“…As the thickness of the deposited PM layer on the collecting electrodes increases, the deposition efficiency decreases and can lead to a back corona in case of emergency. A rotating brush is not a suitable option in this case [32], as the stress on the chimney system in case of impact would have to be considered in the design of the rapping device. The focus is thus on the development of devices that are effective with low stress on the design of the precipitator and the chimney system, not least in terms of operation.…”

Capturing particulate matter (PM) is an important issue due to the protection of human health and the quality of their life. This paper describes the innovation of an affordable particulate matter capture device for small heat sources to reduce particulate matter emissions. The design of two investigated variants of the device is based on the principle of a tubular electrostatic precipitator with one charging electrode placed in the chimney. The design of the precipitators is aimed at increasing the area of the collecting electrodes by elements dividing precipitation space, with a simultaneously increased number of charging electrodes. The influence of the elements’ application on the pressure drop and the gas flow velocity through the devices is analyzed by computational fluid dynamics (CFD). The work is further focused on the economic evaluation of precipitators and design adjustments for lower energy consumption. The achieved results show the right direction of efforts to improve the equipment designed to capture PM emissions.

Thermal pyrolysis of city life garbage gas is an effective means to achieve waste reduction, harmless treatment and resource utilization. However, the particles in the fuel gas has a detrimental effect on its recycling. It must be purified before recycling. The waste gasification gas purification process by using wet electrostatic precipitator and its feasibility are presented in the paper. The characteristics of waste gasification gas corona discharge are studied under the condition of changing gas pressure, polar matching type and electric field gas speed. Experiment on collection of the dust from a garbage power plant was carried out in a wet electrostatic precipitator. The results show that: waste gasification gas can form a steady corona current in the electrostatic precipitator, and the corona discharge current decreases with the gas pressure. In the main gas components, the increase of CO content is beneficial to the gas corona discharge while the CO2 is opposite. The corona discharge performance is the best when the polar distance is 300mm and the polar matching type is the RS four tooth awn barbed wire to 480C type plate. For the above types of wet electrostatic precipitator, when the water spraying pressure is 0.4 MPa, the electric field gas speed is 1.1 m/s, the collection efficiency of the particles in waste gasification gas will be up to 97.5%. For the municipal solid waste pyrolysis gas which CO component is more than 20%, the wet electrostatic precipitator can be used for purifying its particles effectively.
