Description

Technical Field

[0001] This utility model relates to a novel low-pressure exhaust steam recovery device. Background Technology

[0002] Our main business includes providing heating services to surrounding industrial parks. Based on the steam usage of external heating users, the plant's heating flow rate needs to be adjusted in real time to ensure appropriate steam pressure. Because the steam usage of external heating users is uncontrollable, high heating pressure often necessitates opening bypass valves in the steam pipelines for pressure control, significantly increasing labor costs and wasting a considerable amount of clean steam. Furthermore, when new steam is introduced into the deaerator, air or other non-condensable gases (such as CO2) in the pipelines can hinder the contact between steam and water, affecting deoxygenation efficiency. The deaerator rapidly discharges these gases through its exhaust valve to ensure the equipment quickly establishes a normal deoxygenation environment, guaranteeing deoxygenation effectiveness and equipment safety, and creating conditions for subsequent efficient deoxygenation. However, the exhaust valve typically has a large opening and operates with a transient, high flow rate. With residential areas, schools, and commercial areas nearby, the steam jet noise can reach over 120dB when the deaerator exhaust valve is open, seriously endangering the health of on-site personnel and causing noise pollution to nearby residents, disrupting their daily lives. Utility Model Content

[0003] The purpose of this invention is to provide a novel low-pressure exhaust steam recovery device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a novel low-pressure exhaust steam recovery device, the structure of which includes a low-pressure steam header and a deaerator. The low-pressure steam header and the deaerator are connected by a first pipeline. An electric valve is installed on the first pipeline. The other end of the deaerator is connected to a silencer through an exhaust pipeline.

[0005] Preferably, the electric valve for the pipeline is located on the side of the first pipeline near the deaerator.

[0006] Preferably, an exhaust valve is provided on the exhaust pipe, and the exhaust valve is located on the side of the exhaust pipe near the deaerator.

[0007] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages:

[0008] 1. This utility model provides a novel low-pressure exhaust steam recovery device, in which a pipeline is led from the low-pressure steam header body to the deaerator, and the steam flow is controlled by an electric valve on the pipeline to achieve peak regulation of the pressure of the low-pressure steam header body.

[0009] 2. The present invention provides a novel low-pressure exhaust steam recovery device, which adds a silencer to the end of the deaerator exhaust pipe. The silencer reduces or eliminates the high-frequency noise generated when gas and steam are emitted, so that the noise at the exhaust port meets environmental protection standards, while preventing rainwater backflow.

[0016] Example

[0017] like Figure 1 As shown, a novel low-pressure exhaust steam recovery device includes a low-pressure steam header 1 and a deaerator 2. The low-pressure steam header 1 and the deaerator 2 are connected by a first pipe 3. An electric valve 4 is installed on the first pipe 3. The other end of the deaerator 2 is connected to a silencer 7 through an exhaust pipe 5.

[0018] like Figure 1 As shown, the electric valve 4 is installed on the side of the first pipe 3 near the deaerator 2.

[0019] like Figure 1 As shown, an exhaust valve 6 is installed on the exhaust pipe 5, located on the side of the exhaust pipe 5 closest to the deaerator 2. With this structure, when new steam is introduced into the deaerator, air or other non-condensable gases (such as CO2) in the pipe can hinder the contact between steam and water, affecting deoxygenation efficiency. The deaerator quickly discharges these gases through the exhaust valve, ensuring the equipment rapidly establishes a normal deoxygenation environment, guaranteeing deoxygenation effectiveness and equipment safety, and creating conditions for subsequent efficient deoxygenation.

[0020] The novel low-pressure exhaust steam recovery device provided by this utility model has two main advantages. First, it solves the problem of peak shaving caused by fluctuations in the external grid load of the low-pressure steam header 1. It allows for peak shaving through the electric valve 4 of the pipeline from the low-pressure steam header 1 to the deaerator 2, greatly reducing the labor costs previously required to open the drain bypass valves along the steam pipeline for pressure control. It also recovers a significant amount of clean steam for recycling. Second, it solves the problem of noise pollution caused by the loud noise when the exhaust valve 6 of the deaerator 2 is opened. By installing a silencer 7 at the end of the exhaust pipe 5 of the deaerator 2, the high-frequency noise generated during gas and steam discharge is effectively reduced or eliminated, ensuring that the noise at the discharge outlet meets environmental protection standards. At the same time, the silencer 7 effectively prevents rainwater backflow.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
