Embodiment Construction
[0028] The dust pretreatment method to improve the efficiency of the dust collector is that the dust is charged with positive and negative charges by the charging area in the inlet flue of the electrostatic precipitator, and is forced to mix in the forced mixing area, so that the fine particles and coarse particles are attracted and adhered to become Large particles can improve the dust removal efficiency of the dust collector.
[0029] Such as figure 1 , 2 As shown, the dust pretreatment device for improving the efficiency of the dust collector has a housing 4. There are charging areas and forced mixing areas in the front and rear of the housing, and multiple groups of positive electrodes 1, negative electrodes 2, and grounding electrodes are arranged in parallel in the charging area. 3. An intercepting body 5 is provided in the forced mixing area. The positive pole 1 and the negative pole 2 are connected to a high-voltage power supply, and the high-voltage power supply is ...

The invention discloses a dust pretreatment method and a device for improving the efficiency of a dust collector. The method of the invention includes that the dust in a flue of the inlet of an electric dust collector is charged with positive electricity and negative electricity by a charging area and mandatorily mixed in a mandatory mixing area to ensure that fine particles and coarse particles are attracted and attached with each other to form large particles, thus improving the dust collection efficiency of the dust collector. The device of the invention is provided with a shell body which is provided with the charging area and the mandatory mixing area in the front and at the back respectively; a plurality of positive electrodes, negative electrodes and earth electrodes arrayed in sequence are arranged in the charging area in parallel while an interception body is arranged in the mandatory mixing area. The device of the invention has simple structure, smaller volume, obvious effects and low manufacturing cost and can be directly installed in the flue with short installation time and little influence on production and used for the processing in factories and the on-spot installation by hoisting. The dust pretreatment method and the device of the invention can be applied to the front end of various dust collectors such as a cyclone dust collector, a wet dust collector, an electrostatic dust collector, a bag dust collector, and the like, so as to effectively improve the dust collection efficiency of the dust collectors.
Description
technical field [0001] The invention relates to environmental protection technology, in particular to a dust pretreatment method and a device thereof for improving the efficiency of a dust collector. Background technique [0002] At present, with the development of my country's economy, more and more dust collectors are used in the control of dust emissions in various industries such as electric power, thermal power, building materials, cement, chemical fertilizers, and metallurgy. Especially in recent decades, my country has strengthened independent research and development while absorbing foreign technology. Now dust collectors have become one of the industries with relatively strong technical force, high equipment level and strong development ability in my country's environmental protection industry. Dust collectors mainly include cyclone dust collector, wet dust collector, bag filter and electrostatic precipitator, etc. The main principles are briefly described below. ...
