摘要： The subject of the invention is a procedure, a filter module, and an air cleaning device composed of such filter modules for the highly efficient cleaning of air containing small contaminating particles. In the course of the procedure, the principle of adhesion and repelling effect is exploited to capture the contaminating particles in the device composed of an appropriate number of filter modules (1). The air to be cleaned is moved like a quasi-electrodynamic linear engine in the device, so that the mass and/or size of the coagulated particles is increased by the powers of two as necessary while passing through two sequential filter modules (1), up to 220 value. This way, the flow velocity of the fine grains with increased mass is decreasing gradually and they are separated or fall out from the flow space, meaning that particles with a starting size below 1 micrometre, in the nano-range, which are the most harmful to the human body, may also be captured. The essential part of the invention is the filter module (1) that is fitted with electrodes (7), composed of a collector (5) and a separator (6) located at a given distance, which are connected to a positive or negative high voltage (8, 9) and are surrounded by a cover consisting of a base plate, connected to zero potential (10), side plates, and a cover plate. Two electrodes (7) form an electrode pair, and two electrode pairs form a filter module (1), where the electrode pairs are placed so that there is one electrode (7) of the opposite potential installed between two electrodes (7) of the same potential. The solution according to the invention may be used in versatile ways, especially on the field of civil environmental protection, as stand-alone, pre-, or post-filter, such as for cleaning the air and exhaust gas in the chimney of industrial plants, for cleaning polluted urban air, for cleaning, de-germination, and filtering pollen from the air of closed premises, and for military purposes on the field of NBC safety as a pre-filter.

摘要： A cleaning apparatus may include a flow source such as a fan which creates air flow through a ventilation duct or other structure to be cleaned. A projectile source projects projectiles such as dry ice pellets proximate the structure to dislodge debris particles therefrom and introduce the dislodged debris particles into the air flow. An electrostatic precipitator removes the particles from the air flow. An upstream sensor may be used to detect the particles upstream of the electrostatic precipitator and determine if the structure is clean using a controller. A downstream sensor may be used to detect the particles downstream of the electrostatic precipitator and determine the efficiency of the electrostatic precipitator using the controller. Carbon dioxide within the air flow may also be detected.

摘要： Disclosed is an electrostatic aerosol concentrator for the concentration of aerosol particles and their collection for subsequent analysis. The concentrator comprises an airflow chamber that includes alternately energized and grounded electrode elements that work in concert to impart radial inward motion to charged aerosol particles and focusing them toward an enriched aerosol outlet. If desired, filtered air inlets may be used to provide a sheath of aerosol-free air along the chamber periphery and prevent deposition of particles onto electrode surfaces. Aerosol particles entering the airflow chamber may carry a positive or negative charge naturally, or a charge may be induced on the particles using a charging section located upstream of the aerosol inlet. Natural or induced charges on the aerosol particles may be used to selectively concentrate subpopulations of aerosol particles from a mixture of particles. For example, bacterial spores or aerosolized viruses may be selectively enriched without concentrating other aerosol particles. The particles of interest are focused and collected at an aerosol rich outlet in a small air volume, while the majority of the airflow, stripped of particles of interest, is purged to the atmosphere through an aerosol lean outlet.
