[0002] The polyether reactor is the main equipment for producing polyether at present, but the current reactor has a small arc on the top and a spray system that sprays the reaction material from the center to the surroundings, so that the reaction material is sprayed on the peripheral wall of the reactor. Flowing along the surrounding wall to the bottom of the reactor makes the gas-liquid phase dispersion of the reaction material insufficient, thus affecting the overall reaction efficiency

Embodiment Construction
[0012] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 and figure 2 The high-efficiency polyether reactor shown comprises a cylindrical closed reaction vessel 1, and the upper end of the cylindrical reaction vessel 1 is connected with a hemispherical head whose diameter is greater than the diameter of the cylinder through a large and small head, so that the reaction vessel 1 The upper part forms a quasi-spherical reaction chamber structure with a large volume, which serves as a relatively independent gas-liquid phase contact chamber.
[0014] The upper end surface of the reaction vessel 1 is provided with a circulating liquid inlet 2 and a reaction material inlet 3, and the circulating liquid inlet 2 and the reaction material inlet 3 can be opened more; a circulating liquid injection device 4 and a reaction material injection device 5 are arranged inside ...

The invention discloses an efficient polyether reactor, which comprises a round tubular sealed reaction container, a feeding system and a discharging system, wherein the feeding system comprises a circulation liquid inlet, a reaction material inlet, a circulation liquid spraying device and a reaction material spraying device; the circulation liquid inlet and the reaction material inlet are formedin the upper end surface of the reaction container; the circulation liquid spraying device and the reaction material spraying device are arranged inside the reaction container and respectively communicate with the circulation liquid inlet and the reaction material inlet; each of the circulation liquid spraying device and the reaction material spraying device comprises a plurality of spraying openings in scattered arrangement in the inner wall of the upper part of the reaction container; the spraying directions of the spraying openings are concentrated. The efficient polyether reactor has the advantages that firstly, the spraying openings spray towards one position, so that the circulation liquid and the reaction materials can realize sufficient contact; a mixed material spraying pipe realizes the blanking from one side and realizes the stirring effect on the lower part liquid, so that the reaction is more thorough; secondly, when the materials are discharged out from the discharging system and the reaction requirements are not reached, the discharging system and the circulation liquid inlet are communicated; the materials can be introduced again for circulation reaction.
Description
technical field [0001] The invention relates to the field of chemical machinery, in particular to a high-efficiency polyether reactor. Background technique [0002] The polyether reactor is the main equipment for producing polyether at present, but the current reactor has a small arc on the top and a spray system that sprays the reaction material from the center to the surroundings, so that the reaction material is sprayed on the peripheral wall of the reactor. Flowing along the surrounding wall to the bottom of the reactor makes the gas-liquid phase dispersion of the reaction material insufficient, thereby affecting the overall reaction efficiency. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the background technology, the present invention discloses a polyether reactor that reacts more efficiently and thoroughly, thereby reducing the number of cycles of circulating liquid and improving reaction efficiency.
