[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0021] The utility model provides a sanding powder burning organic heat carrier furnace, such as Figure 1-Figure 3 As shown, it includes an upper furnace body 1 and a lower furnace body 2. A plurality of heat exchange tubes 12 are arranged inside the upper furnace body 1 for heat exchange. A combustion chamber is arranged inside the lower furnace body 2 for burning fuel. A grate 23 is installed in the combustion chamber. A plurality of smoke folding walls 13 are installed at one end of the upper furnace body 1. The smoke folding walls 13 are arranged vertically to form a serpentine smoke passage inside the upper furnace body 1. A foundation 3 is installed at the bottom of the lower furnace body 2. A flue 4 is connected to one end of the upper furnace body 1. The bottom of the upper furnace body 1 is communicated with the top of the lower furnace body 2.
[0022] In this embodiment, the heat exchange tubes 12 are distributed in a serpentine shape inside the upper furnace body 1 .
[0023] Specifically, both ends of the heat exchange tube 12 are respectively connected to the medium inlet and outlet of the external heat-using equipment.
[0024] Furthermore, a feed port 22 is provided on the outer wall of one side of the lower furnace body 2. The raw material is sanding powder, which is a fine granular powder. The main components are substances such as aluminum oxide or silicate. The sanding powder enters the combustion chamber from the feed port 22 for combustion. A furnace door 21 is installed on the outer wall of the lower furnace body 2 near the grate 23 to facilitate opening for operation of the grate 23.
[0025] Furthermore, a soot blowing port 11 is provided at the top of the upper furnace body 1 near the serpentine flue gas passage, for blowing the dust inside the upper furnace body 1 downward.
[0026] Furthermore, an ash collecting bin 6 is installed at the bottom of the upper furnace body 1 near the smoke folding wall 13, and an ash cleaning port 61 is provided at the bottom of the ash collecting bin 6 for blowing out ash downwards.
[0027] Furthermore, a ladder 7 is installed on one side outer wall of the upper furnace body 1 for maintenance personnel to climb to the top to perform maintenance operations.
[0028] Furthermore, a foundation pit is provided at the bottom of the grate 23 of the foundation 3 near the lower furnace body 2 for dust to accumulate inside the foundation pit.
[0029] When the sanding powder organic heat carrier furnace of the utility model is in use, the sanding powder is first fed into the combustion chamber inside the lower furnace body 2 from the feed port 22, and burned through the grate 23. The smoke generated by the combustion enters the upper furnace body 1 upward, and exchanges heat with the serpentine heat exchange tube 12. Heat transfer oil is fed into one end of the heat exchange tube 12, and is discharged from the other end after being inhaled, and is used for heat-using equipment. The smoke is guided by the smoke folding wall 13 to increase the smoke stroke and block the dust in the smoke. The dust enters the ash collecting bin 6 downward and is discharged through the ash cleaning port 61. After long-term use, air is blown downward through the ash blowing port 11 to blow the dust attached to the smoke folding wall 13 downward, and the dust enters the ash collecting bin 6. After the dust in the ash collecting bin 6 is full, it is blown downward through the ash cleaning port 61.
[0030] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
