Hollow fiber membrane liquid dehumidifying device driven by gas heat pump

Abstract

The invention discloses a hollow fiber membrane liquid dehumidifying device driven by a gas heat pump. The hollow fiber membrane liquid dehumidifying device comprises an air inlet system, an exhaust system, a gas heat pump device, a dehumidifying solution circulating system, a gas engine waste heat recovery device, wherein the air inlet system is used for conveying air into a room, and the exhaust system is used for exhausting the air out of the room. According to the hollow fiber membrane liquid dehumidifying device driven by the gas heat pump, the gas heat pump is adopted for providing the required cooling capacity before air dehumidifying and the required heat before solution regeneration, the steam partial pressure difference between the two sides of a membrane assembly is increased, and good mass transfer efficiency is achieved; at the same time, the gas engine waste heat recovery device and a solution heat-regenerating device are adopted, so that energy consumption is reduced, and the energy utilization rate is increased; the gas heat pump has a good partial load characteristic so that gas combustion season peaks and valleys can be effectively balanced, the peak shaving problem of natural gas reserves is solved, the gas pipe network utilization rate is further increased, and the comprehensive gas supplying cost is further reduced; meanwhile, relieving of the tense power supply situation caused by summer power utilization is facilitated; natural gas is also a clean and efficient energy source, harmful emissions are basically avoided, and it is conducive to environmental protection.

Description

technical field [0001] The invention relates to an air dehumidification system and a process thereof, in particular to a hollow fiber membrane liquid dehumidification device driven by a gas heat pump. Background technique [0002] According to statistics, people spend 70% to 90% of their lives indoors, so it is very important to ensure the comfort of the human body by adjusting the indoor environment. Adjusting the indoor environment is mainly achieved by controlling the two parameters of temperature and humidity in the room. Humidity, like temperature, also plays an important role in human comfort and health. The hot and humid weather hinders the evaporation of human sweat, inhibits the regulation of human body perspiration and heat dissipation, and makes people feel hot; the humid environment is easy to make people suffer from rheumatism, asthma, allergic rhinitis and other diseases; too high humidity will also aggravate indoor water solubility. The release of pollutants...

Problems solved by technology

However, the increase in component pressure can easily cause membrane rupture and pollute the air quality. At the same time, compressing air requires a lot of energy. The energy utilization rate of the system is not high, and it will increase the load on the power grid during the peak period of electricity consumption.

The Chinese invention patent with the notification number CN105258250A proposes to use solar energy to regenerate the solution. Although solar energy is a clean and renewable energy source, it is affected by weather conditions, which limits its large-scale engineering application
