Description
Technical Field
[0001] The utility model relates to a steam pipeline disposal device, belonging to the technical field of steam power devices. Background Art
[0002] A steam pipeline is a kind of heat pipeline and a commonly used heat energy transportation device in industrial production. During the process of transporting steam, the pipeline dissipates heat to the outside, and the steam will condense into water. The condensed water forms water droplets on the inner wall of the pipeline. Due to the action of gravity, the accumulated water will flow to the low point of the pipeline. With the continuous accumulation of condensed water, the steam will carry the condensed water and impact pipeline accessories such as downstream valves, tees, elbows, etc., causing pipeline vibration, and then causing situations such as weld cracking and pipeline falling. Seriously, it may lead to pipeline rupture or even explosion. This situation is very dangerous, may cause casualties and property losses. The steam leaks from the damaged pipeline, may scald nearby personnel, and cause production shutdown and great waste of energy. Therefore, the drainage of steam pipelines is particularly important. At present, it is more common to install a quick-discharge valve at the low point of the steam pipeline to discharge the condensed water in the pipeline. Since the discharged condensed water has a high temperature, it is generally directly discharged to the ground or discharged into a cooling pond, and then discharged into the pipeline after natural cooling. However, this method has a poor drainage effect and will generate a large amount of steam, which is not conducive to environmental protection. If a cooling pond is used to cool and dispose of the externally discharged steam condensate, the cooling pond covers a large area, requires a large investment, and there is a safety risk of personnel falling. Therefore, it is necessary to design a steam pipeline disposal device that can safely and efficiently cool and dispose of the condensed water in the steam pipeline and discharge it safely. Summary of the Utility Model

Detailed Description of the Invention
[0015] The following is a further description of the present utility model through examples in conjunction with the accompanying drawings.
[0016] As shown in the attached drawings, a steam pipeline disposal device includes an input end, an output end, and a disposal device 10. The disposal device 10 is a tank body, with legs 6 provided on the side wall, an inspection hole 16 provided on the top, and a valve III 7 and a pipeline III 8 for sewage discharge provided at the bottom end. The input end includes a valve II 4, a pipeline II 5, and a valve V 15. One end of the pipeline II 5 is connected and assembled at the lowest point of the steam pipeline 1, and the other end is connected and assembled with the lower side wall of the tank body of the disposal device 10. The valve II 4 and the valve V 15 are connected and assembled on the pipeline II 5. The valve II 4 is a steam trap, and the valve V 15 is a control valve. The output end includes a pipeline IV 11. One end of the pipeline IV 11 is connected and assembled on the upper side wall of the tank body of the disposal device 10, and the other end is connected to a sewage well 14. A pipeline I 3 is connected and assembled on the pipeline II 5, and a valve I 2 is connected and assembled on the pipeline I 3. The pipeline I 3 is arranged between the connection of the pipeline II 5 and the steam pipeline 1 and the valve V 15. The lower side wall of the tank body of the disposal device 10 is connected and assembled with a pipeline V 13, and the other end of the pipeline V 13 is connected to a cooling water source. A valve IV 12 is connected and assembled on the pipeline V 13. A spoiler 9 is assembled and fixed on the inner wall of the tank body of the disposal device 10. The spoiler 9 is a plate-like structure, and the outer end is inclined downward towards the inside of the tank body. There are 3 spoilers 9, which are arranged crosswise. The downward inclination angle of the spoiler 9 is 60°, and the lower end of the tank body of the disposal device 10 is conical.
[0017] The pipeline II 5 is installed at the lowest point of the steam pipeline 1, and a valve V 15 and a valve II 4 are installed on it. When there is condensate in the pipeline, the valve II 4 automatically opens and closes automatically after the condensate is discharged. The condensate enters the device through the bottom of the disposal device 10. The external cooling water is connected to the other end of the bottom of the disposal device 10 through the pipeline V 13. The valve IV 12 is used to control the flow rate of the cooling water. The cold water and the hot water are fully mixed and cooled after passing through the spoiler 9, and then are discharged into the sewage well 14 through the pipeline IV 11. An inspection hole 16 is provided at the top of the disposal device 10 for facilitating inspection of the internal situation of the device. A pipeline III 8 is provided at the bottom to discharge the dirt inside the disposal device 10. The valve V 15 is usually in a closed state and is opened when sewage discharge is required.
[0018] In this embodiment, referring to the attached Figure 1-2 , 3 spoilers 9 are welded inside the disposal device 10, and the included angle with the outer wall of the disposal device 10 is 60° obliquely downward. The condensate in the pipeline II 5 enters from the end far from the spoiler 9, and the cooling water enters from the end close to the spoiler 9. The cooling water drives the condensate to flow upward from the bottom of the disposal device 10. During this process, it passes through 3 spoilers 9, is fully mixed and cooled, and then is discharged from the drain port. The flow rate of the cooling water can be controlled by the valve IV 12 to achieve the best cooling effect.
[0019] The bottom of the disposal device 10 is conical. After sundries are deposited, they are discharged through pipeline III 8. Four legs 6 are provided at the bottom to leave an installation space for pipeline III 8. A cushion block is welded to the bottom of the legs to increase the contact area with the foundation, thereby ensuring the stability of the disposal device 10.
[0020] The usage method of the present utility model is as follows:
[0021] After the steam pipeline is installed, pipeline II 5 is connected to the lowest point of the pipeline. The disposal device 10 is installed on the foundation, and pipeline IV 11 is introduced into the sewage well. Valve I 2 remains closed. When maintenance is required or emergency drainage is needed in case of emergencies, it is manually opened by the operator. Valve V 15 remains fully open, and valve III 7 remains normally closed. Next, the disposal device 10 is debugged. After the steam pipeline 1 is ventilated and operated, valve IV 12 is adjusted by the size of the condensate flow in the steam pipeline so that there is no jitter or abnormal noise in the disposal device 10, the water discharged from the drain port has no hot air, and the minimum opening of valve IV 12 is the best state. It should be noted that affected by the external environmental temperature, the output of condensate in the steam pipeline will also be affected. Therefore, it is necessary to adjust the opening of valve IV 12 in a timely manner according to the change of seasons to ensure the normal operation of the disposal device 10 while saving the consumption of cooling water. The disposal device 10 is regularly drained. First, valve V 15 is closed to prevent hot condensate from entering the device, then valve III 7 is opened for drainage. After the impurities are discharged, valve III 7 is closed and valve V 15 is opened to resume the normal operation of the disposal device 10.
[0022] The device of the present utility model has a simple structure, ingenious design, small investment, less land occupation, safety and stability, and strong practicability. It can ensure the drainage of the steam pipeline while avoiding the adverse impact of the overflow of hot air in the cooling pond on the environment. By setting the spoiler, the condensate and cooling water can be fully mixed evenly, realizing the rapid cooling of the condensate in the tank body of the disposal device. The bottom of the disposal device is conical, which is convenient for the impurities in the device to deposit at the bottom, facilitating the separation and collection of pollutants. It solves the problems of high cost consumption and large floor area of the construction cooling pond, and at the same time avoids the potential safety hazards of the cooling pond. The precipitated, purified and cooled condensate is safely discharged through the pipeline. It greatly improves the drainage efficiency and safety of the steam pipeline.
