Description
Technical field
The utility model belongs to gas recovery techniques field in the Chemical Manufacture, particularly a kind of Device to make dilute nitric acid by Nitrogen oxides absorb meythod that is applied to the rare nitric acid of nox adsorption system.
Background technology
Nitrogen oxide reclaims, and is the needs of environmental protection, also saves material simultaneously.In produces tartronic, utilize nitric acid oxidation method, the NO gas of generation, the method for absorption has multiple, there is water to absorb and the alkali lye absorption, water absorbs through after the absorption of 2-3 level, still has a spot of nitrogen oxide not to be absorbed, and enters atmosphere, cause air pollution, directly absorb with alkali lye, the cost height, nitric acid dosage increases.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of these two kinds of absorption patterns that make full use of effectively to solve above problem.
The purpose of this utility model is achieved in that and comprises the one-level jet pump that has the nitrogen oxide import, the one-level basin of one-level jet pump bottom, be provided with the one-level circulating pump between one-level jet pump and one-level basin; Two-level absorption tower and one-level jet pump and one-level basin are connected, and are provided with the secondary basin below two-level absorption tower, are provided with the secondary circulating pump between two-level absorption tower and the secondary basin; Three grades of absorption towers and two-level absorption tower are connected, and are provided with three grades of basins below three grades of absorption towers, are provided with three grades of circulating pumps between three grades of absorption towers and three grades of basins; Level Four absorption tower and three grades of absorption towers are connected, and are provided with the level Four basin below the level Four absorption tower, are provided with the level Four circulating pump between level Four absorption tower and level Four basin; Pyatyi jet pump and level Four absorption tower are connected; Below the Pyatyi jet pump, be provided with the Pyatyi basin; Pyatyi basin and chimney are connected; Be provided with the Pyatyi circulating pump between Pyatyi jet pump and the Pyatyi basin.
The utility model adopts the principle of multistage absorption, at first the first order is utilized corrosion-resistant water-jet pump, the nitrogen oxide water that Workshop Production is discharged absorbs, the first order does not have absorbed gas to enter the bottom of two-level absorption tower, with water that enters from top cat head or diluted acid, fully contact on the inner-tower filling material surface and absorb, for entering three grades of absorption towers, the gas that absorbs absorbs, the unabsorbed gas content of third level cat head is very low, enters the level Four absorption tower and absorbs with alkali lye.After alkali lye absorbs, in order further fully to absorb, utilize water to spray vacuum absorption adding one-level, simultaneously also for front secondary, three grades, level Four absorbs that vacuum is provided.Therefore the utlity model has good absorbing effect, cost advantage low, free from environmental pollution.
