DETAILED DESCRIPTION
[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1
[0038] See also Figures 1 to 4 The utility model is a gas stove steam-water separator, comprising a gas drainer body 1 and an inner shell 102 arranged on the inner side thereof, an air inlet pipe 105 is arranged at the top rear end of the gas drainer body 1, a gas detection and cut-off component 2 is arranged directly above the air inlet pipe 105, an anti-air mass component 3 is arranged at the bottom end of the air inlet pipe 105, and an automatic temperature control heating component 4 is arranged on one side of the top of the gas drainer body 1; the gas detection and cut-off component 2 includes a gas detection system and an automatic shut-off valve device; the anti-air mass component 3 includes a grid frame, and the grid frame is installed at the bottom of the air inlet pipe 105; the automatic temperature control heating component 4 includes a temperature sensor and a control system.
[0039] Specifically, a base 101 is installed at the bottom of the gas drain body 1, a partition 1021 is arranged between the inner wall of the gas drain body 1 and the outer wall of the inner shell 102, a heating pipe 103 is arranged between the outer wall of the inner shell 102 and the inner wall of the partition 1021, an insulation layer 104 is arranged between the inner wall of the gas drain body 1 and the outer wall of the partition 1021, and the top of the air inlet pipe 105 is connected to the water gas pipe 1052 through a flange 1051. A cross partition 106 is fixedly connected to the inner wall of the inner shell 102, and filter tubes 1061 are provided on the tops of three adjacent end faces of the cross partition 106. A filter component 1062 is provided at the air inlet of the filter tube 1061. Drain pipes 107 are evenly spaced along the circumferential direction at the bottom end of the outer wall of the inner shell 102, and a drain valve 1071 is provided at the end of the drain pipe 107. An overflow pipe 108 is provided on the top of the outer wall of one side of the inner shell 102.
[0040] Furthermore, water-gas is separated from steam inside the inner shell 102. The gas detection system can monitor gas leakage in real time and close the water-gas pipe 1052 by controlling the automatic shut-off valve device. The grid frame can destroy the generation of air masses and improve the efficiency of steam-water separation. The ambient temperature and internal temperature are monitored by a temperature sensor, and the heating tube 103 is controlled by the control system for heating. The base 101 is equipped with a frame connection for easy installation and fixation. The insulation layer 104 uses environmentally friendly flame-retardant rock wool to improve safety. The cross partition 106 divides the inner shell 102 into four filter chambers to achieve quadruple filtration. A drain valve 1071 is provided on the drain pipe 107 to facilitate drain operation. The filtering component 1062 is used to filter and separate the water-gas.
[0041] The operation process of this embodiment is as follows: first, water gas is introduced through the water gas pipe 1052. After the water gas enters the interior of the air inlet pipe 105, it will pass through the anti-air mass component 3 arranged at the bottom thereof, wherein the anti-air mass component 3 is a grid frame. After the water gas passes through the grid frame, the air mass that rushes in can be broken up to prevent the regeneration of the air mass and prevent the air mass from entering the next filter cavity, thereby improving the steam-water separation efficiency and making the gas purification efficiency higher. After the water gas enters, the gas detection system in the gas detection cut-off component 2 on the water gas pipe 1052 detects in real time whether there is a gas leak, and after detecting a gas leak, the inlet air intake system is automatically cut off through the linkage control cut-off valve to ensure safety and eliminate hidden dangers. Under the action of the cross partition 106 The inner space of the inner shell 102 is divided into four filter chambers. After the water gas enters the inner chamber, it will be filtered through three groups of filter tubes 1061 and filter components 1062 in turn. The four-layer filtering and sewage discharge measures can greatly improve the filtering and treatment effect of the water gas. At the same time, the device is provided with an automatic temperature control heating component 4, which contains a temperature sensor and a related control system. When used in the cold winter in the north, the heater needs to be turned on frequently. If the maintenance personnel do not maintain it in time, it will cause freezing. An intelligent control system is added to the original heater. When the temperature drops to zero degrees Celsius, the heating function is automatically started, and the heating is stopped when the temperature reaches 15 degrees Celsius, ensuring the normal operation of the system, reducing the workload of maintenance personnel and improving efficiency. Specific embodiment 2
[0043] See also Figure 1 , 5 On the basis of the first specific embodiment, what is different from the first embodiment is that: a water floating seal assembly 5 is provided, the water floating seal assembly 5 includes a buoyancy box 501 and a float 502 placed at the center of the bottom end thereof, and a drain pipe 5012 is arranged at the center of the bottom of the buoyancy box 501, which solves the problem that the water seal of the existing gas furnace steam-water separator often leaks when in use, and there is a safety hazard if the gas leaks.
[0044] Specifically, a water inlet pipe 5011 is provided at the top of the outer wall of one side of the buoyancy box 501, and the other end of the water inlet pipe 5011 is connected to the overflow pipe 108 through a pipe joint. An air outlet pipe 5013 is provided at the top center of the buoyancy box 501, and an air outlet valve 503 is provided at the end of the air outlet pipe 5013.
[0045] Furthermore, as the amount of water inside the buoyancy box 501 increases, the float 502 will float up and open the top of the drain pipe 5012. Then, the water inside the buoyancy box 501 can be automatically discharged through the drain pipe 5012, and there will be no gas leakage.
[0046] The operation process of this embodiment is as follows: after the water gas is filtered, the sewage generated is discharged through the drain pipe 107 and is controlled accordingly by the drain valve 1071. The filtered gas is discharged from the gas outlet pipe 5013 through the overflow pipe 108 and the water inlet pipe 5011. As the amount of filtered water inside the inner shell 102 increases, the water enters the buoyancy box 501 through the overflow pipe 108 and the water inlet pipe 5011. As the amount of water inside the buoyancy box 501 increases, the float 502 is driven to move upward continuously. At the same time, the sealing effect of the float 502 on the top of the drain pipe 5012 can be cancelled. At this time, the water inside the buoyancy box 501 is automatically discharged through the drain pipe 5012. As the amount of water inside the buoyancy box 501 decreases, the float 502 descends and automatically seals the top of the drain pipe 5012 after the water is completely discharged, thereby improving the water floating sealing performance, ensuring that the gas does not leak, and having good safety performance.
