Description
Technical Field
The invention relates to the technical field of dry desulphurization, in particular to a dry desulphurization energy-saving mixed type full-load adjustable system and a control method.
Background
The flue gas generated during combustion of coal, fuel oil and fuel gas contains harmful gases such as sulfur dioxide and nitrogen oxide, and the harmful gases are discharged into the atmosphere, so that acid rain is easily caused, the ecological environment is damaged, the body health of people is influenced, and the environmental protection regulations related to China provide strict control standard requirements for the allowable emission concentration of the sulfur dioxide and the nitrogen oxide in the flue gas.
there are many methods of controlling coal pollution, and they are generally classified into three categories, i.e., pre-combustion desulfurization, in-combustion desulfurization, and post-combustion desulfurization (flue gas desulfurization), with flue gas post-combustion desulfurization being considered to be the most effective way to control SO2 pollution. Currently, there are four major flue gas desulfurization processes that have been applied and continue to be developed: wet limestone/gypsum absorption, dry spray drying purification, in-furnace calcium spray post-humidification water activation (LIFAC), and circulating fluidized bed flue gas purification (CFB-FGD).
The circulating fluidized bed flue gas purification process is characterized in that Ca (OH)2 powder added into a reaction tower is fully contacted and mixed with SO2 and other components in flue gas, such as SO3, HCl, HF and other acidic gases, atomized water sprayed at the inlet of the reaction tower reduces the temperature of the flue gas and ensures the optimal reaction condition, and liquid phase is formed on the surface of Ca (OH)2 particles, SO that the reaction can be fully and rapidly carried out in the reaction tower with acid and alkali amphoteric substances mixed. In the circulating fluidized bed reaction tower, Ca (OH)2 powder, flue gas and sprayed moisture are fully mixed in a fluidized state, and the Ca (OH)2 powder is recycled for multiple times, SO that the Ca (OH)2 amount participating in the reaction in the bed is far greater than the newly added Ca (OH)2 amount, namely the Ca/S ratio of the actual reaction is far greater than the apparent Ca/S ratio, and thus acid gases such as SO2, SO3 and the like can be fully absorbed, and the high-efficiency desulfurization and the high-efficiency utilization of a desulfurizing agent are realized.
however, the existing circulating fluidized bed reaction tower has the following problems: when the load of the reaction tower designed according to the full load of the boiler and the sintering machine is changed, the pressure loss in the reaction tower is changed greatly, the normal operation of a desulfurization system is influenced, and the desulfurization effect is influenced. Even if the low-energy-consumption load-adjustable circulating fluidized bed desulfurizing tower disclosed in the patent No. 201220343448. Under the condition of extreme low load, the pressure of the desulfurization bed is low, the bed pressure requirement of normal operation of a desulfurization system cannot be met, and bed collapse is easily caused.
At present, another measure exists for the problem that the desulfurization system cannot normally operate due to load fluctuation: the clean flue gas circulation method is characterized in that a pipeline is arranged in front of a chimney and connected to an inlet of a reaction tower, and a valve is arranged on the pipeline. No matter the front end load, the clean flue gas and the flue gas to be treated are mixed and then enter the reaction tower by adjusting a valve of a flue gas circulating pipeline, so that the flue gas load in the tower is ensured to be full load, but the scheme has high operation energy consumption and poor economic benefit. Therefore, the prior art does not have a flue gas adjusting device which can ensure the desulfurization efficiency and save energy and reduce consumption.
The Chinese patent with the application number of 201220343448.X discloses a low-energy-consumption load-adjustable circulating fluidized bed desulfurization tower, wherein a bypass pipeline is connected between an air inlet flue and a tower body, so that the load adaptability is good, the pressure loss in the operation of an empty tower is reduced, and the desulfurization is more efficient. As for how to ensure the normal operation of the full-time and full-working-condition desulfurization system and reduce the energy consumption, the technology still has room for improvement.

The flue gas cleaning device also comprises four load adjustable valves 6 and a clean flue gas circulating system adjusting valve 8 of the clean flue gas circulating system, wherein the load adjustable valves 6 and the clean flue gas circulating system adjusting valve 8 are all adjusting valves.

the control method of the dry desulfurization energy-saving hybrid full-load adjustable system specifically comprises the following steps:
When the circulating fluidized bed runs at 0% -40% of full load, the opening size of the regulating valve 8 of the clean flue gas circulating system is determined according to the flue gas flow, so that the pressure loss of the empty tower running is always stabilized at 400-500 Pa, and the normal running of the desulfurization system is ensured;
