Embodiment 1

[0025] Such as figure 1 As shown, Embodiment 1 of the present invention provides an auxiliary structure for a mechanical seal balance tank used on a reactor. The mechanical seal balance tank auxiliary structure used on the reactor includes a reactor 1 and a balance tank 2, the balance tank 2 is communicated with the still body 10 of the reactor 1 through the pressure introduction pipe 3, and the pressure introduction pipe 3 is connected with the reactor 1 at the same time. A feed tube (not shown) communicates. As known to those skilled in the art, the communication between the pressure guiding pipe 3 and the kettle body 10 means that the pressure guiding pipe 3 communicates with the upper part of the kettle body 10 so as to introduce the pressure of the gas phase in the kettle body 10 into the balance tank 2 . In other words, the position where the pressure introduction pipe 3 communicates with the kettle body 10 is set at a position where the pressure of the gas phase in the...

Embodiment 2

[0036] Embodiment 2 is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that the balance tank of Embodiment 2 is a hydraulic cylinder, and a piston is arranged in the hydraulic cylinder, and the piston divides the hydraulic cylinder into a sealed liquid chamber. The connected first chamber communicates with the kettle body and the second chamber communicates with the kettle body, wherein the second chamber communicates with the kettle body and the feeding pipe simultaneously through a pressure introduction pipe. That is, applying the method of introducing pressure simultaneously from the feeding pipe of the reactor and the gas phase in the reactor body to the existing piston balance tank can also achieve the purpose of preventing water vapor and reagents in the reactor body from entering the pressure introduction pipe.

[0037] The above-mentioned reaction kettle in the second embodiment is a tetrafluoroethylene polymerization rea...

Abstract

The invention relates to the field of reactor sealing technology, and especially relates to a mechanical sealed balance tank auxiliary structure applied to a reactor. The auxiliary structure comprises a reactor (1) and a balance tank (2). The balance tank (2) is communicated with the reactor body (10) of the reactor (1) through an impulse pipe (3). The impulse pipe (3) is communicated with the feed pipe of the reactor (1) at the same time. The balance tank (2) has a cavity (20). The cavity (20) is communicated with the sealing liquid inlet (401) of a sealing liquid cavity (40) through a first pipeline (51) and is communicated with the sealing liquid outlet (402) of the sealing liquid cavity (40) through a second pipeline, and the cavity (20), the first pipeline (51), the sealing liquid cavity (40), and the second pipeline form a sealing liquid loop. Pressure is applied on the feed pipe of the reactor and gas phase in the reactor body (10) at the same time to make the pressure in the impulse pipe (3) be slightly greater than the pressure in the reactor body (10) so that the water steam and reagents in the reactor body (10) will not enter the impulse pipe (3).

Description

technical field [0001] The invention relates to the technical field of sealing of reactors, in particular to a mechanical seal balance tank auxiliary structure used on reactors. Background technique [0002] A reaction kettle used to prepare polymer compounds is generally composed of a kettle body, a kettle cover, a jacket, an agitator, a transmission device, a shaft sealing device, and a support, among which the shaft sealing device generally adopts a mechanical seal. At present, the auxiliary structure of the mechanical seal balance tank used for the preparation of polymer compounds, especially the tetrafluoroethylene polymerization reactor, is mostly a piston structure. [0003] Patent No. CN203737203U discloses a mechanical seal balance tank auxiliary structure used on a reactor, including a reactor and a hydraulic cylinder connected to the reactor, a sealing platform is installed at the opening end of the reactor, and a sealing liquid is arranged in the sealing platform...
