Description

A kind of energy-storage system

Technical field

The utility model belongs to energy-storage method field, and in particular to a kind of energy-storage system.

Background technique

Accumulation of energy mainly stores electric energy or thermal energy.

At present in accumulation of energy side: existing way of energy storage mainly has mechanical accumulated energy (such as spring energy-storage), heat accumulation accumulation of energy, chemistry Accumulation of energy, water-storage etc., in addition to water-storage, there is the deficiency of " accumulation of energy energy is smaller, and accumulation of energy is limited " in other way of energy storage. At the same time, in existing way of energy storage, all only simple accumulation of energys, the production of not new value during the savings of energy It is raw.

In energy resource supply side: being that a large amount of light and heat energy are wasted first；Followed by, there are a large amount of abandonments, abandoning for new energy field Light, the situation for abandoning water (are limited to that generation of electricity by new energy itself fluctuation is larger, there are the unstable factors such as randomness, intermittence, meeting The reason of causing a hidden trouble to the safe operation of power grid, therefore yield wind energy, luminous energy and water energy, stop corresponding generating set or subtract Its few generated energy), the following contents is downloaded from " abandonment abandons light, abandons water: new energy " three abandon " is just continuous worsening ":

It is shown according to the statistical data of General Acadamy of Power Planning and Design, national abandonment electricity increased from 33,900,000,000 kilowatt hours in 2015 49,700,000,000 kilowatt hours in 2016 are added to, abandonment rate rises to about 17%.

The Northwest is sunny, is the important area of China's photovoltaic power generation in recent years.But investigation discovery 2016, is abandoned Light also occurs mainly in the Northwest, and abandoning optical quantum is increased to 7,000,000,000 kilowatt hours in 2016 by 4,900,000,000 kilowatt hours in 2015, It abandons light rate and improves 6 percentage points.

The investigation of General Acadamy of Power Planning and Design is found, 2016, is abandoned water and is occurred mainly in Sichuan, two province of Yunnan.And this two A province is the more flourishing region of China's water power, and data shows that the total reservoir storage of Drainage Area of Jinsha River planning is up to run-off 83%, Yangtze upriver areas total reservoir storage is up to the 61% of stream runoff, is more than that internationally recognized 40% water resource is opened Send out producing level warning line.Sichuan Province's whole year in 2016 is more than the increased digestion capability of system due to increasing hydropower installed capacity newly, And without newly-increased ability to send outside, abandoning energy is further increased, and about 14,200,000,000 kilowatt hours increase by about 39% on a year-on-year basis, creates nearly 5 years newly It is high.

In addition, there is also following shortcomings for the existing energy-storage method for abandonment or abandoning light:

For example, in the prior art the patent of notification number CN105371343B disclose it is " a kind of to abandon light heat supply using abandonment Boilers heated electrically storage heating system and its application method ", the technical solution can abandon light using abandonment to power to high pressure electric boiler Heat water, after heating water met into district heating demand as personnel.But the technical solution is that abandonment is abandoned to the energy of light Amount, is converted into thermal energy by high pressure electric boiler immediately, is immediately available for huge numbers of families' Home Heating and consumes after the energy heats water Expense falls the energy that light is abandoned in abandonment.So the technical solution can not carry out large-scale storage, also, heat for a long time to electricity is abandoned Energy transmit process loss is larger, therefore thermal energy is also difficult to realize Long Distant Transmit.

In addition, the document of notification number CN108039713A discloses " a kind of abandonment and extensive electric heat accumulation in the prior art With battery energy storage coordinated operation method ", but the energy of abandonment is converted into thermal energy or storage in the battery by the technical solution, is existed It is complicated for operation, stored energy capacitance is low, the shortcoming of battery easy attenuation loss at high cost.

To sum up, how to abandonment, abandon light, abandon water and using the relatively low nuclear power unit of hourage generated energy into The large-scale effective use of row, is always the technical problem that this field could not solve for a long time.

Based on the above background, how to provide one kind to be easily achieved, be capable of the energy-storage system of industrialized scale accumulation of energy, be urgently It need to consider the technical issues of solving.

Summary of the invention

In view of the above shortcomings of the prior art, the technical problem to be solved by the utility model is to how to provide a kind of easy In realization, it is capable of the energy-storage system of industrialized scale accumulation of energy.

In order to solve the above-mentioned technical problem, the utility model uses the following technical solution:

A kind of energy-storage system, it is characterised in that: including pulverized coal preparation system and agitating heater；

The pulverized coal preparation system includes milling equipment, and the milling equipment is used to raw coal being processed into coal dust；

The agitating heater includes tank body, and the tank body top has feeding port, and the lower part of the tank body is equipped with band There is the discharge port of switch；The tank body is internally provided with rotatable agitating shaft, and stirring is fixedly connected on the agitating shaft With blade, the outside of the tank body is fixedly installed with the driving motor for driving the agitating shaft；The tank body be equipped with for pair The heating structure of tank interior heating.

Compared with the existing technology compared with the utility model energy-storage system has the advantage, that

1, there is the utility model energy-storage system easy to implement, safe and environment-friendly, accumulation of energy time length, accumulation of energy to be reliable, easy to make With with use more flexible advantage.

Because the surface area of coal dust is big, it is in contact with the oxygen in air and is easy to cause spontaneous combustion and explosion；So existing In technology, coal dust is sent in Industrial Boiler rapidly by air blast or negative pressure equipment immediately after wearing into coal dust by flour mill Burning use is fallen.

Hydrophobic type coal dust very can be readily made using the energy-storage system of the utility model, hydrophobic type coal dust passes through it The hydrophobic material on surface to enable itself waterproof and to be opened with air insulated, so as to realize the long-time of safety and nondestructive consumption (as unit of year) storage, and it is also more safe and environment-friendly during transportation.Hydrophobic type coal dust cannot be only used for in thermal power plant Industrial Boiler use generate electricity, can also be easy to be used in Industrial Stoves to be also easy to make using coal dust to process the products such as porcelain Obtain coal gas；Therefore has the advantages that easy to use and use more flexible.

At the same time, hydrophobic type coal dust is in burning, and real-time manufacturing on the spot, being used while making, and when non-hydrophobic type is handled Coal dust property it is the same.It is same to have burning rapid.Therefore very little is lost in accumulation of energy, energy storage effect is excellent.

2, it is easy to the generated electricity for making full use of abandonment, abandoning light, abandoning water and the nuclear power unit for utilizing hourage relatively low Can, and realize the accumulation of energy of industrialization and scale.

Firstly, powder manufacturing apparatus is existing equipment, it is easy to largely purchase and install and use, and the number of units of powder manufacturing apparatus can be passed through Instantaneously to adapt to wind energy, photovoltaic power generation or hydroelectric intermittent feature and power grid trough-electricity not with variable (electricity consumption) power The input (thering are more electric energy just more to open powder manufacturing apparatus, less electric energy just opens powder manufacturing apparatus less) of timing, namely have wind, light Water etc. produces electricl energy just powder processed, the energy such as calm, unglazed, anhydrous just powder not processed.Wind is big (light intensity), just more systems.Wind is small (light is weak) Just few system.And so on.

By upper, the energy-storage system of this programme can adequately absorb abandonment, abandon light, abandon water and utilize hourage relatively low The generated energy of nuclear power unit overcomes the utilization problem of " abandonment abandons light and abandons water " of long-standing problem this field.

3, remarkable in economical benefits.

Firstly, because coal dust can be improved efficiency of fire coal compared to having bigger surface area for coal cinder, fever is improved Amount.Therefore the coal dust of Unit Weight can discharge more thermal energy compared to the coal cinder of equivalent weight, that is, the energy storage density of coal dust It is higher with energy releasing efficiency.

Then, because China western part (for example, Xinjiang) and the Northwest (for example, Gansu or Inner Mongol) coal storage resource is rich Richness, most of coal storage it is resourceful be also photoelectricity, wind-powered electricity generation production capacity aggregation area (for example, Hami city and Xinjiang Tuoli County).

Such as: Xinjiang thermal coal is from Xinjiang various regions through transporting for long-distance to user, and will consuming station service, (can surf the Internet electricity Amount) come powder processed, usually to high-efficient thermal power plant, coal dust, which is made, in one ton of coal needs 20 kilowatt hour of power consumption or more.Therefore, if by coal Just consumption low-quality energy (for abandonment, abandons light, abandoning water and using caused by the relatively low nuclear power unit of hourage before shipping Energy) be made into coal dust, coal dust per ton in this way compared with raw coal with regard to more accumulation of energys at least 20 kilowatt hours more than.If by 1,000 ten thousand tons Coal dust, which is made, just in coal needs 200,000,000 kilowatt hour of power consumption.It is equivalent to 7000 hours full generated energy of one 30,000 (kW) unit.

Currently, 1.6 hundred million tons of the every annual output steam coal in Xinjiang, is all that can surf the Internet after coal dust is made in electricity to make in user terminal consumption With.Need to consume every year can be more than 3,200,000,000 kilowatt hour of electricity volume.

Meanwhile 132.5 hundred million kilowatt hour of Xinjiang whole year abandonment electricity in 2017,28.2 hundred million kilowatt hour of optical quantum is abandoned, is added up to 160.7 hundred million kilowatt hours are able to satisfy the powder electricity consumption processed of 800,000,000 tons of coals.Therefore after the energy-storage system of use the utility model, it can incite somebody to action The abandonment electricity and abandoning optical quantum of Xinjiang region make full use of, and the portion of energy is saved in the form of hydrophobic type coal dust Come.

Therefore using the energy-storage system of the utility model after, be easy to each generation of electricity by new energy field, producing coal (benefit Electricity or trough-electricity are abandoned with new energy) or coal distribution centre (abandoning electricity or trough-electricity using new energy) implementation, and make full use of The energy that good new energy generates avoids huge waste caused by shutting down；At the same time, hydrophobic type coal dust obtained is used for thermoelectricity After factory or Industrial Boiler, additionally it is possible to reduce thermal power plant or Industrial Boiler and directly be prepared using " general industry peak of power consumption electricity price " Coal dust, so that the use unit of thermal power plant or Industrial Boiler is helped to reduce expenses, Improve Efficiency.As it can be seen that the storage of the utility model Energy system can generate significant overall economic efficiency.

Note: by taking photovoltaic power generation as an example, in recent years, inefficient product is quickly eliminated by market, and high efficiency products not only become main Stream, price also constantly decline.Nowadays, such as in India, the price of photovoltaic power generation is that 0.04 dollar of every kilowatt hour (is converted by 1 dollar 6.7 yuans of the exchange rate is changed to calculate, then is 0.27 yuan of every kilowatt hour of RMB), it is also lower than the price of thermoelectricity.

Currently, China equally carries out " time-of-use tariffs " with many countries in the world.By taking Jiangsu as an example, general industry is used Electric peak electricity tariff is about every 1.4 yuan or so of degree, and low ebb electricity price is about 0.4 yuan or so;And external electricity price price differential easily 5 times with On.After German new energy participation is bidded, due to there is government subsidy, when wind-powered electricity generation is more, negative electricity valence is usually quoted.

To sum up, after using the energy-storage system of the utility model, economic benefit will be more significant.

4, it helps to realize a kind of more preferably power supply mode.

After the energy-storage system of the utility model, abandons electricity or trough-electricity by current and process obtained hydrophobic moulded coal Powder (and the cost of hydrophobic type coal dust is also lower)；Then, in electricity peak period, thermal power plant can largely using hydrophobic type coal dust come Power generation is to meet on-peak demand.In this way the energy of electricity or trough-electricity can will be abandoned by the energy-storage system of the utility model Amount savings in the form of hydrophobic type coal dust are got up, and are used for peak times of power consumption " filling out peak ", so as to help so that entire power grid It is more steady reliable, and obtain more preferably comprehensive utilization rate of energy source.

5, accumulation of energy that can be more flexible is realized " with can be without timeliness ".

" with can be without timeliness " refers to energy consumption system consumption electric energy and to generate work achievement unrelated with the time that electric energy inputs. As long as there is electric energy input whenever and wherever possible, work achievement is generated.Instantaneous inputing power is more, the work achievement instantaneously generated Directly proportional increase.

Currently, after coal dust is made in global coal, in transit due to coal dust, after contacting with the air, with fugitive dust, certainly Combustion, explosive, volatile matter are easily precipitated compared with lump coal transports, since the effect of the moisture absorption and oxidation leads to the factors such as calorific value decline, So that coal dust can neither conventional storage, can not routinely transport safely over long distances.Therefore coal can only be transported to each dispersion After user, coal dust just is made in coal and must use that (coal dust category second level combustible and explosive articles, must not contact with air immediately In the case where mass storage).This makes the cost of powder electricity consumption processed be exactly the electricity price of user locality or the rate for incorporation into the power network of user's power generation. Although coal centralized system is met to the requirement " with can be without timeliness " at coal dust, but since the characteristic that coal dust is difficult to store and transport makes The advantage for obtaining this " with can be without timeliness " cannot be embodied in economic benefit.

The coal dust of what coal (including lignite) nothing during long term storage and long-distance transport can be made using the utility model The loss of any weight and quality, the generation for the problems such as preventing spontaneous combustion, fugitive dust, the moisture absorption completely；So hydrophobicity coal dust can be with close It closes vehicle storage and pneumatic equipment is loaded and unloaded.In this way in the pulverizing process of coal before shipping, so that it may be set using adjusting powder The quantity of coal pulverizer operation in standby and power meet the needs of wind-powered electricity generation, the randomness of photovoltaic or water power power generation, fluctuation, energy The variation for effectively adjusting network voltage, frequency and phase caused by generation of electricity by new energy keeps large-scale wind power and photovoltaic power generation convenient It is incorporated to normal grid reliably for " centralized system carrys out storage energy in the form of hydrophobic type coal dust for hydrophobic type coal dust ".Cause This, is made hydrophobic type coal dust for raw coal concentration, is the requirement met " with can be without timeliness ".

6, hydrophobic type coal dust is easy to convey using aqueduct, more significantly reduces use cost.

Exactly because hydrophobic type coal dust can waterproof, therefore can directly be conveyed by aqueduct, accordingly even when it is defeated Cost is sent substantially to be lower than iron tyre transportation cost and automotive cost, acquisition is significantly more to use advantage；Also as aqueduct It builds difficulty and construction cost is lower, therefore can directly laying water pipes be used with coal dust with manufacturing to connect hydrophobic type coal dust Region or single user, so that using for hydrophobic type coal dust is more convenient.

7, it transports and storage loss is low, economic benefit is more excellent.

State Bureau of Building Materials Industry provides: the quota proportion of goods damageds of large raw material are respectively as follows: coal≤4%, grain slag≤5%, iron powder (sulfate slag)≤3%, gypsum≤3%.Coal can be lost with the wind due to wind-force etc. in storage, transportational process, shed and raise Dirt.According to statistics, at present in the transportational processes such as railway, highway, primary to transport coal loss about 0.8% -1%, transport (transhipment) is secondary Number is more, is lost bigger.

Coal stores calorific value in 1 year in air can reduce ratio about are as follows: 8 to 30%.Wherein, smokeless calorific value of coal reduce compared with Few, lignite calorific value reduces highest.

By upper, existing coal has detraction using automotive or railway transportation (breakage is brushed or leaked and spills)；And coal is aerobic Meeting exothermic oxidation is stored in environment and reduces calorific value (so that heat reduction of final burning release).

The hydrophobic type coal dust accumulation of energy produced using the utility model energy-storage system, (such as: packaging using closed vehicle Case, or the tank body with closed charging door and/or closed material taking mouth) hydrophobic type coal dust is loaded, consequently facilitating automotive Or railway transportation, and fugitive dust and leakage is avoided to spill loss, it is effectively reduced or avoid transport to be lost, and the feature of environmental protection of Lifting Convey.

In addition, the hydrophobic type coal dust accumulation of energy produced using the utility model energy-storage system, it is defeated to can also be used hydraulic pipe It send, for automotive or railway transportation, and further can substantially convey cost, promote economic benefit.
