Description
Technical Field
[0001] The utility model relates to the technical field of boiler condensate recycling, and specifically relates to a steam boiler condensate recycling and filtering device. Background Technique
[0002] At present, a steam boiler is a device that uses a heat engine or a power station to generate electricity and useful heat simultaneously. The steam boiler has a very large water consumption and extremely high requirements for the water quality in water treatment. Its quality is close to pure water. If most of the condensate can be recycled, it will produce huge economic and environmental benefits. The condensate recovery system recovers the high-temperature condensate discharged from the steam system, which can maximize the utilization of the heat of the condensate, save water, and save fuel.
[0003] The application number is CN202020709091.7, which discloses a steam boiler condensate recycling and filtering device in the field of steam boiler condensate recycling. It includes a filter pipe. The filter pipe includes a circular pipe and two groups of reduced-diameter pipes. One end of the inner cavity of the circular pipe is fixed with a first circular ring plate. The center of the end of the first circular ring plate is provided with a first ring groove. A first connecting ring is installed inside the first ring groove. A filter screen is arranged on the inner wall of the first connecting ring. A solid block is embedded in the center of the filter screen. The end of the first connecting ring is evenly provided with first adsorption magnetic columns around the circumference. The center of the end of the solid block is fixed with a first auxiliary rod. The other end of the inner cavity of the circular pipe is fixed with a second circular ring plate. The center of the end of the second circular ring plate is provided with a second ring groove. A second connecting ring is installed inside the second ring groove. The inner wall of the second connecting ring is fixed with a mounting plate. Water passing ports are arranged around the circumference of the side surface of the mounting plate. The center of the side surface of the mounting plate is fixed with a second auxiliary rod. The second adsorption magnetic columns are arranged around the water passing ports on the other side surface of the mounting plate.
[0004] This structure does not mention the disassembly method of components such as the filter screen and the mounting plate. When the filter screen is blocked by impurities and needs to be cleaned or replaced, and when there is impurity accumulation at the mounting plate and needs to be cleaned, it is difficult to operate. Long-term use will cause the filtration efficiency to continuously decline, affecting the normal operation of the device. Moreover, this structure only focuses on the filtration link and does not involve the collection of condensate after filtration, and it is impossible to centrally manage and store the filtered condensate, making it difficult to ensure that the steam boiler can stably obtain a sufficient amount of recycled condensate when needed.

[0009] The valve control components can also be disassembled and repaired or replaced separately to ensure the long-term stable operation of the entire device. The existence of the valve control components can flexibly control the flow of condensed water. When it is necessary to stop supplying water to the water storage container, such as when maintaining or inspecting the water storage container, the valve can be closed to avoid inconvenience caused by the outflow of condensed water. By connecting the threaded plug to the water storage container, the condensed water that has been initially filtered can be collected and stored for subsequent reuse in the steam boiler system, thereby improving the utilization rate of water resources.
[0010] Furthermore, a threaded connecting pipe is threadedly connected to the inner wall of the top end of the valve control component, and the threaded connecting pipe is in communication with the connecting threaded insert through the valve control component.
[0011] The purpose of this arrangement is that during the use of the device, after the condensed water flows out of the filter, it first enters the threaded connecting pipe, then passes through the internal channel of the valve control component, and flows into the water storage container through the connecting threaded insert, thereby further guiding the water flow path.
[0012] Furthermore, the filter comprises a sealing shell, a drain plug pipe is threadedly connected to the inner wall of the bottom end of the sealing shell, and the top end of the threaded connection pipe is threadedly connected to the bottom inner wall of the drain plug pipe.

[0014] Furthermore, a filter element is fixedly installed inside the sealed housing, a top cover is inserted on the inner walls around the top of the sealed housing, and a sealing ring is fixedly sleeved on the outer wall of the overlapping part of the sealed housing and the top cover.
[0015] The purpose of such a setting is that during the use of the device, the incoming condensed water is guided to the bottom of the filter element through the diversion pipe, passes through the filter element from bottom to top for filtration, and impurities are removed.
[0016] Furthermore, flow pipes are respectively opened on both sides of the top cover, pressure gauges are installed on the inner walls of the top of the top cover and the flow pipes, and threaded grooves are clamped on the inner walls of the outer ends of the flow pipes.
[0017] The purpose of such a setting is that during the use of the device, condensed water enters the filter through the flow pipes, and the pressure gauges installed on the flow pipes monitor the internal pressure of the filter in real time. If the pressure rises abnormally, it may indicate problems such as blockage of the filter element, which is convenient for timely maintenance.
[0018] Furthermore, a diversion pipe is fixedly inserted into the inner wall of the middle part of the bottom end of the top cover, and the bottom end of the diversion pipe extends downward into the bottom hole groove of the filter element.
[0019] The purpose of such a setting is that during the use of the device, after the condensed water enters the top cover, it is guided to the bottom hole groove of the filter element through the diversion pipe, so that the condensed water has a more uniform flow path in the filter element, improves the filtering effect, and ensures that impurities can be fully intercepted.
[0020] The utility model has the following beneficial effects:
[0021] (1) Through the settings of the water storage container, threaded insertion pipe and valve control component, the detachable components are installed at the tail end of the filter. Among them, components such as the valve control component, the connected threaded insertion pipe, the sealing cover, and the water storage container are all detachable. When the water storage container needs to be cleaned or replaced, it can be conveniently disassembled for operation without affecting the normal operation of the main part of the filter. The valve control component can also be disassembled separately for maintenance or replacement, ensuring the long-term stable operation of the entire device.
[0022] (2) Through the provision of a pressure gauge and a diversion pipe, the condensate enters the filter from the flow pipe. The pressure gauge installed on the flow pipe monitors the internal pressure of the filter in real time. If the pressure rises abnormally, it may indicate problems such as a clogged filter element, facilitating timely maintenance. After the condensate enters the top cover, it is guided to the bottom hole groove of the filter element through the diversion pipe, enabling the condensate to have a more uniform flow path within the filter element, improving the filtration effect, and ensuring that impurities can be fully intercepted.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.
[0032] See also Figures 1 - 4 As shown, the utility model is a steam boiler condensate recycling filtering device, including a filter 1 and a detachable component 2, the detachable component 2 is installed at the tail end of the filter 1, the detachable component 2 includes a valve control component 203, the upper and lower inner walls of the valve control component 203 are respectively provided with threaded grooves, the bottom end of the valve control component 203 is threadedly connected with a connecting threaded insert 204, the bottom end of the connecting threaded insert 204 is fixedly sleeved with a sealing cover 205, the top end of the sealing cover 205 is connected to the bottom end of the valve control component 203, the inner wall of the sealing cover 205 is threadedly connected with a water storage container 206, and the valve control component 203 is in communication with the cavity of the water storage container 206 through the connecting threaded insert 204.
[0033] The purpose of such arrangement is that during the use of the device, the condensed water of the steam boiler first enters the filter 1 for preliminary filtration. After being processed by the filter, the condensed water reaches the detachable component 2. The valve control component 203 can control the on-off of the condensed water through its switch state. When the valve is opened, the condensed water passes through the valve control component 203 and flows into the water storage container 206 through the connecting threaded insert 204 for storage so as to be reused. The detachable component 2 is installed at the tail end of the filter, wherein the valve control component 203 and the connected connecting threaded insert 204, the sealing cover 205, the water storage container 206 and other components can be detached. When the water storage container 206 needs When cleaning or replacing, it can be easily disassembled for operation without affecting the normal operation of the filter body; the valve control component 203 can also be disassembled and repaired or replaced separately to ensure the long-term stable operation of the entire device. The existence of the valve control component 203 can flexibly control the flow of condensed water. When it is necessary to stop supplying water to the water storage container 206, such as when maintaining or inspecting the water storage container, the valve can be closed to avoid inconvenience caused by the outflow of condensed water. By connecting the threaded insert 204 and the water storage container 206, the condensed water that has been initially filtered can be collected and stored for subsequent reuse in the steam boiler system, thereby improving the utilization rate of water resources.
[0034] A threaded connection pipe 202 is threadedly connected to the inner wall of the top end of the valve control component 203 , and the threaded connection pipe 202 is in communication with the connecting threaded insert 204 through the valve control component 203 .
[0035] The purpose of such a configuration is that when the device is in use, after the condensed water flows out of the filter, it first enters the threaded connecting pipe 202, then passes through the internal channel of the valve control component 203, and flows into the water storage container 206 through the connecting threaded insert 204, thereby further guiding the water flow path.
[0036] The filter 1 comprises a sealing shell 101 , on the inner wall of the bottom end of the sealing shell 101 a drain plug pipe 107 is threadedly connected, and the top end of the threaded connection pipe 202 is threadedly connected to the inner wall of the bottom of the drain plug pipe 107 .
[0037] The purpose of such a setting is that during the use of the device, after the condensed water is filtered by the filter element 102 in the filter 1, the impurities precipitate at the bottom of the sealed shell 101 and can be discharged through the sewage drain plug pipe 107. The filtered water flows out from the bottom of the sewage drain plug pipe 107, enters the threaded connection pipe 202, and then flows into the water storage container 206 through the valve control component 203 and the connecting threaded insertion pipe 204 in sequence.
[0038] The filter element 102 is fixedly installed inside the sealed shell 101. The top cover 103 is inserted on the inner walls around the top of the sealed shell 101, and a sealing ring 106 is fixedly sleeved on the outer wall of the overlapping part of the sealed shell 101 and the top cover 103.
[0039] The purpose of such a setting is that during the use of the device, the incoming condensed water is guided to the bottom of the filter element 102 through the guide pipe 108 and is filtered from bottom to top through the filter element 102 to remove impurities.
[0040] Flow pipes 105 are respectively opened on both sides of the top cover 103. A pressure gauge 104 is installed on the inner wall of the top of the top cover 103 and the flow pipe 105, and a threaded groove is clamped on the inner wall of the outer end of the flow pipe 105.
[0041] The purpose of such a setting is that during the use of the device, the condensed water enters the filter 1 from the flow pipe 105. The pressure gauge 104 installed on the flow pipe 105 monitors the internal pressure of the filter in real time. If the pressure rises abnormally, it may indicate problems such as filter element blockage, which is convenient for timely maintenance.
[0042] A guide pipe 108 is fixedly inserted into the inner wall of the middle part at the bottom end of the top cover 103, and the bottom end of the guide pipe 108 extends downward into the bottom hole groove of the filter element 102.
[0043] The purpose of such a setting is that during the use of the device, after the condensed water enters the top cover 103, it is guided to the bottom hole groove of the filter element 102 through the guide pipe 108, so that the condensed water has a more uniform flow path in the filter element, improving the filtering effect and ensuring that impurities can be fully intercepted.
[0044] During use, the condensed water generated by the steam boiler first enters the inside of the filter 1 from the flow pipes 105 on both sides of the top cover 103. During this process, the pressure gauge 104 installed on the inner wall of the top of the flow pipe 105 will monitor the internal pressure of the filter in real time. If the pressure rises abnormally, this may mean that problems such as blockage of the filter element 102 occur, and the staff can perform maintenance and processing in a timely manner based on this to ensure the normal progress of the filtering process;
[0045] The condensed water entering the top cover 103 will be guided through the diversion pipe 108 fixedly inserted in the inner wall of the middle part of its bottom end to the hole groove at the bottom of the filter element 102. Such a design enables the condensed water to have a more uniform and reasonable flow path in the filter element, ensuring sufficient contact between the condensed water and the filter element, thereby improving the filtration effect and allowing the impurities to be fully intercepted by the filter element. The condensed water flows upward from the bottom of the filter element 102. During this process, various suspended particles, impurities, etc. are blocked by the filter element, while the preliminarily purified condensed water continues to flow upward. At the same time, since a sealing ring 106 is fixedly sleeved on the outer wall of the overlapping part of the sealing shell 101 and the top cover 103, the sealing performance inside the filter is ensured, preventing the condensed water from leaking out without passing through the filter element.
[0046] The condensed water filtered by the filter element continues to flow upward to the bottom of the sealing shell 101. A drain plug pipe 107 is threadedly connected to the inner wall of the bottom end of the sealing shell 101. The impurities precipitated at the bottom of the sealing shell during the filtration process can be discharged by periodically opening the drain plug pipe 107 to maintain the cleanliness inside the filter and ensure the stability of the filtration effect. The filtered condensed water then flows out of the filter 1 from the bottom of the drain plug pipe 107.
[0047] The filtered condensed water flowing out from the bottom of the drain plug pipe 107 enters the threaded connection pipe 202 threadedly connected to the inner wall of the bottom of the drain plug pipe. The threaded connection pipe 202 is threadedly connected to the inner wall of the top end of the valve control component 203, and the condensed water thus flows into the valve control component 203. Threaded grooves are respectively opened on the inner walls of the upper and lower ends of the valve control component 203, and a connecting threaded insertion pipe 204 is threadedly connected to its bottom end. Through the channel inside the valve control component 203, the condensed water can flow into the connecting threaded insertion pipe 204. The valve control component 203 plays a key control role. The staff can, according to actual needs, operate the valve control component to open or close the water flow channel. When the valve is in the open state, the condensed water can flow through smoothly; while when it is necessary to maintain, inspect the subsequent water storage container 206, or when the condensed water is not required to continue flowing in, the valve can be closed to cut off the water flow.
[0048] A sealing cover 205 is fixedly sleeved on the bottom end of the connecting threaded insertion pipe 204. The water storage container 206 is threadedly connected to the inner wall of the sealing cover 205, and the valve control component 203 communicates with the cavity of the water storage container 206 through the connecting threaded insertion pipe 204. The condensed water passing through the valve control component 203 and the connecting threaded insertion pipe 204 finally flows into the water storage container 206 for storage. The water storage container is used to collect the condensed water after preliminary filtration treatment. These stored condensed water can be recycled to the steam boiler system later to achieve the recycling of water resources and the purpose of energy conservation and emission reduction.
[0049] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the present utility model to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification.
