Description

Technical Field

[0001] The utility model relates to an air suction mixed cooling device for an air compressor, belonging to the technical field of air compressors. Background Art

[0002] At present, large air compressor components mostly use cooling water to absorb compression heat, and then the cooling water pump pressurizes it to the cooling tower to dissipate the heat to the outdoor air. However, the cooling tower is affected by the weather and temperature, and the cooling water temperature will be affected. In the hot summer season, due to the high outdoor temperature, the cooling water temperature is high. At this time, the only way to maintain the air compressor outlet temperature is to increase the cooling water flow, which increases the energy consumption of the cooling water pump. When the production load increases, the air compressor outlet temperature will also increase. At this time, the compressor efficiency will decrease (the exhaust flow rate of the air compressor will decrease by about 1-2% for every 1°C increase in the air compressor). This process increases the energy consumption of compressed air components in summer, and the cooling effect is not satisfactory.

[0003] Therefore, in response to the existing process bottleneck, the air compressor cooling component was reshaped. While solving the problem of excessively high operating temperature of the air compressor, a new compressed air cooling device was developed. The internal cold energy of the component was used to pre-cool the inhaled air, seeking a new way to cool the air compressor. Summary of the invention

[0004] The utility model provides an air compressor suction hybrid cooling device, which solves the problem mentioned in the background technology that the cooling tower is affected by the weather temperature, and the cooling water temperature will be affected. In the high temperature season in summer, due to the high outdoor temperature, the cooling water temperature is high. This is the only way to increase the cooling water flow rate to maintain the air compressor outlet temperature, which increases the energy consumption of the cooling water pump. When the production load increases, the air compressor outlet temperature will also increase. At this time, the compressor efficiency will decrease (the exhaust flow rate of the air compressor will decrease by about 1-2% for every 1°C increase in the air compressor exhaust flow rate).

[0022] As a preferred example, a baffle is provided at the front end of the water collecting plate to prevent water from flowing back into the air compressor.

[0023] As a preferred example, a temperature and humidity sensor is installed on the inner wall of the emergency dewatering mechanism body, the temperature and humidity sensor is electrically connected to a controller, and the controller is electrically connected to the solenoid valve.

[0025] A first connecting pipe connected to the refrigerated dryer;

[0026] a second connecting pipe connected to the first connecting pipe;

[0027] a valve, connected to the second connecting pipe, for opening or closing the second connecting pipe;

[0029] The cold compressed air pipe is connected to the second connecting pipe, and the cold compressed air pipe is provided with a plurality of bronchial tubes, and the bronchial tubes are connected to the solenoid valve.

[0030] As a preferred example, the cooling method using the above device includes an air disturbance mixing and water removal stage S1 and an air cooling stage S2;

[0031] The air disturbance stage S1 comprises the following steps:

[0032] S1-1, After the air compressor is started, the air first passes through the inlet diffuser for pre-dispersion;

[0033] S1-2, after the air passes through the pre-dispersion, it passes through the disturbance blades to further disturb the diffused air. At this time, the disturbance blades use the power of the air sucked in by the air compressor to rotate and provide a disturbance effect;

[0034] S1-3, after the above steps, the air enters the mixer and mixes with the cold air;

[0035] S1-4, the mixed low-temperature air passes through the temperature and humidity sensor in the emergency dehydration mechanism to measure the temperature and humidity of the mixed air. At this time, the temperature and humidity of the temperature and humidity sensor are converted into electrical signals and sent to the controller. The controller gives instructions according to the preset temperature and humidity sensor signals to control the corresponding solenoid valve to open or close to control the amount of cold air, and control the mixed air to maintain a certain temperature (keep the air entering the compressor above the dew point temperature), and then enter the air compressor for compression after passing through the emergency dehydration mechanism;

[0036] The air cooling stage S2 comprises the following steps:

[0037] S2-1, open the inlet valve of the second connecting pipe through which the cold compressed air at the outlet of the refrigerated dryer passes, and the cold compressed air enters the bronchus of the cold compressed air pipe outside the mixer and in front of the solenoid valve along the second connecting pipe;

[0038] S2-2, the solenoid valve, according to the signal command given by the controller, causes the multi-layer opposing cold compressed air atomizing nozzles to spray cold compressed air in a staggered intermittent manner;

[0040] S2-4. The temperature and humidity signals of the mixed air are fed back to the controller by the temperature and humidity sensor. The controller sends an opening or closing instruction to the corresponding solenoid valve according to the preset signal to adjust the opening time and repetition of the cold compressed air atomizing nozzle to control the temperature and humidity of the mixed air, so as to ensure that the temperature of the inhaled air is above the dew point temperature. When the temperature is high, the opening time and repetition of the cold compressed air atomizing nozzle are increased, and the cold compressed air flow rate is increased to increase the cooling effect; when the temperature is low, the opening time and repetition of the cold compressed air atomizing nozzle are reduced, and the cold compressed air flow rate is reduced to reduce the cooling effect; this process uses air humidity as a mandatory warning signal. Regardless of the temperature after mixing, as long as the humidity is too high, the amount of cold air injection is forced to be controlled. When the humidity is too high, the amount of cold air injection is reduced. When the humidity is too low, the amount of cold air injection can be increased.

[0041] S2-5. After the above steps, the cold compressed air is formed into a spiral intermittent atomization, and is mixed with the air with a higher indoor temperature in the mixing chamber of the mixer and cooled before entering the next process.

[0042] The beneficial effects of the utility model are:

[0043] 1. The utility model solves the current industry situation in which the exhaust temperature of air compressors is too high in summer, the efficiency is reduced, the cooling method is single, and the resource utilization rate is low. At the same time, the use of cold compressed air dried by the refrigerated dryer in the system to provide cooling energy is also an important part of improving resource utilization. It seeks a new way for air compressor cooling and reduces cooling pressure.

[0044] 2. The inlet air disturbance mechanism adopts disturbance blades, which use the kinetic energy of suction to rotate the disturbance blades, and at the same time disturb the air flow state to improve the mixing effect and uniformity of the air entering the mixer.

[0045] 3. The mixer is essentially designed as a hybrid heat exchanger, with multiple nozzles arranged in a staggered manner. Each nozzle is equipped with a solenoid valve to control the amount of cold compressed air entering, so that the cold compressed air is dispersed in the mixer and fully mixed with the hot air to increase the heat exchange effect.

[0046] 4. An emergency water removal mechanism is set between the mixer outlet and the air compressor inlet, so that the cooled air forms an "S"-shaped flow route in the emergency water removal device, increasing the residence time in the device, improving the ability to remove small water droplets in the air, and protecting the air compressor equipment.

[0047] 5. The cold energy used by the mixer is provided by the cold compressed air delivery system. This process uses a part of the unused cold energy (compressed air with lower temperature) at the outlet of the refrigerated dryer in the compressed air system. If this part of the cold energy is not used in the system, it will slowly disappear. Therefore, this process extracts this part of the cold energy to pre-cool the air inlet of the air compressor and improve the efficiency of the air compressor. BRIEF DESCRIPTION OF THE DRAWINGS

The repetition of each group of cold compressed air atomizing nozzles 16 can be increased or decreased according to the temperature. When the relative humidity of the air reaches the dew point temperature at this temperature, the controller 2 issues a command to force the solenoid valve 17 to close the injection of cold air according to the signal from the temperature and humidity sensor 15 to prevent air condensation.
