Embodiment 1

[0020] Such as figure 1 , 2 As shown, the tube bundle type gas-solid high-speed two-phase flow high-efficiency heating equipment of the present invention includes: a heating pipe body 7, a gas-solid mixture circulation inlet pipeline 1, a gas-solid mixture circulation outlet pipeline 2; a heat source pipeline inlet 3, and a drain pipeline outlet 4 , Rib plate 5. Among them, a gas-solid mixture circulation pipe 1 is provided in the heating pipe body 7; a heat source pipe inlet 3 is provided at the outer top of the heating pipe body 7; a drain pipe outlet 4 is provided at the outer end of the heating pipe body 6. An outer sleeve 8 is arranged outside the gas-solid mixture pipeline; the area between the outer sleeve 8 and the inner tube 9 is used as the heat source circulation pipeline 6, and the steam circulates along the annular passage of the sleeve. Ribs 5 arranged at circumferential intervals are arranged on the inside or outside of the original gas-solid mixture pipeline....

specific Embodiment approach

[0022] The specific embodiment that heater of the present invention is used for gas-solid mixture heating is:

[0023] The gas-solid mixture enters the gas-solid mixture channel provided with the rib plate 5 from the gas-solid mixture circulation inlet pipe 1; at the same time, the heat source enters the heating pipe body 7 through the heat source pipe inlet 3; the heat source circulates along the heat source circulation pipe 6 casings, and The gas-solid mixture undergoes countercurrent heat exchange; after the temperature of the gas-solid mixture increases, it enters other connecting pipes through the outlet pipe 2 of the gas-solid mixture, and the heat source that completes the heat exchange releases heat to form water (or steam, air), and then exits through the water pipe 4 collected for other use.

[0024] The heater of the present invention can be applied in any heat exchange environment with different media. For example: gas-solid mixture heating device for coal-fired p...

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.

Description

technical field [0001] The invention relates to a heating device, in particular to a casing type high-speed gas-solid two-phase flow high-efficiency heating device. Background technique [0002] In various industrial processes, heaters are mostly used to heat liquids or gases using high-temperature steam sources (or gas sources). With the rapid development of industrial technology, it is urgent to solve the heating problem of high-speed flowing gas-solid mixture. At present, there are many technical problems in the heating of high-speed flowing gas-solid mixture particles, such as easy wear, low heat transfer efficiency, large flow resistance, and accumulation deflagration, which have not been ideally solved so far. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a casing type gas-solid high-speed two-phase flow high-efficiency heating equipment, which can effectively improve heat exchang...
