The multistage double-screw air compressor comprises a first mainframe, a first intermediate cooling device provided with a cooling medium inlet and a cooling medium outlet, and a second mainframe, wherein the first intermediate cooling device is arranged above the first mainframe, an air outlet of the first mainframe is communicated with a high temperature air inlet of the first intermediate cooling device, the second mainframe is arranged above the first intermediate cooling device, and a low temperature air outlet of the first intermediate cooling device is communicated with a medium pressure air inlet of the second mainframe; the first mainframe and the second mainframe respectively comprise a volute, a male screw arranged in the volute and a female screw matched with the male screw, and the male screw is connected with a main motor through a driving member. In a compression process of the multistage double-screw air compressor provided by the utility model, air is firstly cooled by the first intermediate cooling device and is compressed to a preset pressure by the second mainframe, so that energy consumption needed in the compression process is greatly reduced to meet the energy saving and emission reduction demands.
Description
Technical field
The utility model relates to a kind of twin-screw air press, is specifically related to a kind of multistage twin-screw air press.
Background technique
Screw rod air press is a kind of important equipment, and purposes is very extensive.
The multistage screw air compressor of tandem, it is a kind of form of screw air compressor, be widely used because compact structure, transmission efficiency are high, disclose an a kind of series type multi-stage screw compressor that does not have the axle envelope as Chinese patent application numbers 201210193035.2, it has solved that existing series type multi-stage screw compressor easily leaks and compression pressure big problem inadequately.This does not have the series type multi-stage screw compressor of axle envelope, comprise the some platform independent compression main frames composition that is connected in series, compression main frames at different levels have separately housing alone, the volume of the compression main frame of series connection at different levels reduces from front to back successively, the screw axis of adjacent compression main frame connects transmission by the transmission joint part, link together by Sealing between the housing of adjacent compression main frame, the bottom of flange tube is provided with an oil return through-hole, and oil return through-hole is connected with the suction port of previous stage main frame.It is in series by the compression main frame of many platform independent, is convenient to daily maintenance, and wherein the volume of previous stage main frame can be realized multistage supercharging effectively greater than back one-level main frame, thereby the exhaust pressure of one-level main frame is greater than the previous stage main frame after making.Its compact structure, no risk of leakage.
But, no matter be that existing double-screw compressor and application number are the series type multi-stage screw compressor of the 201210193035.2 no axle envelopes that disclose, all ignored an important problem: gas is in compression process, when the pressurized gas that the gas under the normal pressure is compressed to certain pressure, as when adopting present compressor to compress, compression process does not have heat to remove, be a kind of adiabatic compression, under the certain situation of compression ratio, be a kind of compress mode of consumed energy maximum, do not meet the requirement of present energy-saving and emission-reduction.
The model utility content
The purpose of this utility model provides a kind of multistage twin-screw air press that has middle cooling mechanism, has above-mentioned defective to overcome prior art.
The multistage twin-screw air press of cooling mechanism in the middle of described in the utility model having comprises first main frame, is provided with first intercooler unit and second main frame of cooling medium entrance and cooling medium outlet;
Described first intercooler unit is arranged on first main frame top, the gas outlet of first main frame is connected with the high-temperature gas entrance of described first intercooler unit, described second main frame is arranged on the top of described first intercooler unit, and the cryogenic gas outlet of first intercooler unit is connected with the medium pressure gas entrance of described second main frame;
Described first main frame and second main frame comprise spiral case and the female screw that is arranged on the positive screw rod in the spiral case and cooperates with positive screw rod, and described positive screw rod is connected by dirivig member with main motor.
The beneficial effects of the utility model are: after air is compressed to certain pressure through first main frame, the high-temperature gas that obtains, cool off through first intercooler unit earlier, and then be compressed to predetermined pressure by second main frame, the needed energy consumption of whole compression process, to reduce greatly, meet the requirement of energy-saving and emission-reduction.
