Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0013] Such as Figure 1 to Figure 2 As shown, a novel gasification vacuum flash tank demister includes a plurality of V-shaped baffles 1 arranged at intervals in sequence, and is characterized in that three through holes 2 are opened on the V-shaped baffles 1 .

[0014] The three through holes 2 are arranged on the same side of the V-shaped baffle 1 .

[0015] The three through holes 2 are evenly spaced.

[0016] When in use, the air in the flash tank passes through the space between two adjacent V-shaped baffles 1, most of the solid particles and liquid droplets are intercepted by the V-shaped grooves of the V-shaped baffles 1, and there are a few The part that passes through the through hole 2 and enters the adjacent V-shaped baffle 1 continues to be trapped. For each individual V-shaped baffle 1, since a small part of solid particles p...

Abstract

According to a novel defoamer for a gasification vacuum flash tank, three through holes are formed in each V-shaped baffle plate, so that when a mixture flows through flow channels among blades, the passing ability is better, blockage is not likely to happen, and meanwhile the separation effect of gas-phase components, solid particles and liquid drops is not affected. The normal negative pressureof the flash tank can be ensured, and the normal defoaming effect of flash steam can be achieved. The novel demister for a gasification vacuum flash tank comprises a plurality of V-shaped baffle plates which are sequentially arranged at intervals, and three through holes are formed in each V-shaped baffle plate; the three through holes are formed in the same side of each V-shaped baffle plate; andthe three through holes are uniformly formed at intervals.

Description

technical field [0001] The invention relates to the technical field of demisters, in particular to a novel gasification vacuum flash tank demister. Background technique [0002] The demister on the top of the vacuum flash tank adopts the baffle plate inertia demister, and its main function is to prevent the water and fly ash in the flash gas from entering the meteorological pipeline. [0003] The baffle inertia demister is an air foam separation device composed of a large number of parallel V-shaped baffles. The bend formed by the V-shaped baffles makes the flow direction of the airflow change sharply, and the gas phase components can pass through the spacious flow channel between the baffles smoothly, while the liquid phase and solid particles hit the V-shaped groove under the action of inertia, and the speed drops. It is zero, and then flows down into the sump along the blades and discharged, so that the purpose of separating solid particles and liquid droplets from the g...
