Abstract
The invention relates to a high-air-capacity centrifugal air compressor. The high-gas-capacity centrifugal air compressor comprises an air inlet, a centrifugal air compressing device and an air outlet pipeline, wherein the air inlet is formed on the centrifugal air compressing device, a self-cleaning filter is arranged at the air inlet, and the air outlet pipeline is connected with the centrifugal air compressor. The high-gas-capacity centrifugal air compressor also comprises a high-air-capacity centrifuge which comprises an online back flushing filter with a large air inlet filtering area. The filter replaces a frame type filter with a small air inlet filtering area of the conventional centrifuge, and an outlet pipeline filter is removed. The high-air-capacity centrifugal air compressor overcomes the defects of high spare part cost, machine group idling and serious energy waste because the filtering area of an inlet filter of a machine and the pressure difference of the filter rises quickly. The high-air-capacity centrifugal air compressor reduces the cost and improves the economical benefit for enterprises.
Description
Technical field
The present invention relates to the air compressor field, particularly relate to a kind of centrifugal air compressor that has the atm number of self-cleaning filter.
Background technique
Centrifugal air compressor is an air compressor field equipment commonly used, its working principle be through impeller to the gas work done, in the runner of impeller and Diffuser, utilize centrifugal boosting and reduction of speed diffusion action, mechanical energy is converted into the pressure ability of gas.More generally; Gas is when flowing through the impeller of centrifugal compressor; The impeller that runs up makes gas under action of centrifugal force; Pressure increases on the one hand, and speed also greatly increases on the other hand, and promptly centrifugal compressor at first changes the mechanical energy of prime mover into the static energy and the kinetic energy of gas through impeller.After this, gas is when flowing through the passage of Diffuser, and cross section of fluid channel increases gradually; The molecular flow of gas prompt drop of front is low; The gas molecule of back constantly shoves forward, makes most kinetic energy of gas change static energy again into, just further plays the effect of supercharging.
As shown in Figure 1, centrifugal air compressor import commonly used at present all is provided with filter with outlet, and the filter filter area of machine import is less; Cause filter life shorter; Every three months need be changed once, and spare part has comparison expensive, increases very big cost of production to enterprise; After machine exit was provided with filter, because its precision often is higher than centrifuge inlet filter precision, so filter pressure reduction can progressively increase; Along with pressure reduction progressively increases, the centrifuge exhaust pressure can increase, and emptying occurs; Cause air demand to descend, energy waste is very big, for guaranteeing gas consumption; Just needed in per two months to change a filter element, cost is very high.
There are 6 of centrifugal air compressors in certain company, total air demand 1100Nm
3/ min, the centrifuge import is the original-pack plate filter of import, 2 microns of filter precisioies, filter area 2m
2, machine exit is provided with 1 micron piping filter.Because machine inlet filter area is less, every three months need be changed filter No. one time, and import spare part unit price is 10,000 a yuan/cover, about 200,000 yuan of contracts expense; Machine exit is provided with filter, because filter pressure reduction increases, caused air demand decline, but centrifuge but has certain emptying, and energy waste is very big, in order to guarantee air demand, changes filter element twice every month, and annual cost is about 300,000.
In sum, the urgent hope of enterprise can reduce because the cost expenditure that the frequent change spare part is produced realizes that cost reduces, thereby increases the benefit.
Summary of the invention
Owing to tiredly frequently change the cost that spare part produced, the invention provides a kind of centrifugal air compressor of the atm number that filter is transformed in order to help enterprise to reduce.

Further, said suction port sectional area is 40m
2
Further, said self-cleaning filter filter area is 30m
2-50m
2, filter precision is less than 2 microns.
Further, said self-cleaning filter filter area is 40m
2, filter precision is 1 micron.
Further, said self-cleaning filter is made up of many groups filter cylinder, and said filter cylinder filter area is 2m
2, filter precision is 1 micron, and is provided with back-blowing device in the filter cylinder.
Further, said filter cylinder is 20, and 4 * 5 arrange.
Further, said back-blowing device comprises source of the gas and solenoid valve, and said source of the gas is a clean air, and said clean air pressure is 0.8MPa, and dew point is-40 ℃, and on the said source of the gas solenoid valve is installed.
Adopt technique scheme, the invention has the beneficial effects as follows:
1. through centrifugal air compressor import plate filter is transformed, adopt big filter area, high-precision filter, machine import filter precision increases, and can guarantee air demand.
2. the filter of cancelling is avoided filter pressure reduction, has saved the filter apparatus of outlet and the expense of spare part, greatly reduces the enterprise operation cost.
3. adopt the filter of large size band blowback, filter core is increased working life, the frequency of changing core can be reduced to several years once, has significantly reduced the needed expense of replacing spare part, improves economic benefit of enterprises.
4. owing to adopted the self-cleaning strainer of band blowback, online blowback guarantees that the rising of filter pressure reduction is controlled in the suitable scope, guarantees that the centrifuge operating conditions is good.
