Description

Technical Field

[0001] The utility model belongs to the technical field of carbonization equipment, and particularly relates to a container-type carbonization device. Background Art

[0002] A carbonization device is a device that carbonizes carbon-containing woody materials such as wood chips, rice husks, peanut shells, plant straws, and tree barks under high-temperature conditions in a carbonization furnace. The carbonization process of woody materials in a carbonization furnace generally can be divided into the following three stages: a drying stage, an initial carbonization stage, and a full carbonization stage. The drying stage starts from ignition until the furnace temperature rises to 160°C. At this time, the moisture contained in the woody materials is mainly evaporated by external heating and the heat generated by its own combustion, and the chemical composition of the woody materials hardly changes. In the initial carbonization stage, part of the heat is generated by the combustion of the woody materials themselves, so that the furnace temperature rises to between 160 and 280°C. At this time, the woody materials undergo thermal decomposition reactions, and their composition begins to change. For example, hemicellulose decomposes to generate substances such as CO2, CO, and a small amount of acetic acid. In the full carbonization stage, the temperature in this stage is 300 to 650°C. In this stage, the woody materials rapidly undergo thermal decomposition, and at the same time, a large amount of liquid products such as acetic acid, methanol, and wood tar are generated; in addition, combustible gases such as methane and ethylene are also generated, and these combustible gases burn in the furnace; the thermal decomposition and gas combustion generate a large amount of heat, which raises the furnace temperature, and the woody materials are carbonized by dry distillation at high temperature.

[0003] Most traditional carbonization equipment uses manual loading and unloading of materials, resulting in high labor costs, and the operating environment temperature of the staff is relatively high, and the operating environment is harsh, affecting the safety of the staff; in addition, in the traditional carbonization process, material preheating, drying, carbonization, and cooling are all completed in the carbonization furnace, resulting in extremely low thermal energy utilization rate of the carbonization process, serious losses, and extremely low equipment utilization rate.

[0028] As Figure 3 shown, the carbonization chamber 11 is provided with a carbonization gas delivery pipe 16. The carbonization gas delivery pipe 16 is connected with a pressure regulator 17. The pressure regulator 17 is connected with a carbonization gas discharge pipe 18. The carbonization gas discharge pipe 18 is provided with at least one carbonization gas discharge port. One of the carbonization gas discharge ports is communicated with the combustion chamber 12. Preferably, the carbonization gas discharge pipe 18 is provided with two carbonization gas discharge ports.

The carbonization furnace has a track-type design and a double combustion chamber 12 design, integrating carbonization, flue gas pretreatment, flue gas combustion and reuse, and flue gas combustion and transportation. It completely avoids and changes the problem in the traditional process that the flue gas is transported by pipes, resulting in the easy condensation of wood tar on the inner wall of the pipes and causing pipe blockage. Moreover, the waste heat after carbonization is directly sent into the preheating and drying chamber to dry the raw materials, and the high-temperature gas after the flue gas combustion can be used by the waste heat boiler or the heat exchanger 20, facilitating the provision of a large amount of heat energy resources for enterprises and units.

[0038] (7) After carbonization is completed, the waste heat air is directly sent to the preheating drying chamber 3 through the waste heat recovery pipeline 7 to heat the material box car 8.

[0039] (8) The carbonized gas generated by carbonization is output through the carbonized gas exhaust pipe 18. According to the process requirements, the low-temperature carbonized gas and the high-temperature carbonized gas are sent to the flue gas purification processor or the combustion chamber 12 in different time periods. The low-temperature carbonized gas is purified by the wood vinegar purification device and then discharged into the air. The high-temperature carbonized gas is sprayed into the combustion chamber 12, and the combustible gas therein provides heat for the carbonization chamber 11.
