[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide a device for automatic steam water delivery and a method of use, so as to solve the problems existing in the above-mentioned prior art, with a simple structure, easy use, and the ability to effectively separate condensed water in steam.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] The present invention provides a device for automatic steam water delivery, such as Figure 1As shown, it comprises: a cylinder 1, a steam inlet pipe 2, a steam outlet pipe 3, a water body 4 and a drainage member. A steam inlet is arranged on the side wall of the cylinder 1, and a steam outlet is arranged on the top of the cylinder 1. The cylinder 1 is used to be detachably fixedly connected to the top of the manhole cover; one end of the steam inlet pipe 2 is connected to the steam pipeline, and the other end is connected to the steam inlet and communicated so as to input steam mixed with condensed water into the cylinder 1; one end of the steam outlet pipe 3 is connected to the steam pipeline, and the other end is connected to the steam outlet and communicated so as to transport the steam separated from the condensed water back to the steam pipeline; the water body 4 is used to be placed in the cylinder 1 to communicate with the steam entering the cylinder The steam mixed with condensed water in the cylinder 1 contacts and then absorbs the condensed water of the steam mixed with condensed water; the top of the drainage piece is connected to the cylinder 1, and the bottom of the drainage piece is connected to the sewer below the manhole cover to discharge the water body 4 in the cylinder 1 that exceeds the preset water level. This structural design allows the steam mixed with condensed water to enter the cylinder 1, and realize the adsorption and separation of condensed water by contacting with the water body 4, and then the steam separated from the condensed water is transported back to the steam pipeline, forming an effective steam automatic water delivery and recycling cycle, improving the utilization efficiency of steam and ensuring the stable operation of the steam system. The cylinder 1 can be detachably fixedly connected to the top of the manhole cover, which is convenient for regular inspection, maintenance and replacement of parts of the device. The device can be maintained without complicated construction operations, reducing maintenance costs and improving maintenance efficiency. The steam inlet is set on the side wall of the cylinder 1, and the steam outlet is set on the top of the cylinder 1. This layout is conducive to the natural flow of steam in the cylinder 1 and the separation of steam and water, and uses gravity to make the condensed water settle faster in the water body 4, thereby improving the separation effect.

[0027] In a preferred embodiment, the device for automatic steam water delivery also includes a first flow valve, which is arranged on the steam inlet pipe 2, and can flexibly adjust the steam input according to the actual production requirements and the operating state of the device. This helps to ensure that the device can operate stably under different working conditions, avoid excessive pressure in the cylinder 1 or poor steam-water separation due to excessive steam flow, and also prevent the inability to meet production requirements due to too small steam flow.

[0028] In a preferred embodiment, the drainage member is an overflow pipe 5, a first drainage hole 6 is provided at the bottom of the cylinder 1, the overflow pipe 5 is provided in the cylinder 1, and the bottom of the overflow pipe 5 is connected and communicated with the first drainage hole 6, the top opening of the overflow pipe 5 is flush with the preset water level of the cylinder 1, and a second drainage hole is provided at the position of the manhole cover corresponding to the first drainage hole 6, and the setting of the overflow pipe 5 enables the water level in the cylinder 1 to be automatically controlled at a preset level. When the water level reaches the preset water level, the water will flow into the manhole through the overflow pipe 5 through the first drainage hole 6 and the second drainage hole, preventing excessive water accumulation in the cylinder 1 from affecting the steam-water separation effect or causing device failure, and ensuring that the device can operate stably and continuously. The drainage method using the overflow pipe 5 has a simple structure and is easy to implement and maintain. Compared with complex mechanical drainage devices, it reduces the number of failure points, improves the reliability of the device, and reduces the maintenance cost and difficulty of repair.

[0029] In a preferred embodiment, the diameter of the first drainage hole 6 is smaller than the diameter of the second drainage hole. A reasonable aperture difference can optimize the smoothness of drainage. The larger diameter of the second drainage hole can provide a smoother drainage path, accelerate the discharge of excess water 4 in the cylinder 1, and help the device to return to a normal water level state more quickly, thereby improving the overall operating efficiency of the device.

[0030] In a preferred embodiment, the overflow pipe 5 is a curved pipe, and the top opening of the curved pipe faces away from the steam inlet. The top opening of the curved pipe faces away from the steam inlet, which can reduce the interference of the steam entering the steam inlet on the drainage of the overflow pipe 5. Because the steam entering the steam inlet may form a local steam flow field, if the overflow pipe 5 opens toward the steam inlet, the steam may directly impact the top opening of the overflow pipe 5, hindering the drainage and even causing the steam to enter the overflow pipe 5, while the orientation away from the steam inlet can effectively avoid this situation, ensure smooth drainage, and effectively reduce steam escape.

[0031] In a preferred embodiment, the overflow pipe 5 is made of a stamped elbow with a diameter of 10 cm and a thickness of 0.8 cm, and the stamped elbow is welded to the first drain hole 6. The use of a stamped elbow with a specific diameter and thickness to make the overflow pipe 5 can ensure that the overflow pipe 5 has sufficient strength and toughness, and will not be easily deformed or damaged under the long-term water pressure and water flow scouring in the cylinder 1. This helps to maintain the normal drainage function of the overflow pipe 5 and extend the service life of the device. The welding connection method can form a good sealing effect between the overflow pipe 5 and the first drain hole 6 to prevent water leakage at the connection. It avoids the situation where the water level in the cylinder 1 is unstable due to leakage, which affects the normal operation of the device, and ensures the operational stability and reliability of the device.

[0032] In a preferred embodiment, the device for automatic steam water delivery also includes a connecting flange 7 and a plurality of connecting bolts 8. The connecting flange 7 is fixedly connected to the outer edge of the bottom of the cylinder 1. The connecting flange 7 is connected to the manhole cover through each connecting bolt 8. The setting of the connecting flange 7 and the connecting bolt 8 provides a stable and reliable connection between the cylinder 1 and the manhole cover. This connection structure can withstand various forces generated during the operation of the device, such as steam pressure, water flow impact force, etc., to ensure that the cylinder 1 is firmly fixed above the manhole cover and will not be easily displaced or shaken, thereby ensuring the safe and stable operation of the device; in addition, the use of the connecting flange 7 and the connecting bolt 8 makes the disassembly and assembly between the cylinder 1 and the manhole cover convenient and quick. When the device needs to be inspected, repaired or parts are replaced, the connecting bolt 8 can be easily loosened to remove the cylinder 1. The operation is simple and efficient, which improves the convenience of device maintenance.

[0033] In a preferred embodiment, the side wall of the cylinder 1 is made of a seamless pipe with a diameter of 60 cm, a wall thickness of 0.6 cm, and a length of 120 cm. The top plate and the bottom plate of the cylinder 1 are made of 0.6 cm thick steel plates, which can provide enough space inside the device to accommodate steam and water 4 for steam-water separation operations, while ensuring that the cylinder 1 has sufficient strength and rigidity. It can withstand the steam pressure inside the cylinder 1 and the external environmental pressure, prevent the cylinder 1 from deformation, rupture, etc., and ensure the safe and reliable operation of the device. The material and structure of the seamless pipe and the steel plate can ensure that the cylinder 1 has good sealing, reduce the possibility of steam leakage, and improve the energy efficiency of the device. At the same time, this material and structure have good durability during long-term use, can resist the influence of factors such as corrosion from steam, water and the external environment, and extend the overall service life of the device.

[0034] In a preferred embodiment, the steam outlet pipe 3 is made of a seamless steel pipe with a thickness of 0.6 cm, a length of more than 100 cm, and a diameter of 5 cm. The steam inlet pipe 2 is made of a seamless steel pipe with a thickness of 0.6 cm and a length of more than 5 cm. The steam outlet pipe 3 and the steam inlet pipe are made of seamless steel pipes consistent with the diameter of the steam pipe. The appropriate thickness can ensure that the steam outlet pipe 3 and the steam inlet pipe 2 will not break or deform under the steam pressure, ensuring that the steam can be safely and stably transported. The sufficient length of the steam outlet pipe 3 can meet the connection requirements between the device and the steam pipe, and the reasonable pipe diameter ensures that the flow rate and flow of the steam meet the operation requirements of the device, ensuring that the steam can be smoothly transported back to the steam pipe after separation, effectively ensuring steam transmission.

[0035] The present invention also provides a method for using the device for automatic steam water delivery as described above, characterized in that it comprises the following steps:

[0036] 1. Device installation and preparation

[0037] 1.1 Site selection and layout: According to the actual distribution of the steam pipe network, select a suitable location above the manhole cover to install the device, ensuring that there is enough space around the device and will not affect the connection and layout of the steam inlet pipe 2 and the steam outlet pipe 3 with the existing steam pipeline.

[0038] 1.2 Installation and connection: First fix the connection flange 7 to the outer edge of the bottom of the cylinder 1, and then use multiple connection bolts 8 to tightly connect the connection flange 7 to the manhole cover, so that the cylinder 1 is firmly installed above the manhole cover. According to the design requirements, one end of the steam inlet pipe 2 is accurately connected to the steam pipeline, and the other end is connected to the steam inlet on the side wall of the cylinder 1 and ensures sealing. Similarly, one end of the steam outlet pipe 3 is connected to the steam pipeline, and the other end is connected to the steam outlet at the top of the cylinder 1 and sealed well.

[0039] 1.3 Inspection and preparation: Before the device is put into use, carefully check whether all the connection parts are firm and loose; check whether the welding place between the overflow pipe 5 and the first drainage hole 6 at the bottom of the cylinder 1 is well sealed and whether there are any leaks; at the same time, check whether the first flow valve on the steam inlet pipe 2 can work normally and whether its opening degree is in a suitable state. In addition, inject an appropriate amount of water 4 into the cylinder 1 to reach the water level required for normal operation.

[0040] 2. Operation phase

[0041] 2.1 Flow regulation and steam input: According to the actual production demand and steam consumption, the flow of steam mixed with condensed water is accurately adjusted through the first flow valve, and the valve is opened to allow the steam to flow into the cylinder 1 through the steam inlet pipe 2. The steam entering the cylinder 1 is further separated from the water body 4 during the contact process with the water body 4, and the condensed water in the steam is adsorbed by the water body 4.

[0042] 2.2 Steam-water separation and steam output: After the adsorption and separation effect of the water body 4, the relatively pure steam from which the condensed water is separated rises in the cylinder 1, enters the steam outlet pipe 3 through the steam outlet at the top of the cylinder 1, and is then transported back to the steam pipeline to re-participate in the recycling of the steam system.

[0043] 2.3 Drainage operation and water level control: During the operation of the device, as steam continues to enter, the water level in the cylinder 1 may rise. When the water level in the cylinder 1 reaches the preset water level, the water will flow through the overflow pipe 5 in the cylinder 1, through the first drainage hole 6 at the bottom of the cylinder 1, and then through the second drainage hole on the manhole cover into the sewer, realizing the automatic drainage function, ensuring that the water level in the cylinder 1 is always within a reasonable range, thereby ensuring the stable operation of the device.

[0044] 3. Maintenance and care stage

[0045] 3.1 Regular inspection: Carry out a comprehensive inspection of the entire device regularly. Check whether there is steam or water leakage at the connection parts of each pipeline. If there is leakage, tighten the connection parts or replace the sealing parts in time; check whether the parameter setting of the first flow valve matches the actual operation situation, and whether the opening and closing flexibility of the valve is normal; check whether the overflow pipe 5 is blocked. If there is any debris blocking it, clean it in time.

[0046] Component maintenance and replacement: Components are maintained as planned based on the device's usage and material characteristics. For example, gaskets, seals and other consumable parts at the connection parts are replaced according to the specified service cycle. For components such as the cylinder 1, steam inlet pipe 2, steam outlet pipe 3 and overflow pipe 5, if wear and corrosion occur, they should be repaired or replaced in a timely manner according to the degree of damage to ensure device performance and work safety.

[0047] Water quality monitoring and treatment: Regularly monitor the water quality of the water body 4 in the cylinder 1. If water quality problems are found to affect the steam-water separation effect, the water body 4 can be treated or replaced. This helps maintain good steam-water separation performance of the device and improves the overall operating efficiency of the steam automatic water delivery device.

[0048] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
