Description
Technical field:
The utility model relates to the device that a kind of alumina producer is used to improve temperature of vaporizing raw liquor.
Background technology:
The vaporizing raw liquor of alumina producer is to send to evaporate station by raw liquor pump to evaporate in the prior art, in order to strengthen decomposition, have additional intermediate temperature drop equipment, make the temperature of vaporizing raw liquor reduce to below 80 ℃, make vaporizing raw liquor energy consumption when evaporation strengthen like this by original about 92 ℃.And the live steam condensed water of stripping, pressure is approximately 0.5Mpa, and temperature when it is sent to steam power plant's flash distillation, can cause the conveyance conduit strenuous vibration up to 158 ℃, and the direct emptying of vapours that produces, and causes the heavy losses of heat.
Summary of the invention:
The purpose of this utility model is: provide a kind of temperature of vaporizing raw liquor that can improve to reduce the evaporation energy consumption of vaporizing raw liquor, and can effectively utilize the heat of stripping steam condensate (SC), eliminate the device of the raising temperature of vaporizing raw liquor of pipe vibration, to overcome above-mentioned the deficiencies in the prior art.
The utility model is to constitute like this: it comprises raw liquor pump (1) and stripping condensate pump (2), between raw liquor pump (1) and stripping condensate pump (2), be connected with plate type heat exchanger (3) by stoste pipeline (4) and condensate pump pipeline (5), and on the stoste pipeline (4) of raw liquor pump (1), be provided with the bypass pipe (6) that the pipeline (7) that is connected with evaporate station communicates, on the liquid outlet of plate type heat exchanger (3), also be provided with the vaporizing raw liquor carrier pipe (8) that the pipeline (7) that is connected with evaporate station communicates; The condensate pump pipeline (5) of stripping condensate pump (2) go up and the condensation-water drain of plate type heat exchanger (3) on be connected with water pipe (9) and the condensate pipe (10) that the condensed water carrier pipe (11) that is connected with steam power plant is connected respectively.
Owing to adopted technique scheme, the utility model can reduce the evaporation energy consumption of vaporizing raw liquor effectively, and it has effectively utilized the heat of stripping steam condensate (SC), greatly reduces production cost.Adopting the utility model can make the temperature of vaporizing raw liquor improve 6 ℃～7 ℃, per hour can save the about 8.4t of steam of 0.6Mpa, is that 70 yuan/t calculates with the price of steam, and the whole year is with regard to cost-saved about 4,890,000 yuan.And eliminated the strenuous vibration of conveyance conduit, ensured carrying out smoothly of producing.Therefore the utility model compared with prior art, it has can energy efficient, reduce production costs greatly and avoided the advantage of the strenuous vibration of conveyance conduit.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment of the present utility model: as shown in Figure 1, raw liquor pump (1) and stripping condensate pump (2) all adopt existing equipment, during making, between raw liquor pump (1) and stripping condensate pump (2), be connected plate type heat exchanger (3) with condensate pump pipeline (5) by stoste pipeline (4), plate type heat exchanger (3) can directly adopt finished product of the prior art to install, the bypass pipe (6) that a pipeline that is connected with evaporate station (7) communicates is installed between two valves on the stoste pipeline (4) of raw liquor pump (1) then, and at by-pass valve control of the last installation of bypass pipe (6), the vaporizing raw liquor carrier pipe (8) that a pipeline that is connected with evaporate station (7) communicates also is installed on the liquid outlet of plate type heat exchanger (3), and a by-pass valve control also is installed on vaporizing raw liquor carrier pipe (8); Connecting water pipe (9) and the condensate pipe (10) that a condensed water carrier pipe (11) that is connected with steam power plant is connected respectively between two valves of the condensate pump pipeline (5) of stripping condensate pump (2) and on the condensation-water drain of plate type heat exchanger (3), and a by-pass valve control is being installed respectively on water pipe (9) and condensate pipe (10).
During the utility model work, the vaporizing raw liquor part that it will be come out by raw liquor pump directly enters into evaporate station and evaporates by being arranged on bypass pipe behind the raw liquor pump, another part vaporizing raw liquor enters into plate type heat exchanger and carries out heat exchange with the live steam condensed water that is come out to enter into plate type heat exchanger by the stripping condensate pump, enters into evaporate station after the vaporizing raw liquor that heats up after the heat exchange and the vaporizing raw liquor in the bypass pipe are joined and evaporates; The live steam condensed water that comes out from the stripping condensate pump then enters the plate type heat exchanger along the condensate pump pipeline and carries out heat exchange with vaporizing raw liquor, is transported to steam power plant with the steam condensate (SC) of lowering the temperature after the vaporizing raw liquor heat exchange by condensate pipe and condensed water carrier pipe and carries out flash distillation.When plate type heat exchanger was rushed to repair, live steam condensed water can be delivered directly to the power plant of reducing phlegm and internal heat in the condensed water carrier pipe by water pipe (9).
