Description
Technical field
The utility model relates to catalysis filed of flue gas purification in petrochemical industry, specifically a kind of entrance guiding flue of catalysis fume desulfurizing tower.
Background technology
Be attended by a large amount of catalyst fines in general industry enterprise catalysis flue gas, concentration reaches 50 ~ 150mg/m 3, and catalysis flue-gas temperature is at 70 DEG C ~ 190 DEG C, and this just causes catalysis flue gas to have the feature of high-sulfur, high dust, difficult operation.Research shows, in flue gas, the suspension of less than 100 μm can enter human body, sticks on bronchus and lung, is detrimental to health; SO2 and NOX in flue gas, entering air can cause acid rain, and make agriculture, woods, animal husbandry impaired, industrial equipment, building, historical place etc. are corroded.In order to protect the environment of surrounding, country puts into effect " petroleum refining industry pollutant emission standard ", requires that the enterprise being provided with catalytic unit is necessary to build a set of smoke eliminator, specifically comprises denitration, desulfurization, dedusting three parts.
Circular pipe is adopted to enter desulfurizing tower in traditional desulfurizing tower air inlet, because the treatment quantity of catalytic unit is larger, such as disposal ability at the catalytic unit treatment quantity nominal situation of 100-140t/h greatly about 200000Nm3/h(wet basis), therefore the diameter of circular flue consideration is comparatively large, and in making, cost is larger.And conventional flue is entering desulfurizing tower according to straight up and down formula, distributor is easily producing resistance, affect air inlet effect, pressure drop increase, thus reduces smoke desulfurization efficiency.
Utility model content
The purpose of this utility model is exactly the defect existed for prior art, provides the catalysis fume desulfurizing tower inlet distributor that a kind of structure is simple, easy to operate, water conservancy diversion is effective, flue gas resistance is little.
The concrete technical scheme of the utility model is: comprise flue, flue gas air deflector and spray equipment, described flue by first section, stage casing and latter end three sections of cross sections are that the flue of rectangle bends successively and is formed by connecting, and the elbow of adjacent two sections of flues is provided with flue gas air deflector, described latter end flue is provided with spray equipment.
Described first section of air flue horizontal is arranged, described stage casing flue be connected with first section of flue backward upper right side extend and and angle between first section of flue be greater than 90 degree, extend to the right after described latter end flue is connected with stage casing flue and and angle between the flue of stage casing be not more than 90 degree.
Angle between described stage casing flue and first section of flue is 105 degree, and the angle between described latter end flue and stage casing flue is 90 degree.
Described first section of flue, stage casing flue are respectively equipped with expansion joint.
Described spray equipment, for being arranged in juxtaposition two cover spray equipments, is respectively circulating slurry sprinkling device and fresh water spray equipment, and often cover spray equipment forms by pipeline, valve and spray head.
Described flue gas air deflector for form by organizing V-type deflector more, and the angle between the angle of described V-type deflector and adjacent two sections of flues is consistent.
The bottom surface of described latter end flue is provided with spring support.
The utility model flue gas water conservancy diversion is effective, and easy to make, the assurance device long cycle of operation, and continuous gas entry and receipts oil, substantially increase gas cleaning efficiency.

Fig. 2 is the structural representation of V-type deflector;
In figure: 1-first paragraph rectangular flue, 2-first expansion joint, 3-first built-in flue gas air deflector, 4-second segment rectangular flue, 5-second expansion joint, the built-in flue gas air deflector of 6-second, 7-flange, 8-the 3rd section of rectangular flue, 9-spring support, 10-desulfurizing tower, 11-loop slurry pipeline, 12-loop slurry valve, 13-loop slurry shower nozzle, 14-fresh water pipeline, 15-fresh water valve, 16-fresh water shower nozzle, 17-smoke discharge tube line, 18-V type deflector.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1, a kind of catalysis fume desulfurizing tower inlet distributor, comprises the built-in flue gas air deflector 3 of flue entrance first paragraph rectangular flue 1, first expansion joint 1, first, the built-in flue gas air deflector 6 of second segment rectangular flue 4, second expansion joint 5, second, flange 7, the 3rd section of rectangular flue 8, spring support 9, desulfurizing tower 10, loop slurry pipeline 11, loop slurry valve 12, loop slurry shower nozzle 13, fresh water pipeline 14, fresh water valve 15, fresh water shower nozzle 16, smoke discharge tube line 17 etc.
The concrete technical scheme of the utility model is: catalysis flue gas (temperature is at 70 DEG C ~ 190 DEG C) is through smoke inlet pipeline, successively through first paragraph rectangular flue 1, first expansion joint 2, arrive the first built-in flue gas air deflector 3, change direction is carried out at this, enter into second segment rectangular flue 4, again through the second expansion joint 5, to the second built-in flue gas air deflector 6, change direction is carried out at this, the 3rd section of rectangular flue 8 is entered into through flange 7, flue gas finally enters desulfurizing tower 9, carry out desulfurizing and purifying, final flue gas is discharged into air by discharge pipe 17 after desulfurizing tower carries out desulfurizing and purifying, rectangular flue is supported by spring support 9, prevents distortion.
