Description

Technical Field

[0001] The utility model relates to the technical field of hazardous waste hydrolysis devices, in particular to a hazardous waste hydrolysis device with a scum cleaning function. Background Art

[0002] Monomer conversion residual liquid is a waste liquid in the chemical industry of a hazardous waste hydrolysis device with the function of cleaning scum. It is usually a waste liquid generated in the monomer conversion process. Monomer conversion is the process of converting simple monomer molecules into more complex compounds. Monomer conversion residual liquid is mainly produced in polymerization reactions or other chemical transformation processes. When monomers react to generate polymers or other compounds, some by-products or incompletely reacted residual substances will be produced. These by-products or residual substances usually exist in the form of liquids and are called monomer conversion residual liquids. In order to decompose the organic matter in the residual liquid into simpler compounds for further processing or recycling, water is added to the residual liquid, and a hydrolysis reaction occurs under alkaline conditions.

[0003] When the monomer conversion residual liquid reacts with water, certain components in the monomer conversion residual liquid react chemically with water to produce scum. The scum may clog pipes or equipment and pollute the environment. Therefore, the staff wear protective clothing to remove the scum produced by the reaction.

[0004] However, during the manual cleaning process, long cleaning operations will make workers physically tired and difficult to continue, thus affecting work efficiency and possibly resulting in poor cleaning quality. If the cleaning work is not thorough, uncleaned scum will clog pipes or equipment, causing production delays or interruptions. Utility Model Content

When the water level rises to a suitable position, the motor is turned off. Water pump and diaphragm pump, when the hazardous waste in the reaction tank is hydrolyzed to produce scum, the rotating stirring blades scrape the scum out of the reaction tank through the opening and drop it into the previously prepared transport basin; when the hazardous waste reacts with water to produce acidic gas, the acidic gas enters the spray tower through the outlet pipe, and the acidic gas is washed with alkali in the spray tower, and an acid-base neutralization reaction occurs, and the discharge meets the standard; when the scum in the reaction tank is completely scraped out, shut down the motor, water pump and diaphragm pump, and open the drain valve, and the hydrolyzed hazardous waste is discharged through the drain pipe.

[0023] The implementation method of this embodiment is as follows: when the hazardous waste needs to be hydrolyzed, firstly, a slag collecting basin is placed just below the outlet end of the drainage tank 13, and then the hazardous waste is added to the reaction tank 1 through the hazardous waste pipe 54, and then the water pump 522, the diaphragm pump 512 and the motor 6 are turned on, and the valve 1 511 and the valve 2 521 are opened. Under the action of the water pump 522 and the diaphragm pump 512, the water in the water tank 4 and the alkali liquid in the alkali liquid tank 2 enter the reaction tank 1 through the water adding pipe 52 and the alkali liquid pipe 51 respectively.
