Multipurpose pump system

Abstract

The invention belongs to the field of engineering thermodynamics and fluid machinery, and discloses a multipurpose pump system. The multipurpose pump system is characterized by being composed of a heat power unit, a main pneumatic volumetric pump, a condenser, a circulation pneumatic volumetric pump, a pipeline and a working medium inside the pipeline. A flow inlet of the heat power unit is connected with a flow outlet of the circulation pneumatic volumetric pump. An air outlet of the heat power unit is connected with an air inlet of the main pneumatic volumetric pump. An air outlet of the main pneumatic volumetric pump is connected with an air inlet of the condenser. A flow outlet of the condenser is connected with a flow inlet of the circulation pneumatic volumetric pump. An air inlet and an air outlet of the circulation pneumatic volumetric pump are connected with an air inlet and an air outlet of the main pneumatic volumetric pump in parallel or connected between the air outlet of the main pneumatic volumetric pump and the air inlet of the condenser in series. The multipurpose pump system can collect and absorb middle-low-grade heat to cool the globe, and can also be used for lifting conveying, heating and filtering fluid; a water vapor working medium or an organic working medium can be adopted, heat of a single heat source can be absorbed, and heat of multiple heat sources can be absorbed synchronously; the heat conversion process is simplified, and the investment is low.

Description

Technical field [0001] The present invention is a thermal conversion and utilization of thermodynamics and fluid machinery, which involves the thermal cycle pump system that uses low -quality thermal energy to convert to liquid or gas. Background technique [0002] In the past, the number of people and animals on the earth was small, the level of human living was low, the farming -oriented, the industry was underdeveloped, and the energy consumption was small. The calories on the earth mainly came from the solar radiation.The calories of the Earth's absorption, reflection, and water evaporation are in a stable natural dynamic balance.Today (especially after the industrial revolution), the number of people and other animals (including artificial breeding) on the planet increases several times. The energy and resources required for human production and living activities have also increased. Some information shows about 85%~90%of the energy sources are converted into thermal energy ...
