Technical field
The present invention relates to the cleaning of wet cottrell dust collecting pole plate, be specifically related to a kind of dust collecting pole plate and clean the equal method of completing the square of water.
Technical background
Dust collecting pole plate is mainly used in the electrostatic precipitator of field of Environment Protection, the difference according to technical scheme, and the form of dust collecting pole plate, kind and purge mode are different. Difference according to purge mode, electrostatic precipitator is typically divided into wet cottrell and the big class of dry electrostatic cleaner two. Wet cottrell its be mainly used to remove containing harmful substances such as the dust in humid gas, acid mist, drop, aerosol, PM2.5, in each industrial processes, have extensive application. Being different from the mode of dry electrostatic cleaner vibration dust-cleaning, what wet cottrell adopted is the mode of current flushing, makes dust remove along with the flowing of cleanout fluid. The cleaning way of wet cottrell dust collecting pole plate also has multiple, wherein mainly has employing nozzle spray mode clean and adopt non-fountains such as dripping pouring or spillway to clean.
The wet cottrell dripping the non-fountain pole plate cleaning ways such as pouring or spillway has the distinguishing features such as dust collecting pole plate moisture film is uniform, it is thorough to clean, efficient energy-saving, stable, purification efficiency is high, gets more and more in state, inside and outside application. But, along with being on the increase of engineer applied, also expose some problems, be concentrated mainly on dust collecting pole plate because of hydropenia premature corrosion failure, the aspect such as specific collection area reduces relatively, purification efficiency die-offs, mainly dust collecting pole plate of tracing it to its cause cleans moisture and joins inequality. Its root is mainly concerned with following aspect: one is cleaning water system multiple branch circuit, and water circuit system mostly is DRS formula, adopts total head way of supplying water, regulates difficulty big. Two is after blocking occurs in purging system, it is difficult to is changed by the pressure reduction of system and judges.

Described distribution at static pressure is provided with water level transparent tube on pipe, is known the water supply condition of each branch road of pipe network by the liquid level instruction of transparent tube and the stability of liquid level, it is judged that whether each branch road blocks during operation.
The described outlet at water-supply-pipe is provided with the static pressure distribution pipe of level and carries out constant voltage and the uniform distribution of each branch road discharge, is provided with restricting orifice on each vertical leg pipe that dust collecting pole plate cleans water.
In technique scheme:
The present invention realizes stablizing of flow in water-supply-pipe by flow transmitter, automatic regulating valve, static pressure distribution pipe and the synergism of restricting orifice. Automatic regulating valve is coupled control with flow transmitter and coordinates by the method, carries out the fluctuation of flow in flow real-time tracking and monitoring water-supply-pipe, and directly drives automatic regulating valve to carry out aperture adjustment flow feedback signal, it is achieved the constant flux control of system; Static pressure distribution pipe can provide bigger water body to hold space, has the effect of voltage stabilizing and shunting; It is arranged at the restricting orifice II on static pressure distribution pipe downstream leg pipe, water flow in static pressure distribution pipe is adjusted, owing to the aperture of each restricting orifice II is consistent, so under hydrostatic pressure, the water flow eventually through each restricting orifice II is equal; The cleaning water quantity exchange distribution of each dust collecting pole plate is realized in the way of static pressure is all joined.
The invention has the beneficial effects as follows: one, realize cleaning pipe network water yield equilibrium assignment. Owing to adopting the principle and method that constant flow regulates, expenditure and pressure and static pressure are all joined, effectively ensure to clean water and uniformly, be stably assigned to each pole plate and rinse bypass duct, it is ensured that dust collecting pole plate cleans the uniform, sufficient and stable of the water yield. Two, operation stability is good. The present invention can effectively overcome network of rivers fluctuation that end is cleaned the influence of fluctuations that the water yield causes, and meanwhile, passes through Multi-regulation, it is ensured that each dust collecting pole plate cleans the equalization stable of the water yield. Three, there is simple, practical, reliable and stable feature. Of the present invention is common flow transmitter, automatic regulating valve, restricting orifice and static pressure distribution pipe, flow feedback signal is controlled automatic regulating valve and carries out aperture adjustment, balance ductwork pressure, carry out the constant flux control of system; Utilize throttle orifice to carry out decompression of damming, to eliminate the impact of dynamic pressure, form effect of static pressure equilibrium shunting.

As it is shown in figure 1, arrange big volume static pressure distribution pipe (6), make each water supply bypass duct be in identical pressure of supply water state, be simultaneously used for each dust collecting pole plate and clean the assignment of traffic of bypass duct.
As shown in Figure 1, static pressure distribution pipe (6) arranges transparent pressure instruction pipe (5), whether the pressure that can grasp static pressure distribution pipe (6) by observing its liquid level to indicate is normal, judges that each dust collecting pole plate cleans whether bypass duct the abnormal conditions such as blocking occurs. When the liquid level in transparent pressure instruction pipe (5) is substantially raised, branch road pipe network is described it may happen that block; Otherwise, when its liquid level substantially reduces, whole pipe network is described it may happen that underfed or occur in that system leak.
As in figure 2 it is shown, arrange restricting orifice I (4) on water-supply-pipe (3), its throttle diameter is much smaller than the actual internal area of water-supply-pipe (3). Its effect is the hydraulic pressure reducing and cleaning water, and effectively eliminates dynamic pressure interference. Meanwhile, the water outlet liquid level after regulating and guarantee throttling keeps certain distance h with restricting orifice I (4) so that each dust collecting pole plate cleans bypass duct current and carries out equilibrium assignment in static pressure mode. Restricting orifice I (4) should and dust collecting pole plate top drip and keep enough height difference H between shower pipe (8), its pore size and height difference H can be determined by after calculating and testing.
As shown in Figure 2, each dust collecting pole plate in static pressure distribution pipe (6) downstream cleans and arranges restricting orifice II (7) in bypass duct, the adjustment that its effect is balanced is flowed into each dust collecting pole plate top from static pressure distribution pipe (6) and drips the water flow of shower pipe (8), and its pore size cleans discharge according to the design of each branch road dust collecting pole plate and arranges or regulate.
