Abstract

The utility model relates to a solution circulation device for a direct combustion high-pressure producer, which is composed of a vapor cover, a liquid baffle plate, a casing, a heat-transfer pipe, a hearth and a smoke window. The device is characterized in that more than two circulating pipes are arranged outside both sides of the casing, and the two pipes are communicated with the interior part of the casing through an upper hole and a lower hole on the casing. In the course of heating, the solution is capable of rapidly mixing and circulating up and down based upon the characteristic of cold/heat convection, so that the lithium bromide solution is rapidly evaporated from the water, the evaporation efficiency can be improved, and the condensation of dilute solution can be accelerated. The utility model is suitable for various direct combustion high-pressure producers.

Description

Direct-fired high pressure generator solution EGR

The utility model relates to a kind of directly burning lithium bromide refrigerator high pressure generator solution EGR.

Usually in directly burning lithium bromide refrigerator, lithium-bromide solution in the high pressure generator flows to the other end by an end outside heat-transfer pipe, by the heating of the flame in the burner hearth and the flue gas in the heat-transfer pipe and seethe with excitement, the water evaporates that bromizates in the lithium solution is come out to become refrigerant vapour and is concentrated, become concentrated solution, the shortcoming of this structure is: lithium-bromide solution just vertically flows in high pressure generator, for mixing circulation is slow up and down, to the water evaporates weak effect that bromizates in the lithium solution.

The purpose of this utility model is to overcome weak point in the prior art and a kind of direct-fired high pressure generator solution EGR that lithium solution can circulate up and down fast that bromizates is provided.

This purpose is achieved in that direct-fired high pressure generator solution EGR, constitute by vapour cover, liquid barrier, shell, heat-transfer pipe, burner hearth, smokestack, it is characterized in that being provided with two with upper circular tube in the outside, both sides of shell, and by the internal communication of hole on offering on the shell with following hole and shell.

Characteristics of the present utility model are in high pressure generator, lithium-bromide solution is carried out in the heating process, by several circulation pipes of setting up, utilize the characteristic of liquid cold and hot convection current, quick again and again mixing circulation up and down, the moisture that bromizates in the lithium solution is evaporated rapidly, improves evaporation efficiency, quickens weak solution and concentrates.

Now in conjunction with the accompanying drawings the utility model is elaborated.

Fig. 1 is the utility model structure chart;

Fig. 2 is the utility model side view.

Embodiment: the thermal source of direct-fired high pressure generator is oil firing or combustion gas, flame is in burner hearth 6 internal combustion, flue gas enters atmosphere through heat-transfer pipe 4 and smokestack 10, lithium-bromide solution 5 is in the outside of heat-transfer pipe 4, be provided with 8 in the present embodiment and follow bad pipe 7, in heating process, lithium-bromide solution 5 oneself the following holes 9 that temperature are lower in the circulation pipe 7 enter in the shell 3, top high temperature lithium-bromide solution 5 flows in the circulation pipes 7 from last hole 8, because temperature descends, oneself enters in the shell 3 in hole 9 down cryogenic fluid again, so carry out the circulation of above-below direction again and again, bromizate lithium solution 5 and quicken boiling, the water evaporates in the solution is come out and concentrate, water vapour enters in the vapour cover 1 through liquid barrier 2, and the flue gas in the heating process enters atmosphere through smokestack 10.

The utility model is applicable to the directly burning lithium bromide refrigerator high pressure generator unit of all size.
