Description
Technical field
What the present invention relates to is the emission-control equipment of a kind of pickling or electroplating device, belongs to technical field of waste gas treatment.
Background technology
In cables manufacturing enterprise, need many wire acid cleanings of make versus buy and electroplating device, to can process wire rod before cables manufacturing.Because adopting, pickling or electroplating device pile acid solution in pickling or plating tank; at least the in the situation that of energising; acid solution conventionally can be evaporated and be formed acid mist gas, so often distributing one stink at pickling or the plating scene of wire rod, shows that air has been subject to very serious pollution.In order to solve the air pollution problems inherent of this acid mist, some cable processing enterprises have taked some measures, comprise pickling or electroplating device are made to closed, as configured closing cap etc. on the cell body of pickling or plating tank; But need only the production normally, these acid solutions will inevitably leak in environment around by variety of way, form atmospheric pollution.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of special and wire acid cleaning or electroplating device matching used, rational in infrastructure, easy to use and reliable, can effectively process the pickling of acid waste gas processing or the emission-control equipment of electroplating device.
The object of the invention is to complete by following technical solution, the emission-control equipment of described pickling or electroplating device, it mainly comprises a spray tower for waste gas, the top of tower body is provided with the air outlet that connects the delivery pipe of giving vent to anger, on the lower sides of tower body, offer inlet mouth, and on inlet mouth, be circumscribed with inlet pipe and be connected in a ventilating fan, the inlet mouth of ventilating fan is connected on pickling or electroplating device by a long adapter; In described tower body, according to being furnished with up and down two groups of spray equipments, these two groups of spray equipments are connected in a water tank that can add alkali lye by an external extension tube attached and spray pump; The bottom of described tower body is provided with water leg, and described water leg connects the sewage lagoon of peripheral hardware.
Described spray equipment mainly comprises inside loop and outside loop pipe, evenly offers the mouth spray of downward spray alkali lye or the spray header of multiple downward spray alkali lye is evenly installed on endless tube on endless tube; The inner side, air outlet that described tower body top is offered, faces air outlet and is provided with a ring baffle, and at least three contiguous blocks that this ring baffle arranges by periphery are connected on the wall of tower body limit, and form gas channel between ring baffle and tower body limit wall.
Described spray equipment also comprises a flow deflector that is arranged on inside and outside endless tube below, and above flow deflector, offers uniform water conservancy diversion air drain and water conservancy diversion water hole; The periphery of described ring baffle is provided with the dash swash plate of oblique lower layout.
The invention belongs to the one improvement to prior art, to can be specially adapted for the off gas treatment of wire acid cleaning or electroplating device, have rational in infrastructurely, easy to use and reliable, can effectively process acid waste gas processing, meet environmental requirement, the feature such as energy-saving and cost-reducing.
Brief description of the drawings
Fig. 1 is one-piece construction schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, the emission-control equipment of pickling of the present invention or electroplating device, it mainly comprises a spray tower for waste gas, the top of tower body 1 is provided with the air outlet 3 that connects the delivery pipe 2 of giving vent to anger, on the lower sides of tower body 1, offer inlet mouth, and on inlet mouth, be circumscribed with inlet pipe 4 and be connected in a ventilating fan 5, the inlet mouth of ventilating fan 5 is connected on pickling or electroplating device by a long adapter 6; In described tower body 1, according to being furnished with up and down two groups of spray equipments 7, these two groups of spray equipments 7 are connected in a water tank 10 that can add alkali lye by an external extension tube attached 8 and spray pump 9; The bottom of described tower body 1 is provided with water leg 11, and described water leg 11 connects the sewage lagoon 12 of peripheral hardware.
Shown in figure, described spray equipment 7 mainly comprises inside loop and outside loop pipe 13, evenly offers the mouth spray of downward spray alkali lye or the spray header 14 of multiple downward spray alkali lye is evenly installed on endless tube on endless tube 13; 3 inner sides, air outlet that described tower body 1 top is offered, face air outlet and be provided with a ring baffle 15, at least three contiguous blocks 16 that this ring baffle 15 arranges by periphery are connected on the wall of tower body limit, and forming gas channel 17 between ring baffle 15 and tower body 1 limit wall, this structure setting can be reduced aqueous vapor along with air-flow is taken tower body 1 out of from air outlet 3; Described adapter 6 can and be connected to many pipe taps 18, and every pipe tap connects many pickling and electroplating device by the suction hood 19 of end, and it can carry out off gas treatment by the acid mist gas centralized collection of many pickling and electroplating device generation in separate unit tower body 1.
Another further implementation of the present invention is: also comprise a flow deflector 20 being arranged on below inside and outside endless tube 13 at described spray equipment 7, and flow deflector 20 offers uniform water conservancy diversion air drain 21 and water conservancy diversion water hole 22 above, the setting of this structure, can increase the mutual ac contactor of aqueous vapor, thereby the acid in acid mist gas is increased to the probability contacting with alkali lye, reach better acid mist treatment effect; The periphery of described ring baffle 15 is provided with the dash swash plate 23 of oblique lower layout, due to this dash swash plate 23 being set, has increased the effect of dash.
