Novel on-line hydrogen-removal long-acting row-type tube bundle steel-water heat tube air preheater

The invention relates to a novel on-line hydrogen-removal long-acting row-type tube bundle steel-a water heat tube air preheater. In the invention, all single heat tubes are connected and set to be a row-type heat tube; at least two rows of heat tubes are set to be a group of tube bundle; and the preheater comprises a group or at least two groups of tube bundles I and tube bundles II. The tube bundles are arranged in a sealing box body and every row of heat tubes are provided with a gas collecting chamber and a mesh medicament frame; the gas collecting chamber of every group of tube bundles is arranged outside the box body which is provided with a high-temperature fluid inlet and outlet and a low-temperature fluid inlet and outlet. The upper parts of every row of heat tubes are connected together by a gas collecting tube and the lower parts thereof are connected together by a liquid collecting tube; and every sealing tube is internally filed with working medium for transferring heat quantity.
