 ° ~ 100 °, present embodiment adopts 100 °.The center of loam cake 3 is communicated with columniform blast pipe 2, and the corner between blast pipe 2 and the loam cake 3 is smooth.The top of blast pipe 2 connects upper collecting chamber 1.

The bottom of separating cylinder 5 is connected with awl tube 6, and the bottom of awl tube 6 connects next part case 7.

Blast pipe 2, loam cake 3, separation cylinder 5 and awl tube 6 all adopt fin panel casing to surround to make and form.

Separate on the inwall of cylinder 5, along the circumferential direction be set with radiating fin 8, also be provided with radiating fin 8 on the inwall of air inlet 4.

During the work of this cyclone separator, the high-temperature gas mixture body tangentially gets into from air inlet 4 and separates the cylinder 5, thereby forms the air-flow of rotation; Under action of centrifugal force, coal-fired particle is separated, and falls from awl tube 6; Flue gas is discharged from blast pipe 2, and in separation process, the fin panel casing that separates cylinder 5 cools off mist; Reduced the temperature of separating the after-burning coal particle, made it be difficult for second-time burning; Radiating fin 8 has strengthened the heating surface area of mist, makes the gas cooling faster; Loam cake 3 with separate angle between the cylinder 5 greater than 90 °, thereby prevented that the two corner from producing bubble.

Claims
