The invention provides a containment built-in efficient
heat exchanger adopting double-wheel double-blade
hybrid power air suction, which mainly comprises a
heat exchanger inlet header, a heat exchange tube, a
heat exchanger outlet header, a self-flowing type air-
breathing system and a
cutting type air-
breathing system. The self-flowing type air suction
system comprises a water conveying structure, a water bucket type
water wheel, an air suction structure, an
exhaust pipe and a gear steering box. The
cutting type air suction system comprises a water conveying structure, a
jet flow structure, an air suction structure, a drainage
pipe and an
exhaust pipe. The two air suction systems are arranged on the upper portion and the lower portion respectively to form a
hybrid power air suction system,
potential energy of
water flow generated by
steam condensation can be converted into
jet flow kinetic energy, an air suction structure is driven to rotate, and
suction force is generated, so that a non-condensable gas film near a heat exchange
pipe is sucked away, and steam is made to condense and exchange heat on the outer surface of the heat exchange
pipe better. When a
crevasse accident occurs in the containment, heat in the containment can be efficiently taken away, contact between steam and a pipe bundle is enhanced, and efficient
heat transfer is achieved.
