Technical Field

[0001] The utility model relates to the technical field of biomass conversion, in particular to a biomass gasification heat-charcoal cogeneration water circulation device. Background Art

[0002] Biomass gasification and heat-charcoal cogeneration is a thermochemical reaction that uses oxygen or oxygen-containing substances in the air as a gasifying agent to convert the combustible part of biomass fuel (mostly crop straw) into biochar, pyrolysis gas, wood tar, wood vinegar and other products under high temperature conditions. Biomass charcoal and gas cogeneration can be used to solve the recycling of rural straw. The obtained biochar is a clean and renewable energy source that can be used as fuel and can also be used to process charcoal-based fertilizers.

[0003] In the prior art, when the thermal reaction of biomass gasification and heat-to-charcoal cogeneration is carried out, sufficient water vapor needs to be provided to maintain the reaction. However, at the same time, the gasification and heat-to-charcoal reaction itself will also produce a large amount of water vapor. Generally speaking, when the reaction is carried out, the water vapor generated by fresh water source will be directly introduced from the outside, which will cause a waste of the usable water vapor generated by the reaction. Therefore, a biomass gasification and heat-to-charcoal cogeneration water circulation device is proposed to solve the above problem. Utility Model Content

[0009] Preferably, the post-processing assembly includes a filter tank and a treatment box respectively fixedly connected to the upper surface of the installation floor, the filter tank and the treatment box are connected through a pipeline, and the filter tank is connected to the separation tower through a pipeline.

[0010] Preferably, the bottom surface of the filter pool is set to be inclined, the inner wall of the filter pool is detachably connected with a filter mesh plate, the inner bottom wall of the treatment box is detachably connected with a partition mesh plate, the inner bottom wall of the treatment box is respectively provided with a PP cotton layer and an activated carbon adsorption layer, and the treatment box is connected to the water inlet end of the steam generator through a pipeline.

[0011] The utility model provides a biomass gasification heat-charcoal cogeneration water circulation device through improvement, which has the following improvements and advantages compared with the prior art:

[0012] Firstly, the utility model can transport the water vapor produced by the reaction back to the gasification furnace by setting a steam generator and a positive gas circulation pipe, and reuse it as a reaction auxiliary raw material. Compared with directly using external supply, the device saves more water resources and is more economical;

[0013] Secondly, the utility model sets up a separation tower.

The water vapor and other combustible gases can be effectively separated, and the combustible gases can be collected without wasting resources.

[0014] Thirdly, in the utility model, by setting up a filter pool and a treatment box, the condensed water will flow into the filter pool, and some impurities contained in the condensed water will be filtered out. After passing through the treatment box, the PP cotton layer and the activated carbon adsorption layer will be used for further purification, thereby ensuring the purity and cleanliness of the water used as the raw material of the steam generator, preventing impurities from affecting the reaction, and ensuring the effect of the reaction.

[0025] By means of the above structure or mechanism: in the process of biomass gasification, usually under certain thermodynamic conditions, with the help of air medium (air, oxygen, water vapor, etc.), the polymers of biomass are cracked, and finally combustible gas can be obtained. The device is provided with a steam generator 6 as a water vapor output element to ensure sufficient water vapor.

[0026] Furthermore, a recovery pipe 8 is provided on the upper surface of the separation tower 3, and the recovery pipe 8 is connected to an external collecting device.

[0027] By means of the above structure or mechanism: the external collection device refers to a device for collecting some available combustible gases, which belongs to the prior art. This part of the combustible gas needs to be processed before it can be used. This device does not make any changes to this part, so it will not be repeated.

[0028] Furthermore, the separation condensation component 4 includes a water spray condensation plate 401 fixedly connected to the inner walls on both sides of the separation tower 3, a water spray nozzle 402 is provided on one side of the water spray condensation plate 401, the water spray condensation plate 401 is connected to an external water supply device, and a separation mesh plate 403 is fixedly connected to the inner wall of the separation condensation component 4.

[0029] By means of the above structure or mechanism: the interior of the water spray condensation plate 401 is hollow, and the water spray condensation plate 401 can be connected to an external water supply device through a pipeline, and the water entering is sprayed out through the water spray nozzle 402 and contacts with the mixed gas.

[0030] Furthermore, the separation condensation component 4 also includes a separation motor 404 fixedly connected to the bottom of the separation tower 3 , and a separation blade 405 is fixedly connected to the output end of the separation motor 404 .

[0031] By means of the above structure or mechanism: the bottom of the entire separation tower 3 is conical, which is convenient for collecting the condensed liquid water, and when the separation blades 405 rotate, they work together with the water sprayed from the water spray condensation plate 401 to blow away the gas, so that the gas can fully contact with the condensed water, and the high-temperature water vapor is condensed into liquid, while other gases, driven by the airflow of the separation blades 405, enter the recovery pipe 8 and are collected.

[0033] By means of the above structure or mechanism: the condensed water coming out of the separation tower 3 will have some dirt of carbonized biomass remaining due to the high temperature thermal reaction, and needs to be processed before it can become water that can be used as raw material.

[0034] Furthermore, the bottom surface of the filter tank 501 is set to be inclined, the inner wall of the filter tank 501 is detachably connected to the filter mesh plate 503, the inner bottom wall of the treatment box 502 is detachably connected to the partition mesh plate 506, the inner bottom wall of the treatment box 502 is respectively provided with a PP cotton layer 504 and an activated carbon adsorption layer 505, and the treatment box 502 is connected to the water inlet end of the steam generator 6 through a pipeline.

The PP cotton layer 504 contacts the condensed water first and can be adsorbed in advance, which can not only play a certain purification role, but also prevent the activated carbon adsorption layer 505 from being blocked by dirt, thereby maintaining the service life of the activated carbon adsorption layer 505.

[0036] Working principle: When the biomass gasification heat-charcoal cogeneration water circulation device is used, the user turns on the gasifier 1 and starts it for a period of time. The mixed gas (generally containing carbon monoxide, methane, hydrogen, etc.) produced by the gasifier 1 will enter the separation tower 3 through the air inlet pipe 9. At this time, the external collection equipment and the water spray condensation plate 401 and the separation motor 404 are started. At this time, when the high-temperature mixed gas contacts the condensed water sprayed from the water spray nozzle 402, the high-temperature water vapor contained therein will be liquefied, and other non-liquefiable gases will enter the recovery pipe 8 for collection with the help of the separation blade 405. Then this part of the condensed water will continue to flow into the filter tank 501 to filter out some impurities contained in the condensed water. After passing through the treatment box 502, it will be further purified by using the PP cotton layer 504 and the activated carbon adsorption layer 505, and finally evaporated into water vapor again in the steam generator 6 and returned to the gasifier 1 through the steam circulation pipe 7 to continue to be used as a reaction auxiliary raw material.
