Feeding valve for steam explosion operation and action mode of feeding valve

Abstract

The invention discloses a feeding valve for steam explosion operation and an action mode of the feeding valve. The feeding valve comprises a main body structure formed by an upper air cylinder part, alower valve body part and four middle support columns, and the feeding valve is assembled to the feeding inlet of a steam explosion tank. The feeding valve has the advantages that the features of gas, solid and liquid substances are considered by a conical plug type opening and closing mechanism, a free body structure and a pressure balance mode, fast feeding and sealing control of solid biomassmaterials can be achieved, the efficiency of the steam explosion operation is increased evidently, and the feeding valve is wide in application range, good in sealing performance, fast and stable in operation, simple and practical in maintenance, long in service life, widely applicable to various intermittent type pressure-bearing tanks and capable of providing ideal equipment for industrial application.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a feed valve for steam explosion operation and its function mode. 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 continuous emergence of new materials and new industries, the demand for the control of three-state mixed materials is becoming stronger and stronger. Therefore, it is very important and urgent to develop special control valves suitable for multi-state mixed materials. [0003] The use of agricultural and forestry residues and wastes such as straw and fruit shells as raw materials for industrial production is becoming more ...

Problems solved by technology

[0004] For example, commonly used electric ball valves, globe valves, plunger valves, etc., although they have good flexibility and tightness, they are fundamentally derived from liquid material valves. Under severe working conditions, they are prone to plugging and leakage due to frequent replacement. And limited by the structure, the diameter is small, the flow rate per unit time is small, and the output rate is low, which can only meet the needs of small batch tests

[0005] Another example is the "quick opening" device that is often used in the production of enterprises. Although it has a large diameter and can adapt to the characteristics of solid materials, it is bulky and heavy. It needs a motor to open and close through mechanical transmission. The formation of steam explosion operation requires instantaneous high-pressure release of material, so that the effect of breaking the material will directly affect production efficiency and output quality

[0006] There are also some so-called multi-state material valve reports in the laboratory stage, most of which are not suitable for production practice, and are vulnerable to damage and require a lot of maintenance, so it is difficult to see industrial application
