Embodiment

[0021] Embodiment: a kind of utilizing CO 2 The technological process of waste gas synthesis of ammonium bicarbonate fertilizer is attached figure 1 Shown: After being further filtered by filter cloth for dust removal and desulfurization, the exhaust gas enters two parallel main decarbonization towers 3 and 4 after being pressurized, and enters from the bottom of the main decarbonization tower from bottom to bottom; The liquefied ammonia released from the tower 10 enters from the main decarbonization towers 3, 4 and the fixed sub-tower 5 by spraying from top to bottom through pipelines, and the CO 2 The gas is fully contacted, and the reaction produces ammonium bicarbonate crystals. Ammonium bicarbonate crystals and remaining ammoniacal liquor are collected in the pool 1 through the pipeline.

[0022] The mixture of ammonium bicarbonate and ammonia water in pool 1 is separated by centrifugation to obtain ammonium bicarbonate crystals and dilute ammonia water, which is collec...

Abstract

The invention discloses a production method for synthesizing an ammonium bicarbonate fertilizer by using CO2 waste gas, which comprises the following steps of: using a process which adopts countercurrent contact to prepare the CO2 waste gas and strong ammonia water after tail gas dedusting and desulfurization into ammonium bicarbonate; reclaiming ammonia gas in the previous process step by using an ammonia reclaiming tower; and discharging remaining tail gas into the atmosphere directly, wherein the ammonia water in the process is concentrated in a reverse osmosis system and is used for recycling again. The greenhouse gas CO2 in the method is treated, so the discharge amount of the greenhouse gas is reduced; the generation of the ammonium bicarbonate fertilizer in the production process has economic benefits; and the production method adopts a reverse osmosis technique to concentrate diluted ammonia water and recycle the strong ammonia water and dialysis water so as to fulfill the aim of zero discharge.

Description

technical field [0001] The invention discloses a method using CO 2 The production method of waste gas synthetic ammonium bicarbonate fertilizer belongs to CO 2 The technical field of waste gas treatment and synthesis of ammonium bicarbonate fertilizer. Background technique [0002] Since the Industrial Revolution, the carbon dioxide and other heat-absorbing greenhouse gases that humans have emitted into the atmosphere have increased year by year, and the greenhouse effect of the atmosphere has also increased. A series of serious problems such as melting, rising sea level, shrinking land area, and abnormal global climate have attracted the attention of countries all over the world. Reducing greenhouse gas emissions has recently become a common goal for all countries. At the World Climate Conference held in Copenhagen in December 2009, countries around the world announced their own carbon dioxide emission reduction plans to reduce greenhouse gas emissions and protect the hum...
