The application discloses a high-efficiency carbon fixation microalgae breeding device, and relates to the technical field of carbon fixation microalgae breeding.The device comprises an elongated pool, a partition plate is arranged at the middle position of the elongated pool, so that a loop-shaped channel in the shape of a long strip is formed in the elongated pool, bottom plates are arranged in the two parallel straight channels of the loop-shaped channel, the upper surfaces of the bottom plates are arranged in an inclined manner, and the inclined directions of the two bottom plates are opposite.Two liquid lifting mechanisms are arranged at the high end positions of the two bottom plates respectively, and are used for lifting the algal liquid in the loop-shaped channel to the high end of the bottom plate, so that the algal liquid flows downward along the upper surface of the bottom plate automatically.Two groups of disturbance mechanisms are arranged on the upper surfaces of the two bottom plates.The algal liquid is driven to form a turbulent state by the bidirectional inclined bottom plates, the liquid lifting mechanism and the disturbance mechanism, the problems of surface light inhibition and bottom dark area are reduced, and the light energy utilization efficiency of the microalgae is improved significantly.

The present invention discloses an ozone catalytic oxidation system and process for multiphase extract treatment, and relates to the technical field of environmental wastewater enhanced treatment. The system comprises an outer reaction tube and an inner reaction tube, and the outer periphery of the bottom and the middle of the inner reaction tube are respectively sleeved with a first catalytic component and a second catalytic component, and the catalyst is a copper-cerium bimetallic ceramsite catalyst. The process comprises the following steps: S1, liquid inlet; S2, turbulent catalysis; S3, reflux; S4, backwashing. The present invention can increase the disturbance of water flow by establishing a water outlet circulation, so that the inner and outer reaction tubes present a good turbulent state, and through the countercurrent contact of ozone with the multiphase extract in the inner water inlet pipe and the outer reaction tube and the mixed contact with the multiphase extract in the two-layer catalyst assembly, the contact effect of the ozone catalyst and the ozone gas is increased, and the contact time between the wastewater and the ozonated air is prolonged, thereby improving the solubility of ozone in water.

The invention discloses a chilled beam air conditioning system terminal which comprises a static pressure box, at least two heat exchange boxes, a plurality of rows of nozzles and at least two heat exchangers, and an air inlet is formed in the static pressure box; the heat exchange boxes are arranged under the static pressure box side by side at intervals, the upper surfaces of the heat exchange boxes are open, and a plurality of air inlet holes are formed in the bottom surfaces of the heat exchange boxes. Each row of nozzles are arranged between the static pressure box and each heat exchange box, the inlet ends of the nozzles are communicated with the interior of the static pressure box, and the outlet ends of the nozzles face downwards; each heat exchanger is arranged in the corresponding heat exchange box. The heat exchanger has the advantages that due to the fact that all the water inlets are formed in all the bent sections of the S-shaped bent pipe, the water flow direction of chilled water entering the heat exchange pipe is changed, two water flows converge into one water flow, water flow impact occurs, a fluid flow boundary layer is damaged, the fluid turbulent flow state is intensified, and the heat exchange effect is improved. Therefore, the heat exchange effect of the chilled water and the indoor air is enhanced.

A plurality of independent cooling spaces are formed between a partition condensation plate and an outer sleeve, and meanwhile, a partition condensation device is continuously rotated, so that high-temperature and high-pressure gas can enter the communicated cooling spaces from the bottom through a gas inlet pipe, and upwards flows to be in contact with staggered condensation pipes for heat exchange; as the position of the cooling space is continuously changed, the content of high-temperature and high-pressure air needing to be cooled in the single cooling space is limited, and the cooling liquid in the condensation pipe continuously flows and circulates, so that the high-temperature and high-pressure air in the single cooling space can obtain long-time and high-efficiency heat exchange; and when the cooling space is communicated with the water drainage pipe, the water on the water accumulation seat in the cooling space is drained.

According to the indoor swimming pool ventilation device, by arranging an exchange pipeline, exhausted indoor air can enter an exchange chamber and then pass through a heat exchange plate, introduced outdoor air can also enter the heat exchange plate, in hot days, indoor moist cold air passes through the heat exchange plate and exchanges heat with outdoor hot air in the heat exchange plate, and therefore the indoor air can be ventilated; in cold days, the indoor wet hot air passes through the heat exchange plate and exchanges heat with outdoor cold air in the heat exchange plate, so that the hot air is heated and then discharged into the room, and in the process, liquid generated on the heat exchange plate slides downwards, and a water curtain is formed at the bottom end of the heat exchange plate; the outside air is wetted when passing through the water curtain, so that the temperature difference between the outside air introduced into a room and the indoor air is reduced, and the problem that the humidity of the indoor air is too low due to the fact that a large amount of dry air is exhausted into the room is solved.
