Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.
The invention provides a kind of wet cottrell, comprise cathode filament 6 and positive plate group 8, cathode filament 6 passes in the middle of positive plate group 8, it is characterized in that: positive plate group about 8 respectively has an electric power system, be connected with cathode line two ends respectively, cathode filament 6 has two sections, is connected by insulator 14, power supply has two, and every section of cathode filament 6 all connects one of them power supply.
The advantage of this structure is: two cathode filaments are independently power supply control, so voltage can be different, and like this can for the feature of flue gas, carry out the adjustment of voltage, in the import department of flue gas, dust is many, the voltage of the cathode filament 6 of this section can be tuned up, can better dedusting, from the import department of flue gas down, the relative import department of dust will lack, the voltage of the cathode filament of another section can be turned down, by such adjustment, dedusting effectively, and can reduce costs.
Two sections of cathode filaments are connected by insulator 14, and the position of insulator 14 can be put arbitrarily, and the length of insulator 14 also can regulate arbitrarily, according to the characteristic distributions of deduster dust, put suitable position, suitable length, more can improve the efficiency of dedusting.
Connected by insulator 14 just because of this two sections of cathode filaments, and the structure of two independently-powered controls of cathode filament, the wet cottrell of two one poles is being connected, after the wet cottrell series connection of two one poles, the cathode filament 6 of two one poles is connected by insulator 14, the cathode filament 6 of two one poles connects power supply respectively, and the cathode filament 6 of each one pole is powered independent control.Under these circumstances, by the wet scrubber of two one poles, an entirety can be made.When doing integrally, only have 1 cathode filament from top to bottom, efficiency of dust collection is not high.And structure of the present invention is done integrally, because two cathode filaments independently connect power supply, respectively by respective Energy control, efficiency of dust collection is unaffected, and due to two one pole wet cottrells as a whole, reduce the height of whole equipment, also save two-layer anode built-in beam simultaneously, two cover cathode wire fixing devices, have saved a set of spray system, have reduced the initial outlay of equipment.
Be wet flue gas inside when wet cottrell runs, with drop on the insulator that the words that wet flue gas enters insulation room will make insulation room facade, thus can produce creepage phenomenon, equipment cannot work.So in order to prevent insulation indoor from having water smoke, drop, just increase a set of sealing system in the outside of insulation room, before flue gas passes into wet cottrell, the high temperature air higher than wet cottrell internal pressure is blown into insulation room, such wet flue gas would not enter.
So be connected to sealing system outside insulation room 7, sealing system comprises heater 24, pressure transmitter 21, temperature transmitter 22 seal fan 17, described heater 24, seal fan 17 connect successively, wherein heater 24 is connected with insulation room, between insulation room and heater 24, be provided with temperature transmitter 22 and pressure transmitter 21.
Acting as heating insulation room 7 of heater 24, insulation speckles with dust, water smoke or flue gas in room 7, the direct work affecting cleaner, insulation room 7 is cavity structure, and inside is hollow, to heating outside insulation room 7, the drying of insulation room 7 can be kept, do not produce creepage phenomenon.
Bonding pressure transmitter outside insulation room 7, makes the pressure in the cavity of insulation room 7 be greater than the pressure of insulator exterior.
Pressure transmitter 21 monitors the pressure that insulation is indoor, works, ensure to make the pressure of hot blast be greater than the pressure of flue gas if hypotony just starts backup seal blower fan 17.
Temperature transmitter 22 is greater than 100 degree for the hot blast monitoring seal fan 17 and blow out, and makes like this to keep dry in insulation room 7, does not have the liquid such as water droplet and exists.
Embodiment 1
Be composed in series by the wet cottrell of two single-stages, the cathode filament 6 of two one poles is connected by insulator 14, and the cathode filament 6 of two one poles connects electric power system respectively, the cathode filament 6 separate connection power supply of each one pole.Also comprise, lower positive plate group beam, on, lower negative electrode beam, on, lower cathode frame and insulation room 7, positive plate group 8 is in the core position of described wet cottrell, positive plate group about 8 two ends are separately fixed at, on lower positive plate group beam, it is firm that upper negative electrode beam 9 is connected with upper cathode frame 15, cathode filament 6 hangs on cathode frame 15, and ensure that a cathode filament 6 is installed in the center of each positive plate, cathode filament 6 is divided into two sections, connect the upper of insulator 14 respectively, lower end, cathode filament 6 below insulator 14 is strained by lower cathode frame 16, lower negative electrode beam 5 is fixed with the shell of described wet cottrell by insulation room 7, insulation is provided with insulator in room 7, insulator one end connects insulation room 7, one end connects the point of incoming cables of described power supply.
When wet cottrell runs, flue gas enters from gas approach 4, spraying system 3 can be atomized flue gas, acquired by spraying system, fresh water (FW) temperature is below 15 DEG C, spray direction and flue gas direction are forward or reverse, atomization can make granule condense further, thus can improve efficiency of dust collection.After even distribution device 13, after even distribution device is placed on gas approach, effect is to make flue gas be evenly distributed on wet cottrell inside.Its structure has the plate of circular hole one by one, the diameter 100mm of circular hole, and percent opening is about 30%-40%, and uniform thickness of slab 2-20mm, flue gas is evenly distributed in positive plate group 8.Upper and lower two sections of cathode filaments 7 independently power supply control, can, according to actual condition regulation voltage respectively, make efficiency of dust collection optimum.Last flue gas is gone out from exhanst gas outlet 12.In order to ensure that wet cottrell is stable, insulation room sealing system is accessed in the insulation room 7 at electric power incoming line place, the insulation room of insulation room sealing system two-stage cathod system up and down provides pressure 1kPa-10kPa, the air of temperature 50 C-120 DEG C, guarantee insulator surface is dry, does not produce creepage phenomenon.When wet cottrell runs a period of time, positive plate group 8 has certain dust stratification, now, start spray system 10 antianode plate group 8 and cathod system spray irrigation simultaneously.
Although the present invention with preferred embodiment openly as above; but they are not of the present invention for limiting; anyly have the knack of this those skilled in the art; without departing from the spirit and scope of the invention; can make various changes or retouch from working as, what therefore protection scope of the present invention should define with the claims of the application is as the criterion.
