Problems solved by technology

Due to SiO 2 The relative density of sand particles is much higher than that of water, so the sedimentation speed is fast, so it is easy to deposit in equipment or pipelines, especially in curved pipelines with high resistance, resulting in blockage and affecting the normal operation of the desulfurization device

Embodiment Construction

[0034] As shown in Figure 1, MgO is added to the absorption tower (T101) directly after adding water and ripening to make MgO slurry. Since the air is introduced into the tower for aeration and oxidation, sand particles are not easy to deposit at the bottom of the tower. In addition, a mud pump (P103 ) to send the absorption liquid containing sand particles to the hydrocyclone (S101) to remove the sand particles, the overflow liquid returns to the absorption tower, the bottom liquid flows into the aeration tank (V102), and is further aerated and oxidized with air, and the magnesium sulfite magnesium oxide is Magnesium sulfate is then sent to the clarification tank (V103) by the mud pump (P104) for clarification, the clarified liquid is sent back to the absorption tower by the absorption liquid pump (P105), and the sand slurry at the bottom of the tower is sent to the ash yard by the mud pump (P106).

Abstract

The invention discloses a technology which reduces the jamming in a magnesia method desulfurization device. When desulfurized by coal boiler flue gas magnesia method, the desulfurizer is the magnesia lightly burned by magnesite, which generally contains 5% to 8% of SiO2 sand impurity; in the operation of the desulfurization device, the pipeline is easy to be blocked by the deposition of the sand with large density, thus causing the device to stop; therefore, the design of an anti-blocking structure and the removal of the impurities such as sands, etc. in the desulfurizer are the keys to improve the operation reliability of the device. The invention provides the device and the anti-blocking technology in pipeline design and a process flow which reduces jamming.

Description

technical field [0001] Magnesium oxide slurry desulfurization is a boiler flue gas desulfurization method developed in my country. The desulfurization rate can reach more than 95% at Mg / S=1.05mol / mol, so it is suitable for desulfurization of small and medium-sized boilers. Background technique [0002] Although there will be no blockage of equipment or pipelines due to sulfate scaling in magnesium oxide desulfurization, this is a key factor to ensure its operational reliability. However, the desulfurization agent magnesia is generally made of magnesite by light firing, and generally magnesia contains impurities. According to the national standard GB9354-88, SiO in different grades of magnesia 2 The content is about 5-8%. Due to SiO 2 The relative density of sand particles is much higher than that of water, so the sedimentation speed is fast, so it is easy to deposit in equipment or pipelines, especially in curved pipelines with high resistance, which will cause blockage an...
