Description

Technical Field

[0001] The utility model relates to an organic silicon byproduct processing device, in particular to a pulp residue processing device. Background Art

[0002] In the synthesis of organosilicon monomers, methyl chloride as a raw material reacts with metal silicon powder under the action of a catalyst. This reaction is a gas-solid contact exothermic reaction. The reaction rate of methyl chloride gas and silicon powder solid is affected by the particle size of silicon powder, the amount of catalyst used and the temperature of methyl chloride. At present, in the production of organosilicon monomers, a large amount of incompletely reacted small-particle silicon powder and impurities are taken out of the fluidized bed together. After cyclone separation and washing separation in the post-system, some unreacted silicon powder and catalyst particles are combined with high-boiling substances in organosilicon to form organosilicon slurry.

[0003] When domestic silicone enterprises deal with the silicone slurry, the common practice is to hydrolyze and deactivate the silicone slurry, but this will produce a large amount of acid-containing wastewater and black hydrolyzate, greatly increasing the operating cost. When foreign silicone enterprises deal with the silicone slurry, they directly transport the slurry to the rotary kiln for incineration, which will also produce a large amount of waste gas and increase the cost of waste gas treatment.

[0022] The technical solution of the utility model is further described below in conjunction with the embodiments and drawings.

[0023] like Figure 1 As shown, the slurry treatment device of the utility model may include components such as a conveying pump 1, a centrifuge 2, a solid phase collection tank 3, a liquid phase collection tank 4 and a condenser 5, so that the slurry treatment device of the utility model can treat the slurry, wherein the slurry can be silicone slurry.

[0024] The delivery pump 1 is used to deliver pulp and slag; in this embodiment, the interior of the delivery pump 1 is made of acid-resistant and wear-resistant materials, so that the pulp and slag will not corrode and damage the delivery pump during delivery. In a preferred embodiment, the delivery pump 1 can be equipped with an automatic flushing system, so that the delivery pump can be cleaned in time after the pulp and slag are delivered.

[0025] The centrifuge 2 is used to receive the pulp delivered by the delivery pump 1 and separate the pulp into solid phase and liquid phase. The centrifuge 2 of the utility model adopts an improved screw extruder. Specifically, the centrifuge 2 of this embodiment can include: a housing 21, a barrel 22, a screw rod 23 and other components.

[0026] The shell 21 includes a solid-phase material outlet and a liquid-phase material outlet. In this embodiment, the liquid-phase material outlet is located at one end of the shell 21 , and the solid-phase material outlet is located at the other end of the shell 21 .

[0027] The cylinder 22 is arranged in the shell 21, and a through hole is formed on the cylinder 22. The liquid phase material is discharged to the outside of the cylinder 22 through the through hole and is collected by the shell 21; the solid phase material is discharged through the other end of the cylinder 22; wherein, one end of the cylinder 22 is closed, and one end of the cylinder 22 corresponds to one end of the shell 21, and accordingly, the other end of the cylinder 22 corresponds to the other end of the shell 21.

[0028] The screw rod 23 is rotatably disposed on the housing 21 , and the screw rod 23 is located in the barrel 22 , and the outer peripheral surface of the screw rod 23 is matched with the inner surface of the barrel 22 .

[0029] In a preferred embodiment, the spiral rod 23 includes: a rod component and a spiral blade; the rod component is rotatably arranged on the shell 21; wherein the rod component is provided with a center hole along the axial direction, and the center hole is formed as a pulp conveying channel; that is, the center hole is connected to the conveying pump 1, so that the pulp conveyed by the conveying pump 1 can enter the interior of the centrifuge 2 through the center hole.

[0030] The spiral blade is arranged on the rod component; preferably, the spiral blade is spirally arranged on the outer surface of the rod component, wherein a through hole is opened on the outer peripheral surface of the rod component, and the pulp residue is discharged to the area between the rod component and the cylinder 22 through the through hole of the rod component, thereby, when the spiral rod 23 rotates along a preset direction, it can squeeze the pulp residue and realize the separation of solid phase matter and liquid phase matter.

[0031] In this embodiment, along the direction from one end to the other end of the spiral rod 23, the outer diameter of at least part of the spiral blade gradually decreases, so that the centrifuge of this embodiment has a better separation effect. Correspondingly, along the direction from one end to the other end of the barrel 22, the outer diameter of at least part of the barrel 22 gradually decreases, so that the inner surface of the barrel 22 can match the outer peripheral surface of the spiral rod 23.

[0032] In this embodiment, the centrifuge 2 can be made of acid-resistant substrate material, the volume proportion of the solid phase of the slurry is 30-50% Vol; the speed of the screw rod 23 of the centrifuge 2 is 800-1200 rpm / min; the flow rate of the delivery pump 1 is approximately 1-3m 3 / h.

[0033] Therefore, the pulp and slag treatment device of this embodiment can separate more than 80% of the liquid phase after separation by the centrifuge 2, thereby reducing the treatment amount of hazardous waste; at the same time, 50% of the recovered liquid phase material can be cracked into organic silicon monomer for utilization, thereby increasing the yield of organic silicon monomer; and, the continuous operation of the centrifuge 2 can be ensured by the delivery pump 1, thereby reducing the production cost.

[0034] The solid phase collection tank 3 is used to collect the solid phase separated by the centrifuge 2; the liquid phase collection tank 4 is used to collect the liquid phase separated by the centrifuge 2. Preferably, the solid phase collection tank is made of acid-resistant substrate material; the high-boiling material collection tank is made of ordinary carbon steel; wherein the organosilicon slurry is a liquid-solid mixture.

[0035] A condenser 5 is provided between the centrifuge 2 and the liquid phase collecting tank 4, so that the liquid phase material entering the liquid phase collecting tank 4 has a lower temperature.

[0036] The use of the slurry residue treatment device of this example can effectively reduce the amount of organosilicon slurry residue, recover high-boiling substances of organosilicon, reduce hazardous solid waste of organosilicon, reduce environmental hazards, and reduce costs.
