Multi-filter core combined flue gas purifying processing device

Abstract

The invention discloses a multi-filter core combined flue gas purifying processing device. The multi-filter core combined flue gas purifying processing device comprises a gas inlet pipe, a purifying tank body, an exhaust pipe, and purifying filter cores; a purifying assembly 1 and a purifying assembly 2 are arranged in the purifying tank body; the purifying assembly 1 and the purifying assembly 2are composed of a plurality of successively arranged purifying filter cores; each purifying filter core is composed of a filter core housing, a support part, a gas exhaust channel, a filter cotton layer, an overflow groove, an adsorption filling material, a gas outlet nozzle, a gas guide tube, an end seal head, a gas collecting housing, a gas filtering layer, and an eduction tube; one end of eachfilter core housing is connected with the corresponding gas collecting housing; the multi-filter core combined flue gas purifying processing device is convenient for filtering treatment of flue gas, is capable of increasing purifying treatment efficiency, absorbing harmful substances such as sulfur dioxide, and dioxin in the air, is convenient for catalytic conversion of carbon monoxide and nitricoxide in flue gas into carbon dioxide and nitrogen dioxide for adsorption and purifying; flue gas is treated using the adsorption filling material, the filter cotton layers, and the gas filtering layers successively, and then is discharged, so that flue gas discharge quality and safety are improved, and environment pollution is avoided.

Description

technical field [0001] The invention relates to the field of smoke treatment equipment, in particular to a smoke purification treatment device combined with multiple filter elements. Background technique [0002] With the rapid development of my country's economy, the energy consumption is increasing day by day, and the air quality is also getting worse day by day. Today, as the requirements for energy conservation, emission reduction and environmental protection continue to increase, natural gas, as a clean energy source with high calorific value, continues to increase its proportion in my country's urban energy consumption structure. At present, most coal-fired boilers in large and medium-sized cities in my country have been changed to gas-fired boilers. For most gas-fired boilers, the exhaust gas temperature is still above 150°C, even as high as 250°C. The gas-fired boiler flue gas contains about 18% water vapor (volume percentage), and there is a large amount of flue g...

Problems solved by technology

The gas-fired boiler flue gas contains about 18% water vapor (volume percentage), and there is a large amount of flue gas sensible heat and water vapor latent heat. polluted the environment

At present, a partition-type waste heat recovery heat exchanger (such as a finned tube economizer) is usually installed at the tail of the boiler, which can only recover part of the sensible heat in the flue gas, and the waste heat recovery efficiency is low, and the flow resistance of the flue gas is relatively large. Great back pressure on the boiler

[0003] In the prior art, a flue gas purification pool is used to absorb the soot in the flue gas through the water in the purification pool, and the heat in the flue gas is recycled by the pipeline. The residence time of the flue gas in the water is short, and the bubbles formed by the flue gas in the water Larger, which makes the flue gas purification effect poor, and the soot left after filtering in the flue gas purification pool also makes the water in the flue gas purification pool turbid, which also affects the separation effect of hot gas and soot, and the flue gas purification pool is long Time work will produce a lot of soot that needs to be cleaned up, and the amount of soot produced by different fuels is different. It is impossible to judge whether it needs to be cleaned from the time. It needs to be stopped for inspection, which is very inconvenient
