Abstract
The invention discloses a dry powder extinguishing agent nozzle structure of an explosion suppression device and belongs to a coal mine safety facility. The dry powder extinguishing agent nozzle structure comprises a nozzle fixing pipe, a horizontal nozzle, a set of inclined nozzles and one or more powder inlet ports. The two ends of the nozzle fixing pipe are closed and the middle of the nozzle fixing pipe forms a powder leading cavity. The horizontal nozzle is composed of a horizontal nozzle body and a horizontal nozzle end face end cap. A horizontal nozzle powder outlet channel is formed between the horizontal nozzle end face end cap and the horizontal nozzle body. A first end cap inclined plane is formed on one side, opposite to the horizontal nozzle body, of the horizontal nozzle end face end cap. Each inclined nozzle is composed of an inclined nozzle body and an inclined nozzle end face end cap. An inclined nozzle powder outlet channel is formed between each inclined nozzle end face end cap and each inclined nozzle body. A second end cap inclined plane is formed on one side, opposite to the inclined nozzle body, of each inclined nozzle end face end cap. The powder inlet port is fixed in the other side of the nozzle fixing pipe in the height direction and communicated with the powder leading cavity. The dry powder extinguishing agent nozzle structure of the explosion suppression device has the advantages that the effects that a spreading range is wide, and a tunnel can be closed and isolated are achieved, and the situation that flame spread is caused by gas explosion is avoided.
Description
Technical field
The invention belongs to coalmining safety facility technical field, be specifically related to a kind of powder extinguishing agent nozzle arrangements of explosion suppression device, the flame produced during for the powder extinguishing agent coming from powder extinguishing agent storage tank is ejected into initial by gas explosion, and by fray-out of flame to suppress the expansion of blast and to spread.
Background technology
According to fire-fighting requirements, such as portable dry powder fire extinguisher and handcart-type powder fire extinguisher and corresponding sprinkling fire-distinguishing apparatus must be equipped with at colliery roadway coal mining activity and relevant range thereof, but because these facilities all need manual operation, therefore often miss an opportunity because of a delay, and slow in one's movements, be not enough to fully ensure the security of the lives and property.Firing-fighting medium is that the explosion suppression device of powder extinguishing agent has fast response time, without the need to manual operation with effectiveness of explosion suppression is good etc. that strong point is subject to industry thinks highly of.
Technical information about explosion suppression device is no lack of and is seen in published Chinese patent literature, as utility model patent Authorization Notice No. CN201277056Y(elastic energy storing style gas, dust explosion suppression device), at least there is following shortcoming in this patent formula: one is that nozzle arrangements loses reasonability, cause the extinguishing chemical of ejection to be pencil tendency, namely injection area coverage is limited; Two is mobility shortcomings, installs comparatively bother in field of employment; Three is that tank body cannot according to needing adjustment together with the angle of nozzle.
The gas-producing explosion suppressor that CN201578778U recommends is for CN201277056Y, and the structure of nozzle is comparatively reasonable, is formed horn-like, has achievement for expansion jet face, but does not have its deficiency of adjustable angle system of mobility and tank body.
The nozzle of the gas dust explosion prevention device that CN201211404Y provides is contrary with CN201578778U, can make the ultimate attainment expansion of the coverage rate of spray fire extinguishing agent, but tank body cannot change together with the angle of nozzle and cause using on-the-spot bad adaptability to be its shortcoming.In addition, owing to not there is mobility, such as, often puzzled when installing with moving, namely install and comparatively bother.Structure and the operating principle of the mine automatic powder spraying explosion-suppressing device that CN201401189Y discloses and aforementioned CN201211404Y are similar.
The dust explosion suppression device that invention patent mandate notification number CN102230398B discloses can eliminate the shortcoming of aforementioned patent substantially, and objectively can embody the technique effect described in its manual the 0018th hurdle.
Although the patent being not limited to exemplify above respectively has corresponding strong point, but, it is rationally its logical fraud that the nozzle arrangements of injection powder extinguishing agent is lost, what become gradually to expand from inside to outside by designs of nozzles because these patents have all followed traditional design philosophy is horn-like, the projected area of extinguishing chemical can be expanded theoretically, but due to the particularity of coal mine roadway, when the nozzle of horn mouth shape is when spraying powder extinguishing agent, be difficult to even cannot play by the isolation of whole tunnel or claim closed effect, so gas explosion produce flame easily by means of the air play flowed in tunnel to other position, namely cause and spread.
In view of above-mentioned prior art, be necessary to be improved, the applicant has done long-term and useful exploration for this reason, finally defines technical scheme described below, and is taking through simulated test under strict secrecy provision, and result proves practicable.
