The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to
Convenient for description, is illustrated only in attached drawing and invent relevant part.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Referring to FIG. 1, the present embodiment provides a kind of gas concentration detection apparatus, including carrier fluid disk 2, on the carrier fluid disk 2
It is placed with seal closure 1, the seal closure 1 is sealed for placing product to be detected between the seal closure 1 and the carrier fluid disk 2
Connection；
The seal closure 1 has at least two through-holes 4, and port lid is detachably provided on each through-hole.
In the present embodiment by will be sealed in carrier fluid disk sealed set, by product to be detected be placed on seal closure carry out
Reaction so that gas is full of inside entire seal closure, by the way that the through-hole being arranged on seal closure is arranged repeatedly to gas therein
It is sampled detection, the gas density that the lead to the hole site being wherein arranged on seal closure can detect as needed determines, gas is close
Spend it is larger through-hole is just opened in seal closure lower end, gas density is smaller to be just opened in seal closure upper end or top by through-hole, real
The accuracy of existing sampled gases.
Further, it is contained with liquid in the carrier fluid disk 2.Carrier fluid disk and seal closure are realized by liquid in the present embodiment
Between sealing, liquid is placed in carrier fluid disk first when in use, seal closure is then placed on sealing achieved above
Effect.
Further, the liquid is oil, and the water content of the oil is less than or equal to 0.3%.It is preferably adopted in the present embodiment
It is sealed with oil, for example, the oil of water content ＜=0.3% such as diesel oil, lubricating oil.
Further, bracket 3 is additionally provided in the seal closure 1, the bracket 3 is for placing product to be detected, the support
3 upper level of frame is higher than the liquid levels.
Bracket in seal closure is used for placing product to be detected, and wherein bracket upper surface is higher than liquid level so that for sealing
Liquid product to be detected will not be had an impact.
Further, 3 center of the bracket is located at the carrier fluid disk center on same vertical line.
Center is preferably placed in 1 placement location center of seal closure with carrier fluid disk 2 in the present embodiment to overlap, the bracket 3
Center is placed with the carrier fluid disk 2 and is overlapped in placement center so that the device use is more stablized, and gas diffusion is relatively uniform.
Further, each logical 4 holes are arranged on point crosspoints such as the N on each side in seal closure top surface, N be more than
2 positive number.
The detection of gas, will preferably lead to after the adjusting and reaction that multiple through-holes progress air pressures are arranged in seal closure top surface
Hole is arranged on point crosspoints such as the N on each side in top surface, and multiple through-holes are uniformly arranged, and sampling is evenly.
The present embodiment also provides ammonia concentration detection method after a kind of hydrolysis of aluminium lime-ash, and this method uses above-mentioned device.
It, can be fast by using above-mentioned apparatus to the detection of progress ammonia concentration after aluminium lime-ash hydrolysis in the present embodiment
