Problems solved by technology

However, the traditional activated carbon impregnation modification production process is complex in operation, low in process efficiency, long in production cycle, large in material loss and poor in activated carbon loading effect
At the same time, the lack of scientific process connection and equipment layout between different processes leads to problems such as large footprint, high noise, large environmental pollution, and high emissions.

preparation example Construction

[0061] The invention provides a kind of preparation method of supported activated carbon, comprises the following steps:

[0062] Vacuumize the reaction kettle equipped with activated carbon, and then introduce the impregnating liquid into the reaction kettle for impregnation treatment to obtain supported activated carbon.

[0063] The invention carries out vacuum treatment on the reactor equipped with activated carbon. The present invention has no special limitation on the activated carbon, and the activated carbon well known to those skilled in the art can be used; in the present invention, the activated carbon preferably includes DDT-046 formula activated carbon or DDT-030 formula activated carbon, wherein, at a temperature of 25°C , Air pressure 101.325KPa, the index parameters of described DDT-046 formula activated carbon and DDT-030 formula activated carbon are shown in Table 1; The measuring method of each index is specifically as follows:

[0064] pH: After mixing 10g...

Embodiment 1

[0082] use figure 1 with 2 The device prepares loaded activated carbon, comprising the following steps:

[0083] Connect the reactor 3 and the vacuum pump 1 through a conduit with a valve 2, put activated carbon (DDT-046 formula activated carbon, see Table 1 for specific index parameters) in the reactor 3, and seal the reactor 3 with a sealing plug; then turn on the vacuum pump 1. Vacuumize the reaction kettle 3 (calculate the vacuum through the pressure indicated by the pressure gauge 4, and the vacuum degree is 0.05MPa), close the valve 2 and then turn off the vacuum pump 1, and maintain the vacuum in the reaction kettle 3 for 30 minutes; Ethylenetriamine aqueous solution, the mass fraction of diethylenetriamine is 13.3%; the mass ratio of activated carbon to impregnating liquid is 1:3) into the dispensing box 5, remove the vacuum pump 1, connect the reaction kettle 3 to the dispensing box 5, Open the valve 2, and use the pressure difference to introduce the impregnating l...

Embodiment 2

[0085] The supported activated carbon was prepared according to the method of Example 1, the difference being that when the reactor 3 was vacuumed, the degree of vacuum was 0.04MPa.

Abstract

The invention relates to the technical field of activated carbon loading, in particular to a loaded activated carbon and a preparation method and device thereof. The preparation method of the loaded activated carbon comprises the following steps of: vacuumizing a reaction kettle filled with activated carbon, and then introducing an impregnation liquid into the reaction kettle for impregnation treatment to obtain the loaded activated carbon. According to the method, vacuumizing treatment is carried out on the reaction kettle filled with activated carbon, the air pressure in the activated carbonpore channels is reduced, so that a negative pressure environment is formed in the activated carbon pore channels, the mass transfer process of activated carbon impregnation is enhanced through differential pressure, active components in the impregnation liquid can be promoted to be uniformly adsorbed to adsorption sites on the surface of activated carbon, the loading capacity of the active components in the activated carbon is improved, and the obtained loaded activated carbon is good in performance; the method provided by the invention is simple to operate and high in production efficiency,the whole preparation process is carried out in a sealed environment, no activated carbon dust or chemicals escape, and the requirement of clean production is met.

Description

technical field [0001] The invention relates to the technical field of activated carbon loading, in particular to a loaded activated carbon and a preparation method and device thereof. Background technique [0002] With the rapid development of my country's economy and the improvement of living standards, people's requirements for indoor environment are getting higher and higher. With the decoration and the use of a large number of furniture accessories, a large number of chemical pollutants flood the indoor environment such as offices, conference rooms, and homes, posing serious harm to the human body. Indoor air pollution has become one of the issues of great concern to human beings, especially formaldehyde pollution is the most representative. [0003] Formaldehyde, also known as formaldehyde, is a colorless irritating gas that is irritating to human eyes and nose. Formaldehyde is the most common indoor air pollution poison. At present, formaldehyde has been identified...
