Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of activated carbon, in particular to a multi-field composite activated carbon deep cleaning device. Background Art
[0002] Activated carbon is a carbon material that has been carbonized and activated. It has a very high surface area and adsorption capacity and is widely used in water treatment, air treatment, chemical separation, medicine, supercapacitors and other fields. The preparation method of activated carbon usually involves heating organic matter (usually wood, coconut shells, coal or waste biomass) at high temperature to carbonize it, and then treating it with an activator (water vapor, carbon dioxide or potassium hydroxide, etc.) to increase its pore structure and adsorption capacity. However, due to the inorganic components and chemical activator residues in the raw materials themselves, the ash content of the product activated carbon is often too high. In order to meet the material purity requirements for applications such as medicine and supercapacitors, further deep cleaning is required.
[0003] Traditional deep cleaning equipment is generally implemented in a single field, which leads to problems such as high residual ash content and long process time. Common activated carbon cleaning and purification is achieved through graded cleaning, which mainly relies on the agitator to provide a shear force field for the turbid liquid formed by the activated carbon and the process fluid, strengthen the relative movement between the material and the fluid to desorb impurities; after a certain process time, the ion desorption reaches a state of equilibrium, and then the plate and frame filter and other equipment are used to obtain preliminary purified materials and then the next level of similar cleaning process is carried out.
[0004] Therefore, the current activated carbon process has many steps, a long process, and a large number of fixed equipment; at the same time, the agitator can only provide shear force for the fluid, and it is not easy to desorb impurities on the surface of the activated carbon. In addition, because the density of activated carbon materials is often lower than that of water, the material floats on the water surface, and the shear force cannot act well on the material. Therefore, how to provide a multi-field composite activated carbon deep cleaning equipment to achieve efficient deep cleaning of activated carbon materials is a technical problem that technicians in this field urgently need to solve.

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.
[0021] See also Figure 1 The utility model proposes a multi-field composite activated carbon deep cleaning equipment, including a shell 1 and a cleaning and stirring assembly, wherein the shell 1 is provided with a feed inlet, a feed outlet, a liquid inlet 8 and a liquid outlet 7; a filter plate 2 is arranged at the bottom of the shell 1, and the liquid outlet 7 is located below the filter plate 2; a heating and heat-insulating layer 6 is arranged outside the shell 1.
[0022] The shell 1 is a hollow structure made of a profile with a certain strength, so that it has a certain volume for accommodating cleaning liquid. The shell 1 is provided with a feed port, a discharge port, a liquid inlet 8 and a liquid outlet 7. As shown in the figure, the liquid inlet 8 and the feed port are provided at the top of the shell 1, and the discharge port and the liquid outlet 7 are provided at the bottom of the shell 1. A filter plate 2 is provided at the bottom of the shell 1, and the liquid outlet 7 is located below the filter plate 2. The filter plate 2 is used to filter the cleaned activated carbon, and the cleaned activated carbon is retained on the filter plate 2 after the cleaning liquid is discharged from the liquid outlet 7.
[0023] In some schemes, the filter plate 2 is connected to the shell 1 by pulling and sliding, that is, the filter plate 2 is inserted into the discharge port, and the cleaned activated carbon trapped on the filter plate 2 can be extracted by pulling the filter plate 2, thereby realizing the discharge of the cleaned activated carbon.
[0024] The cleaning and stirring assembly comprises a stirring member 3 and an ultrasonic cleaning member 4 ; one end of the stirring member 3 extends into the housing 1 and is provided with a paddle 5 ; the ultrasonic cleaning member 4 performs ultrasonic cleaning on the material in the housing 1 .
[0025] One end of the stirring member 3 extends into the shell 1, and the other end is located outside the shell 1, wherein a paddle 5 is provided at one end of the stirring member 3 extending into the shell 1. The stirring member 3 is an automatically retractable rod, and in the extended state, the bottom of the paddle 5 is in contact with the filter plate 2, and the paddle 5 is vertically arranged with the filter plate 2, and the bottom of the paddle 5 is a horizontal plane, therefore, the stirring member 3 can be turned on during the activated carbon cleaning process, so that the paddle 5 rotates around the center of the stirring member 3, and is used to stir the cleaning liquid in the shell 1, so as to achieve the purpose of cleaning the activated carbon. The stirring member 3 provides shearing force for cleaning the activated carbon, promotes the flow of the cleaning liquid, and reaches the desorption equilibrium state at the fastest speed.
[0026] When the activated carbon is cleaned, the cleaning liquid is discharged from the liquid outlet 7. The cleaned activated carbon trapped on the filter plate 2 can be extended by the stirring member 3. The bottom of the paddle 5 is used as a horizontal plane. The paddle 5 is used to squeeze the activated carbon trapped on the filter plate 2 to further reduce the humidity of the activated carbon and make the cleaning liquid discharged from the liquid outlet 7 as much as possible for recycling.
[0027] Among them, the ultrasonic cleaning component 4 includes at least two ultrasonic oscillators of different frequencies; the ultrasonic oscillator can generate high-frequency ultrasonic fluctuations, and the ultrasonic waves emitted by the ultrasonic oscillator in this embodiment can be configured in the frequency range of 20kHz to 400kHz. The ultrasonic oscillator transmits high-frequency ultrasonic fluctuations to the cleaning liquid, and these fluctuations will produce high-intensity pressure changes in the liquid, forming bubbles and causing the formation and instantaneous collapse of bubbles in the cleaning liquid. The collapse of the bubbles produces small vortices and shock waves, and the energy of these vortices and fluctuations can effectively rinse and separate the ash and residual alkali on the surface and inside. For example, in the present application, 2 sets of ultrasonic oscillators of different frequencies are included, one of which emits a fixed ultrasonic wave with a frequency of 40kHz; the other ultrasonic oscillator emits a variable ultrasonic wave with a frequency of 20-40kHz, respectively realizing the composite cleaning of activated carbon with different pore sizes, thereby improving the purification effect.
[0028] In addition, the ultrasonic cleaning component 4 of the present application effectively promotes the relatively stable dispersion of the activated carbon and the cleaning medium, and cooperates with the stirring element 3 to enhance the shearing effect of the stirring paddle on the mixed system. The present application applies the multi-field composite theory, adding ultrasonic field and thermal field to the traditional stirring cleaning to enhance the impurity removal effect.
[0029] In some embodiments, a pneumatic component connected to the housing 1 is also included; wherein the pneumatic component stores high-pressure gas for filter-filtering the activated carbon using the high-pressure gas after the activated carbon is cleaned.
[0030] In the present application, the activated carbon deep cleaning equipment also includes a pneumatic component connected to the shell 1, in which high-pressure gas is stored. When the activated carbon is cleaned, the cleaning liquid is discharged from the liquid outlet 7, and the cleaned activated carbon retained on the filter plate 2 is filtered again using the high-pressure gas storage to further reduce the humidity of the activated carbon. Then the stirring element 3 can be extended, and the bottom of the paddle 5 can be used as a horizontal plane. The paddle 5 is used to squeeze the activated carbon retained on the filter plate 2, and the cleaning liquid is discharged from the liquid outlet 7 as much as possible for recycling.
[0031] In some embodiments, the heating and insulation layer 6 is an electric heating device.
[0032] A heating and insulation layer 6 is arranged outside the shell 1. The heating and insulation layer 6 is an electric heating device, for example, the electric heating device is an electric heating jacket. During the activated carbon cleaning process, the cleaning liquid in the shell 1 can be heated to 50-80°C, thereby increasing the average kinetic energy of the molecular group, enhancing the thermal motion of the impurity ions to make them easier to desorb, and increasing the cleaning cleanliness of the activated carbon.
[0033] The method of using the activated carbon deep cleaning equipment in this application is as follows: turn on the electric heating jacket to keep the equipment at a constant temperature between 50-90°C; add the activated carbon material to be cleaned, and then add the cleaning solution. The cleaning solution can be pure water, hydrofluoric acid, sodium hydroxide solution, hydrochloric acid, etc., and the cleaning concentration is a concentration between 10-50ml per gram of activated carbon material. Turn on the stirring element 3 and the ultrasonic cleaning component 4 to deeply elute the material, and the elution time is between 10-600min. Turn off the stirring element 3 and the ultrasonic cleaning component 4, and fill the vent with compressed gas at a pressure between 5bar-20bar to achieve filter pressing. After the filter pressing is completed, the stirring element 3 can be extended, and the bottom of the paddle 5 can be used as a horizontal plane. The paddle 5 is used to squeeze the activated carbon trapped on the filter plate 2, and finally the product on the filter plate 2 is cleaned and collected.
[0034] If one washing cannot achieve the expected effect, 2-4 steps can be repeated for multi-stage cleaning. The present application only requires one shell 1, which can realize multiple process steps such as water washing, acid washing, alkali washing, plate and frame filter pressing, etc. in combination with program control; it can greatly reduce the number of equipment required for the purification process and reduce the investment in equipment manufacturing. At the same time, multi-field composite deep cleaning can effectively clean the outer and inner surfaces of the activated carbon, minimize residual impurities, reduce process time and improve production efficiency; the cavitation effect caused by the ultrasonic wave emitted by the ultrasonic cleaning component 4 can promote the material and the cleaning liquid to form a stable dispersion system, with low resistance and less wall adhesion during the filter pressing process.
