Problems solved by technology

[0002]At present, some power plants have newly added desulfurization and denitrification systems through environmental protection transformation, but the slaked lime bins generally do not have an external discharge system. After the heating unit is shut down, the slaked lime The remaining slaked lime in the silo is stored in the slaked lime silo for a long time and cannot be discharged
During the storage process, continuous fluidization work is required to prevent hardening and blockage, resulting in frequent start and stop of desulfurization equipment and a large consumption of plant power

Abstract

The invention provides a boiler desulfurization slaked lime bin discharge system, which comprises a lime bin, wherein the lime bin comprises a shell, a lime inlet and a lime discharge port, the shell forms the overall shape of the lime bin, the lime inlet is located at the upper end of the lime bin, the lime discharge port is located at the lower end of the lime bin, and the ash discharge port is connected with a one-way valve; an anti-blocking mechanism which comprises a fan and a first pipeline, wherein one end of the first pipeline is fixedly connected with an air outlet of the fan, and the other end of the first pipeline is communicated with the one-way valve; and the one-way valve, wherein a feeding hole is formed in the upper end of the one-way valve, and a hose is arranged at the lower end of the one-way valve. The detachable one-way valve is arranged at the lower end of the lime bin, and after the heat supply unit stops running in summer, residual slaked lime in the lime bin can be discharged in time. The hardening and blocking of slaked lime are avoided, auxiliary power is saved, the service life of equipment is prolonged, and the operation risk of operators is reduced.

Description

technical field [0001] The invention relates to the technical field of boiler desulfurization, in particular to a boiler desulfurization slaked lime bin discharge system. Background technique [0002] At present, some power plants have newly added desulfurization and denitrification systems through environmental protection transformation, but the slaked lime bins generally do not have an external discharge system. After the heating unit is shut down, the remaining slaked lime in the slaked lime bin is stored in the slaked lime bin for a long time and cannot be discharged. During the storage process, continuous fluidization work is required to prevent hardening and clogging, resulting in frequent start and stop of desulfurization equipment, which consumes a lot of plant power. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omis...
