Abstract

The utility model relates to a sewage treatment pool waste gas measuring device, which comprises a gas collecting cylinder, a gas flow meter, a gas collecting cylinder fixing device and a pressure controller, etc. The utility model solves the problem that waste gas generated by sewage treatment pool can not be measured currently and lays the foundation for treating sewage treatment pool waste gas. The utility model can be effectively used in waste gas measurement of various sewage treatment pools.

Description

Treatment tank flue gas measurement device

The utility model relates to the measurement mechanism that a kind of treatment tank produces waste gas, particularly the gas measurement device of volatilization of large tracts of land liquid surface and fermentation generation.

In industries such as oil recovery, oil refining, chemical industry, leather, printing and dyeing and metallurgy, exist a large amount of sewage-farms, wherein very major part is an open installation, the gas that has a large amount of volatile organic matters, inorganics and biofermentation to produce in sewage disposal process is dispersed in the atmosphere, all produce a large amount of escaping gases as the oil interceptor of refinery, biochemical treatment tank etc. and enter air, working environment and atmosphere are caused severe contamination.

Further perfect along with the enhancing of people's environmental consciousness and environmental regulation can cause that to the processing of these open-air treatment tank volatilization gas people pay close attention to.If will handle the volatilization gas of open-air treatment tank, at first to measure the gas flow that treatment tank produces, also there is not at present reported in literature to measure the device or the instrument of gas flow that treatment tank produces, in fact there are not effective measurement mechanism and method yet, therefore, also can't effectively handle harmful gas that treatment tank produces.

The purpose of this utility model provide a kind of simple in structure, easy to use, measure the measurement mechanism that treatment tank accurately produces waste gas.

The utility model comprises gas surge drum 3, gas meter 1, and gas surge drum 3 communicates with gas meter 1 by conduit.

Fig. 1 is the synoptic diagram of an example of the utility model.

Fig. 2 is the synoptic diagram of another example of the utility model.

Fig. 3 is the synoptic diagram of the 3rd example of the utility model.

Further specify structure of the present utility model and working method below in conjunction with accompanying drawing.

The utility model can also comprise pressure control part 2 and gas surge drum 3 is placed liquid surface or device wherein, be used in combination with fixed support post 6 as buoyancy tube 4, clamper 5, fixed support post 6 or clamper 5.

Gas surge drum 3 of the present utility model can be made the cross section and be circular, square or other suitable shape, its material can be selected metal materials such as organic materials such as PVC or iron plate, be corrosive as institute's contact liq, then should use resistant material or apply anti-corrosion material.Above-mentioned gas meter does not have specific (special) requirements, low pressure, atmosphere gas flowmeter commonly used can use, can measure waste gas produced volume, also can measure its quality, can select for use as required as wet test meter, spinner-type flowmeter, mass flowmeter etc., preferably wet test meter.

In order to measure the exhausted air quantity that treatment tank produces under certain pressure, can before or after the gas meter 1 of the utility model device, pressure controller 2 be set, pressure control can be used the water seal of simple certain altitude, also can be pressure control valve.

The utility model gas surge drum 3 bottoms can fixed buoyancy tube 4 (as Fig. 1), and gas surge drum 3 can be floated in the liquid, and buoyancy tube 4 cross sections can be circular, square or other suitable shape, and its material can be identical with gas surge drum 3, also can be different.Adopt this mode, because gas surge drum 3 can fluctuate with the fluctuation of treatment pond liquid level, therefore measured tolerance is the real gas amount that treatment tank produced.

Gas surge drum 3 of the present utility model also can adopt clamper 5 to fix (as Fig. 2), also can be fixed on (as Fig. 3) in the treatment tank with fixed support post 6, or the method that adopts both to combine fixes.Adopt this mode, because the position of gas surge drum 3 does not change with the treatment tank liquid level variation, therefore measured tolerance comprises that " breathing " that cause owing to liquid fluctuating acts on the tolerance that produces, and in actual applications, this tolerance also is important data.

Treatment tank tolerance measurement mechanism of the present utility model can be applied to various treatment tanks, when using, according to the big or small exhausted air quantity of measuring certain area treatment tank of the sectional area of surge drum 3, can estimate the total air capacity of entire sewage treatment pond then.

Treatment tank measuring device for gas of the present utility model has the following advantages:

1, simple in structure, manufacture, installation, easy to use.

2, applicability is wide, can be used for various treatment tanks.

3, can conveniently obtain the tolerance that treatment tank produces under the different condition.
