Problems solved by technology
However, in the traditional method, the nozzle is mainly made of iron material. During combustion, iron easily reacts with oxygen to cause the nozzle to be easily damaged, and the maintenance cost is high. In addition, during the combustion process, the fire in the incinerator is easy to enter inside the nozzle to burn out the nozzle and its associated components

Embodiment Construction
[0021] see Figure 1-3 , The present invention discloses a novel incinerator device for producing hydrosulfite, which includes an incinerator body 10 , an oxygen delivery pipe 11 and a nozzle 12 .
[0022] The incinerator body 10 is provided with a combustion cavity 101 for combustion.
[0023] One end of the oxygen delivery pipe 11 is exposed outside the side wall of the incinerator body 10 .
[0024] The nozzle 12 is arranged at the other end of the oxygen delivery pipe 11 .
[0025] In this embodiment, one end of the combustion cavity 101 of the incinerator body 10 is filled with a high-temperature-resistant high-alumina brick material layer 102, wherein the other end of the oxygen delivery pipe 11 is accommodated in the high-alumina brick material layer 102, and the nozzle 12 It is accommodated in the combustion cavity 101 and exposed outside the high alumina brick material layer 102 .
[0026] Preferably, the nozzle 12 is constructed of a ceramic material. It should b...

The invention discloses a novel incinerator device for producing sodium hydrosulfite, which comprises an incinerator body provided with a combustion cavity for combustion; one end of the oxygen conveying pipe is exposed out of one side wall of the incinerator body; the nozzle is arranged at the other end of the oxygen conveying pipe; one end of a combustion cavity of the incinerator body is filled with a high-temperature-resistant high-alumina brick material layer, the other end of the oxygen conveying pipe is contained in the high-alumina brick material layer, the nozzle is contained in the combustion cavity and exposed out of the high-alumina brick material layer, and the nozzle is made of ceramic materials and is composed of a cylindrical pipe body. And the outer wall of the pipe body is provided with an inward concave groove. By means of the mode, the nozzle of the novel incinerator device for producing the sodium hydrosulfite is made of the ceramic materials, is resistant to high temperature and is not prone to damage, the groove which is concave inwards is formed in the outer wall of the nozzle, reverse burning of fire in an incinerator can be prevented, and the phenomenon that the nozzle and related devices are burnt out is eradicated.
Description
technical field [0001] The invention relates to the technical field of sodium hydrosulfite, in particular to a novel incinerator device for producing hydrosulfite. Background technique [0002] Sodium dithionite, also known as hydrosulfite, is a white sandy crystal or light yellow powder chemical product, with a melting point of 300°C (decomposition), an ignition temperature of 250°C, insoluble in ethanol, soluble in sodium hydroxide solution, and in contact with water It reacts strongly and burns. In terms of various substances, it can also be used for food bleaching, such as gelatin, sucrose, candied fruit, and bleaching of soap, animal (vegetable) oil, bambooware, and china clay. It can also be used in organic synthesis, such as reducing agent or bleaching agent in the production of dyes and pharmaceuticals. Sodium dithionite is the most suitable bleaching agent for wood pulp and papermaking. The wide range of uses makes the production of hydrosulfite continuously increas...
