Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

It should be understood that the terms "upper", "lower", "left", "right", "middle" and "one" used herein are for clarity of description, and are not intended to limit the scope of the invention, but rather the scope of the invention.

Fig. 1 is a schematic structural diagram of a wet electric precipitator of the present invention, wherein the wet electric precipitator includes a precipitator body 1, a discharge electrode 2 disposed in the precipitator body 1, a dust collecting electrode 3, a spraying device, etc.; the lower part of the dust remover body 1 is provided with an air inlet, the top is provided with an air outlet, and the bottom is provided with an ash discharge port.

As shown in figure 1, the discharge electrode 2 discharges continuously, the dust-containing gas enters the lower part of the dust collector body 11, the dust is attached to the dust collecting electrode 3 through a continuous electric field channel formed by the discharge electrode 22 and the dust collecting electrode 3, the dust and the gas are separated, and the purified gas flows out through a top outlet. According to actual production requirements, after dust is accumulated to a certain thickness or continuously collects dust for a certain time, a control valve 8 on a water supply main pipe is opened, water flows through a spraying branch pipe arranged above a discharge line, and then water mist is sprayed out from nozzles on the branch pipe to finish the dust cleaning operation. And after the cleaning is finished, closing the water supply mother pipe valve, and finishing the primary spraying. Therefore, the working system of continuous discharge, continuous dust collection and periodic intermittent spraying of the wet electric dust collector is realized.

Wherein, spray set is including supplying water female pipe 4, spray branch pipe 5 and nozzle 6, spray branch pipe 5 is connected with supplying water female pipe 4, nozzle 6 is installed on spray branch pipe 5, traditional spray branch pipe 5 arranges for the level, to being interrupted spraying, suddenly stop spraying the back, the water yield reduces in the spray branch pipe 5, the unable thin water smoke of blowout of nozzle 6 under this condition, when ponding is under the continuous waterline in spray branch pipe 5, easily link to each other with the negative pole line (discharge electrode 2 polar line) under spray branch pipe 5 end, when discharge electrode 2 is in discharge state, cause short-circuit fault. In this embodiment, the shower branch pipes 5 are arranged obliquely with respect to the horizontal direction, and the ends B of the shower branch pipes 5 are higher than the positions a where the shower branch pipes 5 are led out from the water supply main pipe 4. Because the tail end B of the spray branch pipe 5 is higher than the leading-out point A of the spray branch pipe 5 from the water supply main pipe 4 (namely the joint of the spray branch pipe 5 and the water supply main pipe 4), accumulated water remained in the spray branch pipe 5 is gathered at one side of the leading-out point A, and no accumulated water exists at the tail end B of the spray branch pipe 5, the short circuit fault caused by the formation of a continuous waterline at the discharge electrode line and the tail end of the spray branch pipe 5 is avoided, so that the reliability and the safety of the energy-saving and environment-friendly wet electric dust collector with continuous discharge and intermittent spray are improved.

Referring to fig. 2, the included angle between the spraying branch pipe 5 and the horizontal direction is 3-20 degrees, the spraying effect is affected by too large included angle, and water flows out from the tail end of the spraying branch pipe 5 when the included angle is too small.

Wherein, be provided with control valve 8 on the water supply main pipe 4 for control whole water route break-make, be provided with 1 to a plurality of nozzle 6 on every spray branch pipe 5.

The spraying branch pipes 5 are multiple, and the directions of the spraying branch pipes 5 are the same or different, namely the spraying branch pipes are arranged in parallel or not in parallel. The spray branch pipes 5 on both sides of the water supply main pipe 4 can be symmetrically arranged, and the directions of the spray branch pipes 5 on both sides are different.

As shown in fig. 3, the spray branch pipe 5 is provided with an access opening 7 for facilitating periodic cleaning of deposited scale and dust and mud.

In this case, the access opening 7 is located close to the point where the shower branch pipe 5 leads out of the water supply main pipe 4.

Specifically, each spray branch pipe 5 is formed by connecting at least two sections, the adjacent two sections are connected through a flange and a bolt and sealed through a sealing ring, and the connecting part of the flange forms the access hole 7. The two sections are connected through the flange plate, so that the disassembly and the assembly during maintenance are convenient.

Fig. 1 shows the arrangement of the spray device above the discharge electrode 2, i.e. the water supply main pipe 4 and the spray branch pipe 5 are both above the discharge electrode 2. Of course, it is also possible to position only the shower manifold 5 above the discharge electrode 2.

Fig. 4 shows an arrangement in which the spray device is located in the discharge electrode 2, and may be disposed in the upper, middle or lower portion of the discharge electrode 2. As long as the lowest position of the shower branch pipe 5 is ensured to be higher than the lowest position of the discharge electrode 2.

The discharge electrode 2 comprises a frame and cathode lines arranged on the frame, and the spray branch pipes 5 are positioned in the spacing areas between the cathode lines in the transverse position; between the upper end of the discharge electrode 2 and the lower end frame 21 in the vertical position.

As above, the utility model discloses, because 5 terminal being higher than spray branch 5 from the female pipe 4's of supplying water point of drawing forth of spray branch 5, remaining ponding gathering in spray branch 5 is drawing forth a little one side, 5 terminal no ponding of spray branch have avoided forming continuous waterline and the short-circuit fault who causes at discharge wire and 5 terminal of spray branch to improved in succession discharge, be interrupted the reliability and the security of the energy-concerving and environment-protective type wet electric dust remover who sprays.
