Abstract

The utility model discloses a reaction kettle cooling system with a structural improvement. An upper static ring and a lower static ring respectively, hermetically and fixedly arranged on an upper sealing box body and a lower sealing box body respectively come into sealed contact with moving rings at both ends of a moving ring module; both ends of a sealing barrel are respectively, hermetically and fixedly connected with the upper sealing box body and the lower sealing box body; a sealing cavity is formed among the upper sealing box body, the lower sealing box body, the upper static ring, the lower static ring, the moving ring module and the sealing barrel; the upper sealing box body and the lower sealing box body are respectively provided with an outlet channel and an inlet channel which are used for enabling the sealing cavity to be communicated with the outside; and the inlet channel is correspondingly located at the lower section of the outer side wall in the circumferential direction of the lower static ring. In the reaction kettle cooling system, the inlet channel of a cooling medium is located at the lower section in the circumferential direction of the lower static ring, so that the lower static ring can be fully cooled, and thereby, heating components in a whole reaction kettle can be fully cooled; and simultaneously, impurities in the cooling medium also can be deposited into an annular space at the position of an inlet, so that the components in the reaction kettle are prevented from abrasion and the service lives of the components in the reaction kettle are ensured.

Description

Structure improved reactor cooling system

Technical field

The utility model relates to a kind of reactor cooling system, particularly a kind of structure improved reactor cooling system.

Background technology

At present, the entrance location of the cooling system of reactor all is positioned at stationary ring upper end down, directly is communicated with seal chamber, cooling medium is without the outside of following stationary ring circumferencial direction, this causes, and the stationary ring cooling is insufficient down, and heat is difficult to distribute, and also just makes down stationary ring short service life.

The utility model content

In order to remedy above deficiency, the utility model provides a kind of structure improved reactor cooling system, and this structure improved reactor cooling system makes the cooling of reactor inner part fully.

The utility model for the technical scheme that solves its technical problem and adopt is: a kind of structure improved reactor cooling system, comprise the rotating ring module, on, following stationary ring, on, lower seal casing and sealed cylinder, to use direction to be benchmark, on, following stationary ring sealing and fixing respectively is located at, on the lower seal casing, on, following stationary ring contacts with the rotating ring sealing at the two ends up and down of rotating ring module respectively, two ends are respectively with last about the sealed cylinder, the lower seal box sealing is connected, on, the lower seal casing, on, following stationary ring, form a seal chamber between rotating ring module and the sealed cylinder, last seal case is provided with an exit passageway that the sealing cavity is in communication with the outside, the lower seal casing is provided with an intake channel that the sealing cavity is in communication with the outside, described this intake channel correspondence is positioned at stationary ring circumferencial direction lateral wall lower section down, the cooling liquid inlet position is low, guarantees that stationary ring also can be cooled to fully down.

As further improvement of the utility model, described stationary ring circumferencial direction lateral wall down forms the part of intake channel madial wall, and cooling medium directly contacts with following stationary ring lateral wall, guarantees that the stationary ring cooling is more abundant down.

As further improvement of the utility model, form a loop space between described lower seal casing and the following stationary ring outer wall, this annulus is communicated with the intake channel and the seal chamber of lower seal casing respectively, short grained impurity can enter deposition in the annulus when guaranteeing fully cooling like this, prevents abrasion sealing device.

The beneficial effects of the utility model are: the utility model moves down into down fragment position under the stationary ring circumferencial direction by the intake channel with cooling medium, guarantee that stationary ring also can be sufficiently cooled down, thereby entire reaction still internal heat generation components and parts are all cooled off fully, also the impurity in the cooling medium can be deposited in the annulus of import department simultaneously, the interior components and parts of the reactor that prevents to wear and tear, the service life of components and parts in the assurance reactor.
