Wastewater polycondensation reaction kettle

Abstract

The invention relates to the technical field of reaction kettles, and discloses a wastewater polycondensation reaction kettle which comprises a first polycondensation reaction kettle, the bottom of the first polycondensation reaction kettle is sleeved with a sealing plate, and the bottom of the sealing plate is fixedly connected with a mounting plate; the bottom edge of the mounting plate is fixedly connected with the bottom of the first polycondensation reaction kettle through a plurality of bolts. When the water quantity on the circular plate is increased, the connecting ropes on the fixing rods can enable the fixing grating rods to deform, so that the circulation space can be further increased, and the arrangement has the advantages that when the water flow is gradually increased, the circular plate can gradually move downwards in the net sleeve, and in the moving process, the net flow can be gradually adjusted; in this way, the situation that in the filtering process, the water pressure above is too large due to blockages can be avoided, the net flow can be automatically adjusted, the blocking situation is avoided, and the water flow can be adjusted to adapt to the reaction speed in condensation polymerization.

Description

technical field [0001] The invention relates to the technical field of reactors, in particular to a wastewater polycondensation reactor. Background technique [0002] Polycondensation reactor is the main equipment for preparing polymer compounds. It is generally a vertical cylindrical autoclave with a jacket so that steam or cold water can be introduced for heating or cooling. Used for emulsion polymerization, there is a stainless steel horizontal paddle stirrer, which is driven by a motor through a transmission and a reducer. The outer wall of the kettle is usually made of carbon steel, lined with stainless steel, and also lined with enamel. During polymerization, it can be produced batchwise in a single tank, or in series with continuous production in multiple tanks. The polymerization reactants enter the upper part of the next tank from the lower part of one tank. The kettle is equipped with temperature, pressure and other instruments, as well as inlet and outlet port...

AI Technical Summary

Problems solved by technology

[0004] When the waste water produced in polyester production is subjected to polycondensation reaction, since the waste water contains impurity particles in production, the particles in the polycondensation reaction will affect the effect of the polycondensation reaction, making the product phase of the polyester production product worse, However, when the wastewater in the polyester production enters the reactor, it is difficult to control the water flow after the wastewater enters concentratedly, which will cause incomplete reaction. Moreover, when the flow is controlled in the existing polycondensation reactor, the internal impurity removal efficiency will also be affected
