AI Technical Summary

Problems solved by technology

Suboptimal airflow into the filter results in uneven distribution of dust, temperature or airflow velocity, reducing filtration efficiency and resulting in suboptimal cleaning
Due to this uneven flow distribution, particle deposits are easily formed, which slowly reduces the flow cross-section in the electrostatic filter and reduces its efficiency

Embodiment Construction

[0033] figure 1 An exemplary embodiment of an electrostatic filter arrangement 1 according to the invention is shown, which has an electrostatic filter 2 , an air supply 3 and an exhaust 4 . During operation of the electrostatic filter device 1 , said air supply device 3 carries the air flow 5 to be filtered and deflects it from a vertical direction into a substantially horizontal direction and directs it towards the filter 2 . The particles contained in the air stream 5 to be filtered are then removed in the filter 2 by means of the aforementioned electrical process, and the filtered air stream 6 is then output from the electrostatic filter device 1 via the exhaust device 4 .

[0034] In this embodiment, the gas supply device 3 comprises a vertical inflow channel 7 with a substantially constant flow cross-section. A bend 9 in the inflow channel adjoins the inflow channel 7 in the direction of the main flow. Here, the direction of the airflow 5 to be filtered changes from ve...

Abstract

A vortex arrangement (11) that generates a leading edge vortex (16) is arranged in the incoming flow channel (7). A secondary vortex arrangement (12) that generates a separate leading edge vortex (17) is arranged in the gas inlet hood (8) ahead of the flow distributor (10) in the direction of gas flow. An admixture arrangement (19) is arranged near the vortex arrangements. An independent claim is also included for an electrostatic filter arrangement.

Description

technical field [0001] The invention relates to a gas supply device for an electrostatic filter and an electrostatic filter device having an electrostatic filter and a gas supply device according to the preamble of claim 1 . Background technique [0002] Electrostatic filters are used in waste incineration plants, power generation plants, or combustion production plants in industry, such as cement, lime, gypsum, iron, or steel manufacturing, to filter substances that are difficult to separate from air streams, exhaust gases, or gases in general. Solid particles, for example, fine dust particles. For this purpose, the airflow is guided through an electric field in which the electrons released by the electrodes attach to the dust particles and move together with them in the direction of the collecting electrodes, where they are separated. [0003] Therefore, the gas must flow into or through the filter as evenly as possible so that the electrostatic filter can clean the gas m...
