Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

As shown in fig. 1, a multistage high-efficient defogging device, including tower body 1, tower body 1 top is equipped with gas outlet 11, and the department is equipped with liquid outlet 13 at the bottom of the tower, and its lateral wall bottom is equipped with an air inlet 12, is provided with a plurality of defroster 2 from top to bottom in this tower body 1 in order, the preferred silk screen defroster that is of defroster 2. Every two adjacent demisters 2 are distanced. VOCs waste gas gets into in tower body 1 by air inlet 12, and VOCs waste gas rises the in-process and passes through a plurality of defroster 2 in order, and wherein the mist that contains collides with defroster 2 and attaches to defroster 2 on, from this with the separation of VOCs gaseous phase composition, the mist is finally converged and is formed the water droplet. In order to derive the water droplet that will attach to on defroster 2 fast, in this design, the conical structure of defroster 2 adoption inversion, the kuppe 3 that upper and lower end difference is open is installed to 2 bottoms of each defroster, and annular gap is left to 3 upper end opening borders of this kuppe and 2 lateral walls of defroster to guarantee that the water droplet smoothly flows into in the kuppe 3 on the defroster 2. Attached water droplet flows to the kuppe 3 along defroster self on defroster 2 in to through the 2 center departments of defroster of kuppe 3 inflow below positions, and with this below position 2 attached water droplet jointly through this below position 2 behind the kuppe 3 of defroster 2, by the tower body 1 central point position flow down, finally by the discharge of liquid outlet 13, guaranteed each defroster permeability, and then guarantee the gaseous trafficability characteristic of VOCs. In this embodiment, the air guide sleeve 3 is an inverted conical structure concentric with the tower body 1. This structure guarantees that the water droplet is by 3 when discharging downwards of kuppe, and the rivers direction is vertical or towards tower body central direction, and the water that also separates is located to collect downwards by the tower body center, has reduced its and VOCs waste gas contact probability and area, has guaranteed VOCs waste gas rising speed, and then improves VOCs waste gas and 2 collision effects of defroster, improvement separation effect. The concrete mounting structure of kuppe 3 does, and 2 bottom integrated into one piece of defroster are equipped with horizontal installation portion 21, and the mounting hole has been seted up to horizontal installation portion 21 center department, 3 upper end opening part of kuppe is equipped with fixed plate portion 31, as shown in fig. 2, fixed plate portion 31 center department sets up the fixed orifices that corresponds with the mounting hole, and the fixed orifices matches has the bolt-nut structure, and the bolt passes fixed orifices and mounting hole to lock through the nut, from this with fixed plate portion 31 and horizontal installation portion 21 fixed connection. In this embodiment, the fixing plate 31 is vertically provided with a plurality of guiding holes 32 for water drops to pass through, so as to guide the water drops into the air guide sleeve 3.

In the design, the top of the inner cavity of the tower body 1 is concentrically provided with a water pipe 4 which is bent into a circular ring shape, and the water pipe 4 is provided with a plurality of nozzles 5 downwards. When needing to wash defroster 2, the external high pressure water source of 4 water inlets of water pipe, 5 play water of shower nozzle are to 2 backwash of defroster, improve 2 permeability of defroster.
