Method and device for rapid entry and exit of solid materials in high-pressure containers

Abstract

The invention discloses a method and a device for quickly entering and exiting solid materials in a high-pressure container. Through the specially designed box-type, inverted V-type feed valve and lantern-type, r-type discharge valve, the high-pressure container is especially suitable for the rapid entry and exit of solid materials, thus avoiding the fragility and frequent replacement of the valve caused by the use of conventional liquid valves. At the same time, it reduces the time required for solid materials to enter and exit the container, improves the processing speed, and increases the benefits. The invention can typically be used in intermittent steam explosion tanks, solid material steaming tanks, solid material sterilizing tanks, etc., and provides suitable equipment selection for the increasing high-temperature and high-pressure treatment of solid materials.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to a method and a device for quickly entering and exiting solid materials in a high-pressure container. Background technique [0002] Generally speaking, the chemical reaction rate increases with the increase of temperature, and the temperature of the reaction system is generally limited under normal pressure, so many chemical reactions are carried out in high-pressure containers with a certain pressure. The early chemical production was mainly based on petrochemical industry. Most of the petrochemical reaction raw materials were in liquid state. Therefore, most of the traditional high-pressure vessels used pipelines to enter and exit materials, and ball valves were often used for the transportation of these liquid materials. control structure. However, such a structure is often not suitable for the treatment of solid materials. Now with the reduction of oil reserves,...

Problems solved by technology

The invention with the application number of 200710141271.9 proposes a new steam explosion system design. Its main idea is to make the opening of the valve as large as possible to ensure the steam explosion speed is fast, but this design guarantees The steam explosion speed, but the power of the steam explosion is too large, so the steam explosion tank can only be made very small, and cannot be enlarged. In fact, the effect of the steam explosion process is not only reflected in the steam explosion speed. Excessive emphasis on the steam explosion speed will only lead to go astray

[0004] ZL200720079330.X also noticed the problems existing in the discharge of ordinary steamed balls, and proposed the idea of ​​installing a control valve to solve the discharge problem. Although this method is effective to a certain extent, the valves used are also ordinary pneumatic ball valves. This will inevitably encounter the same problem as steam explosion equipment

[0005] ZL200720200703.4 also noticed the problems of ordinary steam ball feeding, and proposed a quick-opening structure, which has been widely used in various pressure vessels, such as the pressure vessel mentioned in ZL200920127353.2 and ZL02100176.6 The solid-state fermenter in the middle, although this kind of quick-opening structure is widely used, but the mechanism is complicated, and the opening and closing require motor operation, which is not convenient enough to use
