With the progress of economy and technology, the comprehensive utilization of C4 becomes more and more important in the industry, and the production process of high value-added products taking C4 as a raw material is more and more diversified. The demand for alkylate and MTBE is increasing and more manufacturers are beginning to conduct the deep processing of carbon four.

A heat pump is a device that transfers the heat energy of a low temperature heat source to a high temperature heat source, and the low temperature heat source generally used in the heat pump device is the medium around us-air, river water, sea water, municipal sewage, surface water, underground water, reclaimed water, fire pool, or the working medium discharged from industrial production equipment, and the working medium has a temperature close to the temperature of the surrounding medium.

In order to optimize the product structure of the carbon four mixed material and part of light carbon four in the residual carbon four of the MTBE device byproduct, a heat pump compressor is required.

(2) the lower shell of the compressor is fixed on the support, and an air inlet duct and an air outlet duct are arranged below the lower shell of the compressor;

(3) the number of the compressor impellers is 2-4, the diameters of the impellers are 400-800 mm, the arrangement form of the impellers on the main shaft is in a sequential arrangement, and the balance disc is arranged on one side with high pressure;

(4) the blades are of a backward bending type constant-strength structure, the blades and the hub are integrated, and the blades and the wheel disc are connected by adopting a welding structure;

(5) the diffuser adopts a vane diffuser;

(6) each stage of partition board is matched and fixed with a spigot on the shell;

(7) the support bearing adopts a tilting pad bearing, the two sides of the main shaft adopt the same structure, and the thrust bearing is of a Kimberley type.

The utility model discloses a heat pump compressor, the impeller of saying is arranged in the same direction as arranging in the epaxial arrangement form of main shaft, and the balance disc is arranged in the one side that pressure is high, and the axial thrust that can effectual reduction gas to rotor production makes the operation of whole set of unit more steady.

The utility model discloses a heat pump compressor provides specific user and makes light hydrocarbon comprehensive utilization project carbon four-combined-device complete sets use, has gained very ideal effect. And the system is used as non-standard equipment for supplying users who sign a confidential contract, and the system obtains the favorable comment of the users.
