FIG. 1 is a schematic structural view of the present invention;
in the figure: 1 desulfurizing tower, 2 spray structures, 3 demisters, 4 thick liquids preparation facilities, 5 demisters wash the structure, 6 retaining structures, 7 gypsum dewatering systems, 8 drainage water tank, 9 waste water treatment structure, 10 second gypsum dewatering systems, 11 external water pipes, 12 rows of outlet pipes, 13 connection branch pipes.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in figure 1, the water balance adjusting system of the desulfurizing tower comprises a desulfurizing tower 1, a spraying structure 2 and a demister 3 which are arranged from bottom to top are arranged in the desulfurizing tower, the spraying structure 2 is connected with external slurry preparation equipment 4, and can also be connected with an auxiliary slurry storage tank communicated with the slurry preparation equipment, the side wall of the desulfurizing tower 1 is also provided with a demister washing structure 5, the demister washing structure 5 faces the demister 3, the demister flushing structure 5 is connected with a water storage structure 6 at the outer side of the desulfurizing tower 1, the bottom of the desulfurizing tower 1 is connected with a gypsum dewatering system 7 through a connecting pipeline, the gypsum dewatering system comprises a water filtering water tank 8, the water filtering water tank 8 is connected with the slurry preparation equipment 4 through a connecting pipeline, the water filtering tank 8 is further connected to a wastewater treatment structure 9, and the wastewater treatment structure 9 is connected to the water storage structure 6. The thick liquid at the bottom of the tower is handled through gypsum dewatering system, and the waste liquid can arrive drainage water tank, and drainage water tank's water can get into the preparation of thick liquid and carry out water cycle and use, and then can influence the preparation speed of thick liquid, and then influence the thick liquid volume that sprays, can realize spraying the control regulation of structure normal water, and the setting up of waste water treatment structure makes the defroster wash the water yield of structure and also can carry out certain control and then guarantee the holistic water balance in the desulfurizing tower.
Further, the bottom of the desulfurizing tower 1 is connected with a second gypsum dewatering system 10 through a connecting pipeline, and the second gypsum dewatering system is also connected with a water filtering tank 8. The slurry discharge amount at the bottom of the desulfurizing tower is increased, and the adjustment and control of water in the tower are facilitated.
Further, an external water pipe 11 is arranged on the water storage structure 6. The wastewater treatment structure is provided with a water discharge pipe 12. Realize external moisturizing and drainage, guarantee the normal work of desulfurizing tower.
Furthermore, a connecting branch pipe 13 is further arranged between the water storage structure and the demister washing structure, and the connecting branch pipe and a connecting pipeline between the connecting branch pipe and the demister washing structure are arranged in an up-and-down position relationship. All be provided with the valve on connecting branch pipe, the connecting tube, realize controlling the defroster and wash the inflow of structure.
The working principle of the utility model is as follows: the thick liquid carries out desulfurization treatment by spraying the structure blowout to the flue gas, the defroster washes structure blowout water and washes the defroster, at the low-load during operation, need reduce the moisturizing volume, can close and connect the branch pipe, the volume of advancing of direct reduction water, and simultaneously, second gypsum dewatering system also carries out the volume of work increase thick liquid, close the connecting tube between drainage water tank and the thick liquid preparation equipment, close the connecting tube between the waste water treatment structure even and the retaining structure, the volume of inpouring of reduction water on the whole, realize the water balance in the holistic desulfurizing tower.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
