Description
Technical field
The utility model relates to the flash condenser that use in a kind of gasification field, is specially a kind of vertical flash condenser of graded gasification furnace grey water handing.
Background technology
The cleaning of coal and efficient utilization are the great technical tasks in current China energy and environment protection field, also are one of gordian techniquies of Chinese national economy sustainable development.All enterprises are all carrying out comprehensive utilization of resources energetically, energy-saving and cost-reducing, accomplish heat, electricity, vapour, cold comprehensive utilization balance, adjust dynamic structure, realize the cascade utilization of the energy, waste heat top pressure power generation, and safety and environmental issue are subjected to the attention of enterprise day by day on the other hand, starting of all items can not have the hidden danger of safety and environmental protection now, and problems such as safe spacing will just solve in total figure arrangement stage.Problem of environmental pollution often links together with security incident, and great environmental pollution accident takes place under the enterprise accident state often, so safety in production is again the important prerequisite of environment protection.Vapourizing furnace is the key equipment of gasification, is directly connected to the long-term operation of gasification installation, and flash condenser then is the visual plant of water treatment, directly influences the long-term operation of gasification installation.At present, in the technology that adopts air flow bed to gasify, with the coal water slurry is that the representative vapourizing furnace of raw material has Texaco (Texaco), its deslagging mode is liquid wet method deslagging, identical with the deslagging mode of graded gasification furnace, after groping for a long time and summarizing the experience, the operation of gasification installation has not been a subject matter, and in water treatment system, along with improving constantly of vapor pressure, the maximization of unit vapourizing furnace treatment capacity, water treatment system can not long-term operation performance more and more outstanding, become the bottleneck that influences the gasification installation long-term operation.Particular problem mainly is that the obstruction of the flash condenser of use at present is to cause Heisui River to overflow to flash condenser owing to liquid variable valve under the vacuum flasher stops up, thereby cause flash condenser to stop up, on the other hand since unit capacity generally greater than the device design flow, the insufficient space of vacuum flashing separator, partially liq just enters condenser without flash distillation, and liquid is the solid solution of high density, and deposition caking in condenser stops up condenser.Thereby cause the flash system vacuum degree control not good, worsened whole flash system.The obstruction that for this reason how to solve flash condenser has become the subject matter that influences the device long-term operation.
Summary of the invention
The utility model provides a kind of vertical flash distillation condensation separator of graded gasification furnace grey water handing in order to solve the flash condenser blocking problem that exists in the prior art.
The utility model is realized by following technical scheme, a kind of vertical flash condenser of graded gasification furnace grey water handing, comprise housing, the housing top is for having the recirculated cooling water district of circulating water intake and circulating water outlet, the housing below is for having the flashed vapour cooling zone of noncondensable gas outlet, below, flashed vapour cooling zone is a vapour liquid separator, the flashed vapour cooling zone vertically is provided with the some heat exchanging pipes that communicate with the recirculated cooling water district, on the housing of flashed vapour cooling zone, be provided with and enlarge the ring district, enlarge the ring district and be provided with the flashed vapour import, the expansion ring also is provided with the baffle relative with the flashed vapour import in the district, is provided with the spray header that has atomizer in the flashed vapour import.
60-90 ℃ of flashed vapours that come out from the vacuum flashing tank top enter the vertical flash distillation condensation separator of graded gasification furnace grey water handing described in the utility model, after the flashed vapour cooling zone heat exchange of recirculated cooling water in the vertical flash distillation condensation separator of graded gasification furnace grey water handing, flashed vapour is cooled to about 40 ℃, the refrigerative gas-liquid enters the bottom vapour liquid separator mutually and carries out gas-liquid separation, liquid phase stream enters into subsider, and non-condensable gas enters the head factory torch under the effect of vacuum pump.
The flashed vapour and the part that enter the vertical flash distillation condensation separator of graded gasification furnace grey water handing are dodged the liquid that jar is taken out of from vacuum, at first carry out flash distillation again in the expansion Huan Qu space of flashed vapour ingress, what enter that the fluid of true sudden strain of a muscle condensation separator described in the utility model at first contacts is spray water, owing to be that aqueous vapor directly contacts, so a part of flashed vapour is condensed into liquid at this, thereby reduced the enthalpy of flashed vapour, reduced the load of condenser, secondly contact is baffle, the setting of baffle has been avoided washing away of fluid heat exchanging tubulation and has been corroded, leave certain space in addition between baffle and the outer wall cylindrical shell in the bottom, thereby purpose is to avoid the high liquid of solids content to stop up import in baffle place deposition, and sedimentary solid materials is entered between the bottom the separator of bottom.
Enter the separated space of bottom once more after gas phase after the flash distillation and the water coolant heat exchange between pipe, separate cooled phlegma and non-condensable gases at this, non-condensable gases after the separation enters the head factory torch from the middle part mouth of pipe, the higher liquid of solid content enters subsider from the separator bottom, realizes the cycling and reutilization of buck after sedimentation.
Compared with prior art, the utility model 1, the plane occupation of land of having saved equipment, be convenient to on-the-spot operation: 2, the cleaning of interchanger is the problem of each manufacturer's headache, change horizontal heat exchanger into vertical heat exchanger, be convenient to the extraction of internals, alleviate the working strength that interchanger cleans greatly, also shortened the repair time.An investment cost of equipment and space have been saved simultaneously.
