DETAILED DESCRIPTION
[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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0024] See also Figure 1-6 The bottom of the inner cavity of the preheating tube 2 is provided with a steam inlet component 16 for facilitating the entry of external steam. By providing the steam inlet component 16, it can be connected to the boiler exhaust pipe, so that the excess high-temperature steam produced during the operation of the boiler can smoothly enter the inner cavity of the preheating tube 2, which is beneficial to the heat recovery work of the condensing component 6 and avoids the waste of heat energy caused by the direct discharge of high-temperature steam. The inner wall of the preheating tube 2 is provided with a heat preservation component 13 for slowing down the loss of steam heat. By providing the heat preservation component 13, the heat preservation component 13 can be used to prevent the heat loss of steam from being lost. The heating component 13 can effectively reduce the heat exchange rate between the high-temperature steam and the air outside the preheating cylinder 2, thereby avoiding the loss of high-temperature steam heat and improving the steam heat utilization rate; an insulated water tank 3 is provided on one side of the preheating cylinder 2, the bottom of the insulated water tank 3 is connected to the bottom plate 1, and a water storage chamber 17 is provided inside the insulated water tank 3; a heating component 18 is provided outside the water storage chamber 17 to heat the water twice. By providing the heating component 18, the supply water in the water storage chamber 17 can be kept at a high temperature in the period before entering the boiler, thereby avoiding the sudden drop in temperature of the supply water in the period before entering the boiler, which may affect the heating stability of the boiler; a sealing top cover 14 is installed at the top opening of the preheating cylinder 2, and an exhaust component 15 is provided on the top of the sealing top cover 14 to stabilize the air pressure inside the preheating cylinder 2. By providing the exhaust component 15, the heat of the high-temperature steam will become liquid after being recovered by the condensation component 6, and the excess air will be discharged to the outside of the preheating cylinder 2 through the exhaust component 15, thus facilitating the continuous entry of high-temperature steam and the continuous preheating work.
[0025] The condensing assembly 6 includes a heat-conducting tube 61 arranged inside the accommodating chamber 5. There are no less than three heat-conducting tubes 61, and the multiple heat-conducting tubes 61 are concentrically arranged. The diameter of the heat-conducting tube 61 increases gradually from the inside to the outside. The heat-conducting tubes 61 are nested and assembled from large to small and then loaded into the accommodating chamber 5. A spiral tube 63 is fixedly installed inside the heat-conducting tube 61, and multiple heat-conducting plates 62 are vertically installed on the outside of the heat-conducting tube 61. In actual use, the material of the heat-conducting tube 61, the heat-conducting plate 62, and the spiral tube 63 can be copper or steel. The staff can choose according to actual production needs; the axis of the heat-conducting plate 62 and the heat-conducting tube 61 are in the same plane, such as Figure 4 、 Figure 5 As shown, a plurality of heat-conducting tubes 61 nested from large to small and the heat-conducting plates 62 on their outer sides cooperate with the through space formed by the accommodating chamber 5. On the one hand, it conforms to the characteristic of high-temperature steam expanding and rising due to heat, which is conducive to the passage of high-temperature steam. On the other hand, it greatly increases the contact area with the high-temperature steam. The high-temperature steam rising along the gap between the accommodating chamber 5 and the condensation component 6 transfers heat to the heat-conducting tube 61 and the heat-conducting plate 62 along the way. The heat-conducting tube 61 and the heat-conducting plate 62 then transfer the heat to the supply water inside the spiral tube 63. In this way, the supply water is preheated by recovering and reusing the heat of the high-temperature steam, saving thermal energy resources.
[0026] The top and bottom of the inner cavity of the accommodating chamber 5 are fixedly installed with support rods 9, and the heat conducting tube 61 is respectively connected to the support rods 9 at both ends. The top of the upper support rod 9 is provided with a water inlet main pipe 12, and the top of the water inlet main pipe 12 passes through the outside of the accommodating chamber 5, and the bottom end of the water inlet main pipe 12 is symmetrically connected to multiple second distribution pipes 20. The top of the spiral tube 63 is connected to the water inlet branch pipe 7, and the top end of the water inlet branch pipe 7 passes through the support rod 9 and is connected to the second distribution pipe 20. The bottom of the support rod 9 is provided with a water outlet main pipe 11, and the top of the water outlet main pipe 11 is symmetrically connected to multiple first distribution pipes 10, and the bottom end of the spiral tube 63 is connected to the water outlet branch pipe 8, and the bottom end of the water outlet branch pipe 8 passes through the support rod 9 and is connected to the first distribution pipe 10. A second water pump 19 is fixedly installed on the top of the insulated water tank 3, and the water outlet of the second water pump 19 is connected to the water inlet of the water storage chamber 17. The bottom end of the water outlet main pipe 11 passes through the outside of the accommodating chamber 5 and is connected to the water inlet of the second water pump 19. Figure 3 、 Figure 4 As shown, the condensation assembly 6 is supported by two support rods 9 inside the accommodating chamber 5, and the supply water is distributed to each condensation assembly 6 at the same time by using the water inlet branch pipe 7 and the second distribution pipe 20. In this way, the supply water flow is refined, and the contact area with the high-temperature steam is further increased, which is beneficial to improving the preheating effect of the supply water. In addition, the staff can set the number of accommodating chambers 5 and condensation assemblies 6 according to the actual steam output of the boiler and the supply water temperature.

A drain pipe 163 is connected to the bottom of the preheating cylinder 2. A solenoid valve is installed inside the drain pipe 163. Figure 2 As shown, the steam outlet 162 is arranged at the bottom of the steam input pipe 161, which can prevent condensed water from dripping into the steam input pipe 161 and affecting the entry of high-temperature steam, and the condensed water with residual heat can be transferred to the outside of the external preheating cylinder 2 through the drainage pipe 163, which can be used for daily cleaning water in the factory area.
[0028] The heat preservation component 13 includes a hollow interlayer 131 arranged inside the preheating cylinder 2, and a first heat preservation layer 132 is provided on the inner wall side of the hollow interlayer 131 close to the accommodating cavity 5, and a heat insulation layer 133 is provided on one side of the first heat preservation layer 132. The first heat preservation layer 132 is made of polystyrene foam material, and the heat insulation layer 133 is made of rigid polyurethane foam material. Figure 3 As shown, the first thermal insulation layer 132 and the heat insulation layer 133 inside the hollow interlayer 131 can effectively reduce the heat exchange rate between the high-temperature steam and the air outside the preheating cylinder 2, thereby avoiding the loss of heat from the high-temperature steam.
[0029] The heating assembly 18 includes a spiral heating wire 185 fixed to the outside of the water storage chamber 17, a thermostat 186 is fixedly installed on one side of the insulated water tank 3, the spiral heating wire 185 is connected in series with the terminal of the thermostat 186 through a wire, a second insulation layer 184 is provided on the outside of the spiral heating wire 185, and the second insulation layer 184 is made of insulating asbestos material. A first water pump 182 is fixedly installed on the bottom of one side of the insulated water tank 3, and a second water supply pipe 183 is connected to the bottom of the water storage chamber 17. The bottom end of the second water supply pipe 183 passes through the insulated water tank 3 and is connected to the water inlet of the first water pump 182. The water outlet of the first water pump 182 is connected to the first water supply pipe 181, as shown in FIG. Figure 6 As shown, the spiral heating wire 185 and the temperature controller 186 can keep the supply water in the water storage chamber 17 at a high temperature before it enters the boiler. In combination with the second insulation layer 184, the temperature of the supply water can be prevented from dropping suddenly before it enters the boiler, thereby preventing the heating stability of the boiler from being affected.
[0030] The exhaust assembly 15 includes an air outlet pipe 151 fixed to the top of the sealing top cover 14, a water retaining cover 152 is provided above the air outlet pipe 151, and a plurality of connecting rods 153 are symmetrically installed at the bottom of the water retaining cover 152. The bottom ends of the connecting rods 153 are connected to the air outlet pipe 151. Figure 1 、 Figure 2 As shown, by setting up the air outlet pipe 151, the excess air can be quickly discharged from the inside of the preheating cylinder 2 after the heat of the high-temperature steam is recovered by the condensation component 6, thereby facilitating the continuous entry of high-temperature steam and the continuous preheating work.
[0031] Working principle: First, the steam inlet component 16 is connected to the boiler exhaust pipe, so that the excess high-temperature steam produced during the operation of the boiler can smoothly enter the preheating cylinder 2, and then the steam heat is recovered and reused in a heat exchange manner through the condensing component 6, so that the recovered steam heat is used to preheat the supply water in advance. In this way, the heat energy required for preheating the supply water is shared, achieving energy-saving effects, and avoiding the direct entry of cold water into the boiler, resulting in a decrease in steam production and unstable air pressure. Then, the heating component 18 is used to keep the supply water in the water storage chamber 17 at a high temperature before it enters the boiler, avoiding the sudden drop in temperature of the supply water before it enters the boiler, which affects the stability of the boiler heating supply.
