Description
Technical field
The utility model relates to a kind of relative closure device of granule materials storage warehouse, more particularly, relates between a kind of granule materials storage warehouse and the adjacent warehouse, under the static and mobile status of material, guarantees that environmental facies are to the equipment of sealing in the material storage storage.
Background technology
The granule materials storage warehouse of part need to be realized sealing to the material storage storage owing to store the particular characteristics of material, isolated its with the contacting of air, or with realization partition between its and other adjacent warehouse.Such as the storage of some pellet-shaped catalyst needs secluding air, avoids it to lose catalytic activity because of ingress of air suction or oxidation.And for very easily burning with contact with air under the part high temperature, even the granular material of blast is all the more so, typically is exactly the heating desorption additive process of active carbon, activated coke.
And at present to the storage of such granule materials, generally adopt syllogic discontinuous running pattern, realize the sealing to the material storage storage.At first material enters feeding warehouse, after be discharged into surge bunker; Close the surge bunker inlet valve, in surge bunker, be blown into blanket gas and replace gradually air or other non-tight gas gas that enters surge bunker with fill process; Blanket gas is replaced in the surge bunker, opens the surge bunker discharge valve; After material is discharged into the material storage storage in the surge bunker, close the surge bunker discharge valve; All three section operation is finished, and repeats the charging discontinuous operation that above operation realizes the material storage storage.During discharging, the material storage storage at first is discharged into surge bunker with material, closes the surge bunker inlet valve; Open the surge bunker discharge valve, material is discharged into discharge bin or directly draws off; After discharging is finished, close the surge bunker discharge valve; Opening encapsulation gas air inlet valve injects blanket gas discharge air or other non-tight gas gas in surge bunker; After the blanket gas displacement is finished, restart the discharging operation.
Syllogic discontinuous running sealing means can't be realized the continuous flow of material, and the consumption of blanket gas is large.Other gases in the displacement surge bunker need the blanket gas of 4～5 times of surge bunker volumes, even more.And the blanket gas of material storage storage general adopt mostly be unreactable gas, its preparation cost certainly will increase the material storage cost.Step running has caused the process load of material storing warehouse receipt bit time less, also as the process system of a process equipment part, also means increase and the complexity of system and the expansion of scale of energy consumption for the material storage storage.Attached as example take the heating desorption of active carbon, activated coke, the material storage storage is as the desorption consersion unit, in the environment of this sealing, the temperature rising speed of activated coke, active carbon is along with dwindling gradually of the temperature difference between itself and the thermal source reduced, the consuming time of desorption process is extended, and the unit time process load reduces; The temperature that effluxes thermal source raises gradually, and heat is lost in a large number, causes the increase of system energy consumption; Just a plurality of consersion units need to be realized series connection for recovery effluxes thermal source, realize heat recover, the system complex degree increases greatly.
For fear of the deficiency that syllogic discontinuous running sealing means brings, also there is the mode that adopt to prolong the material cross over pipe to realize the continuous movement lower seal material storage storage of material.But this way is only applicable to can significantly increase simultaneously the actual height of material storage warehouse under the not high condition of blanket gas malleation in the material storage storage and pressure, causes construction cost to rise.

Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The relative closure device of granule materials storage warehouse of the present utility model more is applicable to the material storage storage as needing the process system of sealing technology equipment, especially in the material storage storage as process equipment of continuous movement.Take typical active carbon, activated coke desorption activating and regenerating reaction unit as example, the character of active carbon, activated coke has determined that the desorption reaction unit of active carbon, activated coke must be the large-scale storage warehouse formula structure of guaranteeing enough length of the halts of strict secluding air.Must discharge a large amount of pollutantss in the desorption process of active carbon, activated coke, the activating and regenerating process has CO, H
2Produce Deng poisonous and harmful hazardous gas, active carbon, activated coke desorption activating and regenerating reaction unit necessarily require strict sealing, prevent itself and contact with air.The heat conductivility of isoreactivity charcoal, activated coke is not good, and its temperature-rise period is relatively slow; For guaranteeing the structural strength of granular active carbon, activated coke, rate of rise in temperature is also unsuitable too fast; For preventing that violent difference variation from causing the fragmentation of granular active carbon, activated coke to determine that all active carbon, activated coke desorption activating and regenerating reaction unit need enough length of the halts, just mean that also its reactor should be large-scale warehouse form.The temperature conditions of general active carbon, the reaction of activated coke desorption activating and regenerating is also inconsistent, most of pollutantss are namely beginning desorption more than 200 ℃, and the activating and regenerating temperature generally needs more than 400 ℃, and active carbon, activated coke desorption activating and regenerating reaction unit should be the just the most economical rationality of continuous operation mode of rising gradually with material movement direction and temperature.
The effect of the relative closure device of granule materials storage warehouse is to utilize the pressure environment that relatively approaches between adjacent warehouse, guarantee that granule materials storage warehouse pressure is a bit larger tham adjacent warehouse, utilize less difference of pressure to cause blanket gas in adjacent warehouse, to spread, gas in the adjacent warehouse can't move in the material storage storage, thereby realizes the relative closure of granule materials storage warehouse and the continuous movement that material does not affect.
During the interior blanket gas environment malleation of granule materials storage warehouse, by building a slightly low positive pressure environment, difference of pressure is little in its top feeding warehouse or the bottom discharge storehouse, and material cross over pipe length can significantly shorten, and the loss amount of blanket gas significantly reduces; It is equally applicable when the positive pressure pressure of blanket gas is very large.
During the interior blanket gas environment negative pressure of granule materials storage warehouse, by building a slightly low subnormal ambient, equally realize the relative closure to the granule materials storage warehouse in its top feeding warehouse or the bottom discharge storehouse.
With typical 5mm granular activated carbon, activated coke desorption activating and regenerating reaction unit; under the blanket gas environment pressure 8.0KPa condition; material communicating pipe sectional dimension φ 108 * 4mm; length 2000mm is example; if control the weather environment 7.5KPa in the adjacent warehouse; the loss amount of blanket gas is 4.2m3/h only, and active carbon, activated coke desorption activating and regenerating process load can reach 110m3/h, about 80T/h continuously.As adopt the charging of syllogic sealing means, about 440 m3/h of the consumption of blanket gas; Under blanket gas loss amount the same terms, prolonging merely material communicating pipe mode then needs long material communicating pipe of 31m; The relative closure device of granule materials storage warehouse reduces blanket gas loss amount by contrast, has reduced the blanket gas consumption, has shortened material cross over pipe length, realizes simultaneously the continuous movement of material.
