Description

Technical Field

[0001] This utility model mainly relates to the technical field of biological waste liquid inactivation treatment, specifically a biological waste liquid inactivation tank. Background Technology

[0002] For pharmaceutical factories and research institutions, the biological wastewater inactivation treatment system mainly adopts the wet heat sterilization method. During the inactivation process, steam is needed to heat and inactivate the wastewater. The temperature of the wastewater after inactivation is relatively high, and the heating rate is slow when using the ordinary bottom heating method.

[0003] Biological waste inactivation tanks are an important component of biological waste inactivation treatment systems. Commercially available biological waste inactivation tanks primarily use bottom-inlet steam, which not only results in high equipment noise but also slow heating. Furthermore, the lack of bottom baffles makes them prone to eddies during drainage, leading to poor drainage and affecting the operation of subsequent circulating water pumps. Most also lack bottom valves, instead connecting to other valves via straight pipes, requiring additional sterilization methods and increasing control requirements. Utility Model Content

[0004] To address the shortcomings of current technology, this utility model, based on existing technology and practical application, provides a novel biological waste liquid inactivation tank. Primarily serving as a key component of a biological waste liquid inactivation treatment system, it features a compact structure, reliable operation, and effectively improves the inactivation heating rate, thus saving energy.

[0005] The technical solution of this utility model is as follows: A biological waste liquid inactivation tank includes an inactivation tank body and a steam pipeline. The steam pipeline is disposed inside the inactivation tank body and has at least two steam outlets. The at least two steam outlets are arranged at 180° around the circumference of the inactivation tank body, and the steam outlets spray downwards at an angle inside the inactivation tank body. Each steam outlet is equipped with a steam injector.

[0006] Furthermore, the steam pipeline includes a steam outlet pipeline and a steam inlet pipeline. The steam outlet pipeline has steam outlets at both ends. One end of the steam inlet pipeline is connected to the middle of the steam outlet pipeline, and the other end is connected to the flange on the outside of the inactivation tank.

[0007] Furthermore, a bottom valve is provided at the bottom of the inactivation tank, and a baffle is provided at the bottom of the inactivation tank corresponding to the position of the bottom valve.

[0008] Furthermore, the baffle plate comprises two stainless steel plates arranged in a cross shape, which are welded to the bottom of the inactivation tank.

[0009] Furthermore, the inactivation tank is also equipped with a temperature sensor interface, a sampling port, and an online verification port.

[0010] Furthermore, a level gauge interface is provided at the bottom of the inactivation tank.

[0011] The beneficial effects of this utility model are: 1. In this utility model, the steam jet is installed at an angle, which can simultaneously play a vortex stirring role during the steam jet process, resulting in low noise and fast heating rate inside the inactivation tank.

[0012] 2. The bottom valve of the tank in this utility model can effectively shorten the pipeline and reduce the risk of incomplete disinfection of toxic waste liquid. Combined with the design of the baffle plate, it is easy to reduce the influence of eddies when draining, and can discharge waste liquid more effectively.

[0013] 3. This utility model is equipped with temperature detection, liquid level detection, and pressure detection ports, which can monitor the temperature, pressure, and liquid level inside the inactivation tank in real time, ensuring the safe operation of the equipment.

[0020] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0021] This embodiment provides a biological waste liquid inactivation tank, which is mainly used as a key component of a biological waste liquid inactivation treatment system. Its structure is referenced. Figures 1-5 As shown.

[0022] The biological waste inactivation tank of this embodiment mainly includes an inactivation tank body 1 and a steam pipeline 2. The steam pipeline 2 mainly includes a steam outlet pipeline 22 and a steam inlet pipeline 21. The steam inlet pipeline 21 is connected to the steam inlet of the inactivation tank body 1 by welding. The middle of the steam outlet pipeline 22 is connected to the steam inlet pipeline 21. A steam ejector 3 is installed at each end of the steam outlet pipeline 22. The two steam ejectors 3 are arranged at 180° along the circumferential direction of the inactivation tank body 1, and the outlets of the steam ejectors 3 face downwards. Thus, the two downward-facing steam ejectors 3 simultaneously create a vortex stirring effect during the steam ejection process, ensuring a balanced temperature rise and efficient temperature rise within the inactivation tank body 1.

[0023] The baffle 4 is located at the bottom center of the inactivation tank body 1. The baffle 4 consists of two cross-shaped stainless steel plates welded together perpendicularly. It is connected to the bottom of the inactivation tank body 1 by welding to reduce eddy currents during drainage and prevent air from entering the subsequent circulating water pump and causing cavitation. The bottom valve 5 is directly connected to the bottom of the inactivation tank body 1 by welding, reducing the distance of the short pipe and avoiding the risk of cold spots.

[0024] Temperature sensor interface 6 is welded to the inactivation tank body 1 using an NA flange, effectively reducing cold spots and ensuring sterilization reliability. The temperature sensor connection is convenient and can effectively detect the inactivation temperature. Sampling port 7 is welded to the side wall of the inactivation tank body 1 using an NA flange, effectively reducing cold spots and ensuring sterilization reliability. Online verification port 8 is welded to the inactivation tank body 1 using an NA flange, with a blind end extending into the inactivation tank to contact the waste liquid. Heat inside the inactivation tank can be transferred to online verification through the tank wall. During verification, ampoules containing spores are fixed to the spore detector and wrapped with a saturated wet towel. The entire test pack is inserted into online verification port 8. The heat inside the tank causes the water on the wet towel to evaporate and generate heat. This humid environment is similar to the working conditions inside the inactivation tank. The spores are completely isolated inside the ampoule, thus simulating the environment inside the inactivation tank. The test pack can be removed at any time during the cycle. If the spores are killed, it proves that the provided treatment parameters are correct. The level gauge connection port 9 is welded to the inactivation tank body 1 using an NA flange. This connection at the bottom of the inactivation tank body 1 effectively reduces cold spots, ensuring sterilization reliability and data accuracy. The inactivation tank body 1 is externally wrapped with insulation material and stainless steel plates to ensure the equipment's surface temperature is ≤45℃ and maintains its aesthetic appeal.
