[0032] As shown in Figures 1-6 The principle of the emulsion wastewater high-temperature demulsification concentrated liquid drying waste gas condensate separation equipment provided by the embodiment is as follows: when the device is used, the emulsion wastewater drain pipe is fixedly connected to the emulsion wastewater injection pipe 24, so that the emulsion wastewater can smoothly enter the emulsion wastewater reaction cavity 20. In this process, the height of the injected wastewater can be observed through the transparent observation plate window 27.

[0033] After the emulsion wastewater injection is completed, the several electric heating module rods 18 rapidly heat the emulsion wastewater in the emulsion wastewater reaction cavity 20 to perform high-temperature demulsification on the emulsion wastewater.

The separated gas enters the filter drying box 14 under the action of the first air pump 17.

[0036] The gas entering the filter drying box 14 passes through the several adsorption filter plates 16. The adsorption filter plates 16 adsorb and filter the gas. The filtered gas passes through the several adsorption filter plates 16 and is dried under the action of the baking purification lamp 15. The purified and dried air is drawn into the compressed gas tank 28 under the action of the second air pump 30 and is temporarily stored. When needed, the device can be connected to another device through the cooperation of the gas discharge pipe 31 and the second electric control switch valve 32 to process or utilize the gas in the storage gas tank 28.

[0037] In use, the sealed door 35 should be opened periodically and the adsorption filter plates 16 in the filter drying cabinet 14 should be cleaned and replaced, and the arched sealed cover 19 should be opened periodically and the flocculation stored in the flocculation storage box 22 should be removed.
