Dual-ash-pump ash slurry pond

Abstract

Disclosed is a dual-ash-pump ash slurry pond. The dual-ash-pump ash slurry pond comprises two branch ash slurry ponds and is provided with an ash slurry diverter valve, an overflowing pipe and a mixed slurry removal pump. The ash slurry diverter valve is provided with two ash slurry conveying pipes and communicated with the branch ash slurry ponds. The mixed slurry removal pump is provided with a lifting shifting mechanism and a mixed slurry nozzle. The lifting shifting mechanism comprises a shifting device and a lifting elevator. The shifting device is arranged between the two branch ash slurry ponds. The lifting elevator is connected with the mixed slurry removal pump. The mixed slurry nozzle is communicated with a high pressure water source or a high pressure gas source. High pressure water or high pressure gas is utilized for mixing coal ash and ash residues accumulated at the bottom of the ash slurry pond into water and pumping and discharging the mixture into the other branch ash slurry pond, an ash removal worker stands on the top of the ash slurry pond, and the bottom of the ash slurry pond can be conveniently cleaned thoroughly by shifting a handle. Accordingly, the dual-ash-pump ash slurry pond is reasonable in structure and convenient to use and the phenomenon that the ash removal worker is injured is avoided.

Description

technical field [0001] The invention belongs to a mortar tank, in particular to a double-ash pump mortar tank. Background technique [0002] Most of the coal ash produced by the combustion of large coal-fired boilers enters the flue along with the flue gas and is collected into the coal ash storage by the dust removal device. The pipeline is transported to the ash settling tank for sedimentation and separation. The coal ash entering the mortar pool contains a lot of ash, which is very hard and often causes damage to the impeller and shaft of the mortar pump. It is relatively simple to lift the mortar pump out of the mortar pool for repair, but the water in the mortar pool must be drained first, and then the coal ash and ash deposited in the mortar pool must be cleaned before the repaired mortar pump can be reinstalled. In the mortar pool. Due to the small area of ​​the mortar pool, the deep bottom and many components on the top, it is necessary to use manpower and use a s...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of low efficiency of cleaning the mortar pool and the easy injury of cleaning personnel in the prior art, the present invention aims to provide a double-ash pump mortar pool, which includes two mortar sub-pools and is equipped with a slurry cleaning pump. The ashes personnel standing on the top of the mortar pool can clean up the coal ash and ash accumulated at the bottom
