Pneumatic calcium hydroxide conveying system

Abstract

The invention discloses apneumatic calcium hydroxide conveying system. The pneumatic calcium hydroxide conveying system comprises a feeding device, an air source device, an air conveying pipe, a feed bin and a full-automatic control room, wherein the feeding device comprises a discharging pipe and a bin pump which are arranged below a calcium hydroxide producing system; a feeding valve is arranged on the bin pump; an intake pipe and a vent pipe are connected to the bottom of the bin pump; the air source device comprises an air storage tank connected with the intake pipe and a pneumatic conveying air supply system connected to the air storage tank; the air conveying pipe is connected with the vent pipe through a discharging valve; the feed bin comprises a plurality of terminal bins connected to the air conveying pipe; and automatic dust collecting systems and returning valves are arranged on the terminal bins. The pneumatic calcium hydroxide conveying system can automatically and circularly convey a material to the terminal bins at intervals or in a skipping way, is safe and reliable and economical and practical, and effectively solves the problem that the pipes are easily blocked.

Description

technical field [0001] The invention belongs to the technical field of pneumatic conveying systems, and in particular relates to a calcium hydroxide pneumatic conveying system. Background technique [0002] Pneumatic conveying equipment is widely used because it has good dust-proof effect, is easy to realize mechanization and automation, can reduce labor intensity and save manpower. Calcium hydroxide is used as a desulfurization agent in desulfurization systems. In wet and dry desulfurization systems, many pneumatic conveying equipment is used to transport desulfurization agents. [0003] Calcium hydroxide is a white powdery solid. The distribution of calcium hydroxide particles is relatively discrete, and the velocity gradient of the suspended powder is large. It is easy to corrode, easy to block, and easy to be damp. The system generally has problems such as severe wear, frequent jamming of valves, and frequent blockage of pipes. Contents of the invention [0004] In o...
