Abstract

The present invention relates to methods for producing and regenerating seamless active carbon products, and a product thereof. The method for producing seamless active carbon products of the present invention comprises the following steps: wood or bamboo is put in a sealed metal container provided with an exhaust port and slowly heated until the temperature of the wood or the bamboo is 38 to 45DEG C at the temperature rise rate of 0.15 to 0.3DEG C per minute; the temperature continues to rise at the same rate, the temperature is kept for 0.5 to 1 hour every time the temperature rises 30 to 50DEG C, and the highest temperature is 600DEG C. If the temperature rise rate is smaller than 0.15DEG C per minute, then the temperature does not need to be kept; when the highest temperature is kept for a preset time period, the temperature is slowly decreased at the same rate until the temperature in the container decreases to the room temperature, and the wood or the bamboo is taken so as to obtain the seamless active carbon product. The method for regenerating seamless active carbon products is the same as the method for producing seamless active carbon products, but the highest temperature of the method for regenerating seamless active carbon products is 400DEG C and the vacuum degree in the container is kept at 0.7 to 0.9Pa. The product of the present invention is the seamless active carbon product made by moulding, coloring and decorating the product of the present invention, and the seamless active carbon product has the product functions of decorations, ornaments, handicrafts, etc., and can adsorb harmful gases in the air so as to purify the air.

Description

The renovation process of gac

Technical field

The present invention relates to the production and the renovation process of gac goods and have finishing, decoration, art, the handicraft product of adsorption function.

Background technology

In the prior art, though people begin to utilize the adsorption function of gac already, it utilizes scope very little, is mainly used in special type protection and laboratory etc.

On the other hand; along with The development in society and economy; it is important further that environment protection seems, the various obnoxious flavoures that hotel guest-room, household's house fitting material discharge, the smog that smoking causes, indoor vitiated air etc. all have a strong impact on the healthy of people, demand urgently purifying.

Summary of the invention

The technical problem to be solved in the present invention is, problem at the prior art existence, a kind of production of product of seamless active carbon and renovation process and products thereof are proposed, utilize described method to produce seamless active carbon and it is regenerated and reuse, goods such as prepared finishing, decoration, art had both had ornamental aesthetic feeling, possessed adsorption function again, significantly decontamination chamber's inner air and outer air, thereby the raising environmental quality is safeguarded HUMAN HEALTH.

One of technical scheme of the present invention, the step of promptly described product of seamless active carbon production method is:

(1) timber or bamboo wood are placed the sealed metal container that is provided with venting port, with the heat-up rate of 0.15-0.3 ℃ of per minute rising by room temperature slowly the described material of heating be incubated 0.5-2 hour to 38-45 ℃; For as the wet feed down, that bamboo is expected of lumbering just, in this intensification and holding stage must be with described containers, be evacuated to 0.8-1.5Pa vacuum tightness;

(2) continue to continue to heat up with above-mentioned identical heat-up rate, the every rising 30-50 of temperature ℃, be incubated 0.5-1 hour, the highlyest rise to 600 ℃; If heat-up rate is lower than 0.15 ℃/min, then need not be incubated;

(3) after the top temperature constant temperature scheduled time, slowly lower the temperature with the speed identical with above-mentioned heat-up rate, temperature is reduced to room temperature in metal vessel, takes out material, promptly gets seamless charcoal piece goods;

In the said process, can before charing, will treat that carbonated material (timber, bamboo wood) is processed into desired structure shape (as ornament, handicraft model), carries out described charing again; Also can after described charing is finished, carbide be processed into desired structure, shape.

Two of technical scheme of the present invention, the step of promptly described product of seamless active carbon renovation process is:

(1) will treat that the regeneration activity carbon product places the sealed metal container that is provided with venting port, speed with 0.15-0.3 ℃ of per minute rising slowly heats described goods to 80-100 ℃ by room temperature, be incubated 0.5-2 hour, simultaneously described metal vessel be evacuated to 0.7-0.9Pa;

(2) continue to heat up with above-mentioned identical speed and bleed to make and keep described vacuum tightness in this metal vessel, promotion to 400 ℃;

(3) after 400 ℃ of insulation and keeping described vacuum tightness 0.5-2 hour, with above-mentioned identical speed cooling, and continue to bleed to make and keep described vacuum tightness in this metal vessel, temperature is reduced to room temperature in metal vessel, stop to bleed, treat to recover in the container to take out regeneration feed behind the normal pressure, promptly finish regenerative process.

Three of technical scheme of the present invention is, with described product of seamless active carbon carry out forming process, painted, and make up processing, make have finishing, decoration, technology class and have the seamless active carbon product of obnoxious flavour in the absorbed air, air purification function.

In the production method of product of seamless active carbon of the present invention (comprising section bar), the concrete heat-up rate that is warming up to 38-42 ℃ by room temperature is determined that by wet degree of doing of employed wood, bamboo wood and volume or weight thereof common humidity is less, volume or weight the greater can heat up slightly hurry up.When smoldering (about 300 ℃ of beginning charings), then heat-up rate can slow down.The top temperature of finishing charing is by the diameter or the thickness decision of seeds and single blocks, usually arborescence hard, diameter or thickness is big, it is high that its top temperature is wanted.After finishing carbonization process, reducing to room temperature, take out carbide, with boring method inspection all charings whether, whether the crack is arranged with the lens examination goods.When with five times of lens examination goods leakless, be seamless active carbon of the present invention.

Among the present invention, for charing person after the first moulding, available graduating with cutter or iron the type of being carved into; For first charing aftershaping person, generally use the graduating with cutter moulding; For extraordinary product or precious product then with photoetching or iron the type of being carved into.Product in actual use, adsorb saturated after, carry out desorption with described technical scheme two, promptly regeneration (resurrection).

As known from the above, the present invention is production and the renovation process and the activated carbon product thereof of product of seamless active carbon, and described method can be produced satisfactory product of seamless active carbon, and described product had both had decorative aesthetics, but the active adsorption indoor harmful gas significantly improves the room air condition again.After testing, product adsorption rate of the present invention reaches standard activity charcoal adsorption rate; Because of product is that seamless active carbon is sturdy and durable, indeformable, be not subjected to burn into to be difficult for catching fire; Raw material sources are extensive, sufficient, and available various wood, bamboo wood (comprising artificial material and matrix material) are produced, and material shape is also unrestricted, and post, tube, piece, plate, the root and stem of certain plants, root etc. all can.
