Abstract

The invention relates to a production system of rubber filler. The production system of rubber filler comprises a reaction tank, wherein a material inlet pipe is arranged on the top of the reaction tank, a plurality of catalyst bed layers are arranged sequentially in the reaction tank from top to bottom, and a flow dividing mechanism is disposed above the catalyst bed layers; the flow dividing mechanism is arranged right below the material inlet pipe, and includes a plurality of hollow circular truncated cones, the center positions of the circular truncated cones are the same, and the size ofthe circular truncated cones are gradually enlarged from inside out; a bypass passage is formed between every two adjacent circular truncated cones, tops of the circular truncated cones are connectedto each other through upper connecting members, and bottoms of the circular truncated cones are connected to each other through lower connecting members; and a material outlet pipe is arranged on thebottom of the reaction tank. According to the device, flow diversion and buffer of crude oil can be achieved at the same time, the falling speed of the crude oil can also be affected, so that it is ensured that the crude oil is combined with a catalyst timely and evenly for a hydrogenation reaction, and the possibility of coking is reduced greatly.

Description

technical field

[0001] The invention relates to the technical field of rubber filler production, in particular to a rubber filler production system. Background technique

[0002] As a rubber filler, white oil is more and more widely used in the process of cooperating with rubber. It is an indispensable substance in the rubber industry. The production of white oil is by crude oil normal pressure and vacuum fractionation, solvent extraction and dewaxing. Hydrogenation derived. Hydrofining is an important step in white oil production. By heating the material to a certain temperature and mixing it with hydrogen, the hydrogenation reaction is completed under the action of a catalyst. Hydrofining requires a hydrogenation reactor. The existing hydrogenation The following problems generally exist in the reactor: (1) The hydrogenation process is an exothermic reaction, and the raw material oil is fed from the center of the top of the reactor, and most of them are concentrated in the...

Embodiment Construction

[0021] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0022] see Figure 1 to Figure 5 , the present invention provides a production system for rubber fillers, including a reaction tank 1, the top of the reaction tank 1 is provided with a feed pipe 2, crude oil and hydrogen are mixed and heated to reach the reaction temperature and then transported through the feed pipe 2 In the reaction tank 1, several catalyst beds 3 are sequentially arranged in the reaction tank 1 from top to bottom. After crude oil enters the reaction tank 1, it passes through each section of the catalyst bed 3, layer by layer. Carry out hydrogenation reaction, the top of described catalyst bed 3 is provided with diverter mechanism 4, and described diverter mechanism 4 is positioned at the bottom of described feed pipe 2, and described diver...
