Description

Technical Field

[0001] The utility model relates to the technical field of steam drain recovery, in particular to a steam drain recovery device. Background Art

[0002] Household wastewater, such as laundry, generates a significant amount of wastewater. This wastewater treatment typically involves the use of a steam trap recovery system, which typically distills the wastewater to generate steam. A steam trap recovery system is a common automated device found in plumbing systems, primarily used to recover and reuse condensate from steam systems. Through a series of components, such as steam traps, pressure-reducing valves, filters, and drains, the system effectively removes superheated steam and condensate from the pipes, maintaining stable operation. The steam trap is the core component of the system, ensuring the timely discharge of condensate from the pipe system through automatic control while maintaining a stable steam pressure within the pipes. The pressure-reducing valve reduces steam pressure in the pipes to prevent damage to pipes and equipment. The filter and drain remove impurities and contaminants from the pipes, ensuring the cleanliness of the recovered water.

[0003] In the existing steam trap recovery device, it generally includes a steam recovery pipe, a connecting pipe, a discharge valve and a steam trap. During the use of the existing device, steam is transmitted through the steam recovery pipe. During the transmission process, the steam will dissipate heat in the steam recovery pipe to form cold chain water droplets. The cold chain water droplets will enter the discharge valve through the connecting pipe on the one hand and be discharged through the control of the discharge valve. On the other hand, they will enter the interior of the steam trap and be recovered through the steam trap. The steam trap is a device installed on various liquid pipelines in the pipeline. Its main function is to prevent the fluid from leaking from one end of the valve channel and Automatically discharge condensate, but in the use of the existing overall device, the function of the steam trap is mainly to drain the steam pipe. In the steam pipe, when the steam releases heat and condenses, its volume shrinks instantly, forming a vacuum area. The condensed water in the pipe will be sucked into this vacuum area at high speed. This situation will form water hammer, and the steam trap is used to discharge the air in the steam system and the condensed water generated after the steam is used. When the drainage is not thorough, that is, the accumulated water will still enter the downstream pipeline under the drive of the steam flow, which is a great waste. In addition, the water hammer phenomenon caused by incomplete drainage will also cause damage to the pipeline.

[0004] Therefore, it is necessary to provide a new steam trap recovery device to solve the above technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a steam drain recovery device.

[0006] The steam drainage recovery device provided by the utility model comprises a steam recovery pipe and a recovery body arranged at the bottom of the steam recovery pipe, a fixed pipe is arranged on one side of the steam recovery pipe, a connecting assembly is arranged between the fixed pipe and the steam recovery pipe, the fixed pipe is connected to the steam recovery pipe through the connecting assembly, the diameter of the fixed pipe is smaller than the diameter of the steam recovery pipe, a guide plate is further arranged inside the steam recovery pipe, the bottom of the guide plate is fitted with the inner wall of the steam recovery pipe, two arc-shaped collecting grooves are arranged on the guide plate, two partitions are fixedly arranged on one side of the steam recovery pipe relative to the guide plate, the two partitions correspond to the positions of the two collecting grooves, and a plurality of guide grooves are provided on both partitions.

[0007] Preferably, the recovery body includes a connecting pipe and a drain valve, the connecting pipe is configured as a three-way pipe, the upper end of the connecting pipe is connected to two collecting tanks respectively, a water storage tank is installed at the bottom end of the connecting pipe, a fixed group is provided on the side of the connecting pipe close to the water storage tank, the drain valve is connected to the connecting pipe through the fixed group, and a water outlet pipe is fixedly installed on one side of the drain valve.

[0008] Preferably, the fixing group includes a connecting pipe and a control valve, one end of the connecting pipe is connected to the communicating pipe, the control valve is installed on the connecting pipe, and one end of the connecting pipe away from the control valve is fixedly connected to one side of the steam trap.

[0009] Preferably, the connecting assembly includes a fixing ring and fixing bolts, the inner side wall of the fixing ring is fixedly connected to the outer side wall of the fixed pipe, a plurality of fixing bolts are provided, and the fixing ring is connected to the steam recovery pipe via the plurality of fixing bolts.

[0010] Preferably, a discharge pipe is fixedly connected to the bottom of the water storage tank.

[0011] Preferably, a discharge valve for controlling the discharge of water in the discharge pipe is installed on the discharge pipe.

[0012] Compared with the related art, the steam drain recovery device provided by the utility model has the following beneficial effects:

[0013] 1. The device is provided with a fixed pipe. Since the diameter of the fixed pipe is smaller than that of the steam recovery pipe, when the steam enters the steam recovery pipe from the fixed pipe, when the steam enters the steam recovery pipe from the fixed pipe with a smaller diameter into the steam recovery pipe with a larger diameter, although the volume flow rate of the gas remains unchanged, due to the increase in the cross-sectional area of ​​the pipe, the gas is distributed in a larger space. In order to maintain the conservation of the volume flow rate, the flow rate of the gas must be reduced. The reduction in the steam flow rate can, on the one hand, improve the heat transfer efficiency in the steam pipe, and on the other hand, slow down the driving effect of the accumulated water during the steam transmission process, reduce the accumulated water entering the downstream pipe and cause large waste. In addition, the slowing down of the flow rate can reduce the impact force of the steam on the pipe wall, reduce the vibration of the pipe and equipment, and reduce the damage to the system caused by water hammer.

[0014] 2. The device is provided with a guide plate and a partition. Due to the setting of the fixed pipe and the steam recovery pipe, the steam transmission rate in the steam recovery pipe is slowed down, so that the steam can stay in the steam recovery pipe for a longer time. In this process, by setting the partition, when the steam encounters the partition, since the temperature of the partition is lower than the dew point temperature of the steam, the steam will release latent heat and convert into a liquid water column. Under the action of gravity, the water droplets will fall into the inside of the collecting trough set on the guide plate below, and the recovered distilled water will be discharged through the collecting trough. The setting of the partition and the use of the fixed pipe further increase the steam recovery amount and further reduce the waste of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the specific implementation process, Figure 1-Figure 5 As shown, a steam drain recovery device includes a steam recovery pipe 1 and a recovery body arranged at the bottom of the steam recovery pipe 1, a fixed pipe 2 is provided on one side of the steam recovery pipe 1, a connecting assembly is provided between the fixed pipe 2 and the steam recovery pipe 1, the fixed pipe 2 is connected to the steam recovery pipe 1 through the connecting assembly, the diameter of the fixed pipe 2 is smaller than the diameter of the steam recovery pipe 1, and a guide plate 13 is further provided inside the steam recovery pipe 1, the bottom of the guide plate 13 is in contact with the inner side wall of the steam recovery pipe 1, and two arc-shaped collecting grooves 12 are provided on the guide plate 13. Two partitions 14 are fixedly provided on one side of the steam recovery pipe 1 relative to the guide plate 13, and the two partitions 14 correspond to the positions of the two collecting grooves 12, and the two partitions 14 are both provided with a plurality of guide flow grooves 11;

[0024] During use, when steam encounters the partition 14, the temperature of the partition 14 is lower than the dew point of the steam, so the steam releases latent heat and turns into a liquid water column. Under the action of gravity, the water droplets fall into the collecting groove 12 provided on the guide plate 13 below. The provision of the guide groove 11 makes the water drop location more concentrated.

[0025] The recovery body includes a connecting pipe 4 and a drain valve 10. The connecting pipe 4 is configured as a three-way pipe. The upper end of the connecting pipe 4 is connected to two collecting tanks 12 respectively. A water storage tank 5 is installed at the bottom end of the connecting pipe 4. A fixed group is provided on the side of the connecting pipe 4 close to the water storage tank 5. The drain valve 10 is connected to the connecting pipe 4 through the fixed group. A water outlet pipe is fixedly installed on one side of the drain valve 10.

[0026] The fixed group includes a connecting pipe 9 and a control valve 8. One end of the connecting pipe 9 is connected to the connecting pipe 4. The control valve 8 is installed on the connecting pipe 9. The end of the connecting pipe 9 away from the control valve 8 is fixedly connected to one side of the steam trap 10.

[0027] The connection assembly includes a fixing ring 3 and fixing bolts 15. The inner side wall of the fixing ring 3 is fixedly connected to the outer side wall of the fixed pipe 2. A plurality of fixing bolts 15 are provided. The fixing ring 3 is connected to the steam recovery pipe 1 through the plurality of fixing bolts 15.

[0028] The bottom of the water storage tank 5 is fixedly connected to a discharge pipe 7, on which a discharge valve 6 is installed for controlling the discharge of water in the discharge pipe 7. During actual use, a control valve 8 can control the outflow and locking of water in the water storage tank 5;

[0029] The steam trap 10 mentioned above is specifically an inverted bucket steam trap 10. The inverted bucket steam trap 10 is a steam trap 10 that works based on the density difference between condensed water and steam. It is an efficient, durable and widely used steam trap device.

[0030] The working principle of the present invention is as follows: when the device is in use, steam will enter the steam recovery pipe 1 from the fixed pipe 2. When the steam enters the steam recovery pipe 1 with a larger diameter from the fixed pipe 2 with a smaller diameter, although the volume flow of the gas remains unchanged, due to the increase in the cross-sectional area of ​​the pipe, the gas is distributed in a larger space. In order to maintain the conservation of the volume flow, the flow rate of the gas must be reduced. In the steam recovery pipe 1, the steam can stay in the steam recovery pipe 1 for a longer time. In this process, by setting the partition 14, when the steam encounters the partition 14, Since the temperature of the partition 14 is lower than the dew point temperature of the steam, the steam will release latent heat and convert into a liquid water column. Under the action of gravity, the water droplets will fall into the inside of the collecting trough 12 set on the guide plate 13 below. The recovered distilled water will be discharged to the connecting pipe 4 below through the collecting trough 12. Part of the water will enter the inside of the water storage tank 5 through the connecting pipe 4, and the discharge of water in the water storage tank 5 will be controlled by the discharge valve 6. The other part of the water will enter the inside of the steam trap 10 through the connecting pipe 9, and the distilled water generated by the steam will be recovered through the steam trap 10.
