Problems solved by technology

However, this method has the following technical problems: this process cannot deeply purify the pyrolysis gas, resulting in high impurities in the flue gas after pyrolysis gas combustion, which requires further purification, resulting in increased operating costs, and it is difficult to meet the requirements of the pyrolysis gas after amplification. The internal combustion engine requires gas quality, and the entire seal adopts a mechanical seal, which has a poor sealing effect and poses a safety hazard

Embodiment Construction

[0027] Reference below figure 1 with figure 2 The biomass pyrolysis method according to an embodiment of the present invention is described.

[0028] Such as figure 1 As shown, the biomass pyrolysis method according to the embodiment of the present invention may include the following steps: S1. The biomass is fed into the pyrolysis device 2. The pyrolysis device 2 is liquid-sealed and then pyrolyzed to obtain pyrolysis oil and gas and heat. Decarbonization. The pyrolysis device 2 does not have strict requirements on raw materials, and can meet the requirements for processing raw materials of different shapes. The pyrolysis device 2 includes a material frame, and different material frames are selected for different raw materials. According to the characteristics of the material, when used to process granular materials with a particle size of ≥1mm, the material frame uses mesh material frames with different apertures; when used to process powder materials, the material frame uses...

Abstract

The invention discloses a biomass pyrolysis method and a system implementing the biomass pyrolysis method. The biomass pyrolysis method comprises the following steps of S1, sending biomass to a pyrolysis device, sealing the pyrolysis device with liquid and then performing pyrolysis, so as to obtain pyrolysis oil gas and pyrolysis char; S2, sending the pyrolysis oil gas to a cooling device for cooling, so as to obtain pyrolysis oil and pyrolysis gas; S3, sending the pyrolysis gas to a filter device for filtering; and S4, storing the filtered pyrolysis gas in a gas storage device. According to the biomass pyrolysis method, tar and impurities contents in the pyrolysis gas are reduced through a physical cooling method, therefore, deep purification demand is met, and very high running cost caused by a chemical method is prevented. In addition, the pyrolysis device is sealed with liquid, so that on the one hand, the sealing effect is better than that of mechanical sealing, and operation is fast and convenient, and on the other hand, once the pressure of a hearth is ultra-high, the pressure can be released timely, so that the system is safe and reliable.

Description

Technical field [0001] The present invention relates to the technical field of biomass pyrolysis, in particular to a biomass pyrolysis method and a system for implementing the same. Background technique [0002] The thermochemical conversion (such as carbonization, pyrolysis, gasification) of biomass and other viscous carbonaceous materials (such as oil field oily sludge, mineral dust sludge, industrial sludge, hazardous waste liquid) can produce solid, liquid and gaseous products These products can be made into energy forms that are recyclable, easy to use, easy to transport and easy to store according to demand, and can be used for thermal power generation or as raw materials for chemical and other industries. According to different raw materials and the difference of heat treatment purposes, carbonization, gasification, pyrolysis, liquefaction or other related thermochemical reactions and processes can be used. [0003] There are many types of reactors used in pyrolysis, such a...
