Description
Technical field
The present invention relates to extinguishing device, especially relate to a kind of constant-pressure storage type high-pressure carbon dioxide extinguishing device that has built-in evaporator.
Background technology
Because alkyl halide is to the destruction of atmospheric ozone layer, more and more stricter restriction has been made to the use of alkyl halide by international community, and carbon dioxide is the first-selected product that replaces alkyl halide.CO has passed through applying of many decades abroad, has experienced a large amount of fire tests, is Application and Development gas extinguishing system the earliest.In China, though the high and low pressure CO has passed through application for many years, because high-pressure carbon dioxide fire extinguishing system extinguishing chemical is to store at normal temperatures, cause that to fill density lower, so the used steel cylinder of bunkerage is many, floor space is big, cost is also high, and biggest advantage is the initial pressure height when spurting, and reaches 5.17MPa, the fed distance of extinguishing chemical is long, and it is stifled to be difficult for producing ice during agent application; For low pressure carbon dioxide fire extinguishing systems,, and adopt hold-up vessel to store extinguishing chemical because the loading amount coefficient is big, its floor space is little, and cost is also lower, and maximum problem is that the initial pressure when spurting is low, have only 2.07MPa, fed distance is short, and it is stifled easily to produce ice during agent application.Chinese patent 200720078378.9, a kind of constant-pressure storage type high-pressure carbon dioxide extinguishing device is disclosed, its evaporator assemblies can take apart in hold-up vessel, it is mounted in the flange place of hold-up vessel manhole, and evaporation structure is less, can't mate with big refrigeration unit, therefore refrigeration is not fine, in addition, this extinguishing device can't be adjusted by artificial when air pressure does not reach predetermined value.
Summary of the invention
Goal of the invention of the present invention is to overcome the shortcoming of above-mentioned CO, and a kind of good refrigeration effect is provided, the adjustable constant-pressure storage type high-pressure carbon dioxide extinguishing device that has built-in evaporator of gas temperature in the hold-up vessel.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of constant-pressure storage type high-pressure carbon dioxide extinguishing device that has built-in evaporator, comprise evaporimeter, evaporimeter is positioned at hold-up vessel, the inlet pipe of evaporimeter with go out pipe and pass hold-up vessel respectively and link to each other with refrigeration unit; Heating component is installed in hold-up vessel.
Described hold-up vessel is the vertical or horizontal pressure vessel that metal or nonmetallic materials are made.
Described evaporimeter is that the tubing or the tube sheet combination of resistant material made, and the evaporimeter that tubing or tube sheet constitute adopts spiral surrounding to form overlapping shape structure or comes inflection around forming overlapping shape structure.
The temperature that described hold-up vessel is stored extinguishing chemical is 15 ℃～17 ℃, and corresponding pressure is 5.1MPa～5.3MPa.
The temperature that traditional high-pressure carbon dioxide fire extinguishing system is stored extinguishing chemical is 0 ℃～+ 49 ℃, corresponding maximum pressure is 15MPa, and the temperature of constant-pressure storage type high-pressure carbon dioxide extinguishing device storage extinguishing chemical of the present invention is 15 ℃～17 ℃, corresponding pressure is 5.1MPa～5.3MPa, greatly reduce the bearing capacity of hold-up vessel, reduce the cost of system, improved the reliability of system.The present invention is positioned at evaporimeter in hold-up vessel, be used for reducing the temperature of the carbon dioxide extinguishing agent of constant-pressure storage type high-pressure carbon dioxide extinguishing device, the temperature of carbon dioxide extinguishing agent is crossed when hanging down in installing, with the heating component heating that is positioned at hold-up vessel, improve the temperature of carbon dioxide extinguishing agent in the hold-up vessel, the temperature maintenance of carbon dioxide in the hold-up vessel is moved in range of set temperature, the pressure that keeps carbon dioxide in the hold-up vessel, in addition, because evaporimeter is positioned at the cavity of hold-up vessel inside, placement space is big, therefore evaporimeter can be done bigger, the coupling refrigeration unit is convenient like this, and helps improving refrigerating efficiency, cuts down the consumption of energy.
The beneficial effect of constant-pressure storage type high-pressure carbon dioxide extinguishing device of the present invention is: efficiently solve that high-pressure carbon dioxide fire extinguishing system extinguishing chemical floor space is big, cost is also high and low pressure CO 2 extinguishing device short problem of fed distance when spurting, be easy to generate the stifled difficult problem of ice, simultaneously, pressure carbon dioxide can be kept by the temperature of adjusting carbon dioxide in the hold-up vessel in the good refrigeration effect of the present invention, hold-up vessel.
