Description

Изобретение относитс  к нагревательным устройствам.This invention relates to heating devices.

В р де массовых процессов терхмообработки (например, сушка лакокрасочных покрытий , спекание электролюминисцентных индикаторов и др.) используютс  низкотемпературные электрические печи, содержащие замкнутую камеру дл  нагрева изделий.In a number of mass heat treatment processes (for example, drying paint coatings, sintering electroluminescent indicators, etc.), low-temperature electric furnaces containing a closed chamber for heating products are used.

В ходе технологического процесса из термообрабатываемых изделий или материалов выдел ютс  пары и газы, создающие с атмосферным воздухом взрывоопасные смеси.During the process, vapors and gases are released from the heat-treated products or materials, creating explosive mixtures with atmospheric air.

В низкотемпературных печах, когда температура внутри нагревательной камеры ниже температуры воспламенени  взрывоопасной смеси, последн   накапливаетс  в камере.In low-temperature furnaces, when the temperature inside the heating chamber is lower than the ignition temperature of the explosive mixture, the latter accumulates in the chamber.

Дл  предотвращени  взрыва печи снабжены системой отсоса (вентил цией). Благодар  иитеисивиому отсосу смеси газов и иаров с воздухом присутствуют в концентраци х, меньших нижнего предела взрываемости этих смесей, что обеспечивает безопасность эксплуатации . Количество воздуха, требуемого дл  обеспечени  такой концентрации, как правило , во много раз превышает количество воздуха , необходимое дл  нормального ведени  технологического процесса (например, протекани  процесса сушки).To prevent an explosion, the furnaces are equipped with a suction system (ventilation). Thanks to the well-known suction of a mixture of gases and vapors with air, they are present in concentrations lower than the lower explosive limit of these mixtures, which ensures safe operation. The amount of air required to provide such a concentration is usually many times greater than the amount of air necessary for the normal conduct of the process (for example, the drying process).

Цель изобретени  - повышение к. п. д. установки .The purpose of the invention is to improve the efficiency of the installation.

Достигаетс  это тем, что в рабочей камере установлен воспламеиитель.This is achieved by the fact that an igniter is installed in the working chamber.

Печь схематически изображена на чертеже .The furnace is shown schematically in the drawing.

Устройство содержит рабочую камеру /, источник нагрева 2, воспламенитель 3 (например , электрический), установленный вблизи изделий 4. При иеобходимости может быть установлено иесколь;-:о воспламенителей. Устройство работает следующим образом.The device contains a working chamber /, a heating source 2, an igniter 3 (for example, an electric one) installed near the products 4. If necessary, it can be installed and; -: about the igniters. The device works as follows.

В ироцессе иагрева изделий, размещенных Б камере, из ипх выдел ютс  взрывоопасные пары или газы, при этом температура в камере и источников иагрева иедостаточиа дл  восиламенсии  образующейс  газовоздушной смеси . По мере накоилеи1:  смесь безопасно сжигаетс  на воспламспителе.In the process of heating the products placed in the B chamber, explosive vapors or gases are released from the IHP, while the temperature in the chamber and the sources of ignition are insufficient to increase the amount of the gas-air mixture. As nakoneili1: the mixture is safely burned on the igniter.

Дл  этого температура воспламеиител  4 поддерживаетс , заведомо более высокой, чем температура воспламенени  образующейс  газовоздушной (пли паровоздушной) смеси. В случае использовани  электрического воспламеиител  4 это достигаетс , папрпмер, соответствующим выбором величины подаваемого па воспламенитель напр жени .For this purpose, the igniter temperature 4 is maintained, which is known to be higher than the ignition temperature of the resulting gas-air (or vapor-air) mixture. In the case of using an electric igniter 4, this is achieved, by means of an appropriate choice of the magnitude of the voltage supplied to the igniter.

Предмет изобретени Subject invention

Печь дл  термообработки изделий, выдел юи1 их компоненты, образуюи1,ие взрывоопа-сные смеси, содержаща  рабочую камеру с нагревател ми и систему отсоса, отличающа с  тем, что, с целью повышени  к. п. д. установки , в рабочей камере установлен воспламенитель .A furnace for heat treatment of products, separating their components, forming explosive mixtures, containing a working chamber with heaters and a suction system, characterized in that, in order to increase the installation efficiency, an igniter is installed in the working chamber. .
