Abstract
The utility model discloses a static box for measuring animal waste greenhouse gas emission rate, which comprises a box body and a base, wherein the box body and the base are of cylindrical shapes, a fan is arranged in the box body, the fan is fixed on a box body top plate through a fan installation rod, and a fan power supply is fixed on the fan installation rod. The box body is of the cylindrical shape, and enables gas in the static box to be more conveniently and uniformly fixed compared with a square, thereby being not easy to produce dead angles. The fan power supply and a temperature recorder are arranged in a built-in portable mode, each static box is completely independent, and is not limited by external condition and stationing distance when sampling. The static box for measuring the animal waste greenhouse gas emission rate is convenient to use, and is high in measurement accuracy rate of gas.
Description
Technical field
The present invention relates to a kind of static chamber of measuring animal wastes greenhouse gas emission speed, be particularly useful for measuring livestock and poultry farm Li Dui middenstead greenhouse gas emission flux.
Background technology
At present, the static chamber of measurement water body and farmland emission flux of gas exists.This type of static chamber major part is square, comprises two parts of casing and base, and temperature measurement probe and the fan power supply of box house are external to outside the case.In addition, the static chamber of measuring the water body emission flux of gas has air bag, be in suspended state with the assurance casing at the water surface, and volume is less.The maximum characteristics of static chamber of measuring the farmland emission flux of gas are that the static chamber height changes along with the change of crop species to be determined.Therefore this type of static chamber is targetedly when using.If with the measurement of this type of static chamber for the animal wastes emission flux of gas, have certain drawback.At first, the gas emissions difference of different material, suitable static chamber volume and size are the bases of accurate measurement gas drainage rate.Secondly, when external circuit, may cause the restriction that box sealing is tight, be subjected to having or not external power supply equipment when sampling.Secondly, the corrosivity of animal wastes is very strong, and needs long-time observation, and therefore, to casing, especially the material requirements of base is than higher.
The utility model content
The purpose of this utility model is to be applied to mismatch problem in the animal wastes greenhouse gas emission flux measurement process for the static chamber that overcomes other kind.A kind of portable static chamber of measuring animal wastes greenhouse gas emission flux that is exclusively used in is provided, and this static chamber can accurately be measured the discharging slope of animal wastes greenhouse gases, and makes simply, and is easy to use, overcome and piled the restriction that the middenstead does not have electric supply installation.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The static chamber of measurement animal wastes greenhouse gas emission speed of the present utility model, comprise casing and base, described casing and base are cylindrical, are provided with fan in casing, fan is fixed on the roof box by the fan mounting rod, and fan power supply is fixed on the fan mounting rod.
The utility model is provided with water sealed tank in the outer rim of base.
The utility model is provided with Portable Automatic humiture registering instrument in casing.
The utility model also is provided with the pressure equilibrium bag in casing, the pressure equilibrium bag is connected with equalizing pipe, and equalizing pipe passes wall box and is exposed to outside the casing.
The utility model also is provided with air collecting pipe at the sidewall of casing.
Adopt the technical solution of the utility model, casing is column type, compares with square, and the mixing of gas in the case of being more convenient for is difficult for producing the dead angle.Fan power supply and moisture recorder are built-in portable, and each static chamber is independent fully, are not subjected to external condition when sampling like this and the restriction of the distance of layouting.The utility model is easy to use, the accuracy rate height of measurement gas.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The static chamber of measurement animal wastes greenhouse gas emission speed of the present utility model comprises casing 1 and base 7 as shown in Figure 1, is provided with water sealed tank 6 in the outer rim of base 7.Described casing and base are cylindrical, are provided with fan 10 in casing, and fan 10 is fixed on the roof box by fan mounting rod 13, and fan power supply 12 is fixed on the fan mounting rod.
Be provided with Portable Automatic humiture registering instrument 8 in casing, Portable Automatic humiture registering instrument 8 is fixed on the wall box by linking up with 9.Be provided with pressure equilibrium bag 2 in casing, pressure equilibrium bag 2 is connected with equalizing pipe 3, and equalizing pipe 2 passes wall box and is exposed to outside the casing, is provided with air collecting pipe 5 at the sidewall of casing, and the air collecting pipe mouth of pipe is provided with medical two-way valve 4.For the ease of carrying, be provided with handle 14 at the casing top.
Specific embodiment of the utility model is as follows:
Top case: the right cylinder that is end sealing, internal diameter is 60cm, 2 mixed gas fans and 1 battery case are housed in the high 50cm(case, fan is apart from sidewall and the equal 20cm in top, at the wall box parallel with fan internal diameter being installed is the stainless steel sampling pipe of 1.5mm, the long 36cm of steel pipe, the length of box house is 30cm, outer length is 6cm.At the sidewall of distance top 10cm internal diameter being installed is the stainless-steel tube of 1.5mm, and length overall is 12cm, is positioned at box house and outside length is 6cm, in connect the long medical plastic balance pipe of 1m.Box inside is apart from 1 stainless steel hook of top 25cm place welding (hanging Portable Automatic humiture registering instrument), 2 handles of outside top welding, the carrying when being convenient to each gas production.
Base is the right cylinder that two ends do not have the end, and internal diameter is 60cm, and high 20cm adds the high water sealed tank of 6cm, water seal groove width 1.5cm.
Sampling time when measuring animal wastes greenhouse gas emission flux is generally 8:00-11:00 in the morning, before each sampling, checks earlier whether accumulator electric-quantity is sufficient in the static chamber, if not enough, earlier accumulator is full of.Open the fan in the casing then, the humiture analyzer is hung on the sidewall of casing, so that record the ambient temperature and humidity in the casing.After the beginning, buckle casing, adding water rapidly seals static chamber in water sealed tank, note correct time, get sample one time every 10min, the gas of gathering is injected the aluminum-plastic composite membrane gas sampling bag of 0.5L fast, and number with marking pen, at the correct time of minute book record sampling, guarantee to extract in half an hour 4 gaseous samples.The sampling while is with rain glass measurement air pressure at that time.The sample of gathering detects the greenhouse gases relative content through chromatography of gases, and demarcates with gas, obtains actual content.Sampling time interval is as transverse axis, and the gas volume concentration ratio is done straight line as the longitudinal axis, and this straight slope is exactly certain gas purging slopes of animal wastes.
According to embodiment, be example (establishing three repeated sampling points) with the Methane Emission speed of measuring beef cattle ight soil, the practical measurement of this static chamber is tested its result such as table 1:
Table 1 static chamber is measured beef cattle ight soil Methane Emission speed result
As can be seen from Table 1, this kind static chamber can be measured the speed of beef cattle ight soil Methane Emission accurately, and its facies relationship number average has reached 0.999 level.
