Description

Reaction kettle for active carbon modification

Technical Field

The utility model relates to a reation kettle equipment field specifically is a reation kettle who is used for active carbon to modify.

Background

In the environmental protection field, activated carbon is used as a common adsorbent in the field of treating various pollutants. Due to the relationship between different water qualities and pollutant properties, the demand for modification of activated carbon is increasing. The modification of activated carbon is usually carried out in a liquid phase, and therefore, the modification of activated carbon is carried out industrially in a reaction vessel.

The modification of activated carbon often requires the addition of a certain amount of chemical agent, even sometimes in excess. From the viewpoint of use, it is preferable that the amount of the chemical agent remaining or adhering to the modified activated carbon is smaller. In general, modified activated carbon and wastewater are conveyed to a filter cloth together for solid-liquid separation, and then are cleaned after the solid-liquid separation, so that the following two problems exist: firstly, when the filtered modified activated carbon stays on the filter cloth, residual chemical substances are difficult to clean thoroughly by water washing due to the accumulation of carbon layers, and the safety of the modified activated carbon cannot be ensured; secondly, if the next modification is carried out in the reaction kettle, the working time and the workload can be greatly increased.

If the modified activated carbon is cleaned in the reaction kettle, the stirring function of the reaction kettle can be utilized, the cleaning is more uniform and thorough, the amount of residual chemical substances is reduced, and the safety of the modified activated carbon is ensured. Meanwhile, if the next reaction process exists, the reaction liquid is directly added into the reaction kettle to start the next reaction, the reaction kettle does not need to be loaded from the filter cloth again, the operation time and labor are saved, and the working efficiency is improved. Therefore, it is very important to improve the structure of the stirred tank reactor. At present, the published invention mainly aims at the aspects of control, transmission, stirring blades and the like of a reaction kettle. For example, in patent application No. CN201120574819.0, the mixing effect of the materials in the radial direction, the axial direction and the circumferential direction is greatly promoted by the advantages of the organic combination of anchor type, paddle type and ribbon type stirrers. The invention discloses a self-adaptive fuzzy dynamic surface control reaction kettle in the patent with the application number of CN201120366450.4, which completely considers the characteristics of strong nonlinearity and unstable open loop of a continuous stirring reaction kettle and can adapt to the working environment of micro drift of the working point of the reaction kettle; the method can better approximate unmodeled dynamic and uncertain items in the continuous stirring reaction kettle system, offset the influence of the factors on the stability of the closed loop system on line, and obtain a simplified self-adaptive fuzzy dynamic surface controller by reverse deduction, thereby improving the control precision and reducing the reaction time of the reaction kettle. However, the scheme for improving the solid-liquid separation efficiency is rare, and although the filter screen with a proper pore size is additionally arranged in the kettle body of the existing reaction kettle, the in-situ solid-liquid separation can be realized without the steps of suction filtration and the like. But the filter screen of installing additional often adopts the inner wall embedded, and installs in the reation kettle bottom, has two aspect problems again like this: firstly, the bottom of the kettle body has larger pressure bearing, and the filter screen is easy to be damaged by impact; secondly, the filter screen easily produces the charcoal layer and piles up, blocks up the filtration pore of filter screen and leads to the waste water to be difficult to get rid of, and these two aspect problems can cause the unable separation of solid-liquid.
