Abstract

The invention discloses a gas filtering device with an automatic temperature regulating function. A side surface of a base is connected with a heat exchanger; the heat exchanger comprises a gas channel and a water channel; the gas channel is separated from the water channel through cooling fins; a gas inlet end of the gas channel is connected with a gas filtering device; a gas outlet end of the gas channel is connected with a technological gas outlet hole formed in the base through a bent tube; a water inlet end of the water channel is provided with a threaded connector; a water outlet end of the water channel is connected with a technological water outlet hole in the base; and a temperature regulator is arranged between the technological gas outlet hole and the technological water outlet hole. A gas filtering function, a heating function and a temperature regulating function are integrated. The gas filtering device is compact in structure and occupies small space; the number of connecting pipes and the number of control circuits are reduced; the cost is also reduced; and moreover, the gas filtering device is easy to assemble and disassemble and convenient to maintain.

Description

technical field [0001] The invention relates to a gas filter device, in particular to a gas filter device with automatic temperature adjustment. Background technique [0002] In recent years, with the dual pressure of energy and environment, gas engines using natural gas as an alternative fuel have developed rapidly. At present, there are two main ways to use natural gas as fuel in China: one is CNG, that is, compressed natural gas; the other is LNG, that is, liquefied natural gas. Since natural gas has impurities such as water vapor, tar, and dust, it is necessary to add a filter device to filter the impurities and oil mist in the natural gas to protect the nozzles and other precision components in the gas system from damage. As natural gas drops from high pressure to low pressure, the temperature of the gas will drop significantly, sometimes even below -70°C, so a heat exchanger must be used to heat the natural gas to ensure the service life of the injection valve; when t...
