Description

Technical Field

[0001] The utility model belongs to the technical field of air heaters, and in particular relates to a filtering air heater. Background Art

[0002] The heater is a combined unit composed of a ventilator, a motor and a radiator. It is suitable for various types of workshops where air recirculation is allowed. When the air does not contain dust or flammable gases, it can be used for circulating air heating. The heater is mainly composed of an air heater and a fan. The air heater dissipates heat, and then the fan sends it out to adjust the indoor air temperature. The air heater is composed of spiral finned tubes. For example, the heat dissipation exhaust pipe of the steam type heater is wound on a seamless boiler tube with a wall thickness of Φ21.5 with a special aluminum strip equipment. The sheet spacing is 2.5mm. The exhaust pipe and the heat medium circulation pipeline are integrally welded structures. The working pressure of the heater is below 0.8MPa. The heating principle of the heater is mainly realized by the fluidity and temperature difference effect of hot air. When the heater is working, the motor drives the fan impeller to rotate, sucking hot air from the air inlet. After being heated by the electric heating element, the hot air is blown from the air outlet to the room through the rotation of the deflector and the fan impeller.

[0003] Existing heaters directly heat the indoor circulating air when in use, do not replenish fresh air (outdoor air), and cannot purify the air. Therefore, long-term use will cause indoor air turbidity and reduce indoor air quality. In addition, it is not convenient to clean impurities after air filtration, which affects the subsequent filtration effect of the heater, may cause blockage, and reduce the service life of the heater.
