Detailed description of the invention

By particular specific embodiment, embodiment of the present utility model being described below, those skilled in the art the content disclosed by this specification can understand other advantages of the present utility model and effect easily.

Refer to Fig. 1 to Fig. 3. Notice, the structure of this specification institute accompanying drawings depicted, ratio, size etc., all only in order to coordinate the disclosed content of description, understand for those skilled in the art and read, it is not limited to the enforceable qualifications of this utility model, therefore do not have technical essential meaning, the adjustment of the modification of any structure, the change of proportionate relationship or size, under not affecting effect that this utility model can be generated by and the purpose that can reach, all should still drop in the scope that the disclosed technology contents of this utility model can be contained. Simultaneously, in this specification cited as " on ", D score, "left", "right", " centre " and " one " etc. term, it is merely convenient to understanding of narration, and it is not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, changing under technology contents without essence, when being also considered as the enforceable category of this utility model.

As it is shown in figure 1, this utility model provides a kind of gas-liquid separator removing mist for waste gas, described gas-liquid separator is body structure, is provided with two-layer spiral board 4 and is placed in the silk screen being made up of silk screen above spiral board 4 except mist layer 2 in casing; The sidewall of casing has air inlet 5, and air inlet 5 is positioned at the lower section of described spiral board 4; The top of casing has gas outlet 1; Space below the inherent described air inlet of casing is sewage collecting storehouse 6, and the bottom of casing has sewage draining exit 7. This utility model utilizes centrifugal force and silk screen that spiral board produces except the physics interception function of mist layer, it may be achieved the high efficiency separation of drop, particulate matter and gas.

The direction of rotation of giving vent to anger of the two-layer spiral board 4 in the present embodiment is contrary. Utilizing centrifugal force separate drop and particulate matter that two-layer spiral board 4 produces and gas to be easily separated, the direction of rotation that two-layer spiral board 4 is given vent to anger is contrary, realizes the high efficiency separation of gas-liquid, gas and particulate matter making full use of centrifugal force; The physics interception function that silk screen removes mist layer 2 is utilized to realize the purification of gas further afterwards. The flow rotation of two spiral boards 4 is in opposite direction, and so unique design can be effectively improved demisting efficiency, and demisting efficiency is up to more than 95%.

Above-mentioned spiral board 4 is polypropylene material, and as shown in Figure 2, the blade 41 on each spiral board 4 adopts up-to-date PP material to be made, and surface is through special handling, and spy is smooth and has self-lubricity, is not easy ash deposit and slag buildup in its surface. Even if some dust stratification is also easy to rinse well, reduce cleaning frequency number of times, it is ensured that spiral board runs in low-resistance, thus solving vane dust deposition fouling to cause the phenomenons such as isolation resistance increase, waste gas band water. The operation principle of spiral board is: air-flow becomes swirling eddy, drop therein and particulate matter under effect of inertia when through 41 gaps of plate leaf, spins with certain elevation angle injection and moves and be thrown toward outside, collects stream discharge in overflow launder.

Silk screen in this utility model is connected with the cleaning pipe 3 for cleaning web except mist layer 2. As shown in Figure 3, the tube wall cleaning pipe 3 is provided with multiple rows of apopore 31 towards silk screen. Clean the cleaning after pipe 3 uses certain time to be blocked for silk screen. Clean pipe 3 and adopt PE pipe or pvc pipe.

This utility model also arranges differential pressure pickup at box bottom and top, and cleaning in pipe 3 is tap water with water, arranges electromagnetic valve on the cleaning pipe outside casing, can according to pressure reduction situation of change, it is achieved control cleaning function.

The silk screen that silk screen is woven by the polyacrylic fibres of �� 0.10mm�� 0.28mm except mist layer 2 is made, and silk screen is corrugated. specifically, silk screen adopts special longitude and latitude mode to be woven into silk screen except mist layer, then the silk screen of braiding is pressed into the ripple of certain angle. all size size is made with pressing ripply silk screen. silk screen except the mechanism of action of mist layer is: carry fine liquid droplet in the gas phase secretly, through silk screen except the silk screen of mist layer, droplet is encountered except on mist silk screen, it is attached or absorbs, through repeated multiple times absorption droplet, minimum droplet agglomeration, it is coalesced as big drop, drop is under gravity, cross point along braided wires twine Yu silk moves downward, while continuing to the droplet carried secretly in adsorbed gas, the droplet stream grown up removes the bottom of mist layer to silk screen, drop down with the gravity by drop self, actually, in absorption process, due to whole silk screen except the inside of mist layer is filled with the droplet absorbed, enhance independent metal or the absorbability of engineering plastics silk, when making normal operation, silk screen increases substantially except the mist rate of removing of mist layer, minimum droplet can be adsorbed effectively and deviate from down. except mist layer, this silk screen has the advantages that pressure drop is little, specific surface area is big, demisting efficiency is high. for more than 3 ��m droplets, it can reach more than 98% except mist removes efficiency.

After silk screen removes water smoke except mist layer 2, waste gas is discharged from the gas outlet 1 at top, and this utility model realizes the good effect removing mist and particle-removing thing. Bottom space at casing is sewage collecting storehouse 6, is used for collecting isolated water smoke and particulate matter and cleaning sullage.

In sum, of the present utility model for waste gas except the gas-liquid separator of mist, it utilizes centrifugal force that spiral board produces and silk screen to remove the physics interception function of mist layer, it may be achieved the high efficiency separation of drop, particulate matter and gas. So, this utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.

Above-described embodiment only illustrative principle of the present utility model and effect thereof, not for restriction this utility model. Above-described embodiment all under spirit of the present utility model and category, can be modified or change by any those skilled in the art. Therefore, art has all equivalence modification or changes that usually intellectual completes under the spirit disclosed without departing from this utility model with technological thought such as, must be contained by claim of the present utility model.
