Description

Technical Field

[0001] The utility model belongs to the technical field of waste heat recovery devices, and in particular relates to a waste heat recovery device for a civilian stove using a new energy fuel. Background Art

[0002] New energy fuel is generally natural gas, which is increasingly popular due to its large air intake, fast combustion speed and high temperature during use. However, in the prior art, when stoves use new energy fuels to cook or boil water, a considerable amount of heat is lost in the air and cannot be used efficiently, which causes waste to a certain extent.

[0003] After searching, a stove waste heat recovery device disclosed in the application number "CN201721749837.1" is also an increasingly mature technology, including a shell, a heat conductor and a heating element. Heat conductors are plugged into the four corners of the top of the shell, the bottom of the heat conductor passes through the top of the shell and extends to the inner cavity of the shell and is connected to the heating element. A temperature sensor is installed at the bottom of the inner cavity of the shell, a pressure sensor is installed on the left side of the temperature sensor, the right end of the shell is connected to a water inlet pipe, and a first solenoid valve is plugged into the outside of the water inlet pipe. The utility model absorbs heat through the heat conducting element and then transfers it to the heating element, heats the water in the shell, and recycles the waste heat, thus avoiding waste caused by heat loss. It is intelligently controlled by the smart box, and the operation is quick and convenient. The temperature sensor feeds back data. When it is greater than the preset value, the water in the shell is recycled and refilled with water for heating, so as to maximize the utilization of heat and avoid waste. It is relatively practical and suitable for wide promotion and use. However, the above-mentioned waste heat recovery device still has certain shortcomings in use. For example, during the water heating process, the water is in the shell, so the heat will be absorbed by the shell because of the water being in the shell, and then more heat energy will need to be recovered to maintain the temperature of the water. At the same time, the loss of heat energy can also be greatly increased, thereby reducing the practicality of the waste heat recovery device. Utility Model Content
