A low-temperature tower flue purification device and its application method

Abstract

The invention relates to a low-temperature tower type flue purification device and an application method thereof. The low-temperature tower type flue purification device mainly comprises a purification tower, a draught fan and an air blower, wherein the draught fan is arranged on the lateral lower side of the purification tower; a plurality of condensation adsorption nets are uniformly mounted in the purification tower with a horizontal included angle of 5-15 degrees; a plurality of liquid spraying holes are formed in one side of the purification tower and are mounted under one fixed side of each condensation adsorption net; the air blower is arranged at the top of the purification tower; a filter screen plate is arranged under an air outlet of the air blower; a liquid spraying opening is arranged above one fixed side of the filter screen plate; and a plurality of groups of heat pump systems which independently and circularly work are arranged at the outer part of the purification tower. The application method comprises the following steps: when air entering from an air inlet of the draught fan collides with the bottommost layer of the condensation adsorption nets, the air in the purification tower is sequentially cooled and condensed; and the air is adsorbed by the condensation adsorption nets layer by layer until the air passing through the filter screen plate reaches emission standards. The low-temperature tower type flue purification device has the beneficial effects that the low-temperature tower type flue purification device has the advantages of novel structure, high purification efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of air purification devices, and in particular relates to a low-temperature tower flue suitable for flue gas discharged from various coal-fired and gas-fired systems, and also suitable for air purification in large public places and waste heat recovery in energy-consuming enterprises Purification device and method of use thereof. Background technique [0002] With the development of industrialization, environmental problems are becoming more and more serious, especially air pollution, which seriously affects people's health; especially a large amount of dust and smoke emitted by industrial production need to be treated and purified in time, in order to make the local environment The air quality has been improved to a certain extent, and people have manufactured different air purification devices; through the air purification devices, the dust, waste gas, toxic and harmful substances produced in production an...

Problems solved by technology

However, when coal is burned, there are still some organic volatiles that cannot be effectively separated, and are discharged into the atmosphere together with the steam. We can already see that the tall chimneys are still emitting smoke, and this device also needs to consume a lot of water. Therefore, using the existing Desulfurization and denitrification devices cannot completely solve the emission of toxic and harmful gases produced by coal combustion; for example, in large industrial and mining enterprises, the air purification devices they use generally use filter screens to remove dust, but the physical method of filtration is used to remove dust. Only the dust particles larger than the mesh diameter of the filter, and the tiny dust and toxic and harmful gas molecules smaller than the mesh diameter are still scattered into the air and cannot be completely removed. Pungent smell, and these pungent substances are often the most harmful to the human body; another example is our air purifier at home, its principle is mainly to release high-voltage static electricity or plasma to absorb dust floating in the air. Harmful gases have no effect, and these electronic devices will produce ionizing radiation, which will cause secondary pollution to the environment, and the device itself consumes a lot of power, and its small scope of application also limits the scope of application

To sum up, the existing air purification devices only process or purify some substances, and the scope of application is limited.
