Description

Waste liquid inactivation system

Technical Field

Background

A large amount of biological wastewater can be generated in the fields of biological pharmacy, scientific research experiments and the like, the biological wastewater contains a large amount of bacteria and viruses, the biological wastewater can be treated again in wastewater treatment equipment after the bacteria and the viruses in the biological wastewater are subjected to inactivation process in an inactivation system, and the biological wastewater is qualified in treatment and can be discharged after reaching a discharge standard. The inactivation process means that the high-level structure of the virus protein in the live-toxin wastewater is destroyed by a physical method or a chemical method, and the protein has no physiological activity, thereby losing the capabilities of infection, pathogenesis and reproduction. High temperature has obvious lethal effect on microorganisms (bacteria, viruses and the like). The heat sterilization mainly uses high temperature to denature or coagulate the thallus, and the enzyme loses activity, so that the bacteria die. The process of bond breaking caused by heat absorption by chemical bonds in the DNA and RNA of the virus at high temperature is the core of high temperature inactivation of the virus. The chemical structures of bacterial proteins, nucleic acids and the like are connected by hydrogen bonds, but the hydrogen bonds are weak chemical bonds, when the bacteria are heated, the hydrogen bonds are destroyed, the structures of the proteins, the nucleic acids, the enzymes and the like are also destroyed, the biological activity is lost, and the bacteria die.

The collecting tank 100 in the waste liquid inactivation system can play a role in buffering waste liquid, and the waste liquid is not pressurized and heated, so the collecting tank 100 is usually designed to be a normal pressure container. The top of the holding vessel 100 of ordinary pressure container is provided with the blow-down valve and with the interlocked pressure sensor (not drawn in the figure) of blow-down valve, when pressure sensor detected the pressure in the holding vessel 100 too high, can open the blow-down valve automatically and carry out the pressure release to guarantee the safety of waste liquid inactivation system.

The waste fluid discharged from the chemical plant or pharmaceutical factory is buffered in the collection tank 100, and then transported in small quantities and batches to the inactivation tank 200 for inactivation through the first fluid transportation pipe 400.

As an example, in the embodiment, a waste liquid pipe 110 is provided on the collecting tank 100 and is communicated with the collecting tank 100, and a filter 111 for filtering waste liquid is further provided in the waste liquid pipe 110, so that waste liquid can be transported into the collecting tank 100 through the waste liquid pipe 110; moreover, the filter 111 can prevent solid particles in the waste liquid and medical supplies such as laboratory gloves from entering the collection tank 100, and thus, the collection tank 100 can be protected. The number of the filters 111 is not limited, and may be one, two or more. As an example, in the present embodiment, the number of the filters 111 on each waste liquid pipe 110 is two, one is a coarse filter and one is a fine filter.

The filter 111 for filtration needs to be replaced periodically, and the filter 111 needs to be replaced manually before replacement. However, since the filter 111 is often exposed to a pathogenic source, it needs to be sterilized before replacement. In this embodiment, a first steam pipe 120 communicating with the waste liquid pipe 110 is provided, and a first waste liquid valve 112 and a second waste liquid valve 113 are provided in the waste liquid pipe 110, respectively, and the filter 111 is located between the first waste liquid valve 112 and the second waste liquid valve 113.

The end of the gas delivery pipe 500 that communicates with the inactivation tank 200 is typically located at the top of the inactivation tank 200, and the end that communicates with the collection tank 100 is typically also located at the top of the collection tank 100 to prevent the waste fluid in the inactivation tank 200 from flowing back into the collection tank 100. In addition, to prevent the fluid in the collection tank 100 from flowing back into the inactivation tank 200, a check valve 510 is typically disposed on the gas delivery tube 500, with the check valve 510 being located in the gas delivery tube 500 near the inactivation tank 200.

After the pressure release is completed, the high-temperature liquid in the inactivation tank 200 is transported to the static mixer 300 through the second liquid transport pipe 410, the cooling is completed in the static mixer 300, and after the cooling is completed, the waste liquid in the static mixer 300 is discharged through the water outlet pipe 320; in order to ensure the transportation effect, two second transportation pumps 430 (one of which is active and the other one of which is standby) are further disposed on the second liquid transportation pipe 410 in this embodiment. Of course, in other embodiments, one or more than two second transport pumps 430 may be provided as long as the liquid in the inactivation tank 200 can be transported to the static mixer 300. In addition, in order to increase the cooling rate of the static mixer 300, a cooling pipe communicating with the static mixer 300 is usually disposed at the top of the static mixer 300, and a cooling liquid can be introduced into the static mixer 300 through the cooling pipe to rapidly complete cooling; the cooling pipes in this embodiment include a first cooling pipe 310 and a second cooling pipe 311, the first cooling pipe 310 is used for introducing tap Water, and the second cooling pipe 311 is used for introducing waste Purified Water (PW), which may also play a role in saving energy.

In the prior art, a tank body jacket is arranged on an inactivation tank 200 and is cooled by cooling water, or an external plate heat exchanger is used for circulating cooling, so that the equipment has high preparation cost and low cooling rate. This embodiment is through setting up a static mixer 300 again, directly mixes with the cooling water in static mixer 300, can reduce the preparation cost, can promote cooling rate again.
