Equipment removing soot from e.g. open-flame light sources such as candles or kerosene lamps and disposing of it harmlessly

摘要

Rising soot is removed on catalytic or pyrolytic metal sheets (2). Preferred features: Sheets (2) are located in a chimney (1) which is e.g. hood-like, trapezoidal or rectangular in form. Sheets are employed for catalysis or pyrolysis of the soot. Resulting carbon dioxide escapes. The chimney can be shut off. The closure sheets (4) can be slid into one another, telescopically. Sliding may be achieved mechanically; a motor may be used. The catalytic sheets have channels for the rising hot air containing soot. They filter the soot and are formed for optimal filtration effect. Soot destruction is monitored by sensors. Catalytic sheets operate at lower temperatures than pyrolytic sheets, in e.g. the region 150-600 deg C. The sensor is connected with the current supply for the catalytic or pyrolytic soot removal, such that following cessation of purification, the current supply is interrupted. The chimney is mounted on a support (7), which is connected to the open flame light source support (8). Both supports are interconnected or the source support can be moved freely for central arrangement under the chimney support. The source is cooled for optimum stoichiometry during combustion of the illuminant fuel (candle wax, paraffin, etc.). Sources may have conventional cooling systems. The chimney can be closed by lamellae, under sensor or manual actuation.
