Description
Technical field
The utility model relates to cyclone separator field, particularly relates to a kind ofly air inlet pipe have been made to the cyclone separator improved.
Background technology
Cyclone separator is a kind of equipment of the separation for gas-solid system or liquid-solid system.Operation principle is tangentially introduce the rotary motion caused by air-flow, makes to have to get rid of compared with the solid particle of Great inertia centrifugal force or drop to separate to outside wall surface.It is the very wide a kind of separation equipment of industrial application.The major function of multicyclone apparatus removes the solid particle polluter and drop that carry in conveying gas as far as possible, reaches gas-solid-liquid and be separated, to ensure the normal operation of pipeline and equipment.
The separating effect of cyclone separator and the rate of flow of fluid of air inlet have very large association, and when gas enters separator interior from air inlet, flow velocity is larger, and in gas, the centrifugal force of solid particle or drop is larger, and separating effect is better.Prior art condition lower inlet duct and cylindrical shell junction are air inlet, and gas inlet speed is slow, and in gas, the centrifugal force of solid or liquid is little.
Utility model content
The utility model in order to overcome deficiency of the prior art, provides and a kind ofly air inlet pipe has been made to the cyclone separator improved.
The utility model is achieved through the following technical solutions:
A kind of cyclone separator with spiral air inlet, comprise air inlet pipe, escape pipe, cylinder cover, conical shell, described cylinder cover is connected with conical shell, upper sealing plate is provided with above cylinder cover, described escape pipe gos deep into cylinder cover inside through upper sealing plate, surge hopper is provided with below described conical shell, described surge hopper is by upper tapering, hypocone is formed jointly, upper tapering is connected with conical shell lower end, described air inlet pipe comprises helix tube, straight tube, helix tube is connected with straight tube, described helix tube is arranged along cylinder cover inwall, the cross section of described helix tube successively decreases gradually from straight tube junction, the swing angle of helix tube is 180 °.
The decline inclination angle of described helix tube is 5 ° ~ 15 °.
The cross section of described helix tube is rectangle.
The cone angle of described conical shell is 20 ° ~ 30 °.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by being arranged to helical form by the air inlet pipe of cyclone separator, and the cross section of air inlet pipe reduces gradually, and gas flow flow velocity after air inlet pipe improves, thus enhances separating effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of the utility model air inlet pipe.
In figure: 1, air inlet pipe; 1a, helix tube; 1c, air inlet; 1b, straight tube; 2, escape pipe; 3, cylinder cover; 4, surge hopper; 4a, upper tapering; 4b, hypocone; 5, conical shell; 6, upper sealing plate.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, described a kind of cyclone separator with spiral air inlet, comprise air inlet pipe 1, escape pipe 2, cylinder cover 3, conical shell 5, cylinder cover 3 is connected with conical shell 5, is provided with upper sealing plate 6 above cylinder cover 3; It is inner that described escape pipe 2 gos deep into cylinder cover 3 through upper sealing plate 6; Surge hopper 4 is provided with below conical shell 5, surge hopper 4 is made up of jointly upper tapering 4a, hypocone 4b, upper tapering 4a is connected with housing 5 lower end, the solid separated or liquid enter surge hopper 4 from conical shell 5, because the junction cross section of upper tapering 4a and hypocone 4b increases, make air velocity rapid drawdown in surge hopper 4, solid, liquid no longer by centrifugal action, thus drop on bottom surge hopper 4.
The cone angle of described conical shell 5 is 20 ° ~ 30 °.
As shown in Figure 2, described air inlet pipe 1 comprises helix tube 1a, straight tube 1b, and helix tube 1a is connected with straight tube 1b, and described helix tube 1a arranges along cylinder cover 3 inwall, and the cross section of helix tube 1a successively decreases gradually from straight tube 1b junction.
The decline inclination angle of described helix tube 1a is 5 ° ~ 15 °; The cross section of helix tube 1a is rectangle; The swing angle of helix tube 1a is 180 °.
Operation principle of the present utility model is: a part for air inlet pipe have employed the helix tube 1a of 180 °, backspin when ensure that gas enters separator interior; The cross section of helix tube 1a successively decreases gradually, and when air inlet, the flow velocity of gas is accelerated, until flow velocity reaches maximum when arriving air inlet 1c, thus increases the centrifugal force of solid or liquid in gas, enhances separating effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
