Super-gravity ammonia removal device and ammonia removal method

Abstract

The invention discloses a super-gravity ammonia removal device, comprising a box body, an explosion-proof motor, a liquid circulation loop and a gas circulation loop. The super-gravity ammonia removaldevice provided by the invention utilizes a strong centrifugal force generated by high-speed rotation to enlarge a contact area by means of a liquid film formed by a plastic net, so that gas-liquid relative movement speed is increased, an interphase contact boundary area is greatly increased and is rapidly updated, the mass transfer efficiency of the device is 1 to 3 orders of magnitude greater than that of spray tower equipment, and ammonia gas can be more fully dissolved in water accordingly. The water is recycled, so that the energy consumption of the water is reduced, and the recycling rate of ammonia is increased; furthermore, the super-gravity ammonia removal device has the characteristics of small volume, simple structure, short retention time, uniform micromixing, high mass transfer efficiency and low investment and operating costs. The invention also discloses an ammonia removal method of the super-gravity ammonia removal device.

Description

technical field

[0001] The invention relates to a supergravity ammonia removal device and a use method thereof, which is an ammonia purification treatment device and belongs to the technical field of industrial ammonia treatment equipment. Background technique

[0002] Ammonia is a nitrogen-hydrogen compound. It is a colorless but poisonous gas with a strong pungent smell. It is easily soluble in water. 1 volume of water can dissolve 700 volumes of ammonia, and ammonia is easily dissolved in water. The water reacts chemically to form ammonia monohydrate. Ammonia has a boiling point of -33.5 degrees Celsius and is easy to liquefy. This characteristic is often used in industry, and ammonia is used as a refrigerant. Because ammonia contains nitrogen, it is widely used in the manufacture of soda ash, nitric acid, ammonium salts and fertilizers.

[0003] The explosion limit of ammonia gas is 15.7-27.4%, and its fire hazard belongs to category B item 2. Therefore, ammonia mixed...
