Still kettle quick accumulated residual steam accumulated energy circulating device and method

Abstract

The invention discloses a still kettle quick accumulated residual steam accumulated energy circulating device and a still kettle quick accumulated residual steam accumulated energy circulating method. The device comprises an energy accumulating device communicated with a still kettle, wherein the energy accumulating device at least comprises a first energy accumulating container and a second energy accumulating container; steam inlet ends of the first energy accumulating container and the second energy accumulating container are communicated with a steam discharging end of the still kettle through a steam discharging pipeline; steam discharging ends of the first energy accumulating container and the second energy accumulating container are communicated with a steam inlet end of the still kettle through a steam returning pipeline; a steam discharging control valve used for controlling medium flow in the steam discharging pipeline is arranged on the steam discharging pipeline; a steam returning valve used for controlling medium flow in the steam returning pipeline is arranged on the steam returning pipeline. The still kettle quick accumulated residual steam accumulated energy circulating device is an energy accumulating device which takes water (or soft water) as a medium. The principle is that residual steam in a steam discharging still kettle is stored by adopting a high pressure-dividing way to a low pressure-dividing way, and in a boosting process of a steam inlet still kettle, the stored steam is released from the low pressure-dividing way to the high pressure-dividing way to be supplied.

Description

technical field [0001] The invention relates to the technical field of autoclave equipment, in particular to an autoclave rapid accumulation type residual vapor energy storage circulation device and method. Background technique [0002] Still kettle claims steam-cured kettle again, is a kind of bulky, large pressurized vessel that weight is heavier. The autoclave has a wide range of uses, and is widely used in aerated concrete blocks, concrete pipe piles, lime sand bricks, fly ash bricks, microporous calcium silicate boards, new lightweight wall materials, thermal insulation asbestos boards, high For the autoclave curing of building materials such as strength gypsum, the hydrothermal reaction of Cao—SiO2—H2O is completed in the kettle. [0003] During use, steam needs to be generated in the autoclave, but the existing steam in the autoclave is directly discharged, which causes a waste of heat resources, and secondly, the discharged steam has a large amount of heat, which is...

Problems solved by technology

[0003] During use, steam needs to be generated in the autoclave, but the existing steam in the autoclave is directly discharged. First, it causes waste of heat resources, and second, the discharged steam has a large amount of heat. In addition, due to the large volume of the autoclave, when boosting the pressure of the autoclave, one autoclave performs a steam dump mode on the other autoclave to boost the pressure. In this way, one It is during the pressure-lifting process of the autoclave that the temperature difference is large, which affects the quality of the green body in the autoclave
