Hereinafter, will be explained in the gas solid reactor provided by the present application for being used to prepare molecular sieve and use referring to attached drawing
In the equipment for preparing molecular sieve.
Firstly, the application provides a kind of gas solid reactor for being used to prepare molecular sieve referring to Fig. 2.The gas solid reactor packet
Conveying room, mixing chamber and unloading house are included, conveying room is for inputting material to be reacted to gas solid reactor, and mixing chamber is for mixing
Material, outside of the unloading house for the material discharge reactor after reacting.It should be noted that the gas-solid of the application is anti-
Conveying room, mixing chamber and the unloading house for answering device are the interconnected structures in space, and why the structure not mutually separated divides
It is named at three chambers, is the function in order to distinguish each chamber.In addition, can also illustrate below, in gas-solid reaction
When device works, conveying room and unloading house are stationary state, and mixing chamber is rotary state.
Specifically, feed pipe 1 and air inlet pipe 2 are provided on conveying room, molecular sieve enters gas-solid reaction by feed pipe 1
Inside device, SiCl4Gas is entered inside gas solid reactor by air inlet pipe 2, wherein is distinguished by feed pipe 1 and air inlet pipe 2 defeated
Enter molecular sieve and SiCl4The feeding structure and air intake structure of gas can there are many kinds of modes, as shown in Fig. 2, the end of feed pipe 1
Mouth can stretch to mixing chamber, so that molecular sieve is directly entered mixing chamber, while the port of air inlet pipe 2 is located at conveying room, but this
Apply without being limited thereto, the port for being also possible to feed pipe 1 is set to the top of conveying room, and the port of feed pipe is formed as winnowing with a dustpan
