Description

Technical Field

[0001] The utility model relates to the technical field of biopharmaceutical equipment, and more specifically to an exhaust gas sterilizer. Background Art

[0002] With the rapid development of science and technology and economy, the national living standards have been greatly improved, the pursuit of health quality has been continuously increased, and the scale of biopharmaceutical industry has expanded rapidly. However, in the biopharmaceutical industry, due to the large amount of fermentation air used in the biopharmaceutical process, generally 1:0.5~1.2 (VVM), whether it is the experimental drug research process or the actual drug production process, a large amount of polluting harmful gases will be generated. The pollutant factors mainly include acidic gases, alkaline gases, organic waste gases and other pollutants.

[0003] When a large amount of untreated exhaust gas is discharged into the atmosphere, some fermentation metabolites are also carried out with the exhaust gas, and even a special unpleasant odor is produced. If these pollutants are not purified and discharged, they will cause harm to the environment and human health. In order to reduce air pollution, purify the air and meet emission standards, this plan proposes an exhaust sterilizer that can purify waste gas. Utility Model Content

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "set / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example

[0025] See also Figure 1-3 A tail gas sterilizer comprises an air filter box 1, an air inlet pipe 2 is installed at the left end of the air filter box 1, a cover 3 is threadedly connected to the right end of the air filter box 1, an air outlet pipe 4 is installed at the right end of the cover 3, and a purification component is arranged inside the air filter box 1; the purification component comprises a filter screen 71, a ventilation pipe 72, a filter plate 1 73 and a filter plate 2 74 which are arranged in sequence from left to right, and a connecting plate 75 is installed correspondingly between the spacings of the filter screen 71, the ventilation pipe 72, the filter plate 1 73 and the filter plate 2 74.

[0026] During use, in order to avoid the harmful gases and waste gases generated in the existing biopharmaceutical industry being directly discharged into the air and causing harm, in this embodiment, the harmful gases entering the air filter box 1 are purified and adsorbed layer by layer under the purification component, and the pollutants in the tail gas are filtered out to reduce the pollution of the tail gas to the environment. At the same time, the purification component can be taken out by rotating the cover 3 for replacement, cleaning and maintenance, so that the tail gas sterilizer has a simple structure and convenient operation when in use, which prevents harmful objects in the tail gas from polluting the environment while facilitating maintenance and cleaning.

[0027] When in use, the operator first rotates to open the cover 3, inserts the purification component into the air filter box 1, and then connects the cover 3 to the air filter box 1, and then connects the air intake pipe 2 to the required emission pipe or equipment. Thereafter, the purification component filters and adsorbs the waste gas and harmful gas, and filters out the pollutants in the exhaust gas, thereby reducing the pollution of the exhaust gas to the environment. When it is necessary to clean the pollutants adsorbed inside the purification component later, the operator only needs to rotate the cover 3 out, take out the purification component and clean it.

[0028] See also Figure 1-3 A threaded column 5 is fixedly connected to the left end of the cover 3 , and a threaded groove 6 is opened on the right side inside the air filter box 1 , and the threaded column 5 is installed in the threaded groove 6 .

[0029] Specifically, a plurality of staggered bronchial tubes 721 are installed inside the ventilation pipe 72 .

[0030] Specifically: a heater is installed on the inner wall of the connecting plate 75 .

[0031] Specifically: the filter plate 1 73 is an activated carbon filter plate, and the filter plate 2 74 is a PP cotton filter element plate.

[0032] During use of the present solution, after the exhaust gas and harmful gas enter the air filter box 1 through the air inlet pipe 2, the larger pollutants are first blocked by the filter screen 71, and then the gas continuously enters the ventilation duct 72. Due to the multiple staggered bronchial tubes 721 arranged inside the ventilation duct 72, the time for the gas to pass through the ventilation duct 72 is prolonged. In addition, since the space is narrow, the heater on the inner wall of the connecting plate 75 continuously releases heat to the outside, and the gas is continuously sterilized by high temperature when passing through the bronchial tube 721, thereby being further purified. Subsequently, the purified gas is filtered and adsorbed through the filter plate 1 73 set on the activated carbon filter plate and the filter plate 2 74 set on the PP cotton filter element plate, and the pollutants in the exhaust gas are filtered out. Finally, the exhaust gas is discharged from the exhaust pipe 4, which greatly reduces the pollution of the exhaust gas to the environment.

[0033] See also Figure 1-2 A connecting rod 76 is fixedly connected between the ventilation duct 72 and the inner wall of the filter plate 73, and a fan blade 77 is rotatably connected to the outer end of the connecting rod 76.

[0034] During use of this solution, when the exhaust gas is being purified, after the airflow flows out from the bronchial duct 721, the fan blades 77 are caused to rotate on the surface of the connecting rod 76 under the guidance of the airflow, so that the gas sterilized by high temperature from the bronchial duct 721 can contact the filter plate 1 73 and the filter plate 2 74 over a larger area after being stirred by the fan blades 77, thereby further improving the exhaust gas purification efficiency.

[0035] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
