Embodiment 1

[0018] In Embodiment 1, the connecting portion of the gas generator 1 and the inlet separator 4 further includes a dust filter 11 connected to the gas generator 1 , and the dust filter 11 connected to a preheating dryer 12 . The dust filter 11 is used for preliminary impurity removal of the mixed gas generated in the gas generator 1, and the mixed gas from which the impurities are removed enters the preheating dryer 12, and the mixed gas is preheated by the preheating dryer 12 and its content is removed. of water vapor.

Embodiment 2

[0019] In the second embodiment, the connection between the freeze dryer 7 and the third gas tank 53 also includes a deep dryer 8, the freeze dryer 7 is connected to the deep dryer 8, and the deep dryer 8 is connected to the third gas tank 53 . The mixed gas output by the freeze dryer 7 can pass through the deep dryer 8 to further reduce the dew point of the gas.

Embodiment 3

[0020] In the third embodiment, the third gas storage tank 53 is connected with a fourth gas storage tank 54 . Since the gas pressure generated by the third gas storage tank 83 is relatively high and the dew point temperature is lowered, the gas output from the third gas storage tank 53 is buffered by the fourth gas storage tank 54 to facilitate gas extraction from the fourth gas storage tank 54 .

Abstract

The invention discloses a low-dew-point gas generator, which comprises a gas generator and a freezing dryer. The gas generator is connected with a gas inlet separator. The gas inlet separator is connected with a first gas storage tank. The first gas storage tank is connected with a mixed gas compressor and used for increasing the pressure of gas output by the first gas storage tank. The mixed gas compressor is connected with an oil-water separator. The oil-water separator is connected with a second gas storage tank. The second gas storage tank is connected with the freezing dryer. The freezing dryer is connected with a third gas storage tank. According to the low-dew-point gas generator disclosed by the invention, the dew-point temperature of the low-dew-point gas generator can be within a required range, thus, the requirements of a special treating process can be satisfied.

Description

technical field [0001] The invention relates to a gas generating device, in particular to a low dew point gas generating device. Background technique [0002] The low dew point gas generator is mainly used for heat treatment equipment that requires a high dew point of the protective gas. The equipment produces protective gas through the incomplete combustion of natural gas, and its main components are: CO, H 2 、H 2 O, N 2 etc. Since the outlet pressure of the protective gas is very small, generally only 5-10KPA, it is extremely difficult to make the dew point of the gas reach -50°C. The existing devices produced by most domestic manufacturers generally only connect the gas generator equipment body, water cooling equipment, and cold dryers, so the pressure of the mixed gas cannot be increased, and the dew point temperature of the gas generator is only 3-5°C. , but this dew point temperature cannot meet the special processing requirements.
