Description
Technical field
The present invention relates to air compressor field, particularly relate to a kind of centrifugal air compressor of the atm number with self-cleaning filter.
Background technique
Centrifugal air compressor is the conventional equipment in air compressor field, and its working principle is by impeller to gas work done, in the runner of impeller and Diffuser, utilize centrifugal boosting and reduction of speed diffusion action, mechanical energy is converted to the pressure energy of gas.More generally, gas is when flowing through the impeller of centrifugal compressor, the impeller run up makes gas under the influence of centrifugal force, pressure increases on the one hand, speed also greatly increases on the other hand, and namely first the mechanical energy of prime mover is static energy and the kinetic energy of gas by impeller by centrifugal compressor.After this, gas is when flowing through the passage of Diffuser, and cross section of fluid channel increases gradually, molecular flow of gas prompt drop is above low, gas molecule below constantly shoves forward, makes most kinetic energy of gas change static energy into again, namely plays the effect of supercharging further.
As shown in Figure 1, centrifugal air compressor import conventional at present and outlet all arrange filter, and the metre filter area of machine import is less, cause filter life shorter, every three months needs to change once, and spare part has costly, increases very large cost of production to enterprise; After machine exit arranges filter, because its precision is often higher than centrifuge inlet filter precision, therefore filter differential pressure can progressively increase, and along with pressure reduction progressively increases, centrifuge exhaust pressure can increase, there is emptying, cause air demand to decline, energy waste is very large, for ensureing gas consumption, within every two months, just need replacing filter element, cost is very high.
There is centrifugal air compressor 6 in certain company, total air demand 1100Nm
3/ min, centrifuge import is the original-pack plate filter of import, filter precision 2 microns, filter area 2m
2, machine exit arranges 1 micron of piping filter.Because machine inlet filter area is less, every three months needs replacing filter, and import spare part unit price is 10,000 yuan/cover, and year produces expense about 200,000 yuan; Machine exit is provided with filter, and because filter differential pressure increases, result in air demand and decline, but centrifuge but has certain emptying, energy waste is very large, and in order to ensure air demand, change filter element twice every month, annual cost is about 300,000.
In sum, enterprise urgently wishes to reduce the cost payout produced owing to frequently changing spare part, realizes cost and reduces, thus increase the benefit.
Summary of the invention
In order to help enterprise to reduce owing to being frequently tired of the cost changed spare part and produce, the invention provides a kind of centrifugal air compressor to the atm number that filter is transformed.
For achieving the above object, technological scheme provided by the present invention is: a kind of centrifugal air compressor of atm number, comprise suction port, centrifugal air compressing device and outlet pipe, described suction port is arranged on centrifugal air compressing device, and suction port place is provided with self-cleaning filter, described outlet pipe is connected with centrifugal air compressing device.
Further, described outlet pipe is connected with storage tank.
Further, self-cleaning filter is provided with back-blowing device, described back-blowing device comprises source of the gas and solenoid valve, and described source of the gas is provided with solenoid valve.
Further, described source of the gas is for being clean air, and described clean air pressure is 0.8MPa, and dew point is-40 DEG C.
Further, described air inlet section amasss as 40m
2.
Further, described self-cleaning filter filter area is 30m
2-50m
2, filter precision is less than 2 microns.
Further, described self-cleaning filter filter area is 40m
2, filter precision is 1 micron.
Further, described self-cleaning filter forms by organizing filter cylinder more, and described filter cylinder filter area is 2m
2, filter precision is 1 micron, and is provided with back-blowing device in filter cylinder.
Further, described filter cylinder is 20,4 × 5 arrangements.
Further, described back-blowing device comprises source of the gas and solenoid valve, and described source of the gas is clean air, and described clean air pressure is 0.8MPa, and dew point is-40 DEG C, and described source of the gas is provided with solenoid valve.
Adopt technique scheme, the invention has the beneficial effects as follows:
1. by being transformed by centrifugal air compressor import plate filter, adopt large filter area, high-precision filter, machine import filter precision increases, and can ensure air demand.
2. the filter of cancelling, avoids filter differential pressure, saves the filter apparatus of outlet and the expense of spare part, greatly reduces enterprise operation cost.
3. adopt the filter of large size band blowback, filter core is increased working life, and the frequency of changing core can be reduced to several years once, greatly reduces the expense changed required for spare part, improves the economic benefit of enterprise.
4., owing to have employed the self-cleaning strainer of band blowback, online blowback, ensure that filter differential pressure rises and control in suitable scope, ensure that centrifuge operating conditions is good.
