The radiator module comprises an emitter unit, a radiation source (2) co-axially arranged into a quartz glass envelope tube (3), and a protective gas pressure unit. The emitter unit comprises a head part, which is connected to quartz glass cladding tube and through which a protective gas inlet unit (6') into a space between the envelope tube and the radiation source is inserted. The protective gas pressure unit provides a protective atmosphere through the protective gas inlet unit in the space between the quartz glass envelope tube and the radiation source. The radiator module comprises an emitter unit, a radiation source (2) co-axially arranged into a quartz glass envelope tube (3), and a protective gas pressure unit. The emitter unit comprises a head part, which is connected to the quartz glass envelope tube and through which a protective gas inlet unit (6') into a space between the envelope tube and the radiation source is inserted. The protective gas pressure unit provides a protective atmosphere through the protective gas inlet unit in the space between the quartz glass envelope tube and the radiation source having an excess pressure relative to the ambient pressure of 0.8 mbar. A capillary tube between the tube and the radiation source extends from the protective gas pressure unit to an opposite end of the tube. An outlet for the protective gas is provided in the space between the tube and the radiation source. A protective gas outlet unit is provided in the head part. The protective gas pressure unit comprises a protective gas supply line connected to an introduction unit and a protective gas discharge line connected to the outlet unit, in which a pressure measuring device is provided, which is connected to a control unit arranged in a protective gas supply solenoid valve such as controllable proportion valve. The protective gas outlet device of the emitter units is connected with the protective gas outlet in parallel or in series. The control unit is coupled to the radiation source using a power reducing ballast for switching off the radiation source when pressure is below the minimum excess pressure of 0.8 mbar and above a pre-determined maximum pressure detected by a pressure gauge. The head part is connected to the tube using an annular flange. The annular flange is formed with a tapered inner surface, which corresponds to a conical open end of the tube, and peripheral grooves for receiving sealing rings are provided on the inner surface of the annular flange. The annular flange is configured for fixing the radiator unit in or at an exhaust, exhaust or air cleaning device. The head part has a shape of cup and has an outwardly pointing collar, and rests against the tube. The quartz glass tube (3) is a cladding tube made of synthetic quartz glass, and has a wall thickness of 3 mm. An independent claim is included for an exhaust air, exhaust gas or air purification device. |
