[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the oil removal plant for biological deodorizing filter tank of the present utility model.
[embodiment]
Refer to shown in Figure of description 1, the utility model is a kind of oil removal plant for biological deodorizing filter tank, and it is made up of a few parts such as pretreatment box 1, coalescent deoiling device 2, middle oil-collecting canal 3, air-float degreasing device 4, level control box 5, gas-liquid mixing pump 6, circulated sprinkling pump 7 and shower nozzles 8.
Wherein, described pretreatment box 1 middle and lower part is provided with an exhaust gas entrance 9, and oil-containing foul waste gas is entered treatment unit by it.
Described coalescent deoiling device 2 and air-float degreasing device 4 are contained in pretreatment box 2, and are positioned at below exhaust gas entrance 9, adopt integrated compact form like this, reduce oil-removing area volume.PP modified filler layer is filled with in described coalescent deoiling device 2.
Described middle oil-collecting canal 3 is arranged on the centre of coalescent deoiling device 2, and it is for collecting oil slick.Described middle oil-collecting canal 3 is connected with an oil exit pipe 10, and this oil exit pipe 10 is for discharging oil slick.
Described air-float degreasing device 4 is arranged on the below of middle oil-collecting canal 3, and it is for oil removal by air bubbling.
Described level control box 5 was connected with pretreatment box 1 by a liquid level communicating pipe 11, and it can regulate the liquid level of pretreatment box 1, and adjustable oil slick enters middle oil-collecting canal 3.Described level control box 5 is provided with a liquid level sensor 12, and this liquid level sensor 12 is for showing the liquid level of level control box 5.
Described gas-liquid mixing pump 6 is located between air-float degreasing device 4 and level control box 5.Gas and liquid mixture is delivered to air-float degreasing device 4 by described gas-liquid mixing pump 6..
Described circulated sprinkling pump 7 is arranged on a shower 13, and this shower 13 connects level control box 5 and shower nozzle 8.
The principle of design of the oil removal plant for biological deodorizing filter tank of the present utility model is as follows: the oil content in oily(waste)water is agglomerated into less oil droplet particle through coalescent deoiling device 2; Make little oil droplet limit large through air-float degreasing device 4 again, rise to liquid level, form oil lamella.Oil lamella is coalescent at the water surface, water from below with level control box 5 UNICOM.Gas-liquid mixing pump 6 and circulated sprinkling pump 7 connect level control box 5, and level control box 5 liquid level is equal with main pretreatment box 1 profit district liquid level.During normal operation, run by level control box 5 and carry out Liquid level, now oil float is on pretreatment box 1 liquid level.When oil is abundant time, level control box 5 is intake, and pretreatment box 1 inside liquid level rises with level control box 5 liquid level and rises.When rising to oil extraction liquid level, the inner floating oil slick of pretreatment box 1 enters middle oil-collecting canal 3, discharges pretreatment box 1.
Above embodiment is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
