Description

Technical Field

[0001] This utility model belongs to the field of condensate recovery technology, specifically relating to a high-temperature steam condensate recovery device. Background Technology

[0002] High-temperature steam condensate refers to water formed by the condensation of steam after it releases latent heat, and its temperature is close to the saturation temperature of the steam. In industrial applications, steam condensate typically has a high temperature.

[0003] A Chinese patent with publication number CN219015028U discloses a high-temperature steam condensate recovery device, comprising a steam condensate discharge pipe, a circulating water tank and a circulating pump connected by pipes, and circulating water placed in the circulating water tank. The device is characterized in that the lower section of a recovery cylinder is placed in the circulating water, the end of the steam condensate discharge pipe passes through the recovery cylinder and is placed below the surface of the circulating water inside the cylinder, and the outlet of the circulating pump is connected to a nozzle through a circulating pipe. The nozzle is placed inside the recovery cylinder above the surface of the circulating water. In use, steam condensate is introduced into the recovery cylinder below the surface of the circulating water through the steam condensate discharge pipe. The liquid seal formed by the insertion depth of the steam condensate discharge pipe increases the condensate outlet pressure, thereby preventing flash evaporation and the generation of secondary steam due to reduced outlet pressure. The low-temperature circulating water in the circulating water tank exchanges heat with the high-temperature condensate, with a large amount of circulating water carrying away the heat from the condensate. Simultaneously, the nozzle sprays water inside the recovery cylinder, preventing the leakage of small amounts of water vapor and thus preventing environmental pollution.

[0004] Regarding the aforementioned technologies, the inventors have discovered at least the following problems: High-temperature steam condensate is not completely pure; it carries impurities from the boiler or pipelines. If high-temperature steam condensate containing impurities is directly discharged into the circulation pool, it will pollute the water in the circulation pool after direct contact, leading to a decline in water quality. Even if the circulating water absorbs the heat from the high-temperature steam condensate, it reduces the utilization value of the circulating water. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature steam condensate recovery device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature steam condensate recovery device, comprising a working chamber, a filter chamber, a heat exchange chamber, and a recovery chamber, wherein the filter chamber, heat exchange chamber, and recovery chamber are sequentially arranged inside the working chamber. A steam condensate discharge pipe is fixedly connected to the top of the working chamber, and one end of the steam condensate discharge pipe is fixedly connected to the filter chamber. Two spaced filter screens are arranged inside the filter chamber. A first water pump is connected to one side of the filter chamber. An S-shaped heat exchange tube is fixedly installed inside the heat exchange chamber, and the outlet end of the first water pump is fixedly connected to one end of the heat exchange tube. A water guide pipe is fixedly connected to the other end of the heat exchange tube, and one end of the water guide pipe extends into the recovery chamber. A second water pump is connected to one side of the recovery chamber.

[0007] In a preferred embodiment, the work box has a double door hinged to the front, and the double door is provided with a viewing window and a control panel respectively.

[0008] In a preferred embodiment, the two filters have different mesh sizes, with the filter with smaller mesh size located below the filter with larger mesh size.

[0009] In a preferred embodiment, a groove is provided on the inner wall of the filter box, the filter screen is slidably installed in the groove, and an opening is provided on one side of the filter box, with one end of the filter screen inserted into the opening.

[0010] In a preferred embodiment, a water inlet pump is connected to the top of the heat exchange box, a water pump is connected to the bottom of the heat exchange box, and a temperature sensor is installed inside the heat exchange box.

[0011] In a preferred embodiment, the recycling tank is equipped with a level gauge.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This high-temperature steam condensate recovery device, through the setting of a filter box, first discharges the high-temperature steam condensate from the steam condensate discharge pipe into the filter box, so that the two filter screens in the filter box can perform double filtration of impurities in the high-temperature steam condensate, and then recover the high-temperature steam condensate after impurity removal, which can improve the recovery quality of high-temperature steam condensate.

[0014] This high-temperature steam condensate recovery device, through the setting of a heat exchange box, can start the inlet pump to add pure water into the heat exchange box. After the high-temperature steam condensate is filtered in the filter box, the first water pump can be started to transport the high-temperature steam condensate to the heat exchange tube, so that the pure water in the heat exchange box absorbs the heat of the high-temperature steam condensate in the heat exchange tube. When the temperature sensor detects that the temperature of the pure water in the heat exchange box has risen to a certain temperature, the water pump can be started to discharge the hot water in the heat exchange box. In this way, the heat of the high-temperature steam condensate can be recovered without contacting the high-temperature steam condensate, avoiding the high-temperature steam condensate from affecting the quality of the pure water.

Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3This utility model provides a high-temperature steam condensate recovery device, including a working box 1, a filter box 2, a heat exchange box 3, and a recovery box 4. The filter box 2, heat exchange box 3, and recovery box 4 are arranged sequentially inside the working box 1. A steam condensate discharge pipe 11 is fixedly connected to the top of the working box 1. A double door 12 is hinged to the front of the working box 1. A viewing window 13 and a control panel 14 are respectively provided on the double door 12. One end of the steam condensate discharge pipe 11 is fixedly connected to the filter box 2. The filter box 2 is equipped with two spaced filter screens 21. The two filter screens 21 have different mesh sizes. The filter screen 21 with smaller mesh size is located below the filter screen 21 with larger mesh size. By setting up the filter box 2, when recovering high-temperature steam condensate, the high-temperature steam condensate is first discharged from the steam condensate discharge pipe 11 into the filter box 2, so that the two filter screens 21 in the filter box 2 can perform double filtration of impurities in the high-temperature steam condensate. Then, the high-temperature steam condensate after impurity removal is recovered, which can improve the recovery quality of high-temperature steam condensate.

[0022] The filter box 2 has a sliding groove 23 on its inner side wall. The filter screen 21 is slidably installed in the sliding groove 23. An opening is provided on one side of the filter box 2. One end of the filter screen 21 is inserted into the opening. The sliding groove 23 and the opening facilitate the disassembly and replacement of the filter screen 21.

[0023] Furthermore, a first water pump 22 is connected to one side of the filter box 2. An S-shaped arrangement of heat exchange tubes 31, made of copper, is fixedly installed inside the heat exchange box 3. The outlet end of the first water pump 22 is fixedly connected to one end of the heat exchange tubes 31. An inlet water pump 33 is connected to the top of the heat exchange box 3, and a pump 34 is connected to the bottom. A temperature sensor 35 is installed inside the heat exchange box 3. Based on these features, the inlet water pump 33 can be activated to add purified water to the heat exchange box 3. When high-temperature steam condenses... After filtration in the filter box 2, the first water pump 22 can be started to transport the high-temperature steam condensate to the heat exchange tube 31, so that the pure water in the heat exchange box 3 can absorb the heat of the high-temperature steam condensate in the heat exchange tube 31. When the temperature sensor 35 detects that the temperature of the pure water in the heat exchange box 3 has risen to a certain temperature, the water pump 34 can be started to discharge the hot water in the heat exchange box 3. In this way, the heat of the high-temperature steam condensate can be recovered without contacting the high-temperature steam condensate, thus avoiding the high-temperature steam condensate from affecting the quality of the pure water.

[0024] Furthermore, a water guide pipe 32 is fixedly connected to the other end of the heat exchange tube 31. One end of the water guide pipe 32 extends into the recovery tank 4. A second water pump 41 is connected to one side of the recovery tank 4. A level gauge 42 is installed inside the recovery tank 4. By setting up the recovery tank 4, a certain amount of water can be pre-added into the recovery tank 4 to submerge the outlet end of the water guide pipe 32. Then, the high-temperature steam condensate after heat exchange through the heat exchange tube 31 will be guided into the recovery tank 4 by the water guide pipe 32. The water in the recovery tank 4 increases the pressure when the high-temperature steam condensate is discharged from the water guide pipe 32, avoiding flash evaporation. As the high-temperature steam condensate is continuously discharged into the recovery tank 4, when the level gauge 42 detects that the liquid level in the recovery tank 4 has risen to a certain height, the second water pump 41 can be started to discharge the water in the recovery tank 4. When the level gauge 42 detects that the liquid level in the recovery tank 4 has dropped to a certain height, the second water pump 41 is stopped, so that a certain amount of water is always kept in the recovery tank 4 to submerge the outlet end of the water guide pipe 32.

[0025] The working principle and usage process of this utility model are as follows: First, the water inlet pump 33 can be started to add pure water into the heat exchange box 3, and a certain amount of water is pre-added to the recovery box 4 so that the water submerges the outlet end of the water guide pipe 32. When recovering high-temperature steam condensate, the high-temperature steam condensate is first discharged from the steam condensate discharge pipe 11 into the filter box 2, so that the two filter screens 21 in the filter box 2 perform double filtration of impurities in the high-temperature steam condensate. After the high-temperature steam condensate has been filtered in the filter box 2, the first water pump 22 can be started to transport the high-temperature steam condensate to the heat exchange tube 31, so that the pure water in the heat exchange box 3 absorbs the heat of the high-temperature steam condensate in the heat exchange tube 31. When the temperature sensor 35 detects the heat in the heat exchange box 3... After the temperature of the purified water rises to a certain level, the water pump 34 can be started to discharge the hot water in the heat exchange box 3. The high-temperature steam condensate after heat exchange through the heat exchange tube 31 will be guided into the recovery box 4 by the water guide pipe 32. The water in the recovery box 4 increases the pressure of the high-temperature steam condensate when it is discharged from the water guide pipe 32, thus avoiding flash evaporation. As the high-temperature steam condensate is continuously discharged into the recovery box 4, when the level gauge 42 detects that the liquid level in the recovery box 4 has risen to a certain height, the second water pump 41 can be started to discharge the water in the recovery box 4. When the level gauge 42 detects that the liquid level in the recovery box 4 has dropped to a certain height, the second water pump 41 is stopped, so that the recovery box 4 always maintains a certain amount of water submerging the outlet end of the water guide pipe 32.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
