A compressed air feed system used for supplying compressed air for the operation of a moving bed filter comprises a compressor (11) and a conduit (12) connecting the compressor with the moving bed filter, wherein the compressor adopts a variable-speed compressor. About 50 percent of energy can be saved by using the system.
Description
Technical field
The utility model relates generally to a kind of compressed-air supply system, and it is used to operate particle layers filter and/or moving bed reactor, and is used in particular for operating the air lift in this filter.
Background technique
Moving bed filter is widely used in water treatment and sewage treatment.The granule medium filter bed of this moving bed filter (to call " filter bed " in the following text) is transferred device and remains slow motion, described feedway often is delivered to from the bottom of filter bed particulate filter medium the top of filter bed via the washing machine (so-called medium washing machine) of particulate filter medium, in the medium washing machine, described particulate filter medium is washed to remove isolated impurity in moving bed filter.
The example of moving bed filter is found in the U. S. Patent that the patent No. is US 6426005B1, US 4126546, US 4197201 and US 4246102, and above-mentioned patent is incorporated herein by reference.
One or more air lift is often used as above-mentioned feedway.Use pressurized air operation air lift.In principle, air lift is the pipeline that impregnated in the liquid that may contain particle, and the intake section of this pipeline is in than the lower level position of exit portion, and pressurized air is being introduced near the entrance part office.Because the mixture of the air/liquid/particle in the air lift has than liquid or the lower density of liquid-solid mixture on every side, therefore cause the suction behavior.
Air lift provides the easy instrument of the liquid that a kind of conveying contains particle, and its running cost depends primarily on described compressed-air actuated cost.This cost depends on air pressure and air velocity (for example volume of unit time).The air pressure factor has the greatest impact to the running cost of air lift.
Traditionally, compressor can provide the air pressure that is generally 7bar usually, and blower is operated under the air pressure of about 1bar.Because the underpressure in the blower is traditional compressor with the air lift in the operation moving bed filter so be used for the common tool of this operation.To be directly used in the operation of air lift the moving bed filter from the pressurized air that this compressor is discharged, therefore its overpressure before being used to air lift, reduces pressure to this pressurized air.Thisly at first produce the practice that high pressure reduces pressure then caused undesirable energy loss before using pressurized air.
The reason that causes this operation is because lack the proper compression machine that the pressure between the mistake low pressure of crossing high pressure and blower that is in traditional compressor can be provided.
Along with the appearance of the compressed-air actuated intermediate pressure compressor (for example Alcula type compressor) that can produce 2.2bar for example (promptly than conventional compressor low but than blower height), this situation has obtained change.Be suitable for the operation of moving bed filter through the compressed-air actuated pressure of intermediate pressure compressor conveying.
But, be that problem has also appearred in the operation that this intermediate pressure compressor replaces conventional compressor to be used for moving bed filter unexpectedly.For example, in the moving bed filter system that uses conventional compressor, adopt a kind of like this mode to control compressor usually, compressor enters the pressurized air suction in the air reservoir, and this storage tank is sent air into filter system.Described compressor can be operated under the ON/OFF pattern by a kind of like this mode,, sets high-pressure horizontal and low pressure level that is, and when the air pressure in the storage tank reached high pressure, compressor was closed, and when the air pressure in the storage tank reached low pressure, compressor started again.If intermediate pressure compressor replaces conventional compressor operating, this system is with ineffective.The pressure of intermediate pressure compressor approaches the required pressure of air lift, therefore can not adopt the system identical with conventional compressor, because in order to the on/off operation of control compressor or cause frequent unlatching and stop, this will be unfavorable for compressor, and will be perhaps low excessively for the operation of air lift for the set low pressure of the unlatching of compressor.
Use intermediate pressure compressor also can cause system extremely sensitive to the condensed water in the compressed air line.This condensed water and low pressure will cause system to move jointly.
