Discharging devices for pressurized vessels and steam cooking systems

Abstract

The invention relates to the field of pretreatment of fiber-containing biomass materials, and discloses a discharge device for a pressure vessel and a steam cooking system. The discharge device includes a steam explosion feed buffer bin, and the steam explosion feed The upper end of the buffer bin is provided with a feed port, and the lower end of the steam explosion feed buffer bin is provided with a discharge port, and the feed port of the steam explosion feed buffer bin communicates with the discharge port of the pressurized container, For buffering and storing the discharge material of the pressure vessel, the steam explosion feed buffer bin is defined with a dilute phase zone, a dense phase zone and a discharge zone from top to bottom, wherein: the discharge zone A first steam distribution pipe is arranged inside, and the first steam distribution pipe is arranged close to the dense phase area and can distribute steam to the dense phase area to loosen the material in the dense phase area; and / or the discharge A second steam distribution pipe is provided in the area, and the second steam distribution pipe can distribute steam to the discharge port of the steam explosion feed buffer bin to facilitate the discharge of materials.

Description

technical field [0001] The invention relates to the field of pretreatment of fiber-containing biomass materials, in particular to a discharge device for a pressure vessel and a steam cooking system containing the discharge device. Background technique [0002] The continuous growth of energy demand for the development of the world economy and the increasingly severe environmental problems force people to seek renewable energy. Biomass, as the only renewable resource that can be converted into liquid fuel, is receiving increasing attention. Among the technologies for producing liquid fuels from biomass, the technology of producing fuel ethanol from biomass has attracted much attention. The production of existing industrialized fuel ethanol all uses sugar or grain as raw material, but because the output is limited by the raw material, it is difficult to meet the energy demand for a long time. Therefore, in the long run, the production of fuel ethanol from cellulose-containing...

Problems solved by technology

[0004] However, in the above, when the discharge valve is opened, a large amount of steam will enter the cyclone separator in the next process through the discharge valve and will be lost from the top of the cyclone separator, and the pressure in the digester will drop instantly, which needs to be replenished. Enter steam to maintain the pressure required for cooking, resulting in greatly reduced cooking efficiency and waste of energy
