Rotational flow padding type lithium bromide concentration device

Abstract

The invention discloses a rotational flow padding type lithium bromide concentration device. A transitional section is arranged inside a tube type heat exchanger to divide the shell pass of the heat exchanger into an upper section and a lower section. The lower end of the tube pass of the heat exchanger is connected with a diluted lithium bromide inlet pipe, and the upper end of the tube pass of the heat exchanger is connected with a diluted lithium bromide outlet pipe which is tangent to the cylindrical face of a hydrocyclone cavity. A hydrocyclone is of a cavity structure with the upper end being cylindrical and the lower end being conical. The outer surface of the hydrocyclone is provided with a heating jacket, the lower portion of the heating jacket is provided with a heat source inlet pipe, and the upper portion of the heating jacket is provided with a pipeline communicated with a heat source outlet pipe through the upper shell pass of the tube type heat exchanger. The upper end of the hydrocyclone is communicated with a vacuum condenser through a central tube, the lower end of the hydrocyclone is communicated with a shower pipe inside an evaporator, a sieve plate is arranged below the shower pipe, and padding capable of increasing the superficial area is placed on the sieve plate. The rotational flow padding type lithium bromide concentration device is designed for improving the heat exchanging efficiency, increasing the lithium bromide superficial area and improving the concentrating efficiency, and the rotational flow padding type lithium bromide concentration device is wide in application range.

Description

technical field [0001] The invention relates to a lithium bromide concentration device, in particular to a swirling flow packing type lithium bromide concentration device. Background technique [0002] The lithium bromide concentration device is one of the core components of the thermal energy refrigeration and air-conditioning system. The lithium bromide concentration device is also called a generator in the thermal energy refrigeration and air-conditioning system. [0003] Most of the existing lithium bromide concentration devices are heated by high-grade heat sources such as steam, so the heat transfer efficiency and evaporation surface area of ​​lithium bromide concentration devices are not high. Due to the use of high-grade heat sources such as steam for heating, the heat transfer efficiency of lithium bromide concentration devices is not high. And under the situation that evaporation surface area is less, also can obtain higher evaporation efficiency, has hindered the ...

Problems solved by technology

However, because the tail heat is a low-grade heat source and the heat source is unstable, there are high requirements for the heat transfer efficiency and evaporation surface area of ​​the lithium bromide concentration device. The existing lithium bromide concentration device cannot adapt to the use of tail heat to heat and concentrate lithium bromide. needs
