Detailed description of the invention
Be described in detail to characteristic sum principle of the present invention below in conjunction with accompanying drawing 1-3, illustrated embodiment, only for explaining the present invention, not limits protection scope of the present invention with this.
As shown in Figure 1, this invention comprises multiple (two and two or more) electric field in parallel, the corresponding rinsing area of each electric field.According to system size and the given confluent of both sides' contract engagement, in subregion, wait Division rinsing area as far as possible.As 1# electric field corresponds to the 1st rinsing area, 2# electric field is the 2nd rinsing area, 3 electric fields are the 3rd rinsing area, 4 electric fields are the 4th rinsing area ... like this pipeline layout and regulate industrial flushing water to splash baffle plate time convenient unified layout install, also save installation period while ensureing the independent flushing effect of each rinsing area.
Each rinsing area, on the outer same annulus line of tower, described annulus line is provided with each rinsing area correspondence and is provided with independently electrically operated valve, each electrically operated valve and controller Electricity Federation and the start and stop that link mutually.When occurring that flushing fault or all rinsing areas do not need to rinse, controller sends control signal and cuts out by water pump.Such as, when the 2nd rinsing area needs to rinse, the first rinsing area is closed the electrically operated valve that the 2nd rinsing area is corresponding simultaneously and is opened, and other each rinsing area internal electric fields normally run.
All rinsing areas share a flush box, and the industrial flushing water in flush box is pressurizeed by the flush water pump be communicated with flush box and is passed in flushing pipe.Described flush box is provided with two flush water pumps for subsequent use each other, and one as main pump, another is as stand-by pump, and the operating console of controller is provided with the select button of two flush water pumps.During without exception and special circumstances, main pump work, stand-by pump is out of service for subsequent use; When main pump breaks down, normally work and flushing to rinsing area to not delay and affecting electric field, close main pump, open stand-by pump, avoid the man-hour that the overall shutdown of electric field is changed needed for pump, improve operating efficiency, ensure that the timely flushing of rinsing area.
The moisturizing electrically operated valve that low water level opens moisturizing, high water level is closed is provided with in flush box.When the liquid level of the industrial flushing water of flush box is lower than low water level setting value, moisturizing electrically operated valve is opened and supplement industrial flushing water in flush box, ensures the consumption of industrial flushing water in flush box.When the liquid level of the industrial flushing water of flush box is higher than high water level setting value, moisturizing electrically operated valve is closed and is stopped supplementing industrial flushing water in flush box.Open moisturizing electrically operated valve before flush water pump starts, to minimum liquid level signal, open flush water pump execution and rinse automatically controlled logic, moisturizing electrically operated valve opened by interlocking simultaneously.After flushing, the paramount water level settings value of moisturizing is rinse in the lower cycle to prepare.
As shown in Figure 2 and Figure 3, described flushing pipe is positioned at above the electric field of wet cottrell, and to distribute whole rinsing area according to nozzle location.Described flushing pipe comprises main flushing pipe 1 and branch's flushing pipe 2, and the water inlet end of described branch's flushing pipe is positioned at the top of main flushing pipe and is communicated with main flushing pipe, and the top of branch's flushing pipe is higher than main flushing pipe.Turn under 180 °, J type pipeline and be connected to and the pipe baseplane of main flushing pipe or lower position.Only have in branch's flushing pipe and flooding nozzle and have a small amount of water after this programme stops rinsing, can emptying fast in 2 ~ 5 seconds after stopping rinsing, prevent the water in pipeline along continuing water clock always, save water discharge time most 1 hour.
The water outlet end of branch's flushing pipe is provided with square flooding nozzle 3, and flooding nozzle and branch's flushing pipe silk connect.For adapting to the edge shape of rinsing area, be square flooding nozzle by described flooding nozzle, effective spraying area border external boundary is adjustable, only has few fluid spills outside border, and circulation latus rectum also prevent spray nozzle clogging etc. greatly.Described flooding nozzle is made up of the base be connected with cleaning hose, adjustable ball nozzle and locking nut.Adjustable spherojoint makes nozzle have position adjustable, for controlling injection direction more accurately
Be provided with one-level division board 4 above negative electrode girder below flooding nozzle, the edge annular of the corresponding each rinsing area of one-level division board is arranged, and makes the splash droplet beyond flushing frontier district all be isolated in effective rinsing area;
Anode tube is provided with secondary division board 5 between plane adjacent electric field, and the edge annular of the corresponding each rinsing area of secondary division board is arranged.The drop of isolation because of the splashing of negative electrode girder and the flowing of adjacent electric field plane current, realize the isolation between space, rinsing area.Described one-level division board and the height of secondary division board are 200mm.
Further, on described each rinsing area, the corresponding electrically operated valve arranged is arranged on main flushing pipe corresponding to each rinsing area.
This system is applicable to the flushing of multi partition in all big-and-middle-sized electric fields, adopts adjustable square nozzle and space isolation technology after subregion, one-level division board, makes the splash droplet beyond flushing frontier district all be isolated in effective rinsing area; Secondary division board, isolates the drop because negative electrode girder splashes and the flowing of adjacent electric field plane current, realizes the isolation between space, rinsing area.Prevent the gas explosion splash droplet because nozzle vent place is formed, realize the isolation technology in the adjustable space of low cost, play important enthusiasm effect to the full-time emission compliance of current domestic wet-esp.
Be applicable to the smoke gas treatment of the large exhaust gas volumn of the sintering machine of two electric fields and above large-sized station boiler flue gas and steel industry, pelletizing, cement and the industry such as chemical industry and nonferrous smelting.Minimum discharge transformation is carried out to existing power plant, steel mill, all the period of time ultralow qualified discharge that real realization country is existing, also save duration and construction cost simultaneously.
Avoid adjacent electric field when electric field rinses must have a power failure, rinse interface and isolate the gas explosion splash droplet preventing High-Pressure Water from being formed, when preventing flushing, adjacent electric field causes short circuit accident because of splashing current.All electric fields just share set of system cost to be reduced, and rinses and terminate the rear stand-by period and greatly shorten, and flue gas developing result is good, emission compliance.
Above-described embodiment is only the description carried out the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; relevant technical staff in the field, to various distortion of the present invention and improvement, all should expand in the determined protection domain of claims of the present invention.
