Problems solved by technology

[0003] The invention provides a method for recovering formaldehyde wastewater capable of realizing the recovery of formaldehyde wastewater, and solves the problem that the existing method does not realize the recovery and utilization of formaldehyde wastewater
[0004] The present invention also provides a methyl etherified amino resin formaldehyde waste water recycling device which has a large reversing range, is convenient to open the cover on the feeding port, and can change the height of the stirring blade according to the height of the material in the container, which solves the problem of the existing reaction kettle. When used for the recovery of formaldehyde wastewater, if the direction of the feed port and the direction of the feed pipe cannot be adjusted to the same situation, it is necessary to make an elbow to change the direction, and it is not possible to efficiently process the material when the height of the material changes. Stirring will not cause the phenomenon of idle stirring blades and inconvenience when opening the lid

Abstract

The invention relates to the technical field of methoxylated amino resin wastewater treatment. The invention provides a methoxylated amino resin formaldehyde wastewater recovery method capable of recovering formaldehyde wastewater, which solves the problem that the existing process can not recover formaldehyde wastewater. The invention also provides a methoxylated amino resin formaldehyde wastewater recovery device, which has wide reversing range, is convenient for opening the cover on the feed port and can change the height of stirring blades according to the height change of the material in the container. The device solves the following problems: when the existing reaction kettle is used for recovering formaldehyde wastewater, the reversing needs to be carried out by manufacturing an elbow if the direction of the feed can not be adjusted to be identical to the direction of the feed pipe, and the feed port can not be aligned with the material if the material height changes. The device comprises a container and a stirrer, wherein a feed port of the container is provided with an adjustable-direction feed pipe, the feed pipe is provided with a pull-rod-bearing cover, the height of stirring blades of the stirrer is adjustable, and the motor is provided with a connecting terminal.

Description

technical field [0001] The invention relates to the technical field of methylated amino resin wastewater treatment, in particular to a method and equipment for recovering methylated amino resin formaldehyde wastewater. Background technique [0002] In the production process of methyl etherified amino resin, there is a methanol recovery process. After rectification, the recovered methanol will produce 90% methanol and about 10% formaldehyde waste water. The production of formaldehyde waste water is the biggest source of pollution in the entire production of methyl etherified amino resins. Direct discharge will pollute the water quality around the factory greatly, endangering the environment and the surrounding human health. At present, it is processed by chemical reaction, and waste utilization has not been realized. Contents of the invention [0003] The invention provides a methyl etherified amino resin formaldehyde wastewater recovery method capable of realizing the re...
