SITE REMEDIATION Technical Field The present invention relates to waste gas treatment devices, and more specifically, to a mobile modular treatment device for organic waste gas in site remediation. Background With the acceleration of urbanization, large numbers of polluting enterprises have been moved out of the urban areas of city centers. Additionally, the relocation, shutdown or closure of industrial enterprises has left behind a large number of various kinds of complex polluted sites. Such sites typically experience substantial loss of value stemming from problems such as soil pollution, groundwater pollution, wall and equipment pollution, waste pollution and the like. A large number of polluted sites (also known as "brownfield sites") are the byproduct of industrial change and urban expansion. These polluted sites bring environmental and health risks, and hinder urban construction and local economic development. The solution is to remediate the sites. Remediation efforts are typically focused around industrial sites like petroleum, chemical, coking and so on, which are mainly caused by organic pollution. Pollutants are featured with organic solvents, such as compounds of benzene, halogenated hydrocarbons and petroleum hydrocarbons. The above-mentioned polluted sites will produce organic waste gas during the remediation process. The organic waste gas may contain not only organic pollutants in high concentrations (such as volatile organic compounds (VOCs)), but also smoke (powder), oil, acidic and malodorous substances (such as HS, SO, NOx), and have the characteristics of high temperature, high CO content, and complex composition. Summary The objective of the present invention is to provide a mobile modular treatment device for organic waste gas in site remediation, which can carry out waste gas treatment while in motion according to actual needs, which is convenient, fast and efficient. To achieve the above objective, the present invention provides the following technical

The gas cooling system is provided outside the gas intake pipe. The rear end of the gas intake pipe is connected to the filter box. A multi-stage filter screen is provided in the filter box, and an outlet of the filter box is connected to a gas inlet of the spraying device through a gas pipeline. The spray head and a spray liquid distributor are provided in the spraying device. The spray head and the spray liquid distributor are connected to the spray water tank. The spray liquid distributor is provided with a solenoid valve. A gas outlet of the spraying device is connected to the deep dehumidification device. The deep dehumidification device 1s connected to the incineration system. An incinerator is provided in the incineration system, and the incineration system is connected to the exhaust funnel through the induced draft fan.
The gas intake pipe, the gas cooling system, the filter box, the spraying device, the deep dehumidification device, the incineration system, the induced draft fan, and the exhaust funnel are integrated on a mobile platform formed by a vehicle or a ship. Further, the gas cooling system is provided outside the gas intake pipe, and the temperature of the waste gas in the waste gas-collecting pipe is reduced by external wind force. Further, the multi-stage filter screen is provided in the filter box. The multi-stage filter screen includes a coarse layer, a medium layer, and a fine layer, and is made of metal wire mesh. If the dust concentration in the inlet gas in front of the filter box is too high, i.e., more than 1 g/m’, a pre-dedusting device, such as a cyclone dedusting device is added in front of the filter box. Further, the spraying device has an effective height of 2.5-6 m, and the gas has a rising speed of 0.6-1.0 m/s in the spraying device with a resident duration of about 4-10 s. Further, 2-3 layers of the spray heads are provided inside the spraying device with 0.5-
0.8 m apart from each layer; each layer of the spray heads is supplied by a separate water pump with a spray intensity of 1-4 L liquid/m? waste gas; the spray water tank is provided at the bottom of the spraying device, which is recycled after being regularly replenished with water and cleaned, and which is regularly emptied to replace fresh water. The drainage is transported as waste water to a sewage treatment device nearby
-3- for treatment.
Further, a filler supporting frame is provided in the spraying device, a perforated supporting plate is provided on the filler supporting frame, the perforated supporting plate is filled with a filler having a filling thickness of 0.4-1.0 m.
The filler is a plastic hollow ball with a diameter of 25-50 mm.
The type and thickness of the filler are determined according to the amount of waste gas, the nature and concentration of pollutants, etc.
Generally, for the pollutants with complex compositions and high concentrations, the filling diameter is relatively small and the filling thickness is relatively large.
The filler is only filled in the upper part of the spraying device when handling basic or acidic waste gases.
Further, the spraying device is further provided with a gas mist separator, which is located between the uppermost layer of the spray heads and the gas outlet of the spraying device with a thickness of about 0.2-1.0 m.
Further, the spray liquid distributor includes a plurality of outlets.
The plurality of outlets are connected, respectively, to each of the spray heads in different layers, and each layer of the spray heads is provided with an independent solenoid valve.
Further, the deep dehumidification device includes a centrifugal dewatering device and a multi-stage filtration dehumidification device.
Further, the mobile modular treatment device for organic waste gas has a length of 12 m, a width of 2.6 m, and a height of 2.6 m.
Compared with the prior art, the present invention has the following advantages.
The mobile modular treatment device for organic waste gas in site remediation of the invention integrates a gas intake pipe, a gas cooling system, a filter box, a spraying device, a deep dehumidification device, an incineration system, an induced draft fan, and an exhaust funnel on a mobile platform formed by a vehicle or a ship, which can carry out waste gas treatment while in motion according to actual needs, and is convenient, fast and efficient.
