Embodiment Construction

[0015] The present invention proposes an installation structure for direct air-cooling unit internal deflectors, which will be described below in conjunction with the accompanying drawings.

[0016] Such as figure 1 The deflector frame and installation structure shown include the deflector frame for fixing the relative position between the deflectors, the support structure for determining the relative position between the deflector frame and the air-cooling unit, and the suspension anti-corrosion device of the entire deflector. Vibration structure; direct air-cooling unit deflector 4 is symmetrically arranged on both sides of the air-cooling unit, located between the air-cooling unit walkway 6 and the fin tube bundle 7, the deflector frame 3 is connected to the air-cooling unit walkway 6 through its support structure 5 , and is connected with the air-cooling unit truss 2 through its suspension anti-vibration structure 1 .

[0017] Such as figure 2 As shown in a, the deflect...

Abstract

The invention discloses a direct air cooling unit interior guide plate framework and a mounting structure thereof, and belongs to the field of cooling system of power stations. A guide plate framework and support thereof, and a suspension structure compose a mounting fixation measure for a cooling air guide plate of a direct air cooling unit. The guide plate framework can determine relative positions of the guide plates; a guide plate framework support structure is the main stressed part of the guide plate framework, and the guide plate framework is fixed at an exact position inside the air cooling unit at the same time; the suspension structure of the guide plate framework absorbs vibration energy generated by the guide plate framework and the support structure thereof when the air cooling system is running, so that safe and stable running of the direct air cooling system of the power station is ensured.

Description

technical field [0001] The invention belongs to the field of cooling systems of power stations, and in particular relates to an internal deflector frame of a direct air cooling unit and an installation structure thereof. Background technique [0002] Due to its significant water-saving advantages, direct air cooling technology has been widely used in coal-fired power stations in my country's coal-rich and water-scarce northern regions in recent years. The direct air-cooling system consists of dozens of air-cooled condenser units arranged in a rectangular array. The finned tube bundles of the air-cooling unit are in an A-shaped structure and are arranged on both sides of the unit. Axial flow fans are installed at the bottom of the air-cooling unit for forced ventilation. The exhaust steam of the steam turbine in the finned tube bundle is cooled. [0003] Since the cooling air at the outlet of the axial flow fan rotates clockwise and flows upward, the distribution of the cool...
