Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, but not as to any restriction of the present utility model.
The utility model is constructed according to the steam collocation method in following a kind of charcoal ink factory afterheat generating system, as shown in Figure 1, the method is the high temperature and high pressure steam of exhaust heat boiler 1 outlet directly to be introduced the generator that is driven by straight condensing turbine 2 generate electricity; Then draw the steam user 4 that temperature and pressure has obtained the steam supply on-site of decaying at the non-adjustable extraction opening of straight condensing turbine.The steam that the temperature and pressure that the non-adjustable extraction opening of described straight condensing turbine is discharged has obtained decaying is regulated the steam user of rear supply on-site again by temperature-decreased pressure reducer 3.Described temperature-decreased pressure reducer adopts cooling water that the temperature and pressure of steam is regulated.If the vapor (steam) temperature of non-adjustable extraction opening and pressure are higher than user's needs, can use temperature-decreased pressure reducer to carry out desuperheat and decompression this moment.
According to steam configuration structure in of the present utility model a kind of power generation system of preceding method structure, as shown in Figure 1.Comprise exhaust heat boiler 1, straight condensing turbine 2, temperature-decreased pressure reducer 3 and steam user 4; The steam (vapor) outlet of exhaust heat boiler is connected with the steam inlet of straight condensing turbine through pipeline, the non-adjustable extraction opening of straight condensing turbine is connected with the steam inlet of temperature-decreased pressure reducer through pipeline, and the steam (vapor) outlet of temperature-decreased pressure reducer is connected with the steam user of on-site through pipeline.Described temperature-decreased pressure reducer is provided with cooling water inlet pipe and cooling water drainage water pipe; Cooling water inlet pipe is connected with water pipe.
Fig. 2 is the structural representation of prior art.In the existing afterheat generating system in charcoal ink factory, the steam that exhaust heat boiler 1 produces is normally by the steam user 4 of temperature-decreased pressure reducer 3 rear supply on-sites, and unnecessary steam enters straight condensing turbine 2 and generates electricity.
Specific implementation process of the present utility model and principle
As shown in Figure 2.The steam of prior art heat boiler outlet is to supply with first the steam user behind temperature-decreased pressure reducer, and according to the characteristics of plant area's steam load, the steam user requires generally less to the temperature and pressure of steam, because vapor (steam) temperature and the pressure of discharging from heat boiler outlet are generally higher, so need to before the steam user, temperature-decreased pressure reducer be set, the working principle of temperature-decreased pressure reducer is to adopt the lower cooling water of temperature, the temperature that enters temperature-decreased pressure reducer is lowered, in drop in temperature, vapor pressure has also obtained decay.In the process of pressure and temperature reducing, the heat energy of steam is by having lost in vain.Other steam more cooling water of the process need of pressure and temperature reducing in temperature-decreased pressure reducer, water consumption is larger, and the volume of temperature-decreased pressure reducer is also corresponding larger.
Maximum characteristics of the present utility model are that the straight condensing turbine that will drive generator directly is connected with the steam (vapor) outlet of exhaust heat boiler, utilize first the high temperature and high pressure steam of heat boiler outlet to promote the larger power of straight condensing turbine acquisition, can increase substantially generated energy, reduce energy loss.Then draw steam from the non-adjustable extraction opening of straight condensing turbine, supply with the steam user of plant area.In order to satisfy the steam user to the requirement of vapor (steam) temperature and pressure, can be according to the result of straight condensing turbine supplier to non-adjustable extraction opening medium parameter calculating, behind non-adjustable extraction opening, temperature-decreased pressure reducer is set, vapor (steam) temperature and pressure is adjusted to the scope of customer requirements.The working principle of temperature-decreased pressure reducer is to adopt the lower cooling water of temperature, and the temperature that enters temperature-decreased pressure reducer is lowered, and in drop in temperature, vapor pressure has also obtained decay.Because the steam of drawing from the non-adjustable extraction opening of straight condensing turbine is to have obtained the steam of decaying by temperature and pressure behind the straight condensing turbine, so the vapor (steam) temperature of temperature-decreased pressure reducer steam inlet and outlet is poor and pressure difference and little, so the cooling water that needs is corresponding will lack many also, but reduce water consumption, also can reduce simultaneously the volume of temperature-decreased pressure reducer, this example still adopts existing temperature-decreased pressure reducer effect meeting better.
Because each factory construction condition is different, needed steam parameter is also different, when in steam user's the parameter area of parameter (flow, temperature and pressure) at non-adjustable extraction opening, can adopt this kind configuration.Present most carbon element factory steam users' requirement has all surpassed the scope of non-adjustable extraction opening steam supply, so the utility model is only applicable to the situation that plant area's steam mean load is less and the steam load variation is little.
The utility model is in implementation process, existing exhaust heat boiler, straight condensing turbine, temperature-decreased pressure reducer have been kept, just by changing the annexation between the three, just significantly improved the utilization ratio of heat energy, reduced energy loss, save water consumption, obtained significant energy-saving effect.It is less and change little steam user that the utility model is specially adapted to plant area's steam mean load.
