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 the coalmining safety facility technical field, be specifically related to a kind of powder extinguishing agent nozzle arrangements of explosion suppression device, the powder extinguishing agent that is used for coming from the powder extinguishing agent storage tank is ejected into the flame place that produces when initial by gas explosion, and with fray-out of flame with the expansion that suppresses blast with spread.
Background technology
According to the fire-fighting requirement, must be equipped with such as portable dry powder fire extinguisher and handcart-type powder fire extinguisher and corresponding sprinkling fire-distinguishing apparatus at colliery roadway coal mining activity and relevant range thereof, but because these facilities all need manual operation, therefore tend to miss an opportunity because of a delay, and slow in one's movements, be not enough to the security of the lives and property is fully ensured.Firing-fighting medium be the explosion suppression device of powder extinguishing agent have response speed fast, need not manual operation and datonation-inhibition strong point such as effective and be subjected to industry and think highly of.
Be no lack of in disclosed Chinese patent literature about the technical information of explosion suppression device and be seen in, as the novel license notification number of practicality CN201277056Y(elastic energy storing style gas, dust explosion explosion suppression device), there is following shortcoming at least in this patent scheme: the one, and nozzle arrangements is lost reasonability, cause the extinguishing chemical of ejection to be the pencil tendency, it is limited namely to spray area coverage; The 2nd, the mobility shortcoming is installed comparatively trouble in the field of employment; The 3rd, tank body can't be according to needing adjustment together with the angle of nozzle.
The air-generating explosion suppressor that CN201578778U recommends is for CN201277056Y, and structure of nozzle is comparatively reasonable, forms horn-likely, for enlarging jet face achievement is arranged, but to put in order property be its deficiency to the adjustable angle that does not have mobility and a tank body.
The nozzle of fuel gas and dust that CN201211404Y provides blast explosion suppression device is opposite with CN201578778U, can make the ultimate attainment expansion of coverage rate of spray fire extinguishing agent, yet tank body can't change and cause using the bad adaptability at scene together with the angle of nozzle is its shortcoming.In addition, owing to do not have mobility, for example in the time will installing, tend to be puzzled with moving, comparatively trouble namely is installed.The mining automatic powder spraying explosion suppression device that CN201401189Y discloses and structure and the operating principle of aforementioned CN201211404Y are similar.
The dust explosion explosion suppression device that invention patent mandate notification number CN102230398B discloses can be eliminated the shortcoming of aforementioned patent basically, and objectively can embody the technique effect described in its manual the 0018th hurdle.
Though the patent that is not limited to exemplify above respectively has corresponding strong point, but, it rationally is its logical fraud that the nozzle arrangements of injection powder extinguishing agent is lost, because these patents have all followed traditional design philosophy designs of nozzles is become expand gradually from inside to outside horn-like, can expand the projected area of extinguishing chemical theoretically, but because the particularity of coal mine roadway, when the nozzle of horn mouth shape when spraying powder extinguishing agent, the effect that is difficult to even can't plays the whole tunnel isolation or claim to seal, so the flame that gas explosion produces arrives other position by means of flow air play in the tunnel easily, namely causes and spreads.
In view of above-mentioned prior art, be necessary to be improved, the applicant has done long-term and useful exploration for this reason, has formed technical scheme described below finally, and is taking under the strict secrecy provision through simulated test, and it is practicable that the result proves.
