Description

Technical Field

[0001] The present application relates to a boiler water cooling sampling technology, and in particular to a boiler water sampling cooler. Background Art

[0002] The boiler water sampling cooler is a device used to cool the boiler water and steam water in the boiler for sampling for testing. The boiler water and steam in the boiler are usually at a high temperature and cannot be directly sampled and measured, so they need to be cooled before sampling.

[0003] After the existing boiler water sampling cooler takes samples, some boiler water will remain in the pipe. The next time you take samples, you need to drain it for a while before taking samples. However, even if the existing boiler water sampling cooler discharges the boiler water remaining in the pipe from the last time, during the discharge process, the boiler water remaining in the pipe will be mixed with the subsequent boiler water, affecting the test results. In addition, the discharge process before sampling takes a long time, which will also delay the efficiency of sampling and testing. Utility Model Content

[0004] The present application provides a boiler water sampling cooler, which is used to solve the problem that boiler water remains in the pipeline after sampling by the existing boiler water sampling cooler, affecting the next detection.

[0005] The present application provides a boiler water sampling cooler, comprising a cylinder, wherein the upper end of the cylinder is connected to a cooling water inlet pipe, and the lower end is connected to a cooling water discharge pipe. A spiral boiler water cooling pipe is arranged in the cylinder, and a water inlet at one end thereof passes through the cylinder from the upper end and is connected to a boiler, and the other end is a protruding sampling port. The lowest point of the lower end of the boiler water cooling pipe is connected to a drain pipe, and a drain valve is installed on the drain pipe. An air inlet is arranged at the upper end of the water inlet, and an air inlet valve is installed on the air inlet. A stop valve is installed on the pipe connecting the water inlet and the boiler.

[0006] Optionally, the water inlet is connected to one end of a tee, and the other two ends of the tee are connected to the boiler through a water inlet pipe and a return pipe respectively. The stop valve is installed on the pipe of the connecting section between the tee and the water inlet, and a one-way valve is installed on the return pipe.

[0007] Optionally, a partition is transversely fixed in the cylinder body to separate the cylinder into two chambers, the boiler water cooling pipe is located in the chamber at the upper end of the partition, the drain pipe extends vertically downward into the chamber at the lower end of the partition, the chambers at the upper and lower ends are connected by a drain pipe, the cooling water inlet pipe is located in the upper chamber, and the cooling water drain pipe is located in the lower chamber.

[0008] Optionally, a temperature monitor for checking the temperature is installed on the sampling port.

[0009] Optionally, a liquid level window is provided on the side wall of the cylinder.

[0010] Compared with the prior art, the beneficial effects of the boiler water sampling cooler provided by the present application are:

[0011] After sampling is completed, the remaining water in the boiler water cooling pipe can be discharged through the drain pipe, so that the boiler water cooling pipe remains empty and the test results are not affected by the mixing of the previous water when sampling again. Discharging the remaining water in the pipeline can effectively shorten the sampling time during the test and improve the efficiency of sampling and testing. The air inlet is used to intake air during venting to ensure that the water in the boiler water cooling pipe can be quickly emptied. After venting, close the air inlet valve.

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0020] like Figure 1-Figure 4 As shown, an embodiment of the present application provides a boiler water sampling cooler, including a cylinder 1, the upper end of the cylinder 1 is connected to a cooling water inlet pipe 2, and the lower end is connected to a cooling water discharge pipe 3, a spiral boiler water cooling pipe 4 is provided in the cylinder 1, a water inlet 5 at one end thereof passes through the cylinder 1 from the upper end and is connected to the boiler, and the other end is a protruding sampling port 6, the lowest point of the lower end of the boiler water cooling pipe 4 is connected to a drain pipe 7, a drain valve 8 is installed on the drain pipe 7, an air inlet 9 is provided at the upper end of the water inlet 5, an air inlet valve 10 is installed on the air inlet 9, and a stop valve 12 is installed on the pipe connecting the water inlet 5 and the boiler.

[0021] When in use, cooling water for heat exchange is introduced into the cylinder 1 through the cooling water inlet pipe 2, and the cooling water after heat exchange is discharged through the cooling water discharge pipe 3. The water inlet 5 is connected with the boiler through a pipeline, and the boiler water in the boiler can flow from the water inlet 5 into the boiler water cooling pipe 4 in the cylinder 1, and is cooled in the process of passing through the boiler water cooling pipe 4, and finally flows out from the sampling port 6 for sampling.

[0022] After the sampling is completed, the stop valve 12 is closed to cut off the outflow of the boiler water. Then the drain valve 8 and the air inlet valve 10 are opened to discharge the remaining boiler water in the boiler water cooling pipe 4 from the drain pipe 7 to drain the boiler water cooling pipe 4. The air inlet 9 is used to intake air into the boiler water cooling pipe 4 when draining water to balance the atmospheric pressure.

[0023] In this embodiment, after sampling is completed, the remaining boiler water in the boiler water cooling pipe 4 can be discharged through the emptying pipe 7, so that the boiler water cooling pipe 4 remains empty, and the boiler water from the previous time is not mixed into the next sampling to affect the detection result. The air inlet 9 is used to take in air during emptying, ensuring that the boiler water in the boiler water cooling pipe 4 can be quickly emptied, and the air inlet valve 10 is closed after emptying.

[0024] In a possible implementation, the water inlet 5 is connected to one end of the tee pipe 11, and the other two ends of the tee pipe 11 are connected to the boiler through the water inlet pipe 13 and the return pipe 14 respectively. The stop valve 12 is installed on the pipe of the connecting section between the tee pipe 11 and the water inlet 5, and a one-way valve 15 is installed on the return pipe 14.

[0025] After sampling is completed, closing the stop valve 12 can cut off the outflow of boiler water. The boiler water entering the water inlet pipe 13 can flow back to the boiler through the return pipe 14, so that the boiler water entering the water inlet pipe 13 can circulate continuously, and the boiler water in the water inlet pipe 13 can maintain dynamic flow. The boiler water in the water inlet pipe 13 is kept consistent with the boiler water in the boiler, avoiding residual non-flowing dead water in the water inlet pipe 13, and improving the accuracy of sampling. The one-way valve 15 is used to make the boiler water in the water inlet pipe 13 flow in one direction.

[0026] In one possible implementation, a partition 16 for dividing the cylinder 1 into two chambers is fixed transversely in the cylinder 1, the boiler water cooling pipe 4 is located in the chamber at the upper end of the partition 16, the drain pipe 7 extends vertically downward into the chamber at the lower end of the partition 16, the chambers at the upper and lower ends are connected by a drain pipe 17, the cooling water inlet pipe 2 is located in the upper chamber, and the cooling water drain pipe 3 is located in the lower chamber.

[0027] The lower chamber is used to collect the boiler water for sampling discharged from the drain pipe 7 and mix it with cooling water through the drain pipe 17. The mixed boiler water and cooling water can be used for heat exchange again after cooling, avoiding waste caused by direct discharge of sampling water.

[0028] In a possible implementation, a temperature monitor 18 for checking the temperature is installed on the sampling port 6 .

[0029] It is used to check the temperature of the outlet water sample during sampling, and the outlet water temperature can be controlled by adjusting the outlet water speed through the control valve.

[0030] In a possible implementation, a liquid level window 19 is provided on the side wall of the cylinder 1 .

[0031] The liquid level in the cylinder 1 and the drainage condition of the drain pipe 7 can be easily checked through the liquid level window 19 .

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
