Background technology
The kind of air compressor is a lot, can be divided into positive displacement compressor, reciprocating compressor, centrifugal compressor by operation principle.Air compressor commonly used now has piston type air compressor, screw air compressor (screw air compressor is divided into double-screw air compressor and single-screw air compressor again), centrifugal compressor and sliding-vane air compressor, scroll type air compressor.
Wherein helical-lobe compressor is a rotary positive displacement compressor, and two rotors that have the screw type gear are meshing with each other therein, thereby with gas compression and discharge.In the long-continued running of screw air compressor, electric energy is converted to mechanical energy, tool can be converted to the interior energy of gas, in can process in mechanical energy is converted to, air obtains strong high pressure compressed, making it temperature rises sharply, this is a general physics mechanical energy conversion phenomena, the heat of high temperature that the high speed rotation of air compressor machine screw rod produces, while is frictional heating also, the heat of high temperature of these generations is mixed into oil/gas steam discharge body by the adding of air compressor machine lubricating oil, the heat of this part high temperature oil/air-flow is equivalent to 3/4 of air compressor machine input power, common 80 ℃-100 ℃ of its temperature, these heat energy are all because the requirement of machine running temperature, all discarded without rhyme or reason and be discharged in the atmosphere, the cooling system that is air compressor machine is finished the temperature requirement that machine moves, compressed air temperature after gs-oil separator separates also reaches 45~60 ℃, the heat of the two is dissipated in vain toward leaning on, very unfortunate, though also there are indivedual producers to produce the device that utilizes residual heat of air compressor hot water, but heat energy utilization is insufficient, and it is also not too convenient to use, and haves much room for improvement.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides the residual heat of air compressor of a kind of safety, energy-saving and environmental protection, applied range to recycle the hot water unit.
The technical scheme that its technical problem that solves the utility model adopts is: this a kind of residual heat of air compressor is recycled the hot water unit, comprises hot water unit cabinet and is arranged on cabinet outer air compressor machine, gs-oil separator and water tank; Be provided with control system, oil gas temperature sensor and the water pump that is linked in sequence by water pipe, heat exchanger in the cabinet; The water inlet of water pump is connected with the warm water outlet of water tank by water pipe, air compressor machine, oil gas temperature sensor, heat exchanger, gs-oil separator are linked in sequence by pipe-line, the delivery port of heat exchanger is by water pipe also be linked in sequence auxiliary heater, temperature sensor, and the delivery port of temperature sensor is connected with water tank warm water water inlet.
Hot water emission's mouth of water tank described in the utility model also is connected with another water pump by water pipe; Electrothermal tube or electromagnetic heating system are housed in the auxiliary heater, and heat exchanger is a plate type heat exchanger, and this electrothermal tube, plate type heat exchanger all are that those skilled in the art utilizes prior art to realize.
Compared with prior art, the utlity model has following advantage:
1. safety: will never there be the danger of electric leakage, electric shock, blast, gas poisoning in no any heating equipment in the storage tank.
2. energy-conservation: improve the gas production of air compressor machine 8%, the expense of a water pump and can obtain hot water has endlessly reduced financial cost.
3. environmental protection: noiselessness, do not discharge used heat again, waste water, any harmful substance such as waste gas.
4. applied range: be fit to all types of, the reducing energy consumption of various brands screw rod-type air compressor machine, the corporate boss kills two birds with one stone, and turns waste into wealth.
Description of drawings
Fig. 1 recycles hot water unit connection diagram for the utility model residual heat of air compressor.
The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is described in detail below in conjunction with accompanying drawing:
Fig. 1 is that the utility model residual heat of air compressor is recycled the hot water unit, comprises hot water unit cabinet 2 and is arranged on cabinet 2 air compressor machine 1, gs-oil separator 3 and water tank 4 outward; Be provided with control system 26, oil gas temperature sensor 23 and the water pump 21 that is linked in sequence by water pipe 6, heat exchanger 22 in the cabinet 2; The water inlet of water pump 21 is connected with the warm water delivery port of water tank 4 by water pipe 6, air compressor machine 1, oil gas temperature sensor 23, heat exchanger 22, gs-oil separator 3 are linked in sequence by pipe-line 5, the delivery port of heat exchanger 22 is by water pipe 6 also be linked in sequence auxiliary heater 24, temperature sensor 25, and the delivery port of temperature sensor 25 is connected with water tank 4 warm water water inlets.
In the above-mentioned auxiliary heater 24 electrothermal tube or electromagnetic heating system are housed; Heat exchanger 2 is plate type heat exchangers, and this electrothermal tube, plate type heat exchanger all are that those skilled in the art utilizes prior art to realize.
Referring to Fig. 1, hot water emission's mouth of water tank 4 also is connected with another water pump 21 by water pipe 6; Be provided with electrothermal tube in the auxiliary heater 24, when because continuous water or be subjected to ambient temperature to cross low the influence, when leaving water temperature is lower than a setting value for a long time, can start auxiliary heater 24, promptly the electrothermal tube heating power in the auxiliary heater 24 is assisted heating to the hot water that flows into after heat exchange, water temperature is risen, when the water temperature rising reached another setting value, the electrothermal tubes outage in the auxiliary heater 24 made heater 24 quit work; In addition,, also can start 24 pairs of water of auxiliary heater separately and heat when air compressor machine 1 is not worked, very convenient.
Referring to Fig. 1, be connected with temperature sensor 25 by water pipe 6 between water tank 4 warm water water inlets and the auxiliary heater 24, when inflow temperature is crossed when low or too high, induced signal is sent to control system 26, automatically the work of control auxiliary heater 24, be specially electrothermal tube energising or outage in the automatic control auxiliary heater 24, thereby adjust coolant-temperature gage.
Referring to Fig. 1, be connected with oil gas temperature sensor 23 between compressor 1 and the heat exchanger 22 and by oil gas efferent duct 5.Air compressor machine 1 is in service, and the oil gas temperature can not be low excessively, but can not be too high, when the oil gas temperature was lower than 65 ℃, machine oil can produce emulsification, thereby influenced the operation of air compressor machine 1, when the oil gas temperature was higher than 95 ℃, air compressor machine 1 load increased, thereby influenced the service life of air compressor machine 1.When oil gas temperature sensor 23 was sensed the oil gas temperature and is lower than 65 ℃, induced signal was sent to control system 26, and the automatically controlled water pump 21 that is connected with heat exchanger 22 is shut down, and no longer carries warm water in the heat exchanger 22; When the oil gas temperature rose to 85 ℃, induced signal was sent to control system 26, and the automatically controlled water pump 21 that is connected with heat exchanger 22 is restarted, and carries warm water in the heat exchanger 22 again, made the also no longer corresponding rising of oil gas temperature.
Finally drawn the design parameter (seeing Table 2) of the residual heat of air compressor thermal efficiency (seeing Table 1) and air compressor machine the best by experiment
The design parameter of table 1 air compressor machine the best
