The upper end of the drive shaft is connected with the driving motor. The lower end of the drive shaft is connected with the de-icer. The de-icer comprises a support and de-icing blades. The de-icing blades are vertically arranged on the lower surface of the support. The support is provided with 1-3 arms. The lower ends of the de-icing blades extend into annular flow channels of the concentric annular spray-nozzle. The number of the de-icing blades on a single support arm is the same with that of the annular flow channels of the concentric annular spray-nozzle. An ice-making solution is provided in the generator body. With the generator provided by the invention, ice blockage can be effectively prevented, and system ice-making solution leakage can be reduced. The ice slurry is stirred, such that a heat exchange effect is reinforced. Therefore, the stable and highly efficient operation of the ice slurry preparation system is promoted.

Novel fluid damping device capable of coping with pressure jump
The invention discloses a novel fluid damping device capable of coping with pressure jump. The novel fluid damping device comprises a hollow box body and a damping part, wherein the hollow box body isvertically placed, is in the shape of an inverted circular truncated cone, is coaxially provided with a pipeline outlet and a pipeline inlet at upper and lower ends as well as a connecting part for connecting a gas outlet pipeline to a gas inlet pipeline; the damping part is freely placed in the box body; when the damping part rises to be in contact with the pipeline outlet, close fit degree between the upper end of the damping part and the pipeline outlet is 30%-40%; and when the damping part drops to be in contact with the pipeline inlet, close fit degree between the lower end of the damping part and the pipeline inlet is 95%-100%. The novel fluid damping device is simple in structure, can retard pressure jump, effectively prevents backflow, is high in sensitivity, balances a device temperature, prevents an ice blockage phenomenon generated due to the fact that the temperature is too low, can reduce operation cost of enterprises, and improves benefits.

Condensation method oil gas recovery method and device
ActiveCN114437753AReduce dosageContinuous operationLiquid hydrocarbon mixture recoveryWater storageWater storage tank
The invention discloses a condensation method oil gas recovery method and a recovery device. After being heated, oil gas to be treated sequentially flows through the deep cooler A, the shallow cooler A, the pre-condenser, the shallow cooler B and the deep cooler B; the heated to-be-treated oil gas is adopted to carry water generated during defrosting in the heat exchanger to the water storage tank, and defrosting liquid and condensed liquid enter the oil storage tank or the water storage tank in the gas flowing direction. Oil gas enters the deep freezer in a switching mode, continuous operation of the oil gas recycling process through a condensation method is achieved, hot refrigerant compressed gas is used for heating waste gas to be treated, the heated waste gas to be treated serves as a defrosting medium, and frosting cooling capacity is recycled. The method provided by the invention can effectively reduce the cooling water consumption and device energy consumption of the condensation method oil gas recovery device.
