Heating device capable of realizing rapid heating through liquid and steam vacuum circulation

Abstract

The invention relates to a heating device capable of realizing rapid heating through liquid and steam vacuum circulation. The heating device comprises a steam boiler, a steam outlet pipe, a liquid return pipe and a heat exchange mechanism, wherein an electric heating panel is installed in the steam boiler; the steam outlet pipe is installed at the top end of the steam boiler, and the liquid returnpipe is installed at the lower end of the steam boiler; and the electric heating panel heats liquid heat exchange media in the steam boiler, the liquid heat exchange media boil and produce steam, thesteam enters an inner cavity of a steam heat exchange core body of the heat exchange mechanism under the vacuum condition, the steam transfers heat to the pipe wall of the heat exchange core body andconducts the heat to heat exchange fins, indoor cold air makes contact with the heat exchange fins and is constantly heated, after heat exchange, the hot steam forms condensed water and reaches a collecting pipe through an inclined flat heat exchange pipe, finally the hot steam circularly returns back into the steam boiler through the liquid return pipe, the heat of the electric heating panel iscircularly reciprocated for forced convection and rapidly transferred into indoor air, the purpose of indoor heating is achieved, greening and environment protection are achieved, the environment is protected, and the heating device is very suitable for home heating.

Description

technical field [0001] The invention relates to the field of heating, in particular to a heating device capable of rapid heating by liquid and steam vacuum circulation. Background technique [0002] At present, most of the indoor heating facilities used in international and domestic household hot water demand and heating and cooling demand use electric heaters, natural gas wall-hung boilers for heating, and geothermal heating (hot water , heating cable), central heating and air conditioning electric heating (water, oil, steam) heating, oil tincture heating, air energy and geothermal energy heat pump heating, solar hot water + heat pump (or wall-mounted boiler) heating, mobile heating and other heating modes To sum up the characteristics of these heating modes, they are mainly divided into the following categories. The first type is the mode with wall-hung boilers and micro-boilers as heat sources: this type of natural convection heating mode in which hot water is provided by...

Problems solved by technology

The development and utilization of new energy solar energy and heat pumps, as well as the efficient use of traditional resources, and the mature promotion of various energy-saving technologies and energy-saving products have all added impetus to the development of the heating industry; The underground pipelines connect thousands of households, which also poses a huge safety hazard; because the energy efficiency of small-scale hot water boilers cannot be compared with large-scale gas-fired boilers, and the maintenance costs of underground natural gas pipelines will rise sharply after a period of time, this Will lead to a gradual increase in the cost of residential natural gas
