Natural gas efficient-refrigerating device

Abstract

The invention discloses a natural gas efficient-refrigerating device. The natural gas efficient-refrigerating device comprises a cooling water unit module, a gas turbine module and a smoke type lithium bromide module. The cooling water unit module comprises a compressor, a condenser and an evaporator. The gas turbine module comprises a gas turbine, and an output shaft of the gas turbine is connected with a power input shaft of the compressor and drives the compressor to operate. The smoke type lithium bromide module comprises a generator, a heat exchanger, an absorber, a condenser, an evaporator, a solution pump and a working medium pump, wherein the generator is connected with an exhaust pipeline of the gas turbine, heat is supplied to the generator through smoke exhausted by the gas turbine so as to heat a lithium bromide aqueous solution, and the generator is connected with the exhaust pipeline of the gas turbine through a flue. The cooling water unit module, the gas turbine module and the smoke type lithium bromide module are integrated and mounted in a container to form a package. According to the natural gas efficient-refrigerating device, power consumption is low, and the refrigerating efficiency is high; and the cooling water unit module, the gas turbine module and the smoke type lithium bromide module are integrated into the package, so that mounting and transporting are more convenient.

Description

technical field [0001] The invention relates to the technical field of natural gas refrigeration, in particular to a high-efficiency natural gas refrigeration device. Background technique [0002] With the continuous improvement of the quality of life, the demand for cooling loads is increasing. In the prior art, large cooling loads are mainly provided by chillers and direct-fired lithium bromide. [0003] However, both of these two cooling methods have certain deficiencies. The chiller needs to be powered by electric energy to drive the compressor to complete the cooling, which consumes a large amount of high-quality and expensive electric energy; The efficiency is relatively low, and the COP is only about 1.3. [0004] Therefore, there is an urgent need for a new type of device that can efficiently utilize natural gas for refrigeration, reduce dependence on high-quality and expensive electric energy, and have relatively high refrigeration efficiency.
