An insoluble azo pigment is produced by ejecting a diazo solution and a grounding solution continuously into an ejector such that within the ejector, the diazo solution and grounding solution are mixed with each other and are subjected to a coupling reaction. A production system for the insoluble azo pigment includes the following units (1) to (4): (1) a first feed tank (
2
) for a first fluid selected from the diazo solution or grounding solution, a first flow path (a) for feeding the first fluid to nozzles of an ejector (
1
), and a pump (d) for feeding the first fluid through the first flow path; (2) the ejector (
1
) provided with the nozzles, a suction chamber, a diffuser, and a temperature control device (g); (3) a second feed tank (
3
) for a second fluid, a second flow path (b) for guiding the second fluid into the suction chamber, and a flow control device (e) for controlling a flow rate of the second fluid through the second flowpath (b); and (4) a heat treatment tank (
5
) for subjecting to heat treatment a suspension of the insoluble azo pigment formed by a reaction between the first fluid and the second fluid, and a third flow path (a′) for guiding the suspension from the diffuser to the heat treatment tank.
通过将二氧化溶液和接地溶液连续喷射到喷射器中,使得在喷射器内,二氧化溶液和接地溶液相互混合并进行偶联反应,从而产生一种不溶性偶氮颜料。不溶性偶氮颜料的生产系统包括以下单元(1)至(4):(1)第一个供液罐(2),用于第一个流体,可选择为二氧化溶液或接地溶液,第一个流通路径(a),用于将第一个流体送入喷射器(1)的喷嘴,并且通过第一个流通路径供给第一个流体的泵(d);(2)喷射器(1),具有喷嘴、吸气室、扩散器和温度控制装置(g);(3)第二个供液罐(3),用于第二个流体,第二个流通路径(b),用于将第二个流体引导到吸气室,并且通过第二个流通路径(b)的流量控制装置(e)用于控制第二个流体的流速;(4)热处理罐(5),用于对由第一个流体和第二个流体反应形成的不溶性偶氮颜料的悬浮液进行热处理,以及从扩散器引导悬浮液到热处理罐的第三个流通路径(a′)。
