Description

Technical Field

[0001] The present application belongs to the technical field of cooling before sampling of various water quality tests for boilers in the metallurgical industry, and specifically relates to a cooling water circulation device for calcining a high-temperature sampling rack. Background Art

[0002] The steam boiler high temperature sampling rack is mainly used for sampling and testing of boiler feed water, boiler boiler water, boiler saturated steam, and boiler superheated steam. Because the temperature of saturated steam, superheated steam, and boiler water is relatively high during sampling, they need to be cooled before sampling and testing.

[0003] The traditional sampling rack cooling method is to use industrial water cooling, which connects the industrial water to the sampling rack cooler and discharges it into the sewage after a period of time. The industrial water quality is relatively hard, and the cooler often scales and clogs, which often leads to pipe bursts, affecting production efficiency and requiring a large amount of maintenance work. In addition, the cooled water is discharged to the sewage plant, resulting in a large amount of industrial water waste. Summary of the invention

[0017] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0018] Before describing in detail the various embodiments of the present application, the technical concept of the present application is first briefly described: currently, when cooling the calcined high-temperature sampling rack, industrial water is usually introduced into the cooler. The industrial water is hard and can easily cause scaling and clogging of the cooler, affecting the service life and production efficiency, while also causing a large amount of industrial water waste. To this end, the present application provides a cooling water circulation device for the calcined high-temperature sampling rack, which connects the desalted water tank with the calcined high-temperature sampling rack through an outlet pipe and a return pipe, uses the desalted water as a cooling medium, and recycles the desalted water after cooling is completed, thereby avoiding scaling inside the calcined high-temperature sampling rack and achieving water conservation. The specific principles of the cooling water circulation device for the calcined high-temperature sampling rack of the present application are described below in conjunction with more embodiments.

[0019] Specifically, Figure 1As shown, the cooling water circulation device for the calcination high-temperature sampling rack of the present embodiment 1 includes a desalted water tank 10, a water outlet pipeline 20 and a water return pipeline 30. The desalted water tank 10 has a water outlet 11 and a water inlet 12. One end of the water outlet pipeline 20 is connected to the water outlet 11 and the other end of the water outlet pipeline 20 is used to connect to the calcination high-temperature sampling rack 40. One end of the water return pipeline 30 is connected to the water inlet 12 and the other end of the water return pipeline 30 is used to connect to the calcination high-temperature sampling rack. Exemplarily, the water outlet 11 is located at the bottom of the desalted water tank 10, and the water inlet 12 is located at the top of the desalted water tank 10. The desalted water in the desalted water tank 10 is transported to the calcination high-temperature sampling rack 40 through the water outlet pipeline 20, and the desalted water is circulated back to the desalted water tank 10 through the water return pipeline 30, so as to realize the recycling of the desalted water.

[0020] In one or more embodiments, the water outlet pipeline 20 includes a water outlet pipe 21, a circulating water pump 22 and a water tank outlet valve 23, and the circulating water pump 22 and the water tank outlet valve 23 are both installed on the water outlet pipe 21. Exemplarily, there are two water tank outlet valves 23, and the two water tank outlet valves 23 are respectively installed at both ends of the circulating water pump 22. On the one hand, the circulating water flow rate can be controlled by adjusting the opening of the water tank outlet valve 23, and on the other hand, two water tank outlet valves 23 are used, and when both are closed at the same time, it is convenient to overhaul the circulating water pump 22.

[0021] In one or more embodiments, the return water pipeline 30 includes a return water pipe 31 and a water tank inlet valve 32, and the water tank inlet valve 32 is installed at the connection between the return water pipe 31 and the desalted water tank 10. The circulating water flow rate can be controlled by adjusting the opening of the water tank inlet valve 32. In addition, when the water tank inlet valve 32 is closed, the pipeline can be inspected and repaired.

[0022] Furthermore, the outlet pipe 20 further includes a first sampling rack valve 24, which is installed on the outlet pipe 21 and close to the inlet of the calcination high temperature sampling rack 40. The return pipe 30 further includes a second sampling rack valve 33, which is installed on the return pipe 31 and close to the outlet of the calcination high temperature sampling rack 40. By adjusting the opening of the first sampling rack valve 24 and the opening of the second sampling rack valve 24, the flow of circulating water entering the calcination high temperature sampling rack 40 is controlled and the cooler 41 of the calcination high temperature sampling rack 40 is conveniently inspected and repaired.

[0023] The working process of the cooling water circulation device is as follows:

[0024] When the cooling water circulation device is installed and connected, all valves will be opened, and the circulating water pump 22 will be started to allow the desalted water to enter the cooler 41 to cool the boiler high-temperature water. Observe the temperature gauge. When the temperature of the cooling water and the sampling water cannot meet the sampling requirements, adjust the opening of each valve to control the flow of the cooling water. When the temperature is adjusted to meet the sampling requirements, the cooling water circulation device can operate continuously. When the circulating water pump, water pipe, and cooler need to be repaired, stop the circulating water pump, close all valves and disassemble them.

[0025] The specific implementation methods of the present application are described in detail above. Although some embodiments have been shown and described, those skilled in the art should understand that these embodiments can be modified and improved without departing from the principles and spirit of the present application whose scope is defined by the claims and their equivalents. These modifications and improvements should also be within the scope of protection of the present application.
