Problems solved by technology

The formation of a large number of dense lumps, which on the one hand causes the formed lumps to stick to the walls of the reactor, resulting in product loss and the need to clean the walls
On the other hand, the formation of dense lumps makes the contact between gas and solid uneven, and the properties of the obtained products are also uneven.
[0005] Another example, adopt the reaction method of existing gas and solid particle, because solid particle is a stationary fixed bed, both ends must be filled with stuffing, so just caused the inconvenience of solid particle dismounting, also to solid particle and The separation of filling materials is not only labor-intensive, but also the transportation of solid particles and the discharge from the reaction equipment are not easy to automate
In particular, when the solid particles are ultra-fine powder materials with corrosive and pungent odors, it is easy to pollute the environment and damage the health of operators due to inconvenient loading and unloading.
[0006] It is also because the solid particles are a static fixed bed, the gas reacting with the solid particles or the gas carrying the substance reacting with the solid particles must be a flowing gas, so that the gas reacting with the solid particles, as the gas carrying the reaction substance The consumption of carrying gas and reactive substances is large, containing unreacted gas and waste gas generated by reaction, or containing the carrying gas as carrying reactive substances, reactive substances that have not reacted with solids, and waste gas substances generated after reaction. very big

Embodiment approach 1

[0019] The first specific embodiment of the present invention is as follows figure 1 shown. Described reaction equipment comprises a reactor 1, a feed port 2 and a gas outlet 3, also has a stirrer 4 inside the reactor 1, and wherein, a gas-solid separator 5 is installed on the gas outlet 3, gas The hole diameter and porosity of the holes contained in the solid separator 5 ensure that the gas can pass through but the solid particles cannot pass through. The stirring rod of the stirrer 4 stretches out of the reaction kettle 1, and the place where the stirring rod contacts the reaction kettle 1 is airtight, so that the reaction kettle 1 is not connected to the outside world.

[0020] When carrying out the reaction of gas and solid particles, load the solid particles from the feed port 2, start the agitator 4, and add the gas that reacts with the solid particles or the material that can generate the gas that reacts with the solid particles, and the feed port 2 And air outlet 3 ...

Embodiment approach 2

[0022] The second specific embodiment of the present invention is as figure 2 shown. The reaction device includes all components of the first embodiment, and also includes an air inlet 6 . The air inlet 6 can be located at any position of the reactor 1 , preferably, the feed inlet 2 and the gas outlet 3 are located at the upper part of the reactor 1 , and the air inlet 6 is located at the lower part of the reactor 1 . The air inlet 6 is used to add gas or gasifiable material that reacts with solid particles. With the gas inlet 6, the gas or the substance that can generate the gas reacting with the solid particles is fed through the gas inlet 6, and the feed inlet 2 is specially used for adding the solid particles, and the operation is more convenient.

[0023] During the reaction between the gas and the solid particles, the solid particles are loaded from the feed port 2, the agitator 4 is started, and the feed port 2 and the gas outlet 3 are sealed. Add the gas that react...

Embodiment approach 3

[0025] The third specific embodiment of the present invention is as image 3 shown. The reaction equipment includes all the components of the second specific embodiment, and a gas distributor 9 is installed on the top of the air inlet 6, and the top of the gas distributor 9 is on a plane or at the height of the bottom of the reactor 1. On the plane where the bottom of the reactor 1 is located. The function of the gas distributor is to enable the gas to enter the reaction kettle 1 continuously and evenly, and at the same time, ensure that solid particles do not enter the pipeline connected to the air inlet 6 .

[0026] When carrying out the reaction of gas and solid particles, the solid particles are loaded from the feed port 2, the feed port 2 and the gas outlet 3 are sealed, the agitator 4 is started, and the feed port 2 is sealed. Add the gas that reacts with the solid particles or the material that can generate the gas that reacts with the solid particles from the gas inl...

Abstract

The present invention relates to a method for making gas and solid granules produce reaction. Said method includes that making gas be contacted with solid granules, the described contact is simplemented in a reaction equipment, said reaction equipment comprises a reaction kettle, a material inlet and a gas outlet, in which the interior of reaction kettle is equipped with a stirring device, and onthe gas outlet a gas-solid separator is mounted. Said invention also provides the connection mode of them and working principle of said method and reaction equipment.

Description

technical field [0001] The present invention relates to a method for reacting fluid with solid particles, more particularly to a method for reacting gas with solid particles. Background technique [0002] The method for existing gas and solid particle reaction comprises that gas is contacted with solid particle, and described contact is carried out in a reaction device, and described reaction device is made of a reaction tube (or be called reaction kettle) and is positioned at the reaction tube two ends and carries out. It consists of a gas port and a gas outlet, and the solid particles are a solid bed of solid particle materials. When the reaction between gas and solid particles is carried out, a fixed bed of solid particle materials is placed in the middle of the reactor, and the two ends are filled with fillers such as ceramic rings or quartz materials to ensure that the solid particles are fully filled and fixed in the reaction. The middle section of the device, and ens...
