Description
(1) technical field:
The present invention relates to Industrial Boiler flue gas desulfurization and dedusting technical field, is the combination high-efficiency wet method sulphur removing and dust removing device that a kind of dry dust removal and wet method sulphur removing and dust removing are combined into one specifically.
(2) background technology:
At present, burning back desulfurization is generally adopted in Industrial Boiler flue gas desulfurization, the desulfurization of burning back divides dry method, do three kinds of wet method and wet methods, what the most generally use in these three kinds of sulfur methods is wet desulphurization, the basic process of wet desulphurization is with desulfurizing agent solution washing flue gas in desulfurization reaction tower, make both that strong chemical reaction and mass transport process take place,, reach the purpose that purifies flue gas to remove the sulfide in the flue gas.
Existing Industrial Boiler wet method sulphur removing and dust removing device can be divided into two big classes, a class split type deduster that to be dedusting separate with desulfurization; Another kind of is the integral type dust-removing desulfurizing device that dedusting and desulfurization combine.
Existing split type wet method sulphur removing and dust removing device has two kinds, and a kind of is that multi-tube dust cleaner adds water-bath expansion chamber doctor treatment, and another kind is that multi-tube dust cleaner adds the spray type desulphurization method.It is that boiler smoke at first enters multi-tube dust cleaner and carries out dry dust removal that multi-tube dust cleaner adds water-bath expansion chamber doctor treatment, flue gas through one-time dedusting is sent into the desulfurization of water-bath expansion chamber by air-introduced machine, flue gas enters chimney behind water bath desulfurization in the water-bath expansion chamber, its shortcoming is that floor space is big, need enough places to arrange expansion chamber, water level control simultaneously is difficult, resistance is too big when water level is high, cause the boiler operation under positive pressure, when water level is low, cause desulfurization invalid, also have desulfurized effect can not reach higher standard; Multi-tube dust cleaner adds the flue gas elder generation process multi-tube dust cleaner that the spray type desulphurization method is a boiler, flue gas after the dedusting enters devulcanizer through flue, flue gas in devulcanizer desulfurization after air-introduced machine enters chimney, its shortcoming is that floor space is big, it is many that multi-tube dust cleaner adds desulfurizer rear pass elbow, the air inducing resistance is big, need to increase air-introduced machine power, to move towards consistent flue gas with water serious because of desulfurization water injector and flue gas, corrosion air-introduced machine and chimney, sticky particles in the flue gas is bonded in the hard attachment of formation on the draught fan impeller, causes the impeller disequilibrium, long-term normal operation that can not be continuous.
Existing integral type dust-removing desulfurizing device is that dedusting and desulfurization are carried out in same container, and desulfurization water and dirt are drained from sewage draining exit simultaneously.Integral type wet method sulphur removing and dust removing device can divide two big classes, one class is common gallet water curtain dust collector, this deduster floor space is bigger, installation period is long, the resistance of deduster own is big, and water entrained by steam causes the air-introduced machine overload, and water consumption is big, and cause secondary pollution easily, the sedimentation basin volume is big and need outfit to drag for mud equipment; Another kind of is the wet method sulphur removing and dust removing device of steel, its shortcoming is that desulfurization water once uses (the also reusable edible that has), waste water and easily cause secondary pollution, the pH value of desulfurization water is difficult to regulate, be interrupted blowdown by artificial, the operational effect fluctuations can not be stablized and reaches desulfurized effect, and smoke evacuation band water, machine and chimney in corrosion is drawn.
The applicant is 02213128.0 in the patent No. of application on March 1st, 2002 in addition, and project name is the patent of combination high-efficiency wet method sulphur removing and dust removing device, and its underpart dry dust removal device is a monotubular, and its rotary separator is easy to wear, needs frequently to change; Also have certain moisture in the flue gas of the wet-desulfurizing dust remover on its top in addition, air-introduced machine and chimney are had corrosion; Also have on its outside sedimentation basin and also will establish dosing compensator device, equipment complexity, cost height.
Thereby a kind of efficiency of dust collection height, desulfurized effect good, do not corrode air-introduced machine and chimney, minimizing flue gas circulating resistance, using water wisely, the secondary pollution of elimination sewer, equipment is simple, cost is low combination high-efficiency wet method sulphur removing and dust removing device was not seen at present.
(3) summary of the invention:
Purpose of the present invention is intended to overcome the deficiency of above-mentioned prior art, and provide a kind of efficiency of dust collection height, desulfurized effect good, do not corrode air-introduced machine and chimney, minimizing flue gas circulating resistance, using water wisely, the secondary pollution of elimination sewer, equipment is simple, cost is low combination high-efficiency wet method sulphur removing and dust removing device.
