The device comprises a feed hopper (14), one or more pyrolysis tubes (1), one or more carbon discharge tubes (2) arranged corresponding to the pyrolysis tubes (1), and one or more carbon discharge bins (13) arranged corresponding to the carbon discharge tubes (2), inletsof the one or more pyrolysis tubes (1) are respectively connected with a feed hopper (14); an outlet of the pyrolysis pipe (1) is connected with an inlet of the corresponding carbon outlet pipe (2); outlets of the carbon discharging pipes (2) are connected with the corresponding carbon discharging bins (13), spiral propellers (7) are arranged in the pyrolysis pipes (1) and the carbon discharging pipes (2) respectively, and a temperature difference power generation device (17) is arranged outside the pyrolysis box (3) and comprises a heat collector (22), a temperature difference power generation piece (23) and a plurality of through prismoids (24). The problem that materials are blocked in the reaction process is solved, and heat energy of smoke is fully utilized.

Description

technical field [0001] The invention relates to a pyrolysis furnace, more specifically to a horizontal biomass pyrolysis furnace propelled by an auger containing a thermoelectric power generation device, belonging to the technical field of biomass pyrolysis. Background technique [0002] Biomass pyrolysis technology refers to the pyrolysis of biomass into pyrolysis gas and solid carbon, which can transform biomass into clean gas or liquid fuel, and has become a new energy source that is prioritized by countries around the world. Biomass has the characteristics of wide source of raw materials, low production cost, ecological safety, and no pollution. Moreover, my country's biomass resources are very rich, widely distributed, and sustainable supply. Therefore, biomass pyrolysis technology can be widely promoted. [0003] At present, the existing biomass pyrolysis equipment is relatively simple, and the continuous operation of the pyrolysis furnace has the defects that the mate...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing biomass pyrolysis equipment is relatively simple, and the continuous operation of the pyrolysis furnace has the defects that the material flow is not smooth, easy to block, and the process is difficult to control. Specifically, the following problems generally exist: 1. Raw materials and pyrolysis The product flow is not smooth, it is easy to block the device or produce material accumulation in the device. It is called a mobile device or a continuous production device, but it cannot be continuously produced and operated.

2. It is impossible to effectively control the process parameters. Although some devices are equipped with testing instruments and meters, process data can be obtained, but limited to the design of the device, it is impossible to accurately control the process parameters, and it is difficult to obtain high-quality products. Effectiveness of the device discounted sex

3. The maintainability of the device is too poor. Once blockage or leakage occurs, a lot of effort must be used to solve the problem, which takes time and effort and causes destructive damage to the device; at the same time, there is a large amount of energy in the pyrolysis process loss
