[0003] The patent with publication number CN205528596U provides a dry distillation type internal heating carbonization furnace, and wood gas after cooling is directly sent to the combustion cylinder through a wood gas pipeline. The device has the following disadvantages: before wood is heated to the temperature at which wood gas is generated, the energy used for wood heating can only be provided by the outside world, and then the energy is switched to wood gas. Therefore, the device is inconvenient to operate, and the energy saving effect is not good. UTILITY MODEL CONTENT

[0021] Preferably, the condensing tank is condensed by a circulating water system, and the circulating water system comprises a circulating water sandwich layer arranged on the condensing tank.

[0022] The charcoal dry distillation equipment has the following technical effects compared with related technologies:

[0023] When the charcoal dry distillation equipment starts to work, the wood gas product generated in the last dry distillation is pre-stored in the collecting bag, and under the suction of the pump body, the pre-stored wood gas is directly supplied to the combustion machine, without using external energy and without energy switching. Therefore, the charcoal dry distillation equipment reduces the use of external energy, improves the energy-saving effect, avoids the energy switching in the dry distillation process, simplifies the operation process, improves the operation convenience, and avoids the uncontrolled temperature of the dry distillation tank due to energy switching.

[0024] In the preferred scheme of the utility model, the collecting bag comprises a bottom shell and an upper cover, and an upper edge of the bottom shell is fixed with a water tank one. A lower edge of the upper cover is arranged in the water tank one. After water is injected into the water tank one, the upper cover is placed into the water tank one, so that the lower edge of the upper cover is located below the liquid surface of the water tank one, thereby filling the gap between the upper cover and the bottom shell with water to realize sealing.

DETAILED DESCRIPTION

[0029] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0030] The utility model aims at providing a charcoal dry distillation equipment to improve the operation convenience and energy-saving effect.

[0031] In order to make the above-mentioned purposes, characteristics and advantages of the utility model more obvious and easy to understand, the utility model will be further described in combination with the drawings and specific embodiments.

[0032] REFERENCE Figure 1 The embodiment provides a charcoal dry distillation equipment 100, which comprises a kiln body 1, a dry distillation tank 2, a condensation tank 3, a collecting bag 5, a pump body and a combustor 7.

[0033] The kiln body 1 has a combustion chamber 9 and a heating cavity. The dry distillation pot 2 is at least partially located in the heating cavity. The dry distillation pot 2 is used to contain wood. The condensation pot 3 is connected to the dry distillation pot 2 through a flow guide pipe 1 4 to receive wood gas and wood vinegar and cool the wood gas and wood vinegar. The collection bag 5 is connected to the gas outlet of the condensation pot 3 through a flow guide pipe 2 10 to collect wood gas. The pump body (not shown in the figure) is connected to the collection bag 5 through a flow guide pipe 3 to pump wood gas. The combustion machine 7 is connected to the pump body through a flow guide pipe 4 to obtain wood gas as fuel. The combustion machine 7 has a fire spouting end for extending into the combustion chamber 9.

[0034] The principle of the charcoal dry distillation device 100 in this embodiment is as follows:

[0035] When the charcoal dry distillation device 100 starts to work, the wood gas product of the last dry distillation is pre-stored in the collection bag 5. Under the pumping of the pump body, the pre-stored wood gas is directly supplied to the combustion machine 7 for use, without using external energy and without energy switching.

[0036] Therefore, the charcoal dry distillation device 100 reduces the use of external energy, improves the energy saving effect, avoids energy switching during the dry distillation process, simplifies the operation process, improves the operation convenience, and avoids the uncontrolled temperature of the dry distillation pot 2 due to energy switching.

[0037] After the fire spouting end of the combustion machine 7 is ignited, the dry distillation pot 2 is heated to a set temperature and then the ignition is stopped. After that, the dry distillation pot 2 naturally cools down to a safe temperature (for example, below 40 degrees Celsius) to obtain charcoal.

[0038] As a possible example, in this embodiment, the charcoal dry distillation device 100 further includes a liquid collection pool 6 connected to the liquid outlet of the condensation pot 3 through a flow guide pipe 5 1 1 to collect wood vinegar.

[0039] It can be understood that the liquid outlet of the condensation pot 3 should be lower than the gas outlet to achieve gas-liquid separation.

[0040] As a possible example, in this embodiment, at least part of the flow guide pipe 1 4, the flow guide pipe 2 10, the flow guide pipe 3, the flow guide pipe 4, and the flow guide pipe 5 1 1 (these pipes are collectively referred to as flow guide pipes) has a sandwich layer to circulate water.

[0041] The circulating water circulates and carries away heat through the sandwich layer to cool the flow guide pipes. The flow guide pipes are preferably galvanized pipes to improve the anti-corrosion ability.

[0042] Valves can be installed on the flow guide pipes to achieve on-off control of the flow guide pipes and improve safety. The valves can be manual valves or other types of valves such as electromagnetic valves.

[0043] As a possible example, in the embodiment, the collecting bag 5 comprises a bottom shell and an upper cover, and a water tank I is fixed to the upper edge of the bottom shell. The lower edge of the upper cover is arranged in the water tank I.

[0044] After water is injected into the water tank I, the upper cover is placed in the water tank I, and the lower edge of the upper cover is below the liquid level of the water tank I, so as to fill the gap between the upper cover and the bottom shell with water and realize sealing.

[0045] Compared with the sealing mode using a sealing ring, the sealing effect of water is better, and there is no problem such as thermal aging and aging cracking, the cost is low, and the cooling effect is also achieved.

[0046] As a possible example, in the embodiment, the upper cover can float up and down in the water tank I.

[0047] After water is injected into the water tank I, the initial state of the upper cover is floating. After the charcoal dry distillation device 100 starts to work, the pre-stored wood gas in the collecting bag 5 is directly supplied to the combustor 7 under the suction of the pump body, and the gas pressure in the collecting bag 5 is reduced.

[0048] Since the collecting bag 5 is sealed by water, the upper cover has a certain up-and-down floating space. When the wood gas in the collecting bag 5 is sucked away, the upper cover can sink to adapt to the volume change of the wood gas in the collecting bag 5.

[0049] Compared with the volume-fixed collecting bag 5 sealed by a sealing ring, the volume of the collecting bag 5 of the embodiment is adjusted by the sinking of the upper cover in water, which ensures the sealing property and reduces the internal and external pressure difference, thereby avoiding deformation of the bottom shell and the upper cover under pressure.

[0050] The above technical solution of the embodiment does not use the method of introducing air into the collecting bag 5 to reduce the internal and external pressure difference, which ensures the purity of the wood gas supplied to the combustor 7 and reduces the risk of explosion.

[0051] As a possible example, in the embodiment, the collecting bag 5 further comprises a positioning block, which is located in the water tank I and used for positioning the upper cover.

[0052] When the upper cover sinks to a certain height, the upper surface of the positioning block is contacted, so as to position the upper cover.

[0053] For example, the positioning block has a mesh to reduce the material, reduce the weight, and reduce the cost.

[0054] As a possible example, in the embodiment, the dry distillation tank 2 comprises a tank bottom and a tank top, and a water tank II is fixed to the upper edge of the tank bottom, and the lower edge of the tank top is arranged in the water tank II.

[0055] The dry distillation tank 2 is also sealed by water. The sealing is achieved by placing the tank top into the water tank 2, without the need of screwing or using fasteners, which not only reduces the processing cost, but also makes the opening and closing of the dry distillation tank 2 more convenient.

[0056] As a possible example, in the embodiment, the upper end of the kiln body 1 is provided with an opening, the lower part of the dry distillation tank 2 extends into the heating cavity through the opening, and the upper part of the dry distillation tank 2 extends out of the kiln body 1.

[0057] The upper end of the kiln body 1 is provided with an opening, and the air outside the kiln body 1 can enter the combustion chamber 9 below through the opening, thereby supplying oxygen to the combustion chamber 9.

[0058] Moreover, the tank top of the dry distillation tank 2 is exposed from the top of the kiln body 1, which facilitates the opening and closing of the tank top, and facilitates the placing of wood into the dry distillation tank 2 and the taking of charcoal out of the dry distillation tank 2.

[0059] As a possible example, in the embodiment, the upper end of the dry distillation tank 2 is provided with a temperature gauge 8.

[0060] The temperature gauge 8 is located at the top end of the dry distillation tank 2, so the temperature gauge 8 is located outside the kiln body 1, and the temperature measured by the temperature gauge 8 is the temperature of the dry distillation tank 2 rather than the temperature inside the kiln body 1, which avoids the influence of the kiln body 1 on the measurement result, thereby enabling a more accurate understanding of the temperature of the dry distillation tank 2.

[0061] The operator adjusts the power of the pump body according to the difference between the temperature displayed by the thermometer and the preset process temperature, thereby adjusting the flow of wood gas at the combustion machine 7, so that the temperature displayed by the thermometer approaches the process temperature.

[0062] As a possible example, in the embodiment, the condensation tank 3 is condensed by a circulating water system, and the circulating water system includes a circulating water interlayer arranged on the condensation tank 3.

[0063] The circulating water system enables the circulation of water flow, thereby taking away the heat of the condensation tank 3, and achieving the cooling of the wood gas and wood vinegar liquid in the condensation tank 3. The circulating water system generally includes a water pool, a circulating passage and a circulating pump, the two ends of the circulating passage are connected to the water pool, the circulating pump is arranged on the circulating passage, and the circulating water interlayer is part of the circulating passage. It can be understood that the circulating water interlayer can also be replaced by a heat exchange pipe.

[0064] As a possible example, in the embodiment, the kiln body 1 and the dry distillation tank 2 each include a support and a heat preservation inner lining fixed to the support. The material of the support is preferably fire-resistant steel, and the material of the heat preservation inner lining is preferably aluminum silicate. The bottom shell and the upper cover of the collection bag 5 are preferably made of PVC, which has a small density and facilitates the floating of the upper cover in the water tank 1. The combustion machine 7 is preferably made of fire-resistant steel, and the end of the combustion machine 7 used for abutting the end of the flow guide pipe 4 is preferably a galvanized iron pipe.

[0065] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above examples are only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
