Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a high-temperature chlorination reaction sampler. Background Art

[0002] Chlorination reactions often involve high temperatures and extreme hazardous situations where the reaction system is filled with chlorine. In fine chemical industry, most kettle chlorination reactions are mainly carried out in a kettle type. Chlorine is introduced into the reaction kettle while heating simultaneously. To determine the reaction end point, it is necessary to take samples from the kettle. Usually, the sampling methods include hanging samples above the kettle or sampling from the bottom of the kettle, etc.

[0003] However, sampling from the upper part of the kettle body often results in a large amount of leakage of chlorine and organic volatiles. Moreover, there are risks of combustion and explosion as well as scalding during the sampling process. At the same time, during the sampling process, it is often necessary to stop introducing chlorine and use negative pressure to pump the chlorine in the kettle to the absorption system, which may affect production efficiency.

[0027] Referring to Figures 1 - 4 , a high-temperature chlorination reaction sampler includes:

[0028] Installation pipe 1;

[0029] The pressure pipe 6 is fixedly connected to the installation pipe 1, and the pressure pipe 6 communicates with the installation pipe 1;

[0030] The sampling pipe 4 is connected in the installation pipe 1;

[0031] The check ball 7 is connected in the installation pipe 1, and the check ball 7 is located directly below the sampling pipe 4;

[0032] The connecting pipe 5 is fixedly connected to the sampling pipe 4;

[0033] The sample outlet pipe 502 is fixedly connected to the connecting pipe 5.

[0034] A rolling plate 101 is fixedly connected to the bottom of the installation pipe 1.

[0035] The rolling plate 101 is an arc-shaped plate.

[0036] Refer to Figure 3 , a sampling port 102 is opened at the bottom of the installation pipe 1, the check ball 7 is located directly above the sampling port 102, and blocks the sampling port 102.

[0037] Refer to Figure 4 , through the arc-shaped rolling plate 101 provided at the bottom of the installation pipe 1, the check ball 7 can slide down quickly to block the sampling port 102.

[0038] A connecting flange 2 is fixedly connected to the installation pipe 1, and the sampling pipe 4 is fixedly connected to the connecting flange 2.

[0039] Refer to Figure 1 , Figure 3 , through the provided connecting flange 2, it is convenient to install the sampler on the reaction kettle body;

[0040] It should be noted that when installing the sampler on the reaction kettle body, the installation pipe 1 is inserted 0.7 m into the liquid level in the kettle body, and the liquid level is 0.4 m higher than the bottom end of the sampling pipe 4.
