Abstract
The utility model relates to an air cooling heat-pipe vapor generator for the continuous oxygen-enriched content air production, designing a heat-pipe vapor generator which adopts a heat pipe as a heat transferring element, isolates the air and the vapor (water), can effectively regulate and control the temperature of a pipe wall, avoids the phenomenon of dew point corrosion, generates the vapor of the 2.5 MPa, and satisfies the vapor used by the postorder production technology. The heat-pipe vapor generator comprises riser pipes, downcomer pipes, and vapor domes. The utility model is characterized in that a plurality of heat-pipe vapor generators are adopts the arrangements of connection in series. Heat pipes in the heat-pipe vapor generator are arranged in inclination. A plurality of vapor domes composed of cooling sections of each heat pipe which are inserted into corresponding pipe sleeves are connected by numbers of riser pipes and downcomer pipes.
Description
It is various heat exchange and the waste-heat recovery device that heat transfer element is formed that the utility model belongs to the heat pipe, is but heat pipe evaporator of a kind of continuous oxygen enrichment gas-making process air cooling specifically.
At present, each middle scale nitrogenous fertilizer plant gas-making process is a raw material with coal, coke all, in gas generator, adding water vapour with oxygen-enriched air is gasifying agent, produce 1000 ℃～700 ℃ high temperature semiwater gas (title process gas) continuously, through the useless pot of gas making the process gas temperature is reduced to below 250 ℃, through the unstripped gas of post-order process as production nitrogenous fertilizer.The general tubular heat exchanger that adopts of the useless pot of the gas making here, technology is made tube side leave with rage, and vapour, water are walked shell side and are carried out heat exchange, and the process gas temperature is reduced, and are cooled to temperature requiredly, produce the following low-pressure steam of 0.3MPa simultaneously.Because dustiness is higher in the process gas, dust constantly washes away, and the dew point corrosion of heat exchanger tube self and pipe breakage, causes a large amount of water, vapour to leak, and enters semiwater gas technology flue, has a strong impact on and produces and security.Produced simultaneously steam pressure is low excessively, can't satisfy process steam in the post-order process.
The purpose of this utility model then is the problem at above-mentioned existence, having designed a kind of employing heat pipe is heat transfer element, gas---vapour (water) is isolated, can regulate effectively and the control valve wall temperature, avoid the dew point corrosion phenomenon, and produce the steam of 2.5MPa, satisfy the heat pipe evaporator of postorder production technology with vapour.
The utility model technical solution:
A kind of continuous oxygen enrichment gas-making process air cooling of being made up of tedge, down-comer, drum is heat pipe evaporator but, it is characterized in that some heat pipe evaporators adopt arranged in series, heat pipe in the heat pipe evaporator is obliquely installed, and cold section of each root heat pipe all inserts to be formed some and link to each other with drum by several tedges, down-comer in the corresponding sleeve pipe; Sleeve pipe in each sheet is interworking architecture.
Advantage of the present utility model is as follows:
1. adopt heat pipe as heat transfer element, cold section of heat pipe is in sleeve pipe, and this part produces steam, and being heated and circulating fully and the process gas isolation of whole boiler circuit independently is present in beyond the process gas flue, is a kind of indirect type diabatic process.This just makes native system be different from the dividing wall type diabatic process of the general gas making waste heat boiler of present use.
2. separate between heat-pipe elements in the system, process gas and steam generation separate from, be independent of each other, even single or several heat pipe damages, do not influence the normal operation of system yet, water, gas can not enter process gas owing to heat pipe is damaged yet, cause the accident.
3. by the adjustment of opposite heat tube heat transfer area, the control valve wall temperature avoids occurring dew point corrosion effectively easily.
4. adopt this device can solve in the past useless pot, or dust such as wash away at the heat exchanger tube that reason is damaged because the tube sheet solder joint that thermal (temperature difference) stress causes damages.
5. simple to operate, easy to maintenance, reliable operation, the heat delivery process of whole system is without any need for exterior power.
Continuous oxygen enrichment gas-making process air cooling but heat pipe evaporator has solved a series of problems that the useless pot of gas making in the past exists effectively, and it is temperature required that process gas is reduced to, and the heat of recovery can produce process steam again, guaranteed the continuity of producing, it is simple in structure, and is stable, safe and reliable.
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 side view.
Below in conjunction with accompanying drawing the utility model is further described:
The utility model adopts U type arranged in series by four heat pipe evaporators 2,3,5,6 successively, and it is temperature required that the process gas temperature is reduced to step by step.Heat transfer element in the equipment is a heat pipe 9, and heat pipe 9 has the very big capacity of heat transmission.It transmits heat by the mobile and phase transformation of working solution in the pipe, absorb latent heat of vaporization evaporation and become steam at heat pipe 9 evaporator section working solutions, steam is flowed to condensation segment by evaporator section under certain pressure reduction, spreads out of heat, and working solution is got back to evaporator section under gravity or capillary force effect.This course of work moves in circles and carries out, so heat also continuously is transferred to condensation segment from evaporator section, promptly is transferred to low-temperature receiver from thermal source.Because transmission is the latent heat of vaporization, so heat pipe 9 can transmit more heat under the minimum temperature difference.
Heat pipe evaporator section adopts ratio-frequency welding finned tube augmentation of heat transfer in the utility model, and the heat of high-temperature technology gas is passed to the heat pipe evaporator section outer wall, and heat pipe outer wall is passed to the inside heat pipe working solution by heat conduction with heat.Absorb heat of vaporization and become steam at the evaporator section working solution, under certain pressure reduction, flow to condensation segment.Condense into liquid at condensation segment steam, emit the latent heat of vaporization, heat is passed to saturation water in the sleeve pipe 8 by thermotube wall.Saturation water absorbs heat and produces saturated vapor, is transferred to drum 12 by tedge 10, and carbonated drink is separated in drum 12, produces process steam, and drum mouth 12 saturation waters are then got back in the sleeve pipe 8 by down-comer 11.So continuously by absorb, that evaporation, transmission heat are reduced to work with the process gas temperature is temperature required, produces process steam.
