Description

Technical Field

[0001] The present invention relates to the field of wastewater treatment, and in particular to a boiler wastewater treatment device. Background Art

[0002] Boiler wastewater refers to the various types of sewage or wastewater generated during boiler operation, maintenance, and related processes. Its composition and properties vary significantly depending on boiler type, fuel type, operating parameters, and water treatment process. Direct discharge of this wastewater without proper treatment can cause environmental pollution, necessitating targeted treatment and management.

[0003] Since various chemical molecules remain in boiler wastewater, its treatment cannot be achieved simply through physical steps such as filtration. Instead, it requires the use of reagents such as precipitants and neutralizers to neutralize the chemical molecules inside. This not only forces the precious metals to precipitate, but also neutralizes its pH value, reducing its harm to the environment.

[0004] In the existing technology, when performing chemical treatment, sewage is mostly directly guided into the interior of the reaction tank, and then reagents are added to achieve chemical treatment. However, in actual operation, the total amount of wastewater treated each time cannot remain exactly the same. In this way, the total amount of reagents required each time cannot be determined. If too much reagent is added, it will lead to waste, and if too little reagent is added, it will lead to incomplete treatment. Therefore, a boiler wastewater treatment device is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems raised in the above-mentioned background technology, and then propose a boiler wastewater treatment device.

In this way, when dosing, it is only necessary to fill the interior of the liquid storage box. The overall device is more convenient in controlling the dosing, and the amount of medicine can be adjusted according to the amount of sewage, which can fully treat the wastewater and save costs.

The left end of the flow pipe 42 connected to the cell body 1 is installed on the inner wall of the drainage pipe 51. The group of flow pipes 42 can be used to guide the medicine inside the liquid storage box 41 into the inner wall of the drainage pipe 51.

The left end of the fusion tube 54 is fixedly connected to the right end of the hole plate 57. When the medicine is administered, the gas-liquid mixture discharged from the left end of the fusion tube 54 will pass through the hole plate 57, so that the gas-liquid mixture can form bubbles. Subsequently, this part of the gas-liquid mixture will pass through the hole plate 57 again from left to right, so that the bubbles are further refined. The inner wall of the fusion tube 54 is provided with a guide plate 55 for guiding the flow of the gas-liquid mixture. The guide plate 55 is set in a spiral shape.
