Abstract
The utility model relates to a utilization device of low-pressure industrial tail gas. A method is characterized by communicating an exhaust port of pressurized tail gas and an air pressure water pressing machine through a pipeline and arranging a pressure stabilizing device between the exhaust port of the pressurized tail gas and the air pressure water pressing machine. A recovery and utilization method of low-pressure industrial tail gas pressure energy has the effects that the air pressure water pressing machine can be driven to lift water to a higher place by utilizing the low-pressure industrial tail gas, and the air pressure water pressing machine is used for replacing an electric power water pump or storing water for electric power generation. The method has the advantages that complicated mechanical operation and more energy conversion loss are prevented due to the whole energy recovery and utilization system, the construction cost of a project is reduced, the operation is flexible, and the energy recovery and utilization efficiency is simultaneously increased; and since the pressure of exhausted tail gas can be possibly converted into lift of water by the air pressure water pressing machine, possibility is provided for ultra-low pressure exhausted industrial tail gas energy recovery.
Description
Technical field:
The utility model relates to a kind of device that can recycle the pressure of low-pressure industrial tail gas.
Background technique:
A kind of energy utilization mode with the pressure industrial tail gas is to use turbine engine, utilizes the inflation process of compressed gas, drives the turbine engine running, drives generator or pressure-increasing machine.Generally greater than the industrial tail gas emptying of 0.4MPa, its energy can reclaim by turbine engine; Industrial tail gas for less pressure often requires big flow by the condition that turbine carries out the energy recovery, is equipped with extensive expensive construction, just can reach higher utilization ratio; But for the more industrial tail gas emptying of low-pressure, such as the industrial tail gas emptying of 0.1MPa with downforce, turbine engine just is difficult to play a role.The one side inefficiency, another construction cost is too high.
Simultaneously, in modern industry was produced, dynamo-electric water pump almost was ubiquitous, and the running of dynamo-electric water pump inevitably can produce mechanical loss, and according to statistics, the average running efficiency of industrial water pump is between 40% to 60%.A large amount of electric energy in the dynamo-electric water pump loss of a large amount of round-the-clock uses.
The model utility content:
The utility model is recycled for the low-pressure industrial tail gas energy a kind of high-efficiency method flexibly is provided.Concrete grammar is, low-pressure industrial tail gas relief opening connects stable-pressure device by pipeline, and stable-pressure device is connected with the air pressure squeezer by pipeline again, utilizes the pressure of low-pressure industrial tail gas can drive the running of air pressure squeezer, the eminence of pumping up water is to substitute used electric water pump or to be used for reservoir impoundment power generation.
Described low-pressure industrial tail gas pressure can utilized device, it is characterized in that in the pump up water place of eminence of needs the air pressure squeezer being set, and connect the suction port of air pressure squeezer and the relief opening of low-pressure industrial tail gas by pipeline.
The utilized device of described low-pressure industrial tail gas pressure energy, the pipeline in the middle of connection industrial tail gas relief opening and air pressure squeezer arranges stable-pressure device.
So-called air pressure squeezer is the positive displacement structure, and principle is to utilize atmospheric pressure that the water in the squeezer volume space is realized certain lift.The air pressure squeezer does not have the complicated mechanical motion, and working pressure is low.Through test, the air pressure squeezer is arranged, even supply gas pressure is 0.01MPA, also can stablizes and realize pumping up water.
Be provided with stable-pressure device between industrial tail gas relief opening and the air pressure squeezer.Needing the interior gas pressure of pipeline to be unlikely to occur change significantly under some condition maybe needs industrial tail gas is shunted, some conditional request should prevent under special status that gas and liquid from refluxing to avoid the equipment before and after the stable-pressure device is normally moved the formation influence, and therefore the stable-pressure device that arranges here can comprise pressure buffer jar, pressure maintaining valve, atmospheric valve, safety check, part flow arrangement etc.
If industrial tail gas contains too much solid particle or liquid, purification plant should be set, industrial tail gas is fully purified, remove solid granulates or liquid in the tail gas, with the running of avoiding blocking pipeline or influencing the air pressure squeezer.
After the pressure of industrial tail gas can be recycled, should exhaust duct be set at the relief opening of air pressure squeezer, exhaust emissions is done other utilizations to the local or recovery of safety.
Utilize low-pressure industrial tail gas to drive the air pressure squeezer as a kind of mode of energy recycling, advantage is that whole energy recycling system has been avoided complicated mechanical running and more energy transition loss, reduced the cost of project construction, and running flexibly, improved the efficient that energy is recycled simultaneously.Because the air pressure squeezer can be converted to the lift of water to the pressure of discharge tail gas in the highland as far as possible, therefore provide may for the industrial tail gas energy of super-low voltage discharging reclaims.
Description of drawings:
Below in conjunction with accompanying drawing this technology is described further.
Accompanying drawing is used in a schematic representation that drives the air pressure squeezer for the low-pressure industrial tail gas recycle.
As shown in the figure: 1 is exhaust gas cleaner, 2 is stable-pressure device, and 3 is one-level air pressure squeezer, and 4 is secondary air pressure squeezer, 5 is the three stage gas pressure squeezer, 6 is admission line, and 7 is one-level air pressure squeezer intake pipe, and 8 is one-level air pressure squeezer water inlet, 9 is secondary air pressure squeezer water inlet, 10 is three stage gas pressure squeezer water inlet, and 11 is the outlet pipe that is connected in parallel, and 12 is the pond.
Embodiment:
A specific embodiment of accompanying drawing multistage air pressure squeezer running for low-pressure industrial tail gas drives.As shown in the figure, low-pressure industrial tail gas enters exhaust gas cleaner 1 by pipeline, remove solid or liquid substance, enter stable-pressure device 2 via pipeline, the low-pressure tail gas that stable-pressure device 2 is discharged enters and drives one-level air pressure squeezer 3 respectively through pipeline 6, secondary air pressure squeezer 4, three stage gas pressure squeezer 5, after water in the pond 12 enters one-level air pressure squeezer 3 via intake pipe 7, under atmospheric pressure, constantly enter secondary air pressure squeezer 4 via water inlet 8, and under atmospheric pressure, enter three stage gas pressure squeezer 5 via water inlet 9, under atmospheric pressure, discharge via water inlet 10 at last, realize last lift.After air pressure squeezers at different levels were realized pumping up water, the industrial tail gas that has utilized passed through exhaust duct 11 discharged to the external world.
