Abstract
一种新型的湿法脱硫除尘器,涉及湿法脱硫或除尘等废气净化设备,它的结构特点是,风管内设有符合工艺要求的2个以上、并联、固接为一体的文丘里管,每个文丘里管的喉部均设有与进水管连接的喷水孔。使本实用新型的净化效率得到提高，降低了阻力损失,仅为现有锅炉烟气湿法除尘器的2/3,而且在阻力和效力不变的情况下,风管内小直径文丘里管(3)越多,则处理含尘空气的风量越大。
A new type of wet desulfurization and dust collector, which involves wet desulfurization or dust removal and other waste gas purification equipment. Its structural feature is that there are more than two Venturi tubes that meet the process requirements, are connected in parallel and are fixed as a whole. , the throat of each Venturi tube is provided with a spray hole connected to the water inlet pipe. The purification efficiency of the utility model is improved, and the resistance loss is reduced, which is only 2/3 of that of the existing boiler flue gas wet dust collector, and under the condition of constant resistance and effectiveness, the small-diameter Venturi tube ( 3) The more the number, the greater the air volume for handling dusty air.
Description
The utility model relates to off-gas cleaning equipment, further relates to waste gas wet desulphurization or cleaner.
As everyone knows, the wet desulphurization venturi scrubber all is made up of the Venturi tube of establishing in the airduct of cyclone separator top.Because throat's contraction structure of Venturi tube, when making dusty gas pass through throat, the liquid that sprays in the hole for water spraying that is provided with the trunnion place, contact with water, water droplet is atomized by the high speed dust-contained airflow, grit surface air film is broken through by water and becomes moistening, thereby makes grit quicken coalescence in the collision mutually, helps the solid separation in cyclone separator of gas-liquid.Air communication is crossed the throat of contraction simultaneously, because inertial collision makes the mixing that obtains fullest between gas and the liquid.So utilize the principle of Venturi tube to catch grit or absorb various chemical compositions in the gas, sulphur for example, ammonia is most effective in the wet method gas purifying equipment up to now, tests the capturing ability that shows 1 nanometer dust factually and can reach 97%.And equipment volume is little, is the cleaning equipment that generally adopts.
But gas is about 3000-7000Pa even higher by the pressure drop that Venturi tube produces.If the increase throat diameter, then unfavorable drop atomizing reduces collision, holds back and the coalescence effect, if the lengthening throat length, resistance was bigger when efficient was enhanced.
The purpose of this utility model is: provide a kind of efficiency of dust collection height, the wet method sulphur removing and dust removing device that resistance is little.
In order to achieve the above object, the utility model is realized by following scheme.Deduster comprises the precipitation pond of cyclone separator bottom, Venturi tube and water inlet pipe in the airduct of cyclone separator top.Its design feature is, is provided with the Venturi tube that meets more than 2 of technological requirement, parallel connection, fixes as one in the airduct, and the throat of each Venturi tube is equipped with the sparge pipe that is connected with water inlet pipe.
The utility model has the advantages that:
1. owing to adopted the combination in parallel of a plurality of Venturi tubes, make deduster of the present utility model improve purification efficiency, reduced drag losses, only be 2/3 of existing boiler smoke hydrofilter.
2. when the gas flow of processed dust-laden sulfur-bearing was bigger, its efficiency of dust collection and resistance were constant substantially.
Accompanying drawing is an embodiment of the present utility model
The structural representation of Fig. 1 for composing in parallel by 6 Venturi tubes in the utility model
Fig. 2 is the vertical view of 6 Venturi tube parallel-connection structures of the present utility model
In conjunction with the accompanying drawings the utility model is further described
Please mix and read Fig. 1 and Fig. 2, the utility model is made up of precipitation pond (1), cyclone separator (2), Venturi tube (3), water inlet pipe (4), hole for water spraying (5), airduct (6).There are precipitation pond (1), its top to have to be provided with in airduct (6), the airduct (6) 6 parallel connections meeting technological requirement the bottom of cyclone separator (2), and the close wall for the Venturi tube of one (3) and airduct (6) of the affixed weldering in two ends also welds close.
We adopt and handle air quantity is 3000m
3The testing equipment of/h will have the utility model of 6 Venturi tubes (3) to compare with existing hydrofilter in this airduct (6), drag losses has only 2/3.And experiment shows, at resistance with render a service under the constant situation, the minor diameter Venturi tube of the present utility model (3) of composition is many more, and the air quantity of then handling dust laden air is big more.
