Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of purifying fresh air system for toll booth, can solve toll booth air-polluting problem, effectively purifies air, and provides and meets the new wind that health requires.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of purifying fresh air system for toll booth, comprise air main, the air outlet of air main stretches in tollbooth, in the air outlet one side pipe road of air main, electric closed valve is installed, new wind pretreatment section is communicated with the air inlet of air main by airduct and new wind-heat wet process section;
In new wind pretreatment section, new wind pretreatment shell air inlet place ecto-entad is provided with roughing efficiency air filter, medium effeciency filter and active carbon filter successively;
New wind-heat wet process intersegmental part is separated into the cold and hot process chamber, transmission cavity and the wet process chamber that interconnect, and wet process chamber is communicated with air main.
Interior machine and the auxiliary electrical heater pipe of wind-cooling type heat pump unit are installed in cold and hot process chamber further.
Further, the breeze fan with driving motor is installed in transmission cavity, the air outlet of breeze fan is communicated with wet process chamber.
Further, high-medium efficient filter, water fender and humidifier jet pipe are installed in wet process chamber.
Further, the entrance point of new wind pretreatment section is provided with the rainproof elbow with fly net.
Further, airduct inside is provided with air pipe check valve.
Further, the space of the new wind pretreatment section of medium effeciency filter both sides is communicated with the first pressure difference switch, and the wet process cavity space of high-medium efficient filter both sides is communicated with the second pressure difference switch.
Air outlet is preferably slot outlet.
Further, on air main, be also communicated with many branch wind pipes.
Further, air outlet is positioned at tollbooth inner and upper.
The purifying fresh air system for toll booth that the utility model provides, beneficial effect is as follows:
1, by new wind pretreatment section and new wind-heat wet process section, air is processed to rear formation and meet the new wind that health requires, again new wind is delivered in tollbooth, for tollbooth provides fresh air, maintain internal positive pressure and prevent outside contamination air penetration, can solve toll booth air-polluting problem, effectively purify air, provide and meet the new wind that health requires.
2, simple in structure, easy for installation.
3, good filtration effect, middle high efficiency particulate air filter can catch the more than 1 micron grit of particle diameter in air, and intercepting efficiency is up to 99%, and active carbon filter can play the effect of the waste gas of absorption petroleum product burning generation, as sulfur dioxide, carbon monoxide etc.
4, air outlet is positioned at the design of tollbooth inner and upper, and new wind pours in tollbooth from top, forms " air curtain ", has further effectively completely cut off the contaminated air of outside high dust-laden, high exhaust gas discharge, has improved new wind efficiency.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model comprises air main 1, the air outlet 2 of air main 1 stretches in tollbooth 3, in the air outlet 2 one side pipe roads of air main 1, electric closed valve 4 is installed, and new wind pretreatment section 5 is communicated with the air inlet of air main 1 by airduct 6 and new wind-heat wet process section 7;
In new wind pretreatment section 5, new wind pretreatment shell air inlet place ecto-entad is provided with roughing efficiency air filter 8, medium effeciency filter 9 and active carbon filter 10 successively;
New wind-heat wet process section 7 inside are separated into the cold and hot process chamber 11, transmission cavity 12 and the wet process chamber 13 that interconnect, and wet process chamber 13 is communicated with air main 1.
Interior machine 14 and the auxiliary electrical heater pipe 15 of wind-cooling type heat pump unit are installed in cold and hot process chamber 11.
Breeze fan 17 with driving motor 16 is installed in transmission cavity 12, and the air outlet of breeze fan 17 is communicated with wet process chamber 13.
High-medium efficient filter 18, water fender 19 and humidifier jet pipe 20 are installed in wet process chamber 13.
The entrance point of new wind pretreatment section 5 is provided with the rainproof elbow 21 with fly net.
Airduct 6 inside are provided with air pipe check valve 22.
The space of the new wind pretreatment section 5 of medium effeciency filter 9 both sides is communicated with the first pressure difference switch 23, and 13 spaces, wet process chamber of high-medium efficient filter 18 both sides are communicated with the second pressure difference switch 24.
Air outlet 2 is slot outlet.
On air main 1, be also communicated with many branch wind pipes 25.
Air outlet 2 is positioned at tollbooth 3 inner and upper.
The course of work of the present utility model is as follows:
Air is cleaned into and meets the new wind that health requires after new wind pretreatment section 5, airduct 6 and new wind-heat wet process section 7, again new wind is delivered in tollbooth, for tollbooth provides fresh air, can solve toll booth air-polluting problem, effectively purify air, provide and meet the new wind that health requires.
Middle high efficiency particulate air filter in new wind pretreatment section 5 can catch the more than 1 micron grit of particle diameter in air, and intercepting efficiency is up to 99%, and active carbon filter can play the effect of the waste gas of absorption petroleum product burning generation, as sulfur dioxide, carbon monoxide etc.
According to environment at that time, optionally interior machine 14, auxiliary electrical heater pipe 15, humidifier jet pipe 20, the water fender 19 of the wind-cooling type heat pump unit in new wind-heat wet process section 7 are processed the air after preliminary purification.
