Assembled high-speed railway air conditioner purifying and filtering device Technical Field The invention belongs to the technical field of air conditioner filtering devices, and particularly relates to an assembled high-speed rail air conditioner purifying and filtering device. Background The high-speed railway air conditioner purifying and filtering device is a core system for guaranteeing the air quality, the comfort level of passengers and the public health safety in a carriage, not only is the temperature and the humidity regulated, but also pollutants in the air are removed efficiently, a clean and healthy riding environment is provided for passengers and crews, the technical scheme of the high-speed railway air conditioner purifying and filtering device is required to meet four core requirements of air purifying efficiency, structural stability, light weight and maintenance convenience, and the requirements of the general technical condition of rail transit vehicle-mounted equipment (TB/T3021-2017) on the unit area weight and the dismounting time of the vehicle-mounted air conditioner filtering device are met. At present, a mainstream high-speed rail air conditioner filter device in the industry mainly comprises two technical schemes, namely a control cavity and a purifying cavity are divided by a partition board of the top wall in a carriage, a ventilator and an air outlet pipe are arranged in the control cavity, a semiconductor refrigerating sheet is arranged in the purifying cavity, air purification refrigeration after sudden power failure and interlocking function with a carriage air conditioning system are realized, and a metal outer frame filter device commonly adopted in the industry is mainly made of aluminum alloy or cold-rolled steel plates, the thickness of the outer frame is 2-3mm, the outer frame is spliced and molded through welding or bolts, a filter material and the outer frame are fixed through bonding, pressing and fixing by pressing strips or locking and fixing by bolts, and the installation mode is 4-8M 6-M8 bolts are fixed through or fastened and fixed through a buckle. The prior art and the main flow scheme have obvious defects, and the method is as follows: 1. The contradiction between the light weight and the rigidity is outstanding, namely, the metal outer frame needs to be made of thick plates to ensure the structural rigidity, so that the weight per unit area is generally 4.2-5.8kg/m < 2 >, which exceeds 20% -66% of the TB/T3021-2017 standard requirement, the energy consumption of high-speed rail operation is increased, and a few thin-wall or plastic outer frames are easy to deform in the light weight scheme of the high-speed rail vibration environment, so that the gap between the filter material and the outer frames is increased, the unfiltered air leakage rate is more than or equal to 5%, and the purification effect is seriously influenced. 2. The disassembly and maintenance efficiency is low, the quick-wear parts are damaged, the bolts are required to be disassembled one by one in a bolt fixing mode, the single disassembly and assembly time is 20-40 minutes, the time is far beyond the industry standard, the inner space of the high-speed rail air conditioning unit is narrow, the spanner is easy to slip, according to the statistics of industry maintenance data, the scratch of the inner wall of the air conditioning unit and the deformation accidents of the heat exchanger fins caused by the slipping of tools account for 32% of the total number of maintenance accidents each year, the problems of easy loosening due to vibration and aging and fracture due to long-term use exist in the buckle type lock catch structure, and the maintenance cost is high. 3. The filter material replacement cost is high, the sealing reliability is poor, the filter material and the outer frame are of an integrated fixing structure, the replacement is carried out by an integral dismounting device or all pressing strips/bolts are dismounted, the operation is complex, 2-3 maintenance personnel are required to cooperate, the pollution rate of the filter material in the replacement process is about 15%, the filter materials with different functions cannot be switched in a modularized mode, the installation fitting degree depends on manual operation, and unfiltered air leakage is easily caused by loose sealing. 4. The long-term use stability is insufficient, the metal outer frame is easy to corrode due to the change of the humidity of a carriage, the creep resistance of the plastic outer frame is poor, the plastic outer frame is easy to warp and deform after long-term use, the annual average attenuation rate of the filtering efficiency is more than or equal to 8%, and the service life of the device is influenced. Therefore, the invention provides an assembled high-speed rail air conditioner purifying and filtering device. Disclosure of Invention In order to make up the deficiency of the prior art, the inve
