Description

Technical Field

[0001] This invention relates to the field of steam-powered heating condensate recovery device. Background Technology

[0002] The steam power heater uses steel-aluminum composite finned tubes as the main heat exchanger element, and uses the heat released by steam to heat the required process gases, etc.

[0003] According to the Chinese Patent Publication No. CN 113757002 B, "A Steam Heating Cylinder for Ship Fuel Tank", the cylinder is installed at the bottom of the fuel tank. The steam inlet pipe is connected to steam, and the steam enters the cylinder through the steam inlet pipe. The steam heats the fuel pipeline, and the fuel flows in the pipeline. The temperature of the steam in the cylinder is transferred to the fuel through heat transfer, so as to quickly raise the fuel temperature and reduce the fuel viscosity. Low-temperature fuel enters from the fuel inlet pipe and high-temperature fuel exits from the fuel outlet pipe, thereby completing the heating of the fuel.

[0004] However, the aforementioned device has a problem where, after the fuel oil is heated, the steam is cooled by the fuel oil and liquefies into condensate, which cannot be discharged from the heating cylinder. The remaining steam is then discharged into the environment through the steam outlet pipe, resulting in a waste of resources. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to improve the technology for recovering condensate generated by steam-powered heating and provides a steam-powered heating condensate recovery device. This device employs a scheme of recovering condensate through secondary cooling of steam. The beneficial effect is that the condensate reaches the interior of the steam-powered heater, achieving the effect of recycling and reusing the condensate, thus protecting water resources.

[0006] The objective of this invention is achieved as follows:

[0007] A steam-powered heating condensate recovery device includes: a main body and a recovery mechanism, wherein the recovery mechanism is disposed below the main body;

[0008] The main structure includes: a tank body, a feed pipe, a discharge pipe, a heat exchange pipe, a baffle, an air inlet pipe, and an air outlet pipe.

[0016] Beneficial effects:

[0017] Firstly, this steam-powered heating condensate recovery device has the effect of recycling condensate and protecting water resources: The object to be heated is fed into the heat exchange tube through the feed pipe. Steam then enters from the inlet pipe to exchange heat with the object inside the heat exchange tube. The steam is then cooled into condensate by the object inside the heat exchange tube, which falls onto the bottom wall of the tank. The still-heated steam is discharged from the outlet pipe into the steam box, where it is further cooled by cold air in the condenser tube, converting it back into condensate. This condensate then reaches the lower right side of the steam box and then into the water pipe. The condensate on the bottom wall of the tank and the condensate inside the steam box also reach the water pipe, and then both flow into the filter box. The condensate is filtered by the filter sponge inside the filter box, and then flows into the hot water tank, where it mixes with the hot water before reaching the steam-powered heater. This achieves the effect of recycling condensate and protecting water resources.

[0018] Secondly, this steam-powered heating condensate recovery device improves the mixing efficiency of condensate and hot water and accelerates the recycling speed: the motor drives the stirring rod to mix the condensate and hot water inside the hot water tank, which accelerates the mixing efficiency of condensate and hot water and improves the heating efficiency when it reaches the steam-powered heater, thus achieving the effect of improving the mixing efficiency of condensate and hot water and accelerating the recycling speed.

[0028] The recycling mechanism 2 includes: a steam box 201, a water pipe 202, a condenser pipe 203, a filter box 204, a hot water tank 205, a motor 206, a stirring rod 207, and a water outlet pipe 208. The water pipe 202 is fixedly connected to the bottom of the steam box 201, the condenser pipe 203 is fixedly connected to the inside of the steam box 201, the filter box 204 is fixedly connected to the bottom of the water pipe 202, the hot water tank 205 is fixedly connected to the bottom of the filter box 204, the motor 206 is located on the right side of the hot water tank 205, the stirring rod 207 is fixedly connected to the left side of the motor 206, and the water outlet pipe 208 is fixedly connected to the left side of the hot water tank 205.

[0029] Through the above technical solution, the object to be heated is fed into the heat exchange tube 104 through the feed pipe 102. Steam then enters from the air inlet pipe 106 to exchange heat with the object inside the heat exchange tube 104. The steam is then cooled into condensate by the object inside the heat exchange tube 104 and falls onto the bottom wall of the tank 101. The steam with remaining heat is discharged from the air outlet pipe 107 into the steam box 201. The steam is then cooled a second time by the cold air in the condenser pipe 203 and converted into condensate. The condensate then reaches the lower right side of the steam box 201 and then into the water pipe 202. The condensate on the bottom wall of the tank 101 reaches the water pipe 202, and the condensate inside the steam box 201 reaches the water pipe 202. They then all reach the filter box 204, where the condensate is filtered by the filter sponge. The filtered condensate then reaches the hot water tank 205, mixes with the hot water inside the hot water tank 205, and then reaches the steam power heater. This achieves the effect of recycling condensate and protecting water resources.

[0030] The motor 206 drives the stirring rod 207 to mix the condensate and hot water inside the hot water tank 205, which speeds up the mixing efficiency of the condensate and hot water and improves the heating efficiency when it reaches the steam power heater. This achieves the effect of improving the mixing efficiency of the condensate and hot water and accelerating the recycling speed.

[0031] Specifically, the discharge pipe 103 is located on the lower left side of the tank body 101, and the feed pipe 102 is fixedly connected above the heat exchange pipe 104 and the discharge pipe 103 is fixedly connected below it.

The object to be heated is fed into the heat exchange pipe 104 through the feed pipe 102. Then, steam enters from the air inlet pipe 106 to exchange heat with the object in the heat exchange pipe 104. The steam is then cooled into condensate by the object in the heat exchange pipe 104 and falls onto the bottom wall of the tank body 101. The steam with residual heat is discharged from the air outlet pipe 107 and reaches the steam box 201, thus realizing the collection of condensate and steam with residual heat.

[0034] Through the above technical solution, there are multiple sets of baffles 105, which are fixedly connected to the inner wall of the heat exchange tube 104. By using multiple sets of baffles 105 to block the items inside the heat exchange tube 104, the items inside the heat exchange tube 104 are in contact with the steam for a longer time, thereby absorbing more heat from the steam and saving steam resources.

[0036] Through the above technical solution, the upper right side of the vent pipe 107 is fixedly connected to the lower left side of the steam box 201. A vent valve is fixedly connected to the upper part of the steam box 201. Circular holes are opened on both sides of the steam box 201. The left and right sides of the condenser pipe 203 are fixedly connected to the circular holes opened on both sides of the steam box 201. Steam with residual heat is discharged from the vent pipe 107 into the steam box 201. Then, the steam is cooled a second time by the cold air in the condenser pipe 203 and then converted into condensate. The condensate then reaches the lower right side of the steam box 201. The lower part of the steam box 201 is angled and then reaches the water pipe 202 for easy collection of condensate. The vent valve above the steam box 201 can prevent the internal gas pressure of the device from being too high. This vent valve is existing technology and achieves the effect of cooling and recovering steam with residual heat.

Then, the filtered condensate reaches the inside of the hot water tank 205 and mixes with the hot water inside the hot water tank 205. This facilitates the heating efficiency of the hot water by the steam power heater and achieves the effect of recycling the condensate and protecting water resources.

[0041] Specifically, the motor 206 is screwed to the right side of the hot water tank 205, and the stirring rod 207 extends to the left side of the inner wall of the hot water tank 205.
