Re-starting smoke-removing gasification furnace
When the flame gradually weakens, the cracking reaction enters the tail sound, the heat value of the cracking gas is reduced at the moment, slight smoke can appear in the flame of the combustion stove, the smoke removal gasification furnace is enlarged at the moment, the liquefied gas combustion-supporting switch of the outer stove is opened according to the situation, the smoke generated in the later period of the cracking reaction is eliminated, the process lasts for about 1 hour, and the smoke volume is reduced to almost nothing.
And closing the smoke removal gasification furnace, replacing the fire suppression cover into a smoke reduction cover, and reducing the residual trace smoke for about 1-3 hours.
The cleavage reaction is completely finished, and thereafter the next procedure is entered.
And end in
Closing all the cracking furnace air inlet pipe switches, covering the combustion stove cover, withdrawing all the fans, cleaning the field, cooling in the cracking furnace after 12 hours, lifting out the cracking barrel and pouring out the materials, weighing, bagging and ending the process.
It can be seen that the present application has the following advantages over the prior art:
the novel gas stove has the advantages of full combustion of gas and good environment-friendly effect
The pyrolysis gas generated in the material pyrolysis process has complex components, more components of tar and toxic and harmful high molecular substances, can not be directly treated by a water spraying method, and is suitable for being treated by a harmless incineration method, and the treated tail gas has no black smoke, no peculiar smell, no sewage and no generation of particulate matters. The pyrolysis gas is treated by a mixed combustion stove and is fully combusted, and the emission of tail gas can meet the requirement of environmental protection.
Do good news and carry out heat energy cyclic utilization behind gas combustion
The heat energy generated by the combustion of the pyrolysis gas can be used in cooperation with a boiler, and can also be used in a storage drying workshop for drying the materials to be treated, so that the energy is saved, and the heat energy is recycled.
The gasification decomposition of the flue gas is adopted, so that the environmental protection cost is reduced
The pyrolysis flue gas has lower calorific value and poor direct combustion effect, the fuel gas generated by the gasification furnace is used for assisting in combustion to decompose harmful components in the flue gas, and the agriculture and forestry wood waste and the sorted domestic garbage are added into the gasification furnace, so that the environmental protection requirement can be met, and the operation cost is reduced.
Improvement of aging through cracking in internal heating mode
The cracking furnace adopts a controllable internal heating mode to produce carbon, which is beneficial to improving the heat efficiency. The controllable internal heating cracking mode can raise the temperature in the furnace to more than 350 ℃ within 1.5 hours, thus greatly improving the aging efficiency, because the traditional cracking furnace adopts an external heating mode, namely, the biomass in the cracking furnace continuously absorbs heat through external heating, when the temperature reaches more than 350-.
Production cost is reduced by adding low-value garbage into bottom layer of cracking furnace
The cracking in the internal heating mode is carried out, the material loss is more, so that when materials are added, low-value agricultural and forestry wood wastes with the height of about 300mm are added to the bottom layer, and the cracking treatment cost is saved. The system runs for about 8 hours in total, so that the materials are basically decomposed and all become inorganic matters such as carbon, ash and the like.
Sixthly, carbide is added to the top layer of the cracking furnace, so that processing time is saved
In the cracking process, complete equilibrium is difficult to achieve, particularly, the material with the uppermost part being about 100mm high is difficult to crack due to low temperature, so that the time for cracking treatment is prolonged for the good cracking of the material, and the timeliness is poor. Therefore, when materials are added, the carbide with the height of 100-200mm is added to the top layer, so that the cracking quality can be improved. The uppermost material in the cracking barrel is in a semi-carbonized shape because the temperature is lower and the material is not completely cracked, and if the uppermost is covered with a layer of prepared carbon with the thickness of 100-200mm, the material on the uppermost is completely carbonized.
The above description is only for the purpose of illustrating the preferred embodiments of the present application and is not to be construed as limiting the present application, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present application should be included in the scope of the present application.
