Steam hydraulic heat pump

Abstract

The invention discloses a steam hydraulic heat pump which comprises a plurality of steam compression devices that are connected in parallel, wherein each steam compression device comprises a steam hydraulic compression chamber and a vertical pressure leg connected below the steam hydraulic compression chamber; each steam hydraulic compression chamber is divided into an upper chamber and a lower chamber by a partition wall, the upper chamber is a steam chamber, and the lower chamber is a liquid chamber; a low-grade steam inlet and a compressed steam outlet are arranged on the steam chamber, the low-grade steam inlet is connected with a low-grade steam inlet pipe through a steam inlet electromagnetic valve, a compressed steam outlet is connected with a compressed steam outlet pipe through asteam outlet electromagnetic valve; the lower part of the pressure leg is provided with a liquid feeding hole and a liquid discharging hole, the liquid feeding hole is connected with a liquid inlet pipe through a liquid inlet electromagnetic valve, the liquid inlet pipe is connected with a liquid discharging hole of the pump, a liquid feeding hole of the pump is connected with a liquid storage groove; and the liquid discharging hole is connected with a liquid discharging pipeline through a liquid discharging electromagnetic pipe, and the liquid discharging pipeline is connected with the liquid storage tank. The steam hydraulic heat pump is efficient and environmental-friendly.

Description

technical field [0001] The invention relates to a heat pump, in particular to a steam hydraulic heat pump. Background technique [0002] The familiar "pump" is a mechanical device that can increase potential energy. For example, a water pump mainly pumps water from a low level to a high level. The "heat pump" is a device that can obtain low-grade heat energy from natural air, water or soil, and provide high-grade heat energy that can be used by people through electricity. The most primitive heating method of heat pump is heat exchange, and its biggest disadvantage is the heat loss of heat exchange. [0003] The outlet temperature of ordinary heat pump units must be above 75 degrees to make sense for large heating networks. The heat-to-electricity ratio of the high-temperature heat pump unit must be above 4:1, otherwise the cost of waste heat recovery will be high. Electric energy-driven heat pumps are economically uneconomical to recycle heat energy. Although the steam t...

AI Technical Summary

Problems solved by technology

The heat-to-power ratio of the high-temperature heat pump unit must be more than 4:1, otherwise the cost of waste heat recovery will be high

Electric energy-driven heat pumps are economically uneconomical to recover circulating heat energy

Although the steam turbine heat pump can produce economic benefits in this respect, because it requires high-grade heat sources, the cost of retrofitting existing machinery is relatively high

The final exhaust steam cannot be used normally and can only be used for heating

[0004] The main evaluation method of heat pumps is the electric-to-heat ratio (which is defined as how much heat is produced by one degree of electricity). Mechanical heat pumps now mostly use fans as compression tools, and their main limitation is the vapor compression ratio. If the compression ratio is too high, the fans will not be able to operate normally.

Although the power value heat pump avoids the compression ratio problem and adopts the heat exchange method, the electric heat ratio is low
