Method of scrubbing and device for removal of sulfur oxides from combustion products

FIELD: cleaning of effluent flue gases from sulfur oxides, particularly, methods and devices for washing of sulfur oxides (SO x ) out of effluent flue gases with aqueous limestone slimes. SUBSTANCE: in single-pass open tower-type counterflow scrubbers for limestone wet scrubbing of gases, discharge velocity of effluent flow is considerably increased, while value of liquid/gas ratio and treatment time in reaction vessel are reduced. Specified above merits arise from use of entrainment separator of improved design, nature of sprayers arrangement and interval between time and also from application of hydrocyclone for separation of gypsum formed as byproduct, and return of finer particles of limestone back to process. Limestone is ground to highly dispersed particles, for instance, sizing approximately 8 mcm or less with more than 99 wt.% of particles sizing less than 44 mcm; and obtained product is added to slime for gas scrubbing which is brought in contact with effluent flow containing SO x . Reactivity of slime for scrubbing of gases is maintained even at low pH values by continuous operation of hydrocyclone due to which value of molar ratio of calcium- and sulfur-containing substances is ensured high approximately 1.3:1, and simultaneously low content of chlorides and nonreactive commercial materials is maintained. Hydrocyclone removes large particles of calcium sulfate and provides for obtaining of recirculating flow of finely dispersed calcium carbonate and nonreactive solid material. The flow, if required, is washed to maintain needed low content of chlorides and nonreactive solid materials.

Simplified efficient process for reducing NOx, SOx, and particulates

The removal of SO x and particulates, and preferably also NO x , from the combustion gases of a large boiler, is simplified while efficiency is improved. In a primary treatment zone, a slurry comprising an alkaline SO x -reducing composition and preferably a nitrogen-containing composition effective to reduce NO x , is introduced into combustion gases at a temperature of from about 900° to about 1300° C. The gases are cooled by initial contact with steam-generating means, and then by contact with an gas-to-gas heat exchanger. Cooled gases are then subjected to a secondary treatment in which they are first humidified and further cooled by introduction of a water spray or aerosol to reduce the temperature to 100° C. or below. Contact between the SO x -reducing composition and the humidified gases is maintained for a reaction period of at least 2 seconds. Particulate solids are then separated from the gases with a fabric filter. The cleaned gases are reheated by the gas-to-gas heat exchanger prior to discharge to the atmosphere. Reductions of SO x of greater than 80% are achieved, preferably 90 to 95%.

Device removing nitrogen oxides in the exhaust gas

본 발명은 배기가스에 함유된 질소산화물 제거장치로 보일러나 발전기 등에 사용되는 연료 및 연료의 연소과정 중 연소 공기로 인해 생성된 질소산화물(NOx)을 함유한 배기가스를 가온하지 않고 약품과 반응시켜 질소산화물을 제거할 수 있도록 기존의 배출시설인 배기덕트에 NOx 제거시설을 간단하게 설치하여 사용하는 것을 특징으로 한다. The present invention is a nitrogen oxide removal device contained in the exhaust gas and reacts with the chemicals without heating the exhaust gas containing nitrogen oxides (NOx) generated by the combustion air during the combustion of the fuel and fuel used in boilers or generators, etc. It is characterized in that the NOx removal facility is simply installed and used in the exhaust duct which is an existing discharge facility to remove nitrogen oxides. 또한, NOx 제거시설 내로 이송되는 배기가스에 함유된 질소산화물을 제거하기 위한 약품 주입방법의 특화로 인해 타 공법보다 적은 약품을 사용하고도 2배 이상을 제거하는 효과는 물론 NOx 제거시설의 운전이 용이하기 때문에 별도의 인건비가 소요되지 않아 유지관리비가 거의 들지 않는 특징이 있다. In addition, due to the specialization of the chemical injection method to remove nitrogen oxides contained in the exhaust gas transported into the NOx removal facility, the operation of the NOx removal facility is reduced as well as the effect of removing more than twice as much chemicals as other methods. Because it is easy, there is no extra labor cost, so there is almost no maintenance cost. 배출시설, 히트 익스체인저(Heat Exchanger), NOx 제거시설, 후처리시설 Exhaust Facility, Heat Exchanger, NOx Removal Facility, After Treatment Facility

The present invention relates to a large circulating fluidized bed boiler, comprising: a furnace having a vertical furnace centerline; And at least two groups of cyclone separators each cyclone separator in the cyclone separator group having one inlet flue with the furnace wherein the cross section formed by the outer flume at the flue gas cyclone separator inlet flue portion comprises 2 x n Wherein n is an integer greater than 1; Wherein said polymorphism is axisymmetric about the vertical bisector of the sides of polymorphism; when n is 2, the polymorphism is square; The triangle formed by the intersection between the two end points on the cross section of the inlet of the cyclone separator inlet and the cross section of the furnace center line and the cross section is a joint triangle; Thereby forming a single flow field through both the median inlet and the cross-section.

Wet-type air cleaner and wet-type device for purifying exhaust gases, which use centrifugal impeller

Изобретение относится к аппаратам очистки мокрого типа, использующим центробежное рабочее колесо. Воздухоочиститель включает газовый всасывающий канал (405), бак для жидкости (401) и газожидкостный центробежный сепаратор (407), в котором центробежное рабочее колесо (408) вращает всасываемый воздух. В газожидкостном центробежном сепараторе (407) корпус и цилиндр прохода газа смонтированы так, что сформированный вихревой поток, в котором создается центробежная сила, может пройти определенное расстояние вдоль них. Газожидкостный центробежный сепаратор (407) имеет первую вихревую камеру и вторую вихревую камеру. Первая вихревая камера выполнена между корпусом и цилиндром прохода газа. Вторая вихревая камера выполнена в цилиндре прохода газа. Газовый всасывающий канал (405) смонтирован перед газожидкостным центробежным сепаратором (407) для прохода по нему воздуха. Бак для жидкости (401) сообщается с газовым всасывающим каналом (405) для подачи промывочной воды в газовый всасывающий канал (405) через распылитель жидкости (403). Загрязняющие вещества воздуха, поступающие через газовый всасывающий канал (405), собираются с использованием промывочной воды. Воздух очищается газожидкостным центробежным сепаратором за счет разницы удельного веса воздуха и промывочной воды. Техническим результатом является увеличение степени очистки. 2 н. и 14 з.п. ф-лы, 1 табл., 15 ил.

Control method of pulverised-coal boiler plant

FIELD: power industry. SUBSTANCE: invention relates to power industry. Prepared brown coal is used as fuel according to the control method of the pulverised-coal boiler plant. In the boiler plant, exit gas removed from an exit gas duct is added to air from a primary air fan for preparation of mixed gas with oxygen concentration of less than 12% in volumetric ratio; with that, mixed gas is separately supplied to a conveying gas duct that passes through a gas heater and a bypass duct for conveying gas, which bypasses the gas heater, and after that, mixed gas is supplied to the mill. EFFECT: invention allows safe use of prepared low-grade coal as fuel and requires inconsiderable modification of the existing pulverised-coal boiler plants. 4 cl, 3 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (51) МПК F23K 3/02 (13) 2 563 646 C2 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ (21)(22) Заявка: ИЗОБРЕТЕНИЯ К ПАТЕНТУ 2014105184/06, 12.07.2012 (24) Дата начала отсчета срока действия патента: 12.07.2012 (72) Автор(ы): ТАДА Тосия (JP) (73) Патентообладатель(и): КАБУСИКИ КАЙСЯ КОБЕ СЕЙКО СЕ (КОБЕ СТИЛ, ЛТД.)
