An electrostatic precipitator comprises a shell, an anode, a cathode tube, an air inlet and an air outlet, and is characterized in that the air inlet is arranged at the top end of the side face of the shell, and the air outlet is arranged at the bottom end of the side face of the shell. The utility model provides an electrostatic precipitator, it has changed traditional fluid passage and has advanced the layout mode of going out from top down, make dirty air get into from electrostatic precipitator's top, clean air is discharged from electrostatic precipitator's bottom, air current thrust is unanimous with collection dirt direction of gravity, thereby promote to make album dirt descend along the cathode tube inner wall, in addition rivers thrust during the washing, reach the cleaning performance very conveniently, compare with traditional electrostatic precipitator and have better dust removal effect, equipment cleaning is also more convenient and thorough, thereby electrostatic precipitator's life has been increased, the fortune dimension cost is reduced.
Description
Technical Field
The utility model belongs to the technical field of dust collecting equipment, concretely relates to electrostatic precipitator.
Background
The working principle of the electrostatic dust collector is that a high-voltage electric field is utilized to ionize smoke, so that dust charges in airflow are separated from the airflow under the action of the electric field. The electrostatic precipitator may be classified into a wet electrostatic precipitator and a dry electrostatic precipitator. Because the wet electrostatic precipitator is additionally provided with the spraying system and the water supply and drainage system for supplying water to the spraying ash removal system, compared with other dust removal equipment, the wet electrostatic precipitator has the characteristics of low energy consumption, high dust removal efficiency, low pressure loss, no secondary dust raising and the like. In addition, the wet electrostatic precipitator can be divided into a cross flow type (horizontal type) and a vertical type (vertical type) according to the flow direction of waste gas, the cross flow type is mostly of a plate type structure, the gas flow direction is in and out in the horizontal direction, and the structure is similar to that of a dry type electrostatic precipitator; vertical flow is mostly tubular structure, and the gas flow direction is the vertical direction business turn over.
SUMMERY OF THE UTILITY MODEL
Because of the restriction of service condition, the fluid passage of vertical flow formula wet electrostatic precipitator all adopts the mode overall arrangement of advancing from bottom to top on the existing market, but the air current gets into the cleanliness when the top is discharged and can seriously influence equipment washing from the below, because of air current direction and collection dirt gravity opposite direction, sometimes air current thrust is greater than collection dirt gravity, lead to collecting dirt from this and climb and assemble in the cathode tube top along the cathode tube inner wall, when accumulating to a certain extent, form consistent dense insulating layer in other words, wash and can't get rid of, thereby lead to dust removal effect greatly reduced. In view of the above problem, the utility model provides an electrostatic precipitator, it has changed traditional fluid passage and has advanced the layout mode of going out from top to bottom, make dirty air get into from electrostatic precipitator's top, clean air is discharged from electrostatic precipitator's bottom, air current thrust is unanimous with collection dirt direction of gravity, thereby promote to make album dirt descend along the cathode tube inner wall, in addition rivers thrust during the washing, reach the cleaning performance very conveniently, compare with traditional electrostatic precipitator and have better dust removal effect, equipment washs also more conveniently and thoroughly, thereby electrostatic precipitator's life has been increased, the fortune dimension cost has been reduced.
The utility model discloses a following technical scheme realizes.
An electrostatic precipitator comprises a shell, an anode, a cathode tube, an air inlet and an air outlet, and is characterized in that the air inlet is arranged at the top end of the side face of the shell, and the air outlet is arranged at the bottom end of the side face of the shell.
As a preferred technical scheme, a heat preservation chamber is arranged at the top end of the shell, and a constant-temperature heating device is arranged in the heat preservation chamber; the insulating porcelain bushing of the anode is accommodated in the heat preservation chamber.
The utility model has the advantages that: the utility model discloses a change the fluid passage of traditional electrostatic precipitator and advance the layout mode of going out from top down, make dirty air get into from electrostatic precipitator's top, clean air is discharged from electrostatic precipitator's bottom, compare with traditional electrostatic precipitator and have better dust removal effect, equipment washs also more conveniently and thoroughly, has reduced the cleaning water consumption and has washd the frequency, thereby the water resource has been practiced thrift greatly, the requirement of follow-up technology to waste water treatment has also been alleviateed, fortune dimension cost has been reduced.
Drawings
FIG. 1 is a schematic structural view of an electrostatic precipitator according to the present invention;
the meanings of the marks in the above figures are as follows: 1-shell, 2-anode, 21-insulating porcelain bushing, 3-cathode tube, 4-air inlet, 5-air outlet, 6-heat preservation chamber, 7-power supply, 8-constant temperature heating device, 81-heating element and 82-constant temperature controller.
Detailed Description
The present invention is further described in the following embodiments with reference to the attached drawings, and it should be noted that the following embodiments are only illustrative of the present invention by way of example, but the scope of the present invention is not limited thereto, and all those skilled in the art can substitute the equivalent of the present invention by the spirit of the present invention.
Examples
Referring to fig. 1, an electrostatic precipitator includes a housing 1, an anode 2, a cathode tube 3, an air inlet 4, and an air outlet 5, wherein the air inlet 3 is disposed at the top end of the side surface of the housing 1, and the air outlet 5 is disposed at the bottom end of the side surface of the housing 1; in the above-mentioned structure, dirty air gets into from electrostatic precipitator's top, and clean air is discharged from electrostatic precipitator's bottom, compares with traditional electrostatic precipitator and has better dust removal effect.
Because the dust-containing air enters from the top end of the electrostatic dust collector, and the electrostatic dust collector is usually provided with a spraying system, the dust-containing flue gas is usually saturated wet flue gas, and under the condition that the anode 2 is not tightly sealed, water vapor in the saturated wet flue gas is easily condensed into water drops to be contacted with the insulating porcelain bushing 21 of the anode 2, so that the insulating porcelain bushing 21 is burst to generate potential safety hazard; further, in a preferred embodiment, referring to fig. 1, a holding chamber 6 is provided at the top end of the housing 1, a constant temperature heating device 8 is provided inside the holding chamber 6, and the constant temperature heating device 8 includes an electric heating element 81 and a constant temperature controller 82; the insulating porcelain bushing 21 of the anode 2 is accommodated in the heat preservation chamber 6, so that the inside of the heat preservation chamber 6 can maintain a higher constant temperature, and therefore, water vapor entering the heat preservation chamber 6 cannot be condensed to contact with the insulating porcelain bushing 21, and the insulating porcelain bushing 21 is always kept in a dry state.
