Embodiment 1

[0026] Such as figure 1 As shown, a water heating system includes a hot water tank 1, a combustion stove 6, and a flue gas pipe 5 for exhausting smoke from the combustion stove, and also includes a heat-conducting oil pipe 2 for containing heat-conducting oil, and the heat-conducting oil pipe 2 is annular Pipeline, the heat conduction oil pipe 2 passes through the hot water tank 1 and the flue gas pipe 5;

[0027] It also includes at least two expansion joints 3, the expansion joints 3 are connected in series on the heat transfer oil pipe 2, and at least one expansion joint 3 is provided on the heat transfer oil pipe 2 inside the hot water tank 1 and the heat transfer oil pipe 2 outside the hot water tank 1 ;

[0028] It also includes a circulation pump 4 for driving the heat transfer oil in the heat transfer oil pipe 2 to circulate.

[0029] Specifically, the above-mentioned combustion stove 6 is used for burning straw fuel, and the high-temperature flue gas produced is dis...

Embodiment 2

[0032] Such as figure 1 As shown, this embodiment is further limited on the basis of Embodiment 1: since the hot water tank 1 is connected to the water pipe network, it is equivalent to an internal pressure container, in order to make the hot water tank 1 have better pressure resistance , the hot water tank 1 includes a cylindrical body and heads respectively fixed to different ends of the body, and the heads are hemispherical or elliptical.

[0033] In order to facilitate the installation and maintenance of the heat transfer oil pipe 2 in the hot water tank 1, one of the sealing heads is connected to the flange of the barrel body, and the other sealing head is connected to the barrel body by welding.

[0034] Since the density of water with a higher temperature is smaller than that of water with a lower temperature, in order to ensure that the water discharged from the hot water tank 1 is hot water as much as possible, the hot water tank 1 is also connected with an inlet pipe...

Abstract

The invention discloses a water heating system. The water heating system comprises a hot water tank, a combustion stove and a flue gas pipe for flue gas exhaust of the combustion stove. The water heating system further comprises a heat conducting oil pipe for containing heat conducting oil. The heat conducting oil pipe is an annular pipe, and the heat conducting oil pipe passes through the hot water tank and the flue gas pipe. The water heating system further comprises at least two expansion joints, the expansion joints are connected to the heat conducting oil pipe in series, and the portions, inside and outside the hot water tank, of the heat conducting oil pipe are both provided with at least one expansion joint. The water heating system further comprises a circulating pump for driving the heat conducting oil in the heat conducting oil pipe to cyclically flow. By means of the system, the problem that when straw serves as a heat source to heat water, the heated face of the water easily scales can be solved.

Description

technical field [0001] The invention relates to the technical field of fluid heating equipment, in particular to a water heating system. Background technique [0002] Hot water is an indispensable domestic water in people's daily life. In the prior art, gas-fired water heaters, electric water heaters, and solar water heaters all provide quick ways to obtain hot water. [0003] Nowadays, the combustion technology of crop stalks and tree branches has been developed, and the following combustion technology has appeared in the existing technology: put the straw and branches into the primary fuel chamber for combustion, and control the air intake volume of the primary fuel chamber , so that the flue gas exhausted from the primary fuel chamber contains a large amount of combustible gas, and the above combustible gas is used for the next combustion. In this way, less harmful substances are produced due to the combustion of combustible gas, which makes this combustion technology com...
