[0022] 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.

[0023] Embodiment 1

[0024] See also Figures 1 to 5 The utility model provides an embodiment: a waste heat recovery device for palm oil gelatinization equipment, comprising:

[0025] A waste heat recovery box 101, a filter box 201 and a negative pressure box 301, wherein the upper end surface of the waste heat recovery box 101 is provided with a steam exhaust pipe 103, and a water inlet pipe 102 is installed at the upper end of the waste heat recovery box 101 at a symmetrical position of the steam exhaust pipe 103, and a heat exchange coil 105 is arranged in the waste heat recovery box 101, and the beginning and the end of the heat exchange coil 105 are extended out of the waste heat recovery box 101 and a trumpet pipe 106 is installed;

[0026] The filter box 201 is installed at the front end of the waste heat recovery box 101, and the trumpet tube 106 at the starting end of the heat exchange coil 105 is located in the filter box 201. The upper end of the filter box 201 is provided with symmetrically distributed installation openings 204, and an activated carbon filter layer 205 is arranged from the installation openings 204 to the filter box 201. The lower end of the filter box 201 is installed with an oil collection box 203, and the inner wall of the bottom end of the filter box 201 is provided with an oil leakage hole, which is connected to the oil collection box 203.

[0027] In this embodiment, the chimney of the palm oil gelatinization equipment is connected to the oil fume inlet pipe 202 through a pipeline, and water is added to the waste heat recovery box 101 through the water inlet pipe 102. During operation, the oil fume enters the filter box 201 from the oil fume inlet pipe 202, and the oil fume can be filtered through the activated carbon filter layer 205 to filter the oil stains in the oil fume. The filtered oil stains naturally flow down through the oil leakage hole into the oil collection box 203 for collection, and the filtered oil fume can enter the heat exchange coil 105. The waste heat in the oil fume in the heat exchange coil 105 can heat the water in the waste heat recovery box 101. The heated water and the steam generated by the heated water can be utilized, and the waste heat in the oil fume can be recycled.

[0028] Furthermore,

[0029] A drain pipe 104 is disposed at the lower end of the waste heat recovery box 101 , and valves are disposed on the water inlet pipe 102 , the steam exhaust pipe 103 and the drain pipe 104 .

[0030] When the water heated in the waste heat recovery box 101 needs to be used, it can be discharged through the drain pipe 104. When the water is heated to generate steam, the steam can be discharged through the steam discharge pipe 103 for use.

[0031] Furthermore,

[0032] A fume inlet pipe 202 is installed at the front end of the filter box 201 , and the fume inlet pipe 202 is connected to the filter box 201 .

[0033] The oil smoke can enter the filter box 201 through the oil smoke inlet pipe 202 .

[0034] Furthermore,

[0035] An oil drain pipe is installed at the lower end of the oil collecting box 203, and a valve is arranged on the oil drain pipe.

[0036] When a lot of oil is collected in the oil collecting box 203, the valve on the oil drain pipe is opened, and the oil in the oil collecting box 203 can be discharged through the oil drain pipe.

[0037] Furthermore,

[0038] The upper end of the filter box 201 is covered at the mounting opening 204 with a limiting cover plate 206, and mounting holes distributed in an array are opened on the limiting cover plate 206. The filter box 201 is opened with threaded holes corresponding to the mounting holes, and bolts are installed in the mounting holes and the threads in the threaded holes.

[0039] The setting of the limiting cover plate 206 is used to limit the activated carbon filter layer 205. When the activated carbon filter layer 205 needs to be cleaned or replaced, the limiting cover plate 206 can be removed by removing the bolts on the limiting cover plate 206, so that the activated carbon filter layer 205 can be easily removed from the installation port 204.

[0040] Embodiment 2

[0041] See also Figures 1 to 5 The utility model provides an embodiment: a waste heat recovery device for palm oil gelatinization equipment. Compared with the first embodiment, the present embodiment further includes:

[0042] The negative pressure box 301 is installed at the rear end of the waste heat recovery box 101, and the trumpet tube 106 at the end of the heat exchange coil 105 is located in the negative pressure box 301. The negative pressure box 301 is installed with symmetrically distributed fixing rods 302, and a driving device 303 is installed between the fixing rods 302. The fan blades 304 are installed at the end of the main shaft of the driving device 303, and an exhaust port 305 is opened at the side end of the negative pressure box 301.

[0043] In this embodiment, when the waste heat of the oil fume is recovered, the fan blades 304 can be made to rotate at a high speed by driving the device 303. The high-speed rotation of the fan blades 304 can generate a negative pressure in the negative pressure box 301, thereby generating a negative pressure in the heat exchange coil 105 and the filter box 201, which can effectively increase the speed of oil fume filtration and cooperate with the oil fume filtration work. The oil fume after heat exchange can be discharged from the exhaust port 305.
