Description

Heating furnace waste heat water heater

technical field

The utility model relates to a water heater, in particular to a waste heat water heater which utilizes the waste heat of a civil heating furnace to heat hot water.

Background technique

Small civil heating stoves are a kind of clean and safe winter heating equipment widely used by people. However, there is a common defect in commercially available heating stoves. They fail to make full use of thermal efficiency, resulting in a lot of energy waste. The black smoke is too thick and emits a large amount of hot air, polluting the air and the environment.

Utility model content

The purpose of the utility model is to solve the problems of insufficient utilization of thermal efficiency and environmental pollution caused by flue gas in current heating furnaces, and provide a heating furnace waste heat water heater for heating hot water by using the waste heat of civil heating furnaces.

The purpose of this utility model is achieved by the following technical solutions, which include a shell water jacket and heat exchange pipes, a plurality of heat exchange pipes are arranged in the shell water jacket, each heat exchange pipe is connected to the shell water The sleeves are connected, and the lower part of the shell water jacket is respectively provided with a cold water inlet and a smoke inlet, and the upper part is respectively provided with a hot water outlet and a smoke outlet. A smoke exhaust adjustment door can be added at the smoke outlet of the shell water jacket, and the smoke exhaust adjustment door is connected with the smoke exhaust adjustment handle outside the smoke outlet; multiple ash cleaning boards can be added in the shell water jacket, and each ash cleaning board They are all inserted on the heat exchange exhaust pipe, and are respectively connected with the handle of the ash removal rod outside the water jacket of the shell through the pull rod; pull the handle of the ash removal pull rod, the ash removal plate slides along the heat exchange discharge pipe, and the heat exchange discharge pipe can be placed on the The soot is scraped off; the appearance of the shell water jacket can be rectangular or cylindrical.

The utility model has the advantages of not only improving the thermal efficiency of the heating furnace, saving fuel consumption, but also reducing the discharge of harmful substances, improving the living environment of people, and being convenient for people to use hot water.

There are two ways to use it:

1. Connect the utility model to the smoke outlet of the civil heating furnace through the smoke inlet and outlet, and then connect the cold water inlet and the hot water outlet with the cold and hot water pipes in the heating system of the heating furnace, so that Improve thermal efficiency within the system and reduce costs.

2. Connect the utility model to the smoke outlet of the civil heating furnace through the smoke inlet and outlet, and then connect the cold water inlet and the hot water outlet with the cold and hot water pipes respectively, and use it as a hot water system alone (can Provide 60-80 ℃ hot water), can provide domestic water in winter without interruption, can be used for bathing, washing clothes, washing vegetables, etc., which is convenient for people's life.
