Overhauling device capable of treating lithium bromide solution in lithium bromide absorbing unit on site

Abstract

The invention discloses an overhauling device capable of treating a lithium bromide solution in a lithium bromide absorbing unit on site. The overhauling device comprises a self-priming pump, a filter, a reaction kettle and a constant temperature regulator; an outlet of the self-priming pump communicates with an inlet of the filter; an outlet of the filter communicates with an inlet of the reaction kettle; a solution concentration meter which is used for detecting and displaying the concentration of the solution in the reaction kettle in real time is arranged outside the reaction kettle; a solution thermometer and a steam heat exchanger are arranged in the reaction kettle; the solution thermometer is used for acquiring the temperature of the solution in the reaction kettle in real time andtransmitting the acquired solution temperature signal to the constant temperature regulator in real time; the steam heat exchanger is used for heating the solution in the reaction kettle; an inlet ofthe steam heat exchanger communicates with a steam source through a steam regulating valve; and the constant temperature regulator is used for receiving the solution temperature signal which is transmitted by the solution thermometer in real time and controlling and regulating the steam regulating valve. The overhauling device has the advantage of capacity of treating the polluted low-concentration lithium bromide solution in the lithium bromide absorbing unit on site.

Description

technical field [0001] The invention relates to the field of maintenance of lithium bromide absorption type units, in particular to an overhaul device capable of on-site processing of lithium bromide solution in lithium bromide absorption type units. Background technique [0002] During the use of lithium bromide absorption units, the most frequent and harmful fault is the internal leakage of the system. Because the inner cavity of the lithium bromide absorption unit is a vacuum environment, once the unit leaks, the chilled water and cooling water in the absorber, condenser, and evaporator will pollute the lithium bromide solution in the lithium bromide absorption unit in a very short time And dilution, the lithium bromide absorption unit instantly loses its cooling capacity. At present, when the lithium bromide absorption unit is overhauled on site, all the contaminated and diluted solutions must be extracted for concentration testing. Once the concentration is lower than ...

AI Technical Summary

Problems solved by technology

Because the inner cavity of the lithium bromide absorption unit is a vacuum environment, once the unit leaks, the chilled water and cooling water in the absorber, condenser, and evaporator will pollute the lithium bromide solution in the lithium bromide absorption unit in a very short time and dilution, so that the lithium bromide absorption unit loses its refrigeration capacity instantly

At present, when the lithium bromide absorption unit is overhauled on site, all the contaminated and diluted solutions must be extracted for concentration testing. Once the concentration is lower than 20%, on-site treatment cannot be carried out, and new solutions can only be purchased. Fill the lithium bromide absorption unit with new solution after repairing the leakage point

Taking the existing 16DE866 unit as an example, the solution charging volume is 3000KG, and the current price of 55% lithium bromide solution is 50 yuan / KG. It takes 150,000 yuan to charge the whole machine once, and it takes 12 hours to extract the contaminated solution during actual operation. It takes 6 hours to fill the new solution, which does not include the time of purchasing the solution and shipping

Since the seriously polluted low-concentration lithium bromide solution cannot be treated on site, it not only reduces the maintenance efficiency of lithium bromide absorption units, but also causes large economic losses
