1. An ammonia generator with automatic control and decompression function which characterized in that:

  • the large-diameter cylinder structure is replaced by a small-diameter tube bank structure, the whole structure mainly comprises a lower header pipe (3), a branch pipe bank (2), an upper header pipe (1), a steam collecting pipe (13) and a steam collecting drum (5), an ammonia outlet (7) is arranged at the upper end of the steam collecting drum (5), a light ammonia water outlet (8) is arranged at the lower end of the steam collecting drum (5), a positive-two-pole metal sheet (15) is arranged at the top end of an inner cavity of the steam collecting drum (5), the positive-two-pole metal sheet (15) is respectively communicated with two circuits outside the steam collecting drum (5), a floater (9) capable of floating up and down along with the amount of ammonia water is arranged in the inner cavity of the steam collecting drum (5), a metal sheet (14) is arranged on a top end rod of the floater (9), a needle valve (12) is arranged at the lower end of the floater (5), a throttling valve seat (10) is arranged at the lower end of the steam collecting drum (5), and a pore (11) with a very small aperture is occupied in, when the amount of the dilute ammonia water in the steam collection drum (5) is excessive, the float (9) floats up the needle valve (12) and is separated from the throttle valve seat (10) and the dilute ammonia water flows through the fine holes (11), and a throttling effect is generated, so that the pressure of the flowing dilute ammonia water is reduced to meet the pressure reduction requirement of equipment.
