Description

Technical Field

[0001] This utility model belongs to the field of intake manifold technology, specifically, it relates to an intake manifold device for a power plant compressed air system. Background Technology

[0002] In various types of power plants, the compressed air system plays a crucial role in cooling the gas for all control valves and equipment. Its stable operation directly affects the control accuracy and reliability of the power plant equipment. The layout of compressed air pipelines must balance efficiency, reliability, and economy. In traditional technology, compressed air systems typically use a single DN15 (1 / 2" or other specifications) inlet pipe, branching through tees, elbows, reducers, and other fittings to connect to various user terminals. However, this branching layout has the following drawbacks: 1. It requires a large number of tees, elbows, reducers, and other connecting fittings, increasing material costs and installation time; 2. The dispersed extension of branch pipelines leads to complex pipeline routes, intersections, and overlaps, reducing space utilization and affecting aesthetics; 3. The isolation valves at each user terminal are dispersed along the branch pipelines, requiring individual inspection and operation during operation, increasing the workload and operational risks for maintenance personnel; 4. Multiple pipe connection points are prone to leakage hazards, and the dispersed layout is not conducive to centralized monitoring and rapid fault diagnosis. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an intake manifold device for a power plant compressed air system, which enables centralized arrangement of pipelines for each user in the compressed air system, facilitating maintenance and repair operations, and ensuring the safe and stable operation of various types of power plants.

[0004] The present invention adopts the following technical solution.

[0005] An intake manifold device for a power plant compressed air system includes a steam drum, a reducer, and a branch pipe. The steam drum has an air inlet and a drain outlet at both ends. The reducer includes a first reducer and a second reducer. The first reducer is connected to the air inlet of the steam drum, and the second reducer is connected to the drain outlet of the steam drum. The end of the second reducer away from the steam drum is connected to a drain valve.

[0006] The steam drum is also provided with several branch pipe connection ports evenly distributed on both sides. Each branch pipe connection port is connected to the branch pipe through a branch pipe seat. The end of the branch pipe away from the steam drum is connected to the user pipeline through a branch valve.

[0007] Furthermore, the branch pipes are horizontally arranged on both sides of the steam drum, and several branch pipes are symmetrical about the central axis of the steam drum.

[0008] Furthermore, the length of the branch pipe is 120-200mm, and the spacing between adjacent branch pipes is 180-220mm.

[0009] Furthermore, the intake manifold device for the power plant compressed air system is connected to the intake pipeline of the compressed air system via a first reducer.

[0010] Furthermore, the end of the first reducer connected to the steam drum has a large diameter, while the end connected to the intake pipe has a small diameter.

[0011] The end of the second reducer connected to the steam drum has a large diameter, and the end connected to the drain valve has a small diameter.

[0012] The beneficial effects of this utility model are as follows, compared with the prior art:

[0013] 1. This device adopts a centipede-like arrangement with one inlet and multiple outlets, achieving integration and significantly reducing the amount of pipe fittings such as tees and elbows used, thereby reducing material costs and installation time.

[0014] 2. This device arranges branch pipes horizontally on both sides of the steam drum and connects them to user pipelines through branch valves, which facilitates centralized operation and maintenance, improves space utilization, and reduces the workload and operational risks of operators.

[0015] 3. This device reduces the number of connection points through integrated design, thereby reducing the risk of leakage. At the same time, its centralized layout facilitates centralized monitoring and rapid fault diagnosis, improving the operational reliability of the compressed air system. Attached Figure Description
