Exhaust gas spray tower with built-in heat exchange

Abstract: The utility model discloses an exhaust gas spray tower with built-in heat exchange The exhaust gas spray tower mainly comprises a spray tower barrel, a water inlet thermometer, a water outlet thermometer, a shower nozzle, a washing liquid collecting tank, a lower mounting plate, a water outlet ring vessel, a heat exchange tube, an upper mounting plate, and a water inlet ring vessel The exhaust gas spray tower is characterized in that the circulating water inlet is connected with the water inlet ring vessel by a pipeline; the water inlet thermometer is arranged at the circulating water inlet; the circulating water outlet is connected with the water inlet ring vessel by the pipeline; and the water outlet thermometer is arranged at the circulating water outlet The exhaust gas spray tower has the beneficial effects that exhaust gas is rapidly cooled through the heat exchange tube; the washing liquid sprayed from the shower nozzle captures the pollutants; the temperature of the circulating water ascends through the heat exchange tube; and heat of exhaust gas is transferred to circulating water Thus, cyclic utilization of heat energy is achieved

Spray tower with observation window self - cleaning function

Abstract: The utility model discloses a spray tower with observation window self - cleaning function, including spray tower body, observation window, horizontal slide rail, vertical elevator motor, vertical lifter, horizontal telescopic link, transversely flexible motor, outer metal slip, window cleaner and pendulum rod. The observation window is sealed to set up on spray tower body side wall surface this internal light that still is provided with of spray tower, vertical elevator motor slides and sets up on horizontal slide rail, and is connected with outer metal slip, horizontal telescopic link can beperiodic flexible, window cleaner sets up the inboard wall at the observation window to adsorb mutually with outer metal slip, the pendulum rod top is articulated mutually with window cleaner. The utility model discloses can not change current spraying tower body structure, do not influence the prerequisite of spray tower gas tightness under, it has had the observation window conveniently to observe spray lance, nozzle angle and spraying effect to make, it is clear that the effect is observed to the observation window, the difficult pollution.

Method for high-temperature efficient catalytic degradation on VOCs (volatile organic compounds) waste gas in pharmaceutical industry

Abstract: The invention discloses a method for high-temperature efficient catalytic degradation on VOCs (volatile organic compounds) waste gas in pharmaceutical industry, and belongs to the technical field of waste gas control. The method comprises the following steps that firstly, the waste gas enters a first spray tower from the bottom and collides with alkaline spray liquid sprayed from top to bottom; acidic ingredients are neutralized to form salt; dust is caught and is discharged out from the bottom; the waste gas is exhausted from the top; the waste gas enters a second spray tower; soluble ingredients in the waste gas are dissolved to form a dissolving solution to be discharged out from the bottom; ozone is introduced into the waste gas exhausted from the top; under the effect of a nano rare-earth composite catalyst loaded with Pd elements, the ozone and moisture in the waste gas take a reaction; generated O2 and hydroxyl radicals take an oxidation reduction with the waste gas to generate CO2 and H2O; the waste gas treatment is completed. The treatment method has the advantages that the heating is not needed, and the treatment can be performed at normal temperature, so that the required cost is lower, and the method can be suitable for being used for large-scale pharmaceutical VOCs waste gas dealing.

The influence of spraying angle on aerodynamic characteristics of FGD spray towers

Abstract: A model for aerodynamic characteristics predictions of flue gas desulfurization scrubber was developed. Droplets motion was considered as two-dimensional and initial droplets velocity and spraying angle were assumed as parameters. The presented model is able to predict pressure drop caused by the presence of spray, local dispersed phase concentration and droplets residence time for co- or counter-current apparatus. The results obtained for constant initial, vertical component of droplets velocity were compared to those evaluated for constant initial drops velocity (module). A range of applicability of one-dimensional model developed only for vertical drops motion is given.

Spray tower for cooling, humidifying and cleaning gas and its method

Abstract: PURPOSE:To provide a spray tower for cooling, humidifying and cleaning a gas without generating waste water due to the collision of the sprayed droplet with the inner wall of the tower and without dust being stuck to the inner wall. CONSTITUTION:This dry spray tower has a part 2 expanding successively from the top of the tower having a gas inlet 1 and an expanding part for spraying water and/or a liq. absorbent to cool and humidify the gas and/or to remove a harmful component or a spray nozzle fixed directly behind the expanding part and never generates waste water. A gas flow straightening device 6 is provided to the expanding part 2 on the upstream side of the nozzle 4 to make the flow velocity of the downward component higher at the peripheral part than at the central part. Accordingly, a perforated plate with the rate of perforation made larger at the peripheral part than at the central part, a perforated plate with the peripheral part slit, etc., are preferably used as the device 6.
