Module-type waste heat vapor generator

Abstract

The invention relates to the technical field of waste heat recovery, in particular to a module-type waste heat vapor generator. The module-type waste heat vapor generator comprises a heat transfer basic module and a steam separator (7), wherein a steam outlet of the upper end of the heat transfer basic module is connected with an inlet of the steam separator (7) through a steam guiding pipe (10). A first outlet of the upper end of the steam separator (7) is connected with a steam discharge pipe (6). A second outlet of the lower end of the steam separator (7) is connected with a water drain pipe (9). The water drain pipe (9) is connected with a water collecting pipe (12) at the lower end of the heat transfer basic module to form a circulation loop. The module-type waste heat vapor generator is novel and simple in structure, the heat transfer basic module can be designed according to the size of quantity of smoke, steam and the number of the heat transfer basic module is decided according to the size of thermal power, and the problems that design, manufacture and use of the waste heat recovery are cockamamie are solved. Work efficiency of design, manufacture and management is improved, safety of thermal power and water circulation is guaranteed, and reliability of steam-water separation is guaranteed, and the module-type waste heat vapor generator is convenient to manufacture, assemble and operate, reliable in circulation, and easy to control.

Description

[technical field] [0001] The invention relates to the technical field of waste heat recovery, in particular to a modular waste heat steam generator. [Background technique] [0002] At present, many waste heat recovery projects in my country basically use hot flue gas to heat water to generate steam (or hot water). In each recovery project, there is a flue gas volume and the thermal power is determined according to the flue gas temperature. However, the flue gas volume and flue gas temperature of each project are different. When designing waste heat recovery projects, the structural size of the heat exchanger needs to be determined according to the flue gas volume, and the heat exchange area should be determined according to the thermal power. Such projects are in high demand, and the design, manufacture and management work is cumbersome. [Content of the invention] [0003] The purpose of the present invention is to solve the above-mentioned shortcomings and provide a modu...
