Technical field
The utility model relates to dedusting technology field, especially relates to a kind of anti-explosion dust remover.
Background technology
Dust arrester is the equipment that a lot of production industry is equipped with, and its effect is removed after the dust collection at airborne dust place, thus reduces the Dust Capacity entered in air, is that environmental protect pollutes, improves the important environmental protection equipment of air quality.In dust arrester, the mixture of combustible dust and air can be blasted in explosive range as when being lighted or run into incendiary source.If spontaneous combustion after the dust heating deposited, becomes explosion caused incendiary source, causes and once explode; Once explode and dust layer impacted, form dust cloud, cause dust subsequent explosion.Dust explosion will cause security incident problem and economic loss to production.
The explosion-proof technology of current dust arrester has:
Select anti-electrostatic filter cloth, remove the electric charge that filter cloth accumulates, eliminate electrostatic spark.This scheme only eliminates electrostatic spark, also there is other incendiary source hidden danger.
Install explosion relief door, protection dust arrester, such as, the powder coal milling system of metallurgy, electric power, selects sack cleaner to carry out coal powder collection usually.In order to prevent, in collection process, coal dust explosion occurs, several safety anti-explosive holes installed by sack cleaner.But during elongnated building, dust explosion product and the unburned dust cloud of HTHP eject from venting of dust explosion hole, cause subsequent explosion, form new threat to surrounding environment.
CN104190177A discloses a kind of anti-explosion dust remover on December 10th, 2014, this anti-explosion dust remover, have air inlet, dedusting cabin and blower fan, deduster also comprises control circuit and the sensor for monitoring deduster environment state, and sensor is all electrically connected with control circuit with blower fan; When Sensor monitoring exceedes to deduster environment state the deduster environment security settings state set in control circuit, it is out of service that control circuit controls blower fan.Though existing deduster can be solved easily cause blast, the problem that security is poor.But it is out of service because environment worsens easily to cause deduster when needing dedusting, occurs concrete on fire, does not have active suppression device, unfavorable to safety in production.

In order to overcome the defect of prior art, the technical problem that the utility model solves is: provide a kind of anti-explosion dust remover for combustible dust, eliminate potential safety hazard.
In order to solve the problems of the technologies described above, the utility model provides a kind of anti-explosion dust remover, and its technical scheme is: it comprises the deduster body collecting combustible dust, at least has the inerting gas injection system that shower nozzle stretches into described deduster body interior; Detect described deduster body interior CO concentration or/and the detection system of temperature; The control system of described inerting gas injection system is controlled according to the Detection Information of detection system conveying; Described inerting gas injection system comprises at least one inerting gas buffer tank, at least one control valve be communicated with described inerting gas buffer tank by pipeline, at least one check valve be communicated with described control valve by pipeline, at least one is positioned at the inside of described deduster body and the inerting dust prevention sprinkler be communicated with described check valve by pipeline, and the connecting pipe between described control valve with inerting gas buffer tank also has the pipeline be connected with outside inerting gas air supply system.
As further improvement opportunity scheme, the anti-explosion dust remover that the utility model provides, described detection system comprise be arranged on deduster body porch, bottom, middle part and top cable linear temperature sensing device; Be arranged on the CO monitoring device of the outlet of deduster body; Control the controller of described control valve.
As further improvement opportunity scheme, the anti-explosion dust remover that the utility model provides, described inerting dust prevention sprinkler at least two, they are arranged in top or the bottom of deduster body.
As further improvement opportunity scheme, the anti-explosion dust remover that the utility model provides, described inerting gas buffer tank is arranged at the top of deduster body.
On the basis of above-mentioned improvement opportunity scheme, as further improvement opportunity scheme, anti-explosion dust remover provided by the invention, the volume of the inerting gas that described inerting gas buffer tank can eject is not less than 65% of deduster body volume.The inerting gas of needed for deduster inerting in early stage more than 65% stored by inerting gas buffer tank, when inerting gas injection system starts, is conducive to inerting gas and enters rapidly deduster body, for follow-up inerting process is raced against time; Also eliminate because pipe network is long, trouble point is many, the hidden danger that the reaction time is long, the loss of accident can be reduced to lower level.
As further improvement opportunity scheme, the anti-explosion dust remover that the utility model provides, the pipeline be connected with outside inerting gas air supply system is provided with the feedback device of main control valve and described main control valve.
In production process, when detection system detects that the internal temperature of deduster body rises to setting value or when detecting that CO concentration exceedes setting value, Detection Information is delivered to control system by detection system, described control system controls the automatic startup optimization of inerting gas injection system, or staff obtains alarm signal and confirms rear start up system; After inerting gas injection system starts, the inerting dust prevention sprinkler being positioned at the top of deduster body is rapidly to deduster body and sprays into inerting gas; What the inerting dust prevention sprinkler that then control system controls top reduced inerting gas sprays into speed; The inerting dust prevention sprinkler of the bottom of control system control simultaneously sprays into inerting gas in deduster body, makes inerting gas penetrate into dust layer.
When not conflicting, above-mentioned improvement project can be implemented alone or in combination.
On the basis that the utility model discloses, control valve, the quantity of inerting dust prevention sprinkler etc. and position, those skilled in the art rationally can determine according to the volume of deduster and structure, do not need to pay creative work.
In the utility model, inerting gas is larger than atmospheric density, not with the gas of dust generation oxidation reaction, and such as CO
2.
The technical scheme advantage that the utility model provides is as follows: this anti-explosion dust remover arranges the gas inerted extinguishing device of inerting, carries out inactive protect, eliminate potential safety hazard to flammable powder; There is effectiveness of explosion suppression, avoid the combustion explosion of dust, eliminate the harm of subsequent explosion; Carry surge tank, realize spraying soon, make inerting gas be easy to reach the concentration preset, avoid because of outside network fault, fail explosion-proof in time; Considerably increase the security reliability of system; Anti-explosion dust remover carries the gas inerted system of inerting, all accessory devices can integrated design in equipment manufacturer, installation, detection, be conducive to standardization, modularized production, avoid being designed by fire-fighting producer temporarily, on-the-spot to dust arrester transformation, the appearance installing the problems such as inerting gas explosion protection system additional.
