Abstract

The utility model relates to a novel wet flue gas desulfurization demister, which is characterized in that a plurality of corrugated boards (2) are arranged in line, and the utility model is positioned and assembled by a fixed part (1) of the corrugate boards. Wherein the edge with a plurality of round bosses of the corrugated boards can block, collect the drops of the smoke and form a flowing guide surface further at the inlet and the outlet of the demister media. The demister with corrugated board can block and collect the drops of the smoke effectively, thereby the equipment can run normally. With the compact structure, high separating efficiency, fast air speed, small resistance, strong corrosion resistance, and easy cleanness, the utility model is particularly suitable for the wet flue gas desulfurizaiton demisting system in large industrial coal boiler.

Description

Novel wet flue gas desulfurization demister

Technical field

The utility model relates to a kind of large-scale demister of corrugated board structures form.

Prior art

Being used for capturing and remove the demister of the liquid phase droplet that gas phase carries secretly, is process equipment important in the large coal-fired boiler flue gas desulphurization system.Use the good demister of structure, purify the adverse effect that the entrained drop in back produces subsequent device operation with reducing flue gas desulfurization effectively, thereby guarantee that process units normally moves.

At present, the domestic large-scale wet-type flue gas desulfurization demister that has now put into operation is made of homogeneous plane wave card, because described structure can not stop the drop in the flue gas and capture fully, brings hidden danger for the normal operation of production equipment.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of demist better effects if, operation more reliable, and the demister of the low corrugated board structures form of cost.

The technical solution adopted in the utility model is such: promptly demister is arranged by some corrugated platings, and constitute by the location assembling of corrugated plating fixture, wherein: the edge that corrugated plating has round boss is positioned at demister medium inlet and exit, constitutes blocking surface, collection face and guide face to the flue gas drop.

The utility model constitutes flue gas drop blocking surface, collection face and water conservancy diversion in the medium inlet and the exit of demister owing to adopt corrugated plating, and the drop in the flue gas can effectively be stopped and capture, thus the normal operation of the equipment of assurance.

The height of the width decision demister of described corrugated plating, its distance between plates is from determining as calculated according to the requirement of its applied environment and demist.

The mechanism of the utility model demister demist is to have utilized the operation principle of inertial collision in the gas-liquid two-phase separation.The demister of the homogeneous plane wave card formation that extensively adopts relatively at present, the inlet exit has the demister of the corrugated plating formation of round boss, in the demist process, when most of droplet is subjected to surface tension effects, with adhere to the corrugated plating surface after the corrugated plating collision and constantly form large-area liquid film, be subjected to the gravity effect of liquid film own, liquid stream moves downward to corrugated plating edge along the corrugated plating surface, will after forming big drop, short transition settle down along the arc surface of corrugated plating edge projection, directly fall thereby reduced the small particle diameter drop, easily form the phenomenon that reentrainment reduces separative efficiency.This round boss slyness is bright and clean, can reduce to adhere to the trend that gas passage is reduced because of impurity.

The demister that is provided by the utility model has that resistance is little, demist efficient height, not dust stratification, do not stop up, characteristic such as less scaling, and low cost of manufacture can satisfy the needs that China's industry coal-boiler is built desulfurizer.

The specific embodiment

With reference to accompanying drawing, wet flue gas desulfurization demister among the figure comprises the some corrugated platings 2 that begin just to have a round boss from edge, the plate of this corrugated plating is wide between 150～250mm, distance between plates is between 25～40mm, formation that described corrugated plating equidistant parallel is arranged and fixture 1 is assembled together.Corrugated plating fixture 1 is a surface plate, has embedding groove consistent with the ripple of corrugated plating 2, the spacing unanimity thereon, and corrugated plating 2 is assemblied in the embedding groove of fixture 1 and constitutes box demister.If single case demister corrugated plating length is when being lower than 1.2m, single case demister needs two fixtures assemblings to finish, if single case demister corrugated plating length during greater than 1.2m, can be set up fixture in the middle of its corrugated plating.

The utility model demister has compact conformation, separative efficiency height, allows big, the characteristics such as resistance is little, corrosion resistance is strong, easy cleaning of gas speed, is specially adapted to large scale industry coal-burning boiler wet flue gas desulfurization demister system.

Claims

1, a kind of novel wet flue gas desulfurization demister, it is characterized in that: arrange by some corrugated platings (2), and by corrugated plating fixture (1) location assembling formation, wherein: the edge that corrugated plating has round boss is positioned at demister medium inlet and exit, constitutes blocking surface, collection face and guide face to the flue gas drop.

2, novel wet flue gas desulfurization demister according to claim 1 is characterized in that: corrugated plating (2) equidistant parallel is arranged; Corrugated plating fixture (1) is a surface plate, has embedding groove consistent with the ripple of corrugated plating (2), the spacing unanimity thereon, in the embedding groove that is assemblied in fixture (1) of corrugated plating (2).
