Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating kilns, in particular to a dry distillation heating kiln. Background Art
[0002] Most of the garbage disposal methods in my country are direct landfilling, which will bring a series of disadvantages after landfilling. Direct incineration of garbage has been very popular in recent years, but it has large investment and high operating costs. The incineration process will produce dioxin pollution, which is not a very good treatment method. At present, the garbage is directly heated and distilled using a heating kiln, and the organic components in the garbage are finally decomposed. The distillation produces combustible gas and charcoal. The whole process is pollution-free. However, the existing distillation heating kiln has a low heat utilization efficiency and consumes energy. Therefore, in view of the above situation, it is urgent to develop a distillation heating kiln that is convenient for material distillation, has high heat utilization, and saves energy, so as to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content
[0003] The utility model aims to provide a dry distillation heating kiln, which is convenient for dry distillation of materials, has high heat utilization rate and saves energy.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A dry distillation heating kiln comprises a kiln body, a heating furnace, a first fire baffle, an exhaust pipe, a burner, a fire baffle, a hood and a second fire baffle, wherein the heating furnace is installed on the outside of the kiln body, two first fire baffles are fixed on the upper inner side of the heating furnace, a second fire baffle is fixed on the left inner side of the heating furnace, a fire baffle is fixed on the right side of the second fire baffle, a plurality of hoods are installed on the fire baffle, a hot air transmission channel is arranged in the hood, a plurality of air outlets connected with the hot air transmission channel are arranged on the hood, and the air outlets are located above the fire baffle, a plurality of burners inserted into the heating furnace are installed on the outside of the heating furnace, and the flame outlets of the burners are located below the fire baffle.
[0006] Preferably, a feed port is arranged at the upper left side of the kiln body, an exhaust pipe connected thereto is installed at the lower side of the heating furnace, and the exhaust pipe is located directly below the feed port.
[0007] Preferably: high temperature resistant heat insulating material is arranged inside the heating furnace.
[0008] The beneficial effects of the utility model are as follows: when the dry distillation heating kiln is used, materials are added into the kiln body, and then, the materials are burned in the kiln body by the burner to generate hot gas, and the flame mixed in the hot gas is shielded by the fire baffle to prevent the flame from directly burning the outer shell of the kiln body. When the hot gas flows upward, it passes through the hot gas transmission channel and the air outlet to enter the heating furnace, so that the heat conduction of the hot gas in the whole kiln body is more uniform, and the kiln body is heated by the hot gas in the heating furnace. The setting of the first fire baffle wall can cause a certain shielding of the flow of hot gas, thereby reducing the circulation speed of the hot gas, increasing the residence time of the hot gas in the heating furnace, reducing the heat being quickly discharged by the air outlet, so as to improve the heating effect of the kiln body, and reduce the amount of gas used by the gas burner. In addition, since the exhaust pipe is arranged directly below the feed port, when adding materials, the hot gas discharged from the exhaust pipe can preheat the materials added at the feed port to improve the heating efficiency. In summary, the utility model is convenient for material dry distillation, has high heat utilization rate, and saves energy. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0015] Specific examples are given below.
[0016] See also Figure 1~Figure 3In the embodiment of the utility model, a dry distillation heating kiln includes a kiln body 1, a heating furnace 2, a first fire baffle 3, an exhaust pipe 4, a burner 5, a fire baffle 6, a hood 7 and a second fire baffle 8. The heating furnace 2 is installed on the outside of the kiln body 1, and the inside of the heating furnace 2 is provided with a high temperature resistant heat insulation material to achieve the function of heat insulation and reduce heat loss. A feed port 101 is provided on the upper left of the kiln body 1, and an exhaust pipe 4 connected thereto is installed on the lower side of the heating furnace 2. The exhaust pipe 4 is located directly below the feed port 101. Two first fire baffles are fixed on the upper side of the interior of the heating furnace 2. Wall 3, the inner upper side of the heating furnace 2 is divided into three parts by two first fire baffles 3, a second fire baffle 8 is fixed to the left side of the interior of the heating furnace 2, a fire baffle 6 is fixed to the right side of the second fire baffle 8, a plurality of hoods 7 are installed on the fire baffle 6, a hot air transmission channel 701 is arranged in the hood 7, a plurality of air outlets 702 connected with the hot air transmission channel 701 are arranged on the hood 7, and the air outlets 702 are located above the fire baffle 6, and a plurality of burners 5 inserted into the interior are installed on the outer side of the heating furnace 2, and the flame outlet of the burner 5 is located below the fire baffle 6.
[0017] Working principle: When the dry distillation heating kiln is used, the material is added into the kiln body 1, and then the gas is burned in the kiln body 1 through the burner 5 to generate hot gas. The flame mixed in the hot gas is shielded by the fire baffle 6 to prevent the flame from directly burning the outer shell of the kiln body 1. When the hot gas flows upward, it passes through the hot gas transmission channel 701 and the air outlet 702 to enter the heating furnace 2, ensuring that the hot gas evenly provides heat to the heating furnace, and the kiln body 1 is heated by the hot gas in the heating furnace 2. The setting of the first fire baffle 3 can cause a certain shielding of the flow of hot gas, thereby reducing the circulation speed of the hot gas, increasing the residence time of the hot gas in the heating furnace 2, and reducing the heat from being quickly discharged through the air outlet, so as to improve the heating effect of the kiln body 1 and reduce the amount of gas used by the gas burner. In addition, since the exhaust pipe 4 is arranged directly below the feed port 101, when adding materials, the hot gas discharged from the exhaust pipe 4 can preheat the material added at the feed port 101 to improve the heating efficiency.
