Problems solved by technology

Especially in the hazardous waste industry, the acid-base concentration of the collected wastewater varies, and some even reach more than 50%. If these high-concentration acid-base waste liquids are treated separately or discarded, there are problems such as high cost and relatively large pollution. The acid-base neutralization water treatment method is the most common and effective method to deal with this kind of wastewater. However, the high-concentration acid-base is highly corrosive, and the acid-base neutralization reaction will generate a lot of heat. These two characteristics make this type of wastewater Processing requires a dedicated reactor
[0003] And the reactor that existing waste water acid-base neutralization is used has following defect: 1) because acid-base neutralization can produce a large amount of heat, and existing reactor does not have self-contained cooling system to cool down reaction medium, neutralization reaction The heat will cause damage to the reaction equipment and instruments, and also increase the risk of operation; 2) because the neutralization reaction sometimes produces sediment, and the existing reactor does not have the function of removing slag, it is easy to cause blockage inside the reactor, Affect its normal use; 3) During the neutralization reaction inside the reactor, in order to increase the reaction rate, the neutralized liquid will be stirred, and during the stirring process, the acid and alkali liquid will splash to the joint between the tank cover and the tank body 4) It is not possible to add additives quantitatively in batches, which will reduce the effect of sewage treatment

Embodiment Construction

[0038] Example: such as figure 1 , 2 As shown, a cooling reactor for acid-base neutralization of waste water with the function of removing slag, including a tank body with a tank cover 10 connected to the upper end through a flange, a discharge port 11 at the bottom end, and a jacket 12 on the outer wall 1. Stirring and slag removing element 2 vertically installed in the tank body 1, cooling water tank for cooling the tank body 1 3, mist cooling and collecting element 4 for collecting acid and alkali mist in the tank body 1, volume control adding element 5 . An intelligent control element 6 for controlling the normal operation of each electrical component and a power supply for providing electrical energy to each electrical component;

[0039] A cooling cavity 120 is formed between the jacket 12 and the outer wall of the tank body 1, and the side wall of the jacket 12 is provided with a cooling water inlet 121 and a cooling water outlet 122;

Abstract

The invention provides a cooling reactor having a slag salvaging function and used for wastewater acid-base neutralization, and application thereof. The cooling reactor comprises a tank body, a stirring and slag salvaging element, a cooling water tank, a mist cooling and collecting element, a quantity control adding element, an intelligent control element and a power supply. According to the invention, the reactor with the cooling function can be used for cooling a reaction medium, ensuring the safety of operation and regions, and quantitatively adding neutralizing agents in batches, so that the sufficient reaction of the neutralizing agents with waste acid and waste alkali can be ensured while the quantitative addition is met, and the treatment effect is improved; by arranging two annularseal strip plates which can be buckled with each other, the situation that acid and alkali in the tank body are splashed during stirring to corrode the sealing ring between the tank cover and the tank body so as to cause leakage to cause production accidents is avoided; and when the temperature in the tank body rises, the cooling channels also exist in the annular seal strip plates to cool the annular seal strip plates, so that the aging of the sealing ring due to local temperature rise can be avoided, and the service life of the device is shortened.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a cooling reactor for acid-base neutralization of wastewater with the function of removing slag and its application. Background technique [0002] Industrial wastewater includes production wastewater, production sewage and cooling water, etc. It refers to wastewater and waste liquid generated in the process of industrial production, which contains industrial production materials, intermediate products, by-products and pollutants generated in the production process lost with water. Because industrial wastewater often contains a variety of toxic substances, these substances have serious harm to the environment and human health. Especially in the hazardous waste industry, the acid-base concentration of the collected wastewater varies, and some even reach more than 50%. If these high-concentration acid-base waste liquids are treated separately or discarded, t...
