Description

(54) ЦИКЛОННАЯ ТОПКА(54) CYCLONE HEAT

Изобретение относитс к топочным устройствам , предназначенным дл сжигани токсичных газов.This invention relates to combustion devices for burning toxic gases.

Известна циклонна топка, содержаща цилиндрический корпус с подвод щими патрубками токсичных газов и воздуха, топливоподающим устройством и окном дл отвода -продуктов сгорани , расположенными на противоположных торцах корпуса, а та«же установленную в полости последнего с образованием периферийного зазора цилиндрическую .вставку, |Выполнен«ую из равномерно . размещенных По окружности продольных пластин, образующих сужающиес к ООН вставки тангенциальные каналы 1.A known cyclone furnace containing a cylindrical body with inlet pipes of toxic gases and air, a fuel supply device and a window for discharging combustion products located at opposite ends of the body, and the same cylindrical insert installed in the cavity with the formation of a peripheral gap, | Completed “Go out evenly. Placed along the circumference of the longitudinal plates forming tangential channels tapering to the UN 1.

Недостатком данной топки вл етс Низка эффективность сжигани токсичных газов вследствие плохого перемешивани их с .воздухом и продуктаМИ сгорани .The disadvantage of this furnace is the low combustion efficiency of toxic gases due to their poor mixing with air and combustion products.

Цель изобретени - повыщение эффективности сжигани токсичных газов.The purpose of the invention is to increase the combustion efficiency of toxic gases.

Это достигаетс тем, что вставка выполнена из четного количества .пластин, а периферийный зазор разделен дополнительной кольцевой поперечной перегородкой на автономные отсеки, подключенные соответственно к патрубкам токсичных газов и воздуха, причем входные участки тангенциальных каналов вставки в каждом отсеке через один и с чередованием по отнощению к участкам каналов, расположенным в другом отсеке, заглушены.This is achieved by the fact that the insert is made of an even number of plates, and the peripheral gap is divided by an additional annular transverse partition into autonomous compartments connected respectively to the nozzles of toxic gases and air, with the input sections of the tangential channels of the insert in each compartment through one and alternating in relation to each other. to the sections of channels located in a different compartment are plugged.

На фиг. 1 .изображена предложенна 5 топка, общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б «а фиг. 1; на фиг. 4 - часть вставки в аксонометрии; «а ф-иг. 5 - вид В на фиг. 4.FIG. 1. Pictured is the proposed 5 firebox, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section BB “and FIG. one; in fig. 4 - part of the insert in axonometry; “A f-ig. 5 is a view of B in FIG. four.

Циклонна топка содержит цилиндрический корпус 1 с подвод щими патрубками 2 и 3 токсичных газов и воздуха, топливоподающим устройством 4 и окном 5 дл отвода продуктов сгорани , расположенным в противоположных торцах корпуса 1, IB полости которого установлена с образованием периферийного зазора 6 цил .индрическа вставка 7, выполненна из четного количества .равномерно размещенных по окружности продольных пластин 8,The cyclone furnace contains a cylindrical body 1 with inlet nozzles 2 and 3 of toxic gases and air, a fuel supply device 4 and a window 5 for removal of combustion products located in the opposite ends of the body 1, whose cavity IB is installed with the formation of a peripheral gap 6 cyl. , made of an even number. evenly spaced around the circumference of the longitudinal plates 8,

20 образующих сужающиес к оси вставки 7 тангенциальные каналы 9 и liO. The 20 tangential channels 9 and liO, which taper to the axis of the insert 7, form.

Периферийный зазор б разделен на автономные отсеки 11 и 12 дополнительной кольцевой поперечной перегородкой 13. Отсек 11 подключен к патрубку 2 подвода токсичных газов, а отсек 12 - « -патрубку 3 подвода воздуха. В отсеке 11 заглушены пластинами 14 входные участки каналов 9, а в отсеке 12 - пластинами 15 входныеThe peripheral gap b is divided into autonomous compartments 11 and 12 with an additional annular transverse partition 13. Compartment 11 is connected to the nozzle 2 for supplying toxic gases, and compartment 12 is “-pipe 3 for the air supply. In compartment 11, plates 14 are plugged with inlet portions of channels 9, and in compartment 12, plates 15 are input

Claims

30 sections of channels 10. The cyclone furnace works as follows. The gaseous fuel through the fuel supply device 4 enters into the interior of the insert 7, where it burns in a swirling flow of air and toxic gases, respectively coming from compartment 11 through channels 9 and compartment 12 through channels 10. Air flows iH of toxic gases enter inside insert 7 its length in the form of alternating thin flat jets. This alternation of air jets and toxic gases ensures a good displacement of all three components of combustion (air, toxic gas and fuel), which ensures fast and efficient burning. Claims of the invention A cyclone furnace containing a cylindrical body with inlet nozzles of toxic gases and air, a fuel supply device and a window for discharge of combustion products located on the anti-floor ends of the body, and a cylindrical insert installed in the cavity of the latter with a peripheral gap, made of uniform placed around the circumference of the longitudinal plates, forming tangential channels narrowing to the axis of the insert, which, in order to increase the efficiency with needing toxic gases by improving the mixture formation, the insert is made of an even number of plates, and the peripheral gap is divided by an additional annular transverse transducer into autonomous compartments connected respectively to the nozzles of toxic gases and air, and the input sections of the tangential channels of the insert in each compartment are alternately and alternately with respect to the sections of the channel, located in a different compartment, are muffled.
