The invention provides a garbage cracking furnace system and belongs to the technical field of a garbage cracking furnace.The system solves the problems that an existing garbage cracking furnace causes environment pollution, and the cracking effect is not good.The garbage cracking furnace system comprises a garbage smashing and dehydrating mechanism, a garbage pre-airing mechanism and a garbage cracking furnace which are sequentially connected.A high-temperature waste gas outlet of the garbage cracking furnace is connected with a hot air inlet of the garbage pre-airing mechanism through a pipeline, and accordingly pre-airing treatment is conducted on garbage by means of high-temperature waste gas.A cold air outlet of the garbage pre-airing mechanism is connected to a purification condenser, and a purified air outlet of the purification condenser is connected to the garbage cracking furnace so that the purified air can return into the garbage cracking furnace for use.The system has the advantages of being capable of avoiding environment pollution, according with the concept of environment friendliness, improving work efficiency of the garbage cracking furnace, being high in carbon recycling efficiency and the like.

The invention relates to the field of biological energy sources, in particular to a multistage liquefaction process of biomass. Slurry for the biological energy sources is prepared by the steps of sequentially carrying out drying, primary crushing, compressing and secondary crushing on straw, and then mixing the product with a first catalyst to obtain a mixture; adding the obtained mixture into anoil product, and grinding to prepare slurry with a straw concentration of 30-60wt%. According to the multistage liquefaction process of the biomass, a treatment process of first compressing and thensecondary crushing is carried out on the straw for the first time, and the loose straw is sequentially subjected to stages such as rearrangement, mechanical denaturation and shaping rheology by compressing the biomass, so that the volume of the straw is greatly reduced, the porosity of the straw is further reduced, the density and specific gravity of the straw are increased, the straw is more easily dispersed in the oil product, the content of the straw in the oil product is increased, and the concentration of a reaction material is increased; the multistage liquefaction process increases thebiomass conveying capacity of a pump within unit time, guarantees the smooth operation and transportation of the pump, and increases the conversion rate of the biomass.

The invention relates to the field of biological energy sources, in particular to a one-pot liquefaction process of biomass. The process comprises the following steps: firstly, preparing slurry containing a catalyst, a vulcanizing agent and biomass, and then introducing hydrogen into the slurry for carrying out a reaction. The slurry is prepared by the steps of sequentially carrying out drying, primary crushing, compressing and secondary crushing on plant oil residue, and then mixing the product with the catalyst and the vulcanizing agent to obtain a mixture; adding the obtained mixture into an oil product, and grinding to prepare slurry, wherein the prepared slurry is biomass slurry with a plant oil residue concentration of 50-65wt%. According to the one-pot liquefaction process of the biomass, a treatment process of first compressing and then secondary crushing is carried out on the plant oil residue for the first time, so that the volume of the plant oil residue is greatly reduced,the plant oil residue is more easily dispersed in the oil product, the content of the plant oil residue in the oil product is increased, and the concentration of a reaction material is increased; theone-pot liquefaction process increases the biomass conveying capacity of a pump within unit time, and guarantees the smooth operation and transportation of the pump.

The invention discloses a super-high seam coal face hydraulic fracturing coal mining method. The super-high seam coal face hydraulic fracturing coal mining method includes the following steps of drilling a row of hydraulic fracturing holes in a coal body above a coal face in the length direction of the coal face, wherein the hydraulic fracturing holes include shallow holes and deep holes in a staggered mode; installing a water injecting and hole sealing device at the bottom of each hydraulic fracturing hole, and performing high-pressure water injecting on each hydraulic fracturing hole so thatthe coal body above the coal face can be crushed and caved. The hydraulic fracturing holes in the super-high seam coal face hydraulic fracturing coal mining method are distributed in the high-low staggered mode, hydraulic fracturing can be carried out on different depth layers, top coal fracturing is sufficient, hydraulic fracturing blind areas are avoided, and the top coal caving lumpiness is reduced; construction is simple and convenient when holes are vertically formed in the coal face, the water injecting and hole sealing devices in the drilled holes are not prone to blockage, and recovery is easy under the effect of gravity.

The invention relates to the technical field of clean energy sources, and particularly provides a multi-stage liquefying technology of coal and biomass. The multi-stage liquefying technology comprisesthe following steps of firstly, compressing the coal and biomass raw materials, crushing, and crushing again; preparing into a slurry, so as to successfully obtain biomass water coal slurry which hashigh solid content and can be stably conveyed by a pump. The multi-stage liquefying technology of coal and biomass has the advantages that the coal and the biomass are hydrolyzed at high pressure andhigh temperature, and the hydrolyzed product is sequentially subject to primary cracking, hydrogenation reaction, deep cracking and hydrogenation reaction under the actions of critical hydrogen, a first catalyst and a second catalyst, so as to convert the coal and biomass into bio-oil and refine the bio-oil; the conversion rate of biomass and coal can reach 97 to 99%, the yield rate of bio-oil can reach 70 to 80%, and the amount of residues is lower than 3%.
