Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, a kind of plant gas heat energy utilization system, comprise oxygen-eliminating device a1, oxygen-eliminating device b2, heater 3 and drain tank 4, described oxygen-eliminating device a1, the connector of oxygen-eliminating device b2 by placed in series together, the oxygen exhaust of described oxygen-eliminating device a1 and oxygen-eliminating device b2 is equipped with an oxygen discharging door 5 and secondary oxygen discharging door 6, described heater 3 is connected with between a described oxygen discharging door 5 and secondary oxygen discharging door 6, an inlet valve 7 is provided with in the side of described heater 3, described inlet valve 7 is connected with described drain tank 4 by booster pump a8, also be connected on described drain tank 4 at the opposite side of described heater 3.
In the utility model, be provided with triple valve between an oxygen discharging door 5 on described oxygen-eliminating device a1 and oxygen-eliminating device b2, secondary oxygen discharging door 6, between two triple valves, pass through tubes connection.
In the utility model, the pipeline on the connector of described oxygen-eliminating device a1 and oxygen-eliminating device b2 is connected on described drain tank 4 by booster pump b9.
In the utility model, described booster pump a8 and booster pump b9 is equipped with several valves.
In the utility model, described valve is two inlet valves and a flowing water Valve respectively.
Oxygen-eliminating device waste heat hydraulic recovery adopts the heater 3 one of FYW-80 type injecting type mixing.Utilize existing drain tank 4, a part of water is extracted out from drain tank 4, the booster pump a8 newly installed additional is utilized to pressurize, fluidic vectoring thrust negative pressure is produced in contact(-type) heater, the steam that oxygen-eliminating device is discharged is sucked back in heater 3, makes this part exhaust steam all be condensed into condensate water with water mixed heat transfer, return drain tank 4 together with the water that drain tank is extracted out, hydrophobic in heating drain tank 4, the steam drain that the oxygen reclaimed from oxygen-eliminating device is then newly installed additional by drain tank 4 is discharged to air.
For heating the hydrophobic of drain tank 4 after the steam discharge of oxygen-eliminating device a1, oxygen-eliminating device b2 all reclaims, from 24 of drain tank 4 0the hydrophobic of about C is heated to 92 through exhaust steam heater 0c, then enter in drain tank 4 water temperature in drain tank 4 is increased to 51 0c.Like this, the water temperature of drain tank 4 is by original 24 0c is increased to 51 0c, the water temperature entirety of drain tank 4 improves 27 0c squeezes into the water of drain tank in oxygen-eliminating device and heats, and when not installing oxygen-eliminating device waste heat residual pressure recovering equipment additional, drain tank 4 enters the drain temperature of oxygen-eliminating device 24 0about C.
After oxygen-eliminating device waste heat residual pressure recovering equipment is installed, can water temperature 24 0c's is hydrophobic through contact(-type) heater, by 104 0the steam of C makes drain temperature be increased to 92 0c, then enter in drain tank through piping, to make in drain tank 4 water temp. heating to 51 0c.Because this system is continuously run, as long as the throttle (steam) temperature of contact(-type) heater remains unchanged, the drain temperature so in drain tank 4 also remains on 51 always 0c.To put into operation situation from this device, this device can meet need of production, and the waste heat overbottom pressure that oxygen-eliminating device is discharged is fully used again, hydrophobic by 24 in drain tank 0c is increased to 51 0c, entirety improves 27 0c.Both ensured the recycling of oxygen-eliminating device exhaust steam, also ensure that the separation discharge of oxygen discharged by oxygen-eliminating device.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model, the technical staff of the industry should understand, the utility model is not restricted to the described embodiments, what describe in above-described embodiment and description just illustrates principle of the present utility model, under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, these changes and improvements all fall within the scope of claimed the utility model, the claimed scope of the utility model is defined by appending claims and equivalent thereof.
