Однако данные устройства сложны и неэффективны с точки зрения степени очистки газа.However, these devices are complex and inefficient in terms of the degree of gas purification.

Наиболее близким к изобретению по технической сущности и достигаемому результату является пробоотборник загрязненного газа, содержащий'газозаборную трубу, соединенную с трубопроводом загрязненного газа, и охладитель конденса2 тор, соединенный с источником хладоагента [2]. 'The closest to the invention in terms of technical nature and the achieved result is a contaminated gas sampler containing a gas intake pipe connected to a contaminated gas pipeline and a condenser cooler connected to a refrigerant source [2]. ''

Недостатком устройства является сложность его конструкции и малая эффективность охлаждения и очистки газа от загрязнений.The disadvantage of this device is the complexity of its design and low efficiency of cooling and gas purification from pollution.

Целью изобретения является упрощение конструкции пробоотборника и повышение эффективности охлаждения и очистки газа от загрязнений.The aim of the invention is to simplify the design of the sampler and increase the efficiency of cooling and gas purification from contamination.

Эта цель достигается тем, что охладитель-конденсатор выполнен в виде тангенциального патрубка, соединенного с верхним концом газозаборной трубы, нижний конец которой снабжен газоотделителем, причем отношение длины заборной трубы к ее диаметру ( I / cL ) находится в пределах от 5 до 1О.This goal is achieved in that the cooler-condenser is made in the form of a tangential pipe connected to the upper end of the gas intake pipe, the lower end of which is equipped with a gas separator, and the ratio of the length of the intake pipe to its diameter (I / cL) is in the range from 5 to 1O.

На фиг. 1 изображено устройство, продольный разрез; на фиг. 2 - сечение А-А на фиг. 1.In FIG. 1 shows a device, a longitudinal section; in FIG. 2 is a section AA in FIG. 1.

Пробоотборник состоит из заборной трубы 1, верхняя часть которой соединена с каналом 2 подвода хладоагента от источника 3, а также через открытый торен 4 с трубопроводом 5 загрязненноΙΌ газа, идущего из системы улавливания технического углерода к установкам для дожигания. Нижний торец 6 заборной трубы 1 связан с гаэоотделителем 7, в котором имеется отверстие для ввода очищенного газа и магистраль 8 для слива конденсата в линию слива.The sampler consists of an intake pipe 1, the upper part of which is connected to the channel 2 for supplying refrigerant from source 3, as well as through an open torne 4 with a pipeline 5 of contaminated gas coming from the carbon black recovery system to the afterburner. The bottom end 6 of the intake pipe 1 is connected to a gas separator 7, in which there is an opening for introducing purified gas and a line 8 for draining the condensate into the drain line.

Пробоотборник работает следующим образом.The sampler works as follows.

При подаче в трубу 1 через канал 2 от источника 3 подается хладоагент (вода). В результате тангенциального ввода жидкость, введенная по периферии, начинает вращательное движение с одновременным перемещением вниз, в результате чего внутри трубы 1 в центральной части образуется пространство, свободное от воды, в которую начинается подсос загрязненного газа через торец 4 из трубопровода 5. Захваченная часть газа перемещается вдоль вращающегося потока воды, охлаждаясь и одновременно частично очищаясь от частиц технического углерода.When feeding into the pipe 1 through the channel 2 from the source 3 is supplied refrigerant (water). As a result of tangential injection, the fluid introduced along the periphery begins to rotate with simultaneous movement downward, as a result of which inside the pipe 1 in the central part there is formed a space free of water, into which the contaminated gas is sucked in via end 4 from pipeline 5. Captured part of the gas moves along a rotating stream of water, cooling and at the same time partially purifying from carbon black particles.

У нижнего торна 6 трубы 1 газы, будучи уже охлажденными, разворачиваются и, проходя через вращающуюся конусную пленку хладоагента, окончательно· очищаются от загрязнений. Загрязненная вода собирается в данной части газоотделителя 7 и через магистраль 8 сбрасы5At the lower thorn 6 of pipe 1, the gases, being already cooled, unfold and, passing through a rotating conical film of refrigerant, are finally · cleaned of contaminants. Contaminated water is collected in this part of the gas separator 7 and discharges through line 8

Claims

The invention relates to devices for collecting liquid or gaseous media, and in particular, to devices for removing gas from filters for trapping technical carbon (soot). A device for sampling contaminated gases, in which hot gas is extracted by means of an intake pipe, is introduced into. sealed, whether cooled-condensers, where by indirect heat exchange through a metal wall the gas is cooled to an acceptable temperature; The gas is then purified from and conveyed to a device for analyzing its composition ij. However, these devices are complex and inefficient in terms of the degree of gas purification. Closest to the invention by its technical essence and the achieved result is a contaminated gas sampler containing a gas sampling pipe connected to the pipeline of polluted gas, and a cooler condenser connected to a source of refrigerant. The drawback of the device is the complexity of its design and the low efficiency of gas cooling and gas cleaning. The aim of the invention is to simplify the instructions of the sampler and increase the efficiency of cooling and gas cleaning from contamination. This goal is achieved by the fact that the cooler-condenser is made in the form of a Tac-Genial nozzle connected to the upper end of the gas intake pipe, the lower end of which is equipped with a gas separator, and the ratio of the length of the intake pipe to its diameter 1O. FIG. 1 shows a device, a longitudinal section; in fig. 2 is a section A-A in FIG. 1. The sampler consists of the intake pipe 1, the upper part of which is connected to the coolant supply channel 2 from the source 3, as well as through the open end 4 to the pipeline 5 of contaminated gas coming from the carbon black trapping system to the afterburner. The bottom end 6 of the intake pipe 1 is connected to a gas separator 7, in which there is an opening for introducing clean gas and a line 8 for draining condensate into the drain line. The sampler works as follows. When fed to pipe 1 through channel 2 from source 3, refrigerant (water) is supplied. As a result of a tangential inlet and liquid introduced along the periphery, a rotational movement starts with a simultaneous downward movement, as a result of which inside the pipe 1 in the central part a space free of water is loaded, into which polluted gas begins to suck through the end 4 of pipeline 5 The trapped portion of the gas moves along the rotating stream of water, cooling and at the same time partially purifying from carbon particles. At the lower torp 6 of the pipe 1, the gases, being already cooled, unfold and the passage through the rotating conical film of the refrigerant is finally cleared of contaminants. The polluted water is collected in this part of the gas outlet 7 and through the main line 8 of the discharge 7 24 to the sewage system. In order to eliminate the discharge of water from the intake pipe 1 into the gas pipeline 5, the refrigerant / P gas condition P must be maintained, which can be ensured by adjusting the pressure in the tangential channel 2.
