The air compressor firstly dehumidify air therein in advance so that low air inflow temperature is low, air inflow area is large, low compressor energy consumption is low, small noise is small and reliability is greatly improved.
Description
Technical field
The invention belongs to the air compressor technical field, be specifically related to a kind of air inlet lyophilisation air compressor unit.
Background technique
In the prior art, at present the pressurized air lyophilisation mode air that uses cools off after by compressor compresses, by refrigerator pressurized air is carried out dehumidification treatments again, reaches the requirement that the user uses.Specifically as shown in Figure 1, after air at first compressed by compressor, the compressor rear end was connected with oil separator, is connected with air radiator, refrigerator on the oil separator in turn, carry out dehumidification treatments by the refrigerator water of condensation, the dry pressurized air in back that will dehumidify then offers the user.
The cryodesiccated mode of this kind air compressor pressurized air is to prolong the mature technology of promoting with for many years, in enormous quantities, but this kind processing mode exists following defective:
(1) intake temperature is an ambient temperature, the temperature after the air compression up to 140 the degree more than, the temperature height.
(2) energy consumption is bigger, and the specific power of middle-size and small-size air compressor is at 6.5kw/m
3About.
(3) noise height easily causes noise pollution.
(4) reliability is low, when the high humidity of air, water loading of the air is many, temperature height when air is compressed and stops, this moment, lubricant oil was easy to generate decomposition, can produce carbon distribution at some key positions of compressor, make the operation of compressor produce fault, thereby the maintenance rate height of air compressor, the maintenance cost height, reliability reduces greatly.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of air inlet lyophilisation air compressor unit is provided, this air compressor is owing to the air that will enter in the air compressor earlier dehumidifies in advance, make intake temperature low, the air inlet area increases, make that energy consumption of compressor is low, noise is little, reliability improves greatly.
In order to solve the problems of the technologies described above, the present invention realizes by the following technical solutions:
Air inlet lyophilisation air compressor unit of the present invention, comprise air compressor, front end air ingress at air compressor is connected with cooling machine set, the compressed air outlet end of described air compressor is connected with oil separator and air radiator in turn, and described air radiator end is given the user by connecting tube with the compressed air delivery of drying.
In the present invention, described cooling machine set comprises refrigeration compressor, condenser, expansion valve, the vaporizer that connects successively by connecting tube.Its working principle is: refrigeration compressor provides the refrigerant vapour of energy to low-temp low-pressure, and the gas that becomes High Temperature High Pressure behind the refrigerant vapour acquisition energy of low-temp low-pressure is supplied with condenser; The gas of the High Temperature High Pressure that condenser is supplied with refrigeration compressor externally becomes the liquid of high normal pressure and temperature after the heat radiation, and liquid that then will this high normal pressure and temperature is supplied with expansion valve, becomes the liquid supply vaporizer of low-temp low-pressure behind the expansion of liquids of expansion valve with high normal pressure and temperature; Vaporizer makes that by the air inlet heat that absorbs air compressor the intake temperature of air compressor reduces, humidity reduces with the liquid of low-temp low-pressure again, remove moisture and use the gas requirement with what reach the user, the steam supply system cold compressor that makes refrigeration agent become low-temp low-pressure simultaneously absorbs the circulation of carrying out once more.
As the further improvement of above-mentioned technology, described vaporizer below is provided with one and is used to collect the condensate drain pan of water of condensation.
In the present invention, for the degree of dryness and the drying efficiency that improve dried compressed air, the outlet of the dried compressed air of described vaporizer is provided with device for drying and filtering and blower.
In the present invention,, also be provided with temperature controller, humidity controller on the described cooling machine set, also comprise control electric consumer components and parts in order to control temperature, humidity in real time.
Compared with prior art, beneficial effect of the present invention:
(1) the present invention is owing to place the position of the suction port of air compressor with cooling machine set, makes the intake temperature of air compressor than more than low 20 degree of ambient temperature, make the exhaust outlet temperature can be controlled at 120 spend in, temperature is lower;
(2) the present invention is because air enters air compressor preceding compression refrigeration and dehumidifying by cooling machine set, promptly entering the preceding temperature of air compressor reduces, thereby air density increases, make the gas transmission efficient of air compressor improve, energy consumption of compressor reduces, and the specific power of air compressor reduces more than 5%, energy-conservation more than 5%, displacement increases more than 3%, and is energy-saving and cost-reducing, good environmental protection.
(3) the present invention has reduced intake velocity owing to increased the air inlet area of air, makes noise reduce more than the 3dB (A), has reduced noise pollution widely.
(4) among the present invention, after entering the temperature and moisture reduction of air compressor, having significantly reduced the lubricant oil knot carbon phenomenon that adopts in the air compressor takes place, make the mean time between failures (MTBF) of product be brought up to more than 20000 hours by 8000 hours of prior art, its reliability improves greatly.
