Electrostatic dust catcher with front large-particle dust removal

Abstract

The invention provides an electrostatic dust catcher with front large-particle dust removal. A large particle dust removal device is arranged at a left side of an electrostatic dust catcher main bodyand comprises a shell, the shell is of a hollow cuboid plate-shaped structure which is vertically arranged, an air inlet pipe and a connection pipe are symmetrically arranged at a left side and a right side and are horizontally arranged, a right end of the connection pipe is connected with an air inlet, a guide rail is arranged at the top of an inner cavity of the shell and is perpendicular to theair inlet pipe, a trolley is arranged at the bottom of the guide rail in a matching way, a filtering net plate is arranged at the bottom of the trolley, is of a cuboid plate-shaped structure and is arranged between the air inlet pipe and the connection pipe. The electrostatic dust catcher has the beneficial effects that the whole structure is novel; and by additionally arranging the large-particle dust removal device, large-particle substances in smoke are effectively reduced before the smoke enters the electrostatic dust catcher, and the filtering effect of the electrostatic dust catcher isensured.

Description

technical field [0001] The invention relates to the technical field of electrostatic precipitators, in particular to an electrostatic precipitator for pre-dedusting of large particles. Background technique [0002] The working principle of the electrostatic precipitator is to use a high-voltage electric field to ionize the flue gas, and the charged dust in the airflow is separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, which are called discharge electrodes. The positive electrode is made of metal plates of different geometric shapes, called the dust collecting electrode. The performance of the electrostatic precipitator is affected by three factors: the nature of the dust, the structure of the equipment, and the velocity of the flue gas. The specific resistance of dust is an index for evaluating conductivity, which has a direct impact on dust removal efficiency. If the s...

Problems solved by technology

These conditions will lead to a decrease in dust removal efficiency.

[0003] At present, the existing electrostatic precipitator lacks the dust removal treatment of large particles before the flue gas enters, resulting in low dust removal efficiency of the electrostatic precipitator, and the dust removal effect is not obvious
