Description

A kind of high-temperature corrosion resistance power demister

Technical field

The utility model relates to industry environmental protection fields, and in particular to a kind of high-temperature corrosion resistance power demister.

Background technique

It is most of first to need to carry out spray pretreatment by waste gas treatment process, then just enter waste gas treatment equipment and carries out Processing.Just contain a large amount of steam inside gas so after pretreatment, the waste gas treatment equipment of rear end is had very big It influences, existing physically demister has certain effect, but demisting efficiency is not it is obvious that about only 50-60%, therefore Whether can high efficiency remove exhaust gas in steam become exhaust-gas treatment industry key.And conventional power demister is due to electricity Machine be it is built-in, among the exhaust steam passage, therefore be not suitable for the exhaust gas under the environment such as processing high temperature, corrosion.

Summary of the invention

The utility model aim is to provide a kind of high-temperature corrosion resistance power demister, after efficient removal spray pretreatment Steam in exhaust gas, and promote the tolerance to adverse circumstances such as high temperature, corrosion.

In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of high-temperature corrosion resistance power demister, Including a shell, shell is divided by front with this successively every setting first partition and second partition from front to back in shell The motor separate cavities of air-inlet cavity, intermediate air-out chamber and rear portion；

The motor separate cavities three of the air-inlet cavity of the front, intermediate air-out chamber and rear portion seals off each other； The position that the air-inlet cavity of front is corresponded on the shell is equipped with air inlet, and the position of the air-out chamber among correspondence is equipped with outlet air Mouthful；At least one demister is equipped in the air-out chamber of the centre；

The demister includes a catchment covers, a demisting impeller, a tubular bracket and a motor；The catchment covers are by one Tubular cover circle and a back-supported face are constituted, and the front end of tubular cover circle is set up in the first partition as exhaust gas inlet, institute Back-supported face is stated to be made of the more supporting ribs being radially arranged along tubular cover circle of a center retainer plate and periphery, The inner end of each supporting rib is fixedly connected with center retainer plate, and outer end is fixedly connected with the rear port edge of tubular cover circle, with This forms exhaust steam passage hole between each adjacent supporting rib, also, the peripheral edge in each exhaust steam passage hole on towards tubular Rollover is equipped with the flange that catchments in cover circle；The tubular bracket is a cylindrical body, the back branch of front-end port and the catchment covers The fixed docking in support face, the motor separate cavities at its rear end towards the rear portion extend and are fixed on second partition, the cylinder of tubular bracket Waste gas outlet is laid on wall；The motor is located in the motor separate cavities at rear portion, and a transmission is stretched out on the output end of motor Axis, which protrudes into forward intermediate air-out chamber, and extends and connect with the center driving of the demisting impeller；

Under working condition, exhaust gas enters the air-inlet cavity of front through the air inlet, flows through exhaust gas inlet, the demisting of demister Impeller, exhaust steam passage hole, waste gas outlet to intermediate air-out chamber, are most constituted the road of exhaust gas circulation with this through air outlet pass-out afterwards Diameter.

In above scheme, multiple demisters are set side by side in the air-out chamber of the centre；Under working condition, described in exhaust gas warp Air inlet enters the air-inlet cavity of front, is divided into multichannel, and each road flows through the exhaust gas inlet of corresponding demister, demisting impeller, exhaust gas Access opening, waste gas outlet converge to intermediate air-out chamber, and the path of exhaust gas circulation is most constituted with this through air outlet pass-out afterwards.

In above scheme, the demisting impeller includes a center fixed body, periphery wheel rim and more blade strips, described Periphery wheel rim concentric ring is set to the periphery of center fixed body, and radially emitting shape is uniformly fixedly connected on the more blade strips Between center fixed body and periphery wheel rim；The blade strip is strip shape body.

Further, the cross section of the blade strip is rectangle.

Further, it is characterised in that: it is flat that the more blade strips are divided into parallel two in the axial direction of demisting impeller Face arrangement, so as to form front side blade face and rear side blade face, is connected with reinforcement between front side blade face and rear side blade face Muscle.

In above scheme, " air-inlet cavity, intermediate air-out chamber and the motor separate cavities at rear portion that shell is divided into front " In " front ", " centre ", " rear portion " be the direction that is flowed through according to exhaust gas to define, exhaust gas is flow in the past after.Therefore " front ", " centre ", " rear portion " be not it is unrelated with the actual orientation up and down of demister, specifically, front can be located at demisting fill The practical lower section set, rear portion are located at the practical top of demister；Can also be with, front be located at demister practical left side, after Portion is located at the practical right side of demister, can exchange.

Due to the application of above-mentioned technical proposal, the following bring effect of the working principle of the utility model is as follows:

1, air-inlet cavity, intermediate air-out chamber and the electricity at rear portion of front have been separated out in shell due to the utility model The motor of demister is placed in the motor separate cavities at rear portion by machine separate cavities, i.e., by motor and exhaust gas flow through path completely every It leaves, therefore can handle the exhaust gas of the adverse circumstances such as various high temperature, corrosion；

2, since the demister that the utility model uses is to be intercepted with the rotation of motor driven demisting impeller with demisting impeller Steam inside exhaust gas is gathered in collection along certain motion profile so that the steam inside exhaust gas is under the influence of centrifugal force The flange that catchments of water cover is formed in slot, and demisting efficiency can reach 95% or more；

3, the utility model has the advantages that installation speed is fast, and each demister is a set of stand-alone assembly, when installation Installation can be completed in the installation screw that catchment covers surrounding need to only be fixed；

4, the utility model has the advantages that debugging is simple, and debugging when only needs all to connect all motor power-supply wires To control cabinet, start control cabinet switch button, all demisters are just all run simultaneously；

5, the utility model has the advantages that sync rates are high, because all demisters are while running, and motor will not be by The influence of temperature environment, therefore the parameters such as the revolving speed of all demisters, frequency, windage are consistent；

6, the adaptable strong advantage of the utility model can adapt to the exhaust-gas treatment of various different air quantity, only need to increase Add the quantity of demister；

7, the utility model has the advantages that failure rate is low, since the motor of all demisters is kept apart with exhaust gas, no The probability that can be influenced, therefore broken down by environmental factors such as exhaust gas will substantially reduce；

8, the utility model has the advantages that easy to maintain, and when maintenance need to only extract entire demister out, is washed away with air gun It is clean；

9, the utility model has the advantages that stable, since all demisters are synchronized, frequency, together resistance together, Integral device operation is just quite stable.
