Abstract

The utility model belongs to a dust removing apparatus, which is suitable for the dust removing and the dust collection of the dusty gas. The dust removing apparatus is provided with an inlet connected to a cylinder body in a tangential direction, the top of the cylinder body is connected to an exhaust core pipe, the lower part of the cylinder body is connected to a cone whose bottom is connected to a discharge air lock, and the cylinder body is coiled to form a plurality of turns according to the shape of the Archimedes spiral. The dusty gas enters through the inlet and flows along a spiral shaped passage to cause the dust to be collected to separate from time to time, the dust is exhausted by the discharge air lock, and the waste gas is exhausted by the exhaust core pipe. The dust removing apparatus has advantages of high dust removing efficiency, low pressure loss, small volume, light weight and low cost.

Description

Helical type cyclone dust collectors

The utility model relates to a kind of dust arrester of dusty gas.

To the dedusting of dusty gas, the similar device of use and the utility model has now: cyclone dust collectors such as CLT/A, XLP/A, XLP/B, XLP/G, XCX, XP, CLK, PW, XS, XND/G, HX1410.These type cyclone dust collectors mainly all are to utilize the tangential flow field of air-flow to make the dust granules generation centrifugal intertia force and the separation that is captured.Though some difference of its concrete structure, its basic identical structure all are to become with outer cylinder to insert in the tangential dusty gas import that connects, the outer cylinder by one to connect a cone below an exhaust core pipe, the outer cylinder, cone base connects the discharge airlock and constitutes.These class cyclone dust collectors, because outer cylinder is simple cylinder, and exhaust core pipe inserts in the tube, so make dust granules be in the stack of source (class source) and remittance (class remittance) air velocity distribution, confluxing moves inward dust granules, is discharged by exhaust core pipe then, and dust catching is separated.Since exhaust core pipe insert in the cylindrical shell part and urceolus between form cylindrical shell time stream because this kind time stream effect, make to capture isolated dust granules and discharge by exhaust core pipe again.Also because this structure makes moving radially apart from bigger of dust granules, being difficult for is captured from air-flow separates.Above-mentioned these are to cause the existing not high reason of all kinds cyclone dust collectors efficiency of dust collection.Because the draw ratio of these type cyclone dust collectors is bigger, cone is longer, has caused the pressure loss bigger, and not long-pending bigger, weight is bigger, and cost is higher.

The purpose of this utility model is that a kind of improved cyclone dust collector will be provided.Reduce the contradiction of the source remittance stack in the air velocity distribution, reduce cylindrical shell time stream effect, improve efficiency of dust collection, reduce the pressure loss, reduce volume, the reduction cost.

The utility model purpose is achieved in that as depicted in figs. 1 and 2.The dusty gas import becomes tangential and connects with cylindrical shell, the cylindrical shell top connects with exhaust core pipe, and the cylindrical shell bottom connects with cone, and its underpart connects with discharge town wind apparatus.

The utility model cylindrical shell is for to be rolled into some circles by the Archimedes spiral shape, and exhaust core pipe does not insert inner barrel.

The utility model is because dust-contained airflow along helical type channel flow, has made full use of the tangential flow field of air-flow, and radial distance is short, helps dust granules and captures separation.Because exhaust core pipe does not insert inner barrel, reduce cylindrical shell time stream effect, thereby reduce to be captured and separate the escape of dust, efficiency of dust collection height.Because the ratio of height to diameter of deduster is little, cone is short, so the pressure loss is little, volume is little, and is in light weight, and cost is low.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is that Fig. 2 is its sectional view according to the appearance assumption diagram of the helical type cyclone dust collectors that the utility model proposes.

Describe details and working condition in detail below in conjunction with Fig. 1 and Fig. 2 according to the concrete device that the utility model proposes.

This device comprises a dusty gas inlet (1), the dusty gas inlet becomes with cylindrical shell (2) tangentially to connect, be rolled into some circles by the Archimedes spiral shape in the cylindrical shell, cylindrical shell top attachment one exhaust core pipe (3), the cylindrical shell bottom connects with cone (4), and the cone lower end connects with discharge airlock (5).

Claims

1. be used for the helical type cyclone dust collectors that dusty gas purifies, a gas access (1) that becomes tangential connection with cylindrical shell (2) is arranged, it is characterized in that cylindrical shell is rolled into some circles by the Archimedes spiral shape, the cylindrical shell top connects with exhaust core pipe (3), the cylindrical shell bottom connects with cone (4), and the cone bottom connects discharge lock ridge device (5).

2. device according to claim 1 is characterized in that exhaust core pipe does not insert inner barrel.
