Our innovative heat pump distillation employs the sophisticated process of elevating and heating the steam at the tower's peak, driven by external power. This advanced technique transforms it into a higher-grade energy source, serving as the reboiler's heat source at the base of the tower. This ingenious method effectively recaptures the latent heat of the steam from the tower's summit, enhancing efficiency and sustainability.
The direct compression heat pump distillation ingeniously utilizes the tower top vapor phase as its principal working fluid. By channeling through an external steam compressor, it elevates the energy level of this vapor phase, transforming it into a high-temperature heat source for the tower bottom reboiler. As illustrated in the accompanying figure, this advanced methodology is ideally suited for separation systems where temperature differences are minimal and boiling points are closely aligned between the tower's apex and base.
Our centrifugal compressor, designed for heat pump distillation, incorporates a comprehensive array of components including the compressor body, coupling, gearbox, lubrication system, motor, electric instrument, and an anti-surge control system. Its design is remarkably compact, ensuring ease of maintenance and operational convenience.
Experience the revolutionary efficiency of our compressors, which entirely negate the need for external heat sources and cooling water, optimizing your operations like never before!
3.3.1 The compressor base is integrally placed on the foundation, put wedge-shaped shim under the base (used to adjust the unit level),
place two wedge-shaped irons alternately, after leveling the unit, and spot weld the wedge-shaped irons for 4~5 points. The wedge shall be
manufactured and installed by the user according to the actual situation, and the contact surface shall be finished (even contact of inclined
plane, and the bearing capacity of wedge iron shall not be greater than 40Kg/cm2).
3.3.2 Use a level to find the level. The leveling requirements of the unit: the axial level of the unit is 0.05/1000mm, and the horizontal
level of the unit is 0.10/1000mm.
3.3.3 Coupling is centered. Before starting alignment, confirm the following requirements:
1) Turn off the main power supply;
2) Remove the coupling shield;
3) Remove the diaphragm coupling intermediate section;
4) Check the flatness of the motor installation plane to ensure that there are no stolen goods, dirt and attachments;
5) The motor bolt hole should be larger than the bolt size, so that the bolt can be loosened to adjust the motor;
6) Prepare enough stainless steel gaskets to cover the foot of the motor, the gaskets should not have attachments and should be flat enough. You cannot use long and thin gaskets to insert between the motor and the base for adjustment;
7) Use a dial indicator or a laser alignment meter with an accuracy of 0.01mm (prepared by the customer himself);
8) Prepare the bracket for supporting the dial indicator as shown in the figure below;
9) The motor wheel hub mounting bracket is used for mounting a dial indicator on the edge of the wheel hub, and placing a dial indicator probe on the outer edge of the compressor wheel hub;
10) By adjusting the adjustment bolts around the motor feet, the compressor and the motor center line are basically on the same line (or according to the corresponding instructions), and the maximum deviation of the outer circle is 0.05mm (the motor shaft center line should be higher than the compressor low-speed shaft center line), coupling end face 0.03~0.05mm;
11) Finally, tighten the motor foot bolts, and review the outer circle runout and end face runout of the coupling;
12) Install the coupling intermediate section after the motor idling test.
3.3.4 After adjusting the "levelness" and alignment of the casing, tighten the anchor bolts. After the mechanical operation (or trial operation), loosen the bolts and tighten them again.
3.3.5 The impeller is a high speed rotating component, and any solid or liquid entering impeller will cause irreversible damage to compressor. Therefore, it is necessary to ensure that the inlet and outlet pipelines connected with compressor are clean and meet the requirements of steam corrosion grade of the system. Pipelines that do not meet this condition must be rectified. It is suggested to add solid liquid separation equipment (gas scrubber or sedimentation tee) before the straight pipe at the compressor inlet.
3.3.6 Install compressor inlet and outlet pipes. Import and export pipelines shall be installed with relevant pipeline accessories according to PI diagram. The pipeline connected to the compressor shall be supported by another bracket, and its weight shall not be supported by the compressor body.
3.3.7 Once the main fan along with its supporting equipment is securely installed and the concrete has fully cured, it's time to perform the compressor operation test. This critical step ensures that your Methanol Compressor Featuring Overall Base and Speed Regulation Technology from NANTONG DART-RICH FAN CO., LTD is ready to deliver optimal performance.
3.3.8 For seamless operation, the compressor's electric control cabinet should be strategically installed within a 5-meter radius of the compressor. The wiring, elegantly concealed underground in threading pipes, connects the compressor to the control cabinet. Once the cabinet is perfectly positioned, join the wiring terminals within the electric control cabinet to the remote DCS lines, ensuring flawless integration and control of your cutting-edge Methanol Compressor Featuring Overall Base and Speed Regulation Technology.
