Description

Изобретение относитс  к устройствам, дл  получени  контролируемых атмосфер, примен емых , например, в металлургии и машиностроении . Известен эндо-экзогенератор, состо щий из герметизированной футерованной камеры сжигани  с вод ной рубашкой, лотком с катализатором , ретортой, выполненной с тороидальным поперечным сечением горелок, и устройства дл  регулировани , включающего автоматическую задвижку на трубопроводе экзогаза, выход щего КЗ камеры сжигани . Цель изобретени  - расширение пределов регулировани  температуры процесса и получение более стабильного состава эндотермической и экзотермической контролируемых атмосфер. Дл  этого в предлагаемом эндо-экзогенераторе трубопровод экзогаза, покидающего камеру сжигани , соедин ют с горелками коллектором с холодильным устройством и задвижкой, регулирующей расход охлажденной экзотермической контролируемой атмосферы, возвращающейс  в камеру сжигани . На чертеже показан предлагаемый эндоэкзогеиератор . Он состоит из герметизированной футерованной камеры 1 сжигани  с горелкой 2, вод ной рубашкой 3 и лотком 4 с катализатором , реторты 5 с катализатором и термопарой 6, размещениой в слое катализатора, автоматической задвижки 7с импульсной линией 8 от термопары дроссел  9, коллектора 10, холодильного устройства 11 и задвижки 12. Эндо-экзогенератор работает следующим образом. В камеру 1 сжигани  через горелку 2 подаетс  газовоздушна  смесь с коэффициентом расхода воздуха ниже (напрнмер, а-0,95). Камера сжигани  снаружи охлаждаетс  водой , подающейс  в водочную рубашку 3 дл  получеии  наибольшей полноты сгорани  топлива , на выходе продуктов сгорани  из камеры сжигани  установлен лоток 4 с катализатором . Продукты сгорани  иа выходе из камеры сжигани  представл ют собой экзотермическую контролируемую атмосферу. Газовоздушна  смесь дл  получени  эндотермической контролируемой атмосферы подаетс  в кольцевое сечение реторты. 5, где находитс  катализатор. В реторте при температуре пор дка 1000-1100° С происходит процесс приготовлени  эндогаза. Регулирование процесса получени  двух коитролируемых атмосфер осуществл етс  по температуре в слое катализатора термопарой 6. Регулирование температуры осуществл етс  следующим образом.The invention relates to devices for producing controlled atmospheres used, for example, in metallurgy and mechanical engineering. An endo-exogenerator is known, consisting of a sealed lined combustion chamber with a water jacket, a tray with a catalyst, a retort made with a toroidal cross-section of the burners, and a control device, including an automatic valve on the exogas pipe, which leads to a short-circuit combustion chamber. The purpose of the invention is to expand the range of temperature control of the process and obtain a more stable composition of endothermic and exothermic controlled atmospheres. For this, in the proposed endo-exogenerator, the exogas pipe leaving the combustion chamber is connected to the burners with a collector with a refrigeration device and a valve controlling the flow of the cooled exothermic controlled atmosphere returning to the combustion chamber. The drawing shows the proposed endoexogeerator. It consists of a sealed lined combustion chamber 1 with a burner 2, a water jacket 3 and a tray 4 with a catalyst, a retort 5 with a catalyst and a thermocouple 6, placed in a catalyst bed, an automatic valve 7c with a pulse line 8 from a Drossel thermocouple 9, collector 10, refrigeration the device 11 and the valve 12. The endo-exogenerator works as follows. Through the burner 2, the combustion chamber 1 is supplied with a gas-air mixture with a lower air flow rate (eg, a-0.95). The combustion chamber is cooled outside by water supplied to the vodka jacket 3 to obtain the most complete combustion of fuel, and at the outlet of the combustion products from the combustion chamber tray 4 with a catalyst is installed. Combustion products leaving the combustion chamber are exothermic controlled atmosphere. The gas-air mixture to obtain an endothermic controlled atmosphere is fed to the annular section of the retort. 5 where the catalyst is located. In the retort, at a temperature of about 1000-1100 ° C, the process of endogas preparation takes place. The regulation of the process of obtaining two co-controlled atmospheres is carried out according to the temperature in the catalyst bed by a thermocouple 6. The temperature control is carried out as follows.
