Abstract
The present invention discloses the improvement of the technical scheme of a seawater smoke washer, which comprises the following steps that the seawater is sent to the smoke washer to spray the smoke passing through the smoke washer, so acidic gas in the smoke is washed; the purified smoke is sent from a smoke outlet; the washed seawater is output from a seawater outlet pipeline, etc. The smoke washer which is arranged vertically is changed to be arranged horizontally. The present invention has the advantages that the energy consumption and the operation cost of the smoke purifying process system with a seawater method are reduced greatly, and the original operation performance and the original purification effect of the system are kept simultaneously.
Description
The present invention relates to a kind of sea water flue gas washer, belong to environmental protection technical field, is a kind of improvement technical scheme that is applicable to coastal industry device full sea water method flue gas purifying technique washer.
In order to protect environment, prevent and treat acid rain, the flue gas that industrial burning device produced must remove wherein a part or most of SO before entering atmosphere
2Deng sour gas.Some remove SO in the flue gas
2Method, the cost that relates to is high and operating cost that factors such as absorbent and byproduct cause is very high, often forms the contradiction of environmental benefit and economic benefit and is difficult to use.At present, existing a kind of seawer washing flue gas that utilizes in the coastal area is to remove SO in the flue gas
2Method, its gas cleaning effect is better, the cost and the operating cost of process facility are low, do not have accessory substance to produce, its draining meets China's marine environment water standard, and is safe and harmless to the marine eco-environment.This method is sent to the flue gas washing tower top of setting up to tens of meters with the spray washing acidic gas in flue gas with seawater, the more acid seawater after the washing is carried out water treatment, discharges after making it reach environmental quality requirement.But, the seawater that this method is used to wash need promote tens of meters elevations, although this technology taked only to promote a part of seawater again with the measure of other seawater blending to reduce energy consumption, because total water yield is very big, its operating cost is still higher, thereby the use of this technology is limited to.
Purpose of the present invention is to overcome the above-mentioned shortcoming that existing sea water flue gas process for purifying washer exists, and provides a kind of improvement technical scheme of sea water flue gas washer, with the energy consumption of further reduction seawater method flue gas purifying technique.
The improvement technical scheme that realizes the object of the invention is: it comprises that the washing seawater that seawater is sent to the smoke washer spray enters pipe, gas approach, the flue gas after being purified outlet, seawater outlet pipe after the washing and smoke washer body, the smoke washer body is the horizontal direction setting, its length l is l: h=0.5～10 with the ratio of height h, to reduce the lifting elevation of washing with seawater significantly.
Further technical solution of the present invention is described as follows below in conjunction with drawings and Examples.
Fig. 1 is a prior art flue gas washing tower structure schematic diagram.
Fig. 2 is the embodiment of the invention two smoke washer structural representations.
Fig. 3 is the embodiment of the invention three smoke washer structural representations.
Fig. 4 is the embodiment of the invention four smoke washer structural representations.
Name is called shown in the figure: 1, smoke washer, 2, gas approach, 3, exhanst gas outlet, 4, the washing seawater enters pipe, 5, the seawater discharge pipe, 6, smoke washer length 1,7, smoke washer inner facility, 8, smoke washer height h.
The principle of technical solution of the present invention is: reduce smoke washer height h, increase the smoke washer length l, the time and intensity of flue gas washing is remained unchanged, kept original detersive efficiency like this, reduced the lifting elevation of cleaning solution simultaneously, the also corresponding reduction of its power consumption.Be mainly the power consumption that seawater promotes because the operating cost of seawater method flue gas purifying technique constitutes, therefore improvement technical scheme of the present invention energy efficient significantly reduces the operating cost of flue gas purifying technique system significantly.
Smoke washer inner facility (7) can be for strengthening filler, the sieve plate that the exchange effect is provided with, and also can be hollow.
To enumerate embodiment as follows in order to further specify technical scheme of the present invention and effect:
Embodiment one: the ratio l of the length l of smoke washer and height h: h=0.5;
Embodiment two: the ratio l of the length l of smoke washer and height h: h=1.8;
Embodiment three: the ratio l of the length l of smoke washer and height h: h=3;
Embodiment four: the ratio l of the length l of smoke washer and height h: h=5;
Embodiment five: the ratio l of the length l of smoke washer and height h: h=8;
Embodiment six: the ratio l of the length l of smoke washer and height h: h=10.
The invention has the advantages that, decrease energy consumption and the fortune of seawater method flue gas purifying technique system Row expense, the simultaneously original runnability of keeping system and clean-up effect.
