[0003] The existing multi-circuit heat exchange boiler device only installs multiple loop pipes on the outer wall of the boiler. However, since the length of these loop pipes is relatively fixed, the temperature of the water flowing through the loop pipes cannot be effectively adjusted. Secondly, the high-temperature flue gas generated by the combustion inside the boiler is directly discharged without being effectively utilized, resulting in a significant reduction in heat utilization efficiency and the inability to perform effective conversion.

[0004] Therefore, we provide a boiler device with multi-circuit heat exchange. Utility Model Content

[0005] The purpose of the utility model is to provide a boiler device with multi-circuit heat exchange to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a boiler device with multi-circuit heat exchange, comprising a boiler, a circuit component 1 and a smoke exhaust component, wherein a furnace door is installed on the front side of the boiler, a base is installed on the lower end of the boiler, a circuit component 1 is installed on the outer side of the boiler, a circuit component 2 is sleeved on the outer side of the circuit component 1, a heating chamber is installed on the outer side of the circuit component 2, the heating chamber is connected and sealed with the boiler, and the heating chamber is filled with heat transfer oil, a smoke exhaust component is installed on the outer side of the heating chamber, and an outer furnace wall is welded to the outer side of the smoke exhaust component;

[0007] The circuit component 1 includes an inlet pipe, a straight pipe, an elbow pipe 1 and an outlet pipe. The lower end of the heating chamber is penetrated by an inlet pipe, the upper end of the inlet pipe is connected to a straight pipe, the other side of the inlet pipe is connected to an elbow pipe 1, and the top end of the straight pipe is connected to the outlet pipe.

[0008] Preferably, valve one is fixedly installed at both ends of the straight-through pipe, and valve two is fixedly installed at both ends of the curved-through pipe one.

[0009] Preferably, a four-way pipe is fixedly mounted on the upper end of the straight pipe, and one side of the four-way pipe is connected to the end of the first curved pipe.

[0010] Preferably, a second elbow pipe is fixedly installed on the other side of the four-way pipe, and valves three are fixedly installed on both ends of the second elbow pipe.

[0011] Preferably, the smoke exhaust assembly is composed of an annular smoke exhaust plate 1 and an annular smoke exhaust plate 2, and the annular smoke exhaust plate 1 and the annular smoke exhaust plate 2 are staggered with each other and welded to the outer wall of the heating chamber.

[0012] Preferably, a filter is connected to the lower end of one side of the boiler through a pipeline, and the other end of the filter is connected to the interior of the annular smoke exhaust plate at the bottom through a connecting pipe.

[0013] Preferably, a smoke outlet 1 is provided on one side of the upper surface of the annular smoke exhaust plate 1, a smoke outlet 2 is provided on one side of the upper surface of the annular smoke exhaust plate 2, and the smoke outlet 1 and the smoke outlet 2 are centrally symmetrically distributed, and the upper end of the uppermost annular smoke exhaust plate 2 is connected to a smoke exhaust pipe.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The boiler device with multi-circuit heat exchange can adjust the heating temperature of water according to actual use through the setting of the circuit component one. When a lower temperature is required, the valve two at both ends of the first and last ends of the elbow pipe and the valve three at both ends of the second elbow pipe can be closed, and the valves one of all the straight pipes can be opened. At this time, the water will pass through the water inlet pipe and the straight pipe and directly flow out from the water outlet pipe. When an extremely high temperature is required, the transmission length of the water in the circuit component one can be extended, the valves one at both ends of the straight pipe can be closed, and the valves two at both ends of the first and last ends of the elbow pipe and the valves three at both ends of the second elbow pipe can be opened. At this time, the water will flow along the circuit formed by the elbow pipe one and the elbow pipe two, so as to reach a higher temperature. When other temperatures are required, the straight pipe, the elbow pipe one and the elbow pipe two can be selected to be used in combination with each other, and the heating temperature of the water can be adjusted by changing the length of the water flowing in the heating chamber.

[0016] 2. Through the setting of the smoke exhaust component, the high-temperature smoke flows in the enclosed space formed by the annular smoke exhaust plate 1 and the annular smoke exhaust plate 2, and then is discharged from the smoke outlet 1 and the smoke outlet 2, and finally is discharged from the smoke exhaust pipe. While the high-temperature smoke flows in the smoke exhaust component, it will provide heat on the outside of the heating chamber, so that the heat transfer oil inside the heating chamber will heat up at a faster rate, which can effectively make full and effective use of the high-temperature smoke generated by combustion, greatly increasing the heat utilization efficiency.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The circuit component 4 includes an inlet pipe 41, a straight pipe 42, a bent pipe 43 and an outlet pipe 46. The lower end of the heating chamber 6 is penetrated by the inlet pipe 41, the upper end of the inlet pipe 41 is connected to the straight pipe 42, the other side of the inlet pipe 41 is connected to the bent pipe 43, and the top end of the straight pipe 42 is connected to the outlet pipe 46.

[0026] Furthermore, valve 1 421 is fixedly installed at both ends of the straight pipe 42, and valve 1 421 is used to control the connectivity of the straight pipe 42. Valve 2 431 is fixedly installed at both ends of the curved pipe 43, and valve 2 431 is used to control the connectivity of the curved pipe 43.

[0027] Furthermore, a cross-tube 44 is fixedly installed on the upper end of the straight tube 42 , one side of the cross-tube 44 is connected to the end of the elbow tube 1 43 , and the cross-tube 44 is used to connect the straight tube 42 , the elbow tube 1 43 and the elbow tube 2 45 .

[0028] Furthermore, a second elbow pipe 45 is fixedly installed on the other side of the four-way pipe 44 , and a third valve 451 is fixedly installed at both ends of the second elbow pipe 45 . The third valve 451 is used to control the connection of the second elbow pipe 45 .

[0029] Furthermore, the smoke exhaust assembly 7 is composed of an annular smoke exhaust plate 1 71 and an annular smoke exhaust plate 2 72, and the annular smoke exhaust plate 1 71 and the annular smoke exhaust plate 2 72 are staggered with each other and welded to the outer wall of the heating chamber 6. The annular smoke exhaust plate 1 71 and the annular smoke exhaust plate 2 72 form an enclosed space to provide a flow path for the flow of high-temperature smoke.

[0030] Furthermore, a filter 11 is connected to the lower end of one side of the boiler 1 through a pipe, and the other end of the filter 11 is connected to the interior of the annular smoke exhaust plate 71 at the bottom through a connecting pipe 12. Before the high-temperature flue gas enters the smoke exhaust assembly 7, it will pass through the filter 11 for dust filtering to prevent dust in the high-temperature flue gas from entering the enclosed space formed by the annular smoke exhaust plate 1 71 and the annular smoke exhaust plate 2 72.

[0031] Furthermore, a smoke outlet 1 711 is provided on one side of the upper surface of the annular smoke exhaust plate 1 71, and a smoke outlet 2 721 is provided on one side of the upper surface of the annular smoke exhaust plate 2 72, and the smoke outlet 1 711 and the smoke outlet 2 721 are centrally symmetrically distributed, and the positions of the smoke outlet 1 711 and the smoke outlet 2 721 are relative, so that the high-temperature flue gas can flow fully in the enclosed space, making the heat exchange efficiency higher, and the upper end of the uppermost annular smoke exhaust plate 2 72 is connected to the smoke exhaust pipe 722.

[0032] Working principle: First, a multi-circuit heat exchange boiler device is moved to the working position. In the first step, when the boiler 1 is in the working state, the internal combustion of the boiler 1 continues to transfer the heat to the outer wall of the boiler 1. In the second step, the heat generated by the outer wall of the boiler 1 will be transferred to the heat transfer oil in the heating chamber 6, so that the heat transfer oil is in a high temperature state. In the third step, the water to be heated is injected from the water inlet pipe 41 at this time, and the heating temperature of the water can be adjusted according to the actual use. When a lower temperature is required, the valve 2 431 at both ends of the bend pipe 1 43 and the valve 3 451 at both ends of the bend pipe 2 45 can be closed, and the valve 1 421 of all the straight pipes 42 can be opened. At this time, the water will pass through the water inlet pipe 41 and the straight pipe 42 and flow directly out of the water outlet pipe 46. In the fourth step, when an extremely high temperature is required, the transmission length of the water in the loop component 1 4 can be extended, and the straight pipe 4 2, the valves 421 at both ends are all closed, and the valves 431 at both ends of the elbow pipe 43 and the valves 451 at both ends of the elbow pipe 45 are opened. At this time, water will flow along the loop formed by the elbow pipe 43 and the elbow pipe 45, thereby reaching a higher temperature. In the fifth step, the high-temperature flue gas generated by the combustion inside the boiler 1 will pass through the filter 11 to filter the waste dust, enter the exhaust assembly 7 through the connecting pipe 12, flow in the closed space formed by the annular exhaust plate 1 71 and the annular exhaust plate 2 72, and then be discharged from the smoke outlet 1 711 and the smoke outlet 2 721, and finally be discharged from the exhaust pipe 722. While the high-temperature flue gas flows in the exhaust assembly 7, it will provide heat on the outside of the heating chamber 6, so that the heat transfer oil inside the heating chamber 6 will heat up at a faster rate, thus completing the use process of a boiler device with multi-loop heat exchange.

All the electrical components mentioned above are made of high temperature resistant materials.
