Description

Technical Field

[0001] The utility model relates to the technical field of wood vinegar liquid treatment, in particular to a wood vinegar liquid treatment device special for kilns. Background Technique

[0002] Wood vinegar liquid is an acidic liquid with a pH of about 3 and acetic acid as the main component. Generally, wood vinegar liquid is obtained by liquefying the smoke emitted during the process of turning wood into charcoal. Since wood vinegar liquid has functions such as soil improvement, deodorization, impregnation of smoked products, plant growth regulator, food preservation, healthcare, beverage additive, feed additive, etc., the production requirements for wood vinegar liquid are getting higher and higher. The raw materials for producing wood vinegar liquid are mainly the leftovers after rough processing of wood or agricultural and forestry waste. Generally, they are burned, and then the gas generated in the combustion furnace is concentrated and liquefied to obtain a liquid mixture with quite complex components, and then the components are separated and refined to obtain wood vinegar liquid.

[0003] In a device for producing wood vinegar liquid from agricultural and forestry waste disclosed in CN 217868727U, in the utility model, an exhaust pipe, a first conical surface and a fixing ring are arranged on one side of the combustion furnace, and a connecting pipe and a second conical surface are arranged on one side of the condenser. Thus, the user can insert the first conical surface into the second conical surface, then tighten the fastening nut and make its interior abut against the fixing ring. When one side surface of the fixing ring contacts one side surface of the connecting pipe, the sealing performance between the combustion furnace and the condenser is the best at this time. This design is convenient for solving the problem of gas leakage at the connection between the combustion furnace and the condenser. However, this device only cools the gas of the combustion furnace through the condenser, and the condensation method takes a long time with fewer ways. The flue gas of the combustion furnace directly enters the condenser, and the large temperature difference will cause damage to the pipeline, and the high heat of the combustion furnace is not convenient to recycle.
