Description

technical field

[0001] The invention relates to a descaling and separation component and a landfill leachate MVR evaporation device containing the same. Background technique

[0002] There are different degrees of fouling problems in the heater of the evaporation concentration device, especially when the medium is sodium chloride, sodium sulfate, sodium hydroxide, magnesium chloride, magnesium sulfate and other inorganic salts, and landfill leachate treatment (high concentration organic wastewater) , Sewage treatment, food, sugar, papermaking, seawater desalination, oil field wastewater, diaphragm caustic soda, ionic membrane caustic soda and other evaporation concentration, crystallization heaters, due to the precipitation of dissolved substances in the feed liquid, the scaling problem is very prominent. Scaling is a common phenomenon in evaporative crystallization devices. Scaling of evaporative crystallization devices not only reduces the effective working volume of the e...

Examples

Embodiment 1

[0032] Embodiment 1, according to a certain proportion, the inert solid particles 4 of special specifications and sizes are first added to the bottom of the separator airtight tank 1 at one time through the inert solid particle inlet 14, and the high-concentration landfill leachate (or electroplating wastewater, heavy metal wastewater) at normal temperature ) after metering, enter the condensed water preheater 16 to increase the temperature of the feed liquid (preheated to the evaporation temperature) through the feed pump 15, enter the flotation device 7, pass through the discharge circulation pump 8, enter the feed pipe 6 and then enter the feed liquid Nozzle 2, the heated high-concentration landfill leachate is evenly distributed on the heating pipe 3 under the action of the feed liquid nozzle 2, and the steam compressor 11 is turned on at the same time, the heated high-concentration landfill leachate (or electroplating wastewater, heavy metal wastewater ) evaporate and vapo...

Embodiment 2

[0035] Embodiment 2, first according to a certain proportion, the inert solid particles 4 of special specifications and sizes are added to the bottom of the separator airtight tank 1 at one time through the inert solid particle inlet 14, and the high-concentration landfill leachate (or electroplating wastewater, heavy metal wastewater) at normal temperature ) after metering, enter the condensed water preheater 16 to increase the temperature of the feed liquid (preheated to the evaporation temperature) through the feed pump 15, enter the flotation device 7, pass through the discharge circulation pump 8, enter the feed pipe 6 and then enter the feed liquid Nozzle 2, the heated high-concentration landfill leachate is evenly distributed on the heating pipe 3 under the action of the feed liquid nozzle 2, and the steam compressor 11 is turned on at the same time, the heated high-concentration landfill leachate (or electroplating wastewater, heavy metal wastewater ) is evaporated and ...
