Abstract
The invention discloses a carbon dioxide explosion suppressor. The carbon dioxide explosion suppressor comprises a nozzle, a gas ejector pipe, a quick opener and a carbon dioxide storage tank, all of which are sequentially connected. The gas ejector pipe and the quick opener are connected through a flange plate. When an explosive accident happens, the quick opener receives triggering signals and is rapidly opened, liquid carbon dioxide in the carbon dioxide storage tank is sprayed out through the gas ejector pipe and the nozzle, and an explosion suppressing protective screen is formed to suppress explosion flames. Carbon dioxide is adopted as an explosion suppression medium in an explosion suppressor system, the explosion suppressing performance is excellent, the reaction is rapid, and the explosion suppressing duration is long; and the carbon dioxide explosion suppressor has the beneficial effects of being clean, environment-friendly, good in safety and wide in application range.
Description
Technical field
The invention belongs to fuel gas and dust blast prevention and control field, be specifically related to a kind of carbon dioxide explosion suppressor.
Background technology
In imflammable gas, dust market segment, space, industrial market is huge.According to incompletely statistics, current China has more than the business of 60,000 enterprises and is directed to the production of industry imflammable gas dust, stores, transports.In recent years, there occurs a lot of gas, dust explosion accident, cause huge life and property loss.
Existing explosion suppressor mainly adopts water or dry powder as firing-fighting medium, and namely the action by reception triggering signal, sprays water outlet or dry powder is put out a fire.This type of explosion suppressor is primarily present following defect:
A, self-security be poor, such as the dry powder adopted, it is easy to wet and lump, dry powder can be caused not spray or self explosion；
B, speed of action are slow, weak effect；
C, employing dry powder or water are as firing-fighting medium, it is easy to using environment electromechanical equipment to cause damage, and be not easily cleaned.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of datonation-inhibition function superior and cleaning, environmental protection carbon dioxide explosion suppressor.
For reaching above-mentioned purpose, the present invention provides following technical scheme: a kind of carbon dioxide explosion suppressor, including the shower nozzle being sequentially connected with, air jet pipe, opens device and carbon dioxide air accumulator soon, and described air jet pipe is connected by ring flange between device with opening soon.
Further, described device of opening soon is provided with charge valve.
Further, described device of opening soon is provided with Pressure gauge.
Further, described carbon dioxide air accumulator is provided with over-pressure safety device.
Further, described shower nozzle includes the nozzle of several adjustable angle.
The beneficial effects of the present invention is: this explosion suppressor system adopts carbon dioxide as datonation-inhibition medium, datonation-inhibition function is superior, is swift in response and datonation-inhibition persistent period length (can reach more than 2000ms), has cleaning, environmental protection, electromechanical equipment will not be entered, after action, do not need the feature of cleaning；System has overvoltage and under-voltage protection function, can be automatically releasable pressure when internal pressure exceedes limit value, understands auto-cutout when pressure is lower than limit value and reports to the police, being effectively ensured the self-security of system；Can be used for the blast suppressing the place such as imflammable gas, dust to occur, datonation-inhibition reliably, applied widely.
Accompanying drawing explanation
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly, the present invention provides drawings described below to illustrate:
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As it can be seen, the carbon dioxide explosion suppressor in the present embodiment, including the shower nozzle 6 being sequentially connected with, air jet pipe 5, opening device 3 and carbon dioxide air accumulator 1 soon, described air jet pipe 5 is connected by ring flange 4 between device 3 with opening soon.
Concrete, what store in carbon dioxide air accumulator 1 is the liquid carbon dioxide with certain pressure, drives device 3 soon for receiving triggering signal, quickly opens and by carbon dioxide air accumulator 1 and air jet pipe 5 UNICOM；It is arranged on the shower nozzle 6 of air jet pipe 5 end in horn mouth porous water conservancy diversion shape, ensures that the carbon dioxide sprayed out can form good datonation-inhibition barrier.When there being explosion accident to occur, drive device 3 soon and receive triggering signal and open rapidly, by air jet pipe 5 and shower nozzle 6, the liquid carbon dioxide in carbon dioxide air accumulator 1 is sprayed out, form datonation-inhibition barrier, to suppress explosive flame.
This explosion suppressor can not only fast and effeciently suppress detonation propagation, also general flame combustion is also had good inhibition.Adopt carbon dioxide as datonation-inhibition medium, not only there is cleaning, environmental protection, without the advantage of cleaning after using, also there is datonation-inhibition function persistent period length efficient, datonation-inhibition (can reach more than 2000ms), the feature that adjacent electromechanical equipment will not be impacted or damages, applied widely.
As the further improvement of such scheme, described device 3 of opening soon is provided with charge valve 2 and Pressure gauge 7.Charge valve 2 can be used for being filled with liquid carbon dioxide and nitrogen to carbon dioxide air accumulator 1 is internal; pressure size within carbon dioxide air accumulator 1 when Pressure gauge 7 can show inflation and be properly functioning; and when hypotony, carry out open circuit protection and report to the police, to improve the safety of equipment.
As the further improvement of such scheme, described carbon dioxide air accumulator 1 is provided with over-pressure safety device 8；When carbon dioxide air accumulator 1 internal pressure is too high, over-pressure safety device 8 can automatically turn on, and regulates pressure size, to ensure system security.
As the further improvement of such scheme, described shower nozzle 6 includes the nozzle of several adjustable angle.The quantity of shower nozzle 6 top nozzle, planform, perforate mode and sprinkling angle being designed, to realize the adjustment to flow velocity and mist formation shape and control, thus improving the spraying area of carbon dioxide, reaching the purpose of the effectiveness of explosion suppression of raising system.
This explosion suppressor system acting speed is fast, carbon dioxide can be sprayed out rapidly in 8ms after receiving triggering signal, form datonation-inhibition barrier, suppress the blast that imflammable gas/dust explosion place occurs, thus improving the safety of imflammable gas, dusty industrial process, make the people's lives and property from loss.
What finally illustrate is, preferred embodiment above is only in order to illustrate technical scheme and unrestricted, although the present invention being described in detail by above preferred embodiment, but skilled artisan would appreciate that, in the form and details it can be made various change, without departing from claims of the present invention limited range.
