Description
Technical field
The utility model relates to double-suction type gas sampling device on a kind of batch quantity hot dipping zinc pond, belongs to the specific equipment field of the waste gas control of top, batch quantity hot dipping zinc pond, discharging collection.
Background technology
In galvanizing was produced, dust-laden exhaust gas such as a large amount of effusion ammonium chlorides of top, zinc pond meeting, zinc chloride, zinc fume and zinc oxide dust were not as being controlled, will pollute the workshop, influence HUMAN HEALTH, as not handled, will be discharged into atmospheric environment from the workshop, atmosphere is polluted.For preventing the diffusion of dust-laden exhaust gas, will dispose exhaust emission system, these dust-laden exhaust gas are collected, handled.
At present a lot of manufacturing enterprises still do not have effective measure of control and specific equipment to top, galvanizing pond waste gas, and part enterprise adopts import equipment, and effect is also desirable not to the utmost.Import equipment mostly adopts the mode of box-shaped seal closure that waste gas is controlled and collected, because galvanizing zinc pond is longer, part reaches more than the 30m, cabinet space is big, the intake-gas amount is corresponding excessive, moreover most of galvanizing production is the intermittent type input and output material, and the box-shaped seal closure must adopt intermittent type folding gate, this just causes vacuum fan power height, dutycycle height, and the exhaust gas emission effect is subjected to very big restriction.It is big to cause equipment to take up an area of, the cost height.
Summary of the invention
In order to solve the deficiency of now zinc-plated industry to existing on the waste gas pollution control and treatment, double-suction type gas sampling device on the batch quantity hot dipping zinc pond is proposed, can realize collection to top, the galvanizing pond waste gas of medium-width.The utility model provides a kind of device that is used for the wide galvanizing of 0.6～1.2m pond top gas sampling, and this device has adopted double-suction type gas sampling mode, the waste gas that produces on the galvanizing pond is concentrated be discharged into emission-control equipment and handle.
Double-suction type gas sampling device on the batch quantity hot dipping zinc pond, comprise the low-noise centrifugal ventilator, variable valve, air-suction duct, air-suction duct is a uniform cross section rectangle air-suction duct, two uniform cross section rectangle air-suction ducts are positioned at the both sides in zinc pond, it has five air suction inlets respectively on the two side in zinc pond, with top, suction zinc pond dust-laden exhaust gas, five air suction inlets are wide, equidistantly, length is from diminishing successively to blower fan direction one end away from low-noise centrifugal ventilator one end, above uniform cross section rectangle air-suction duct, be provided with windsheild, stop that top, air suction inlet clean air sucks uniform cross section rectangle air-suction duct.The waste gas of top, zinc pond is inhaled into uniform cross section rectangle air-suction duct, finally concentrates through the low-noise centrifugal suction fan to be discharged into emission-control equipment.Wind speed, blast by variable valve equal cross section rectangle air-suction duct are regulated.
Double-suction type gas sampling device on the batch quantity hot dipping zinc pond is compared advantage and the positively effect that is had with conventional art
1) upward double-suction type gas sampling device is littler than box-shaped sealing bell-type gas sampling device intake-gas amount, and input and output material need not intermittent type folding gate and destroys the air-flow environment during production, and influences the exhaust gas emission effect.
2) compare with legacy equipment that to have ventilation little, vacuum fan power height, dutycycle are low, save the advantage of energy consumption.
3) air quantity, wind speed can be regulated, the collection of top, galvanizing pond waste gas under suitable different size and the operating mode, and adaptability is good.
4) the equipment occupation of land is little, and consumptive material is few, and operation site is visual strong, does not influence operation.The device activity member is few, and the life-span is long, keeps in repair easy.
