Problems solved by technology

[0006] Although the disclosure of the above-mentioned patent discloses the technical scheme of using apricot shells as the original pyrolysis to provide refined wood vinegar, the whole process is time-consuming and laborious, especially the refined part of the wood vinegar must be left to stand for 30 days at first, after layering Afterwards, the traditional wood vinegar was still used for heating and refining, and its production efficiency was greatly slowed down and delayed; and one of the considerable advantages of wood vinegar is the comprehensive balance of various organic components, which retains the middle layer of rectification after standing , it is a pity that the organic components contained in the discarded upper and lower layers are wasted

Embodiment 1

[0034] Weigh 1000g of apricot shells into the dry distillation kettle and continue heating with 1KVA power. As the temperature rises, the apricot shells are heated and decomposed. When the temperature in the retort reaches 120°C, apricot shells will be pyrolyzed to produce flue gas. After the flue gas is condensed, crude wood vinegar can be obtained, and the charcoal remains in the retort.

[0035] The present invention collects distillates at different temperatures separately. When the temperature in the retort is between 120°C and 170°C, this is the first collection temperature stage, and 40.80g of distillate is collected. The content of antibacterial active ingredients in this section is relatively low, and the main For water. When the temperature in the retort is 170°C to 370°C, this is the second collection temperature stage, and 338.64g of distillate is collected. There are many types of components in this temperature section, and the content of antibacterial active ingredie...

Embodiment 2

[0039] After the ripe mountain apricot seeds are air-dried, the shells are broken and sorted to obtain bitter almond and apricot shells.

[0040] Weigh 1500g of apricot shells into the dry distillation kettle and continue heating with a power of 1.2KVA. As the temperature rises, the apricot shells are heated and decomposed. When the temperature in the retort reaches 120°C, apricot shells will be pyrolyzed to produce flue gas. After the flue gas is condensed, crude wood vinegar can be obtained, and the charcoal remains in the retort.

[0041] The present invention collects fractions at different temperatures separately. When the temperature in the retort is between 120°C and 170°C, this is the first collection temperature stage. 54.80g of distillate is collected. The content of antibacterial active ingredients in this stage is relatively low. For water. When the temperature in the retort is 170℃~350℃, this is the second collection temperature stage, 306.54g of distillate is collect...

Embodiment 3

[0045] After the ripe apricot seeds are air-dried, the shells are broken and sorted to obtain almonds and apricot shells.

[0046] Weigh 800g of apricot shells into the dry distillation kettle and continue heating with 0.8KVA power. As the temperature rises, the apricot shells are heated and decomposed. When the temperature in the retort reaches 120°C, apricot shells will be pyrolyzed to produce flue gas. After the flue gas is condensed, crude wood vinegar can be obtained, and the charcoal remains in the retort.

[0047] The present invention collects fractions at different temperatures separately. When the temperature in the retort is between 120°C and 180°C, this is the first collection temperature stage, and 25.80g of distillate is collected. The content of antibacterial active ingredients in this stage is relatively low. For water. When the temperature in the retort is 240℃~300℃, this is the second collection temperature stage, and 280.50g of distillate is collected. There are...

Abstract

The invention discloses a method for preparing pyroligneous by utilizing apricot shells and preparation of apricot shell active carbon based on the method. The method uses seeds of almonds as raw materials and prepares natural and environmental-friendly apricot shell pyroligneous as a bacteriostatic agent and the active carbon as a byproduct through the steps of breaking the shells, grinding, pyrolyzing, removing impurities, standing still, refining, and the like. The prepared pyroligneous has medicinal effects and quite wide application space in various industries such as bacteriostasis, antisepsis, deodorization, plant growth promotion, beverages, cosmetics, and the like. The active carbon as the byproduct has powerful adsorption capacity and is widely applied to the aspects of food industries, decolorization, air purification, deodorization, catalyst carriers, precious metal purification, electric conductors, and the like so as to further facilitate the life of people. The method has quite important social, environmental protection and economic benefit.

Description

Technical field [0001] The invention belongs to the technical field of plant extraction, and relates to the extraction and preparation of wood vinegar liquid, in particular to a method for preparing wood vinegar liquid by using apricot shells, and the preparation of apricot shell activated carbon based on the method. Background technique [0002] Wood vinegar is a natural extract obtained from the fractional distillation of flue gas in the process of pyrolysis and carbonization of wood materials. It is a complex, diverse and relatively stable system substance. Wood vinegar is generally light brown to dark brown translucent liquid, with unique smoky aroma, sour taste, PH value 1.5~3.7, specific gravity 1.0025; it contains more than 200 organic substances, including phenols, acids, alcohols, and ketones Etc., complex ingredients, diverse functions, and numerous trace material factors maintain a natural balance. [0003] The biological activity of wood vinegar is diverse and it has ...
