Abstract
The utility model discloses a built -in evaporimeter for low pressure carbon dioxide extinguisher, low pressure carbon dioxide extinguisher includes the storage tank and sets up at the outside refrigerating system of storage tank, the evaporimeter setting is connected to form in the storage tank and with refrigerating system and is closed circulation circuit, the coil pipe structure of evaporimeter for being continuous S -shaped and arranging, the evaporimeter is whole to be fixed in the storage tank on the coplanar and through the coil pipe mount, the heat transfer area that the evaporimeter formed is not less than the storage tank and follows the half the of the vertical cross sectional area of its axial. The utility model discloses a structural design of evaporimeter, greatly increased the heat transfer area of evaporimeter for the storage tank inner space to effectively solved the frequent problem that starts of refrigerating system that low pressure carbon dioxide exists when ambient temperature condition on the high side is stored, refrigeration effect is good moreover, and carbon dioxide pressure can be maintain through carbon dioxide's in the adjustment storage tank temperature in the storage tank.
Description
Technical field
The utility model belongs to fire-fighting equipment technical field, particularly a kind of built-in evaporimeter for low pressure CO 2 extinguishing device.
Background technology
At present, low pressure CO 2 extinguishing device uses more and more extensive, such as power plant, Pulverized Coal Bin, cement plant etc. We know that the pressure of carbon dioxide extinguishing agent in low pressure CO 2 extinguishing device varies with temperature and changes, so be a key for the storage of low pressure CO 2.
In above-mentioned application places, all difference to some extent of its environment temperature, the refrigeration system of conventional low pressure CO 2 extinguishing device general 24h in the situation that environment temperature is higher starts once, and existing built-in evaporimeter mostly is helical structure and be connected on ring flange by support, its heat exchange area is relatively little, cause refrigeration system frequent starting, and need the long period just can reach relevant temperature requirement, thereby shortened the service life of refrigeration system, and fixing stable not in storage tank of evaporimeter.
Utility model content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of built-in evaporimeter for low pressure CO 2 extinguishing device of good refrigeration effect.
The technical scheme of the utility model technology is achieved in that a kind of interior device for low pressure CO 2 fire extinguishing puts formula evaporimeter, described low pressure CO 2 extinguishing device comprises storage tank and is arranged on the refrigeration system of storage tank outside, described evaporimeter is arranged in storage tank and is connected to form and closes closed circuit with refrigeration system, it is characterized in that: described evaporimeter is to be the coil arrangement that continuous S-shaped is arranged, described evaporimeter entirety is fixed in storage tank at grade and by coil pipe fixed mount, the heat exchange area that described evaporimeter forms is not less than the half of storage tank along its axial vertical section area.
Built-in evaporimeter for low pressure CO 2 extinguishing device described in the utility model, described in it, coil pipe fixed mount has two at least, and its two ends are fixedly connected on respectively on the inwall of storage tank, and described evaporimeter is evenly arranged and is fastened on coil pipe fixed mount.
Built-in evaporimeter for low pressure CO 2 extinguishing device described in the utility model, in the liquid Space that described in it, evaporimeter bottom is placed in storage tank, in the gas-phase space that its top is placed in storage tank.
The utility model is by the structural design of evaporimeter, greatly increase the heat exchange area of evaporimeter with respect to tank inside space, thereby efficiently solve the problem of low pressure CO 2 refrigeration system frequent starting of existence in the time that the higher condition of environment temperature stores, and good refrigeration effect, in storage tank, pressure carbon dioxide can maintain by the temperature of adjusting carbon dioxide in storage tank.
Brief description of the drawings

Mark in figure: 1 is storage tank, 2 is refrigeration system, and 3 is evaporimeter, and 4 is coil pipe fixed mount.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model technology is further elaborated. Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of built-in evaporimeter for low pressure CO 2 extinguishing device, described low pressure CO 2 extinguishing device comprises storage tank 1 and is arranged on the refrigeration system 2 of storage tank 1 outside, described evaporimeter 3 is arranged in storage tank 1 and is connected to form and closes closed circuit with refrigeration system 2, the coil arrangement that described evaporimeter 3 is arranged for being continuous S-shaped, described evaporimeter 3 entirety are fixed in storage tank 1 at grade and by coil pipe fixed mount 4, and the heat exchange area that described evaporimeter 3 forms is not less than the half of storage tank 1 along its axial vertical section area.
Wherein, described coil pipe fixed mount 4 has two at least, its two ends are fixedly connected on respectively on the inwall of storage tank 1, described evaporimeter 3 is evenly arranged and is fastened on coil pipe fixed mount 4, in the liquid Space that described evaporimeter 3 bottoms are placed in storage tank 1, in the gas-phase space that its top is placed in storage tank 1.
Operation principle of the present utility model is: refrigeration system is made up of compressor, condenser, capillary, evaporimeter etc., they is connected into a sealing system with pipeline. refrigerant liquid in evaporimeter with low temperature and low pressure CO 2 generation heat exchange, absorb heat the gasification of low pressure CO 2, the low-pressure steam producing is sucked by compressor, discharge with high pressure after compression, the high-pressure gaseous refrigerant that compressor is discharged enters condenser, air by normal temperature is cooling, condense into highly pressurised liquid, throttling when highly pressurised liquid is flowed through expansion valve, become the gas-fluid two-phase mixture of low-pressure low-temperature, enter again evaporimeter, the sweat cooling in evaporimeter of liquid refrigerant wherein, the low-pressure steam producing is sucked by compressor again, so go round and begin again, constantly circulation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
