Abstract
The invention relates to extension-type gas-solid high-speed two-phase flow efficient heating equipment. The extension-type gas-solid high-speed two-phase flow efficient heating equipment comprises a heating pipe, a gas-solid mixture circulation inlet pipe, a gas-solid mixture circulation outlet pipe, a heat source pipe inlet and a dewatering pipe outlet. The gas-solid mixture circulation pipes are arranged in the heating pipe; the heat source pipe inlet is formed in the top end of the outer side of the heating pipe; the dewatering pipe outlet is formed in the tail end of the outer side of the heating pipe; outer sleeves are arranged on the outer sides of the gas-solid mixture circulation pipes; and zones between the outer sleeves and inner pipes serve as heat source circulation pipes, and steam circulates along annular sleeve channels. Rib plates circumferentially arranged at intervals are arranged on the inner side or the outer side of an original gas-solid mixture pipe. A gas-solid mixture passing through the equipment at a high speed can be rapidly heated through the equipment, and the abrasion requirement of the gas(steam)-solid mixture can be met. The problems in friction durability, heat exchange efficiency, circulation resistance, accumulated detonation and the like of the heating equipment are solved.
