Problems solved by technology
However, this heating method requires that the gas must be a high-speed compressed gas. Due to this limitation, its application range is relatively limited.
[0006] In addition, in the traditional direct heat exchange heat exchanger, the outlet temperature of the heated gas leaving the heat exchanger is difficult to be accurately controlled

The invention discloses a gas heat exchanger and a gas heat exchange system with the gas heat exchanger. The gas heat exchanger comprises a heat exchanger body, a separating part and heat carriers, wherein the separating part is arranged in the heat exchanger body in the direction of the central axis and separates the heat exchanger body into at least one pair of containing parts, the containing parts in each pair are arranged oppositely relative to the central axis in the radial direction, and the heat carriers are contained in the containing parts. The heat carriers are made of nonmetal solid materials and have small-ball-shaped, or flaky or porous structures. The gas heat exchanger absorbs sensible heat and latent heat of heat supply fluid to the maximum for heating gas, improves heating efficiency, reduces heat loss, lowers cost and avoids risks of hazardous reactions or contamination caused by contact between the heat supply fluid and gas to be heated, so that safety is improved, and the gas heat exchanger is simple and reliable in structure and convenient to operate.
Description
technical field [0001] The invention relates to the field of heat exchange, in particular to a gas heat exchanger and a gas heat exchange system having the same. Background technique [0002] Gas heating devices are widely used in domestic, metallurgy, chemical and other industrial applications, such as cooking and room heating, etc., and are used in many appliances (such as hair dryers and clothes dryers, etc.). The blast furnace hot blast stove, one of the main supporting equipment for blast furnace ironmaking in the metallurgical industry, continuously provides high-temperature hot air above 1000°C for the blast furnace. The tubular gas heating furnace widely used in the chemical industry provides high-temperature air (650-800°C) for the production of catalysts. Existing devices for heating gas are mainly divided into three types: electric heating, gas heating and high-speed gas pneumatic heating. [0003] Electric heating generally uses electric heating wire, electric ...
