Description

Intelligent wearing equipment for coal occupational disease protection and coal occupational disease prevention and control method

Technical Field

The invention relates to intelligent protective wearing equipment for coal occupational diseases and a method for preventing and treating the coal occupational diseases, in particular to protective equipment and a method for protecting human health and preventing and treating the occupational diseases in coal.

Background

The environment in the mine is very harsh, and a large amount of dust, harmful gas, noise of working machinery and a high-temperature humid environment form four harms of underground work. The four pests seriously harm the health of underground workers and must be prevented and controlled. The traditional control method for four pests comprises the following steps:

(1) a filtering face mask or a mouth mask. The defect is that the mask or the mouth mask needs to be tightly fixed with the head, and the wearing comfort is poor; the application scene of the coal mine is extremely severe, particularly the dust concentration in the air of a working face is very large, the dustproof effect is not ideal, and the incidence rate of pneumoconiosis cannot be effectively reduced; harmful gases such as carbon monoxide, methane, hydrogen sulfide, sulfur dioxide, oxynitride and the like cannot be effectively filtered, the protection effect on the harmful gases is weak, and the harm of the harmful gases to human bodies cannot be effectively prevented.

(2) An isolated mask or a mouth mask matched with a breathing air supply system. The isolation type mask or mouth mask has the disadvantages of poor isolation effect and incapability of completely isolating dust and harmful gas in the external environment. The breathing gas supply system matched with the isolated mask or gauze mask mainly has three types: the portable compressed oxygen cylinder or the chemical oxygen reaction generator provides oxygen with higher concentration for the breathing requirement of a human body, and has the defect that the breathing with higher concentration for a long time causes oxygen poisoning or other diseases to the human body, so the breathing oxygen supply system is often used as temporary emergency rescue equipment and cannot be popularized and used in long-term continuous operation; the portable compressed air bottle is limited in volume, the oxygen volume fraction in the air is only about 21%, and the oxygen volume carried in each time is limited, so that the continuous operation time is short, and the application is limited; the fixed compressed air bottle can store large-capacity purified air, and has the defect that the fixed compressed air bottle and an operator need to be connected through a breathing long pipe, so that the operator can only operate in a short distance nearby the fixed compressed air bottle, and the maneuvering flexibility is limited.

(3) Completely isolated oral appliance and nasal clip, and matched with breathing air supply system. Completely isolated oral appliances and nasal clamps close a channel for nasal breathing by using the nasal clamps, and dust and harmful gas in the external environment can be completely isolated only by breathing with the mouth of the oral appliances, but the breathing habit of human is violated, so special training is required before use, and the nasal clamp is often used as temporary emergency rescue equipment. The breathing air supply systems matched with the completely isolated oral appliance and the nose clip are mainly three, are completely the same as the breathing air supply systems matched with the isolated mask or the mouth mask, and are not repeatedly described.

(4) The earplug is equipped for noise protection, so that noise can be isolated, but a way for information communication with other personnel is also isolated, and the use is very inconvenient.

The prior technical scheme mainly aims at the protection of the breathing process and mainly protects dust, most equipment has no function on harmful gas, and the influence of high temperature and humidity on human bodies cannot be protected at all, or the prior technical scheme which can protect four hazards of occupational diseases in the coal industry is unavailable.

Detailed Description

The first embodiment is as follows:

the embodiment is intelligent wearing equipment for coal occupational disease protection, and is shown in figures 1, 2 and 3. The embodiment comprises the following steps: the protective suit 2 with the helmet 1 and the inner space is communicated with a pure oxygen source 4 in the helmet through an oxygen valve 3; the air source 6 is communicated with the inner space of the protective clothing through an air valve 5, the electric control ends of the air valve and the oxygen valve are electrically connected with a controller 7, and the controller is electrically connected with an oxygen concentration sensor 8 arranged in the helmet. The protective clothing is also provided with an air circulating device 9 which comprises an air inlet 901 communicated with the inner space of the protective clothing, and the air inlet is sequentially communicated with a filter 902, an air circulating pump 903 (the part of a dotted line frame in fig. 2) and an air outlet 904 communicated with the inner space of the protective clothing through pipelines (the pipelines are represented by thick solid lines in fig. 2); the lower part of the protective suit is also provided with a pressure relief valve 10 which communicates the internal space of the protective suit with the atmosphere, as shown in fig. 2.

The intelligent protective wearing equipment for the coal occupational disease aims to establish an internal space isolated from the outside in the protective clothing. This inner space has the clean air that supplies the breathing, is fit for human temperature and humidity to isolated outside noise provides the comfortable environment that can work for a long time for the staff in the pit, and can avoid or reduce the equipment of injury in the emergence incident. Because of the clean air, the personnel can be completely prevented from being invaded by silicosis and toxic air, the control of temperature and humidity prevents the personnel from being disturbed by damp heat, and the noise is isolated to prevent the personnel from being suffered from diseases such as deafness and the like.

The difficulty and key to this embodiment is to provide a clean air supply for a long period of time. The mine is a closed and narrow working environment, dust tends to concentrate on the working surface and is difficult to disperse, and if a filter is used, the dust quickly becomes blocked and cannot be used in the environment. If a conventional compressed air cylinder is used, it can only be maintained for a short time. If a pure oxygen compressed gas cylinder is used, problems such as oxygen poisoning may be encountered.

The embodiment provides a technical scheme capable of supplying pure air for a long time: the oxygen is supplied from a pure oxygen source in mutual use, and the air is supplied from an air source in part for cleaning, so that the pure oxygen and the air are mixed. Oxygen in the pure air comes from compressed oxygen bottle or chemical oxygen generator, nitrogen comes from a small-size compressed air bottle or compressed nitrogen bottle (nitrogen does not consume at human breathing in-process, therefore the available small-size gas cylinder of nitrogen, the effect is the proportion of oxygen and nitrogen in the regulation air feed, satisfy human breathing needs), oxygen concentration sensor real-time supervision breathes the oxygen concentration in the air supply system, and transmit oxygen concentration signal to the treater, the treater is according to the air feed proportion of oxygen concentration information timely regulation control oxygen and nitrogen, make it accord with human breathing needs. When a person breathes, carbon dioxide is generated, oxygen and air or nitrogen are continuously supplemented in the helmet, the carbon dioxide exhaled by the person is extruded out of the helmet, so that the carbon dioxide in the helmet can be maintained at a safe level, and the carbon dioxide extruded out of the helmet by the oxygen and the air is filtered out in the internal space of the protective suit through a filter of the air circulating device, so that the air in the internal space of the protective suit is kept fresh. To further prevent excessive carbon dioxide, a carbon dioxide concentration sensor 101 (see fig. 3) may be provided in the helmet to increase the supply of oxygen or air to maintain the freshness of the air in the helmet when the carbon dioxide in the helmet exceeds a certain limit.

In addition, the pure oxygen gas source and the air gas source also need to be provided with safety parts such as a pressure gauge, an alarm, a safety valve and the like, so that the whole system can run safely and reliably. When the oxygen source is insufficient, the alarm gives an alarm to remind people to replace the compressed oxygen cylinder or the chemical oxygen generator in time. The safety valve sets the upper pressure limit for the compressed oxygen cylinder or the chemical oxygen generator to play a role in protection.

The oxygen and air sources may also be connected to the administration set 401. The administration device has the functions of adding some medicines for cleaning the lung, adding atomized medicines and treating respiratory system and skin diseases. The administration set may be connected to a pure oxygen source, as shown in fig. 3, with the addition of a bypass selector valve 402, which is electrically connected to the controller.

The body of this embodiment is a protective garment with a helmet. The body part of the protective clothing is made of soft materials, has the capability of heat insulation and the equivalent toughness and has certain capability of resisting the puncture of sharp substances. The material of the protective garment must be light so that a person can move freely after wearing the protective garment. It is important that protective garments differ from conventional garments in that there is a space for air to flow within. The air can flow in the protective clothing, so that the ability of taking away the heat emitted by the human body can be achieved. Because the protective clothing is thermal-insulated, outside heat can not get into the protective clothing, and the heat of inside also can not directly release outside, but the human body can give off the heat, if do not have the passageway with human heat release, the people can't normally live, do nothing to work. Therefore, the key to this embodiment is to provide an interior space of the protective garment that allows air flow.

The inner space of the protective clothing has a more important function of assisting breathing in addition to the function of discharging heat released by the human body. The scheme for solving the problem of human breathing is that air in a limited space is combined with pure oxygen and carbon dioxide exhaled by a human body to form air suitable for human breathing. This limited space must be large enough to achieve good mixing of the air. If it is not sufficient to rely solely on the space within the helmet, this embodiment combines the helmet and the body part of the suit to form a space sufficient to contain a quantity of air, and provides an exhaust port remote from the pure oxygen outlet to remove a portion of the air having a lower oxygen concentration, so that the interior space of the suit contains fresh air.

In order to keep the inner space of the protective clothing fresh, the air circulation device is also arranged in the embodiment. In order to keep the air in the inner space of the protective clothing fresh, the air circulating device is provided with facilities for filtering, cooling, dehumidifying and the like so as to maintain the small environment in the protective clothing suitable for the activity of the human body.

The filter can absorb harmful parts in the air such as carbon dioxide exhausted by breath and peculiar smell in the system, and the like, thereby keeping the inner space of the protective clothing clean and fresh. The filter can also be used as the redundant arrangement of the system, and can absorb dust entering the inner space of the protective clothing if special conditions such as sealing failure of the inner space of the protective clothing occur, maintain the breathing and air supply functions of the system and wait for repair. Under normal conditions, the filter only absorbs substances with small particles, so that the service life is long, the filter can be used repeatedly, the filtering efficiency is reduced after a certain time, and the filtering capacity of the filter can be recovered by a heating and baking method, so that the use cost of the protective equipment is reduced.

In the embodiment, temperature and humidity sensors 11 and 12 are provided, and as shown in fig. 2, the controller intelligently controls the temperature and humidity of the inner space of the protective clothing according to the temperature and humidity information transmitted by the sensors: when humidity exceeded certain numerical value in the inner space of protective clothing, the dehumidification function will be opened automatically to the controller according to humidity transducer's feedback signal, absorbs unnecessary vapor, makes the interior air humidity of system keep in certain scope, neither too moist, and is too dry again, makes the personnel of dress obtain more comfortable impression.

The dehumidification function can be realized by arranging the components such as the water-vapor separator 905, the water-vapor bypass pipeline 906 and the water-vapor separation valve 907, and the like, as shown in fig. 2. The electric control end of the water-vapor separation valve is electrically connected with the controller. When the humidity is too high, the controller controls the water-vapor separation valve to selectively pass through the water-vapor separator, so that the circulating air passes through the water-vapor separator to filter the moisture in the air; when the air humidity is proper, the water-vapor bypass pipeline is selected by the water-vapor separation valve, namely, the circulating air directly enters the inner space of the protective clothing without passing through the water-vapor separator, so as to ensure the proper air humidity.

The temperature control function may be achieved by providing a heat sink 910 with louvers 908 and fans 909 on the air circulation line, as shown in FIG. 2. The heat sink may be a tube bundle heat exchanger. The air passes through the tube bundle and conducts heat to the fins on the tube bundle, which transfer the heat to the atmosphere. The heat dissipation on the heat sink can be accelerated by the fan, so that the heat exchanger can be provided with the fan and the louver, the louver is provided with a opener 911 (see fig. 2) for controlling the opening of the louver, the fan and the opener are electrically connected with the controller, the opener controls the louver to be opened when the temperature of the inner space of the protective clothing rises, and the fan is opened again if necessary to accelerate the heat dissipation. A cooling device, such as a semiconductor cooling plate 912 (see fig. 2) or a micro cooling pump, may be further disposed on the heat exchanger to make the heat exchanger a refrigerator, so that the interior space of the protective clothing is maintained at a temperature suitable for the human body.

The mine needs to be provided with a safety helmet, so that the helmet in the embodiment also has the functions of the safety helmet, communication, illumination and the like, which is different from the common sealed protective clothing. For the impact of preventing the heavy object, this embodiment the top of helmet is impact-resistant material inside lining buffer material, and the face is thermal-insulated, the transparent impact-resistant material that gives sound insulation, and other parts are impact-resistant material, and the inside lining is thermal-insulated, sound-proof material, and the neck fuses the UNICOM completely with the inner space of protective clothing. Meanwhile, a wireless voice call device 102 and a lighting headlamp 103 are arranged in the helmet, as shown in fig. 1.

The protective suit is also associated with gloves 201 capable of operating a touch screen and rubber boots 202 having anti-pounding, waterproof and insulating capabilities. The gloves and rubber boots described in this embodiment are isolated from the interior space of the protective garment, i.e., the hands and feet are exposed after the garment is worn, and the interior space of the protective garment is sealed to the lower arms and legs for ease of handling other equipment, unlike protective garments for most other uses.

The gloves and rubber boots described in this embodiment may be conventional gloves and rubber boots, or may be heat dissipation pipes with internal connections to the air circulation device pipes to remove excess heat generated by the hands and feet during activities.

In order to make the whole equipment more light and easy to maintain, some harnesses, which often need to be maintained and replaced frequently, can be integrated into one backpack 13 (see the part of the dashed box in fig. 2), such as compressed air or compressed nitrogen and oxygen cylinders or chemical oxygen generators, a controller and a battery 14, and a circulation pump of an air circulation device, a cooling device, a dehumidifying device, etc.

The whole equipment is made of flame-retardant and anti-static materials, so that the equipment has the working capacity in a special environment, and the equipment can be applied to the coal industry, can also be used in non-coal industry, metal mines, cement, construction sites and other operation occasions with serious dust, and has a remarkable effect of preventing occupational pneumoconiosis.

The embodiment has the characteristics of light-weight portable breathing gas supply system, has the ability of complete isolated protection, can prevent four pests, and is multiple in function, complete intelligent in operation, convenient in disassembly, cleaning, maintenance and repair, good in economical efficiency, and capable of considering continuous operation and emergency situations.

Example two:

the example is a method of coal occupational disease protection using the equipment of example one. According to the method, the intelligent protective wearing equipment which is completely isolated from the outside is adopted, so that the method is more effective and more stable than the most common filtering type protective equipment, the protective efficiency can reach 100% theoretically, the severe working environment of a coal mining working surface can be met, and the health of operators is guaranteed. The intelligent wearing equipment for the coal occupational disease protection has all functions, and can play a comprehensive protection role on four hazards of occupational diseases in the coal industry, including dust, harmful gas, noise, heat hazards and the like. The equipment is completely intelligent, manual operation is not needed, the change of the temperature, the humidity and the oxygen concentration in the system is intelligently sensed through the sensor, and the change is timely fed back to the processor, the rotating speed of the motor and the ventilator is adjusted, whether the steam-water separator is connected, whether the radiator fan is opened, the opening degree of the shutter of the radiator, the proportion of oxygen and nitrogen in the respiratory gas supply and the like are adjusted and controlled, so that the temperature, the humidity and the oxygen concentration in the system are kept in a relatively comfortable range. In equipment and system design, the life-cycle use cost of the equipment is reduced by considering factors such as economy, for example, the recyclable use of the multifunctional filter and the like.

The method of the embodiment includes the following specific steps, and the flow is shown in fig. 3:

step S1, wearing the equipment: the protective clothing is worn, the wrist and the ankle are airtight, the rubber shoe belt is worn to wear the gloves, the heat dissipation pipeline of the rubber shoe and the gloves is connected, the backpack is worn on the back, the pipeline and the circuit are connected, and the helmet pipeline and the circuit are connected.

The process of wearing the equipment is to wear the body part of the protective clothing firstly, then carry on the backpack, and communicate the pipeline and the circuit. The key to the donning is the sealing of the arms and legs, completely isolating the interior space of the suit from the exterior. The protective clothing should be worn mainly by self-wearing and be worn by others to avoid the design of wearing by others.

Step S2, start the controller: starting the controller to perform self-checking of the controller, and detecting the states of each valve and each sensor, the state of the wireless voice communication device and the state of the head lamp; and starting the air circulation device and detecting the working state of the air circulation device.

After the helmet is worn, the protective suit is completely isolated from the outside, so that the initial detection of the system is very important for communicating the inside and the outside, and therefore, the inside and the outside communication modes of the protective suit are redundant, namely, a plurality of sets of communication modes including wireless communication, wired communication, gestures and the like are required, so that the protective suit can be fully communicated with the outside by a wearer after the helmet is worn, and the wearer can immediately express the communication to the outside once physical discomfort occurs. The ratio of oxygen to air should be initially adjusted to allow the person to breathe normally, so that the person can breathe normally when wearing the helmet. However, since the oxygen concentration sensor is exposed to the atmosphere, the dissolved oxygen inside the protective clothing cannot be monitored accurately, and only can be used as a reference.

Step S3, wearing a helmet: the helmet is worn and is connected with the protective clothing in an airtight manner, and the working state of the whole equipment is detected: and opening an oxygen valve and an air valve, adjusting the proportion of oxygen and air in the helmet by the controller through an oxygen concentration sensor, and adjusting the temperature and humidity of the inner space of the protective clothing through a temperature sensor and a humidity sensor.

After the helmet is worn, the whole equipment is in a fully automatic monitoring state, and at the moment, the temperature, the humidity, the dissolved oxygen and the like are under the monitoring of each sensor. In order to avoid danger, the helmet and the body part of the protective suit can be quickly separated, and a safety valve capable of being quickly opened is arranged on the helmet, so that a wearer or other personnel can quickly communicate the helmet with the outside.

The following steps S4, 5 and 6 are carried out simultaneously, and the following three steps are the normal working state of the protective clothing:

step S4, the breathing control process: the controller passes through the oxygen concentration in the oxygen concentration sensor real time monitoring helmet, because the oxygen hose export has a section distance apart from the mouth nose, consequently, the inhaled not pure oxygen of human body, but the air that has certain nitrogen gas and carbon dioxide, when the pure oxygen concentration is too big, input a certain amount of air, because the export of pure oxygen source and air supply all sets up in the helmet, make the pressure in the helmet increase, and output pressure to in the other parts of protective clothing, when the pressure of the inner space of protective clothing is enough big, the relief valve is opened, discharge the unnecessary gas of protective clothing inside air.

Since the breathing process of a person is mainly oxygen consumption and other parts of the air are not substantially digested, this embodiment mainly supplies oxygen during the breathing control process, while the inner space of the protective suit provides the opportunity for air and oxygen to mix, providing air with a higher oxygen concentration and suitable for breathing in the helmet, and exhausting air with a lower oxygen concentration out of the protective suit through the pressure relief valve. The air source is opened only when the pressure in the inner space of the protective clothing is insufficient, and the shortage of the supplementary air is overcome, so that the air source is used for a very small amount. By utilizing the principle, the oxygen consumption and the air consumption are saved, the two air sources can be relatively reduced, and the light weight is successfully realized.

Step S5, temperature control process: the controller monitors the temperature of the inner space of the protective clothing in real time through the temperature sensor, and opens or closes the shutter, the fan and the semiconductor refrigeration sheet as strategies for coping with temperature increase or decrease.

The main function of the interior space of the protective garment is to provide a space for air circulation, which is a heat-dissipating medium through which heat is removed from the body and conducted to the atmosphere during temperature control. The human body can produce the heat in the activity, if untimely heat dissipation, the human body can produce the discomfort, and air circulation device's temperature sensor regards the temperature of the inner space of protective clothing as the detection object, is equivalent to the temperature that detects the human body. Through the automatic data that detects according to temperature sensor of controller, in proper order open the shutter, further open the fan, further open refrigeration piece etc. again and improve the cooling effect, perhaps reduce refrigeration effect on the contrary, keep the inside temperature of protective clothing.

Step S6, humidity control process: the controller monitors the humidity inside the protective clothing in real time through the humidity sensor, and selects the linkage water vapor separator or the bypass water vapor separator as a strategy for coping with the humidity increase or decrease.

The humidity control process of the inner space of the protective clothing mainly controls whether the circulating air passes through the water-vapor separator or not, when the humidity of the inner space of the protective clothing is large, the circulating air passes through the water-vapor separator, the moisture in the air is separated and removed, when the humidity is small, the circulating air is circulated through the bypass pipeline, and the water-vapor separation is not carried out.

Step S7, end: firstly, opening the air tightness of the helmet, taking off the helmet, then closing the pure oxygen source, then closing the air source, closing the controller, taking off the gloves and the rubber boots, then taking off the protective clothing, and separating the protective clothing from the backpack.

The finishing process is to open the helmet firstly to enable the person to breathe natural air so as to ensure the safety of the person.

Finally, it should be noted that the above only illustrates the technical solution of the present invention, but not limited thereto, and although the present invention has been described in detail with reference to the preferred arrangement, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made thereto without departing from the spirit and scope of the technical solution of the present invention.
