Heat pump electric steam water boiler

Abstract

The invention discloses a heat pump electric steam-water boiler which comprises a liquid storage tank, a heat accumulator, a low-pressure expansion valve, a high-temperature expansion valve, a magnetic valve, a low-temperature compressor, an evaporator, a high-temperature compressor, a steam water tank and a hot water tank. The heat pump technology is adopted as the only one heat source, two-stage compression of the heat pump is utilized, the magnetic valve is selected, the low-temperature compressor is used at the initial stage, the low-temperature compressor and the high-temperature compressor are used simultaneously at the high-temperature stage, thus the energy efficiency ratio can be effectively improved. In addition, since the temperature rise of the condensing heater of the compressor of the heat pump is limited, the explosion of the heat pump due to unlimited rising of the pressure can not be caused, and the phenomenon that the existing boilers are exploded due to continuous supply of heat energy under the abnormal situation can be avoided. Moreover, since a steam-water separator is arranged internally, the water contained in the gas can be avoided. Furthermore, the heat pump electric steam-water boiler can provide clean and pollution-free steam, boiling water and hot water so that the requirement of multiple purposes can be met.

Description

Technical field [0001] The invention relates to a boiler, in particular to an energy-saving heat pump boiler. Background technique [0002] Industrial boilers are China's main thermal power equipment. The boiler industry is an eternal industry coexisting with mankind, 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 manufacturers in the country has increased by nearly one-half, and the ability to independently develop and develop new products from generation to generation has been formed. The technical performance of the products has been improved. Close to 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 certain parameters and produces high-tempe...

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

In addition, the boilers in the prior art tend to carry moisture in the steam provided, and it is easy to cause temperature and pressure fluctuations during the water replenishment process of the system, and it is easy to mix pollutants such as engine oil in the steam during the heating and heating process, thus limiting the use of the output steam
