Abstract
The utility model discloses a frequency conversion type screw compressor flow device. The frequency conversion type screw compressor flow device consists of two screw compressors, frequency converters and a gas storage tank, wherein the frequency converters are connected with the screw compressors; the two screw compressors are symmetrically arranged, are correspondingly connected with the frequency converters and are connected with the gas storage tank through a gas input pipeline; double gas valves are arranged on the gas input pipeline; the gas storage tank is provided with a gas input port, a gas output port, a safety valve and a pressure meter; the gas input port is connected with the gas input pipeline, and a three-way ball valve is arranged at a connection position of the gas input port and the gas input pipeline; the gas output port is connected with a gas output pipeline, and a gas supply valve is arranged at a connection position of the gas output port and the gas output pipeline. The frequency conversion type screw compressor flow device is simple in structure; by additionally arranging the two frequency converters, the loading and the unloading cannot be frequently carried out in the production flow of a unit, the unit is in a loaded state all the time, gas is steadily output and is high in gas pressure, the service life of a motor is greatly prolonged, and the production flow is easy to maintain.
Description
Technical field
The utility model belongs to Chemical Manufacture flow process technical field, and what be specifically related to is a kind of variable-frequency type helical-lobe compressor flow path device, and this device is for the production procedure of epoxychloropropane.
Background technique
Existing production procedure process of producing epoxychloropropane comprises that air compressor carries out air compressing, conveying and the gas holder of carrying gas pipeline to carry out gas carries out the storage of pressurized gas, in this traditional mode of production flow process, the plus-minus carrier frequency of its air compressor is numerous, under power frequency, plus-minus live stream is relevant large, thereby greatly affect the working life of motor, and the air pressure tolerance shakiness of its generation, power consumption is larger, and this case is given birth to therefrom.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of production process design reasonable, and produces the variable-frequency type helical-lobe compressor flow path device that air pressure tolerance meets the demands.
The utility model is achieved through the following technical solutions: variable-frequency type helical-lobe compressor flow path device, by helical-lobe compressor, the frequency variator be connected with helical-lobe compressor and gas holder, formed, described helical-lobe compressor quantity is symmetrically arranged two compositions, and all connect frequency variator on every helical-lobe compressor, be connected by the gas inlet pipe road between flypress and gas holder, and on this gas pipeline, dual air valve be installed.
Described gas holder is provided with gas input port, gas delivery port, safety valve and pressure gauge; This gas input port is connected with the gas inlet pipe road, and is provided with tee ball valve in joint, and gas delivery port is connected with the gas output tube road, and is provided with steam supply valve in joint, gas output tube road.
The beneficial effects of the utility model embody and are: prior art is compared, the utility model is simple in structure, by setting up two groups of frequency variators, make unit production stream kind can frequently not add off-load, unit is the state in loading always, and output gas is steady, and amount of gas pressure is large, electrical machinery life extends greatly, and production procedure is safeguarded simple.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in detail.
Fig. 1 is the utility model structural representation.
Following is the concrete title of each sign in figure: 1 helical-lobe compressor, 2 frequency variators, 3 helical-lobe compressors, 4 frequency variators, 5 tee ball valves, 6 pressure gauges, 7 gas output tube roads, 8 steam supply valves, 9 gas holder, 10 safety valves, 11 gas inlet pipe roads, 12 air valves, 13 air valves.
In figure, the direction of arrow means gas flow direction.
Embodiment
As shown in Figure 1, variable-frequency type helical-lobe compressor flow path device, by symmetrically arranged two helical-lobe compressors (1,3), two frequency variators (2,4) and the gas holder 9 that are connected respectively with helical-lobe compressor (1,3), formed, between flypress 1 and gas holder 9, by gas inlet pipe road 11, be connected, air valve 12 also is installed on this gas pipeline, and is connected on gas holder 9 through tee ball valve.
Be connected by gas inlet pipe road 11 between flypress 3 and gas holder 9, on this gas pipeline 11, air valve 13 also be installed, and be connected on gas holder 9 through tee ball valve.
Gas holder 9 is provided with gas input port, gas delivery port, safety valve 10 and pressure gauge 6; This gas input port is connected with gas inlet pipe road 11, and is provided with tee ball valve 5 in joint, and gas delivery port is connected with gas output tube road 7, and is provided with steam supply valve 8 in 7 joints, gas output tube road.
Air is through the compression of two helical-lobe compressors, and under the control action of frequency variator, unit can frequently not add off-load therebetween, and every arranges frequency of okperation is 30HZ; Unit is always in loading a kind of state, and current of electric is constant, makes stable gas pressure, and gas production is large, and the pressurized gas of output are transported to gas holder and carry out the air pressure storage.
