Embodiment 1

[0038] In a university cafeteria, an electrostatic oil fume removal system was used for flue gas treatment. When the moisture in the oil fume is high in winter, explosion venting often occurs, which affects normal use, and the VOC emissions of the flue gas often exceed the standard. In order to ensure stable use and solve the problem of excessive VOC emissions, the equipment of the present invention is used for transformation; the original smoke collection hood and front pipes are retained, the electrostatic oil fume removal system is removed, and a vertical U-shaped cooling pipe is added outdoors, which is made of tap water. The cooling water source, the control valve is set on the ground, the water valve is opened to control the water flow speed when the equipment is started, and the cooling water collected by the sump is used for cleaning and sanitary water.

[0039] Such as figure 1 and 3 As shown, a treatment equipment for polymorphic organic compound pollutants includes...

Embodiment 2

[0059] In a barbecue restaurant, the original flue gas treatment uses an electrostatic oil fume removal system plus plasma removal of VOC, which requires a large investment, high operating costs, and insufficient processing capacity. When 50% of the barbecue seats are activated, the surrounding residents can still accept them. When the seats are more than 70%, the residents react strongly. In order to solve the problem of disturbing the residents, the equipment of the present invention is used to carry out the transformation of flue gas treatment; the original fume collecting hood and the front pipe are retained, the electrostatic oil fume removal system is removed, and a vertical I-shaped cooling pipe is added outdoors, and tap water is used as the cooling water source. The control valve is set on the ground. When the equipment is started, the water valve is opened to control the water flow speed. The cooling water collected in the sump is used for cleaning and sanitation.

Embodiment 3

[0080] A moxibustion physiotherapy shop originally used an electrostatic oil fume removal system for smoke control, which required a large investment and high operating costs, and it could not solve the smell of moxibustion. There are many kinds of liquid-solid gaseous VOCs in moxibustion smoke. The most odorous ones are eucalyptol and camphor. At the temperature of smoke treatment, camphor is in liquid state and camphor is in solid state. A large number of other VOCs are in gaseous state and have a certain smell. In order to solve the problem of disturbing the residents, the equipment of the present invention is used to carry out the transformation of flue gas treatment; the original fume collecting hood and the front pipe are kept, the electrostatic oil fume removal system is removed, and a vertical U-shaped cooling pipe is added outdoors, and tap water is used as the cooling water source. The control valve is set on the ground. When the equipment is started, the water valve ...

Abstract

The invention belongs to the technical field of environmental protection, and relates to a treatment device and method for polymorphic organic composite pollutants. The device comprises an exhaust fume collecting hood, a cooling pipeline, a flue gas liquid-solid capture device, an induced draft fan, a flue gas adsorption device and a chimney. The outer wall of tap water is used for dripping and cooling, the flowing water amount is adjusted by adjusting the liquid level height of an annular dripping groove, water is evaporated to reduce the temperature of a pipe wall, a high-power circulating pump is not needed. Compared with a spraying type cooling mode and a sleeve type cooling mode, the invention has the advantage of saving cost and is flexible and convenient to use and convenient to maintain; flue gas cooling treatment is carried out in front of the flue gas liquid-solid capture device, so that more gaseous VOCs are changed into liquid-solid VOCs, then the flue gas liquid-solid capture device blocks, captures and absorbs solids and liquid, the problem of liquid-solid pasting and blocking of a subsequent flue gas adsorption device is solved, an adsorption function of an adsorption material is brought into full play, and adsorption pressure can be effectively reduced; Service life of the adsorption material is prolonged, operation cost is reduced and clean emission can be realized.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a treatment equipment and method for polymorphic organic compound pollutants. Background technique [0002] At present, ozone-type smog is becoming more and more serious, and the main cause of ozone-type smog is VOC emissions. The composition of VOC is very complex, resulting in vastly different vaporization point, liquefaction point, and freezing point. Because the generated droplets and particles are very small, it is very difficult to control. There are often three states of composite smoke, and many pollutants are very toxic. carcinogenic substances. [0003] In the prior art, there are many treatment methods, such as plasma method, direct adsorption method, and electrostatic oil fume removal method. The material is quickly blocked by the surface, easily loses its adsorption capacity, and has a short service life; electrostatic adsorption can on...
