Background

Urban rail transit stations are usually located underground, free ventilation and air exchange of the stations are difficult to carry out by utilizing natural wind, and energy consumption of an environment control system is huge. The traditional shielding door system arranged at the station can effectively reduce the influence of noise and piston wind on platform passengers, and reduce the operation energy consumption of the central control system in air conditioning seasons; but the shield door encloses the subway station into semi-closed space simultaneously, can't utilize free piston wind to carry out ventilation to the platform, can only utilize mechanical ventilation to reach and eliminate waste heat and take a breath in the transition season, and the ventilation energy consumption is higher. The safety door system can effectively utilize piston wind to ventilate and ventilate a station platform in a transition season, but pollutants such as dust, metal particles and the like in a tunnel enter the station platform along with the piston wind, so that the health of waiting passengers and workers is seriously harmed; and the train braking heat in the tunnel enters the platform in the air-conditioning season, so that the energy consumption of the environment control system is higher. The shielding door system with the air ports can play a certain role in ventilation in a transition season, but the system has a series of problems that the air port tightness is difficult to guarantee, a plurality of air ports are complicated to control, the operation and maintenance costs are high due to the fact that faults occur easily, and the problem that pollutants in a tunnel enter a station is difficult to solve.

Disclosure of Invention

the utility model aims to solve the technical problem that a shield door end door with ventilation and purification performance is provided.

The technical scheme adopted by the utility model is that the shielding door end door with the functions of ventilation and purification for urban rail transit comprises a door body, a fixed door and an auxiliary window fixed above the door body and the fixed door; the bottom of the fixed door, the lower part of the door body and the auxiliary window are provided with ventilation devices; the ventilation device is connected with the fixed frame through bolts.

The ventilation device comprises a ventilation shutter and a purification and dust removal device; the purifying and dedusting device is arranged on the inner side of the ventilation louver.

The purifying and dedusting device comprises an electrostatic filter screen and a primary filter screen arranged on the side of the tunnel.

The utility model has the advantages that the end door is provided with the opening and is vertical to the piston wind direction, so that the piston wind generated by the train operation can be effectively utilized to ventilate the station; meanwhile, the purification component purifies the piston air, so that inhalable particles in the tunnel and pollutants such as bacteria and metal particles carried by the inhalable particles can be prevented from entering the station, and energy consumption of a station ventilation air-conditioning system can be saved while health of waiting passengers and workers in the station is not influenced.

Detailed Description

The shield door end door with the purifying and ventilating functions of the present invention will be described in further detail with reference to the accompanying drawings and the following detailed description:

As shown in fig. 1 to 4, the shield door end door with ventilation and purification functions for urban rail transit of the present invention comprises a door body 4, a fixed door and an auxiliary window fixed above the door body and the fixed door; the bottom of the fixed door, the lower part of the door body and the auxiliary window are provided with ventilation devices; the ventilation device is connected with the fixed frame 5 through bolts and is arranged on the door body 4. The ventilation device comprises a secondary window ventilation device 1, a fixed door ventilation device 2 and an end door ventilation device 3.

The ventilation device comprises a ventilation shutter 101 and a purification and dust removal device 102 which can be opened and adjusted, and the purification and dust removal device is arranged on the inner side of the ventilation shutter; the purposes of ventilating and changing the station by utilizing piston wind are achieved by opening, closing and adjusting the controllable ventilation louver 101 and matching with a tunnel ventilation system mode.

the purifying and dedusting device 102 comprises an electrostatic filter screen 201 and a primary filter screen 202 installed on the side of the tunnel. In order to ensure the dust removal and purification effect and the air quantity passing through the ventilation device, the dust removal and purification device with relatively small resistance is required. By comparison, an electrostatic filtration device was selected. In order to ensure the service life of the electrostatic filtering device, a primary filter screen is additionally arranged on the side close to the tunnel. The air in the tunnel is firstly filtered to remove larger dust through the primary filter screen 202, so that the service life of the device is ensured; then, the fine particles and the metal particles are purified by passing through the electrostatic filter 201, so that the health of the personnel in the station is ensured.

The utility model discloses rail transit has the function realization of ventilation and purification performance's shield door end door:

When the enthalpy of outdoor air is higher than that of return air in summer, too much outdoor fresh air is introduced to improve the energy consumption of station air conditioners, train braking heat enters the station to increase the energy consumption of the station air conditioners, and therefore ventilation shutters above the end doors of the platform shielding doors, the bottoms of the end door fixing doors and the bottoms of the end doors and a purification and dust removal device are closed, and the station utilizes an air conditioning system to ensure that the environmental temperature of the station is comfortable.

when the enthalpy of outdoor air is less than or equal to the enthalpy of return air of a station and the temperature of outdoor air dry balls is greater than the winter working condition conversion temperature, ventilation shutters and purification and dust removal devices above the end door of the platform shielding door, at the bottom of the fixed door at the bottom of the end door and at the bottom of the end door are opened, and piston air is fully utilized for ventilation.

And (3) reducing the outdoor temperature to be lower than the working condition conversion temperature in winter, namely, closing the ventilation shutters and the purification and dust removal devices above the platform shielding door end door, at the bottom of the end head end door fixed door and at the bottom of the end door so as to avoid the temperature of the station from being lower than the comfortable requirement.

in the transition season, outdoor air temperature is usually lower than the in-station air temperature, rationally optimize station platform screen door system, adopt reasonable device, introduce the station with outdoor air and carry out ventilation and air change and purify piston wind simultaneously, make full use of piston wind carries out free ventilation and air change in order to save ventilation air conditioner energy consumption, the health of the interior staff of waiting passenger and station has been guaranteed along with piston wind entering station to pollutant in the tunnel also, has important energy-conserving prospect and industrialization prospect. By consulting data and reasonably utilizing piston wind for ventilation in transitional seasons, each station can save electricity by about 10 thousands of kWh every year, and a city operating 4 subway lines can save electricity by about 800 thousands of kWh every year by taking 20 stations in each line as an example, so that the energy-saving effect is very obvious.
