[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings.

[0023] Combine Figure 1 A sampling device for uniformly collecting compounds in industrial waste gas includes a cart 1 and a sampling box 2 arranged above the cart 1. A sampling tube 3 and a sampling head 4 are provided on the upper surface of the sampling box 2. An adjustment component 5 for increasing the uniformity of sampling is provided at the bottom of the sampling box 2. A collection component 6 for facilitating the collection of sampled gas is provided on one side of the sampling box 2.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1:

[0026] See also Figures 1-4 The collection component 6 includes connecting square tubes 61 arranged on both sides of the sampling box 2, and mounting blocks 62 arranged on the inner walls of each group of connecting square tubes 61. An activated carbon filter plate 63 is arranged between each group of connecting square tubes 61 and the sampling box 2. The outer surface of each group of mounting blocks 62 is threadedly connected to a sample box 64 through a bolt 65. Each group of sample boxes 64 and the inner wall of the connecting square tube 61 are provided with an electric telescopic baffle 66. The inner wall of the sample box 64 is provided with a pressure sensor 67, which improves the representativeness of the sampling and the accuracy of subsequent analysis, while ensuring the purity of the sample.

[0027] Each set of sample boxes 64 and the inner wall of the connecting square tube 61 are provided with a sealing ring 7, and one end of the electric telescopic baffle 66 is movably connected to the inside of the sealing ring 7, which increases the sealing of the sample box 64 and the sampling box 2, not only effectively preventing gas leakage, but also ensuring the integrity and safety of sample collection.

[0028] An annular ventilation pipe 41 is provided on the inner wall of the sampling head 4, a connecting pipe 42 is provided on the outer surface of the annular ventilation pipe 41, a hot air blower 43 is provided at one end of the connecting pipe 42, and the bottom of the hot air blower 43 is fixedly connected to the upper surface of the cart 1. The warm air generated by the hot air blower 43 blows toward the sampling head 4, thereby preventing the condensation phenomenon occurring during the exhaust gas sampling process from affecting the sampling results.

[0029] The inner wall of the sampling head 4 is provided with a primary filter 44 to provide preliminary filtration for the sampled gas.

[0030] The inner wall of the sampling box 2 is provided with a condensation plate 21 and a high-efficiency filter 22. The condensation plate 21 removes moisture from the gas, and the high-efficiency filter 22 can improve the purity of the sample.

[0031] The adjustment component 5 includes a square groove 51 opened on the upper surface of the cart 1, a rotating shaft A52 rotatably connected to the inner wall of the square groove 51, and a motor 53 arranged on the inner wall of the square groove 51. The output end of the motor 53 is fixedly installed with a rotating shaft B54. The outer surfaces of the rotating shaft A52 and the rotating shaft B54 are both sleeved with gears 55. The outer surface of the rotating shaft A52 is sleeved with a disc 56. The disc 56 is located above the gear 55. A hydraulic cylinder 57 is fixedly installed on the upper surface of the disc 56. A hydraulic rod 58 is provided at the upper end of the hydraulic cylinder 57. The upper end of the hydraulic rod 58 is fixedly connected to the bottom of the sampling box 2 to adjust the position of the sampling head 4, thereby improving the flexibility and uniformity of sampling.

[0032] A control panel 8 is provided on the outer surface of the sampling box 2. The electric telescopic baffle 66, pressure sensor 67, hot air blower 43, condensing plate 21, motor 53 and hydraulic cylinder 57 are all connected to the control panel 8 by signal and are controlled in a coordinated manner through the control panel 8.

[0033] Specifically, the sampling box 2, sampling tube 3 and sampling head 4 are installed, and then the rotating shaft A52, motor 53, rotating shaft B54 and gear 55 are installed in the square groove 51 in the cart 1, and then the disc 56 is installed to the upper end of the rotating shaft A52, and the hydraulic cylinder 57 and hydraulic rod 58 are installed to the upper surface of the disc 56. Finally, the bottom of the sampling box 2 is fixedly connected to the upper end of the hydraulic rod 58, so that the sampling head 4 can be driven to move up and down and rotate, thereby improving the flexibility and uniformity of sampling. Because the inner wall of the sampling head 4 is provided with an annular ventilation pipe 41, the annular ventilation pipe 41 is connected to the hot air blower 43 through the connecting pipe 42, so that the temperature of the sampling head 4 can be increased, and the condensation phenomenon occurring during the exhaust gas sampling process can be avoided. The sampling result is affected. In addition, the inner wall of the sampling head 4 is provided with a primary filter 44, and the inner wall of the sampling box 2 is provided with a condensation plate 21 and a high-efficiency filter 22. This can not only preliminarily treat impurities in the sampled exhaust gas, but also remove moisture in the high-temperature exhaust gas. Because connecting square tubes 61 are provided on both sides of the sampling box 2, and an activated carbon filter plate 63 is connected between the two, the sample purity can be further improved. Because the two groups of sample boxes 64 are respectively threadedly connected to the mounting block 62 on the inner wall of the connecting square tube 61 by bolts 65, it is convenient to install and disassemble the sample box 64, which not only improves the sample collection efficiency, but also improves the detection accuracy. The opening and closing can be controlled by the electric telescopic baffle 66 to avoid gas leakage during disassembly, and combined with the sealing ring 7, the sealing performance is further improved. In addition, because a pressure sensor 67 is provided in the sample box 64, when the sample in the sample box 64 is full, the operator is reminded to replace the sample box 64 in time to avoid excessive collection affecting the subsequent analysis results, thereby ensuring the accuracy of the data and the continuity of the experiment.
