Spray column for multi-exhaust gas purification

Abstract: The utility model discloses a spray tower used for purification of multiple exhaust gas, which comprises vent ports distributed from top to bottom in the tower body, a plurality of layers of spray layer, an inlet chamber and a liquid tank. A water pump is connected with a spray pipe of each layer of spray layer; the air inlet of the inlet chamber penetrates deeply into the tower body and presents an inclination angle with the tower body; the spray layer is formed by a filler contacting section and an atomization section, and the height ratio of the filler contacting section and the atomization section is less than 1. A preference technical proposal of the spray tower of the utility model is that: the inner end of the air inlet and the tower body present an angle of 45 degrees; the height ratio of the filler contacting section and the atomization section is 0.95 to 1; a nozzle on the spray pipe adopts an atomization nozzle; the atomization nozzle adopts an atomization device without jam; wind speed of the empty tower of the spray tower is 0.78 to 0.8 m per second. The spray tower of the utility model has the advantages of non-jam nozzle, symmetrical gas distribution, reasonable ratio of the inner height of the spray layer and high purification efficiency.

Removal of co2 from combustion exhaust gas

Abstract: PURPOSE:To remove CO2 from combustion exhaust gas while preventing the deterioration of a CO2 absorbing solution and the lowering of CO2 removing efficiency by subjecting combustion exhaust gas to wet desulfurization treatment and removing CO2 from the treated exhaust gas before removing a harmful substance therefrom. CONSTITUTION:At first, combustion exhaust gas is treated in a wet desulfurization process 2 due to a limestone/gypsum method or a gas bubbling method. Subsequently, the exhaust gas after desulfurization treatment is treated in a CO2 separating process 4 due to a monoethanolamine method to remove CO2. Further the exhaust gas after the treatment in the CO2 separating process 4 is washed in a spray tower 5 using city water to remove a harmful substance. As mentioned above, since wet desulfurization treatment is performed prior to the removal of CO2 in the exhaust gas, dust, SOx and the like are reduced and the deterioration of a CO2 absorbing solution is eliminated and CO2 can be effectively removed.

Waste gas treatment method and treatment equipment

Abstract: PROBLEM TO BE SOLVED: To provide a waste gas treatment method and treatment equipment which are capable of efficiently utilizing slightly excessive desuperheating water to be cyclically used. SOLUTION: In the waste gas treatment method of introducing the waste gas containing hazardous components into a waste gas desuperheating column 1 of a water spray system and cooling the same, then introducing the waste gas into dust collector equipment 2 and removing the dust in the waste gas and in succession introducing the gas into a wet process spray tower 3 to remove the hazardous components in the waste gas, the wet process spray tower 3 consists of at least a liquid chemical spray section 3a which removes the acidic components in the waste gas by spraying the liquid chemical and a desuperheating section 3b which recovers and desuperheats the mist in the waste gas by cooling the waste gas past the spray section 3a and cyclically uses the desuperheating water. At least a portion of the desuperheating water produced in this desuperheating section 3a is used for the spray water of the waste gas desuperheating column 1.

Multilevel combined waste gas purification treatment system

Abstract: The utility model discloses a multilevel combined waste gas purification treatment system which is characterized by comprising the following four purification plants: a condenser, a photocatalyst purification tower, an active carbon purification tower and a spray tower, wherein the four purification plants are connected in sequence, the gas outlet end of the spray tower is connected with an exhaust fan, and the lower end of the condenser is connected with a condensate recycling container. In the system, the four waste gas purification plants are combined to purify the waste gas in four levels, the system is suitable for treating high-concentration waste gases of places such as petrochemical plant and pharmaceutical factory, the system is both capable of partially recycling the organic waste gas and completely purifying the organic waste gas, the operation of the equipment is safe, the energy consumption is low, and the applicability is strong.
