Description

(54) ARE IMPLEMENTED I. ELECTROFILTER

The invention is intended for mining in the metallurgical industry and can be used to clean the ventilation air from the dust supplied to the working areas of mineral processing factories.

The closest to the proposed; An electrostatic precipitator is an electrostatic precipitator with a solid-state precipitating electrode, comprising a housing with a precipitator ephode in the form of a tank filled with water. In the case, a preload system with corona-forming electrodes is installed, emitting in three-dimensional rectangular lines with a rounded corner, pointing to the surface of C11 sedimentation,

The disadvantage of the electrostatic precipitator is the ability to work of the kovstruktshgv without 9n & There are preloads that fly in the active call of the space channel with the observance of the air gap between the cows. aptrodamv in kzbezh & BBej ipo6oa, giving cumbersome cleanliness to the cavalians in the complex

installation In the cleaning channel at 1H) p0zontalno located slugging surface, it is possible to use only one-sided corona electrodes with fixed points of 5 mA $ d, the current-voltage characteristics of which in supply electrofilters are limited by current, as further increase in current through the separation of by-products, pemoi

On Mentvables by Maximum Permissible I-Coordinates. Кр (% 4е addition, when supplying purified air to the room, it contacts the walls of the air ducts, which leads to the deionization of the air;

15 ha, as a result of which the beneficial effect of negative ions on the human body is excluded.

The aim of the invention is to understand the process of dust deposition under

20 by the action of aerodynamic forces in the electric field force, simplifying the design of the CVs, eliminating the formation of harmful by-products during the corona

de otrshshelnoy pop rnostv, maintaining maximally coviecentral aerov vovov in the air and prevented him from detonation.

This ael is achieved by the fact that, in an integrated electrostatic precipitator, including a flow nozzle, a liquid crystal electrode and a system of pressing the flow to be cleaned to the detachable surface with corona-forming electrodes, the preload system is made in the form of an insulated insulated insulated electrode. and the precipitation electrode is placed in the inlet nozzle,

Fig, 1 shows a supply electrostatic precipitator, front view; on. FIG. 2 is the same side view (section A-A in FIG. 1); in fig. 3 a circuit for connecting an electrostatic precipitator to an assembly manifold.

The inlet electrostatic precipitator consists of an inlet nozzle 1, a louvre corona grinder 2, insulators 3 placed in insulator boxes 4, scrapers 5, a booster distributing collector 6, a liquid precipitation electrode 7 and a high-voltage unit (not shown in the figures). I

The electrostatic precipitator works as follows

When high voltage is applied to the louvre corona grill, a corona discharge occurs from the high-voltage power supply unit, under the action of which the dust particles are charged electrically. The air flow to be cleaned contains charged particles with the help of obliquely positioned platters of the louver corona grille to the liquid precipitation electrode, and then under the action of aerodynamic forces, the electric field is the deposition of dust. The trapped dust is removed by continuously draining the water and scrapers,

In the process of corona discharge, the purified air is saturated with negative aeroions, and then supplied to the working places in the form of a jet, formed

nozzle, preventing it from deionization.

The implementation of the electrostatic precipitator according to the invention provide a high

air purification stump with low current corona and high electric field intensity, which prevents the formation of such harmful by-products as ozone and

oxides of nitrogen, with corona discharge of demarcated polarity, and the bezvos is perfidious distribution of the purified air flow prevents its deionization, enriching it with vital

aeroions.

The use of the proposed inlet electrostatic precipitator allows improving the sanitary and hygienic working conditions in factories during the processing of mineral resources.
