The invention discloses a self-aggregation weak-consolidation multifunctional sand control agent and application thereof, and belongs to the technical field of oil gas chemistry. The sand control agent is prepared by simply mixing 0.2-0.6 part by weight of a hydrophobic modifier, 0.6-1.2 parts by weight of a chemical modifier and 2-4 parts by weight of an organic solvent. The hydrophobic modifier is selected from one or more of the following components: methacryloyloxy silane, heptadecafluorodecyl trimethoxy silane, amino alkyl polydimethylsiloxane, octamethylcyclotetrasiloxane, poly [3-((2-aminoethyl) amino) propyl] methyl (dimethyl) siloxane, gamma-propyl trimethoxy silane and the like; the chemical modifier is a compound containing alkenyl. The sand control agent can be used for coating modification of a proppant, self-aggregation and clustering in water are realized, and solidified sand is formed through polymerization of the alkenyl-containing compound on the surface, so that the sand control effect is achieved; the sand control agent can also be directly added into fracturing fluid and permeates into a stratum to form a hydrophobic consolidation layer, so that the effect of stabilizing a rock wall surface is achieved.

The invention discloses a dinaphtho boron oxygen structure derivative and a preparation method and application thereof, and belongs to the technical field of organic light-emitting materials and semiconductors. The dinaphtho boron oxygen structure derivative has the advantages of easily available reaction raw materials, low price, conventional reaction process, high single-step reaction yield and low cost. When the prepared dinaphtho-boron-oxygen structure derivative is applied to a light-emitting layer of an OLED device as a guest light-emitting material, the roll-off efficiency of the device can be effectively reduced, the light-emitting brightness is improved, and the service life of the device is prolonged.

The invention relates to a rapid preparation method of aronia melanocarpa juice freeze-dried powder, and belongs to the field of food processing. The preparation method comprises the following steps: injecting aronia melanocarpa juice into a closed container, controlling the temperature to be 8-12 DEG C, introducing carbon dioxide gas, controlling the pressure in the container to be 0.38-0.45 MPa, reducing the temperature to-2-0 DEG C, releasing the pressure within 30 seconds to obtain aronia melanocarpa ice, then performing quick-freezing treatment to obtain aronia melanocarpa ice cubes, and finally performing vacuum freeze-drying to obtain the aronia melanocarpa juice freeze-dried powder. The method not only can effectively reduce the loss of anthocyanin of the aronia melanocarpa in the processing process, but also can greatly reduce the treatment time of vacuum freeze drying, and is a simple and rapid processing method of the aronia melanocarpa juice freeze-dried powder.

The invention discloses a drainage structure of an underground gas storage and a compressed air energy storage power station, and relates to the technical field of underground gas storage, the drainage structure is arranged on the outer wall of a lining of a gas storage cavity, the drainage structure comprises a horizontal water collecting channel arranged on the outer wall of the lining, and a first water collecting opening is formed in the horizontal water collecting channel; water flows into the horizontal water collecting channel from the first water collecting opening; the annular water collecting channel and the horizontal water collecting channel are arranged in a crossed manner and are communicated with each other; a water diversion pipe system is arranged at the bottom of the annular water collection channel, and the other end of the water diversion pipe system discharges water through a water pumping device. The underground gas storage lining solves the problems that the external water pressure of an existing underground gas storage lining is large, and a metal lining is prone to corrosion, underground seepage water can be discharged in time, and the technical effect of long-time safe, continuous and stable operation is achieved. The underground gas storage with the drainage structure can operate safely, continuously and stably for a long time, so that the compressed air energy storage power station can realize large-scale and long-time energy storage.

A low-NOx ammonia-coal stable combustion swirl burner relates to the field of clean combustion of coal with low carbon and low NOx.
