Description

Technical Field

[0001] This utility model relates to the field of BDO production equipment, and in particular to a pressure regulation and control system for a condensate tank based on a BDO heating system. Background Technology

[0002] During BDO production, the condensate from the double-layer unit and the outer pipe gallery within the equipment is recycled to the condensate tank connected to one of the units in the heat exchange station. The medium-pressure condensate pressure in this tank is relatively high, while the condensate from other units in the heat exchange station is recycled to the condensate tank at a lower pressure. As a result, flash evaporation occurs in the condensate tank, leading to high pressure inside the tank. At the same time, the alternating hot and cold temperatures of the medium-pressure and low-pressure condensate cause water hammer to frequently occur in the condensate tank, which can easily damage the equipment and pipelines.

[0003] Therefore, it is necessary to develop a pressure regulation and control system for the condensate tank of a BDO-based heating system to solve the above-mentioned technical problems. Utility Model Content

The outlet of the condensate tank is connected to a pump unit via a pipeline. A pressure regulating unit for regulating the internal pressure is connected to the top of the condensate tank.

[0007] Based on the above technical solution, the present invention can be further improved as follows.

[0008] Furthermore, the pressure regulating unit includes a venting line, and the top of the condensate tank is provided with a vent port, with one end of the venting line connected to the vent port.

Detailed Implementation

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example 1

[0025] like Figure 1As shown, the condensate tank pressure regulation and control system of the BDO-based heating system in this embodiment includes a condensate tank 1. The inlet of the condensate tank 1 is connected to the condensate pipeline 11 of the double-layer unit, the condensate pipeline 12 of the heat exchange station unit, the condensate pipeline 13 of the outer pipe gallery, and the condensate pipeline 14 of the gas distribution cylinder through multiple pipelines. The outlet of the condensate tank 1 is connected to a pump unit through a pipeline. The top of the condensate tank 1 is connected to a pressure regulating unit 2 for regulating its internal pressure.

[0026] The condensate tank pressure regulation and control system of the BDO-based heating system in this embodiment can promptly adjust the pressure in condensate tank 1 through pressure regulation unit 2 when flash evaporation of condensate occurs in condensate tank 1, resulting in high pressure in condensate tank 1, and / or when water hammer occurs due to the alternating hot and cold temperatures of medium-pressure condensate and low-pressure condensate entering condensate tank 1. This improves the problem of increased flash evaporation pressure and water hammer in condensate tank 1. The overall structure is simple and reasonable, effectively stabilizing condensate tank pressure, reducing water hammer, and fundamentally reducing equipment safety hazards and the risk of equipment damage.

[0027] In a preferred embodiment, the pressure regulating unit 2 includes a vent line 21, and the top of the condensate tank 1 is provided with a vent port, with one end of the vent line 21 connected to the vent port.

[0028] In the above implementation scheme, by setting up a venting pipeline 21 connected to and communicating with the condensate tank 1, the steam inside the condensate tank 1 is discharged and pressure is regulated by the venting pipeline 21 after initial flash evaporation and / or water hammer phenomenon occurs in the condensate tank 1, thereby effectively reducing the pressure inside the condensate tank 1 and improving the water hammer phenomenon. The pressure regulating unit 2 is relatively simple in design and relatively simple and quick to operate.

[0029] It should be noted that: in this embodiment, the pressure regulation and control system for the condensate tank of the heating system based on BDO selects a suitable point on the top of the original condensate tank 1, takes the point and makes a hole, and welds a venting interface at the hole. The venting interface matches one end of the venting pipeline 21 and is assembled in a quick-connect manner.

[0030] In this embodiment, the pressure regulating unit 2 can also be other devices on the market with similar functions (such as pressure relief function).

[0031] As a preferred embodiment, the vent line 21 is provided with a one-way valve to prevent gas from flowing back into the condensate tank 1.

[0032] In the above implementation scheme, the one-way valve can prevent gas from flowing back into the condensate tank 1 through the vent line 21, thus achieving a better pressure regulation effect.

[0033] In a preferred embodiment, the vent line 21 is provided with a control valve 22.

[0034] In the above implementation scheme, the flow state of the medium in the venting pipeline 21 can be controlled by the control valve 22. Especially during maintenance or temporary shutdown for adjustment, the flow of the medium in the venting pipeline 21 can be interrupted by directly operating the control valve 22, which is safe and convenient to operate.

[0035] In a preferred embodiment, the control valve 22 is an electrically controlled valve and is connected to a controller.

[0036] In the above implementation scheme, the control valve 22 is an electrically controlled valve (which can be a compatible solenoid valve) connected to the controller. The controller can intelligently control the opening and closing state of the electrically controlled valve, which is very convenient and efficient with one-button operation.

[0037] As a preferred implementation method, such as Figure 2 As shown, the top of the condensate tank 1 is provided with a pressure detection port, and a pressure detector 23 is provided at the pressure detection port.

[0038] In the above implementation scheme, a pressure detector 23 is connected to the top of the condensate tank 1. The pressure detector 23 can monitor the pressure change in the condensate tank 1 in real time. When the pressure exceeds the set value, the control valve 22 can be opened to release the steam in the condensate tank 1, thereby performing an effective pressure regulation operation.

[0039] In a preferred embodiment, the pressure detector 23 is a pressure transmitter and is connected to the controller.

[0040] In the above implementation scheme, the pressure detector 23 adopts a commercially available pressure transmitter and is connected to the controller together with the control valve 22. When the pressure in the condensate tank 1 exceeds the set value, the controller receives the information fed back by the pressure detector 23 and controls the control valve 22 to open for discharge in real time, realizing intelligent pressure regulation control without manual operation, saving time and effort.

[0041] It should be noted that in this embodiment, the controller can also be connected to an alarm. When the pressure inside the condensate tank 1 exceeds the set value, the information is fed back to the controller, which can then control the alarm to sound, thereby alerting the staff to take timely action.

[0042] For the alarm, any compatible model of audible and visual alarm can be used.

[0043] In a preferred embodiment, the controller is connected to a control terminal via a communication module.

[0044] In the above implementation scheme, the controller is connected to the intelligent control terminal in the background through network communication, and staff can monitor it in real time in the background, making the whole system more intelligent and improving security to a certain extent.

[0045] In this embodiment, the controller is an industrial computer of a compatible model commonly used in BDO production equipment or other existing control devices.

[0046] In a preferred embodiment, the vent line 21 is provided with a flow regulating valve 24.

[0047] In the above implementation scheme, the flow rate of the venting pipeline 21 can be adjusted by the flow regulating valve 24, so that the venting pipeline 21 can effectively vent and regulate pressure at a suitable flow rate.

[0048] In this embodiment, the flow regulating valve 24 can be a compatible solenoid valve and connected to a controller to achieve intelligent and automated flow regulation, saving labor.

[0049] As a preferred implementation method, such as Figure 3 As shown, the downstream section of the aforementioned venting pipeline 21 is connected to a steam trap 25.

[0050] In the above implementation scheme, since the venting pipeline 21 mainly discharges steam, a steam trap 25 is connected to the venting pipeline 21 to condense the steam. A circulation pipeline can also be connected at the end to circulate the condensed water back to the pipeline where the BDO equipment needs water, thereby realizing the recycling of resources.

[0051] In this embodiment, the drain condensate 25 can be any commercially available model, and its function and structure will not be described in detail here.
