The present invention provides modular devices and systems for infusing gas into a liquid and methods of manufacture and use thereof. In accordance with an embodiment, a modular device for infusing gas into a liquid is provided. The modular device comprises a plurality of microporous hollow fibers, and a cap covering open ends of the microporous hollow fibers. The cap is configured to receive a gas into an opening and to deliver the gas into the open ends of the microporous hollow fibers. The cap is further configured to removably mount the modular device to a fixture. A system for infusing gas into a liquid may include one or more of the modular gas infusion devices configured to be removably mounted to a fixture such that the microporous hollow fibers are within a hollow cavity. The hollow cavity includes a first opening configured to receive a liquid and a second opening configured to discharge the liquid infused with a gas. Because the system is modular, it is economical to manufacture, scale to different application requirements and to maintain.

A gas injection module and an active gas injection system are provided. The gas injection module includes a device body, the internal of which has a delivering cavity and an annular gas-flow generation cavity. One end of the device body has a gas input portion, and another end thereof has a gas output portion. One side of the device body is configured to extend outward to form a gas guiding portion. The annular gas flow generation cavity includes a side connecting portion and a nozzle portion in spatial communication with each other. The side connecting portion is connected to the gas guiding portion. The nozzle portion is connected to the delivering cavity. The nozzle portion is configured for generating a pushing gas-flow in a pre-determined path toward the delivering cavity. A pre-determined angle between 0-89 degrees is between the pre-determined path and central axis of the device body.

The present application discloses a gas cooling apparatus and a heat furnace. The gas cooling apparatus comprises a pipeline structure. The pipeline structure defines a gas flow channel and a liquid channel; the gas flow channel is used for circulating a high-temperature gas; and the liquid channel is located outside the gas flow channel and is provided with a liquid spraying part communicated with the gas flow channel. The pipeline structure is further provided with a gas spraying part communicated with the gas flow channel; and a liquid sprayed from the liquid spraying part can be atomized under the action of the high-temperature gas in the gas flow channel and the high-pressure gas sprayed from the gas spraying part. The gas cooling apparatus has the advantages of simple structure, convenient use, rapid cooling rate for a high-temperature gas, and less use of a cooling liquid.
