In order to solve above-mentioned problems, we adopt to set up a dense section of cooling condensation for dust removal before entering the absorbing process of the main tower. This process adopts turbulent shock technology to implement the cooling and ammonium sulfate concentration process, and the water washing operation to dust and other impurities, and then filter the impurities in the serous fluid. It may effectively remove more than 80% of the dust and impurities. As for the oversaturation flue gas with high moisture content, this process also has the function of water elimination. The impurities such as dust in the flue gas are removed in this process, so the impurities in the ammonium sulfite absorbed in the circulation serous fluid is very few in the subsequent filtration module area and demister. It guaranteed that the demister does not have the occurrence of block, and reduced the production of the ammonium sulfate aerosol, which improves the utilization ratio of the ammonia and reduces the secondary pollution.
（2）效率高，能同時進行除塵和脫硫
(2) With high efficiency, and can carry on the dust removal and desulphurization process at the same time
湍沖洗滌以不霧化的噴頭將液相物料湍沖狀噴射與逆向運動的氣流進行撞擊，在某一設(shè)定區(qū)域建立能量、質(zhì)量、熱量的動態(tài)交換場。在這交換場由于液相是湍沖狀態(tài)，并不斷切割氣相使之也形成湍沖狀，達到二相的表面積不斷更新，取得最大的比表面積，而充分交換。
The turbulent scrubber sprays the liquid phase materials in turbulent form by non-atomized nozzle, and impacts with the reverse air current. Establish the dynamic exchange field of energy, quality and heat in certain area. As the liquid phase is the turbulent form in this field, and it may constantly cut the air phrase and make it transform to the turbulent form. The surface area of two phases is constantly renewed, so as to achieve the largest surface area and realized the full exchange.
由于是不霧化噴頭，噴口直徑大，吸收原理先進，解決了傳統(tǒng)濕法吸收過程中噴嘴堵塞的問題，還大大地降低了噴頭的操作壓力。它不但脫硫的效率極高，單級的湍沖處理脫硫效果可達95%以上，而且除塵效率亦極高。
As for the application of non-atomized nozzle with large nozzle diameter and advance absorbing principle, it has solved the problem that the spray nozzle may easily block in the traditional wet absorbing process, and greatly reduced the operation pressure of the nozzle. It not only has the high efficiency in desulphurization process, and the desulphurization result of single grade may reach to 95% above, but also has extremely high efficiency in dust removal.
另外，湍沖洗滌過程氣相物質(zhì)必須經(jīng)過液相的湍沖狀交換場，故氣量變化時僅是使動態(tài)交換場位置移動而對脫除效率影響很少，工業(yè)化過程中，氣相量的變化極為正常，湍沖洗滌應(yīng)對此情況有著顯著的適應(yīng)性，系統(tǒng)內(nèi)氣量變化50%左右情況下，二氧化硫脫除率基本不變。
In addition, the air phrase materials in the turbulent scrubbing process shall pass through the turbulent exchanging field. Therefore, the position movement of dynamic exchanging field may result limited influence in removal efficiency in the changing of gas content. In industrialization process, the changing of gas content is quite normal. The turbulent scrubbing shall have the remarkable adaptability to this situation. When the changing of gas content in the system is 50%, the removal rate of sulfur dioxide does not change.
（3）低投資、吸收劑適應(yīng)性寬
(3) Low investment, wide adaptability of absorbent
傳統(tǒng)濕法的脫硫除塵氣體處理裝置一般體積較大、結(jié)構(gòu)復(fù)雜，它與高溫腐蝕性氣體直接接觸的表面積大，對于這種設(shè)備的防腐措施受到目前制造加工工藝的限制，往往只能采用昂貴的材料制成整體設(shè)備，造成了高額投資，難以在環(huán)保領(lǐng)域內(nèi)廣泛應(yīng)用。
he traditional wet desulphurization of dust and gas removal device is always characterized in large volume and complicated structure, which has large surface area directly contacted with high-temperature corrosive gas. The antiseptic measures of these equipments are restricted by the processing technology at present. Usually, it can only adopt the expensive materials to build the integral equipment, which may cause the large investment and shall be difficult to implement the extensive application in the environmental protection field.
本除塵脫硫裝置工藝包整體設(shè)計有針對性地、有效地解決了上述問題。它采用不同防腐材料、不同防腐工藝、分區(qū)域進行防腐。將高溫強腐蝕惡劣工況集中在幾何形腔較簡單、體積較小的圓筒形洗滌器上端部的小區(qū)域內(nèi)，即在該區(qū)域?qū)Ω邷責煔膺M行脫硫的處理，故只需要在該小區(qū)域內(nèi)采用適應(yīng)的重點防腐措施。
The design of this dust removal desulphurization device has effectively solved above-mentioned problems. It adopts different antiseptic materials, different antiseptic processes, and may assign antiseptic process in divided field. It may concentrate the serious operating mode of the high temperature and corrosive environment in the simple shape of geometry in the small area of the top part of small cylindrical scrubbing device. Namely, it may carry on the treatment of the desulphurization to the high-temperature flue gas in this area, therefore, it only need to adopt the key antiseptic measure in this small area.
如處理高溫氣體時，以耐高溫的聚四氟乙烯或石墨材料制作形腔簡單，而且體積相對小的溢流堰。通過該溢流堰形成降膜，隔離高溫強腐蝕介質(zhì)與圓筒形洗滌器主體設(shè)備直接接觸。又如遇處理特殊的腐蝕惡劣氣體，像含高氟、氯等的高溫氣體，也只需在液、氣交界面的小區(qū)域以緊襯聚四氟乙烯接管進行防腐處理，即可保證防腐襯里層長期可靠運行。
