Problems solved by technology

However, this purification method often cannot completely remove the acid gas in the mixed gas, and the sprayed alkaline solution is usually discharged directly after rinsing the mixed gas. After long-term use, it is found that the alkaline solution after rinsing is not It is not completely neutral, but also has a certain degree of alkalinity, so it will cause a waste of resources

Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0018] Such as figure 1 As shown, a gas purification device after pyrolysis of biomass fuel includes a square or cylindrical purification box 1, and two partitions 2 are arranged in the purification box 1, and the two partitions 2 clean the inside of the purification box. The space is divided into the first chamber, the second chamber and the third chamber from left to right. The top of the first chamber is provided with an atomizing rotary nozzle 10, and the lower end of the side wall of the first chamber is provided with an air inlet 4. ; The second chamber is provided with a ventilation pipe, and one port of the ventilation pipe communicates with the first chamber through the ventilation hole provided on the partition between the first chamber and the second chamber, and the other port stretches into the second chamber 7-18cm below the liq...

Abstract

A disclosed gas purifying apparatus for pyrolyzed biomass fuel comprises a purification box, two separation plates are arranged in the purification box, and the internal space of the purification box is divided into a first chamber, a second chamber and a third chamber from left to right by the two separation plates; the top of the first chamber is provided with an atomization rotation nozzle; the second chamber is inside provided with a breather pipe, the other end port of the breather pipe stretches into a base solution filling the bottom of the second chamber and has a distance of 7-18 cm to the solution level; and the top of the third chamber is provided with a rotation atomization nozzle. By employing the three chambers, an acidic gas in a mixed gas can be successively purified from left to right, so that the gas purifying apparatus gives play to multiple purification effect, and is capable of relatively thoroughly completely purifying the acidic gas.

Description

technical field [0001] The invention belongs to the technical field of gas purification devices, in particular to a gas purification device after pyrolysis of biomass fuel. Background technique [0002] At present, the high-temperature mixed flue gas produced by pyrolysis furnace or combustion pyrolysis of biomass fuels such as straw and corn stalks is usually directly discharged into the atmosphere. Because there are usually some acid gases such as sulfur dioxide in the mixed flue gas, it will The environment is polluted. Therefore, the mixed flue gas is usually purified by leaching, usually by passing the mixed gas into a leaching tower, and then spraying an alkaline solution on the mixed gas in the tower to neutralize the acidity. Gas, in order to achieve the purpose of removing the acid gas in the mixed gas. However, this purification method often cannot completely remove the acid gas in the mixed gas, and the sprayed alkaline solution is usually discharged directly af...
