Abstract

The utility model relates to a vertical spiral waste gas cleaning device, which comprises a circular outer tower body, an exhaust gas inlet and an exhaust gas outlet. The utility model is characterized in that The interior of the circular outer tower body is provided with a circular inner core and a helical gas deflector in order to form a helical airflow channel with unambiguous interface, exhaust gas flow is compulsory to be rotated in the channel, and consequently, the harmful phenomenon of turbulent flow and turbulent flow is reduced to minimum. The utility model has the advantages of high cleaning efficiency, small ground occupation, ease processing and production and wide application scope. The utility model is mainly used for the separation of dust and droplet and the cleaning treatment of aeriform pollutant. Besides that the utility model can be used alone, the vertical spiral waste gas cleaning device can compose a combined cleaning device together with other cleaning mechanisms (such as a venturi pipe).

Description

Vertical spiral waste gas cleaning device

The utility model relates to the device that material is separated, and further is meant the purifier of dust, drop and the gas pollutant removed in the waste gas.

Cyclone separator is one of technical equipment commonly used in the exhaust-gas treatment, vertical cyclone separator commonly used at present, after waste gas enters the separator cylindrical shell from tangential direction, rotation voluntarily, utilize centrifugal force to separate dust or drop, but because the interface limit that there is no need in the air-flow rotation, eddy current, turbulent phenomenon are difficult to avoid, thereby the reduction purification efficiency, increase equipment resistance and energy consumption.Though wet method horizontal cyclone deduster has the function of forcing eddy flow, floor space is bigger, and has at waste gas and to be not easy under corrosive condition with nonmetallic materials (as granite) processing and fabricating.

The purpose of this utility model aims to provide a kind of purification efficiency height, floor space is little and is easy to the vertical helical waste gas purification apparatus of processing and fabricating again.

The solution of this vertical helical waste gas purification apparatus is achieved like this.It still comprises circular outer tower body, exhaust gas inlet and the waste gas outlet of existing cyclone separator, and feature part of the present utility model is, its circular outer tower body inside has circular inner core, circle outside, have in the space between the outer core in tower body inwall and the circle and circle outside the spiral guiding plate that is connected mutually of tower body and circular inner core.

Setting up of spiral guiding plate formed the clear and definite helical flow passage in interface, and waste gas stream is forced rotation in passage, thereby harmful eddy current and turbulent phenomenon are cut to bone.The rotating cycle of spiral guiding plate can be set as required.Compare with common vertical cyclone separator, it has higher purification efficiency; Compare with horizontal wet method cyclone separator, then floor space is little, and processing and fabricating is convenient, and accommodation is wider.This vertical helical waste gas purification apparatus is mainly used in the separation of dust, drop and the purified treatment of gaseous contaminant.Except that can using separately, also can form the purifier of combined type with its purification mechanism (as Venturi tube).

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the embodiment of a kind of concrete structure of the utility model;

Fig. 2 and Fig. 3 are respectively Fig. 1 vertical view of the present utility model and A-A cutaway view;

Fig. 4 is for setting up the embodiment of vertical Venturi tube before the vertical helical purifier;

Fig. 5 places the inner embodiment of double as inner core tube simultaneously of tower body for Venturi tube;

Fig. 6 is the embodiment of inner core tube double as purifying exhaust air fairlead.

Reference numeral among the above-mentioned figure is: 1, and circular outer tower body; 2, exhaust gas inlet; 3, waste gas outlet; 4, circular inner core; 5, spiral guiding plate; 6, gas channel; 7, nozzle; 8, jet pipe; 9, overfall; 10, downflow weir; 11, Venturi tube; 12, the purifying exhaust air fairlead.

Referring to Fig. 1, circular outer tower body (1), circular inner core (4) and spiral guiding plate (5) constitute the spiralling gas channel (6) of quadrangular section jointly.When waste gas rotated in spirality channel, dust and drop separated from the air-flow main body under centrifugal action, and the water-distributing device of the utility model device can adopt nozzle (7) or jet pipe (8), and the waste gas after the purification is discharged from waste gas outlet (3).The waste liquid that collection is stored in the tower bottom is then discharged by overfall (9) and downflow weir (10).

Referring to Fig. 4, before the vertical helical purifier, set up vertical (or horizontal) Venturi tube (11), then can further improve purification efficiency.

In Fig. 5 and Fig. 6, circular inner core (8) is also distinguished double as Venturi tube (11) and purifying exhaust air fairlead (12), simplifies the structure, and has improved the ratio of performance to price.

The utility model device is according to dielectric property, and available all kinds of common or anticorrosion, temperature-resistant materials are made.Its purification efficiency height, simple in structure, making is applied widely easily, can be widely used in the improvement of various waste gas in the environmental project.

Claims

1, a kind of vertical helical waste gas purification apparatus, comprise circular outer tower body (1), exhaust gas inlet (2) and waste gas outlet (3), it is characterized in that, its circular outer tower body (1) inside has circular inner core (4), have in the space between tower body circle outside (1) inwall and circular inner core (4) outer wall and circle outside the spiral guiding plate (5) that is connected mutually of tower body (1) and circular inner core (4).
