Industrial analysis and sampling equipment

Abstract

The invention relates to industrial analysis and sampling equipment. The industrial analysis and sampling equipment comprises a control valve group and a sample container, the sample container comprises an open-ended container body, the control valve group and the sample container comprise a channel used for sampling and primary flushing / discharge, a needle-type stop valve group is arranged on the channel of the control valve group and the channel of the sample container, an inlet end positioned at an upstream side of the needle-type stop valve group and an outlet end positioned at a downstream side of the needle-type stop valve group are arranged on each channel; an outlet end of the channel used for sampling and an inlet end of the channel used for primary flushing / discharge of the sample container are communicated to an opening of the container body; an outlet end of the channel used for sampling of the control valve group and an inlet end of the channel used for sampling of the sample container are communicated, and an outlet end of the channel used for primary flushing / discharge of the sample container and an inlet end of the channel used for primary flushing / discharge of the control valve group are communicated. During a sampling process, repeated dismounting of the sample container is not required, and cleaning for the equipment is not influenced.

Description

technical field [0001] The invention relates to the technical field of industrial analysis, in particular to industrial analysis sampling equipment. Background technique [0002] Industrial analysis is the application of analytical chemistry in industrial production, which can guide and promote production. Each industrial production unit generally has a quality inspection center or a central laboratory, especially in petrochemical, coal chemical, pharmaceutical, and water treatment industries, which involve many industrial analysis items. And according to production needs, the analysis frequency of each analysis item is different. In the early stage of device start-up or when the device is running unstable, the analysis frequency of some analysis items will be very high. [0003] The premise of industrial analysis is to sample the substance to be analyzed. Current industrial analysis and sampling equipment generally includes a sampler, a control valve, a sample container,...

AI Technical Summary

Problems solved by technology

[0016] 1. Step 2 flushes the conduit and steps 4, 5, 6, and 7 flush the sample container. The flushed sampling / sampling medium is discharged on the spot. If the discharge is flammable, toxic and harmful, it will pollute the environment, and there is a risk of fire and explosion accidents. Hidden dangers, more importantly, it is easy to cause acute or chronic poisoning by inhalation of sampling / sampling personnel

[0017] 2. The sampling / sampling operation process is complicated, and there is a potential for unqualified flushing caused by human factors, resulting in deviation or error in the analysis results

[0018] 3. Under the condition of high temperature and high pressure, the probability of the above problems will increase

[0019] 4. The sampling / sampling process is complicated and the work efficiency is low

[0020] 5. The sampling equipment cannot be fully assembled at the initial stage, and the conduit between the sampling valve 1 and the control valve 2 must be flushed before assembling the sample container 3

The reason for this is that the control valve 2 is a single valve with only a single inlet and outlet, once fully assembled, there is no extra outlet for the flush connection line to exit
