Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1, a novel gas waste heat recycling device comprises a heat collecting cover 11, a water storage tank 4, a circulating water inlet pipe 1 and a circulating water outlet pipe 15.
The heat collecting cover 11 is a spiral copper pipe, the whole body is in a cone shape, the upper part is large, the lower part is small, the heat collecting cover 11 is arranged around a fire outlet of the gas stove 14, and a ventilation gap 12 of the heat collecting cover 11 is convenient for air to be in full contact with gas for combustion.
The water storage tank 4 is positioned above the gas stove 14, is rectangular in shape and is provided with an insulating layer on the outer side. The heat collecting cover 11 and the water storage tank 4 are connected by the circulating water inlet pipe 1 and the circulating water outlet pipe 15 to form a closed water circulating system.
The circulating water inlet pipe 1 is connected to the lower end of the heat collecting cover 11 from one side of the bottom of the water storage tank 4, and the connection point of the pipeline and the heat collecting cover 11 is required to be positioned below the heat collecting cover 11 and has a certain height difference; one end of a circulating water outlet pipe 15 is connected with the upper end of the heat collecting cover 11, and the other end is connected with the other side of the bottom of the water storage tank 4.
Before the novel gas waste heat recycling device works, the closed water circulation system is filled with cold water, when the gas stove 14 works, the temperature of the cold water in the heat collection cover 11 rises after absorbing heat around the fire hole, the density of the cold water is reduced, and the cold water is driven by the cold water with larger density flowing out of the water storage tank 4, so that the hot water gradually rises spirally in the heat collection cover 11 to enter the circulating water outlet pipe 15 and continuously rises to enter the water storage tank 4, and thus, the circulating flow in the direction shown by an arrow in figure 1 is formed. It can be seen that the water circulation acting pressure between the heat collecting cover 11 and the water storage tank 4 depends on the density change of water in the closed water circulation system.
When a user needs hot water, the water outlet valve 9 on the hot water outlet pipe 10 of the water storage tank 4 is opened. The water level of the water storage tank 4 descends, the ball float valve 8 descends along with the liquid level, when the water level reaches the lower limit, the water supplementing valve 6 is driven to be opened through the connecting rod, and cold water flows into the water storage tank 4 through the water supplementing pipe 7; the water level of the water storage tank 4 rises gradually, the ball float valve 8 rises along with the liquid level, and when the water level reaches the upper limit, the water replenishing valve 6 is driven to close through the connecting rod, and the water replenishing is stopped. In addition, the water storage tank 4 is provided with a temperature display 5 for displaying the internal water temperature in real time.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the contents that do not depart from the technical solution of the present invention belong to the technical solution of the present invention.
