Abstract
The invention provides a fluidization inflaming retarding storage trough (tank) which comprises an ash bucket, a fluidization device, a level gage, a sensor, inert gases (such as N2, CO2 and the like) and the like. The fluidization device is mainly composed of a fluidization pipe and a fluidization board. The fluidization pipe penetrates through the storage trough (tank) so that the inert gases can be introduced to the storage trough (tank), the fluidization board is assembled on the end portion of the fluidization pipe and is placed on the inner wall of the storage trough, the introduced inert gases flow to the storage trough (tank) through a gap in the fluidization board, and the ash bucket is continuously or discontinuously inflated with the inert gases through the fluidization pipe in the fluidization device at certain pressure, so that on one hand, oxygen enriched gases or other harmful gases (methane gas and the like in the food industry) filling the gaps of the materials are expelled, the oxygen content is reduced, the materials are cooled, and therefore spontaneous combustion and even explosion of the materials are completely eradicated; on the other hand, due to the fact that the materials are slowly and evenly stirred by the inert gases, adhesion between the materials and the ash bucket wall is avoided, the material liquidity is improved, and the discharging efficiency is improved.
Description
Technical field
The present invention relates to industrial container equipment, specifically a kind of fire-retardant stock chest (tank) with Fluidizer.
Background technology
At present, Coal Chemical Industry industry, steel industry, food service industry, power field etc. are when storage and reduction agent powder or particle (as coal dust, flour, ground rice, coffee bean powder etc.), and a basic security factor is that material and oxidizer (normally oxygen) is isolated.If Fig. 1 is the structure of current conventional stock chest (tank), this stock chest (tank) is by solid accumulation in bottom, and the gas-insulated oxygen of inerting such as upper square tube nitrogen prevent spontaneous combustion.Under ideal state, inerting gas is (as N
2, CO
2deng) can material and extraneous oxygen is isolated.Yet, in actual use, if poor sealing, or people is in the situation of maloperation, and there are major safety risks in this structure.After equipment quits work, inerting gas stops being filled with stock chest (tank), and now material is also in tank body, if service personnel is opened access door, air enters tank body from access door or poor sealing, causes internal tank oxygen content to exceed standard.And material is owing to being deposited in together always, heat accumulation, causes temperature to arrive firing point (300 ℃ of left and right of coal powder ignition point), and accident will occur like this.Gently material burning, heavy cause exploding.Tank body is conventionally all very huge, once have an accident, consequence is hardly imaginable.
Summary of the invention
The present invention overcomes the deficiencies in the prior art, realizes the not spontaneous combustion of the interior material of stock chest (tank) and does not explode, and accomplish to reduce the friction between material and ash bucket wallboard when discharging, thereby can more shorten bin length, and integral structure is improved.While being applied to food service industry, by stirring material, can also effectively extend effective period of food quality.
For achieving the above object, the fire-retardant stock chest of a kind of fluidisation of the present invention (tank), contains ash bucket, Fluidizer, level-sensing device, sensor, inerting gas (as N
2, CO
2deng) etc.Described Fluidizer inserts stock chest (tank) inside from top, the side of stock chest (tank) respectively.
Further, inerting gas is filled with ash bucket by the fluidisation pipe in Fluidizer continuously or discontinuously with certain pressure, can expel oxygen rich gas and other pernicious gases (methane gas in food industry etc.) that is filled in material gap so on the one hand.Inerting gas stirs stirring slowly, equably by material on the other hand.Due to the cooling and beating action of fluidizing gas, the thermal conduction effect between material and material improves, and the temperature between material is even, and material bulk temperature declines.Two pacing factors that cause material burning have so just been destroyed: temperature and oxygen content, effectively prevent that the spontaneous combustion of material from even exploding.Due to the beating action of inerting gas, eliminated the adhesion of material and grey headwall, significantly improve material fluidity, improved discharging efficiency.Like this, it is less that ash bucket face and horizontal plane angle just can be done, and reaches the object of optimizing structure.
Further, the fire-retardant stock chest of described fluidisation (tank) is installed level-sensing device.When material arrives low material level, low level-sensing device obtains and transmits data to control system, and low Fluidizer is opened; When material reaches middle material level, open low Fluidizer and middle Fluidizer; When reaching high charge level, opens material whole Fluidizers.According to solid accumulation height, open the use amount that corresponding Fluidizer can significantly reduce inerting gas, reach the object that reduces cost.
Optionally, specific aim gas detection sensor can be installed in the fire-retardant stock chest of described fluidisation (tank) top.In Coal Chemical Industry, iron and steel, power industry, normally for oxygen content, detect; In food service industry, the normally detection of methane or other organic gas.When sensor detects corresponding gas concentration and arrives certain warning value, open fluidization system.According to certain gas concentration, carry out open and close fluidization system, can significantly reduce the use amount of inerting gas, reach the object that reduces cost.
Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect:
(1) while limit temperature and oxygen content, the possibility of fundamentally stop material spontaneous combustion, even exploding
(2), although equipment one-time investment improves, and the inerting gas demand in use procedure has but reduced, because the tenure of use of storage tank is conventionally all very long, so on long terms, overall cost does not only increase and has declined on the contrary.
(3) bin length reduces, structure optimization.
(4) discharging efficiency significantly improves.

Below in conjunction with accompanying drawing, introduce the specific embodiment of the fire-retardant stock chest of a kind of fluidisation of the present invention (tank).But it may be noted that enforcement of the present invention is not limited to following embodiment.
Fig. 3 is that the master of the fire-retardant stock chest of fluidisation of the present invention (tank) looks schematic diagram.Casing side, according to basic, normal, high level-sensing device is highly installed, is the error that prevents that material top surface inclination from causing, a level-sensing device is respectively installed at symmetry place.
Fig. 4 is the schematic top plan view of the fire-retardant stock chest of fluidisation of the present invention (tank).Fluidisation pipe inserts pressure container from top, and concrete quantity, spacing, caliber, length, position need, according to actual condition, obtain after calculating.All calculating need meet the related request that GB150 < < pressure container > > HG20584 < < steel pressure vessels for the chemical industry manufacturing technology requires > >.
According to actual condition, fluidisation pipe is divided into low material level Fluidizer, middle material level Fluidizer, high charge level Fluidizer, respectively corresponding three kinds of level-sensing devices.Installation site is staggered installation of with actual condition, as Fig. 4.When material level arrives low material level but less than middle material level, only open low material level Fluidizer and bottom fluidization device, in material level arrives during material level, then material level Fluidizer in opening, when material level arrives high charge level, open whole Fluidizers.Top sensor detects for the sensitive gas concentration of concrete operating mode, when this gas concentration reaches warning value, opens whole fluidization system.Like this, a large amount of nitrogen is constantly filled on relatively original past casing top, can significantly reduce the demand of inerting gas, and the service efficiency of inerting gas is higher.
