Abstract

Waste gas filtering using porous materials: organic (e.g. cellulose pulp from paper production) or inorganic (e.g. mineral wool waste) with water glass (Na2SiO3, nH2O) impregnation. According to the invention, this process binds pollution in the filter material and absorb carbon oxide in the hardening process. Plates, tube linings, bicurved planes, granulates or the like can be made of the filter material.

Description

TITLE: Waste gas filtering absorbing carbon dioxide
DESCRIPTION
Area of use
The invention concerns waste gas filtering with water glass and products made of the filter materials in continuation of or in immediate connection with the filtering process.
Technique
One way of achieving the desired function is described:
In Fig. 1 is seen that waste gas from chimney extraction is cooled followed by compression. In the next process the (porous) dilter material is impregnated / saturated with carbon dioxide. This may be done with or without vacuum. In the same or in a following process the filter material is impregnated with water glass (Na2SiO3, nH2O) in some state or other. When the desired degree of saturation has been achieved - and before hardening has taken place - the filter material is pressed or extruded into desired forms, such as tubes, plates granulates etc.
What is specialty achieved
Waste gas contains fly ash, among other things, and carbon from PNC recycling contains lead oxides which together with the carbon dioxide emission are undesirable. According to the invention all these substances are bound in the filter material.
The products derived from this process are noninflammable - also when cellulose is used as filter maerial - as they are saturated with both carbon dioxide and water glass (Νa2SiO3, nH2O) and thus are fully hardened. A great variation in porosity can also be achiebed through this process until cappillary breaking as well as low bulk density (< 1.0).

Claims

1. Waste gas filtering according to the invention characterized in that the waste gas is passed through or around a filter material (porous) which is saturated with water glass (Na2SiO3, nH2O).
2. Pellets/granulate according to claim 1 characterized in that extruded mineral wool is prepared with Na2SiO3, nH2O).
3. Plate material according to claim 1 characterized in that the filter material is cellulose pulp as made for paper production.
4. Waste gas filter according to claim 1 characterized in that the porous material is carbon.
5. Waste gas filtering according to any of claims 1-4 characterized in that both carbon oxide and pollution in the smoke as well as in the filter material (lead oxides) are bound permanently in the filter in the products made hereof.
6. Mouldable material according to any of claims 15 characterized in that it at a later addition of other substances
1) can be made fluent (bulk density < 1.0)), e.g. with urethane or "mikrosferer"??
2) can be used as a mortar product, e.g. with synthetic granite, filler or the like.

Fig. 2 shows photos of different samples:
1) Mineral wool granulates/pellets (according to claim 2) which have been extruded with Νa2SiO3, nH2O added in a well defined quantity.
2) Slice of fine granulate of mineral wool waste impregnated with Na2SiO3, nH2O.
3) Piece of cellulose plate from paper production according to claim 3. This sample has just been immersed into Na2SiO3, nH2O - and not filtered according to claim 1.
4) As 3) and exposed to 1400-1600oC for about 2 min.
5) Sheet of lead showing that Na2SiO3, nH2O binds to lead oxide which will thus be encapsulated when using carbon from PNC breakdown as filter material according to claim 4.
