Application example 1
Terahertz automatic regeneration active carbon honeycomb brick and adsorption filter
The filter is used for a maintenance-free adsorption filter and an intelligent closestool odor removal filter (figure 4).
A cross flow fan 32 is arranged in an intelligent closestool 31 with the functions of ventilation and odor removal, and odor in the closestool is extracted to be adsorbed by the activated carbon honeycomb bricks 15 and then blown out from an air outlet 33. The odor removal efficiency of the activated carbon honeycomb brick is obviously reduced only by one or two months, and the odor removal effect can last for 1 to 5 years after the honeycomb brick prepared from the automatically regenerated activated carbon of the invention replaces the original activated carbon honeycomb brick.
An example of the manufacturing process of the automatically regenerated activated carbon honeycomb brick is as follows:
the coal activated carbon powder (50 parts), the terahertz powder (2 parts) and the attapulgite powder (50 parts) are mixed and stirred into mud by adding water. Making into porous green brick by molding machine, and drying in the shade to obtain dry green brick. And (3) putting the dry blank into an airtight furnace, heating the furnace to 700 ℃ for 7 hours, slowly heating the furnace to 850 ℃ for 3 hours, and cooling the furnace. And performing pre-delivery enhanced irradiation on the activated carbon through a terahertz irradiation production line, and detecting that a packaged finished product is delivered from a factory. The production process is not different from the traditional process of the activated carbon brick except that the terahertz powder is added during mixing and the irradiation is enhanced after discharging.
Application example 2
Application of terahertz automatic regeneration activated carbon in paint spraying workshop (figure 5)
The air treatment system of the paint spraying workshop uses three filters, namely a primary filter element, a middle-grade filter element and a honeycomb activated carbon brick 15, wherein the first two filter elements can use terahertz automatic regeneration activated carbon blanket materials to form a primary activated carbon filter element 21 and a middle-grade activated carbon filter element 22.
The manufacturing process of the terahertz automatic regeneration activated carbon cloth comprises the steps of mixing activated carbon powder and terahertz powder according to the proportion of (1) - (10) of 100, producing according to the original process of activated carbon non-woven fabric, and carrying out reinforced irradiation on a finished product.
The terahertz automatic regeneration materials enable the service life of a filter element for treatment in an air injection workshop to be prolonged from three months to half a year for a primary filter element, one year for a middle-grade filter element and 2-3 years for a honeycomb activated carbon brick.
Application example 3
Terahertz automatic regeneration active carbon antibacterial and deodorization mask (active carbon cloth 20)
The mask is odorless after being continuously used for 8-12 hours, has longer service life than a common mask, and is safer and good for doctors.
The terahertz automatic regeneration activated carbon cloth layer is added in the melt-blown cloth of the existing mask, and the terahertz waves can eliminate bacteria attached to materials of all layers on the mask, so that the mask is not smelly after being worn for a long time.
The manufacturing process of the terahertz automatic regeneration activated carbon cloth comprises the steps of mixing activated carbon powder and terahertz powder according to the proportion of (1) - (10) of 100, producing according to the original process of activated carbon non-woven fabric, and carrying out reinforced irradiation on a finished product.
Application example 4

The active carbon adsorbs bacteria, mould spores and peculiar smell molecules, and the terahertz waves decompose the bacteria, the mould spores and the peculiar smell molecules, so that the respective advantages of two main materials are fully exerted: the active carbon has quick response and long terahertz duration.
The forced ventilation effect is better by using the fan. Forced ventilation can make the deodorization effect more rapid, and is irrelevant to the regeneration effect.
The deodorizer can be used in rooms, refrigerators, elevators, etc.

Terahertz automatic regeneration active carbon automatic regeneration frame (2, 43 in figure 7)
This is an atypical application of this patent, which is exactly the same in application range and effect as the terahertz automatic regeneration activated carbon deodorizer of example 4.
The frame uses plastic and terahertz powder, the terahertz powder adopts the terahertz material with the antibacterial, fresh-keeping and smell-removing effects and the preparation method and application thereof, the terahertz material with the antibacterial, fresh-keeping and smell-removing effects is disclosed in Chinese patent ZL201910527213.2, or the terahertz master batch with the terahertz antibacterial, mildew-proof, smell-removing and fresh-keeping functions and the preparation method thereof are disclosed in patent application No. 202010709271X.
The frame size should not be too large. The maximum distance between the activated carbon and the frame is kept between 50 and 70 mm.
The forced ventilation effect is better by using the fan. The ventilation can accelerate the odor removal speed, and is irrelevant to the terahertz automatic regeneration effect.
The terahertz powder used by the invention adopts Chinese patent ZL201910527213.2, namely a terahertz material with antibacterial, fresh-keeping and odor-removing effects and a preparation method and application thereof, and can radiate a certain dose of terahertz waves 5, effectively decompose various organic matters and kill bacteria and mold 4, and the organic matters adsorbed by the activated carbon can be decomposed by the terahertz waves after a period of time. The advantage of doing so is, the active carbon is with faster speed seizure microorganism spore, organic matter and volatile composition, and microorganism spore, organic matter volatile composition are killed and are decomposed by terahertz again, therefore obtained non-maintaining active carbon, have higher speed of removing the flavor and the sterilization effect than simple terahertz material, can reduce its maintenance cost by a wide margin than traditional active carbon, prolong the life (1~ 40 times) of active carbon at double.
The active carbon product can promote adsorption efficiency through terahertz irradiation production line now, and terahertz irradiation production line adopts patent product ZL 201920915589.6.
The foregoing shows and describes the general principles and features of the present invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
