Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This case relates to the online blockage-clearing device of a kind of wet-esp nozzle, as shown in Figure 1-2, mainly includes pipeline 1 and is located at the Venturi tube 2(ejector on this pipeline 1), the first valve member 3 and the second valve member 4.
Pipeline 1 has a main road 10 and three branch roads.One end of main road 10 forms entrance 101.Article three, branch road all connects and is located on main road 10, is respectively the first branch road 11, second branch road 12 and the 3rd branch road 13.This first branch road 11 converges mutually with the free end of the second branch road 12, and the free end of the pipeline that this meet extends forms jet hole 121, installs for nozzle M.The free end of the 3rd branch road 13 is block clearing outlet 131.
Venturi tube 2 is located at the junction of the first branch road 11 and main road 10, and the adsorbent chamber entrance of Venturi tube 2 is aimed at the first branch road 11 and arranged.First valve member 3, second valve member 4 is located on the second branch road 12, the 3rd branch road 13 respectively.Online blockage-clearing device also includes control pressurer system 5, and it is for detecting the pressure suffered by jet hole 121 place nozzle M, and corresponding control first valve member 3 and the second valve member 4 are opened or shutoff operation respectively.
Described control pressurer system 5, basis is novel provides a specific embodiment, and its main element is be located at the other pressure switch 51 of jet hole 121.First valve member 3, second valve member 4 is electric control element.Detect pressure in jet hole 121 by pressure switch 51 and automatically control the break-make of the power supply of the first valve member 3, second valve member 4, thus realizing control first valve member 3, second valve member 4 and open respectively or closing motion.Further, described first valve member 3 preferably adopts normally open solenoid valve, and the second valve member 4 adopts normally closed solenoid valve.Certain control pressurer system 5 is except adopting the automatically controlled mode of pressure switch, other modes such as Mechanical course can also be adopted, first, second valve member, except adopting electric control element, also can use mechanical organ, as long as can realize detecting nozzle pressure and making associated branch break-make controls.
Preferably, control pressurer system 5 is also provided with Pressure gauge 52, and this Pressure gauge 52 is located on main road 10.By this pressure gauge 52, operator can understand pipeline pressure situation, and more crucial is indicated by the pressure of this pressure gauge 52, helps the operating pressure of set pressure switch 51, namely plays pressure when indirect labor's set pressure control system 5 works.
When nozzle M normally works, pass course as shown in phantom in Figure 3, first valve member 3(normally open solenoid valve) place's open mode, and the second valve member 4(normally closed solenoid valve) place's closed condition, from entrance 101, through main road 10 flow through the second branch road 12 and on the first valve member 3, finally spray from nozzle M.When nozzle M is filled in stifled, overpressure increases, and detected by control pressurer system 5 and control, the first valve member 3 is closed, and the second valve member 4 is opened.Pass course as shown in phantom in Figure 4, utilizes the negative pressure that Venturi effect produces, make plug block up thing from nozzle M through the first branch road 11 and by Venturi tube 2 after, again through main road 10, flow to the 3rd branch road 13, by the second valve member 4 opened, finally flow out from block clearing outlet 131.When overpressure gets back to normal value, automatically adjust through control pressurer system, make the first valve member 3 recover to open, the second valve member 4 recovers to close, and finally makes nozzle M work on.
Described pressure switch 51, as the switch of control pressurer system 5, directly controls the first valve member 3, second valve member 4 break-make.This kind of mode is applicable to common atomizer, and when filling in stifled thing and being jammed in jet hole because of shape, pressure switch 51 acts on, and produces moment negative pressure in nozzle, and the stifled thing of plug is impacted defeated and dispersed, is convenient to flow out from jet hole.Preferably, described control pressurer system 5 also can be provided with delay cut-off module (not shown), this delay cut-off module is specifically as follows delay cut-off relay, it is connected electrically between pressure switch 51 and the first valve member 3, second valve member 4, for controlling this first valve member 3, second valve member 4 delay cut-off effect.This kind of mode is applicable to finer atomization nozzle, when filling in stifled thing and cannot flowing out from jet hole, delay cut-off module the delayed-breaking-off function that rises negative pressure can be made to continue generation, the plug in nozzle is blocked up thing suck-back, be beneficial to tamper bleeder, realize excellent block clearing effect.
Preferably, the first branch road 11 is also provided with check valve 6, the one-way flow direction of this check valve 6 is towards the direction of Venturi tube 2 side.Check valve 6 is for when nozzle M normally works, and prevents negative pressure and may affect the effect of nozzle operation.
Preferably, block clearing outlet 131 extends near jet hole 121(nozzle) arrange.In this in blocking cleaning work time, the water that can be discharged of block clearing outlet 131 spray to nozzle, for the air that alternative nozzle goes from extraneous inspiration, to improve block clearing effect.
Preferably, described entrance 101 is other is also provided with safety valve 7, plays safety protection function.
Preferably, described online blockage-clearing device is also configured with an airtight device case 8, and pipeline 1 and upper-part thereof are installed with in device case 8, to improve the stability of whole device.For the ease of connecting, the entrance 101 of pipeline 1, jet hole 121 and block clearing export outside 131 extending apparatus housings 8.In specific design, the first valve member 3 and the second valve member 4 also exposing device housing 8, be beneficial to electric wire and connect; Device case 8 corresponding pressure switch 51 place offers string holes, is convenient to connect outside the connecting line 511 extending apparatus housing 8 being beneficial to pressure switch 51.
This novel online blockage-clearing device utilize first, second valve member open with close do not stop automatic conversion, realize the block clearing of on-line automaticization in not blowing out situation, automatic adjustment after block clearing completes, makes nozzle work on; And the water source of nozzle and block clearing outlet is all from the water of entrance, the online block clearing of device is without the need to extra power source; Compare Traditional Man block clearing mode, not only increase wet electrical dust precipitator performance, but also greatly improve bringing benefits of wet electrical dust precipitator, greatly reduce manufacturing cost, thus achieve the possibility of batch production.In addition, this novel online blockage-clearing device uses medium to be not only confined to aqueous water, and gas medium is feasible too.
The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
