The utility model is described in further detail below with reference to the drawings and detailed description.
Detailed Description
As shown in fig. 1, this embodiment provides a water ring vacuum pump flue gas and exhaust gas treatment device, which is mainly used for treating flue gas and exhaust gas generated by the operation of a water ring vacuum pump, and can also be used for treating other exhaust gas with high contents of substances such as high temperature, high humidity, dust, VOCs and the like similar to the flue gas and exhaust gas of the water ring vacuum pump. The water ring type vacuum pump flue gas and waste gas treatment device comprises a water blocking tower 1, a heat exchanger 2, a demister 3, a dry filter 4 and an adsorption component 5 which are sequentially arranged along the airflow direction, namely the flow direction of waste gas.
When the flue gas and waste gas treatment device of the embodiment works, waste gas firstly passes through the water blocking tower 1 to remove large-particle water; then the waste gas temperature is reduced through the heat exchanger 2, and the high-temperature high-humidity water vapor is changed into water mist and water mist into water drops after the temperature is reduced and the water vapor is changed into water drops after the temperature is lower than the dew point, so that condensed water is formed, and the air humidity is further reduced; then the waste gas enters a demister 3, smaller water mist is further removed through the demister 3, the humidity of the waste gas is greatly reduced, and the gas entering subsequent equipment is ensured to be dry; and then enters a dry filter 4, and particles such as dust in the waste gas are removed through a filter material, so that the influence on the subsequent adsorption is avoided. And then enters an adsorption component 5 to thoroughly remove VOCs components in the waste gas, and finally the waste gas reaches the standard for discharge.
One or more baffles can be arranged in the water blocking tower 1, so that large-particle water drops in the flue gas and waste gas of the water ring type vacuum pump are trapped in the water blocking tower 1, and a large amount of water in the high-humidity waste gas is removed first, so that the influence on the subsequent heat exchange efficiency is avoided. The heat exchanger 2 can be internally provided with a gas channel and a heat exchange tube arranged in the gas channel, and the heat exchange tube can be internally provided with a heat exchange working medium such as water and the like to exchange heat with high-temperature waste gas so as to reduce the temperature of the waste gas. The demister 3 may be provided with a plurality of layers of packing, and the packing is used to further adsorb moisture. The dry filter 4 may be one or more of a plate-type primary filter and a bag-type medium-efficiency filter, and is used for removing particles such as dust in the dry air treated by the demister 3, so as to avoid the particles from blocking the adsorption assembly 5. Finally, the adsorption component 5 adsorbs substances such as VOCs in the exhaust gas, and the gas entering the adsorption component 5 is low-temperature, low-humidity and low-dust-content exhaust gas, so that the service life of the adsorption component 5 can be prolonged.
In some exemplary embodiments, the device further comprises a cooling tower 6 connected to the heat exchanger 2, the cooling tower 6 is used for radiating heat exchange medium of the heat exchanger 2, and the cooling tower 6 can be used for radiating heat by air cooling or water cooling.
In some exemplary embodiments, the heat exchanger 2 and the cooling tower 6 are connected by a water pipe 7 to form a circulating water loop. The water pipe 7 can be divided into two sections, one section is connected with the water inlet of the heat exchanger 2 and the water outlet of the cooling tower 6, the other section is connected with the water outlet of the heat exchanger 2 and the water inlet of the cooling tower 6, and any section of water pipe 7 or the heat exchanger 2 or the cooling tower 6 is also provided with a pump to promote water flow circulation.
In some exemplary embodiments, the adsorption module 5 includes at least two activated carbon adsorption tanks in series to thoroughly absorb VOCs.
In some exemplary embodiments, the device further comprises a fan 8, the fan 8 is arranged at the downstream of the adsorption component 5 along the airflow direction, and the gas which is completely subjected to purification treatment such as cooling, dehumidifying, dedusting, deodorizing and the like is sucked and discharged through the negative pressure of the fan 8, so that the service life of the fan 8 can be prevented from being influenced by waste gas.
In some exemplary embodiments, the apparatus further comprises a chimney 9, the chimney 9 being arranged downstream of the fan 8 in the direction of the air flow, the chimney 9 being arranged to discharge the treated exhaust gases to a higher position, avoiding blowing at the ground.
In some exemplary embodiments, the fan 8 is a centrifugal fan, which is high in wind power and low in cost.
In some exemplary embodiments, the water blocking tower 1, the heat exchanger 2, the demister 3, the dry filter 4, and the adsorption assembly 5 are connected by the air pipe 10, and the air pipe 10 may be made of a plastic material, etc., preferably having a certain flexibility, to allow the respective components to vibrate without the air pipe 10 being separated from the interface.
In some exemplary embodiments, the air outlet of the water blocking tower 1 is disposed at the top end of the water blocking tower 1, and the water vapor carried by the air outlet of the water blocking tower 1 can be reduced due to the downward flow of water under the action of gravity.
In some exemplary embodiments, the air outlet of the mist eliminator 3 is provided at the top end of the mist eliminator 3. Because water flows downwards under the effect of gravity, the filler water content that is located the lower extreme in the defroster 3 is great, and air current and water countercurrent flow, dehumidification effect is better.
