  • Patent number: 11988333
    Abstract: A bladder-type pressure tank includes an outer shell, a bladder, a nozzle, and an elbow pipe. The outer shell includes a liner and a glass-fiber layer covering the outer surface of the liner. The liner includes polyethylene (PE). The liner further includes a chamber, a first opening, and a second opening. The bladder is disposed in the chamber. In an inflated state of the bladder, a gap is formed between the inflated bladder and the inner surface of the liner. The bladder includes polyurethane (PU). The nozzle is integrated with the bladder, and is disposed in the first opening and seals the first opening. The elbow pipe includes a first end and a second end. The first end of the elbow pipe is disposed in the second opening and communicates with the chamber; and the second end of the elbow pipe is configured to connect to a pipeline.

  • Patent number: 11976891
    Abstract: The present invention relates to the field of fluid heat transfer, and discloses a heat transfer enhancement pipe as well as a cracking furnace and an atmospheric and vacuum heating furnace including the same. The heat transfer enhancement pipe (1) includes a pipe body (10) of tubular shape having an inlet (100) for entering of a fluid and an outlet (101) for said fluid to flow out; internal wall of the pipe body (10) is provided with a fin (11) protruding towards interior of the pipe body (10), the fin (11) spirally extends in an axial direction of the pipe body (10), wherein a height of the fin (11) gradually increases from one end in at least a part extension of the fin. The heat transfer enhancement pipe can reduce thermal stress of itself, thereby increasing service life of the heat transfer enhancement pipe.

  • Publication number: 20240100015
    Abstract: The present disclosure provides an arctigenin liquid nano-preparation and a preparation method thereof, and relates to the technical field of pharmaceutical preparation. In the present disclosure, arctigenin is prepared into a liquid nano-preparation, having advantages of distribution of a droplet diameter on nanoscale, significantly increased specific surface area, rapid absorption, and high bioavailability. Meanwhile, nano-preparation entered the body can be captured by wandering leucocytes, and a medicament is delivered to inflammatory lesions through chemiotaxis, thereby conferring a targeted drug delivery feature on the arctigenin and making a therapy more targeted. Moreover, in the present disclosure, the arctigenin is dissolved in an oil phase, and the oil phase is dissolved in water by emulsification to further make the arctigenin dissolve in the water and increase water solubility of the arctigenin.

  • Publication number: 20240102111
    Abstract: The present invention relates to a molecular marker, a specific primer pair, and an identification method of the high-quality Ganoderma lucidum strain HMGIM-M624. The high-quality Ganoderma lucidum strain HMGIM-M624 was preserved in Guangdong Microbial Culture Collection Center (address: 5th Floor, No. 59 Building of No. 100 Yard, Mid. Xianlie Road, Guangzhou City) with the preservation number of GDMCC No: 60889 on Nov. 7, 2019. The molecular marker is an InDel molecular marker. The high-quality Ganoderma lucidum strain HMGIM-M624 has a base deletion of CATGCTGTA at the 246451th-246460th site of the chromosome sca34. The present invention provides reagents for detecting the molecular marker of the high-quality Ganoderma lucidum strain HMGIM-M624. The reagents can distinguish the high-quality Ganoderma lucidum strain HMGIM-M624 from the other 11 G. lucidum strains for commercial cultivation, thus specifically identifying the high-quality Ganoderma lucidum strain HMGIM-M624.

  • Patent number: 9120089
    Abstract: An inorganic/organic composite support includes an inert inorganic material, a complex compound composed of a polylol and a magnesium halide, and an organic polymer containing a polar functional group. Said complex compound loaded with the organic polymer is deposited on the inert inorganic material. When the inorganic/organic composite support used as a polyolefin catalyst carrier is applied to ethene or propylene polymerization, the fusion-flow ratio of the obtained polymerisate is remarkably increased and its processing performance is improved. When the catalyst is applied to ethene polymerization, the fusion-flow ratio of the polymerisate can be adjusted by changing the content of hydrogen. When the catalyst is applied to ethene or propylene polymerization, the catalyst activity is high.
