Embodiment 1
[0047] Such as figure 2 Shown, a kind of glyphosate mother liquor treatment device comprises the crystallization tank 1, rotor pump 2, solid-liquid separation device 3, conveying pump 4, incineration device 5 and dosing device 6 that are connected successively; Described crystallization tank 1 is provided with A material outlet 101 and at least two feeding ports 102 , the material outlet 101 is connected to the rotor pump 2 , and any feeding port 102 is connected to the dosing device 6 .
Embodiment 2
[0049] Such as image 3 Shown, a kind of glyphosate mother liquor processing device comprises the crystallization tank 1, rotor pump 2, solid-liquid separation device 3, delivery pump 4, supercritical water oxidation device 7 and dosing device 6 that are connected successively; The crystallization tank 1 is provided with a material outlet 101 and at least two feeding ports 102, the material outlet 101 is connected to the rotor pump 2, and any feeding port 102 is connected to the dosing device 6.
[0050] The working principle of the above-mentioned embodiment 1 and embodiment 2 is: the glyphosate mother liquor with a temperature of about 85-95° C. and sodium pyrophosphate or sodium phosphate are fully mixed in the crystallization tank 1, and the crystallization tank 1 can be provided with its inner wall as required. The scraper 103 in contact with each other prevents the sodium oxide crystals from adhering to the crystallization tank. In order to maintain the glyphosate mother...
Embodiment 3
[0053] The solid-liquid separation device 3 is also connected with a salt discharge device 8, and the salt discharge device 8 includes a self-priming pump 801 and a mobile device 802, and the sodium chloride crystallized out in the solid-liquid separation device 3 is precipitated at the bottom of the solid-liquid separation device 3, automatically One end of the suction pump 801 extends into the bottom of the solid-liquid separation device 3 to suck out the sodium chloride, and the other end is connected to the mobile device 802, and the mobile device 802 can transfer the sodium chloride sucked out by the self-priming pump 801.
