[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1 The circuit board processing device of the first embodiment of the utility model includes: a discharge box 100, an exhaust port is arranged at the upper part of the discharge box 100, and a waste outlet 101 is arranged at the lower part of the discharge box 100; a spray mechanism, one end of the spray mechanism is connected to the exhaust port; a separation mechanism, one end of the separation mechanism is connected to the other end of the spray mechanism; an adsorption mechanism, including at least two adsorption tanks 400, adsorption resin is arranged in the adsorption tank 400, the feed end of the adsorption tank 400 is connected to the discharge end of the separation mechanism, and the discharge end of the adsorption tank 400 is connected to the water inlet end of the spray mechanism.

[0027] After the circuit board is pyrolyzed, the pyrolysis gas and the pyrolysis slag are separated through the discharge box 100. The pyrolysis gas passes through the spraying mechanism to generate pyrolysis oil and non-condensable gas. The pyrolysis oil continues to be introduced into the separation mechanism to separate the bromine-containing wastewater. The bromide ions in the wastewater are then replaced through the adsorption tank 400 to achieve bromine recovery and improve resource utilization.

[0028] The adsorption tank 400 is filled with a bromine removal resin. The bromide ions in the bromine-containing wastewater are exchanged with the bromine removal resin to solidify the bromine on the resin. When one adsorption tank 400 is saturated, it can be switched to another adsorption tank 400 for continued adsorption. The bromine-enriched solution can be obtained by passing the analytical solution into the adsorption tank 400 with saturated adsorption, and the bromine recovery is completed. In addition, after the bromine-containing wastewater is passed into the adsorption tank 400, the bromide ions are adsorbed, the wastewater is purified, and then the wastewater is transported to the spray mechanism for recycling.

[0029] It is understandable that, referring to Figure 1 and Figure 2 The discharge box 100 is provided with a first baffle 110 and a second baffle, the first baffle 110 is provided below the second baffle, a gap is formed between the second baffle and the side wall of the discharge box 100, and the feed port of the discharge box 100 is provided between the first baffle 110 and the waste outlet 101. By providing the first baffle 110 and the second baffle, the flow rate of the pyrolysis gas entering the spray mechanism is controlled to avoid the pyrolysis gas failing to be completely condensed in the spray mechanism, resulting in insufficient bromine recovery.

[0030] Further, see Figure 1 and Figure 2 There are multiple second baffles, which are arranged in sequence on the side wall of the discharge box 100 in the vertical direction, and the intervals between two adjacent second baffles are arranged. After the pyrolysis gas enters the discharge box 100, it is first blocked by the first baffle 110 to reduce the rising speed of the pyrolysis gas, and then blocked by the second baffle to further reduce the rising speed of the pyrolysis gas, and the pyrolysis gas passes through the gaps of the second baffles.

[0031] It is understandable that, referring to Figure 1 and Figure 2The second baffle includes a movable block 123, a first movable plate 121 and a second movable plate 122. One end of the first movable plate 121 is hinged to the movable block 123, and the other end of the first movable plate 121 is hinged to the second movable plate 122. The second movable plate 122 passes through the side wall of the discharge box 100, and the movable block 123 is movably arranged on the inner side of the discharge box 100 in the vertical direction. By pulling the second movable plate 122 outside the discharge box 100, the second movable plate 122 drives the first movable plate 121 to rotate, so that the first movable plate 121 gradually approaches the side wall of the discharge box 100, so that the gap between the second baffles gradually increases, and the flow rate of the pyrolysis gas is increased. The second baffle is adjusted by driving the second movable plate 122, which is convenient and quick. It should be noted that the sealing performance can be improved by setting a sealing ring between the second movable plate 122 and the side wall of the discharge box 100.

[0032] It is understandable that, referring to Figure 1 The spray mechanism includes a delivery pipe 210 and a plurality of spray heads 220. The plurality of spray heads 220 are arranged in the delivery pipe 210. The delivery pipe 210 is arranged to be inclined from top to bottom. The delivery pipe 210 is connected to the exhaust port and the separation mechanism respectively. By tilting the delivery pipe 210 from top to bottom, the pyrolysis gas slowly sinks along the delivery pipe 210 after entering the delivery pipe 210, so that the spray water sprayed by the spray head 220 fully condenses the pyrolysis oil in the pyrolysis gas. At the same time, the condensed pyrolysis oil flows into the separation mechanism along the delivery pipe 210, thereby improving the recovery efficiency.

[0033] It is understandable that, referring to Figure 1 The separation mechanism includes a separation tank 310, and the separation tank 310 is provided with a first oil discharge port 311, a second oil discharge port 312 and a third oil discharge port 313, which are arranged in sequence from top to bottom. Pyrolysis oil usually contains light oil, heavy oil and bromine-containing wastewater. After the pyrolysis oil and the spray water enter the separation tank 310, stratification will occur. The light oil, bromine-containing wastewater and heavy oil in the mixed liquid in the separation tank 310 are layered in sequence from top to bottom. By opening the first oil discharge port 311, the light oil is discharged from the first oil discharge port 311, and by opening the second oil discharge port 312, the bromine-containing wastewater is discharged from the second oil discharge port 312. Finally, the heavy oil is discharged from the third oil discharge port 313, so that the bromine-containing wastewater is separated.

[0034] It is understandable that, referring to Figure 1 The separation tank 310 is also provided with an air outlet, which is connected to a fan, and the air outlet sends out the pyrolysis air through the fan. Through the air outlet, the non-condensed pyrolysis gas is sent out of the separation tank 310 and sent to other processing equipment.

[0035] It is understandable that, referring to Figure 1The separation mechanism also includes a first filter tank 320 and a second filter tank 330, which are connected in sequence, and the first filter tank 320 and the second filter tank 330 cooperate to filter oil and suspended matter. The first filter tank 320 contains sand, and after the bromine-containing wastewater enters the first filter tank 320, it is filtered by the first filter tank 320 to remove the suspended matter in the wastewater, and then the wastewater enters the second filter tank 330, and the second filter tank 330 contains a filter element, which absorbs the residual oil in the wastewater, and further removes the residual oil in the wastewater.

[0036] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
