Description
Technical field
The utility model relates to technical field, is specifically related to silo inertia protection system.
Background technology
Now, in order to solve loose coal air storage, contaminated environment, reduces weathering ature of coal.Take silo storing mode.Facts have proved that silo coal storage has little, the no dust pollution of occupation of land, is applicable to the advantages such as various climatic conditions.But because raw coal silo volume reaches tens thousand of cubic meters, belong to the container of relative closure, also brought the new problem of safety anti-explosive, add coal self-characteristic, i.e. oxidation heat liberation spontaneous combustion tendency, silo has " air duct effect " simultaneously.Limited Phase to sealing space in, be unfavorable for heat radiation.Because the coefficient of thermal conductivity of coal is less, heat is slower to surrounding diffusion, heat accumulation makes dump internal temperature raise in dump, in the time that temperature reaches the burning-point of coal, just there is spontaneous combustion in coal, meanwhile, the heat of generation also increases sharply, after temperature, combustable gas concentration and dust concentration reach certain numerical value, will be explosion caused.
Thermal powerplant or the main water of coal plant's inerting system at present, source is wide, price is low, but sprays into after water, and the coal of burning can generate inflammable and explosive water gas with water vapor acting, not only uneconomical but also dangerous.Spray in addition a small amount of water in silo for a large amount of raw coal, can only play the effect of oxidizer, not only can not put out a fire, can accelerate on the contrary the blast of raw coal.
Utility model content
The utility model is according to above-mentioned the deficiencies in the prior art, and a kind of simple in structure, easy to maintenance, silo inertia protection system that inerting effect is good is provided.
In order to achieve the above object, the technical solution adopted in the utility model is:
Silo inertia protection system, comprise silo and be arranged on coal inlet, accumulator unit, pressure purger, ventilation flue and the coal conveyer on silo, described accumulator unit is arranged on a side of silo, and accumulator unit is connected with the ventilation flue on silo by pressure purger; Described silo inside center is provided with hollow ventilation flue, and the surrounding of described silo is equipped with coal inlet, and coal inlet is transported to coal in silo by leading coal pipe; Between described silo inside and coal conveyer, be provided with coal breakage place, described silo inwall is provided with combustible gas sensor, level-sensing device, gas concentration sensor and temperature sensor.
As preferably, described ventilation flue and hollow ventilation flue all have some air gates.
As preferably, described coal inlet is provided with diaphragm seal.
As preferably, described coal breakage place is in the shape of the letter V.
As preferably, the described silo side near accumulator unit is also provided with air regenerating device.
As preferably, described hollow ventilation flue's bottom and top are embedded in silo wall, and are connected with ventilation flue.
As preferably, the gas being filled with in described accumulator unit can be N
2or CO
2.
The utility model beneficial effect is: the utility model is simple in structure, by the method for envelope gas, inflation, ventilation and supporting inerting unit with it, effectively prevents and control the generation of the accident such as spontaneous combustion of coal in silo, and inerting effect is good, safely and fast; In addition, the utility model is also provided with multiple sensors and monitors silo internal environment, can realize local and remote control.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated.
As shown in Figure 1, silo inertia protection system, comprise silo 1 and be arranged on coal inlet 6, accumulator unit 2, pressure purger 3, ventilation flue 8 and the coal conveyer 9 on silo 1, described accumulator unit 2 is arranged on a side of silo 1, and accumulator unit 2 is connected with the ventilation flue 8 on silo 1 by pressure purger 3; Described silo 1 inside center is provided with hollow ventilation flue 7, and the surrounding of described silo 1 is equipped with coal inlet 6, and coal inlet 6 is transported to coal in silo 1 by leading coal pipe 8; Between described silo 1 inside and coal conveyer 9, be provided with coal breakage place 12, described silo 1 inwall is provided with combustible gas sensor 10, level-sensing device 13, gas concentration sensor 14 and temperature sensor 15.
Described ventilation flue 8 and hollow ventilation flue 7 all have some air gates 4; Described coal inlet 6 is provided with diaphragm seal 11; Described coal breakage place 12 is in the shape of the letter V; Described silo 1 side near accumulator unit 2 is also provided with air regenerating device 16; Described hollow ventilation flue's 7 bottom and top are embedded in silo 1 wall, and are connected with ventilation flue 8; The gas being filled with in described accumulator unit 2 can be N
2or CO
2.
The utility model, according to the feature of silo coal storage, arranges accumulator unit 2 in silo 1 one sides, by gas inject silo 1, and dilutes fire gases and the air in silo 1 by ventilation flue 8; At the equal injecting gas in silo 1 bottom and coal breakage place 12, seal coal dropping port; Air regenerating device 16 is also installed on silo 1, in the time of the imflammable gas excessive concentration such as the interior fire gases of silo 1 (CO, CH4), oxygen, smog, imflammable gas has been extracted out, refilled gas.
Such scheme is preferred embodiment of the utility model, but is not changing under spiritual background of the present utility model, and any improvement of doing, within all dropping on protection domain of the present utility model.
