Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with specific embodiment,
The present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this reality
With novel, without constituting limitations of the present invention.
Embodiment 1
As shown in Figs. 1-3, a kind of moisture film plate filtering device, the filtering device are at least made of one group of barrier module 1, every group
Barrier module 1 is at least made of two or more moisture film board group parts, and moisture film board group part can be S-shaped, Z-shaped, W-shaped, in this implementation
In example, moisture film board group part is the Z-shaped component 3 of inclined rest, and Z-type component 3 is by upper flange, lower wing plate and is arranged between
Riser composition, tongue 5 is formed after 3 inclined rest of Z-type component between upper flange and riser, is formed between riser and lower wing plate recessed
Slot 6,3 one end of Z-shaped component are fixed in vertically arranged water inlet control module 2, and the other end is fixed on vertically arranged draining control
On molding block 9, the length of every Z-shaped component 3 is set as needed, and 6 two side of groove of every Z-shaped component 3 or bottom are at least set
There are row's regulator hole 4, the upper flange of inclined Z-shaped component 3 to be superimposed vacantly on the lower wing plate of another Z-shaped component, barrier mould
The groove 6 of each Z-shaped component 3 in block 1 remains that the moisture film of a laminar flow, barrier module 1 and the gas filtered out are installed,
Two groups or more of barrier module 1 is combined connection by the upper connector 8 that section is V-arrangement or lower connector 7, V-arrangement connector
Length and the length of Z-shaped component 3 are consistent.
Barrier module 1 is by the feed pipe and aqua storage tank in 2 outside of water inlet control module（Or the nozzle spray on Z-shaped component top
Leaching）Water source is provided, the sawtooth for 2 upper edge of control module that intakes is passed through（Or the nozzle on Z-shaped component top）Equably moisture is matched
At the groove 6 of more Z-shaped components 3, the liquid level at 3 groove 6 of Z-shaped component is different by the upper edge of draining control module 9
The height of shape sunk part controls, when the liquid level of Z-shaped component 3 is higher than the upper edge abnormity sunk part for draining control module 9
When height, water will be overflowed to by draining control module 9 in the drain tank in 9 outside of draining control module, and be drained by tapping pipe,
Barrier module 1 is set to remain the moisture film of a laminar flow through the above process.
Barrier module 1 is typically mounted at the demister lower part or exit of wet flue gas desulfurization tower, the Z in barrier module 1
Shape component 3 can also reduce the windage and the phenomenon of leakage of Z-shaped component, and by disconnected other than keeping water membrane by regulator hole 4
Face is the direction that Z-shaped structure guides air-flow, you can extends the gas-liquid mass transfer time, can also reduce air resistance coefficient, Z-shaped component tongue
5 leak out a little is closed by the upper edge abnormity projection portion of draining control module 9.
In order to reduce in air the nuclei of condensation of " haze ", need thin to the aerosol that is retained in wet process of FGD flue gas etc.
The pollutant of small particle is filtered out, when flue gas to be filtered out passes perpendicularly through moisture film plate filtering device with certain flow rate from bottom to top
When, flue gas can also form the emulsion layer being made of water mist, flue gas other than carrying out sufficient water-bath with the moisture film on Z-shaped component 3
In the pollutants such as the aerosol secondary dissolving and trapping of the emulsion layer that are made up of continuous phase water and water mist after, finally make wet method
Pure flue gas after flue gas desulfurization is discharged into air.
The key of moisture film plate filtering device is Z-shaped component, when on Z-shaped component liquid level and water leakage it is certain under conditions of,
Gas different in flow rate, which is simulated, by air blower passes through Z-shaped component, test data such as following table：
It is obtained from experiment and actual measurement data：Moisture film plate filtering device be directed to different gas different in flow rate, Z-shaped group
The windage that part+water film thickness generates only changes in the range of 45~190 Pa, and forms the water mist emulsification of 30~150mm thickness
Layer.By testing explanation：Moisture film plate filtering device has the characteristics that resistance is smaller, gas-liquid mass transfer effect is high.Moisture film plate filters out dress
The utility model set solves the problems, such as to be easy leak when gas flow rate present in sieve tray and inclined hole plate technique is low, and solves
Bubble cap tray gas by when resistance big problem.
The above specific implementation mode describes the basic principles and main features of the utility model.The technical staff of the industry
It is any to expect without creative work it should be appreciated that the scope of protection of the utility model is not restricted to the described embodiments
Variation is replaced, and should all be covered and is within the protection scope of the utility model.Therefore, the scope of protection of the utility model is answered
This is determined by the scope of protection defined in the claims.
