The term is a reduction in the size of the electrostatic precipitator.

The drawing shows the proposed electrostatic precipitator,

In the case of the electrostatic precipitator with side walls 1 are located the corona-forming 2 and precipitator 1st 3 electrodes. Koroniruk) 1cie electrode 2 connected to the otritsage. To the pole of the power source 4. The fuse electrodes 3 are grounded and connected to the second pole of the power source 4. A parallel gas propane is installed at the exit from the zero (1e d (additional sedimentation electrode; 5-7 perpendicular to the side walls 1 of the electrostatic precipitator) with a slope to the side out of: 1 at an angle about from the case cover less than or equal to 65 °. Additional negative electrodes 5–7 connect HeiHii with each other through a voltage divider 8. Far from the exit from the floor is an additional (positive 1 | 1 collecting electrode 7 is connected to n (1 plus additional source) (source 9 has power, inero has a positive potential.

The electrostatic precipitator works as follows.

The gas flow enters the electrostatic precipitator body, moves parallel to the side stack} 1kam 1 and passes through the field where the drunk particles receive a negative charge from the corona discharge of the corona-free electrodes 2 and are partially deposited on the precipitation electrode 3 under the action of a non-uniform electric field arising between the corona 2 and osaditelno1,1Mi 3 electrodes-gi. The elusive charged particles HhL Ui) 1.1 come with a gas flow from the field and enter zo-1y with a quasi-uniform electrostatic field arising between the additional gas-permeable collecting electrodes 5.6 and 7.6, since they are interconnected through a divider 8 voltage I, and the electrode 7 is connected to an additional source 9 power.

Since the additional 11: precipitation precipitation electrode 6 is connected to an additional precipittel) n1.1m electrode 7 through a voltage divider 8, then

It establishes a non-personal potential for each of the alternators than on the additional precipitation electrode 7, which is connected to an additional source of electrical power 9 in a straight line. Therefore, the direction of the intensity vector to the 5-one electrostatic field, caused by the electrodes between the electrodes 6 and 7, coincides

With the direction of movement of the gas flow and at the same time) the first particles of dust are additional) 1 ° to the Coulomb force of the electric field, the force of the hydraulic pressure of the gas flow. A similar process takes place in the zone between the additional collecting electrodes 5 and 6, where the voltage is set to the voltage set by the potential of the electrode 5

smaller than electrode 6, and in this case the vectoring of vectors (1p of the intensity of a quasi-uniform electrostatic zero coincides with the direction of motion of the pie-gas flow. The potential

additional precipitation electrode 5 has a sign opposite to the potential of the corona electrodes 2 and is larger in magnitude than the potential grounded} of the first precipitation

electrodes 3, therefore, near its surface, a quasi-uniform electrostatic field is formed, the direction of which vector coincides with the direction of movement of the piezo-gas flow.

The change in (; the potential of the additional power source 9, as well as the division ratio of the voltage divider 8) regulates the impersonal strength of a quasihomogeneous electrostatic field between the additional, gmi. Electrodes 5.6 and 6.7. Since the velocity of the dust-azov v and the direction of the force vector of the electrostatic field, the kotstra moves the dust particles and the precipitating surface at a speed Vj, sovnadamtt, then the total} 1n drift velocity of the part pipi v increases by the velocity component

At such an inclination angle, large lumps of the slips do not have time to pass the 1 –p 1 permissible additional electrodes that fall from the top of the bottom to the lower edges of the additional slugging electrodes 5–7 and are not carried away by their flow beyond their limits. PCE reduces dust removal from the electrophile.
