Detailed description of the invention
Below in conjunction with drawings and Examples, technical characterictic and advantage with other that the utility model is above-mentioned are doneMore detailed description.
As shown in Fig. 1-6, a kind of air seal set of realizing pollution sources sealing under complex working condition of the utility model,Described air seal set comprises by the square of suspender belt or support fixed installation (can adjust fixed angle) uselessGas fume trap cover 1, it is made with the thick galvanized steel plain sheet of 1.2mm, and waste gas fume trap cover 1 middle part is provided with waste gas fume trap cover mouth2, (before connecting waste gas treatment equipment, also can waste gas be assisted by blower fan for being communicated with waste gas treatment equipmentSuck waste gas treatment equipment), waste gas fume trap cover 1 surrounding is equipped with the high strength fibre of an employing fire-proof and damp-proofThe balance pipe 3 that material is made, balance pipe 3 is by suspender belt 11 and withhold 10 steel that are installed on default pipe-lineOn cable 8,4 balance pipe head and the tail are communicated with by PVC elbow, balance pipe 4 one end openings that head and the tail are communicated with, oneEnd is by 7 shutoff of blast cap plug, and described balance pipe transverse bottom is provided with and all presses air port 4, i.e. a seam is all pressedThe openend of pipe 3 is connected with blower fan 6.
Waste gas fume trap cover mouth be located at exhaust emission source directly over, cover mouthful covers the exhaust emissions faces of pollution sources, ensuresThe waste gas rising all can enter in cover mouth, and balance pipe is the pressure-equalizing passageway that is centered around waste gas fume trap cover mouth edge, all pressesFour edges of pipe edge cover mouth are laid, and totally four sections, one section, the edge of each cover mouth. The laying of balance pipe can be horizontalTo, also can be longitudinally or at an angle, determine according to the concrete operating mode at scene, principle is the gas ejectingStream can seal the waste gas that pollution sources distribute completely, facilitates waste gas fume trap cover mouth to collect, and balance pipe has air inlet (to enterGas port is located at one end of balance pipe, and the other end of balance pipe is installed shutoff sealing.
The installation of balance pipe:
Balance pipe can adopt any suitable and form field working conditions to install, and adopts the peace of hanging in the present embodimentDress form:
When installation, first install on route and draw 2 parallel wireropes at anticipation pipeline, wirerope employing diameter 4mm's is plasticGalvanized steel cable is anti-skidding anticorrosion, and the horizontal range of two wireropes is suitable with balance pipe diameter. Wirerope length is according to actual workCondition is determined, except two ends are fixing, does a level at interval of 5 meters (determine according to operating mode, stabilize to principle)Support fixed support, after wirerope is fixing, level, firm, the level height of wirerope is as the criterion with actual condition.
Suspender belt and withholding is set in balance pipe both sides, is stuck on wirerope, adjacent two to withhold spacing be 600mm. (rootAdjustable according to operating mode)
Inflate (all pressure ventilation pipe in the time not inflating, after not full state, inflation, present cylindrical, when workBlower fan source of the gas is constantly inflated, ensure to keep in equal pressure ventilation pipe barotropic state, for all pressing air port that certain speed is providedAir-flow, waste gas fume trap cover mouth, with equal pressure ventilation pipe cooperating, realizes sealing place of the pollution sources under complex working conditionReason, top-draught hood mouth adopts galvanized steel plain sheet to make, and adopts lifting to install), the gas pressure that enters balance pipe can be graduallyRaise and form gases at high pressure, gases at high pressure form air-flow wall by all pressing air port to penetrate, and complete the sealing to pollution sources.Between each balance pipe section, can be communicated with, can be also disconnected, uses an air inlet when connection, pointWhile opening, each disconnected part all needs an air inlet. ), the total length of pipeline and the outward flange length phase of covering mouthWhen. The caliber (if square-section can be converted into the circular arc interface of homalographic) of balance pipe is larger, to inflateTime static pressure to be far longer than dynamic pressure be principle, in this case, dynamic pressure is negligible. Balance pipe can adoptWind-distributing pipe makes, also can adopt galvanized steel plain sheet to make.
All press air port to be out hole or the seam in balance pipe bottom, the flow of the quantity of hole or seam and size and balance pipe,Area is relevant with the speed of sealing gland stream:
SHole＝KQPipeSPipe/VHole
Wherein:
SHoleIt is the area of hole or seam;
K is adjustment factor;
QPipeIt is the total flow of balance pipe;
SPipeIt is the sectional area of balance pipe;
VHoleIt is the flow velocity of the sealing gland stream of hole or seam;
Case: the total flow of balance pipe is 12000m3The sectional area of/h, balance pipe be 0.5 square metre (balance pipeDiameter is 800mm), require that all to press the flow velocity in air port be 10 metre per second (m/s)s, all press the reference area in air port to be12000X0.5/ (10X3600)=0.1667 (square metre). Owing to there is Air Leakage, need to apply adjusting,Generally removing to adjust coefficient is 0.8, and the area of all pressing air port is 0.8X0.1667 square metre=0.1333 square metre.All press air port if arrange 100 at balance pipe, the area in each air port is 0.001333 square metre, eachThe diameter in air port is 4.12mm.
Configure by science, between sealing gland region and external environment, form air-flow enclosing wall, inside and outside this road air-flow wall is incited somebody to actionInterference in air flow separate, but the transmission of workpiece and personnel's turnover are unaffected.
The appearance of sealing gland cover mouth has been created superior to the efficient trapping of waste gas of pollutant for realizing under complex working conditionPart.
Above-described embodiment is described preferred embodiment of the present utility model, not to this practicalityNovel scope limits, and is not departing under the prerequisite of the utility model design spirit ordinary skill peopleVarious distortion and improvement that member makes the technical solution of the utility model, all should fall into the utility model claimIn the definite protection domain of book.
