Description

An energy-saving system that utilizes stove flue gas to circulate and heat water

technical field

The utility model relates to the technical field of kitchen equipment, in particular to an energy-saving system for circulating and heating water by flue gas from a kitchen range.

Background technique

In recent years, in order to improve air quality and reduce environmental pollution, various cities have adopted measures to eradicate environmental pollution and improve air quality, such as using low-pollution, environmentally friendly fuels (natural gas and oil). However, during the working process of the existing boilers, the flue gas produced by it is generally directly discharged to the outside through the chimney. The flue gas with high-temperature heat is directly discharged, which is not conducive to the improvement of the external environment and wastes resources, and does not make full use of the heat in the exhausted flue gas.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide an energy-saving system with simple structure, stable working effect and full and effective use of the heat of the flue gas, which utilizes the flue gas from the cooktop to circulate and heat water.

In order to achieve the above purpose, the technical solution provided by the utility model is: an energy-saving system that utilizes stove flue gas to circulate and heat water, including at least one stove body, and a water circulation heating system connected to the stove body system, the water circulation heating system includes a flue that communicates with the combustion port in the stove body, a pipe heat exchanger placed in the inner cavity of the flue, and water inlet and outlet pipes that are connected to the upper and lower ends of the pipe heat exchanger. The water pipe, the hot water recovery incubator connected to the other end of the water inlet pipe and the water outlet pipe respectively, and the circulating water pump arranged on the water inlet pipe, wherein the bottom side of the hot water recovery incubator is also provided with a A hot water switch that supplies hot water to the outside.

Preferably, the tube heat exchanger includes a cylindrical shell and a plurality of vertically arranged heat exchange tubes placed in the cylindrical shell, wherein the hot smoke in the flue passes between the plurality of heat exchange tubes The gap in the water discharges outward and heats the water in the heat exchange tube.

Further, it also includes an air combustion-supporting system communicated with the combustion port, the air combustion-supporting system includes a connecting pipe with one end communicated with the combustion port, a burner shell connected with the other end of the connecting pipe, and a burner shell placed in the burner shell fans and air heaters.

This scheme is provided with a water circulation heating system connected with the cooktop body. Specifically, the smoke generated by the cooktop body in the working process flows through the flue and exchanges heat with the pipe heat exchanger inside it, that is The water in the pipeline heat exchanger exchanges heat with the high-calorie flue gas to heat the water in the pipeline heat exchanger, and the heated water is recycled to the hot water recovery incubator under the action of the circulating water pump At the same time, the pre-heated water can continue to flow into the pipeline heat exchanger again through the circulating water pump for multiple heat exchanges with the flue gas, so as to obtain high-temperature water suitable for drinking; compared with the existing technology, this solution can be used independently The above-mentioned set of water circulation heating system is used in series with multiple stoves to make full use of the heat of the flue gas discharged by each stove in the working process, and to make full use of resources while ensuring a simple and compact structure.
