Abstract

The utility model discloses a circular tube cathode barbed wire for an electrostatic precipitator, which has good discharge performance, simple structure, stability and reliability. The cathode barbed wire comprises a circular tube which is taken as the main body of the cathode wire and single-end barbed sheets, wherein the two ends of the circular pipe are squeezed respectively and form connecting plates; and the root parts of the single-end barbed sheets bend to form quarter arcs, and the single-end barbed sheets are welded with the circular pipe and are in cross arrangement on the two surfaces of the circular pipe, or double-end barbed sheets which are bent and have half-arc middle parts are welded with the circular pipe and are in cross arrangement on the two surfaces of the circular pipe. The root parts of the single-end barbed sheets are lengthened to a small extend, bent and taken as auxiliary barbs while the middle parts of the double-end barbed sheets are machined to be small barbs which are taken as auxiliary barbs.

Description

Electric cleaner pipe prickle cathode line

Technical field

The utility model relates to a kind of electric cleaner, relates in particular to a kind of pipe prickle cathode line that is used for electric cleaner.

Background technology

At present the tubular prickle wire of using on the electric cleaner because tubular big, fastness is good, rigidity is strong, strength of discharge is big, uses very extensively, occupies bigger environmental protection market.Its barrel portion is welded by two semicircles and the steel plate that has a wing plate, and this semi-circular plate is made and required to have special-purpose slitting mill earlier roll bending to be cut into steel band, rolls into semi-circular plate with milling train again.Two semi-circular plates be welded into tubular after, also need in two end circular holes, insert pipe and welding, again the pipe that inserts is flattened as connecting plate between it and the cathode frame, this is its weak spot.The last prickle plate of putting the shaping of punching out of burn-oning on wing plate, complex manufacturing adds that materials are more thereby production cost is higher.

The width of tubular prickle wire is big, and is also big with respect to the projected area of positive plate, thereby the capacitance of electric field is big.On the one hand electric capacity makes that greatly the odds ratio of the peak value of voltage waveform of electric field and mean value is less, makes waveform more smooth; The electric energy of electric capacity ambassador electric field storage is big on the other hand, and the impact to rectifier transformer and porcelain insulation spare that the LC vibration causes is also big, and it has negative effect to electric cleaner this respect.

For the electric force lines distribution that makes electric field is more even, in semicanal plate upper punch spinule is arranged, so also cause flue gas to enter cathode line inside and draw into two-sided corrosion, can shorten the life-span of cathode line.

The prototype structure of this tubular prickle wire does not have cathode frame, and vibrating rod is to hang upside down on tubular prickle wire, so its requirement of strength is big especially.Now it has made to have the structure of framework into, and great majority have cathode line linear all more tiny or thiner of framework, and therefore the tubular prickle wire that is installed in the cathode frame there is no need big intensity like this.

Price of steel product and labor cost etc. all increase comparatively fast at present, because the cathode line enormous amount, its production difficulty and cost height are bigger to the economic effect relation.So the deficiency of tubular prickle wire and defective add that the complex manufacturing cost is higher, have weakened its market competitiveness to a certain extent.At present environmental protection industry (epi) press for several existing good discharge effect, production costs lower, the bigger market competitiveness, cathode line that reliability is high arranged.

The utility model content

The technical problems to be solved in the utility model provides the electric cleaner pipe prickle cathode line that a kind of discharge effect is good, production cost is lower, reliability is high.

The utility model is achieved through the following technical solutions:

The utility model comprises round steel pipe or stainless steel tube, and two ends of pipe flatten into flat as the connecting plate that links to each other with cathode frame, pipe and as the main body of cathode line not only as connecting plate safety but also reliably.

The utility model also comprises the prickle plate that is welded on the pipe, and prickle plate divides two kinds of single head prickle plate and double end prickle plates.The root bending of single head prickle plate becomes quadrant arc and pipe welding; The middle bent of double end prickle plate becomes 1/2nd circular arcs and pipe welding.

As preferably, the root proper extension of single head prickle plate can play the effect of auxiliary prickle.The middle part of double end prickle plate dashes a spinule, also can play the effect of auxiliary prickle.Because the mode of these two kinds of auxiliary prickles is not all broken through pipe, can not cause therefore that flue gas enters to cause two-sided corrosion in the pipe favourable raising service life.

The utility model comprises that also the prickle plate that is welded on the pipe is two-sided arranged crosswise, and auxiliary prickle is had at two faces of pipe.

This pipe prickle wire not only can reduce cost but also be connected firmly designs simplification, thereby can guarantee equipment safety operation.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model comprises that as the pipe of cathode line main body (1) two ends of pipe are flattened respectively and formed connecting plate (2).

As shown in figures 1 and 3, the root bending of single head prickle plate (3) becomes quadrant arc and pipe welding, and the prickle plate that is welded on the pipe is two-sided arranged crosswise.

As Fig. 2 and shown in Figure 4, the middle bent of double end prickle plate (4) becomes 1/2nd circular arcs and pipe welding, and the prickle plate that is welded on the pipe is two-sided arranged crosswise.

As shown in Figure 3, the root proper extension of single head prickle plate and crooked as auxiliary prickle (5).

As shown in Figure 4, the middle part of double end prickle plate dashes a little prickle as auxiliary prickle (6).

Claims
