Problems solved by technology

Although it has a broad market prospect, it has not achieved localization
In addition to the technical difficulty of the project and the high risk of product development, environmental protection issues have always been the bottleneck restricting the development of the project
Because the production process of methionine will produce two highly toxic substances - methyl mercaptan and acrolein, these two gases will emit an unbearable pungent odor, which will inevitably affect the production operation and production of workers in the factory area. The life of residents around the factory has a great impact
At present, the incineration treatment process of methionine waste liquid and waste gas is still blank in China, and there is no mature process

Embodiment 1

[0028] Such as figure 1 Shown is a pollution-free treatment device for treating organic waste liquid and waste gas containing sulfur and salt in the production process of methionine. The device includes an incinerator 10, a sulfur-containing organic waste gas supply system, a sulfur-containing and salt-containing organic waste liquid supply system, a fuel gas supply system and a combustion-supporting air supply system respectively connected to the inlet of the incinerator 10, and connected to the outlet of the incinerator 10 The waste heat recovery system, the desulfurization system connected with the waste heat recovery system.

[0029] The fuel gas supply system includes a fuel gas supply pipeline 3 under the condition of low calorific value waste gas and liquid. The fuel gas supply pipeline 3 is connected to the fuel gas inlet of the burner of the incinerator 10, that is, the fuel gas is directly sent into the incinerator for accompanying combustion, so as to provide fuel....

Embodiment 2

[0040] Such as figure 1 As shown, a pollution-free treatment method for treating sulfur-containing and salt-containing organic waste liquid and waste gas in the production process of methionine according to the present invention comprises the following steps:

[0041] (a) Transport the sulfur-containing organic waste gas to the combustion chamber of the incinerator 10 through the sulfur-containing organic waste gas supply system, and transport the sulfur-containing and salt-containing waste liquid to the combustion chamber of the incinerator 10 through the sulfur-containing and salt-containing organic waste liquid supply system; Natural gas enters the combustion chamber of the incinerator 10 through the fuel gas supply system; air is transported to the combustion chamber of the incinerator 10 through the combustion-supporting air supply system; °C or 1250 °C), the above-mentioned waste liquid and waste gas are pyrolyzed and oxidized in the incinerator 10 to produce 2 O.CO 2 ...

Abstract

The invention provides a sulfur-containing and salt-containing organic waste liquid and waste gas pollution-free treatment device and method. An inlet of an incinerator in the device is connected with a sulfur-containing organic waste gas supply system, a sulfur-containing and salt-containing organic waste liquid supply system, a fuel gas supply system and a combustion-supporting air supply system respectively; an outlet of the incinerator is connected with an after heat recovery system; and the after heat recovery system is connected with a desulfurization system. The method comprises the following steps of: conveying sulfur-containing organic waste gas, sulfur-containing and salt-containing waste liquid, natural gas and air into a combustion chamber of the incinerator; feeding produced high-temperature flue gas into a waste heat boiler and an economizer in sequence; and feeding the flue gas into a cooling, concentrating and absorbing tower and a washing and absorbing tower in sequence. According to the device and the method disclosed by the invention, the sulfur-containing and salt-containing organic waste liquid and the sulfur-containing and salt-containing organic waste gas produced during production of methionine are simultaneously fed into the combustion chamber of the incinerator in two paths, and high-temperature decomposition of the sulfur-containing and salt-containing organic waste liquid and the sulfur-containing and salt-containing organic waste gas in the combustion chamber is realized, so that the requirement of environmental friendliness is met, a fuel is also saved, and double effects of energy conservation and pollution-free treatment are achieved.

Description

technical field [0001] The invention relates to a process for the pollution-free treatment of sulfur-containing and salt-containing organic waste liquid and waste gas produced in the production process of methionine, and specifically relates to an incineration desulfurization treatment device for sulfur-containing and salt-containing organic waste liquid and waste gas produced in the production process of methionine. method. Background technique [0002] Methionine, also known as methionine, is widely used in feed industry, pharmaceutical industry, health care industry and food industry, and can also be used in biochemical research, photographic technology, cosmetics, spices and other fields. As an important amino acid species, it is an indispensable nutrient in compound feed. Although it has a broad market prospect, it has not achieved localization. In addition to the technical difficulty of the project and the high risk of product development, environmental protection is...
