Abstract
A smoke removal apparatus, capable of operating in a confined space without ventilation of the apparatus to the atmosphere to provide removal of smoke from air to be treated. The apparatus includes one or more of the following filters: a mechanical filter; an electrostatic filter; and/or a chemical filter. The apparatus is arranged to collect smoke from a relatively higher position, pass smoke through the one or more filters/and expel treated air to a relatively lower position.
Claims41
A smoke removal apparatus, for the removal of smoke from air to be treated in a confined space and capable of operating in the confined space without ventilation of the apparatus to the atmosphere, comprising one or more of the following filters:
- a mechanical filter;
- an electrostatic filter;
- and
- a chemical filter;
- wherein the apparatus is arranged to collect smoke from a relatively higher position, pass smoke through the one or more filters, and expel treated air to a relatively lower position, and
- the apparatus is provided with an outlet arranged in a substantially lower region of said apparatus to achieve radial distribution of treated air so as to provide a layer of treated air beneath the smoke, and substantially horizontal to the ground, to clear the space of smoke, said apparatus further comprising a centrifugal fan positioned at said outlet, said fan having a plurality of fins for achieving said radial distribution of said treated air.
A method of smoke removal comprising,
- providing a smoke removal apparatus, capable of removing smoke from air to be treated in a confined space, and capable of operating in the confined space without ventilation of the apparatus to the atmosphere, comprising one or more filters selected from a mechanical filter;
- an electrostatic filter;
- and a chemical filter, and
- collecting smoke from a relatively higher position, passing smoke through the one or more filters, and expelling treated air to a relatively lower position, through an outlet arranged in a substantially lower-region of the apparatus, wherein
- the air is expelled so as to result in a radial distribution of treated air providing a layer of treated air beneath the smoke, and substantially horizontal to the ground, to clear the space of smoke, said apparatus comprising a centrifugal fan positioned at said outlet, said fan having a plurality of fins for achieving said radial distribution of said treated air.
