(1) technical field
The utility model relates to a kind of steam double-effect lithium bromide absorption type handpiece Water Chilling Units.Belong to air conditioner technical field.
(2) background technology
At present solution series flow process steam double-effect type lithium-bromide absorption-type refrigerating machine group such as Fig. 1, the pipeline, the valve that are coagulated aqueous solution heat exchanger 7, solution pump, cryogenic fluid pump, control system (not shown) and connected each parts by high pressure generator 1, low pressure generator 2, condenser 3, evaporimeter 4, absorber 5, high-temperature solution heat exchanger 8, cryogenic fluid heat exchanger 6, working steam are constituted.The absorber weak solution is connected after solution pump boosts and is entered cryogenic fluid heat exchanger 6 successively, working steam coagulates aqueous solution heat exchanger 7 and high-temperature solution heat exchanger 8.Because enter the heating that weak solution that working steam coagulates aqueous solution heat exchanger 7 has been passed through cryogenic fluid heat exchanger 6, temperature is higher, causing working steam to coagulate water, to go out the unit temperature higher, coagulates the hydro-thermal amount and do not make full use of.The weak solution of coming out from cryogenic fluid heat exchanger 6 is coagulated aqueous solution heat exchanger 7 heat temperature raisings owing to pass through working steam in addition, enter the weak solution temperature height of high-temperature solution heat exchanger 8, cause high-temperature solution heat exchanger 8 outlet intermediate solution temperature height, the heat that intermediate solution adds weak solution reduces, and has improved the working steam consumption of unit.Refrigerant vapour occurred frequently in addition coagulates coolant-temperature gage and directly is discharged in the condenser above 90 ℃, has caused the loss of energy.How fully to reclaim the waste heat that refrigerant vapour occurred frequently coagulates water, more effectively utilize working steam to coagulate the hydro-thermal amount, reduce the steam consumption of solution series flow process steam double-effect lithium bromide absorption type handpiece Water Chilling Units, reduce operating cost, realize the mixed economy and the social benefit of energy-saving and emission-reduction, become one of important topic of present research.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of working steam that more effectively utilizes to coagulate the hydro-thermal amount, fully reclaims the high-efficiency steam double-effect lithium bromide absorption type handpiece Water Chilling Units that refrigerant vapour occurred frequently coagulates the water waste heat.
The purpose of this utility model is achieved in that
On solution series flow process steam double-effect type lithium bromide absorption cold water unit basis, set up a refrigerant vapour occurred frequently and coagulate water-to-water heat exchanger, the absorber weak solution is divided into two the tunnel after solution pump boosts, one tunnel series connection enters the cryogenic fluid heat exchanger successively and high-temperature solution heat exchanger heats up, the series connection of another road enters refrigerant vapour occurred frequently and coagulates water-to-water heat exchanger and working steam and coagulate aqueous solution heat exchanger and heat up, two tunnel weak solutions after the intensification separately or converge to and enter high pressure generator together, the low pressure generator water as refrigerant enters and enters condenser after refrigerant vapour occurred frequently coagulates water-to-water heat exchanger.Coagulate water-to-water heat exchanger by setting up refrigerant vapour occurred frequently, reclaim refrigerant vapour occurred frequently with weak solution and coagulate the water waste heat, reduce steam consumption quantity, reduce condenser duty, save cooling water indirectly.It is in parallel with the high and low temperature solution heat exchanger that refrigerant vapour occurred frequently coagulates water-to-water heat exchanger, cryogenic fluid heat exchanger outlet weak solution directly enters high-temperature solution heat exchanger, coagulating water heat exchanger without working steam heats up, temperature is lower, the temperature that intermediate solution goes out high-temperature solution heat exchanger descends, the heat that intermediate solution adds weak solution increases, and fully reclaims the unit internal heat, has reduced the working steam consumption.
The beneficial effects of the utility model are:
By the optimization of above solution flow process, can reduce working steam consumption about 5%, reduced condenser duty simultaneously, reduce the consumption of cooling water inflow, reduce operating cost, realize the mixed economy and the social benefit of energy-saving and emission-reduction.
