Embodiment 1

[0041] Example 1: A chemical reactor based on forward osmosis, such as figure 1 As shown, including raw material tank 1, reaction circulation tank 2, ultrafiltration tank 3, forward osmosis tank 4 and finished product tank 5, raw material tank 1 leads to reaction circulation tank 2, and forward osmosis tank 4 is connected with regeneration tank 6, regeneration tank 6 The extraction solution is regenerated by reverse osmosis, and the extraction solution in the forward osmosis tank 4 is supplemented, and the forward osmosis tank 4 leads to the finished product tank 5 and the reaction circulation tank 2 respectively;

[0042] The reaction circulation tank 2 includes a first addition port 201, a second addition port 202, an upper addition port 203 and a discharge port 204, the first addition port 201 is communicated with the raw material tank 1, and the upper addition port 203 is used for adding non-fluid raw materials and catalysts Equal a small amount of raw materials, the disch...

Embodiment 2

[0058] Example 2: The only difference between Example 2 and Example 1 is that the membrane material of the forward osmosis membrane is a solvent-resistant membrane material, and the preparation method of the solvent-resistant membrane material includes the following steps:

[0059] Step 1: take the PP film and soak the PP film with an organic solvent for 30min;

[0060] Step 2: take clean water to clean and soak the PP film for 10 minutes, take a 2% concentration of polyvinyl alcohol solution, and soak the PP film in a 2% concentration of polyvinyl alcohol solution for 30 minutes;

[0061] Step 3: take out the PP film, and soak the PP film in a 1% citric acid solution for 5min;

[0062] Step 4: Take out the PP film and drain the liquid on the surface, and add MPD aqueous phase solution with a concentration of 7% wt / v on the surface. After 10 minutes, take out the PP film, and use a rubber roller to remove the residual MPD water on the surface of the PP film. phase solution; ...

Abstract

The chemical reactor comprises a raw material tank, a reaction circulation tank, an ultrafiltration tank, a forward osmosis tank and a finished product tank, the raw material tank leads to the reaction circulation tank, the forward osmosis tank is connected with a regeneration tank, and the regeneration tank is used for regenerating an extracting solution and supplementing the extracting solution in the forward osmosis tank; the forward osmosis tank is communicated with the finished product tank and the reaction circulation tank respectively; the reaction circulating tank is communicated with a first three-way valve, the first three-way valve is respectively connected with a first conveying pipe and a second conveying pipe, the first conveying pipe leads to the ultrafiltration tank, the second conveying pipe leads to the forward osmosis tank, the osmosis outlet is connected with a second three-way valve, the second three-way valve is respectively connected with a third conveying pipe and a fourth conveying pipe, and the third conveying pipe leads to the finished product tank; according to the present invention, with the arrangement, the flow direction of the material liquid can be adjusted according to the chemical reaction requirements so as to adapt to the requirements of different reaction types, and the versatility of the chemical reactor is improved.

Description

technical field [0001] The invention relates to the field of chemical reaction devices, in particular to a chemical reactor based on forward osmosis. Background technique [0002] Existing reactors for water treatment, such as MBR membrane bioreactors, generally refer to wastewater treatment processes that combine selective osmosis membranes with biological processes. The disadvantage of the MBR method is the high cost of microbial culture, installation and operation and maintenance costs including cleaning and sludge control, and membrane replacement. Membrane separation processes currently applied to the MBR method are limited to microfiltration and ultrafiltration, other processes in which membranes are used to support biomass and facilitate gas transfer to biofilms or to extract ions or water through transmembrane osmotic pressure / vapor pressure differentials, have not been reach the commercial development stage. [0003] At present, the Chinese Patent Publication No. ...
