Heat pump electric steam boiler

Abstract

The invention discloses a heat pump electric steam boiler. The heat pump electric steam boiler comprises a heat exchange evaporator, a pressure container a and a pressure container b. As the heat pump technology is adopted in the heat pump electric steam boiler to serve as a sole heat source, energy in other media can be used, the energy efficiency ratio of the heat pump electric steam boiler is larger than the energy efficiency ratio of other boilers, large-proportion energy saving is achieved, and the larger energy saving, emission reduction and efficiency increase effect is obtained. In addition, as the temperature rise of a compressor condenser of a heat pump is limited, and continuous work will be stopped after the temperature reaches a certain ceiling temperature, explosion caused by unlimited rise cannot be caused, and explosion caused by continuous supply of the heat energy under the abnormal conditions of a prior boiler is avoided. Then steam separator is arranged in the heat pump electric steam boiler, so that the problem that water is contained in gas is solved. Finally, the lower temperature and the high temperature are separated, buffer space is provided, water replenishing is carried out in a lower temperature area, and therefore the pressure and temperature fluctuations can be avoided in the water replenishing process.

Description

technical field [0001] The invention relates to a heat pump steam boiler, in particular to an energy-saving heat pump electric steam boiler. Background technique [0002] Industrial boilers are the main thermal power equipment in China. The boiler industry is an eternal industry that coexists with human beings, especially in China, which is still a continuously developing industry. After the 1980s, China's economy has undergone rapid changes, the boiler industry has become more prominent, the number of boiler manufacturing enterprises in the country has increased by nearly one-half, and the ability to independently develop and develop new products generation after generation has been formed. approaching the level of developed countries. Boiler is an indispensable commodity in the era of economic development. How it will develop in the future is worth studying. [0003] A steam boiler refers to an industrial boiler that heats water to a certain parameter and produces high-t...

Problems solved by technology

Therefore, the energy efficiency ratio of this combined heating is above 1.5, but its disadvantage is that the semiconductor heat pump is expensive and complicated to use, and the driving power must be DC.

However, the power of DC power supply equipment is small, so its cost is high, the technology is complicated, and it is difficult to output high power. There are certain problems in the implementation process.

[0005] In summary, the traditional electric, oil, and gas steam boilers on the market have a common disadvantage that the energy efficiency ratio is 1, it is impossible to use environmental energy, and cannot effectively use various waste water, factory sewage, environmental hot water, and solar water heaters in the environment. The hot water in the sewage, through the sewage source heat exchanger, brings the heat energy contained in the urban sewage of the building, and brings the heat energy in the soil, and the heat energy contained in the water of rivers and lakes through groundwater and ground wells.

However, the hybrid boiler using heat pump and traditional electric, oil, and gas heating has disadvantages such as low energy efficiency ratio, high cost, complicated use, and loud noise.

Moreover, the boilers in the prior art provide heat to heat water into steam. The heating method is simple and direct, and it is easy to make the internal pressure of the boiler continue to rise. The operator poses a great threat
