Description

Electrostatic precipitator
Technical field
The present invention relates to a kind of electrostatic precipitator that is used to remove the industrial fumes particle, especially can effectively overcome the electrostatic precipitator of reentrainment of dust.
Background technology
Existing electrostatic precipitator, be cathode line to be installed cooperate many sedimentation passages of forming with enclosed positive plate in the casing of deduster, gas parallel cathode lines and positive plate pass through, on cathode line, apply the negative high voltage direct current, make its ionized gas produce negative particle, flue dust is charged and be adsorbed on the positive plate in flowing through the way, comes off by rapping apparatus, thereby reaches the purpose of removing smoke particle in the gas.
Yet existing electrostatic precipitator has the following disadvantages: flue dust can not in-plantly paste positive plate and flow through, from charged to absorption, the flue dust one section quite long parabola distance of will flowing through, if positive plate is too short, it just captures less than flue dust, thereby along with air-flow is discharged.
It is very big that above defective makes that electrostatic precipitator will reach the following difficulty of state emission standard 50mg/Nm3, adopt at present widen, traditional means inputs such as lengthening, increasing are very big and effect is also undesirable, facts have proved that its effect is local and limited.
In order to overcome existing electrostatic precipitator defective, save social resources, the call of active response country energy-saving and emission-reduction thoroughly improves air quality.The invention provides the electrostatic precipitator that a kind of structure is internally transformed.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides following a kind of electrostatic precipitator, comprise casing, the casing two ends are respectively equipped with air inlet and exhaust outlet, be provided with some cathode line, positive plate and cathode line rapping apparatus in the casing, cathode line links to each other with the cathode line rapping apparatus, and cathode line is parallel with positive plate, and positive plate comprises some control of dust sheets;
The air inlet place is interval with some gas-flow deflectors perpendicular to the casing axis, be provided with the air intake passage baffle plate between the adjacent gas-flow deflector, gas-flow deflector comprises some prerotation vanes that are the splayed symmetrical distribution along its center line, gas-flow deflector and air intake passage baffle plate are in the same plane generally, and gas-flow deflector and positive plate are arranged vertically;
Positive plate comprises first anode plate and second plate plate, plane, the whole place of the control of dust sheet of first anode plate becomes positive acute angle with the casing axis, plane, the whole place of the control of dust sheet of second plate plate becomes to bear acute angle with the casing axis, and the two ends of first anode plate and second plate plate link to each other with the exhaust port passageways baffle plate with gas-flow deflector respectively.
As a kind of improvement, described cathode line upper end is fixed on the casing top frame, and it is unsettled that the lower end connects weight.
As further improvement, described cathode line comprises at least two negative electrode line segments, and adjacent two negative electrode line segments fixedly are connected with the suspension lock respectively, hangs lock and is located on the trip rod; Hang the whole one-tenth of lock tubulose, two ends are respectively equipped with installing hole up and down, and negative electrode line segment upper and lower is respectively equipped with through hole, and adjacent two negative electrode line segments weld together.
As further improvement, the switch of described cathode line rapping apparatus is a single-pole double-throw switch (SPDT), and the common port of switch connects cathode line, and all the other two ends connect transformer and earth terminal respectively.
As further improvement, described control of dust sheet is made up of W shape folding surface and the guide surface that is positioned at the folding surface two ends.
As further improvement, described prerotation vane is made up of curved guiding surface and the guide surface that is positioned at the curved guiding surface two ends.
As further improvement, the guide surface of described control of dust sheet becomes positive 55 degree angles or negative 55 degree angles with the casing axis.
As further improvement, the guide surface of described prerotation vane becomes positive 12 degree angles or negative 12 degree angles with the casing axis.
As further improvement, described suspension lock middle part offers welding hole.
As further improvement, described weight comprises the mounting pipe of top hollow and the hammer body of bottom, offers installing hole on the mounting pipe.
Electrostatic precipitator of the present invention, gas passes through the positive plate of flowing through after gas-flow deflector leads, discharge from exhaust outlet at last, since gas-flow deflector and positive plate all with the casing axis at an angle, make gas flow S-shaped on the whole, make the straight-through reentrainment of dust problem that is easy to produce of air-flow in the past to overcome; Such structure to prolong gas time of in electrostatic precipitator, being detained, make that flue dust can be fully charged and can press close to positive plate and flow through, the absorption distance is short; And the control of dust sheet with W shape folding surface is compared than the positive plate of original single plane shape and has been increased specific collection area.
Cathode line was to be fixed on the whole cathode frame in the past, so be to beat on cathode frame in the time of rapping, because the scope that rapping power is transmitted is wide, the part causes anode line stressed little and inhomogeneous, the space of neither one oneself vibration, can only do quiver according to framework, so cathode line is difficult to clean out usually, for this reason that the cathode line bottom is unsettled by weight, the not straight problem of cathode line extension can thoroughly solve in the past, be convenient to install and adjust, drive the cathode line vibration by the rapping trip rod, making to have enough spaces to produce vibration when every cathode line receives rapping power, cathode line just is easy to clean out like this, helps more effectively producing corona voltage.
Cathode line all was charged rapping in the past, even adopt the comparatively advanced voltage rapping mode of falling, the voltage of 20-30kV was arranged still on the cathode line, was extremely difficult so want flue dust positively charged on the cathode line is cleaned out.We adopt cathode line ground connection rapping mode for this reason, during rapping cathode line is connected with earth terminal, negative high voltage and the charged flue dust stayed like this on the cathode line can discharge fully over the ground, again by above-mentioned cathode rapping method, flue dust on the cathode line just can have been cleaned out fully so, can too much not influence the fully saturated of secondary voltage and secondary current, avoid too much causing voltage and the serious waste of electric current because of flue dust on the cathode line because of flue dust on the cathode line.
Adopt the electrostatic precipitator of technical scheme of the present invention in sum, experimental results show that smoke dust discharge concentration effectively is controlled at below the 1mg/Nm3.
