Problems solved by technology

Of course, in the CO 2 While recovering, a part of latent heat can be recovered to a certain extent, but it is quite limited
Moreover, there are high requirements for the performance of the structural components of the entire system, and the system cost is relatively high

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0025] In the present invention, the circulating working fluid in the following embodiments is CO 2 .

[0026] Such as figure 1 As shown, it is a diagram of a natural gas heating system of an embodiment provided by the present invention, and the system is divided into combustion flue gas circulation and circulating working medium circulation.

[0027] In the flue gas cycle, the flue gas with high temperature and high water vapor content produced by the combustion of natural gas entering the combustion chamber enters the heater 2 and the secondary evaporator 3 and the CO in sequence through the flue. 2 Circulating working medium for heat exchange, in which the water vapor is liquefied into condensed water, which flows out and recovered through the condensed water pipe installed on the secondary evaporator 3, and the high-temperature flue gas after...

Abstract

The invention provides a high-efficiency natural gas heating system, which mainly includes: a burner, a heater, a secondary evaporator, a working medium pump, an ejector, a cooler, a throttle valve, a primary evaporator, and a gas-liquid separator , Regenerator. While making full use of the sensible heat and latent heat of flue gas after natural gas combustion, this system also uses part of the low-grade heat energy in the ambient air to supply heat to external heat users. On the basis of the same gas consumption, the heat supply can be greatly increased and the heating cost can be reduced. It also helps to reduce the humidity of the exhaust gas, condenses the water vapor in the flue gas, and saves water resources.

Description

technical field [0001] The invention belongs to the technical field of natural gas heating, and specifically relates to a natural gas that uses the principle of heat pumps to supply heat to external heat users by utilizing the heat energy of flue gas after natural gas combustion and part of the low-grade heat energy in ambient air. Heating system. Background technique [0002] Coal-fired boiler heating is a very important heating method in my country, but as my country's environmental problems become increasingly prominent, especially after the increasingly serious smog phenomenon has attracted more and more people's attention, cleaner and more efficient heating methods are adopted appears to be particularly important. In particulate emissions, SO x emissions and NO x In terms of emissions, the natural gas heating method has significant advantages over coal-fired boiler heating, so coal-to-gas conversion has become one of the important means for my country to deal with air...
