Abstract

The invention relates to a liquid ammonia vaporizer and a working method thereof. The liquid ammonia vaporizer comprises a pipe box, a heat exchange section and a vaporization section arranged in sequence from bottom to top; an emptying port is formed in the bottom of the pipe box; a liquid ammonia inlet is formed in the middle part of the pipe box; the heat exchange section consists of pipe plates, a heat exchange pipe and a shell pass cylinder; the heat exchange section is separated from the vaporization section and the pipe box through the upper and lower pipe plates; the heat exchange pipe is vertically arranged in the shell pass cylinder of the heat exchange section, the upper end thereof penetrates through the pipe plate on the upper side to communicate with the vaporization section, and the lower end penetrates through the pipe plate on the lower side to communicate with the pipe box; a steam inlet is formed in one side of the lower part of the shell pass cylinder, and a condensed water outlet is formed in the other side of the upper part; the lower part of the vaporization section is a cone section; and an ammonia gas outlet, a safety valve joint and a pressure gauge joint are arranged at the top. The liquid ammonia vaporizer has the advantages of small equipment size, low weight, good vaporization effect of liquid ammonia and high safety.
