Problems solved by technology

Under such high temperature conditions, conventional desulfurization equipment cannot solve the damage caused by high temperature and high temperature corrosion at all. In petroleum coke calcination enterprises that have installed desulfurization equipment, even if equipment made of expensive materials such as stainless steel is used, the service life is rarely more than half a year. Above, more than one month

Embodiment Construction

[0018] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0019] Such as Figure 1~2 As shown, the present invention includes: a flue and a flue gas inlet 1, a flue gas inlet 1 is provided at the lower end of the flue, and the flue is composed of a temperature-resistant enamel section 2 at the lower end and a common section 3 at the upper end.

[0020] In this embodiment, the length of the temperature-resistant enamel section 2 accounts for 1 / 2 of the total length of the flue.

[0021] An acid outlet 4 is provided at the bottom end of the temperature-resistant enamel section 2.

[0022] The thickness of the temperature-resistant enamel section 2 in this embodiment is 28 mm. The thickness of the temperature-resistant enamel layer is 1.0mm.

[0023] The upper end of the ordinary section 3 is provided with a spray head 5.

[0024] The flue gas enters the flue through the flue gas inlet 1, and after the cooling process ...

Abstract

The invention relates to high-temperature corrosion-resistant equipment for a flue gas desulfurization system, and belongs to the field of environmental protection equipment in the chemical production process. The high-temperature corrosion-resistant equipment comprises a flue and a flue gas inlet, wherein the flue gas inlet is formed in the lower end of the flue; and the flue consists of a temperature-resistant enamel section at the lower end and a common section at the upper end. Compared with the existing generally-adopted conventional desulfurization facility, the equipment provided by the invention has the beneficial effects that after the equipment is practically used in the desulfurization process, the high-temperature corrosion resistance of the equipment is greatly improved, the service life of the equipment is also greatly prolonged, and the practical service life is above 20 times of that of the existing common equipment.

Description

Technical field [0001] The invention relates to a high-temperature corrosion-resistant equipment used in a flue gas desulfurization system, and belongs to the field of environmental protection equipment used in a chemical production process. Background technique [0002] In the carbon industry, the flue gas emitted during the calcination process of petroleum coke contains a large amount of pollutants such as sulfur dioxide. Compared with the thermal power industry and small and medium-sized coal-fired boilers, it also causes serious pollution to the atmosphere. At present, in order to solve this kind of pollution, the methods commonly used in thermal power plants and small and medium-sized coal-fired boilers are the traditional two-alkali method, ammonia method, and limestone-gypsum method. The use of these methods can effectively reduce the emission concentration of sulfur dioxide in the flue gas, thereby effectively reducing the pollution to the atmospheric environment. [0003]...
