Description
Technical field
The present invention relates to a kind of plant gasfier kitchen range, relate in particular to a kind of plant gasfier kitchen range of forming by devices such as inner core courage, flue, carriage, igniter, discharge apparatus, check-valves, temperature sensor, combination valve, combustion head and automatic pollution discharge releases.
Technical background
It (is ZL 00233473.9 with the patent No. as shown in Figure 1 that the home straw cooking range capable of gasifying was come out one after another before and after 2000, ZL00342067.1, ZL 01207416.0 data such as patent document such as grade), wish to reach to make full use of the plant regeneration resource that the rural area is easy to get, improving the purpose of life of farmers environment, but owing to the problems that exist in the design of straw gasifying cooking stove do not have substantial breakthrough technically, can not form regular product and be forced to end.Its subject matter performance is as follows:
One, as complex structures and unreasonable such as leaching plate 3, collector ring 4, water leg 5, clarifiers 17, raw materials consumption and manufacture difficulty have but been increased greatly.Because of adopting the design standard of low pressure vessel, the also super 2mm of minimum wall thickness (MINI W.) that causes body of heater 6, water leg 5, clarifier 17 etc., because of being the common low carbon plate with material, its service life is also only about 5 years, high temperature deformation because of arc welding produces makes the outward appearance grade of body of heater second-rate.
Two, flue 7 usefulness refractory cements are mixed the on-the-spot manual manufacture moulding of a certain proportion of aggregate, because of the inconvenience of constructing, bring difficulty for the typing of the interior cone angle 14 of flue 7, cone angle 14 is all greater than 40 ° in the flue after the moulding, inner conical surface 13 is coarse, and is uneven, the flue 7 after the typing, weight all surpasses 120kg, causes trouble for transportation, resettlement.
Three, owing to only considered the fire resistance of flue 7 materials, ignored the important function of flue 7 material heat-insulating properties, add no effective thermal insulation layer between flue 7 and the body of heater 6 again, so body of heater 6 outside wall temperature in use can be absolutely unsafe up to more than 200 ℃.
Four, the black furnace igniting is on the fire grate of earlier a small amount of raw material being put in the stove 12, with the raw material on burning things which may cause a fire disaster (as the oily cotton yarn etc.) fire grate 12 that ignites, and the machine switch that the blows in fan switch 23 that stops after 23 a few minutes, in stove, fill it up with raw material rapidly, in these a few minutes, be that Dark smoke billows, dust flies upward, and is touching.Particularly bank up a fire in the stove extinguish after, need unburnt raw material in the stove is all drawn out, repeat the above-mentioned process of igniting again, time-consuming, effort, dirty, tired but also trouble not only not only have a strong impact on its usability, practicality.
Five, in the use, unburnt raw material can fall ash entrance chamber 10 from the spacing between the fire grate 12, cause waste.Particularly the temperature in stove internal combustion district reaches more than 1150 ℃, inorganic matter in the raw material (ash content) begins fusing and forms clinker and stay not following grey chamber 10 on the fire grate 12 in the time of 890 ℃, needing to open every day ash door 11 usefulness draws hook and draws the clinker on the fire grate 12 broken, at this moment, the a large amount of raw materials of carbonization in the reducing zone sliding ash entrance chamber 10 of can taking advantage of a situation causes bigger waste, but also the stability of influence gasification, therefore, the rate of gasification of this stove＜50%.
Six,, be easy to make raw material in stove, to form the arch bridge phenomenon of caving in because cone angle 14 is greater than 40 ° in the flue, and inner conical surface 13 is coarse again, and is uneven.The wind that enters the combustion zone because of airduct 8 be Nogata to, part airduct 8 causes combustion zone oxygen supply inequality inevitably by lime-ash or raw material block resistance, cause local burning, until the raw material layer burning hole is destroyed gasification condition, therefore, the gasification of this stove is extremely unstable, and is also difficult lasting.
Seven, beat Ji fan switch 23 with gas at every turn after, 3-8 minute time such as need just has combustion gas and produces, accurately holds CO combustion gas output and be difficult to constantly, estimate by rule of thumb entirely and declare, normal because of opening gas valve 20 in advance, cause flue gas from the combustion head 19 pollution indoor environment that comes up, sometimes need return multiple examination just has combustion gas to come out several times, very inconvenient.As the overlong time that waits, the CO combustion gas that generates can bleed off from atmospheric valve 1 again in vain, causes waste.
Eight, during blowing out, CO or flue gas in the stove can be through airducts 8, annular passage 9, outwards return out from fan wind inleting tube 16 and pollute indoor environment, the detonans that rings in addition sometimes is though be equipped with control valve 15 on the fan wind inleting tube 16, but inconvenience operates, particularly close control valve 15 too after death, anoxic in the stove is banked up a fire and is easily extinguished, raw material in the stove need be drawn out again and be ignited, this has just more bothered.
Nine, every use is 2 days, and is all will be from blowoff valve 18 discharging not only dirty but also the tar mixed waste liquor of peculiar smell arranged.
Ten, with in the gas operating process, need open electronic ignitor switch 22 earlier, open gas valve 20 again, after drive air distribution valve 21, cumbersome, particularly often open too quicklyly or out of proportion because of air distribution valve 21, cause combustion head 19 to take off fire or cutoff.
11, owing to the not enough science of combustion head 19 structural designs, add fuel gases calorific value again and be lower than 1000 kilocalories/m
3, air pressure is less than 200Pa, though so the flame on the combustion head 19 is high, unable, flame temperature is also lower, influences result of use.
When 12, opening bell 2 and add raw material, to dirty, drop on the water leg 5 when being condensate in the globule on the bell 2 and can standing upside down, stay the tar mark of pitchy after withered along bell 2, neither attractive in appearance, also unhygienic, also have peculiar smell.

2And emit a large amount of heats, improve rapidly temperature in the stove, high-temperature gas to down and on pass raw material layer, with raw material carbonization (reducing zone), thermal cracking (destructive distillation layer) and drying (drying layer), also reduce simultaneously the temperature of self, filtered the most dusts self carried secretly or impurity etc.When the reducing zone temperature reaches more than 850 ℃, CO
2A small amount of CH that the raw material that gas and reducing zone are carbonized absorbs heat reduction reaction generation CO combustible gas and follows the carbonization decomposition layer to produce
4, H
2And tar etc., confuse again water vapour that drying layer produces together from ventilation narrow slit 39 enter that expansion chamber 26 is condensed, mixed liquor after the sedimentation, condensation sedimentation flows into gas-liquid separation chamber 63 once more after the condensation separation from the outgoing gas connection tube 51 pleasant pipe 54 that comes out, flow in the fluid-tight run-offs 64 from blow-off pipe 65 and enter trench 66 automatically.
Because gas-made technology is simple, the CO in the gas, H
2, CH
4Deng combustible gas only below 25%, CO
2Content is more than 6%, and the overwhelming majority is N
2, account for more than 65%, also have a spot of water vapour and tar impurity etc. in the gas, therefore, calorific value is lower than 1000 kilocalories/m
3, air pressure is less than 200Pa.Can't reach result of use with existing liquefied gas (or coal gas) kitchen range.
Tar matter in the gas is a kind of grease of pitchy, and peculiar smell is arranged, incendivity, proportion between 1.05-1.12, the overwhelming majority filtered by raw material layer or condensation after flow in the fluid-tight run-offs 64 from blow-off pipe 65 and to enter trench 66 automatically.The tar gas of also not removing confuses combustion gas free from extraneous odour after the abundant burning of combustion head 59, also can increase certain heat, and use is not had negative effect.Not drying up or not having under the situation at dead angle, can not block pipeline yet.
