Description
Technical field
The present invention is a kind of based on TiO2The device of nano pipe photochemical catalyst degraded VOCs gases, belongs to air purifying process neck
Domain.
Background technology
VOCs (volatile organic compounds) volatile organic matter, is often referred to readily volatilized at normal temperatures
Organic matter.More typical has benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, ketone etc..VOCs is a class to human body and ring
The harmful gas in border, and originate and its extensive, for example, industrial waste gas, vehicle exhaust, indoor hardware fitting, photochemical fog etc..
And the method for main processing VOCs gases is absorption at present, such as runner type is adsorbed, cylinder type absorption etc., but this method can not
It is inherently eliminated VOCs gases.
Therefore, processing degraded VOCs gases are an important at present efforts at environmental protection.Urged using titania nanotube light
Changing degraded VOCs gases has its superiority, can generate CO2Deng inorganic matter, it can greatly reduce the danger to environment and human body
Evil.
The content of the invention
The present invention devises a kind of based on TiO2The device of nano pipe photochemical catalyst degraded VOCs gases, to solve above-mentioned background
The problem of being mentioned in technology.Device includes：Fibrous filter net（1）, air-introduced machine（2）, closed degraded storehouse（3）, load TiO2Nanometer
The dividing plate of pipe（4）, UV-LED lamps（5）, pressure transducer（6）, VOCs sensors（7）, PLC（8）, blower fan
（9）, Adsorption Concentration area（10）, heater（11）, ventilating fan（12）, one-way flow pipe（13）.
As a kind of preferred scheme, the present apparatus takes periodic duty：By " closed degraded storehouse（3）Interior TiO2Light is urged
Change four times-Adsorption Concentration of degraded area（10）Four times-Adsorption Concentration of zeolite adsorption area（10）Zeolite desorption concentration " is considered as a week
Phase, circular flow can improve the utilization rate of device.
It is used as a kind of preferred scheme, TiO2Nano tube supported dividing plate internally（4）Positive and negative, and closed degraded storehouse
（3）Inner surface, while in closed degraded storehouse（3）Four UV-LED lamps of interior installation（5）, so as to utilize the TiO of large area2
Nanotube and plentiful illumination are fully degraded VOCs gases.
It is used as a kind of preferred scheme, pressure transducer（6）With PLC（8）Connection, storehouse internal pressure it is powerful in
During 0.3 ~ 0.5 MPa of given threshold, air-introduced machine is closed（2）Switch, stop air inlet.
As a kind of preferred scheme, using PLC（8）Control device, intelligent control reduces manpower.
Brief description of the drawings
Fig. 1：Based on TiO2The device of nano pipe photochemical catalyst degraded VOCs gases.
Fig. 2：Load TiO2The dividing plate of nanotube.
Fig. 3：Load TiO2The degraded storehouse inner surface of nanotube.
Specific implementation method
VOCs gases pass through fibrous filter net（1）The impurity such as dust in air are filtered out, air-introduced machine is then sent through（2）, via list
Enter closed degraded storehouse to flow duct（3）, in VOCs enters to put in storage, it is attached to TiO2On nanotube, in UV-LED lamps（5）Irradiation
Under, TiO2Electron hole pair is produced inside nanotube, redox reaction occurs for the VOCs gases for being attached to surface, generates CO2Deng
Inorganic matter, now, by pressure transducer（5）Internal pressure is detected, when pressure values are more than 0.5 MPa of given threshold, can be compiled by PLC
Range controller（8）Control air-introduced machine（2）Switch, stop air inlet.By VOCs sensors（7）Detect now closed degraded storehouse（3）
The concentration of interior VOCs gases, is set to initial value, closed degraded storehouse（3）The concentration of interior VOCs gases reaches the 20% of initial concentration
When, PLC（8）To control blower fan（9）Switch, gas is sent to Adsorption Concentration area via blast pipe（10）,
The 20%VOCs not being degraded is by zeolite adsorption, CO2By Adsorption Concentration area（10）And ventilating fan（12）Discharge, so circulates four
After secondary, PLC（8）Control heater（11）Open, ventilating fan（12）Close, one-way flow pipe（13）Open,
200 DEG C of heating, the VOCs after desorption concentration passes through one-way flow pipe（13）Into closed degraded storehouse（3）, by VOCs sensors（7）
When detecting VOCs concentration for 0 ppm, PLC（8）Blower fan is controlled again（9）Open, one-way flow pipe（13）Close,
Gas passes through ventilating fan（12）Manpower, fully intelligent control, degraded are saved in discharge, such a cycle, circular flow.
