Description
Technical Field
The utility model relates to an air stripping equipment, especially a high-efficient air stripping equipment to volatile organic compounds.
Background
With the rapid development of industrial production, the problem of groundwater pollution in China is increasingly prominent, the supervision of the soil remediation industry is gradually increased along with the guidance of policies in China, and in recent years, the country has come out of a plurality of relevant laws and regulations and regulates the soil remediation industry in China. Soil remediation is necessarily accompanied by groundwater remediation, and the two are closely separable. The field soil has short repair period and high toxicity, and the field needs to be recycled after the repair, so that the conventional method for building the reinforced concrete structure and performing biodegradation cannot meet the market demand of groundwater repair, and the construction before the project of the reinforced concrete structure and the demolition after the project of the reinforced concrete structure increase the investment cost and increase the construction period, and the investment cost is high and the construction period time is long.
China starts late in the field of polluted site remediation, and does not have efficient equipment and related processes at present aiming at the remediation of groundwater and wastewater generated in the soil remediation process of the polluted site. The waste water mainly contains heavy metal pollution, semi-volatile and volatile organic sewage, non-volatile organic sewage, and composite sewage containing silt, large-particle solid and the like. Aiming at the oily semi-volatile and volatile wastewater, a special high-efficiency device with strong pertinence is needed. And technical information of related equipment is not available at present.
SUMMERY OF THE UTILITY MODEL
The utility model discloses an overcome above-mentioned technical problem, provide an efficient air stripping equipment.
The scheme of the utility model is that:
the utility model provides a high-efficient air stripping equipment, includes the casing, the ascending and sewage decline device of air current constitutes, and the top layer of casing is equipped with contaminated water inlet and exhaust hole, connects the inlet tube under the water inlet, and the inlet tube hangs in the top of hydrolock, and the exhaust hole has connect the suction fan, and the casing middle part is equipped with the column plate, and is porose on the column plate, has feed liquor hydrolock and downcomer on every layer of column plate, and the downcomer export of connecting the upper column plate is under feed liquor hydrolock liquid level, and the downcomer mouth that leads to lower floor's column plate is under lower floor's feed liquor hydrolock liquid level, and the casing bottom is equipped with the water storage tank, the downcomer mouth of pipe of casing bottom is under the liquid level of water storage tank, and the water.
The pipeline of the blower is provided with an air heater.
The aforementioned trays are divided into long and narrow loops.
And a nozzle is arranged at the outlet of the water inlet.
Pumping sewage into air stripping equipment from an upper water inlet, then spraying from a nozzle at an outlet of a water inlet, after buffering of a water seal tank, flowing to another water seal tank along a tower plate loop, falling into a next layer along a downcomer until flowing to a water storage tank at the bottom layer, blowing air from bottom to top through a fan, enabling the air to pass through holes in the tower plate, enabling the air not to affect liquid to flow downwards due to the existence of the liquid seal tank, enabling the waste water not to fall from the holes in the tower plate due to blowing of gas, discharging the waste gas from a top exhaust hole at last, and enabling the treated sewage to flow out of a water outlet of the water storage tank. The air stripping equipment can be normal-temperature extraction equipment, and on the basis, an air channel heater is arranged at the clean air inlet, so that the extraction efficiency of volatile and semi-volatile organic components in the polluted water is increased, and the efficiency is higher than that of the original equipment. At the same time, the long and narrow loop on the tray can prolong the contact time of waste water and air.
Advantageous effects
1. The equipment is compact and small in size, is suitable for the characteristic of site repair in China at present, and saves project investment cost.
2. The equipment adopts multi-stage tower plates, scientifically lowers liquid and distributes gas, so that the gas stripping reaction is sufficient.
3. This equipment is further installs hair-dryer and air exhauster additional simultaneously, and the amount of wind that conveniently adjusts the hair-dryer through vector variable frequency motor is slightly greater than the air exhauster for form the cyclone in the casing, produce the effect of high-efficient air stripping, more abundant feasible volatilizable material volatilizees.
4. The equipment further heats the inlet air, so that hotter air is blown into the shell, and the higher temperature is more favorable for volatilizable substances to volatilize.
