Problems solved by technology

At present, the commonly used exhaust gas purification treatment methods are gas circuit detours; or discharge the exhaust gas into the water, through the full contact between the exhaust gas and the water, so that the harmful substances in the exhaust gas can be dissolved in the water to achieve the purpose of purifying the exhaust gas. The resistance of these two methods Larger, the power of the induced draft fan is large, and the energy consumption is large
In addition, filter covers or dust bags are used to filter the inhaled exhaust gas. This method requires regular removal of dirty filter covers or dust bags for cleaning, which is very inconvenient to use; there are also exhaust gas ionization technologies used to purify exhaust gas. Complex structure, high cost, inconvenient maintenance

Embodiment Construction

[0025] The exhaust gas flows into the airtight casing 1 through the air inlet 11, the impeller 6 in the casing 1 atomizes the purification liquid 8, the exhaust gas fully contacts with the atomized purification liquid 8, and the soluble toxic substances in the exhaust gas dissolve in the mist , after the gas flow is decelerated, liquid-gas separation is carried out, and the purified gas is discharged from the gas outlet 13.

[0026] There are two methods of liquid-gas separation, one is that after the gas flow is decelerated, the mist containing toxic substances settles naturally to achieve liquid-gas separation, and the other is to use a gas-liquid separator for liquid-gas separation.

[0027] Such as figure 1 , 2 The shown first embodiment of the exhaust gas purification treatment device of the present invention has a closed housing or box body 1, and the housing or box body 1 is provided with a cavity that separates the inner cavity of the housing or box body 1 into exhaus...

Abstract

A method and apparatus for cleaning waste gas is disclosed. In a sealed casing, there are a partition to divide the internal cavity of said casing into a waste gas cleaning region and a liquid-gas separating region and the blades wheels and airflow guiding plates in the waste gas cleaning region. Its method includes such steps as pumping waste gas in its cleaning region to force the blade wheels to rotate atomizing the cleaning liquid by the blade wheels, contacting the waste gas with the atomized cleaning liquid to dissolved the toxic substances in the cleaning liquid, gas-liquid separating, and exhausting clean gas.

Description

technical field [0001] The present invention relates to a waste gas purification treatment method and device, especially a method for atomizing the purification liquid, and fully contacting the waste gas with the atomized purification liquid, so that the soluble harmful substances in the waste gas can be dissolved in the purification liquid, so as to achieve the purpose of gas purification Waste gas purification treatment method and device. Background technique [0002] The dust produced by coal combustion in industrial production and domestic boilers, the harmful exhaust gas produced by chemical industry production, the harmful exhaust gas produced by incineration of chemical residues and domestic waste, if not purified, the harmful and toxic substances it carries will directly spread in the atmosphere When it enters the human body through the human skin and respiratory tract, it will seriously endanger people's health. At present, the commonly used exhaust gas purificatio...
