Description

Smoke white eliminating device

Technical Field

The utility model relates to an environmental protection processing technology field especially relates to a flue gas white eliminating device.

Background

The "white smoke rolling" scene is unrelated to landscape and is strong evidence of serious pollution, and white smoke is not only a visual pollution effect for us.

About 5-10 years ago, much smoke is discharged, but haze is little; through years of treatment, the existing black smoke and yellow smoke are less, the haze is more, and the white smoke mainly based on wet desulphurization is common. White smoke discharged from a chimney is mixed with cold air in the environment, and in the process of cooling, contained water vapor is saturated and condensed, condensed water mist drops refract and scatter light, so that smoke plumes are white or gray, and are called as wet smoke plumes and are commonly called as big white smoke.

The white smoke seen by people is 'dense smoke rolling' because the smoke has higher dust content and can not reach the emission standard; the other is that the emission reaches the standard, but the white smoke phenomenon occurs because the environmental temperature is lower than the dew point of the smoke temperature in winter.

When the water vapor in the smoke is in a supersaturated state, part of the water vapor is condensed and fogged to form atomized fine liquid drops, and the phenomenon of 'white smoke' can occur. Especially in winter, the white smoke phenomenon is not only aggravated, but also causes greater resource waste because water is also a resource. Therefore, the white smoke discharged by industry needs to be eliminated, namely: eliminating white smoke. The aim of white elimination is to remove fog drops in flue gas so as to meet the requirements of new regulations for atmospheric treatment.

The existing smoke whitening device is complex in structure, large in occupied size and free of improvement on the effect of smoke whitening.

CN 30913561U provides a hood-type flue gas whitening tower, which is characterized by comprising a liquid reaction mechanism layer, a cooling reaction mechanism layer, a steam whitening device layer and a demister layer from bottom to top, so as to achieve the multiple effects of eliminating white smoke from flue gas and recycling condensed water, wherein the steam whitening device layer is arranged to achieve the further whitening effect; liquid drops carried by unsaturated flue gas passing through the steam whitewashing layer are effectively removed through the demister layer, and the phenomenon that the flue gas at the outlet of the chimney carries rain is eliminated. The pipe grid gas flow effect enhancer and the hood type liquid collector are installed at the same time, the pipe grid gas flow effect enhancer greatly improves the gas flow uniform distribution and gas-liquid two-phase mass transfer effects, unsaturated flue gas is saturated at an accelerated speed when passing through a lower slurry spraying device, and condensed water is separated out at an accelerated speed when saturated flue gas passes through the lower slurry spraying device; the hood type liquid collector adopts a combined structure of the sealing plate and the wind hood of the wind barrel, so that saturated flue gas can freely go upwards, upper cooling circulating liquid can be effectively intercepted, the mixing with slurry sprayed at the lower part is avoided, the flue gas resistance can be effectively reduced, the energy is saved, and the consumption is reduced.

However, in this application: 1. the spraying unit is positioned above the liquid reaction mechanism layer and sprays gas entering the tower body, and the gas is floated into the cooling reaction mechanism layer without fully contacting with the spraying solution, so that the utilization rate of the spraying solution is reduced; 2. the liquid sprayed in the liquid reaction mechanism layer and the cooling reaction mechanism layer cannot smoothly and completely flow out of the tank body, and the sprayed liquid cannot be completely pumped back for reuse even if a water pump is added, so that the liquid is easily discharged incompletely and completely deposited in the tank body, and the liquid is easily odorized; 3. the blast pipe setting of this application is in defroster layer top, makes gas be the circulation state, has reduced gaseous dwell time in the tower body, makes gaseous unable fully reaction just fly away to the tower body outside.
