Abstract

The invention relates to the field of chemical technology and can be used in the chemical and microbiological industries in order to increase productivity. The reactor contains a vertically mounted housing with connections for input and output of the finished product. Inside the case there is a drain pocket with a sloping bottom, coaxially installed a cylinder for supplying the reaction mixture, inside of which are placed vortex elements. On the upper section of the cylinder there is a conical nozzle, with the smaller base facing upwards. Inside the nozzle, on its axis, there is a product collection pipe connected to the product outlet pipe, with the upper section of the pipe located below or flush with the upper section of the conical nozzle. In the lower part of the drain pocket holes are made, and it is connected through a pipeline and a valve to the outlet nozzle. The top cut of a drain pocket is established above the top cut of a conic nozzle. The product collection pipe is installed obliquely to its axis of the gutter, some ends of which are installed at the cutoff level of the product collection pipe, while others come out of the drain pocket. 1 hp f-ly, 2 ill.

Description

The invention relates to chemical technology and can be used in the chemical, microbiological industry.

The purpose of the invention is to increase productivity by reducing the overshoot of unreacted reagents.

FIG. 1 shows the reactor, general view, longitudinal section; in fig. 2 is a section A-A in FIG. one.

The reactor contains a vertically installed housing 1 with nozzles input 2 and 3 and nozzles 4 and 5 output of the finished product. Inside the case there is a drain pocket 6 with a sloping bottom. Coaxially, it is equipped with a cylinder 7 supplying the reaction mixture, inside of which vortex elements 8 are placed. At the upper section of cylinder 7

installed conical nozzles 9, with a smaller base facing upwards. Inside the nozzle 9 on its axis there is a product collection pipe 10 connected to the product outlet 4, the upper section of the pipe located below or flush with the upper section of the conical nozzle 9. In the lower part of the drain pocket 6, holes 11 are made. Lower part of the drain pocket 6 is connected through a pipeline and valve 12 with the outlet 5 output. The upper cut of the drain pocket 6 is installed above the upper cut of the conical nozzle 9. On the product collection pipe 10, are installed obliquely to its axis of the groove 13, some ends of which are installed at the level of the cut of the product collection pipe 10, while others exit the drain pocket 6.

The reactor operates as follows.

The reactants through pipes 2 and 3 enter the housing 1, where mass transfer processes take place, the finished product together with the reaction solution rises up and enters the cylinder 7, passes through the vortex elements 8 and rises up, while the liquid acquires the rotational motion. Due to the rotation, the reaction mass stratifies in density, with the passage of the conical nozzle 9, the rotational speed increases as the total flow radius decreases (the cone converges) and the process of separation occurs more intensively. The lighter end product of the reaction is collected near the outer walls of the product collection pipe 10, is poured into it and through pipe 4 is removed from the housing 1. More severe reaction components and by-products (tar products) are poured through the edges of the nozzle 9 and fall into the drain pocket 6 in which the most severe by-products are collected and removed through the pipeline with the valve 12 and the nozzle 5 from the housing 1, and the unreacted solution through the holes 11 enters the housing 1 where the reaction ends. The product from the interface is discharged along the grooves 13 to the product collection pipe 10.

In the proposed reactor, most of the reaction solution is separated.

from the product and return to the reactor, while at the same time the by-products are removed from the reactor.
