As shown in fig. 1-7, a tail gas combustion device for harmless treatment of waste electrolyte structurally comprises a carbonization furnace connecting pipe 11, a combustor 12, an induced draft fan 13, a smoke detector 14, a ventilation pipe 15, a fire-resistant combustion box unit 1 for installing the carbonization furnace connecting pipe 11 and the combustor 12, a bending connecting pipe 2 arranged on the fire-resistant combustion box unit 1 and provided with the induced draft fan 13, a smoke water-cooling box unit 3 arranged on the bending connecting pipe 2, an outer water-cooling cover unit 4 arranged on the smoke water-cooling box unit 3 and used for falling water on the upper surface of the smoke water-cooling box unit 3 and used for cooling the combustor 12, and a bending air outlet pipe 5 arranged on the smoke water-cooling box unit 3 and provided with the induced draft fan 13 and the smoke detector 14.
In this embodiment, the upstream of the connecting pipe 11 of the carbonization furnace is a carbonization furnace for innocent treatment of waste lithium batteries, and the waste electrolyte can be subjected to innocent treatment in the carbonization furnace, so as to generate flue gas which needs to be subjected to treatments such as burning, dust removal, alkali liquor absorption and the like in sequence.
The combustor 12, the induced draft fan 13 and the smoke detector 14 are all existing commercial devices, and the connecting pipe 11, the ventilation pipe 15, the bending connecting pipe 2 and the bending air outlet pipe 5 are all made of refractory materials.
In addition, the upper and lower both sides of flue gas water-cooling case unit 3 all are equipped with water-cooling facility, upwards spray water a promptly and be used for cooling the flue gas, and downward spray water b is used for flue gas cooling earlier, and then is used for combustor 12 cooling, and consequently downward spray water b's water yield is greater than upward spray water a, guarantees finally: 1. when the flue gas enters a dust removing cloth bag, an alkali liquor absorption tower and other post-treatment equipment, the temperature of the flue gas is proper; 2. the operating environment temperature of the combustor 12 does not exceed 70 ℃.
And the height of the upper surface of the outer water-cooling cover unit 4 is lower than that of the upper surface of the flue gas water-cooling box unit 3, so that the downward spraying water body b can be used for water-cooling the outer water-cooling cover unit 4 again. In addition, the outside water-cooling cover unit 4 also needs to isolate the water body from the burner 12 and isolate the water body from the fire-resistant combustion box unit 1, so that the short circuit burning of the burner 12 and the quenching cracking of the fire-resistant combustion box unit 1 are avoided.
Finally, the temperature of the environment where the smoke detector 14 is used, that is, the smoke temperature is obtained by directly and greatly cooling the smoke water-cooling box unit 3, and a special water-cooling structure is not required to be provided for the smoke detector 14, so that the smoke detector is very ingenious.
The fire-resistant combustion case unit 1 includes a rectangular box 101 provided with the carbonization furnace connection pipe 11 and the burner 12 and the ventilation pipe 15, a partition plate 102 provided in the rectangular box 101 and used for partitioning to form a transverse reciprocating passage, and an air outlet 103 provided on the rectangular box 101 and used for installing the bent connection pipe 2.

In this embodiment, the smoke water cooling tank unit 3 is only provided with openings at the positions of the bending connecting pipe 2 and the bending air outlet pipe 5, and the rest positions are closed so as to avoid the water body for cooling from entering the smoke and the smoke from leaking.
The smoke water cooling box unit 3 is made of stainless steel sheets, so that sufficient heat conduction efficiency and corrosion resistance effect are guaranteed, and the front end plate 301 and the rear end plate 302 are in front contact and rear contact effects in the smoke advancing direction in the front-rear sequence, and are rectangular in shape.
In addition, a plurality of the lower open boxes 304 are used for plugging all the openings on the opening bottom plate 303, so as to ensure that the flue gas water cooling box unit 3 is sealed sufficiently. The single lower open box 304 comprises a total of 5 plates at the top, back, forth, left and right, the roles of which are mainly 2:
firstly, the effective contact area of the flue gas and the upward spraying water body a is enlarged, and the water cooling speed and degree of the flue gas are improved;
and secondly, blocking the smoke in the advancing process, prolonging the passing time of the smoke in the smoke water cooling box unit 3, and further indirectly improving the water cooling effect.
The flue gas water cooling tank unit 3 further comprises a high-level plate 305 and a low-level plate 306 which are arranged on the front end plate 301 and the rear end plate 302 and are respectively positioned at two sides, and an inclined plate 307 which is arranged on the high-level plate 305 and the low-level plate 306 and is used for guiding the cooling water body to the outer water cooling cover unit 4.
In this embodiment, the bottom edges of the front end plate 301, the rear end plate 302, the upper plate 305 and the lower plate 306 are flush, and the inclined plate 307 ensures that the downward spraying water body b can be cooled and utilized for the second time on the outer water cooling cover unit 4.
Of course, the 4 sides of the rectangular inclined plate 307 are also in sealing connection, so that the downward spraying water body b is prevented from entering the flue gas water cooling box unit 3, and the flue gas is prevented from leaking at the flue gas water cooling box unit 3.
The flue gas water cooling tank unit 3 further comprises a groove 308 which is arranged on the inclined plate 307 and is used for intercepting the cooling water body.
In this embodiment, the groove 308 has the function of prolonging the contact time between the downward spraying water body b and the flue gas, and further improving the water cooling strength.
