A multi-purpose pump system

Abstract

A multi-purpose pump system, comprising a thermodynamic unit (10), a main pneumatic positive displacement pump (20), a condenser (30), a circulating pneumatic positive displacement pump (40), a pipeline and a working medium therein, wherein a fluid inlet of the thermodynamic unit (10) is connected to a fluid outlet of the circulating pneumatic positive displacement pump (40), an air outlet of the thermodynamic unit (10) is connected to an air inlet of the main pneumatic positive displacement pump (20), an air outlet of the main pneumatic positive displacement pump (20) is connected to an air inlet of the condenser (30), a fluid outlet of the condenser (30) is connected to a fluid inlet of the circulating pneumatic positive displacement pump (40), an air inlet and an air outlet of the circulating pneumatic positive displacement pump (40) are respectively connected in parallel to the air inlet and air outlet of the main pneumatic positive displacement pump (20), or are connected in series between the air outlet of the main pneumatic positive displacement pump (20) and the air inlet of the condenser (30). The multi-purpose pump system can be used not only to concentrate and absorb medium and low grade heat so as to lower the temperature of our planet, but also to elevatedly transport, heat and filter a fluid. The multi-purpose pump system may employ a steam working medium, or an organic working medium; it may absorb the heat from a single heat source, or from multiple heat sources synchronously. Moreover, the multi-purpose pump system takes fewer steps to convert energy and can be built at a low cost.

Description

technical field [0001] The invention belongs to the category of engineering thermodynamics and fluid machinery, and relates to heat energy conversion and utilization, in particular to a thermal power circulation pump system utilizing potential energy converted from medium and low-grade heat energy into liquid or gas. Background technique [0002] In the past, the number of people and animals on the earth was small, the living standard of human beings was low, farming was the mainstay, industry was underdeveloped, and energy consumption was low. The heat on the earth mainly came from solar radiation. During this period, the heat irradiated by the sun on the earth The heat absorbed, reflected and evaporated by the earth is in a stable natural dynamic equilibrium state. Nowadays (especially after the industrial revolution), the number of people and other animals (including artificial breeding) on ​​the earth has increased several times, and the energy and resources required for...
