As shown in fig. 1, the apparatus for preventing dew condensation on the surface of the filter element specifically includes a front replacement heat unit 100 and a heat exchange medium supply unit 200.
The front heat exchange unit 100 comprises a gas transmission box 110, the gas transmission box 110 has a gas inlet 111 connected to a source of gas to be filtered and a gas outlet 112 connected to an input port of the gas to be filtered of the filtering device 300, and a first heat exchange device 120 for exchanging heat between the gas to be filtered and a heat exchange medium is arranged on a gas transmission channel between the gas inlet 111 and the gas outlet 112 in the gas transmission box 110.

The device for preventing the surface of the filter element from dewing can adjust the temperature of the gas to be filtered, so that the relative humidity of the gas to be filtered is reduced, and the surface of the filter element is effectively prevented from dewing. Due to the gas transmission box 110, the gas to be filtered can be fully acted by the first heat exchange device in the process of passing through the gas transmission box 110.
The heat exchange medium is preferably water, and under the condition, the first heat exchange device is a dividing wall type water cooler, and the second heat exchange device is a water cooler. The dividing wall type water cooler and the water cooler belong to the existing equipment, and can stably and effectively reduce the temperature of the gas to be filtered by a certain temperature when being matched, if the gas to be filtered is ambient air under the condition of high-humidity weather in summer, the relative humidity of the gas (air) to be filtered can be ensured to reach the state of not separating out liquid water by the technical means.
As shown in fig. 1, the heat exchange medium diversion driving assembly 210 may specifically adopt the following structure: comprises a constant temperature water tank 211, a front end water pipeline and a rear end water pipeline; the front end water conveying pipeline comprises a front end water feeding pipe 212, a front end water return pipe 213 and a water pump 214 arranged on the front end water feeding pipe 212 and/or the front end water return pipe 213, two ends of the front end water feeding pipe are respectively connected with a front end water outlet of the constant temperature water tank 211 and a dividing wall type water cooler water inlet, and two ends of the front end water return pipe 213 are respectively connected with a front end water return port of the constant temperature water tank 211 and a dividing wall type water cooler water outlet; the rear-end water pipe comprises a rear-end water supply pipe 215, a rear-end water return pipe 216 and a water pump 217 arranged on the rear-end water supply pipe 215 and/or the rear-end water return pipe 216, two ends of the rear-end water supply pipe 215 are respectively connected with a rear-end water outlet of the constant-temperature water tank 211 and a water inlet of the water cooling machine, and two ends of the rear-end water return pipe 216 are respectively connected with a rear-end water return port of the constant-temperature water tank 211 and a water outlet of the water cooling machine.
The heat exchange medium flow guide driving assembly 210 with the structure can ensure that water entering the dividing wall type water cooler as a heat exchange medium is constant in temperature all the time, so that the consistency of the cooling effect of the gas to be filtered is ensured.
As shown in fig. 1-2 and 5, the filtering system to which the above-mentioned device for preventing dew condensation on the surface of the filter element is applied comprises a filtering device 300 and a driving device 400; the filtering device 300 comprises a raw gas cavity 310 provided with a gas inlet to be filtered and a clean gas cavity 320 provided with a filtered gas outlet, wherein the raw gas cavity 310 and the clean gas cavity 320 are separated by a filtering element 330; the driving device 400 is used for driving the gas to be filtered to flow into the original gas chamber 310 from the gas to be filtered inlet, then flow into the gas purifying chamber 320 through the filter element 330 to become filtered gas, and flow out from the filtered gas outlet; in addition, the filter device 300 is connected to the above-described device for preventing dew condensation on the surface of the filter element, that is, the exhaust port 112 of the gas delivery box 110 is connected to the gas input port of the filter device 300 for gas to be filtered.
In one embodiment of the filter system of the present invention, as shown in fig. 1, the gas transmission tank 110 and the filter device 300 are horizontally disposed such that the entire passage from the gas inlet 111 of the gas transmission tank 110 to the raw gas chamber 310 of the filter device 300 extends in a horizontal straight line, and the filter element 330 of the filter device 300 is a filter tube having a central axis parallel to the horizontal plane. Therefore, the gas to be filtered flows in the gas transmission box 110 and the original gas cavity 310 along the horizontal direction all the time, the gas flow does not turn, and the pressure loss is small.
Fig. 3 is a schematic view of an internal partial structure of the filter device in fig. 2. Fig. 4 is a partially enlarged view of a portion a in fig. 3. As shown in fig. 3 to 4, a perforated plate 340 is provided between the raw air chamber 310 and the clean air chamber 320 of the filter device 300, and the filter element 330 is installed on each installation hole of the perforated plate 340.
In order to facilitate the fastening of the filter element 330 in the corresponding mounting hole of the perforated plate 340, a fastening element for fastening the filter element is used, which is produced as a profile, which, viewed in cross section, comprises: the shoulder plate 351 is provided with a connecting piece mounting hole, and the left side and the right side of the shoulder plate form a shoulder respectively; a base plate 352 provided opposite to the shoulder plate 351 and provided with a connector mounting hole corresponding to the connector mounting hole on the shoulder plate 351; a left side plate 353 connected between the root of the left shoulder of the shoulder plate 351 and the left side of the bottom plate 352; and a right side plate 354 connected between a base of the shoulder on the right side of the shoulder plate 351 and the right side of the bottom plate 352.
In use, the fasteners used to secure the filter element are secured to the aperture plate 340 by threaded connectors 360 (which may be, in particular, bolts having threaded shafts that pass through connector mounting holes in the shoulder plate 351, connector mounting holes in the base plate 352, and post-aperture coupling nuts in the aperture plate 340, respectively). The left and right shoulders of the fastening member for fixing the filter element are pressed against the stepped surfaces of the corresponding filter element 330, respectively, thereby pressing the filter element 330 against the orifice plate 340.
The fastener for fixing the filter element is high in strength, not easy to deform and very convenient to mount and dismount. Especially when the filter element 330 is a filter element having an integral structure of a plurality of linearly arranged filter tubes, as disclosed in the above-mentioned patent application publication No. CN103089714A, since the fastening member for fixing the filter element is formed in a shape having a certain length, a side shoulder can simultaneously press the stepped surface on the entire edge of the head of the filter element having an integral structure of a plurality of linearly arranged filter tubes, resulting in a better seal between the filter element 300 and the orifice plate 340.
Preferably, in the fastening tool for fixing the filter element, the left side plate 353 and the right side plate 354 are disposed to face each other in an inclined manner, and each of the left side plate 353 and the right side plate 354 forms a waist of an isosceles trapezoid having the bottom plate 352 as an upper base and the shoulder plate 351 as a lower base.
Preferably, the fastening element for fastening the filter element is manufactured as an aluminium alloy profile.
In addition, the outlet 112 of the gas transmission tank 110 is connected to the inlet of the gas to be filtered of the filtering device 300 by a tapered hose 600, and the diameter of the tapered hose 600 at the end connected to the inlet of the gas to be filtered is larger than the diameter at the end connected to the outlet 112. The air transmission tank 110 is flexibly connected with the filtering device 300 through the conical hose 600, so that the manufacturing and installation errors of equipment can be better adapted; since the diameter of the tapered hose 600 at the end connected to the inlet port of the gas to be filtered is larger than the diameter at the end connected to the exhaust port 112, the gas to be filtered enters the original air chamber 310 of the filter device 300 at a more uniform and stable pressure and flow rate.
The above-described filtering system is particularly suitable as a filtering system used under the condition that the driving device 400 is an air compressor connected to a filtered gas outlet of the filtering device 300, the filtering device 300 is an air filter preceding the air compressor, and the source of the gas to be filtered is the atmospheric environment outside the air filter. The air compressor may specifically be a turbine compressor.
On the basis, in order to better prevent the surge problem of the air compressor (especially the turbine compressor), as shown in fig. 5, an air pressurizing device 500 is further connected to the gas inlet to be filtered of the filtering device 300. The air supercharging device 500 may be a booster fan.
In addition, the gas inlet of the filtering device 300 to be filtered may be connected with a first air inlet channel and a second air inlet channel which can be switched with each other, and the air supercharging device 500 may be disposed on any one of the first air inlet channel and the second air inlet channel. In this way, when the air-pressure boost device 500 is required to be used, one of the first and second intake passages in which the air-pressure boost device 500 is provided may be selected, and when the air-pressure boost device 500 is not required to be used, one of the first and second intake passages in which the air-pressure boost device 500 is not provided may be selected.
