AI Technical Summary
During the chlorination reaction or other reactions, multiple gas materials need to be input into the reactor at the same time, but the prior art requires the installation of multiple intake pipes on the kettle cover, which occupies a large area of the kettle cover and is prone to corrosion of the pipeline.
A combined tetrafluoro-covered silicon carbide dual-channel bottom tube is adopted. The device includes a tetraverse pipe, an outer channel input pipe, an inner channel input pipe and an explosion-proof component. It transports materials simultaneously to the inner and outer channels through the tetraverse pipe, reducing the number of feed pipes on the kettle cover, and reducing the risk of pipeline corrosion through the tetrafluoro component.
It is realized that two different components and different proportions of materials are input simultaneously through the channel port of one reactor kettle cover, reducing the installation area of the channel on the reactor kettle cover and reducing the possibility of pipeline corrosion.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fine chemical equipment, in particular to a combined polytetrafluoroethylene-lined silicon carbide double-channel bottom insert tube. Background Art
[0002] During chlorination reaction or other reaction processes, it is often necessary to pass gaseous materials into the bottom of the kettle through a dip tube to react with the materials in the kettle. During the reaction, two types of gaseous materials may be required. When multiple gaseous materials need to be introduced, it is generally necessary to install multiple air inlet pipes on the kettle cover. However, installing multiple air inlet pipes on the kettle cover may occupy a large area of the kettle cover, which is inconvenient to operate. At the same time, during the kettle reaction process, the temperature in the kettle is too high and the materials are extremely corrosive, which seriously corrodes the steel. This may cause ordinary dip tubes to be unable to be used for a long time. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Embodiment 1:

[0025] Tee pipe 3;
[0026] The external channel input pipe 1 is fixedly connected to the three-way pipe 3;
[0027] The inner channel input pipe 4 is fixedly connected to the tee pipe 3, and the inner channel input pipe 4 is placed in the outer channel input pipe 1;
[0028] The explosion-proof component is connected to the external channel input pipe 1.
[0029] A first flange 301 and a symmetrically arranged second flange 302 are fixedly connected to the tee pipe 3 .
[0030] It should be noted that the inner channel input pipe 4 is a silicon carbide pipe on the market.
[0031] It should also be noted that the three-way pipe 3 is a steel-lined polytetrafluoroethylene pipe available on the market.
[0032] The bottom of the tee pipe 3 is fixedly connected to a reducer pipe 2 via a second flange 302 , and the reducer pipe 2 is fixedly connected to the external channel input pipe 1 .
[0033] The reducer 2 is fixedly connected with a third flange 201 , and the device can be installed on the kettle body through the third flange 201 .

[0035] Reference Figure 2 The pipeline outer lining layer 101 and the pipeline inner lining layer 102 are both polytetrafluoroethylene lining layers. By wrapping the outer channel input pipe 1 with inner and outer layers, the silicon carbide pipe can be effectively prevented from bursting.
[0036] When in use, the input pipe of the steel-lined polyfluoroethylene tee pipe 3 is respectively connected with the silicon carbide inner channel input pipe 4 and the silicon carbide outer channel input pipe 1. The silicon carbide inner channel input pipe 4 and the silicon carbide outer channel input pipe 1 respectively transport materials of different proportions from the two input ports of the steel-lined polyfluoroethylene tee pipe 3, thereby achieving two uses with one port.
[0037] Through the three-way pipe 3 in the device, two materials are simultaneously transported to the inner channel input pipe 4 and the outer channel input pipe 1, and it is no longer necessary to open multiple feeding pipes on the reactor body. Two materials with different components and different proportions can be simultaneously introduced by using a channel opening of the reactor cover, which reduces the channel installation area on the reactor cover. At the same time, the possibility of pipeline corrosion is reduced by the polytetrafluoroethylene components arranged in the device.

[0041] The reducer 2 is provided with a mounting groove 202 , in which a sealing ring 5 is connected, and the top of the sealing ring 5 is in contact with the top of the external channel input pipe 1 .
[0042] The sealing ring 5 is a square gasket.
[0043] Reference Figure 2 , Figure 3 The sealing ring 5 can prevent the silicon carbide tube from bursting due to hard connection.
[0044] It should be noted that the sealing ring 5 is a polytetrafluoroethylene gasket.
