Problems solved by technology

[0002] The waste gas produced by the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc. Some of the impurities and gases can be recovered by dissolving in water, but after dissolving in water, the liquid is discharged It will cause water pollution again, which is inconvenient for subsequent treatment, and will lead to complicated procedures and increase treatment costs

Embodiment 1

[0025] Such as figure 1 As shown, a chemical tail gas deodorization equipment includes a high-pressure dissolved air pump 101 connected to chemical equipment through pipelines;

[0026] The high-pressure dissolved air pump 101 is connected to the airtight water tank 102 through a pipeline, the output end of the airtight water tank 102 is provided with a jet pump 103, and the output end of the jet pump 103 is connected to the gas-liquid separation chamber 104. A gas-liquid separator is arranged in the gas-liquid separation chamber 104;

[0027] A liquid storage tank 105 is arranged at the lower end of the gas-liquid separation chamber 104, and a one-way valve connected with the desulfurization chamber 106 is arranged at the upper end of the gas-liquid separation chamber 104;

[0028] The desulfurization chamber 106 is provided with an adsorption layer 107, the adsorption layer 107 is a honeycomb structure, the surface of the adsorption layer 107 is provided with a calcified de...

Embodiment 2

[0035] A method for deodorizing chemical tail gas, comprising the following steps:

[0036] S1: Use the high-pressure dissolved air pump 101 to pressurize the chemical tail gas into the closed water tank 102, so that the ammonia and air in the chemical tail gas are pressurized and transported to the closed water tank 102, and a large amount of air squeezes the ammonia dissolved in the water, and the water absorbs it part of sulfur dioxide;

[0037] S2: Start the jet pump 103 to atomize the ammonia dissolved in water and spray it out at a high speed, so that ammonia enters the gas-liquid separation chamber 104 and is separated from water through the gas-liquid separator, and the remaining sulfur dioxide and ammonia enter the desulfurization chamber through the gas-liquid separator 106;

[0038] S3: Start the air pump to generate negative pressure in the desulfurization chamber 106, so that the gas accelerates through the desulfurization chamber 106. After the sulfur dioxide is...

Description

technical field [0001] The invention relates to a chemical tail gas deodorization device and a deodorization method, in particular to the tail gas treatment in the nitrogen fertilizer industry. Background technique [0002] The exhaust gas produced by the nitrogen fertilizer industry mainly contains nitrogen oxides, urea dust, carbon monoxide, ammonia, sulfur dioxide, methane, etc. Some of the impurities and gases can be recovered by dissolving in water, but after dissolving in water, the liquid is discharged It will cause water pollution again, which is inconvenient for follow-up treatment, and leads to complicated procedures and increased treatment costs. Contents of the invention [0003] The purpose of the present invention is to provide a chemical tail gas deodorization equipment and deodorization method, which can simplify the equipment and realize the separation of ammonia and sulfur. [0004] The present invention is realized through the following technical soluti...
