Train compartment air purification system

Abstract

The invention discloses a train compartment air purification system, and relates to air purification equipment. According to the technical scheme, the system consists of an air purification unit and an air quality detection display unit; an air inlet of a central air conditioner in the train compartment is provided with a purification device, the air in the compartment and the fresh air in the train are mixed in an air mixing box and then continuously circulate to enter the purification device; after being purified, the air is sent to each air outlet through a pipeline of the central air conditioner, so that the purpose of purification is achieved; the purification device is provided with a purification material containing polydopamine and silver ions, and the polydopamine is used for removing TVOC, the silver ions are used for killing and inhibiting germs; the air quality detection module is used for detecting the air quality in the compartment in real time, an air quality display screen displays main indexes of the air pollutants in the compartment in real time and transmits the main indexes to a main train department in real time. The system has the beneficial effects that the air quality of train compartments such as high-speed railway, subways, urban rails and the like can be effectively improved.

Description

technical field [0001] An air purification system for train carriages relates to air purification equipment, in particular to an air purification equipment installed and used on train carriages. Background technique [0002] Now, the scale of China's high-speed rail has firmly ranked first in the world. It has become the first choice for people to travel because of its speed and convenience. However, the air quality in the carriages is often not up to standard, which brings harm to the health of passengers; the main cause of air pollution in the carriages It is: (1) TVOC and other harmful substances continuously released from interior decoration materials, hydraulic pipes, wires and cables, etc.; (3) The air pollution outside the car is serious. During the ventilation process, TVOC volatile organic compounds, sulfur dioxide, nitrogen oxides, PM2.5 smog particles, etc. will inevitably flow into the car. According to the test, the pollution in the car is mainly caused by TVOC...
