Pressure vessel convenient processing method and device for multi-state hybrid material

Abstract

The invention discloses a pressure vessel convenient processing method and device for multi-state hybrid materials; a normal pressure vessel tank is provided with a feeding valve, a blow valve and accessories of specific structures, thus forming a novel pressure vessel system; the novel system is controlled by a well-designed program, thus preventing the problems that existing valves are not suitable for processing hybrid materials; the whole device is simple and practical in structure, employs pressure balance, reciprocating open / close, free fitting and gradient pressure reduction rules, and considers gas, solid and liquid substance state characteristics; the novel method and device can process biomass solid state material with high efficiency and quality under high temperature high pressure bad conditions; the method and device are high in production efficiency, wide in application scope, good in sealing performance, low in invest cost, less in safety faults, and can be widely applied to various intermittent bearing tanks, thus providing relative ideal equipment for industrial applications.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to technical equipment and a control method for pressure vessels to conveniently process biomass materials. Background technique [0002] In industrial production, pressure vessels are widely used for high-temperature and high-pressure treatment of various materials, and the effect is obvious, but the valves that are matched with it are relatively lagging behind, and most of them are designed for a single liquid or solid or gaseous material in the early stage. control structure. With the emergence of new materials and new industries, the demand for new valves is becoming stronger and stronger, so it is very important and urgent to develop special equipment suitable for multi-state mixed materials. [0003] Biomass materials inevitably contain impurities such as sand and soil. When processed in a pressure vessel, steam (or other pressurized gas), liquid water (or other ...

Problems solved by technology

[0004] For example, some pneumatic or electric ball valves have better agility and tightness, but they are fundamentally derived from liquid material valves. Under severe working conditions, they are prone to plugging and leakage due to frequent replacement, and are limited by the structure. less, the scope of application is relatively narrow

[0005] Another example is the "quick opening" device that is used more often. Although it can adapt to the characteristics of solid materials, it is bulky and heavy. It needs motors and mechanical transmission to realize opening and closing. The single time is long and energy consumption is large, which directly affects production efficiency.

[0006] Another example is the design of solid material valves provided by some universities and scientific research institutes. Most of them are not suitable for production practice. They are vulnerable to damage and require a lot of maintenance. They belong to the laboratory stage and are difficult to see industrial application.
