Problems solved by technology

[0002] The currently known isolation baffle doors used for flue gas switching and isolation in flue gas desulfurization systems (FGD) are multi-axis louver structures, and a separate intermediate medium supply system is used to provide isolation media to ensure the flue gas on both sides of the baffle door. To achieve complete isolation, there are problems such as complex structure, complicated system, increased error probability, many possible leakage points, and easy entry of smoke and dust impurities into the sealed cavity.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Examples of the present invention are figure 1 , the actuator 1 is driven by a prime mover such as an electric motor or a cylinder, which is a commercially available stereotyped product. The sealing sheet 2 is made of elastic materials such as 316LMN stainless steel, C276 nickel-based alloy and other materials. The valve body 3 and the switching valve stator part 51 are integrally manufactured. The fixed valve plate 41, the movable valve plate 42, and the switching valve rotor part 5 are constructed of steel pipes.

[0016] Structurally, the present invention is composed of a windshield, a casing and a control device. The smoke isolation baffle damper includes a valve body 3 with a self-closing structure valve plate with a closed cavity, an intermediate medium control switching valve 5, and an electric actuator 1. ; wherein the electric actuator...

Abstract

The invention is a smoke insulating damper-throttle relating to a insulating block used for smoke switch and insulation in smoke desulphurizing system, it can realize insulation to smoke with simple and reliable structure, the throttle includes a valve of a closed structure valve board with a sealed cavity, a middle media control switching valve, a electric executing mechanism; the electric executing mechanism, the middle media control switching valve are at two sides of the valve, the self-closed structure valve board with sealed cavity is in the valve, one end is connected to the outer electric executing mechanism, another end is connected to the outer middle media control switching valve, the middle media control switching valve and the hollow part of the self-closed structure valve board are connected; the valve board can be driven by the electric executing mechanism to rotate 90 degrees, at the same time, it drives the middle media control switch valve to rotate 90 degrees. It integrates the middle media control switch system and the valve board control, it guarantees the safety and reliability of the seal.
