Description

Technical Field

[0001] This utility model belongs to the field of fluorescent wastewater treatment, and in particular, it is a low-temperature evaporation device for fluorescent wastewater. Background Technology

[0002] Traditional evaporation devices typically introduce wastewater directly into the evaporation reactor for high-temperature heating and evaporation. However, when fluorescent wastewater contains insoluble salts, metal residues, or other impurities, these impurities are adsorbed into the reactor during high-temperature heating, making them difficult to remove. This usually requires shutdown for effective treatment, which disrupts the entire evaporation process and reduces its processing efficiency.

[0003] To prevent the formation of insoluble impurities in the evaporation vessel due to high temperatures, pressure reduction can be adopted to lower the boiling point of the solute, thereby reducing costs, protecting the original properties of the solute, and avoiding the formation of insoluble substances. However, the main component of fluorescent wastewater is organic fluorescent agent emulsion. As the concentration of fluorescent wastewater increases, the organic fluorescent agent emulsion will demulsify in the vessel, aggregate into clumps, and adsorb onto the reactor wall, causing similar problems again and affecting the continuous operation efficiency and processing capacity of the evaporation equipment.

DETAILED DESCRIPTION

[0024] In the following description, a large number of specific details are given to provide a more thorough understanding of the present application. However, it is apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other cases, some technical features known to the art are not described in order not to obscure the present application.

[0025] Referring to the drawings Figures 1 to 4 A low-temperature evaporation device for fluorescent wastewater, comprising: a pressure vessel 100, a scraper assembly and a stirring assembly.

[0026] The pressure vessel 100 is a closed device that can withstand a predetermined internal pressure inside. Of course, the pressure vessel 100 is designed with necessary inlet and outlet ports, a steam outlet 190, a pressure gauge, a safety valve, etc. to ensure safe operation and consistent process. Referring to the drawings Figure 4 The steam outlet 190 of the pressure vessel 100 is sealed and connected to the condenser 200, the liquid storage tank 300 and the vacuum pump 400 in sequence through a pipeline, forming a complete closed evaporation system.

[0027] Referring to the drawings Figure 2 The scraper assembly comprises a driving source mounted on the top plate 113 of the pressure vessel 100, a first gear 120 rotatably mounted below the top plate 113 and in transmission connection with the driving source, a mounting seat 130 mounted on the first gear 120 and coaxially rotatable with the first gear 120, and scraper pieces 140 arranged on both sides of the mounting seat 130 and extending to abut against the inner surface of the pressure vessel 100. The driving source comprises a motor 111 and a fourth gear 112 connected to the motor 111 and engaged with the first gear 120, respectively. The first gear 120 is rotated by the motor 111 mounted on the top plate 113 of the pressure vessel 100, the mounting seat 130 and the scraper pieces 140 are rotated, and the scraper pieces 140 can move along the inner wall of the container to effectively remove the deposits that may be formed.

[0028] Referring to the drawings Figure 3The stirring assembly is installed on the mounting seat 130 and is in transmission connection with the first gear 120. Specifically, the stirring assembly comprises a second gear 150 arranged in the mounting seat 130 and coaxially connected with the first gear 120, two third gears 160 installed in the mounting seat 130 and in engagement with the second gear 150, and two three-prong stirring paddles 170 rotatably installed on the mounting seat 130 and coaxially connected with the third gears 160 respectively. The stirring assembly is driven by the three-prong stirring paddles 170 installed on the same mounting seat 130 and the second gear 150 and the third gear 160, so that the three-prong stirring paddles 170 and the scraper assembly work synchronously, liquid mixing is promoted, and the organic fluorescent agent emulsion is prevented from breaking and gathering.

[0029] In further embodiments, the second gear 150 and the third gear 160 have a tooth number ratio of 5:1 to 25:1. The first gear 120 and the fourth gear 112 have a tooth number ratio of 5:1 to 25:1. In this way, a relatively high rotational speed of the three-prong stirring paddles 170 and a relatively low orbital speed along the central axis of the mounting seat 130 are achieved, so that the dynamic requirements in the low-temperature evaporation process are met.

[0030] In further embodiments, the driving source comprises two synchronous motors 111 and a fourth gear 112 connected with the motors 111 and in engagement with the first gear 120. The stirring assembly and the scraper assembly need to overcome a relatively large movement resistance, and the two motors 111 jointly act on the fourth gear 112, so that the total torque output of the transmission system is effectively improved, and the wastewater in various working conditions is more effectively treated, and the treatment efficiency is improved.

[0031] In further embodiments, the three-prong stirring paddles 170 are located at the middle part of the pressure container 100. The liquid in the entire container can be more effectively stirred, uniform solution mixing is ensured, and local temperature or concentration unevenness is prevented, especially for fluids such as fluorescent wastewater that need to be uniformly treated, the stirring at the middle position can minimize the dead angle and improve the treatment efficiency.

[0032] In further embodiments, the scraper member 140 comprises a base, a scraper, and an elastic member arranged between the base and the scraper. The presence of the elastic member enables the scraper to better adapt to the slight unevenness or deformation of the inner wall of the pressure container 100, so that even if the container slightly deforms in long-term use, the scraper can still maintain good adhesion, ensure scraping effect, and reduce residue.

[0033] In further embodiments, the pressure vessel 100 is provided with a temperature control assembly 180 on the inside or outside of the pressure vessel 100. The temperature control assembly 180 comprises an electric heating jacket provided on the side wall of the pressure vessel 100, a temperature sensor for detecting the temperature of the waste liquid in the pressure vessel 100, and a controller connected to the electric heating jacket and the temperature sensor. The temperature control assembly 180 is crucial for the efficiency of the evaporation process and the quality of the product, and is used to accurately regulate the temperature in the vessel to ensure that the evaporation is carried out at the set optimum temperature, preferably at a temperature of no more than 50°C, to avoid accelerated demulsification and deterioration of the organic fluorescent agent emulsion caused by overheating, and to reduce the out-calcification of inorganic salt.

[0034] It should be further noted that each of the technical features described in the foregoing embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present application will not further describe various possible combinations.
