Description

Technical Field

[0001] This utility model relates to the field of diagnostic reagent technology, and in particular to a disinfection device for simulating wastewater from biochemical experimental samples. Background Technology

[0002] The production of reagent kits (especially biological diagnostic kits, such as nucleic acid detection kits and immunodiagnostic kits) involves various biochemical experiments to ensure the purity of raw materials, reaction efficiency, and product stability. This process also generates specific types of biochemical experimental wastewater. For example, sample simulation wastewater contains residual liquids simulating clinical samples (such as proteins, lipids, and electrolytes in simulated serum), and may contain small amounts of preservatives (such as sodium azide, which is highly toxic) or anticoagulants (such as EDTA). Currently, for this type of wastewater, a reagent is first added to precipitate sodium azide, followed by the addition of a flocculant to precipitate proteins and lipids. After filtration to remove the precipitates, the wastewater undergoes fermentation to further decompose proteins and lipids. The filtered liquid is then treated by disinfection equipment before being discharged. Existing technology often uses chlorine dioxide disinfection equipment, but the mixing of chlorine dioxide and wastewater is uneven, affecting disinfection efficiency. Therefore, to address the above problems, it is necessary to develop a disinfection device for biochemical experimental sample simulation wastewater. Utility Model Content

[0012] After adopting the above technical solution, the beneficial effects of this utility model are:

[0013] The disinfection device used to simulate wastewater in biochemical experiments includes a sodium chlorite storage tank and a hydrochloric acid storage tank. These tanks are connected to a first reaction vessel via sodium chlorite and hydrochloric acid delivery pipes, respectively. The disinfectant outlet and wastewater delivery pipe of the first reaction vessel are connected to a static mixer, the outlet of which is connected to a second reaction vessel, and the outlet of the second reaction vessel is connected to a wastewater discharge pipe. In actual production, sodium chlorite from the sodium chlorite tank and hydrochloric acid from the hydrochloric acid tank enter the first reaction vessel via the sodium chlorite and hydrochloric acid delivery pipes, respectively. After sufficient reaction, chlorine dioxide and wastewater are prepared and then enter the static mixer. After preliminary mixing, they enter the second reaction vessel, where chlorine dioxide comes into full contact with the wastewater, achieving disinfection. The disinfected wastewater is then discharged through the wastewater discharge pipe. This disinfection device is rationally designed and significantly improves the disinfection efficiency of wastewater.

[0014] Precision metering pumps are installed on both the sodium chlorite and hydrochloric acid delivery pipelines. These pumps allow for precise control of the addition of sodium chlorite and hydrochloric acid to the first reaction vessel according to a set ratio.

The vessel body is equipped with a jacket, and inside the vessel body are a rotating shaft, a first distributor connected to the sodium chlorite inlet pipe, and a second distributor connected to the hydrochloric acid inlet pipe. Multiple stirring components are mounted on the rotating shaft. In actual production, sodium chlorite and hydrochloric acid are introduced into the vessel body separately via precision metering pumps. Sodium chlorite is evenly dispersed in the first distributor, and hydrochloric acid is evenly dispersed in the second distributor. The heat transfer medium in the jacket provides the necessary temperature for the reaction. With the action of multiple stirring components, the two react in full contact, greatly improving the conversion rate of chlorine dioxide.

[0016] Both the first and second liquid distributors include a hollow disc body with multiple distribution tubes connected to it, and each tube has multiple distribution holes. Sodium chlorite and hydrochloric acid enter the interiors of the first and second distributors respectively, and then flow into the interconnected distribution tubes. After being evenly dispersed through the distribution holes, they undergo a contact reaction. The first and second distributors are rationally designed to achieve sufficient dispersion of sodium chlorite and hydrochloric acid, which further facilitates their full contact reaction and promotes the synthesis of chlorine dioxide.

[0017] The system comprises multiple stirring components, including a first stirring component, a second stirring component, and a third stirring component. Both the first and third stirring components include a fixed base with multiple trapezoidal stirring plates featuring a perforated structure. The second stirring component includes a cylindrical stirring tank with a perforated structure and multiple stirring rods. A rotating shaft drives the fixed base, the multiple trapezoidal stirring plates, the stirring tank, and the multiple stirring rods to rotate, achieving thorough mixing of the liquid inside the vessel and promoting full contact and reaction between the two components.

[0018] The second reaction vessel includes a vessel body with an inlet and an outlet at the top and bottom, respectively. Inside the vessel body is a rotating shaft, one end of which is connected to a motor. A trapezoidal stirring frame is mounted on the shaft, and multiple perforated stirring plates are mounted on the frame. Wastewater containing chlorine dioxide enters the vessel body. Once the motor starts, it drives the rotating shaft, the trapezoidal stirring frame, and the perforated stirring plates to rotate, thus mixing the wastewater and chlorine dioxide and ensuring thorough contact between them, thereby disinfecting the wastewater.

[0024] In actual production, under the action of a precision metering pump, sodium chlorite in the sodium chlorite storage tank and hydrochloric acid in the hydrochloric acid storage tank enter the interior of the first reactor through the sodium chlorite delivery pipeline and the hydrochloric acid delivery pipeline, respectively. Sodium chlorite is evenly dispersed after entering the first distributor, and hydrochloric acid is evenly dispersed after entering the second distributor.

After the motor is started, it drives the rotating shaft, trapezoidal stirring frame and multiple hollow structure stirring plates to rotate, realizing the stirring and mixing of wastewater and chlorine dioxide, promoting full contact between the two, and thus achieving disinfection of wastewater.

Sodium chlorite and hydrochloric acid enter the interiors of the first and second liquid distributors respectively, and then enter the multiple connected liquid distribution pipes. After being evenly dispersed through the liquid distribution holes, they undergo a contact reaction. The first and second liquid distributors are rationally designed to achieve sufficient dispersion of sodium chlorite and hydrochloric acid, which further facilitates their full contact reaction and promotes the synthesis of chlorine dioxide.
