According to above-mentioned purifier, its characteristics are: the thickness of described clarifier waste gas adsorption chamber spacer ring layer is 80 millimeters, and the distance between per two concentric ring of spacer ring layer is 75 millimeters.
Set forth design and the principle of selecting so down emphatically.
The principle of charcoal absorption is: active carbon has certain surface, adsorption capacity is because the residing situation of particle of its surperficial particle and inside and different, attracting each other between the internal particle makes its force balance and offsets, and the attraction of superficial layer is not balanced, so just adsorb more other particle easily, adsorbent surface is long-pending bigger, and adsorption capacity is stronger.Charcoal absorption gas is very capable, is that the porous structure with itself has substantial connection, hole the more, surface area is bigger, adsorption capacity is also stronger.
The number of plies of active carbon layer and bed thickness are essential suitably to be selected.Cause is bled and the resistance of active carbon purifying layer has constituted a pair of contradiction, make clean-up effect quite a lot of, certainly the number of plies of active carbon layer and bed thickness are some more for well, but unsuitable thickening active carbon layer will make resistance increase, and can produce the motionless phenomenon of suction, as select the excessive blower fan of airflow pressure, will bring new noise pollution, therefore, the utility model is selected two layers of active carbon layer for use, every bed thickness is 100～150 millimeters is advisable, and active carbon selects the bar-shaped active carbon of Ф 3 * 4.
The spacer ring layer is designed to concentric ring at a certain distance, axially identical with airflow direction, and be welded with spacer ring curved slab made of plastic between per two concentric rings, why adopt this shape, be because such percent opening greater than the percent opening of on thick plastic plate, opening a plurality of holes, or other formation.Good permeability like this, resistance is little.The intensity height.
Design one eccentric shelves ring mainly is to consider that charcoal absorption moisture content is of long duration between active carbon layer and spacer ring layer, and itself can sink because of weight increases, and the space is caused on top, and waste gas is run away without purifying adsorption layer.Also pay special attention to reduce the local resistance and the on-way resistance of whole system in design, this is so that reduce the loss of blower fan additional energy.Bar seam inlet scoop is near wind regime, be operating as principle with not overslaugh, air channel and elbow iso-curvature radius are big as far as possible, to reduce the pressure loss, because fluid is through elbow, section pipe and joint etc. will produce local resistance, when fluid passes through above-mentioned regional area, to produce dead band or vortex, air-flow does not flow with main flow, constantly turns round and round, form mutual collision and friction between air-flow, consume some energy, moreover owing to flow through section and elbow are right, the size of flow velocity and the direction of air-flow will change sharply, make continuous variation of velocity flow profile rule on each useful area cause that the additional friction on the fluid also can consume some energy, when air-flow flows in pipeline in addition, also will produce resistance because friction takes place for viscosity of self and tube wall, thin more its resistance of pipeline is big more concerning the air-flow of certain flow.
It is according to the characteristics decision of descaling bath that bar seam inlet scoop is adopted in the suspended hood end, because descaling bath is longer, can not influence the operation that workman's pickling picks and places part again, so can only be installed on the side of descaling bath, simultaneously in order to make the air draught effect even on whole descaling bath total length, suspended hood has adopted diverging duct, and bell-mouthed height is decided according to particular location.
For make waste gas in clarifier fully by charcoal absorption, it is longer to make it in clarifier stroke, the time of staying is some more, the air inlet that for this reason designs clarifier is last, exhaust outlet is down.
The clarifier front end leaves sufficient room as the waste gas surge chamber, in case waste gas pours in down a chimney.
Advantage of the present utility model is: equipment is simple, it is extremely convenient to operate, floor space is little, can not cause new pollution in the work, clean-up effect is more stable, the waste gas of various compositions can once be adsorbed, and the gas after the processing can reach the discharge standard of GBJ4-3 regulation, the also renewable less use of active carbon consumption.
