Abstract
The invention discloses a device and method for modulating liquid phase resonance water attack of auto-excitation type deduster. The device is arranged between an orifice and a contact chamber, and is composed of a set of baffle plates, the structure composed of the baffle plates is arranged under the liquid surface in a water storage box and is capable of absorbing the waving energy of the liquid surface; the baffle plates are criss-crossly arranged, each baffle plate is vertical to the liquid surface, and the vertical baffle plates that is perpendicular to the flowing direction of the dedusting air flows are provided with energy dissipating holes. When a deduster is operated, a large amount of liquid is brought into the rear part of a water storage tank by the air flows, thus a large liquid level difference is formed between the rear part and front part of a dedusting cavity, at the same time, a resonance water attack phenomenon is generated; the baffle plates can inhibit the large fluctuation of liquid surface in the vertical and horizontal directions so as to eliminate the resonance water attack phenomenon; at the same time, the baffle plates are provided with a certain porosity, so dedusting liquid can flow back and forth in the water storage box, and the dedusting liquid in the front part of the water storage box can be supplemented in time; and the device can maximally reduce dust escape due to the large fluctuation of liquid surface, improves the comprehensive dedusting efficiency of auto-excitation type deduster, and eliminates the hazards that the equipment is damaged by resonance water attack.
Description
Technical field
The present invention relates in a kind of self-induced scrubber course of work, for regulating and controlling device and the side of its liquid phase resonance water attack
Method, specially a kind of apparatus and method of regulation and control self-induced scrubber liquid phase resonance water attack.
Background technology
Self-induced scrubber simple structure, easy to maintenance, cost are relatively low, are the maximum discharge rows such as mining industry, metallurgical and Coal Chemical Industry
The conventional environmental protection equipment that industry fine particle is reduced discharging, and obtain a wide range of applications.But find in practical application, auto-excitation type is removed
In the dirt device course of work, in certain flow rates, due to its liquid level intrinsic frequency and air-flow by when Pneumatic immpacting
Frequency is close to（Or be close to the integral multiple of Pneumatic immpacting frequency）, covibration is thus resulted in, makes to produce at the restriction of deduster
The strong resonance water hammer of life.
When water attack occurs, the liquid level in deduster produces fluctuation phenomenon back and forth, causes the liquid level at restriction to neglect
It is high suddenly low.When liquid level is in a high position, liquid phase blocking flow channels make air-flow pass through；When liquid level is in low level, crosses and circulate
Road is larger, and dust-contained airflow passes through ullage is smooth（Dust is caused to escape）, cause trapping of the deduster to dust to be failed, shadow
Deduster combined dust-eliminating efficiency is rung.Meanwhile, resonance water attack also threatens deduster structure safety to a certain extent.
