Embodiment Construction

[0019] Such as figure 1 The wet electrostatic precipitator for waste gas treatment shown has acid and alkali corrosion-resistant metal discharge electrodes, dust collection electrodes, high-voltage discharge circuits, waste gas main pipes, purified gas outlets, and dust collection chambers; it also has waste gas branches, which pass through The control valve is connected to the side wall of the exhaust gas main pipe, part of the metal discharge electrode is sleeved in the exhaust gas branch circuit, and its discharge end is exposed outside the exhaust gas branch circuit.

[0020] A sensor capable of measuring the pH value of the exhaust gas is installed on the exhaust gas main pipe, the sensor is connected to the controller through the signal line, and the controller is connected to the control valve through the control line; when the pH value of the exhaust gas in the exhaust gas main pipe is small or the pH value is large , the control valve opens.

[0021] The exhaust gas ...

Abstract

The invention provides a wet-type electrostatic precipitator for waste gas treatment. The wet-type electrostatic precipitator comprises an acid-resistant and alkali-corrosion-resistant metal dischargeelectrode, a dust collection electrode, a high-voltage discharge circuit, a waste gas main pipe, a waste gas branch, a purified gas outlet and a dust collection cavity, wherein the waste gas branch is connected to the side wall of the waste gas main pipe through a control valve, and part of the metal discharge electrode is sleeved in the waste gas branch. According to the wet-type electrostatic precipitator, acidic and alkaline waste gas, water vapor and dust can be removed, and the discharge electrode is not prone to be oxidized or bonded with oil stain to lose the discharge function.

Description

technical field [0001] The invention belongs to waste gas treatment technology. Background technique [0002] Wet electrostatic precipitator is a high-voltage electrostatic precipitator used to treat wet gas. It is mainly used to remove dust, acid mist, water droplets, aerosol, odor, PM2.5 and other harmful substances in wet gas. Ideal equipment for atmospheric dust pollution. The wet electrostatic precipitator is usually referred to as WESP. The basic principle of dust removal is the same as that of the dry electrostatic precipitator. It has to go through three stages of charging, collecting and cleaning. [0003] The wet electrostatic precipitator has a high-voltage discharger and a discharge electrode, and another dust collection electrode. The discharge electrode is generally a metal tip; the dust collection electrode can be a conductive material or a non-metallic material (a conductive water film is formed by water flow). [0004] In the process of producing glyphosat...
