The invention relates to the technical field of biomass utilization, and particularly provides a process of preparing high-quality biomass charcoal for carbon-based fertilizer and co-producing wood vinegar. Multi-pore high-quality biomass charcoal and wood vinegar are obtained by adopting a low and medium-temperature cracking mode. Under an anoxic condition, a biomass raw material is carbonized, so that organic carbon in biomass is retained to the maximum extent; the wood vinegar is operated through phase separation of spraying liquid, so that energy waste and flue gas pollution which are caused by combustion are avoided; the low-concentration wood vinegar is further cyclically used as a spraying agent at the same level for recycling, so that effective components in the wood vinegar can beaccumulated. As the obtained wood vinegar is sprayed to the biomass charcoal, the sterilization and parasite expelling effects of the biomass charcoal can be enhanced, and the biomass charcoal is also entitled with nutritional components.

The invention relates to an organic waste processing furnace. The organic waste processing furnace is provided with an L-shaped outer furnace body with a horizontally-extending cavity and a vertically-extending cavity, a tank body is arranged on the vertically-extending cavity, and a burning chamber is directly connected with a heating chamber, so that the occupation space of the L-shaped outer furnace body is greatly reduced, and the structure is more compact. In addition, the outer lateral wall of the tank body is surrounded by a lateral heating channel, and the bottom of the tank body is wrapped and heated by a bottom heating channel; and after high-temperature gas coming from the horizontally-extending cavity enters the vertically-extending cavity, the bottom of the tank body is heated through the bottom heating channel, and meanwhile the lateral wall of the tank body is synchronously heated through a lateral heating channel surrounding the outer lateral wall of the tank body in the circumferential direction, so that all outer walls, located in the vertically-extending cavity, of the tank body can be evenly heated by the high-temperature gas, and meanwhile carbonization of the organic waste in the tank body is more uniform.

The invention provides a material sorting device which comprises a rotary sleeve, a lifting sleeve, a furnace rake, a regular polygon prism and a transmission gear; a first keyway is formed in the external circumferential surface of the rotary sleeve, a key is matched with the keyway, and the rotary sleeve is sleeved on a fixed shaft; a second keyway which is matched with the key is formed in theinternal circumferential surface of the lifting sleeve, and the lifting sleeve is sleeved on the rotary sleeve through the key; the furnace rake is fixedly connected with the external circumferentialsurface of the lifting sleeve, and the regular polygon prism is fixedly connected with the external circumferential surface of the lifting sleeve; and the transmission gear connects a motor with the rotary sleeve, and is fixedly connected with a carbonization furnace body. The material sorting device can enable materials in a carbonization furnace to be uniformly burnt and carbonized; the material sorting device has a function of compacting materials, the materials are carbonized in an appropriate compactness state, so the carbonization quality and production efficiency of straws are ensured;moreover, a limit switch plays the role of automatic feeding of the carbonization furnace; and the material sorting device also has the advantages of simplicity and reasonability in structure, safetyand reliability, and is worth being applied and popularized.

The invention discloses a method for large-scale on-site production of biochar from crop straws. The method comprises the following steps of building a soil pyrolysis tank in an open space, stacking air-dried crop straws on the soil pyrolysis tank according to a certain dimension, burning the crop straws under the condition of enough oxygen in a short time, and fast covering the burning area by soil so that the fire is extinguished completely, wherein by heat produced by combustion of a small part of biomass, under the conditions of low oxygen content and thermal resistance caused by soil covering, the rest of the biomass can be fast pyrolyzed into high-quality biochar. The biochar obtained by the method has the advantages of high yield, good charing uniformity, high charing level and low smoke production amount.

The invention discloses a preparation method of the black pottery, which is characterized in that yellow clay is selected to be ground, and water is added into the yellow clay so as to mix the yellow clay into mud, then the mud is filtered and deposited to be made into strip shape, and the strip- shaped mud is made into a green body in needed shape; the made green body is shady dried for a first time, modified, polished for a first time, drawn, engraved, polished for a second time and shady dried for a second time, then vegetable oil is smeared on the surface of the green body to process the surface of the green body; after that, the green body is put into the kiln body to be fired; when the green body is fired, a fume material of asphalt is added so that the smoke carbon produced by the asphalt is fully absorbed by the green body inside the kiln body. The preparation method has the following advantages: before the black pottery is fired, the surface of the green body is smeared with the vegetable oil so that fine channels are formed in the green body when the vegetable oil is infiltrated into the green body, and the fine channels facilitate the smoke carbon to be infiltrated intothe green body, thereby making the handicraft of the black pottery black and bright from the inside to the outside; at the same time, the pottery smoked by the smoke carbon formed by the asphalt is colorized evenly and has primitive and simple and natural color with smooth and bright surface and fastened color, and does not have the peculiar smell and impurities of the asphalt; and additionally, the preparation method shortens the firing time and saves the energy.

The invention provides a production process of a heat-modified anti-deformation home door panel. The structure of the home door panel consists of a core layer, a middle layer, a balance layer and a finish layer; the production process of the heat-modified anti-deformation home door panel includes the use of MJB‑TF wood stabilizer treats the core slats and middle boards and puts them into a microwave drying kiln for dehydration and carbonization; by using wood stabilizers, the original physical structure of wood (that is, internal stress) is destroyed, and its fiber toughness is increased. Improve the parallel extension tension of its wood fibers, keep the wood stable, and reduce the brittleness of the wood caused by carbonization; add steam rehydration process in the microwave high-frequency carbonization treatment process, so that the carbonization degree of each part of the board is more uniform, effectively improve the dimensional stability, and maintain the board All mechanical properties are stable.
