Abstract
The invention provides an adsorption device for a cavern. Humiture and carbon dioxide sensors based on wireless Zigbee communication protocol are arranged in the cavern, and periodically transmit environmental data to a Zigbee aggregation node; the aggregation node uploads the environmental data to a start controller of the adsorption device; when the relative humidity in the cavern exceeds 62 percent, or the concentration of carbon dioxide exceeds 1500 ppm, the start controller starts up the adsorption device to work; an air compressor of the adsorption device starts to work, so as to suck humid air or high-concentration carbon dioxide in the cavern, humid air or high-concentration carbon dioxide firstly passes through a drying tower after being compressed, excessive moisture in air is taken away, and a solenoid valve 2 is opened to discharge dry air into the cavern; when the solenoid valve 2 is not opened, dry air enters a carbon dioxide adsorption tower and is adsorbed by an adsorbent, and then air with low-concentration carbon dioxide is discharged into the cavern to enable the humidity and the carbon dioxide concentration in the cavern to be kept stable.
Description
Technical field:
The present invention relates to historical relic's protection field, particularly grottoes protection field.
Background technology:
World-renowned Heritage area Mo kao grotto at Dunhuang is located in innerland, Gobi desert, is Chinese and even worldwide largest, rich connotation, art is consummate, preserves rock cave that is good, that have the greatest impact.The protection of Mo kao grotto at Dunhuang culture rarity is obtained always to the great attention of the Chinese government.At rainy weather, outside ambient air is in high humility, along with the air exchange inside and outside grottoes, causes cave humidity to raise, thus causes the damage of mural painting; CO
2mural painting can be caused to be in a sour environment, potential threat is caused to mural painting, painted sculptures protection.
Through the long-term environmental monitoring to Mogao Grottoes grottoes, the upper limit of grottoes relative humidity is 62%, and the upper limit of gas concentration lwevel is 1500ppm.
Adsorbent is the solid matter that effectively can adsorb wherein some composition from gas or liquid.Adsorbent generally has large specific surface, suitable pore structure and surface texture, not with adsorbate or medium generation chemical reaction, has good mechanical strength.
Summary of the invention:
A kind of adsorbent equipment for grottoes, it is characterized in that: described adsorbent equipment is made up of air compressor, magnetic valve 1, drying tower, magnetic valve 2, carbon dioxide adsorption tower and magnetic valve 3, humid air in grottoes or the high carbon dioxide of concentration enter described drying tower after described air compressor compression, moisture too much in air is sucked away, open magnetic valve 1, dry air is discharged in grottoes, magnetic valve 2 is not opened, dry air can enter carbon dioxide adsorption tower, after adsorbent, the air of low carbon dioxide concentration is discharged in grottoes, the humidity based on Zigbee communication agreement and carbon dioxide sensor cordless communication network is arranged in grottoes, described regular sensor is transferred to the start-up connector of adsorbent equipment environmental data, when the relative humidity in grottoes more than 62% or gas concentration lwevel more than 1500ppm, described start-up connector starts described adsorbent equipment, the described air compressor of described adsorbent equipment starts to start, humid air in grottoes or the high carbon dioxide of concentration are inhaled into, first through described drying tower after overcompression, moisture too much in air is sucked away, open described magnetic valve 2, dry air is discharged in grottoes, described magnetic valve 2 is not opened, dry air can enter adsorption tower described in carbon dioxide, after adsorbent, the air of low carbon dioxide concentration is discharged in grottoes, the humidity in grottoes and gas concentration lwevel is made to keep stable.
Described cordless communication network is made up of wireless humiture sensor, wireless carbon dioxide sensor, wireless Zigbee aggregation node and F5 communication module, described wireless humiture sensor and described wireless carbon dioxide sensor are regularly uploaded to described Zigbee aggregation node environmental data, and aggregation node was uploaded to the described F5 communication module of adsorbent equipment start-up connector every one minute sensor information.
Described start-up connector comprises a TMS320F28335DSP chip.
Accompanying drawing illustrates:
Fig. 1 initiatively adsorbent equipment system architecture always schemes
Fig. 2 adsorbent equipment figure
Detailed description of the invention:
Initiatively adsorption system is formed primarily of wireless humidity sensor (1), wireless CO2 sensor (2), aggregation node (3), adsorbent equipment start-up connector (4) and adsorbent equipment (5) as shown in Figure 1.
Adsorbent equipment is made up of air compressor (1), magnetic valve 1 (2), drying tower (3), magnetic valve 2 (4), carbon dioxide adsorption tower (5), magnetic valve 3 (6) as shown in Figure 2.
Wireless humidity sensor (1), wireless carbon dioxide sensor (2), wireless Zigbee aggregation node (3) composition cordless communication network.Humidity in the grottoes that sensor collects and carbon dioxide information are uploaded to wireless Zigbee aggregation node (3).
Wireless Zigbee aggregation node (3) every one minute the information transmission of sensor to the F5 communication module of adsorbent equipment start-up connector (4).
F5 communication module changes into serial signal wireless signal, and serial signal is directly connected with the control chip of start-up connector.
When the humidity in grottoes more than 62% or gas concentration lwevel more than 1500ppm, controller (4) automatically start adsorbent equipment (5) work.
The air compressor (1) of adsorbent equipment starts to start, humid air in grottoes or the high carbon dioxide of concentration are inhaled into, first through drying tower (3) after overcompression, moisture too much in air is sucked away, open magnetic valve 2 (4), dry air is discharged in grottoes.
Magnetic valve 2 (4) is not opened, and dry air can enter carbon dioxide adsorption tower (5), and after adsorbent, the air of low carbon dioxide concentration is discharged in grottoes.
When the relative humidity in grottoes drops to less than 30%, gas concentration lwevel drops to below 600ppm, and start-up connector stops adsorbent equipment work.
More than that the better enforcement of software and hardware of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent distortion or replace all are included in the scope that the application's claim limits.
