Abstract
The utility model discloses a carbon dioxide refrigerating device used in a refuge chamber. The carbon dioxide refrigerating device comprises a liquid carbon dioxide high-pressure gas cylinder arranged in a refuge chamber device cabin, a temperature sensor and an evaporator, wherein the temperature sensor and the evaporator are arranged in a refuge chamber personnel cabin. The liquid carbon dioxide high-pressure gas cylinder is connected with an evaporator through a pipeline which is provided with a throttling valve. An outlet of the evaporator is led out of the refuge chamber personnel cabin through the pipeline, and a pipeline opening is connected with a nozzle. When the carbon dioxide refrigerating device used in the refuge chamber works, the liquid carbon dioxide high-pressure gas cylinder provides low-temperature liquid carbon dioxide for the evaporator through the throttling valve, and the liquid carbon dioxide is changed into gas by absorbing heat and expanding at the evaporator, and the gas is ejected by the nozzle. The purpose of refrigerating is achieved at the evaporator. The carbon dioxide refrigerating device is simple in structure, convenient to use and easy to manufacture.
Description
Technical field
The utility model relates to a kind of carbon dioxide refrigeration device, especially a kind of for the carbon dioxide refrigeration device in refuge chamber.
Background technology
Refrigeration Technique is a core technology in process of coal mining, and common most of collieries all can be used corresponding Refrigeration Technique, and especially, in refuge chamber the inside, refrigeration is related to life security especially.When distress personnel enters after airtight refuge chamber, the temperature and humidity of refuge chamber can rise gradually, and conventional refrigeration modes has: ice-reserving refrigeration, electric refrigerator refrigeration etc.;
(1) first ice-reserving refrigeration will make ice by water, to maintain at ordinary times the icing state of ice therefore, need at ordinary times to power to electric refrigerator, maintenance cost is high, special in the time that gas overpressure is crossed power-off required concentration, the necessary power supply that cuts off refrigeration machine, therefore, ice-reserving refrigeration does not meet without large power supply without the non-maintaining economical and practical requirement that waits of potential safety hazard, and refuge chamber and survival capsule should not adopt ice-reserving refrigerating method.
(2) electric refrigerator refrigeration needs large-capacity battery or external large power supply in the time there is catastrophe under coal mine, external large power supply will have a power failure large-capacity battery and the refrigeration machine motor of non-intrinsically safe safety anti-explosive, in the time of gas exceeding limit, do not allow work, therefore, electric refrigerator refrigeration does not meet without large power supply without requirements such as potential safety hazards, and refuge chamber and survival capsule should not adopt electric refrigerator refrigerating method.
Be not difficult to find out, coal mine underground refuge chamber adopts these cooling methods all not utilize the stable of whole Waiting space.
Utility model content
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of simple in structure, easy to operate, effective for the carbon dioxide refrigeration device in refuge chamber.
Of the present utility model for the carbon dioxide refrigeration device in refuge chamber, comprise the liquid carbon dioxide gas cylinder that is located in refuge chamber equipment compartment, be located at temperature sensor, evaporimeter in refuge chamber personnel compartment, described liquid carbon dioxide gas cylinder is connected with evaporator pipeline, connected pipeline is provided with choke valve, the outlet of evaporimeter is drawn outside refuge chamber personnel compartment by the road, and mouth of pipe place is connected with nozzle.
Beneficial effect: carbon dioxide refrigeration device of the present utility model, adopts liquid carbon dioxide gas cylinder, temperature sensor, evaporimeter, nozzle, choke valve.The utility model is simple in structure, is easy to manufacture.Compared with prior art, have simple in structure, non-transformer, the advantage such as maintenance is little, and maintenance cost is low, and storage equipment volume is little, and cold storage capacity is large.With respect to electric refrigerator refrigeration, there is explosion-proof function, security performance is higher.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: liquid carbon dioxide gas cylinder-1, temperature sensor-2, evaporimeter-3, nozzle-4, choke valve-5, refuge chamber equipment compartment-6, refuge chamber personnel compartment-7.
The specific embodiment
Structure accompanying drawing is further described an embodiment of the present utility model below:
Carbon dioxide refrigeration device of the present utility model, mainly by being located at the liquid carbon dioxide gas cylinder 1 in refuge chamber equipment compartment 6, temperature sensor 2, the evaporimeter 3 being located in refuge chamber personnel compartment 7 forms, described liquid carbon dioxide gas cylinder 1 is connected with the evaporimeter 3 being located in refuge chamber personnel compartment 7 by the road, the pipeline being connected is provided with choke valve 5, the outlet of evaporimeter 3 is drawn outside refuge chamber personnel compartment 7 by the road, and mouth of pipe place is connected with nozzle 4.
Described temperature sensor 2 is for responding to the variations in temperature in refuge chamber, and when the temperature in refuge chamber is during higher than setting value, the personnel of refuge chamber just can open choke valve 5 voluntarily, and carbon dioxide refrigeration device is brought into operation, and reduce chamber temperature; When ambient temperature during lower than design temperature the personnel of refuge chamber close again choke valve 5.
When work starts, liquid carbon dioxide gas cylinder provides low temperature liquid carbon dioxide by choke valve 5 to evaporimeter 3, and liquid carbon dioxide is expanded and become gas by heat absorption at evaporimeter 3 places, is sprayed by nozzle 4, realizes refrigeration object at evaporimeter 3 places.
Claims (1)
