BROWN'S GAS DRYING SYSTEM AND METHOD Russian patent published in 2024 - IPC B01D53/26 

FIELD: various technological processes.

SUBSTANCE: group of inventions relates to industry, namely to a device for drying of Brown's gas of a hydrogen soldering apparatus (HSA) used for various methods of processing materials, such as soldering, welding, cutting. Brown's gas dehydration system used in the HSA comprises at least the following structural elements: a dehumidifier with an upper and a lower cover, unions with taps in the lower part of the container for withdrawing and draining the heat carrier, a foam cutter, a gas tube with a divider, a heat carrier – distilled water, the temperature of which is less than the temperature of the gas, Peltier elements for heat carrier cooling, computer coolers, one for each element for heat removal from Peltier elements, heat carrier temperature and level sensors, main line, drain pump and control system with controller. Dehumidifier represents a vessel made of stainless steel with an upper and a lower cover, containing an inlet connection for gas and an outlet connection for removal of dried gas, which are mounted on the upper cover. Gas is lowered through the gas tube with the splitter under the heat carrier mirror and is dissected into multiple flows at the outlet of the gas tube. Gas cooled to below ambient temperature is fed into the pipeline through the union and heated therein to ambient temperature. Drain pump operates according to heat carrier level sensor to return condensate taken from gas to gas generator. Also disclosed is a method of drying Brown's gas using the above drying system.

EFFECT: group of inventions provides the creation of an effective system and method of dehumidification for a HSA apparatus using Brown's gas, which enable to eliminate emissions of condensate accumulated in the hose, increase the HSA service interval to 3 working weeks, ensure uninterrupted operation of the dehumidifier, reduce or eliminate waste generation and expand the range of dehumidifiers and drying methods for the HSA.
