Embodiment
Be noted that following detailed description all is exemplary, being intended to provides further instruction to the utility model.Unless otherwise, all technology used herein and scientific terminology have the identical meanings with the utility model person of an ordinary skill in the technical field common sense.
The chemical industry that produces speeds to exit in the process of utilizing coke-stove gas production methyl alcohol, and cleanliness is higher, and corrosive impurity is few, and has source of the gas than stable emissions pressure advantage of higher.If can seek a kind of method the venting of speeding of this chemical industry is used, not only can realize the optimization of using energy source, can realize simultaneously the maximization of interests.For this reason, inventor of the present utility model attempts the chemical industry venting of speeding is applied to power field.
As shown in Figure 1, in a kind of concrete mode of execution of the present utility model, a kind of chemical industry speed to exit system of generating that uses is provided, in this system, comprise: produce the device 1 of methyl alcohol and the electricity generating device 2 that utilizes gaseous combustion to generate electricity with coke-stove gas, produce with coke-stove gas and be provided with the chemical industry output terminal of exitting of speeding in the device 1 of methyl alcohol; And be provided with the inlet end that chemical industry speeds to exit in the electricity generating device 2.The inlet end that electricity generating device 2 speeds to exit by chemical industry and be connected with the chemical industry that coke-stove gas is produced the device 1 of the methyl alcohol output terminal of speeding to exit.
Because the calorific value that chemical industry speeds to exit is less, at 8.27MJ/M
3～9.8MJ/M
3Between, if it is directly applied to power generating equipment, can cause igniting, the raising speed difficulty of motor, speed to exit and carry out stable generating and be difficult to realize using chemical industry.The stable power field that is applied to of exitting of how chemical industry can being speeded, model utility find through repeatedly experiment, and the pressure of speeding to exit by the control chemical industry with the chemical industry air inflow of exitting of speeding, can solve the little deficiency of calorific value that chemical industry speeds to exit.
In a kind of concrete mode of execution of the present utility model, this application chemical industry is speeded to exit and is provided with the pressure regulator 3 of adjustments of gas pressure in the electricity generating device 2 in the system of generating, this pressure regulator 3 is arranged on the inside of electricity generating device 2, and the suction port of speeding to exit with the chemical industry of electricity generating device 2 links to each other.This pressure regulator 3 is a decompressor, and decompressor is regulated the pressure that chemical industry that the suction port of speeding to exit from chemical industry flows into speeds to exit, and makes the pressure after the downward modulation be lower than 2.5Mpa.
In the prior art, the electricity generating principle of the equipment that the application gaseous combustion is generated electricity is: after the gas turbine running, the gas compressor of gas turbine continuously sucks air and supercharging from ambient atmosphere, after coming out, the air after the gas compressor supercharging promptly enters the firing chamber, carry out blending at firing chamber import and the fuel that is sprayed into, ignition then, produce the combustion gas of High Temperature High Pressure, the combustion gas of High Temperature High Pressure sprays from combustor exit, just begin to expand, when expanding, promote the turbine blade acting, after turbine is kinetic energy with the Conversion of energy of combustion gas, being used for gas compressor pressurized air continues to carry out [thermodynamic on the one hand, on the one hand by the moment of torsion output of main shaft with rotor, drives generator for electricity generation in addition.
The application chemical industry that in the utility model, is provided speed the to exit system of generating, owing to used by this chemical industry of coke-stove gas production methyl alcohol institute association and speeded venting as gas raw material, the pressure that this chemical industry speeds to exit is bigger, can save the supercharging device in the pressure regulating system, reduced electricity generating device from power consumption, simultaneously, venting is purer because this chemical industry is speeded, pollute and lack, reduced corrosion, reduced the maintenance work of equipment equipment.
In a kind of concrete mode of execution of the present utility model, this application chemical industry is speeded to exit and is provided with fuel adjusting actuator 4 in the electricity generating device in the system of generating, fuel adjusting actuator is provided with the adjusting air valve, in order to regulate the gas flow area that described chemical industry speeds to exit.Preferably, regulate the gas flow area 0～2000mm of air valve
2The gas flow area of regulating air valve is made as 0～2000mm adjustablely
2, can guarantee air demand 2000～7000Nm that chemical industry speeds to exit in the electricity generating device
3/ h, and then the stable electric generation of assurance power generating equipment.
In a kind of concrete mode of execution of the present utility model, this application chemical industry is speeded to exit and is comprised pressure regulator 3, fuel adjusting actuator 4 and the generator set 5 that connects successively in the electricity generating device 2 in the system of generating, the chemical industry that regulates pressure and the gas air demand venting of speeding is passed into generator set 5, just can realizes using chemical industry speed the to exit stable application of generating.
In a kind of concrete mode of execution of model utility, this application chemical industry speeds to exit, and employed electricity generating device is a Gas Turbine Generating Units in the system of generating.QDR20 type Gas Turbine Generating Units for example.This QDR20 type Gas Turbine Generating Units can realize the performance of cogeneration.
The Gas Turbine Generating Units of failing to come into operation is all arranged, for example above-mentioned QDR20 type Gas Turbine Generating Units in most coke-oven plant.Before coke-stove gas was not used in production methyl alcohol, most coke-stove gas was transported in this QDR20 type Gas Turbine Generating Units and carries out cogeneration.Along with the progress of society, development of science and technology, coke-stove gas is applied to producing methyl alcohol gradually, and this QDR20 type Gas Turbine Generating Units is left unused, and no longer utilizes, and this QDR20 type Gas Turbine Generating Units can not get using, not only waste resource, also taken the space.The venting of in the utility model chemical industry being speeded uses this QDR20 type Gas Turbine Generating Units to carry out cogeneration, has formed a stable production chain.
The chemical industry venting of speeding is applied to power field, can improves the value that chemical industry speeds to exit, improved economic benefit, simultaneously can protect environment better, avoid environmental pollution.In addition, the speed high purity of venting own, corrosive material of chemical industry is few, uses the chemical industry venting of speeding to power as combustion gas, can prolong the working life of power generating equipment.
The above is a preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within spirit of the present utility model and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
