Embodiment 1

[0034] Embodiment 1 of the present application provides a double-layer structure hydrothermal flash device, such as figure 1 As shown, it includes an upper flash tank body 1, a lower flash tank body 2, a stainless steel interlayer 3, a base 22, an insulation layer 18, and the like. The double-layer structure hydrothermal flash evaporation device is generally cylindrical, and the top cover and the bottom cover are hemispherical, and are supported by the base 22 . An insulating layer 18 is provided outside the double-layer structure hydrothermal flash evaporation device to reduce heat dissipation and increase the amount of steam generated during the flash evaporation process. The stainless steel interlayer 3 is arranged between the upper flash tank body 1 and the lower flash tank body 2 for isolating materials. The wall thickness of the stainless steel interlayer 3 adopts more than 8mm, and a stainless steel interlayer support 16 is provided on the inner wall between the upper ...

Embodiment 2

[0042] Embodiment 2 of the present application provides a working method of a double-layer structure hydrothermal flash evaporation device, including the following steps:

[0043] S1. When the high-temperature and high-pressure material after hydroheating passes through the feed pipe 4 under the control of the feed control valve 5, it enters the bottom of the upper flash tank body 1 through the upper material feed guide tube 12, and is discharged in the upper flash tank. Instantaneous release of pressure in body 1 occurs the first flash. After the material enters the bottom of the upper flash tank 1, during the flashing process, through the release of pressure, the material and water vapor move along the deflector 14 to the wall of the upper flash tank 1 and circulate from the top Backflow, the high-temperature material finally accumulates on the stainless steel interlayer 3, and the water vapor rises along the inner wall of the upper flash tank 1 through the deflector 14, and...

Abstract

The invention relates to a double-layer hydrothermal flash evaporation device which comprises an upper-layer flash evaporation tank body, a lower-layer flash evaporation tank body and a stainless steel interlayer. A feeding pipe and an upper-layer steam discharge pipe are arranged on a hemispherical top cover at the top of the upper-layer flash tank body, a feeding control valve is arranged on the feeding pipe, and an upper-layer steam discharge control valve is arranged on the upper-layer steam discharge pipe. An upper-layer material feeding flow guide pipe is arranged in the upper-layer flash tank body. A lower-layer steam discharge pipe is arranged at the top of the lower-layer flash tank body, and a lower-layer steam discharge control valve is arranged on a lower-layer steam discharge pipe. The stainless steel interlayer is arranged between the upper-layer flash tank body and the lower-layer flash tank body. Compared with the prior art, the device has the beneficial effects that through the double-layer hydrothermal flash evaporation structure, high-temperature and high-pressure materials subjected to hydrothermal treatment can be subjected to two-time flash evaporation, and compared with a common flash evaporation tank, through two times of blasting, the flash evaporation efficiency is greatly improved, the conversion efficiency of refractory organic matter is further improved, and the conversion efficiency and the generation amount of water vapor are increased.

Description

technical field [0001] The invention relates to a double-layer structure hydrothermal flash evaporation device and method, belonging to the technical field of environmental protection energy. Background technique [0002] Hydrothermal technology refers to the conversion of refractory substances under high temperature and high pressure conditions in a closed reactor. This technology has a good application prospect in the treatment of organic waste, including improving the utilization efficiency of organic matter in anaerobic fermentation and improving gas production. efficiency, improve the solid-liquid separation efficiency of organic waste, etc. In the hydrothermal system, the flash device plays a vital role in the conversion of refractory substances. Flash evaporation refers to the phenomenon that after the high-pressure saturated liquid enters the lower-pressure container, due to the sudden drop in pressure, the high-pressure saturated liquid is converted into saturated ...
