Description

Full intelligence exempts from the straw biomass miniature boiler kept an eye on and method

Technical field:

The present invention relates to the straw biomass miniature boilers that boiler technology field more particularly to a kind of full intelligence exempt to keep an eye on.

Background technique:

The thermal power of boiler is referred to as miniature boiler in 100KW D grades of boiler below, by the living space of average each household 120M2 It calculates, the miniature boiler of residents is suitble to should be 10KW or so.

Biomass granule fuel point has a two major classes by class, one kind be process using timber, sawdust, branch it is wooden Biomass granule fuel, abbreviation Wood pellets, Wood pellets calorific values is high, ash is low, burning noncoking, do not emit it is black Cigarette is the preferred fuels of the current small-sized residents biomass boiler of the overwhelming majority, but resource is limited, is not suitable for large-scale promotion； Another kind of is the straw biomass granular fuel being process using agricultural waste material, abbreviation stalk granular fuel, stalk Grain fuel value is unstable, ash is high, burning when easy coking, easy over-emitting black exhaust, but resource is extremely abundant, is suitble to large-scale promotion, But there is presently no the small-sized residents boilers of reliable performance.

In China, straw biomass enormous amount based on agricultural waste material generates nearly 900,000,000 tons, and this every year A little biomass distributions are wide, distribution dissipates, collect and transport difficult, if not being used, not only waste of resource but also to environment band Carry out huge pressure, and being warmed oneself nearby using stalk particle is also one of some effective for solving this problem；In recent years, have very For more boilers due to the operational mode for adding special messenger to keep an eye on using semiautomatic control, development is good, but these boilers be not appropriate for it is vast Rural area and combination area of city and country's dispersion occupy the use at family, and the mechanism that more families share a set of heating system is also immature, and small-sized household is used Type stalk particle heating boiler cannot also be applied, example well so far since there is also the technical problems not solved very much Such as: limited by Thermal Power Engineering system, Jilin University, the emulation of Jilin University's automobile and control National Key Laboratory, Harbin Boiler Plant Big " the small-sized biomass particle boiler combustion for waiting four people to deliver jointly in " power-saving technology " the 2nd phase in 2018 of vibration is rectified by responsible company Room design studies " it is write in paper in this way: " studied and found by a large number of experiments: there are tar for small-sized (10kw) biomass boiler Pollution, incomplete combustion, unstable and fuel lime-ash coking problem ... miniature boiler are not provided with fireman, and no special messenger sees Pipe, cannot find in time coking and handle in time, very big on the influence of the combustion conditions of bogey even if cleaning, or even can interrupt Burning "；It is straw biomass it can be seen that small-sized residents straw particle boiler technology is caused to be difficult to the true cause broken through Fuel uniqueness and small-sized biomass boiler be difficult to both controllings superposition factor caused by, integrate be primarily present with Lower problem:

2. dust pollution problem: since domestic boiler volume is unfit to do too much, inconvenience design high effect dust cleaner, slag bucket Artificial deashing is still needed to flue, black smoke fugitive dust is excessive, and effect on environment is big.

3. small boiler feed problems: by for 10kw boiler, the charging of average minute clock is only 40g or so, thermal capacity of burning It is low, feed needs are harsh, the slightly more flames that can dinch of charging, charging is slightly few and can stop working because of fracture, and it is flame-out after nothing from principal point Fire and voluntarily Restoration Mechanism.

4. continuity run problem: since the ingredient of biomass fuel is unstable, needing that boiler is arranged based on experience value Operating parameter, such as delay feed and are delayed deslagging to reach a temporary steady state condition, when fuel ash or calorific value or load are sent out After changing, grope new empirical value again to be arranged, otherwise can be detached from steady state condition, leads to furnace fuel or accumulation or row It is empty and interrupt.

5. intellectually and automatically problem: industry still focus on structure simply and low manufacturing cost, and ignore manipulation relax Adaptive, simplicity and intelligence, although some boilers also use simple program-controlled control, artificial operation difficulty and workload More than several times still bigger than hand coal-fired stove, the automation that people is freed from dust and cumbersome work situation is still not achieved Degree.

Based on the above points, seriously having constrained family's selection and using small-sized residents straw biomass Boiler heating Enthusiasm, current boiler product are also only limitted to burning Wooden Biomass fuel, and the utilization and exploitation of stalk still also lack this The domestic consumer group of one enormous amount.

11. a kind of exempt from the straw biomass miniature boiler slag position kept an eye on detection using full intelligence described in one of claim 1 ~ 8 With control method, it is characterized in that: in the preferable situation of the burner hearth (15) airtightness, by exhaust blower in certain revolving speed or one Under the conditions of determining exhaust air rate, intake is caused by clinker covering amount using the ventilation hole (60) of basket formula burning bucket (16) Variation and then the variable quantity caused stress to burner hearth calculate the height of burner hearth clinker position, further according to the result calculated to row The method of slag speed progress closed-loop control；This method comprises the following steps: determining normal slag position and the adjustable wind pressure first The movement critical point of (21) is switched, the specifically slag position by basket formula burning bucket (16) is adjusted to good position of burning, usually At 2/3, keep basket formula burning bucket (16) slag position ventilation hole as described below (60) covered, slag position the above are effective through-hole, The revolving speed of the frequency control exhaust blower (26) is transferred to a specific revolving speed, the revolving speed under usually 50Hz, then gradually by High negative pressure value adjusts the adjustable pneumatic to lower negative pressure value and compresses switch the knob of (21), until the normal opened contact of switch is just connected Until, the slag position of negative pressure value and the basket formula burning bucket (16) has determined corresponding pass by the state of blast switch in burner hearth at this time System；Secondly, thering is the slag position for being timed execution to detect sub- journey in the intelligent controller program when boiler operates normally Sequence reads the adjustable pneumatic and compresses switch the switch shape of (21) after the revolving speed that is adjusted to exhaust blower under 50Hz when the program executes State, when the slag position of basket formula burning bucket (16) is lower than 2/3, effective via count increases, and the air quantity into burner hearth increases, One timing of exhaust air rate, combustion chamber draft are worth low, wind pressure normal opened contact access failure, and the switch state being read into is 0, control journey at this time Sequence stops or reduces the working time for stirring slag motor, reduces the quantity of slag for stirring slag impeller (55) discharge；Conversely, working as the basket When the slag position of formula burning bucket (16) is higher than 2/3, effective via count is reduced, and the air quantity into burner hearth is reduced, certain in exhaust air rate When, combustion chamber draft value is high, and wind pressure normal opened contact is connected, and the switch state being read into is 1, controls program starting at this time or increases The working time for stirring slag motor increases the quantity of slag for stirring slag impeller (55) discharge, no matter fuel parameter or load variations, Long-term, stable holding best combustion slag position in furnace can all be made by above method；If reading signal is normally closed contact, described Intelligent controller programmed logic negates.

12. the inspection that full intelligence according to claim 11 exempts from slag position in the furnace of the dustless miniature boiler of the straw biomass kept an eye on Survey and control method, it is characterised in that: can also be compressed switch (21) by the way that two sets of adjustable pneumatics are arranged, and adjusted into respectively High slag position and the state point of low slag position two control the intelligent controller program between two points come the row of raising boiler slag position The accuracy of slag and the stationarity of burning.
