Embodiment Construction
[0064] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.
[0065] Such as Figure 1 to Figure 9 Shown, a kind of purification system of ammonia comprises feed tank 1, adsorber 2, rectifying tower 4, condenser 5, transfer tank 6 and finished product tank 3 connected in sequence;
[0066] Further, the purification system also includes a recovery tank;
[0067] The raw material tank 1, the adsorber 2, the finished product tank 3, the rectification tower 4, the condenser 5 and the transfer tank 6 are all provided with pipelines leading to the recovery tank.
[0068] After the raw liquid ammonia is heated in the raw material tank 1 to become ammonia gas, it is transported to the adsorber 2 for adsorption and impurity removal; the ammonia gas from the adsorber 2 is rectified through the rectification tower 4 , enough to remove metal ions, part of the heavy comp...

Abstract
The invention relates to a purifying system for ammonia, which comprises a raw material tank, an absorber, a finished product tank, a rectifying tower and a condenser, wherein the raw material tank, the absorber, the condenser and the finished product tank are connected with each other in turn; a cooling device is arranged in a drum body; a feeding gas inlet pipe and a feeding exhaust pipe are arranged at the top of the drum body; a discharging exhaust pipe and a discharging gas inlet pipe are arranged at the bottom of the drum body; at least two filter screens are arranged, are respectively inclined on the inner walls at the top and bottom of the drum body and can fully encircle the gas ports of the exhaust pipe and the gas inlet pipe; the drum body is filled with a molecular sieve; at least two temperature sensors are arranged on the outer side of the drum body and are arranged on different horizontal positions. The purifying system for ammonia provided by the invention has an excellent absorbing purification effect, is capable of preventing the pipeline from being blocked in the process of absorbing and removing impurities of ammonia, is capable of greatly increasing the working stability and is capable of utilizing the molecular sieve to absorb and purify the ammonia containing impurities.
Description
technical field [0001] The invention relates to the field of ammonia purification, in particular to an ammonia purification system. Background technique [0002] Ammonia, NH3, colorless gas. Has a strong pungent odor. Density 0.7710. The relative density of 0.5971 is easily liquefied into a colorless liquid. It can be liquefied by pressurizing at room temperature (critical temperature 132.4°C, critical pressure 11.2 MPa, or 112.2 atmospheres). Boiling point -33.5°C. It is also easy to be solidified into a snow-like solid. Melting point -77.75°C. Soluble in water, ethanol and ether. It will be decomposed into nitrogen and hydrogen at high temperature, and has a reducing effect. It can be oxidized to nitric oxide in the presence of a catalyst. Used to make liquid nitrogen, ammonia water, nitric acid, ammonium salts and amines, etc. [0003] The purification effect of the existing ammonia gas purification system is poor, and the adsorber is easily blocked, which is no...
