Ammonia circulating vaporization method and its electric heating carburetor

Abstract

The invention discloses a method for circulating and vaporizing ammonia, which has low energy consumption and is safe and reliable; the method has the processing steps: an external ammonia pump used for storing automobile transmits a certain amount of liquid ammonia into a storage tank body; when the environmental temperature lowers, the liquid ammonia in the storage tank body enters into an electrical heating carburetor through a pipeline for liquid state heating, the liquid ammonia in the electrical heating carburetor is changed into gaseity to be circulated into the storage tank body and then is discharged from an exist of ammonia gas in the storage tank body; at the same time, the invention also discloses the electrical heating carburetor which has ingenious design and safe use, and can reduce the cost; the electrical heating carburetor mainly consists of a box body, a box top, box bottom, the exist of ammonia gas, a platinum resistance, a blowing tube, an ammonia inlet, a water inlet, an overfall gap and a vaporizing disc pipe; the differences line in that the box body is provided with a juice level gauge and is internally equipped with an explosion prevention heating device; the invention can be widely applied to the industries such as iron and steel, powder metallurgy, heat treatment, chemical engineering and the like which transform liquid ammonia into gaseous ammonia.

Description

technical field [0001] The invention relates to a method for supplying raw materials such as ammonia gas purification and ammonia decomposition, which ensures a long-term and stable supply of raw material gas, and in particular relates to an improvement of an ammonia circulation vaporization method. [0002] The invention also relates to the structural improvement of the electric heating vaporizer, which is a special equipment for ammonia circulating vaporization. Background technique [0003] At present, the known ammonia tank process is a non-circulating vaporization system. The tank body directly transports liquid ammonia or gaseous ammonia to the user. The pressure in the tank changes with the change of the ambient temperature. Especially in the northeast of my country, the ambient temperature in winter is below -10 . Tank pressure is "0". It cannot be transported to the subsequent stage for use, and cannot meet the customer's production stoppage demand, resulting in th...

Problems solved by technology

It cannot be transported to the subsequent stage for use, and cannot meet the customer's production stoppage demand, resulting in the customer's production stoppage. In order to solve the production problem, the production unit often pours hot water above 60°C on the tank body or heats it with an open flame. This method consumes a lot of energy and is safe. question

[0004] Although electric heating vaporizers have also been developed on the market, they have the following defects in use: 1. The vaporizer is equipped with 5-15 electric heating tubes, which has a complicated structure and increases costs; Dry burning leads to damage; 3. After the electric heating tube heats the water, the ammonia is vaporized, which is not explosion-proof heating, causing great safety hazards
