Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, and in particular to a spray drying device for high-salt wastewater. Background Technology

[0002] High-salt wastewater spray drying technology is a highly efficient process for treating high-salt, high-concentration organic wastewater. Its core purpose is to separate salt from water through rapid evaporation, thereby reducing the volume of wastewater. In the prior art, a utility model patent with patent application number 202222866250.6 discloses a novel anti-clogging and anti-sticking spray dryer, which mainly consists of a drying tower, a delivery pump, and nozzles. During use, the pump delivers wastewater to the nozzles, which then spray the wastewater into the drying tower to form a water mist. Simultaneously, a heating device inside the drying tower is activated to heat the water mist, causing the water in the mist to evaporate. The evaporated salt forms solid particles that fall to the bottom of the drying tower. However, this method has the following problem: when the water mist dries inside the drying tower, some of the dried salt adheres to the inner wall of the drying tower. When the salt is discharged from the drying tower, manual cleaning of the salt adhering to the inner wall is required, which is inconvenient. Therefore, a spray drying device that can assist workers in cleaning the salt on the inner wall of the drying tower is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a spray drying device for high-salt wastewater that can assist workers in cleaning the salt adhering to the inner side wall of the drying cylinder, reducing labor intensity, and is easy to use and highly practical.

[0004] This utility model discloses a spray drying device for high-salinity wastewater, comprising a base plate, a support, a drying cylinder, and a sealing cover. The drying cylinder is fixedly mounted on the upper part of the base plate via the support. A chamber is provided inside the drying cylinder, and an opening communicating with the chamber is provided at the lower part of the drying cylinder. The sealing cover is bolted to the outside of the opening. Multiple heating plates are mounted on the drying cylinder, all embedded in the inner wall of the drying cylinder. Multiple heating lamps are mounted at the upper end of the drying cylinder chamber. The device also includes a preheating mechanism, a spraying mechanism, and a cleaning mechanism. The cleaning mechanism is mounted on the drying cylinder and the base plate and is used to clean the inner wall of the drying cylinder. The output end of the spraying mechanism communicates with the upper part of the drying cylinder chamber and has a spraying function. The preheating mechanism is connected to the input end of the spraying mechanism and has a preheating function. Its functions include: when drying high-salt wastewater, the wastewater is first heated to a certain temperature in the preheating mechanism, and then sprayed into the drying cylinder chamber through the spray mechanism to form a water mist. At the same time, multiple electric heating lamps and multiple electric heating plates in the drying cylinder chamber are turned on to heat the water mist, causing the water in the mist to evaporate and the salt in the mist to solidify and fall to the lower end of the drying cylinder chamber. When it is necessary to clean the solid salt in the drying cylinder chamber, the cleaning mechanism is turned on to clean the salt adhering to the inner wall of the drying cylinder, so that the salt adhering to the inner wall of the drying cylinder is cleaned to the lower end of the drying cylinder chamber. It can assist workers in cleaning the salt adhering to the inner wall of the drying cylinder chamber, reduce labor intensity, is easy to use, and has high practicality.

The atomizing nozzle is installed on the upper part of the drying cylinder, and the output end of the atomizing nozzle is located in the chamber of the drying cylinder. When drying high-salt wastewater, the delivery pump is turned on, so that the wastewater heated in the preheating mechanism enters the atomizing nozzle sequentially through the input pipe, the delivery pump, and the output pipe. Then, the high-salt wastewater is sprayed into the chamber of the drying cylinder through the atomizing nozzle to form a water mist, which facilitates the treatment of high-salt wastewater.

[0006] Preferably, the cleaning mechanism includes a motor, a rotating shaft, a fixed frame, a connecting rod, and a scraper.

[0008] Preferably, it also includes a filter plate, which is fixedly installed in the upper part of the heating box cavity. With the above configuration, when wastewater is added into the heating box cavity through the inlet funnel, the wastewater first passes through the filter plate. The filter plate filters out large solid impurities in the wastewater in advance, avoiding blockage of the atomizing nozzle by solid impurities in the wastewater. It is convenient to use and has high reliability.

[0009] Preferably, it also includes a booster pump, which is fixedly installed on the heating box; when heating the wastewater in the heating box, the booster pump is turned on to increase the pressure in the heating box, raise the boiling point of the wastewater in the heating box, so that the wastewater in the heating box can be heated to a higher temperature.
