Embodiment Construction

[0036] As mentioned in the background, prior art sampling devices are difficult to clean.

[0037] figure 1 It is a sampling device, and the sampling device includes: a drainage tube 10; a first valve F1 and a second valve F2, located between the two ports of the drainage tube 10; a sampling plug M, located between the first valve F2 and the second valve F3 In the drainage tube 10 between.

[0038] The test tube 20 is part of the device for producing chemical samples, and the test tube 20 has a P1 port and a P2 port; a third valve F3 is arranged in the test tube 20 . The two ports of the drainage tube 10 communicate with the two ports of the test tube 20 respectively. The third valve F3 is disposed between two ports of the test tube 20 . The test tube 20 and the sampling device are integrally formed. The chemical sample is titanium tetrachloride.

[0039] When titanium tetrachloride is produced, titanium tetrachloride enters through port P1 and flows out from port P2 thro...

Abstract

The invention relates to a sampling apparatus and a sampling method. The sampling apparatus comprises: a first draining pipe, wherein the first draining pipe is provided with a first port, a second port and a middle port positioned between the first port and the second port, and the first port is used for introducing a sample to be extracted; a second draining pipe, wherein the second draining pipe is provided with a third port and a fourth port, wherein the third port is communicated to the middle port; a collection device connected to the fourth port; and a protection gas device connected tothe second port and used for introducing a protection gas into the second port. According to the present invention, the sampling apparatus is easy to clean after the operation.

Description

technical field [0001] The invention relates to the production field of chemical materials, in particular to a sampling device and a sampling method. Background technique [0002] In the production process of some chemical materials that are prone to violent reactions with air, in order to analyze the production process of each process and control the process parameters, it is necessary to sample the chemical materials in the production process. [0003] For example, in the process of producing titanium tetrachloride, it is necessary to sample titanium tetrachloride. [0004] At present, the titanium tetrachloride sampling device and the device for producing titanium tetrachloride are integrally formed. The titanium tetrachloride sampling device includes a drainage tube, a sampling valve and a sampling plug. When sampling, titanium tetrachloride in the production process flows through the drainage tube, sampling valve and sampling plug, and the titanium tetrachloride is ex...
