Embodiment 1

[0022] Embodiment 1, a gas filter with integrated refrigeration function, the structural diagram is as follows figure 1 As shown, it includes two parts: refrigeration mechanism and filter mechanism. The refrigeration mechanism includes a cooling chamber 4 , a semiconductor refrigeration sheet 5 and a radiator 6 . The filter mechanism includes a metal cover 2 and a filter 3 . The cooling bin 4 has a second air inlet 41 and a second air outlet 42. The cooling surface 51 of the semiconductor refrigeration sheet 5 is close to the cooling bin 4, and the heating surface 52 is close to the radiator 6, so as to facilitate the cooling of the cooling bin 4. Cooling and dissipating heat from the heating surface 52 . The filter 3 has a first air inlet 31 and a first air outlet 32. The filter 3 is closely attached to the cooling chamber 4, so that the second air outlet 42 and the first air inlet 31 are butted and communicated. The sequence of the port 41 - the second air outlet 42 - the...

Embodiment 2

[0027] Embodiment 2 is different from Embodiment 1 in that it further includes a thermal insulation shell 1, such as Figure 4 As shown, the heat insulation shell 1 has a heat insulation function, which can reduce the heat exchange between the gas and the outside world, and reduce the cooling load. The cooling chamber 4, the filter 3, and the metal cover 2 are all arranged in the heat insulation shell 1. A hole through which the air outlet passes.

Embodiment 3

[0028] Embodiment 3, different from Embodiment 1 and 2, is that a temperature sensor (not shown in the figure) is further set at the first air outlet of the filter or the second air outlet of the refrigeration compartment, and the temperature sensor can detect the temperature after cooling. The temperature of the gas, so as to control the cooling capacity of the semiconductor refrigeration chip; realize the filtration of the gas at a specific temperature.

[0029] To sum up, the present invention integrates the refrigeration mechanism and the ordinary filter mechanism into a whole, which improves the filtering effect of the ordinary filter mechanism, and because the integrated volume is small, it can be installed in equipment that needs to filter and dehumidify the flowing gas ( such as air compressors).

[0030] The present invention can also realize the following functions through changes:

[0031] 1) By controlling the cooling temperature, the separation of gases with diff...

Abstract

The invention discloses a gas filter device with integrated refrigeration function, which includes a filter mechanism, the filter mechanism has a first air inlet and a first air outlet, and also includes a refrigeration mechanism, and the filter mechanism is closely attached to the refrigeration mechanism. The refrigerating mechanism has a second air inlet and a second air outlet, the second air outlet and the first air inlet are butt-connected, and according to the second air inlet, the second air outlet, the first air inlet The sequence from the gas port to the first gas outlet is connected to form an air flow channel through which gas enters and exits. The invention liquefies the moisture and oil mist in the gas by cooling before filtering, thereby improving the water and oil removal effect of the filter.

Description

【Technical field】 [0001] The invention relates to a gas filter, in particular to a gas filter device for assisting gas filtration through refrigeration. 【Background technique】 [0002] Filters are required in many devices to filter out moisture and oil mist in the gas. At present, this kind of filter mainly includes filter element type and centrifugal type. [0003] The working principle of the filter element filter: when the gas containing liquid moisture and oil mist passes through the filter element, most of the water and oil mist will condense and gather on the filter element due to the limitation of the filter pore size (usually between 100 and 0.01um). , while the gas quickly passes through the filter element, so as to realize the separation of water, oil and gas. [0004] The working principle of the centrifugal filter: through a certain mechanical design, the gas containing liquid water droplets and oil mist is rotated, and under the action of centrifugal force, th...
