RIO system is mainly composed of combustion chamber, heat exchanger and waste gas pipeline, and its treatment principle mainly includes three processes: waste gas preheating, combustion oxidation and heat energy recovery.

[0003] like Figure 3 As shown, this is the furnace chamber structure of the previous generation of RTO thermal storage combustion furnace. The burner is installed at the rear end of the furnace chamber, and the flame generated by the burner is horizontally distributed between the first thermal storage chamber and the second thermal storage chamber. Although the heat exchanger can recycle most of the heat generated by the burner when it is working, there is still a small part of the waste heat that is not fully utilized and is discharged, resulting in heat loss problems when the RTO thermal storage combustion furnace is working, reducing the thermal efficiency of the RTO thermal storage combustion furnace when it is working.

[0004] In view of this, it is particularly important to design and manufacture a furnace chamber structure that can further recover and reuse waste heat and reduce heat loss during the operation of the RTO thermal storage combustion furnace, and to apply it in the RTO thermal storage combustion furnace.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] As a further description of the above technical solution:

[0011] A circulating oil pump connected with a metal oil pipe liquid path is installed on the inner side of the furnace cavity below the heat absorbing plate.

[0012] As a further description of the above technical solution:

[0013] The heat absorbing ring, the first heat conducting sleeve, the heat absorbing plate and the second heat conducting sleeve are all hollow structures, and the inner cavities of the heat absorbing ring, the first heat conducting sleeve, the heat absorbing plate and the second heat conducting sleeve are filled with heat conducting oil.

The heat absorbing ring and the heat absorbing plate can absorb the heat of the inner flame and the outer flame of the flame respectively. When the circulating oil pump is working, the heat conducting oil inside the heat absorbing ring, the first heat conducting sleeve, the heat absorbing plate and the second heat conducting sleeve can circulate, and the heat absorbed by the heat absorbing ring will be conducted to the first heat conducting sleeve through the heat conducting oil in advance. The first heat-conducting sleeve will conduct the heat inward to the first heat storage chamber, and the heat absorbed by the heat-absorbing plate will be conducted to the second heat-conducting sleeve through the heat-conducting oil in advance, and the second heat-conducting sleeve will conduct the heat inward to the second heat storage chamber, accelerating the temperature rise of the first heat storage chamber and the second heat storage chamber and improving the subsequent thermal insulation effect of the heat storage chamber.

Based on the embodiments of 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.

[0026] See also Figure 1-3 The utility model provides a technical solution: a furnace chamber structure for an energy-saving RTO heat storage combustion furnace, comprising a furnace chamber 1, a first heat storage chamber 2 arranged on the left side of the lower end of the furnace chamber 1, a second heat storage chamber 3 arranged on the right side of the lower end of the furnace chamber 1, a heat preservation layer 4 filled between the furnace chamber 1, the first heat storage chamber 2 and the second heat storage chamber 3, and a burner 5 arranged outside the furnace chamber 1, the burner 5 is installed in the middle of the upper end of the furnace chamber 1, the nozzle of the burner 5 vertically penetrates the furnace chamber 1 and extends to the inside of the furnace chamber 1, and a heat recovery mechanism for recovering waste heat to reduce heat loss of the furnace body is arranged between the furnace chamber 1, the first heat storage chamber 2, the second heat storage chamber 3 and the burner 5.

[0027] Specifically, Figure 1 and Figure 2As shown, the heat recovery mechanism includes a heat absorbing ring 6 installed on the top of the inner side of the furnace cavity 1 and located outside the nozzle of the burner 5, a first heat conductive sleeve 7 sleeved on the outside of the first heat storage chamber 2, a heat absorbing plate 8 installed in the middle of the inner side of the furnace cavity 1 and located directly below the nozzle of the burner 5, a second heat conductive sleeve 9 sleeved on the outside of the second heat storage chamber 3, and a metal oil pipe 10 connected between the heat absorbing ring 6, the first heat conductive sleeve 7, the heat absorbing plate 8 and the second heat conductive sleeve 9. A circulating oil pump 11 connected with the metal oil pipe 10 is installed on the inner side of the furnace cavity 1 below the heat absorbing plate 8. When the circulating oil pump 11 is working, the heat-conducting oil can generate a counterclockwise circulation flow between the heat absorbing ring 6, the first heat conductive sleeve 7, the heat absorbing plate 8 and the second heat conductive sleeve 9, and the residual heat can be absorbed and conducted to the first heat conductive sleeve 7 and the second heat conductive sleeve 9, so as to realize auxiliary heating and heat locking and heat preservation treatment of the first heat storage chamber 2 and the second heat storage chamber 3.

[0028] Specifically, Figure 1 and Figure 2 As shown, the heat absorption ring 6, the first heat conductive sleeve 7, the heat absorption plate 8 and the second heat conductive sleeve 9 are all hollow structures, and the inner cavities of the heat absorption ring 6, the first heat conductive sleeve 7, the heat absorption plate 8 and the second heat conductive sleeve 9 are filled with heat-conducting oil. At the same time, the heat absorption ring 6, the first heat conductive sleeve 7, the heat absorption plate 8, the second heat conductive sleeve 9 and the metal oil pipe 10 are all made of copper material. The selection of this material improves the thermal conductivity of the heat absorption ring 6, the first heat conductive sleeve 7, the heat absorption plate 8, the second heat conductive sleeve 9 and the metal oil pipe 10, accelerates the absorption and conduction rate of heat by the heat absorption ring 6, the first heat conductive sleeve 7, the heat absorption plate 8, the second heat conductive sleeve 9 and the metal oil pipe 10, thereby reducing the heat loss during the heat conduction process.

[0029] Specifically, Figure 1 and Figure 2 As shown, an oil tank 12 is installed on the left side of the upper end of the furnace chamber 1, and a liquid circuit is established between the oil tank 12 and the metal oil pipe 10 through an electromagnetic control valve 13.

The heat-absorbing ring 6 can absorb the heat of the inner flame of the flame generated by the burner 5 and conduct it inward to the heat-conducting oil. The heat-conducting oil can The absorbed heat is circulated and transported to the first heat-conducting sleeve 7, and the first heat-conducting sleeve 7 will conduct the heat outward to the first heat storage chamber 2, thereby accelerating the heating operation of the first heat storage chamber 2. The heat-conducting oil after preliminary heating will enter the heat-absorbing plate 8 through the metal oil pipe 10, and the heat-absorbing plate 8 can absorb the heat of the outer flame of the flame and conduct it inward to the heat-conducting oil, thereby performing a secondary heating treatment on the heat-conducting oil. The heated heat-conducting oil will be transported to the second heat-conducting sleeve 9 through the metal oil pipe 10, and the second heat-conducting sleeve 9 will conduct the heat outward to the second heat storage chamber 3, thereby accelerating the heating operation of the second heat storage chamber 3, thereby performing multiple absorption of the waste heat generated during the operation of the burner 5, and accelerating the heating and heating and heat preservation treatment of the first heat storage chamber 2 and the second heat storage chamber 3.
