Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photocatalytic poison degradation and filtration, in particular to a photocatalytic poison degradation and filtration reaction device. Background Art
[0002] The ventilation and gas filtration systems of national defense fortifications, civil air defense command fortifications, various professional support unit shelter fortifications and mobile combat vehicles have the following problems in use:
[0003] 1. Low anti-toxicity ability against difficult-to-absorb toxic agents
[0004] The various types of gas filters currently used in fortifications mainly use activated carbon adsorption, which has a short protection time against difficult-to-adsorb toxic agents such as cyanogen chloride.
[0005] 2. The protective performance is greatly affected by humidity
[0006] Gas filters that have become damp due to improper use or storage and have been stored for more than a year should be replaced. Even if the time since they became damp is not long, their effectiveness in protecting against poorly adsorbed agents such as cyanogen chloride will be significantly reduced.
[0007] 3. It is difficult to detect the remaining antivirus time
[0008] Due to the unstable protective ability of the gas filter and the different use conditions, moisture conditions and operation history, the remaining anti-gas time of the gas filter must be accurately and quickly determined. However, the current methods for detecting the remaining anti-gas time are insufficient. The carbon layer needle puncture method is semi-quantitative and inaccurate; the strong adsorbent pulse attenuation method is destructive to the equipment.
[0009] 4. Inconvenient to transport and replace
[0010] After the gas filter is protected from poison, the air inlet, diffuser and activated carbon are all adsorbed with poison. Therefore, when replacing equipment, the gas filter chamber will be desorbed and contaminated. The operator needs to wear protective equipment, and the used equipment must be sealed and stored. In addition, the gas filter is large in size and heavy in weight, making it inconvenient to carry and replace.
[0011] 5. The alarm system is defective
[0012] There is a loophole in only issuing an alarm for phosphorus-containing toxic agents.
[0013] In view of the above reasons, it is necessary to develop a new type of reactor that can degrade various toxic agents, has little impact on the environment, can be reused, and is easy to replace. Utility Model Content
