This utility model discloses a nozzle device for a centrifuge containing blast furnace molten slag, including a centrifuge roller, a rubber ring, multiple nozzles, and an air ring. The rubber ring is configured to be extended to cover the cotton-like area under the centrifuge roller. An adjustable nozzle angle mechanism is provided between the rubber ring and the air ring. This mechanism includes multiple adjustable supports, one end of which is fixed to the rubber ring, and the other end is connected to the nozzle. This utility model, by extending the rubber ring, increasing the number of nozzles to at least 12, and combining the adjustable nozzle angle mechanism with an anti-clogging device, clears the blind spots of glue coverage in the cotton-like area under the centrifuge roller, reducing the waste cotton rate. Simultaneously, combined with the air ring groove interlocking structure and auxiliary air duct system, it improves the uniformity of cotton dispersion, reduces nozzle maintenance frequency, increases daily output per line, saves glue costs and waste disposal fees, improves the stability of continuous production line operation and resource utilization efficiency, and meets the requirements of efficient utilization and high-cleanliness production of blast furnace molten slag in the metallurgical industry.

This invention belongs to the field of oil and gas well reservoir stimulation technology, specifically relating to an emulsion for fracturing fluid suitable for bio-colloid flowback fluids and its preparation method. The fracturing fluid emulsion for bio-colloid flowback fluids, by weight, comprises the following raw material components: 80-100 parts acrylamide, 20-30 parts glycyl alanine, 5-10 parts cyclomethylsiloxane oil-in-water dispersant, 10-20 parts 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide, 10-20 parts hydroxyethyl methacrylate, 15-30 parts 2-acrylamido-2-methylpropanesulfonic acid, 60-80 parts white oil, 5-10 parts emulsifier, 5-10 parts initiator, and 10-15 parts water. This fracturing fluid emulsion significantly increases the solids content while also improving the performance of the fracturing fluid product, thus exhibiting excellent thickening properties even when formulated with bio-colloid flowback fluids.

The utility model discloses a municipal sludge and sewer sludge co-processing system, which comprises a sewer sludge cleaning and screening device, a mixed sludge drying device, a mixed dry sludge processing device and a condensing device, the mixed sludge drying device is used for drying a sludge mixture formed by municipal sludge and impurity-removed sewer sludge, the sludge mixture is dried by the mixed sludge drying device to generate dry sludge and dry tail gas, the mixed dry sludge treatment device is used for treating the dry sludge, and the condensing device is used for condensing the dry tail gas.
