Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of collection tank, specifically relates to a waste gas coarse particle collection tank. BACKGROUND

[0002] In the microwave plasma waste gas treatment technology, the avalanche breakdown is caused by the electromagnetic field, and the microwave plasma discharge is caused by the plasma gas. In this process, the microwave radiation is converted into thermal plasma energy, and the center temperature of the high-temperature plasma torch formed can reach 6000K. It has unique physical and chemical properties such as high temperature, high enthalpy and high oxidation, which can effectively treat organic pollutants in waste gas and make them into harmless gases such as CO2, NOX and H2O.

[0003] However, in the actual treatment process, in order to avoid the electrode from discharging to the outside to accelerate the electrode wear, there are usually two coping methods. The first one is to enlarge the cross-sectional area of the treatment chamber, which can increase the distance between the electrode and the inner wall of the treatment chamber to meet the discharge condition, but it will greatly prolong the time required for the treatment chamber to heat up to the temperature required for treating waste gas, and even it may be necessary to replace the high-power equipment due to the failure to meet the temperature requirement, resulting in that this method is rarely used due to its low efficiency. The second one is to install an insulating glass cylinder in the treatment chamber, which can ensure the insulation of the electrode without changing the cross-sectional area of the treatment chamber, and the quartz glass can withstand the conventional treatment temperature, so it is widely used. However, when there are coarse particles in the waste gas, this method will expose serious defects. Because the coarse particles have large mass, they are easy to deposit at the bottom of the glass cylinder, and the conductive components in them can cause discharge with the electrode. At the same time, the high-temperature plasma torch is easy to melt and agglomerate the coarse particles, which not only interferes with the electrode discharge, but also blocks the treatment chamber. Therefore, when treating waste gas containing high-concentration coarse particles, it is necessary to remove dust in advance.

[0004] The current common dust removal methods include bag filter, electrostatic precipitator, cyclone dust collector and wet dust collector. The bag filter relies on the initial layer of dust on the filter bag to intercept dust, and when the accumulated dust is too much, the dust will fall into the ash bucket by shaking the filter bag. The electrostatic precipitator makes the dust charged in the discharge channel and then adsorbed on the negative electrode, and when the accumulation reaches a certain degree, it will be shaken off. The cyclone dust collector uses the centrifugal force generated by the rotation of the dust-containing gas flow in the cylinder to separate the dust. The wet dust collector makes the dust and water mist combined and settled by the contact between the dust-containing gas flow and the spray water. These methods can effectively remove coarse particles and suspended fine particles, but suspended fine particles are mostly organic pollutant aerosols, which belong to the treatment range of microwave plasma waste gas treatment equipment. After being treated by the above-mentioned dust removal methods, they are only converted into solid waste or waste liquid form, and still need secondary purification treatment of organic pollutants. In view of this, it is very important to develop a collection device for coarse particles in waste gas only for the microwave plasma waste gas treatment process. UTILITY MODEL CONTENTS

[0027] A waste gas coarse particulate collection tank.

[0028] In this embodiment: To solve the technical problems existing in the prior art, as disclosed in the above BACKGROUND, "the current commonly used dust removal methods include bag filter, electrostatic precipitator, cyclone dust collector and wet dust collector. The bag filter relies on the initial layer of dust on the filter bag to intercept dust, and when the dust accumulation is too much, the dust falls into the ash bucket by shaking the filter bag; the electrostatic precipitator makes the dust charged in the discharge channel and then adsorbed on the negative electrode, and when the accumulation reaches a certain degree, it is shaken off; the cyclone dust collector uses the centrifugal force generated by the rotation of the dust-containing gas flow in the cylinder to separate the dust; the wet dust collector makes the dust combine with the water mist and then settle by contacting the dust-containing gas flow with the spray water. These methods can effectively remove coarse particles and suspended fine particles, but suspended fine particles are mostly organic pollutant aerosols, which belong to the processing range of microwave plasma waste gas treatment equipment, and after being treated by the above-mentioned dust removal methods, they are only converted into solid waste or waste liquid form and still need secondary purification treatment of organic pollutants", in combination with actual use, this problem is obviously a real problem and is relatively difficult to solve. Therefore, in order to solve this technical problem, a waste gas coarse particle collection tank is provided on this basis.

[0029] As Figs. 1-2 shown in the figure;

[0030] In combination with the above, including:

[0031] The tank body support 1 is used to support the entire collection tank;

[0032] The tank body 4 is provided with a tank cover 9 at the top, and double-layer discharge valves, i.e. a discharge valve A2 and a discharge valve B3, are installed at the bottom of the tank body 4;

[0033] The gas inlet 5 is arranged on the side of the tank body 4 and is used for the inlet of waste gas;

[0034] The spoiler group 6 is arranged in the tank body 4, and the spoiler group 6 is composed of multiple layers of spoilers, each layer of spoiler is provided with multiple through holes, the total area of all through holes is greater than the area of the gas inlet 5, and the spoilers are arranged obliquely;

[0035] The spoiler fan 7 is arranged on the tank top and is a non-powered fan blade;

[0036] The vibrator 8 is installed outside the tank body 4;

[0037] The gas outlet 10 is arranged on the tank cover 9 and is used for the discharge of treated gas.

[0038] In an optional embodiment, the discharge valve A2 and the discharge valve B3 can be independently opened and closed, so as to realize the discharge of internal dust accumulation when the collection tank is working.

[0039] In an optional embodiment, the vibrator 8 can periodically vibrate the tank body 4, so as to facilitate the dust accumulation on the spoilers to fall into the bottom of the tank body 4.

[0040] In an optional embodiment, the multiple layers of the spoiler group 6 block each other's through-holes to increase wind resistance and reduce gas flow rate.

[0041] In an optional embodiment, the gas passing through the spoiler can push the fan blades of the spoiler fan 7 to rotate, so that the kinetic energy of the gas is reduced and the wind speed is further reduced.

[0042] In the present embodiment: a spoiler group is arranged in the tank body, the spoiler is densely covered with multiple through-holes, and the total area of all through-holes is greater than the area of the gas inlet. The multiple layers of the spoiler cooperate with each other, and the through-holes of the spoiler are staggered and blocked, which greatly increases the wind resistance and further reduces the gas flow rate. At the same time, the spoiler is installed in an inclined manner, which ensures the smooth passage of the gas and makes the settled coarse particles more smoothly slide to the bottom of the tank under the action of gravity, and the multiple through-hole design effectively reduces the possibility of the falling particles being blown up by the gas flow.

[0043] In an optional embodiment, the inclined design of the spoiler makes it easier for the settled particles to slide to the bottom of the tank, and the multiple through-hole design reduces the degree of the falling particles being blown up by the gas flow.

[0044] In the waste gas treatment operation, the waste gas containing coarse particles enters the inside of the tank body 4 from the gas inlet 5. The waste gas first encounters the spoiler group 6, and due to the special structural design of the spoiler group, the gas flow rate is rapidly reduced, and the coarse particles begin to settle under the action of their own gravity. After the preliminary treatment of the gas by the spoiler group, the gas continues to flow to the spoiler fan 7 at the top of the tank, and in this process, the gas consumes a large amount of kinetic energy by pushing the blades of the non-powered spoiler fan to rotate, further slowing down the flow rate, so that the remaining coarse particles in the gas can settle again. The clean gas after two times of settlement is finally discharged from the exhaust port 10.

[0045] The coarse particles deposited on the spoiler group will gradually slide to the bottom of the tank through the through-holes of the spoiler group under the action of their own gravity and the periodic vibration of the tank vibrator 8. When it is necessary to clean the coarse particles accumulated at the bottom of the tank, the material falling valve B3 and the material falling valve A2 can be controlled respectively to safely and efficiently discharge the accumulated dust, ensuring the continuous and stable operation of the collection tank and meeting the continuous production requirements of the waste gas treatment process.

[0046] During the entire operation process, the operator should regularly check the running state of the equipment according to the equipment operation procedures, including the dust accumulation of the spoiler group, the sealing and flexibility of the material falling valve, the working performance of the vibrator, and the overall structural integrity of the tank body, etc., to ensure that the equipment is always in good running state, fully plays its function of collecting coarse particles, and guarantees the efficient and stable operation of the microwave plasma waste gas treatment system.

[0047] Finally, it should be noted that: the above is only the preferred embodiment of the utility model, and is not used to limit the utility model, although the utility model is described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or make equivalent replacement to part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
