Definitions

  • the invention belongs to the technical field of air pollution prevention and relates to a method for removing particulate matter in a gas, in particular to a method for removing particulate matter in a gas (air, flue gas, exhaust gas, etc.).
  • the adsorption of activated carbon can effectively remove particulate matter, but there is a problem that the adsorption material is saturated to lower its adsorption performance, and the invention effectively solves the problem that the adsorption property of the adsorbent is stable.
  • the efficiency of removing the fine particles is improved, and the use of the existing process and equipment is not substantially affected. It is not only more efficient than the existing methods, but also economical, energy-saving, easy to implement, and can effectively remove fine particles of PM2.5 level, thus reducing the pollution of the atmosphere.
  • a method for removing particulate matter in a gas comprising the steps of: adding new particulate matter to a gas that needs to be removed, adding new particulate matter in order to cause particulate matter in the gas to adhere to the added particulate matter, by filtering or other means
  • the added particulate matter is separated from the raw gas to remove the original particulate matter in the gas.
  • the particles are microspheres of the order of millimeters to micrometers.
  • the particulate material may be a polymer material, a polymer material, a composite material, a magnetic composite material, a polyethylene foam, a polypropylene, a plastic, a rubber, a resin, a glass, or a ceramic.
  • the main feature is insulation, which is easy to rub and electrify. It can be spherical or ellipsoidal or other shapes that are easy to electrify.
  • the added volume fraction of the particulate matter does not exceed 25% of the total volume of the gas.
  • the added volume fraction of the granules does not exceed 12% of the total volume of the gas. Adjust according to the concentration of particulate matter removed from the gas.
  • the gas is suitably turbulent, so that the gas flows as much as possible through the surface of the added particle ball to increase the attraction and adhesion of the particles to the gas removed.
  • the invention improves the efficiency of removing fine particles by adding charged particles in the gas, and basically does not affect the use of the existing process and equipment. It is not only more efficient than the existing methods, but also economical, energy-saving, easy to implement, and can effectively remove fine particles of PM2.5 level, thus reducing the pollution of the atmosphere.
  • the adsorption performance is stabilized by the operations of cleaning and dust removal of the particulate matter added for recycling, and the problem of maintaining the adsorption capacity in the adsorption of activated carbon is solved.
  • FIG. 1 is a schematic view showing a method of removing particulate matter in the gas of the present invention.
  • the invention adopts a method for adding charged particles to a gas (the particle size range can be several millimeters to several micrometers according to the case), and the total addition amount does not exceed 25% of the total volume after mixing, and generally recommends no more than 12%.
  • the original harmful particles in the gas are impacted or attracted to the added particulate matter, and the charged particulate matter may be added to the airflow or the gas by other means, so that the particulate matter can be formed as shown in FIG. After the particles, the particles are evenly distributed over a path or time.
  • the method can be implemented by adding in the existing flue gas treatment process, collecting and recovering after the flue gas (exhaust gas) passage runs for a certain path (or time), and adding the particulate matter to be properly cleaned, treated, and recycled. Or discard after repeated use.
  • the technical solution of the present invention can spray a polyethylene particle ball with a small density at the front end portion of the channel of the existing bag filter system.
  • the length of the self-channel before the addition of the particle ball is appropriate and insulated, so that the particle balls are sufficiently rubbed against each other.
  • An obstacle is placed in the cross section of the flue gas passage to make the flue gas passage form a turbulent state, so that the particle ball is thoroughly mixed with the flue gas, and then the particles are filtered out through the bag filter. It is also possible to eject the pellets in the flue gas passage after passing through the baghouse and then filter them out. According to the content of the particulate matter in the flue gas, multiple and multiple injections and filtration are performed.

Abstract

L'invention concerne un procédé d'élimination de particules d'un gaz. Le procédé comprend les étapes consistant: à ajouter de nouvelles particules dans le gaz pour lequel l'élimination est nécessaire, le but de l'ajout de ces nouvelles particules est de permettre à des particules dans le gaz d'être adsorber par les particules ajoutées, à séparer les particules ajoutées du gaz existant par filtration ou par d'autres moyens, mettant ainsi en œuvre l'élimination des particules existantes dans le gaz. En ajoutant des particules chargées électriquement au gaz, l'efficacité d'élimination des particules fines est augmentée.
