Description

a desulfurization tower

technical field

The utility model relates to a desulfurization tower.

Background technique

The main air pollutants emitted during the non-ferrous metal smelting process are high-sulfur waste gas, which is characterized by high pollutant concentration, large air volume, corrosiveness, and difficult treatment. At present, the wet exhaust gas treatment technology is mainly based on the spray treatment tower. Its working principle is: the exhaust gas is introduced into the purification tower through the air pipe, and passes through the packing layer. After the exhaust gas is purified, it is dehydrated and defogged by the demister plate, and then discharged into the atmosphere by the fan. The absorption liquid is pressurized by the water pump at the bottom of the tower, sprayed down from the top of the tower, and finally returned to the bottom of the tower for recycling. At present, the spray devices of wet tail gas treatment equipment commonly used to treat high-concentration sulfur-containing tail gas are mostly single-stage single-layer or single-stage multi-layer with limited treatment effect.

Utility model content

The utility model aims to overcome the problem of low treatment efficiency of high-concentration sulfur-containing gas (non-ferrous metal smelting waste gas) in the prior art, and provides a desulfurization tower.

In order to achieve the above object, the technical solution provided by the utility model is:

The desulfurization tower includes a desulfurization tower body and a flue gas channel connected to the flue gas inlet in the middle and lower part of the desulfurization tower body through an elbow; the flue gas channel is provided with a spray device; the flue gas in the inner cavity of the desulfurization tower body Above the entrance position, there are water distribution device, spray device and demister device in sequence from bottom to top.

Preferably, one layer of spraying devices is provided in the flue gas channel, and three layers of spraying devices are provided in the inner cavity of the desulfurization tower body. Both the flue gas channel and the side wall of the desulfurization tower body are provided with observation holes. The top of the desulfurization tower body is provided with a flue gas outlet, the bottom of the desulfurization tower body is provided with a circulating water outlet, and the side wall of the desulfurization tower body is provided with a maintenance channel. The water distribution device is a swirl plate. The demisting device is composed of a baffle and a packing layer.

Working principle: the flue gas flows into the main body of the desulfurization tower through the flue gas channel and the elbow, the flue gas rises, the spray liquid of the spraying device passes through the water distribution device and evenly distributes water to contact and react with the rising flue gas, and finally the flue gas passes through the desulfurization tower. After demisting by the mist device, it is discharged from the flue gas outlet. The spray device and the circulating water outlet are connected with the water pump to form a circulation. The inspection channel is reserved for inspection. The observation hole is made of plexiglass plate, which is convenient for observing the spray effect and debugging.

The desulfurization tower described in the utility model adopts a two-stage four-layer spray device, which can effectively ensure the spray volume. Most of the spray devices distribute water unevenly. Fully contact and respond. The demisting device of this desulfurization tower is composed of baffles and packing layers, which weakens the gas flow rate and enhances the demisting effect. Improved overall processing efficiency.
