Flue gas desulfurization bezel door

Product description

The regulatory plate flap is used to regulate the media flow in the boiler smoke pipe, and to control the pressure, temperature, quantity and other parameters of the medium in the system by different medium flow in different positions within 90 degrees of leaf rotation. It has the characteristics of flexible rotation and excellent regulation. The wind gate introduces the design and production of EC technology in the United States, using the relative action type of adjacent blades. The regulatory plate flap adopts the steel plate compression welding structure, and the blade is a streamlined diamond-shaped structure at the sharp corners of both ends, which can change the distribution of the tail stream of the air flow. Its adjustment characteristics are in the blade opening range of 25 to 75 degrees, the resistance coefficient and opening degree in an approximate linear ratio relationship; For the valve of the positive pressure hot air system, the shaft end bearing is equipped with a sealed air interface that can be connected to the sealed air to block the heat inside and outside. The regulating door has two structures, both ordinary and sealed. Ordinary type adjustment door only plays an adjustment role, must be isolated with other types of door interpurpose, sealed type adjustment door is with adjustment function, but also has the isolation function. For small capacity units can eliminate the ability to close the door or cut off the door. Sealed type adjustment door blades on both sides and the inside of the frame of the two sides of the shaft are pressed with stainless steel seal, when the blade closed with the steel pipe and the frame side closely attached, that is, to ensure the sealing effect, but also can absorb the blade heat generated by the thermal expansion. The adjustment door bearing uses self-lubricating center-shaped spherical bearings, which absorb the flexing reaction force caused by the pressure of the blades, thus ensuring that the door turns flexibly and does not get stuck.

Specification

Main technical parameters of the flap: Maximum operating pressure: 2000mmH2O

Maximum operating temperature: 420O

Operating condition: cold, hot air or flue gas

Sealed air pressure: 50mmH2O above the media pressure in the system: 0 to 90 degrees full clearance leakage rate: 1 % (sealed structure)

Application

The plug-in electric isolation door is suitable for the occasions where the boiler cold, hot air duct or flue duct needs to be shut off and isolated. For example: the coal mill inlet air duct is used to block the hot air entering the coal mill. It is developed in combination with foreign advanced technology research and development. It uses the linkage of the opening and closing electric device and the locking electric device to isolate the working medium. The product can be used for work, flexible opening and closing, and tight sealing. It is an important auxiliary equipment supporting equipment in the boiler system of a thermal power plant.
