Mural painting is all arranged at Qi Sibi and top, does not possess air diffuser mounting condition；And in grottoes, air parameter changes and in the body of precipice for a long time
Rock water capacity changes, and causes moisture and salt regime in mural painting supporting layer and ground battle layer, causes the various salt damage of mural painting, the ventilation of conventional design
System will change wind environment in grottoes, thus activates mural painting salt damage.
This kind of grottoes in Mo kao grotto at Dunhuang, rainy day air highly humid air penetrates into grottoes makes mural painting impaired；Dioxy in travel surge phase grottoes
Changing concentration of carbon drastically to raise, air quality is low.Therefore, it is badly in need of a set of emchanical air supply system, meets grottoes air-conditioning requirement condition
Under, maintain wind environment in grottoes, reduce mural painting salt damage risk.
Utility model content
The purpose of this utility model is to provide a kind of grottoes ruins pressurization moisture resistance ventilating system, asks solving above-mentioned technology
Topic.
For realizing object above, this utility model adopts the following technical scheme that:
A kind of grottoes ruins pressurization moisture resistance ventilating system, including blower fan, fan frequency converter and some air outlets；Blower fan becomes
Frequently device connecting fan, for controlling the rotating speed of blower fan；The air outlet of blower fan connects some arms by blast main；Uniformly pacify on arm
Equipped with some air outlets；Described air outlet is that floor air supply register, blast main and arm are all arranged in below floor.
Further, baroceptor and controller are also included；Each air outlet be provided with one for control its open or
The electromagnetic air valve closed；Baroceptor is arranged in grottoes, for detecting the atmospheric pressure in grottoes；The output of baroceptor
End connects the input of controller；The outfan connecting fan converter of controller and all electromagnetic air valves.
Further, controller is by wired mode or wireless mode connecting fan converter and all electromagnetic air valves.
Further, described some arms parallel are arranged.
Further, described some arms are three.
Further, each arm arranging 5 and goes out wind velocity less than 0.2m/s, air output is less than 50m3The air outlet of/h.
Further, the entrance of each arm is provided with an air-valve.
Further, arm and each air outlet installation place are provided with wind speed measurement mouth.
Relative to prior art, this utility model has the advantages that
This utility model is empty in order to solve in these type of grottoes rainy day air highly humid airs such as Mogao Grottoes penetrate into grottoes and travel surge phase cave
The problem of gas low quality, it is provided that a kind of ventilating system, it forms pressure-fired in can making grottoes, prevents rainy day highly humid air from oozing
Enter, and input fresh air for grottoes, in improving grottoes, visit environment；This utility model uses floor blowing, does not affect whole
The pattern of grottoes top layer；Use base plate air outlet, control each air outlet and go out wind velocity less than 0.2m/s, thus i.e. meet required
Air output, wind environment in grottoes was not caused large disturbances.There is good prospect of the application, can be widely used in Dunhuang not
The grottoes environment that high cave etc. are higher to air-conditioning requirement in grottoes.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model pressurization anti-steam infiltration ventilating system.
Detailed description of the invention
Referring to shown in Fig. 1, this utility model one grottoes ruins pressurization moisture resistance ventilating system, including blower fan 1, blower fan
Converter 2, airduct, air outlet 4, baroceptor 5 and controller 6.
Fan frequency converter 2 connecting fan 1, for controlling the rotating speed of blower fan 1, and then controls the air output of blower fan 1.Blower fan 1
Air outlet connects three arms being arranged in parallel 7 by blast main 3；5 air outlets 4 are uniformly installed on each arm 7.Three
The entrance of individual arm 7 is each provided with an air-valve, for controlling the air output of three arms, makes the air output of three arms balance.
In this utility model, air outlet uses floor air supply register, and each air outlet goes out wind velocity and is less than 0.2m/s, and air output is less than
50m3/h.Blast main and arm are all arranged in below floor, do not affect the roof environment of whole grottoes.Each air outlet is provided with
One for controlling its electromagnetic air valve opened or close.Arm and each air outlet installation place are provided with wind speed measurement mouth,
For monitoring wind speed, the used time does not uses rubber closure to clog.
Grottoes are disposed with baroceptor 5, for detecting the atmospheric pressure in grottoes.The outfan of baroceptor 5 connects control
The input of device 6 processed；The outfan of controller 6 is by wired mode or wireless mode connecting fan converter 2 and all electromagnetism
Air-valve.
This utility model one grottoes ruins pressurization moisture resistance ventilating system, during work: blower fan 1 and fan frequency converter 2 work,
The wind that blower fan 1 is sent arrives each air outlet through blast main and arm；During original state, on each arm, only three air outlets are opened；
The atmospheric pressure in grottoes monitored by baroceptor 5, and at detected value less than when setting pressure limit, controller becomes by controlling blower fan
Frequently device 2 is to control the rotating speed of blower fan 1, and then increases air output, and one air outlet not worked of controller control simultaneously is opened and carried out
Air-supply, increases air output；Until the detected value of baroceptor 5 is positioned at the pressure limit of setting.
This utility model sets pressure limit as pressure-fired, prevents rainy day highly humid air from permeating to grottoes；Meanwhile, in the travel surge phase,
Increase the exchange of grottoes inner air and outer air, quickly reduce carbon dioxide content in grottoes, improve visitor and visit environment.
This utility model ventilating system, under satisfied design requirement condition, does not allow wind environment in cave was caused large disturbances.Utilize wind
Machine converter and air-valve strictly control air quantity, utilize air quantity monitoring mouth feedback air quantity information, select the little air quantity of many air outlets to blow,
Ensure that each air outlet goes out wind velocity and is less than 0.2m/s, thus i.e. meet required air output, wind environment in grottoes is not caused
Cross large disturbances.
This utility model uses novel structure and rational draft type, reaches the air-supply of grottoes micro-disturbance, has before well using
Scape, can be widely used in the grottoes environment higher to air-conditioning requirement in grottoes such as Mo kao grotto at Dunhuang.
