23 results about "Thermosiphon" patented technology

Thermosiphon (or thermosyphon) is a method of passive heat exchange, based on natural convection, which circulates a fluid without the necessity of a mechanical pump. Thermosiphoning is used for circulation of liquids and volatile gases in heating and cooling applications such as heat pumps, water heaters, boilers and furnaces. Thermosiphoning also occurs across air temperature gradients such as those utilized in a wood fire chimney or solar chimney.

System for online handling of reboiler line siphon failure

ActiveCN224442196UFluid phaseReboiler
This invention provides a system for online treatment of siphon failure in the reboiler pipeline of a distillation column, relating to the technical field of thermosiphon in distillation systems. The system includes a liquid phase pipeline in the reboiler, on which a drain valve is installed, and a nitrogen pipeline is connected to the drain valve. By installing a drain valve on the liquid phase pipeline of the reboiler and connecting it to a nitrogen pipeline, the system uses nitrogen to briefly purge the liquid phase pipeline, blowing away metal powder and silicate impurities that clog the reboiler's liquid phase pipeline into the reboiler pump's liquid phase pipeline. These impurities are then filtered and carried away by the reboiler pump's inlet filter, preventing pipeline blockage, improving the reboiler's heat exchange efficiency, and thus improving the problems of reboiler siphon failure and methanol waste. This invention can treat the siphon failure problem of the methanol recovery column's reboiler pipeline online without shutting down the system, avoiding the cost losses caused by shutdown.

A loop thermosiphon device

ActiveCN116182606BWorking fluidEvaporation heat transfer
This invention discloses a thermosiphon loop device. The evaporator consists of four parts: a liquid chamber, a vapor chamber, a microgroove structure, and a filter screen. The microgroove structure significantly increases the number of vaporization nuclei, enhancing boiling heat transfer. Above the microgroove structure, a hemispherical filter screen is designed to drastically reduce the amount of liquid carried into the vapor chamber, thereby enhancing gas-liquid separation within the evaporator. This gas-liquid separation allows the working fluid to have a higher dryness near the evaporation section outlet, significantly increasing the density difference and pressure driving force between the vapor and liquid phases inside the thermosiphon loop, and improving the heat transfer limit. Furthermore, a heat insulation device is installed in the condensate return pipe at the bottom of the evaporation section to suppress backflow caused by the growth and expansion of boiling bubbles, effectively reducing heat leakage at the bottom of the evaporation section. This invention achieves gas-liquid separation within the evaporator and reduces heat leakage at the bottom, thereby improving the heat transfer performance of the thermosiphon loop and making it suitable for high-power heat dissipation requirements.

This invention discloses an air dehumidification and cooling system and method with thermosiphon water recovery, a cooling tower, and a power plant. The system includes a tower body, a dehumidifier, a dehumidifying liquid regenerator, and a waste heat flue gas recovery unit. The dehumidifier pre-treats the high-humidity air entering the tower to enhance its cooling potential.

When the generated humid and hot air flows through the thermosiphon array, the water vapor in it is condensed and recovered to a water collection tank. The dehumidified dilute dehumidifying liquid is sent to the regenerator, where it is regenerated by heating with waste heat flue gas from the power plant and then recycled. Through the closed-loop collaborative design of "air dehumidification pre-treatment - efficient evaporative cooling of circulating water - condensation and recovery of humid air moisture by thermosiphon - waste heat utilization to regenerate dehumidifying liquid", the system solves the dual problems of low efficiency and high water consumption of cooling towers in humid and hot environments, simultaneously improving cooling efficiency and water resource recovery rate, and achieving synergistic effects of energy saving and water saving.
