Description
Technical Field
The utility model relates to a desulfurizing tower technical field especially relates to a be applied to high-efficient defogging device of combination formula on desulfurizing tower.
Background
At present, most of flue gas desulfurization in China adopts a wet desulfurization process, and flue gas treated by a desulfurization tower carries a large amount of slurry fog drops, so that subsequent treatment equipment and parts of the desulfurization tower are seriously corroded, and the problem of 'smoke and rain' is seriously harmful to the environment.
Therefore, a demister must be installed at the outlet of the desulfurization tower for demisting the flue gas saturated with water vapor after desulfurization. At present, the tops of most wet desulphurization towers are provided with two stages of baffle plate demisters, and firstly, the demisters are simple in structure, high in capture efficiency for medium-size and large-size fog drops and incapable of capturing fine liquid drops with the particle size smaller than 20 micrometers, so that the phenomenon that desulfurized flue gas carries water seriously is caused. Secondly, the baffle plate demister utilizes the inertia force of liquid drops in the flue gas to impact the plate to separate gas and water, so that the efficiency of capturing the liquid drops by the demister is increased along with the increase of the flow velocity of the flue gas, the flow velocity is high, the inertia acting on the liquid drops is large, the gas-water separation is facilitated, when the flow velocity exceeds a certain limit value, the liquid film on the plate can be peeled off by the flue gas, secondary water carrying is caused, and the demisting efficiency is reduced.
Disclosure of Invention
An object of the utility model is to overcome the not enough of above-mentioned technique, provide a modular high-efficient defogging device, improve original baffling board defroster to the technical problem that droplet entrapment is inefficiency and the secondary takes water.
In order to realize the purpose of the utility model, the utility model adopts the technical scheme that: a combined efficient demisting device is arranged at a top outlet above a spray layer of a desulfurizing tower and is characterized by comprising a baffle plate demister and a tube bundle demister which are arranged at intervals from bottom to top, wherein the baffle plate demister and the tube bundle demister are respectively clamped and fixed up and down through two supporting ring plates; the support ring plates on the lower surface of the tube bundle demister are provided with two layers, and a rectifying grating plate is clamped between the two layers of support ring plates; the outer edge of the supporting ring plate is fixed on the inner wall of the desulfurizing tower, and the inner diameter of the supporting ring plate is slightly smaller than that of the desulfurizing tower; and flushing water pipes which spray upwards are respectively arranged between the tube bundle demister and the baffle plate demister and below the baffle plate demister.
Furthermore, the water outlets of the flushing water pipes between the pipe bundle demister and the baffle plate demister are respectively aligned with the pipe bundles of the pipe bundle demister.
Furthermore, the flushing water pipe is fixed through a water pipe supporting beam with two ends arranged on the inner wall of the desulfurizing tower.
Furthermore, triangular reinforcing ribs are connected between the bottom surfaces of the supporting ring plates on the lower surfaces of the rectification grid plates and the baffle plate demister and the inner wall of the desulfurization tower.
Furthermore, the bottom surfaces of the supporting ring plates on the lower surfaces of the rectification grid plates and the baffle plate demister are respectively provided with a ring plate supporting beam along the diameter direction, and two ends of the ring plate supporting beam are arranged on the inner wall of the desulfurization tower.
The utility model has the advantages that: compared with the existing two-stage baffle plate demister, the pipe bundle demister replaces the upper-stage baffle plate demister, fine liquid drops are captured more efficiently, the demisting effect is better, the required installation space is small, the required washing water amount is small, and the water consumption is saved; compared with a wet electrostatic dust collector, the device has the advantages of low investment, low operating cost and small occupied space when realizing deep dust collection; meanwhile, the device is fixed through the supporting ring plate, the fixing strength is high, the falling is not easy, and the demisting efficiency is not influenced.
