Problems solved by technology
There are some shortcomings in the existing spray towers: the multi-stage spraying of the same spray tower all uses the absorption liquid of the same liquid storage tank. After working for a period of time, the solute content in the absorption liquid becomes higher, which causes the absorption rate of exhaust gas to increase. In addition, in order to ensure high absorption efficiency, the absorption liquid with medium content of solute needs to be discharged, and then new absorption liquid is added, which causes waste of absorption liquid and increases the subsequent absorption liquid. processing cost

Embodiment 1
[0030] An embodiment of the shower device of the present invention, such as Figure 1~3As shown, it includes a spray tower 1, which is provided with three first-stage purification equipment 2, second-stage purification equipment 21 and third-stage purification equipment 22 arranged up and down in the spray tower 1, and each purification equipment includes a spray Assemblies, the packing layer and the sump for collecting the absorption liquid are fixed in sequence under the spray assembly. The top of the sump is provided with an opening, and the side wall of the sump is closely attached to the inner wall of the spray tower 1. In the sump There is a vent pipe 10 for the waste gas below to pass through and is placed vertically. A water blocking cap 101 is provided above the upper port of the vent pipe 10. The water blocking cap 101 prevents liquid from flowing into the vent pipe 10. The bottom of each sump passes through The drain pipe is connected with a liquid storage tank 3; ...

The invention discloses a counter flow type multistage spray device. At least N purification devices are sequentially arranged in a spray tower up and down, each purification device comprises a sprayassembly, a packing layer and a liquid collecting tank for collecting an absorption liquid are sequentially fixed below each spray assembly, a vent pipe waste gas inlet allowing gas on the lower sideto pass is formed in each liquid collecting tank, the upper port of each vent pipe is higher than the bottom of the corresponding liquid collecting tank, and the bottom of each liquid collecting tankis connected with a liquid storage box through a drain pipe; n liquid storage boxes are arranged, a liquid inlet and a liquid outlet are formed in each level of liquid storage box, liquid inlets in two adjacent layers of liquid storage boxes are communicated with the drain pipes at the bottoms of the liquid collecting tanks of two adjacent layers of purification devices respectively, and liquid outlets in two adjacent layers of liquid storage boxes are communicated with the spray assemblies of two adjacent layers of purification devices respectively. The spray device can significantly improvethe waste gas purification efficiency on the premise that the cost is reduced; besides, the spray device adopts modular design and can be equipped by oneself as required.
Description
technical field [0001] The invention belongs to the technical field of exhaust gas treatment equipment, and in particular relates to a countercurrent multi-stage spraying device. Background technique [0002] At present, spray towers are widely used to purify waste gas. There are some shortcomings in the existing spray tower: the multi-stage spraying of the same spray tower all uses the absorption liquid of the same liquid storage tank. After working for a period of time, the solute content in the absorption liquid becomes higher, which causes the absorption rate of waste gas In addition, in order to ensure high absorption efficiency, the absorption liquid with medium content of solute needs to be discharged, and then new absorption liquid is added, which causes the waste of absorption liquid and improves the subsequent absorption liquid. processing costs. [0003] Therefore, it is necessary to design a counter-flow multi-stage spraying device to ensure the improvement of ...
