Description

Technical Field

[0001] The utility model relates to the field of mechanical devices, in particular to a residual ozone exhaust system. Background Art

[0002] In the standard specifications for the production of pharmaceutical preparations, there are strict requirements for the cleanliness of the production environment, especially for dosage forms such as injections and ophthalmic preparations, which have extremely strict requirements for the aseptic conditions of the production area. In order to meet the qualified production environment standards, the industry currently uses ozone to treat the production workshop. However, ozone is a substance that can cause damage to human health. Long-term or high-concentration exposure to ozone may cause respiratory irritation, sore throat, chest tightness, coughing and other problems. In severe cases, it may cause bronchitis and emphysema. Excessive concentrations of ozone may cause neurotoxic reactions, leading to symptoms such as headaches and dizziness, and in severe cases, it may also affect memory. Generally speaking, after the production environment is sterilized, the residual ozone should be removed as much as possible to ensure the safety of production personnel. Before the ozone is completely discharged, if the staff mistakenly enters the sterilization area where ozone still remains, it may cause damage to the health and safety of the personnel. Utility Model Content

[0003] Therefore, in order to prevent the staff from mistakenly entering the sterilization area where ozone still remains, we have designed a residual ozone exhaust system, the components of which are controlled by a unified linkage, and the door is locked from the outside before the ozone is completely exhausted, so that people can only exit but not enter, preventing people from entering. It is characterized in that the system consists of an air-conditioning unit, an ozone unit, a negative pressure air outlet, a normal pressure air intake valve, a high pressure air intake valve, a workshop, a first valve, a second valve, a third valve, a fourth valve, an ozone concentration detector, an ozone pipe, a first circulation pipe, and a second circulation pipe. The air inlet end of the air-conditioning unit is connected to the workshop through the first circulation pipe, and the first valve is arranged on the first circulation pipe; the air outlet end of the air-conditioning unit is connected to the workshop through the second circulation pipe; the air inlet end of the air-conditioning unit is connected to the workshop through the ozone pipe, and the second valve, the third valve, and the fourth valve The door is arranged on the ozone pipe, the first branch of the ozone pipe is located between the second valve and the third valve on the ozone pipe, and the ozone unit is connected to the ozone pipe through the first branch of the ozone pipe; the second branch of the ozone pipe is located between the third valve and the fourth valve on the ozone pipe, and the negative pressure air outlet is connected to the ozone pipe through the second branch of the ozone pipe; the atmospheric pressure air intake valve and the high pressure air intake valve are connected to the ozone unit through pipelines respectively; the ozone concentration detector is arranged in the workshop, and is connected and controlled with the first valve, the second valve, the third valve, the fourth valve and the workshop door through a data line.

[0004] Furthermore, the ozone concentration detection safety threshold of the ozone concentration detector is 2 ppm.

[0005] Beneficial effects: Efficiently discharge residual ozone in the sterilization area, lock the area before the residual ozone concentration reaches the standard, prevent people from entering, and improve production efficiency and safety. BRIEF DESCRIPTION OF THE DRAWINGS
