The present invention relates to A lock hopper () provided with air-tight hoppers (A, B) arranged side by side with entrance valves (A, B) arranged above the air-tight hoppers (A, B) and exit valves (A, B) arranged below the air-tight hoppers (A, B). The lock hopper () performs control which alternately repeats the following states: a state in which granular substances in an upper system are placed in one of the hoppers and gas is supplied into the other hopper to discharge granular substances from the inside of the other hopper to a lower system and a state in which the granular substances in the upper system are placed in the other hopper and gas is supplied to said hopper to discharge granular substances from the inside of said hopper to the lower system. Also provided is a method of transferring granular substances in an upper system to a lower system by using above-described lock hopper, wherein gas having a volume corresponding to the volume of at least the granular substances to be discharged to the lower system is supplied to a hopper in a state in which the granular substances are being discharged from the hopper to the lower system.

Lock hopper

Adsorbent dust can be recovered while spraying is prevented. An apparatus is provided with a desulfurization-denitration tower body and an adsorbent discharging device. An entrance louver and an exit louver are provided for forming a packed moving bed of an adsorbent that moves downward inside the tower body, the apparatus has a throttle portion provided with a side panel that is inclined so that a spacing gradually decreases toward a discharging device, the throttle portion being provided between the tower body and the discharging device, and first partitions are provided inside the throttle portion. A second partition extending along the incline direction of the side panel is provided at a predetermined distance from the bottom end of the exit louver above the side panel, and a gap is provided between the bottom end part of the exit louver and the side panel of the throttle portion.

Desulfurization-denitration apparatus for exhaust gas

An exhaust gas dry treatment device comprises an adsorption tower having: a box-shaped tower body; a plurality of reaction chambers have moving beds therein; a plurality of vertical partition plates which sequentially close between the end parts of the plurality of reaction chambers and between the end parts of the reaction chambers and the inner wall of the tower; an exhaust gas supply port allowing the inside of an inlet side wind box space which is formed in the tower body between the front tower wall and the reaction chamber end part to communicate with the inside of an exhaust gas supply duct; and an exhaust gas discharge port allowing the inside of an outlet side wind box space which is formed in the tower body between the rear tower wall and the reaction chamber end part to communicate with the inside of an exhaust gas discharge duct.

Adsorption tower of dry exhaust gas treatment device

Fixed amount discharging equipment for simultaneously discharging a particulate body from a plurality of containers containing the particulate body, comprising a casing to the interior of which is provided a belt conveyor and having a particulate body discharge hole below the carrying direction end of the belt conveyor, and a plurality of supply arranged in the carrying direction of the belt conveyor and passing through the casing, lower ends thereof penetrating into the casing and being arranged above the belt of the belt conveyor, the lower ends of the supply pipes being such that the downstream sides thereof in the belt carrying direction have notches of a predetermined length from the end faces upward.

Equipment for discharging a fixed amount of a particulate body

An exhaust-gas treating apparatus, which includes an adsorption tower for removing various harmful substances in an exhaust gas using an adsorbent, a regeneration tower for releasing adsorbed substances from the adsorbent, a first transfer passage for transferring the adsorbent from the adsorption tower to the regeneration tower, a second transfer passage for transferring the adsorbent from the regeneration tower to the adsorption tower, a lock hopper connected to one end of the regeneration tower on a higher differential pressure side of a first differential pressure between an inside of the regeneration tower and an inside of the first transfer passage and a second differential pressure between the inside of the regeneration tower and an inside of the second transfer passage to thereby secure gas-tightness, a sealing unit connected to the other end of the regeneration tower on a lower differential pressure side to thereby secure gas-tightness, and an adjusting unit for maintaining the differential pressure in the sealing unit within a fixed range.

Dry exhaust-gas treating apparatus

A regeneration tower including a regeneration tower main body having a long trunk, and desorbed gas discharge passages through which a desorbed gas is discharged. The regeneration tower main body is configured so that a heating unit that heats an adsorbent, a separation part that separates desorbable substances as a desorbed gas from the heated adsorbent, and a cooling unit that cools the adsorbent from which the desorbable substances have been desorbed by heating are communicatively disposed in one direction and the heating unit and the cooling unit have approximately the same sectional outer diameter.
