Description
Technical field
The present invention relates to the preparation of mah-jong mat, concretely relate to carbonizing treatment method and the device of a kind of mah-jong mat bamboo chip.
Background technology
Bamboo mat is one of mankind's daily necessities in summer, has the mah-jong mat of a kind of little bamboo chip Series Code to be similar to mahjong on the market, it is adaptable to the irregular surface such as sofa, Simmons bed.The making of mah-jong mat be by bamboo be machined to form mahjong block size little bamboo chip, after the operations such as punching, frosted, polishing, use and have resilient dowel as warp-wise connector, use high-strength nylon fine rule to do broadwise and link, little for polylith bamboo chip is arranged in order Series Code and becomes required size.
The main component of the cell wall of bamboo wood is mainly made up of cellulose, lignin and hemicellulose, three's total amount is more than 90%, separately have about 10% oils and fats, tannin, pigment, pectin, protein, starch, sugar, the electrodeposition substance such as inorganic matter in cell wall, but these materials are primarily present in lumen.Nutrient substance that bamboo wood is abundant and the special arrangement mode of bamboo culm cause bamboo wood encroached on by bacterium worm.As occurred going mouldy, damage by worms, the most then reduce product quality, affect attractive in appearance, heavy then lose use value completely.Therefore, mah-jong mat must carry out mildew-resistant, insect-prevention treatment to bamboo chip when producing.And due to the bamboo supplied materials difference used, with the bamboo point of a collection of bamboo and bamboo root, cortex and nexine, on the sunny side and in the shade quality color and luster is the most different, the mah-jong mat bamboo chip surface chromatic aberration processed is the most clearly, need to select, by color classification, labor intensity is big, and cost is high, whole dishes served at a feast uneven color of the mah-jong mat made.Therefore, in order to improve speed of production, the mah-jong mat that on market, color is highly uniform is dyed forming mostly.And mildew-resistant in the past, insect protected and colouring processing method use the mode adding the multiple chemical drugs steaming and decoctings such as dry powder, Caustic soda, the double sodium of burnt phosphorus, hydrogen peroxide, Natamycin essence, color essence in water to carry out, the unprocessed any discharge of steaming and decocting liquid medicine, causes serious environmental pollution.And the bamboo chip moisture content that obtains is higher, it is impossible to be directly used in next process, so also needing to be dried after often processing, time-consuming.Bamboo chip after process is usually in grainfield dry in the sun, and both having taken grainfield cannot cultivate, again because of the liquid medicine infiltration grainfield of bamboo chip stagnant band during dry in the sun, serious infringement arable land quality.The bed-mat for summer chemical residue medicament that bamboo chip is made, makes people catch various skin and respiratory tract disease, health is brought harm.
Current then processing method is improved to the high hot carbonization of high temperature and processes: one be high temperature high heat can make in bamboo chip rich in nutrient substance decomposes fall, make bamboo chip be not susceptible to damage by worms, go mouldy；Two are as heating-up temperature increases, extending heating time, and bamboo chip color occurs that, by the change of shallow coffee to deep coffee color, alternative bamboo chip dyeing processes.Bamboo chip is put into high temperature carbonization in retort, and bamboo chip surface can form harder carbonization particulate layer, and carbonization microgranule can form antibacterial and be difficult to living environment, thus reach antibacterial action.This mode had both solved steaming and decocting liquid medicine exhaust emission environmental problem, also solves in liquid medicine is detained bamboo chip and affects consumer health's problem.
But the dowel of mah-jong mat the most on the market is owing to being the plastic material used, after using a period of time, particularly it is placed under burning sun in similar summer in parked car etc. in hot environment, there will be catabiosis, dowel can turn to be yellow bellding, pollute sofa, sheet etc., even rupture, cause using.Because of and have producer to develop not to use the mah-jong mat of litzendraht wire tendon Bovis seu Bubali line, such as Application No. 201510446267.8, filing date 2015.07.28, the mah-jong mat mentioned in the application of invention entitled summer sleeping bamboo mat production method.The mode of production of this mah-jong mat is to be affixed directly in base fabric by bamboo chip, eliminates the operations such as the boring of bamboo chip processing, artificial braiding, thus significantly reduces the weight and volume of mah-jong mat, it is simple to transports, folds, carries and collect；Meanwhile, employing PUR or polyurethane adhesive or other bonding bamboo chip of environment-friendlyadhesive adhesive kind, environmental protection, with low cost, line production can be realized and produce, be greatly improved production efficiency.Owing to the bamboo chip of this mah-jong mat need not be holed threading, therefore can change the thickness of bamboo chip, the thickness of bamboo chip reduces, and substantially increases raw-material utilization rate.But, owing to self containing certain tissue moisture before the non-carbonization of bamboo chip, and bamboo wood itself is without transverse fiber, bamboo chip is when carrying out carbonization, once heat up too fast, relatively thin bamboo chip becomes under the influence with the rapid evaporation of contained humidity in the contracting of its organizational structure, and easily shape becomes concave-convex and even ftractures, and then makes defective products rate high.Therefore the bamboo chip that thickness is less is with greater need for the carbonization device that can slowly heat up and be heated evenly.The most relatively thin bamboo chip needs to shorten carbonization time.
And existing carbonization device cannot meet the carbonization operation of bamboo chip of this mah-jong mat.Such as, utility model patent " dried disinfecting equipment " (patent No.: 201020657859.7), invent a kind of employing Bamboo leftover as body of heater fuel, bamboo chip is put in body of heater, and limit is heated, and limit rotates, bamboo chip reaches sterilizing, the purpose of carbonization colouring by high temperature.The defect of this heating means is: owing to this retort burner hearth fuel is bamboo surplus material of processing, and during heating, temperature is too high and heating rate, cannot operate production summer at all；And the quality of bamboo surplus material of processing fuel is different, the artificial amount adding fuel and speed are the most different, so the heat produced is different.Making its heat time heating time, heating-up temperature, tapping temperature, mode of coming out of the stove (temperature is high, chance of coming out of the stove oxygen combustion) the most bad control, defective products rate is high.
The employing electrical heating also having, but need the electricity charge about 400 yuan after a stove bamboo chip processing, heating cost is high, and relative difficulty bears in the small profits manufacturing and processing enterprise of this bamboo processing.Such as a kind of material carbonizing plant, patent No. CN204819849U (publication number), improves " dried disinfecting equipment ", changes body of heater fuel into natural gas or liquefied gas, separately add Water-fog dusting apparatus, though the labor condition of improving, improve work efficiency, but processing cost is the highest, work place temperature is high, summer operation condition is poor, and owing to natural gas may occur carbon monoxide poisoning event because of imperfect combustion, safety coefficient is the highest.
Biomass fuel: referring to burn as fuel biological material, the most mainly agriculture and forestry organic waste material (such as straw, sawdust, bagasse, rice chaff, bamboo wood industrial wood waste etc.), the main distinction is in Fossil fuel.In current national policy and environmental protection standard, direct biomass burning belongs to high pollution fuel, only uses in the brick kitchen range in rural area, uses not in city.The application of biomass fuel, actual mainly biomass molding fuel (BiomassMouldingFuel, it is called for short " BMF "), it is as raw material using agricultural refuse, through pulverizing, mix, extrude, the technique such as drying, make various molding (such as bulk, graininess etc.), a kind of Novel clean-fuel that can directly burn.Biomass fuel caloric value is big, and caloric value is up to 7000～8000 kilocalories/kg in 3900 ~ 4800 kilocalories/about kg, the caloric value after carbonization.Its purity is high, does not produce the foreign material of heat without other, its carbon content 75～85, ash 3～6, water content 1～3, and absolutely not containing gangue, stone etc. does not generate heat the impurity of heat dissipation on the contrary, will be directly Reducing Cost in Enterprises.And not sulfur-bearing phosphorus, does not corrode boiler, can service life of prolonged boiler, enterprise is by benefited a great deal.Due to biomass fuel not sulfur-bearing phosphorus, sulfur dioxide and phosphorus pentoxide is not produced during burning, thus it is not result in that acid rain produces, not atmosphere pollution, free from environmental pollution, sanitation and hygiene, feed intake conveniently, reducing the labor intensity of workman, significantly improve work situation, minimizing is used for the cost in terms of labour force by enterprise.After burning, ash quarrel is few, greatly reduces the place stacking coal quarrel, reduces muck removal expense.Meanwhile, the ashes after biomass fuel combustion are the high-quality organic potassic fertilizers that grade is high, recyclable make profits.Country advocates clean energy resource energetically, for the use country subsidy per ton 150 yuan of biomass fuel.
Conduction oil, is the former name of " heat medium oil " in GB/T 4016-1983 " oil product vocabulary of terms ", and English name is Heat transfer oil, for the specialized oil product of a class better heat stability of indirect transfer heat.Owing to it has homogeneous heating, homoiothermic precise control, can produce high temperature under low-steam pressure, heat-transfer effect is good, energy-conservation, conveying and the feature such as easy to operate, is widely used in various occasion in recent years, and its purposes and consumption get more and more.Conduction oil has the performance of heat resistanceheat resistant cracking and chemical oxidation, and heat transfer efficiency is good, rapid heat dissipation, and heat stability is fine.Conduction oil has the following characteristics that under conditions of almost normal pressure as industry oil heat transfer medium, it is possible to obtain the highest operation temperature.I.e. can be substantially reduced operation pressure and the safety requirements of high-temperature heating system, improve the reliability of system and equipment；Different temperatures heating, the process requirements of cooling can be met within the scope of wider temperature, or in same system, realize the technological requirement of high-temperature heating and sub-cooled with same conduction oil simultaneously.I.e. can reduce the complexity of system and operation；Eliminate water treatment system and equipment, improve system thermal efficiency, decrease the maintenance workload of equipment and pipeline.I.e. can reduce initial cost and the operating cost of heating system；In the case of cause of accident causes system leak, conduction oil and naked light are likely to occur burning when meeting, and this is the problem that heat-conducting oil system is existing compared with water vapor system.But under conditions of not leaking, owing to heat-conducting oil system works under lower pressure, therefore its processing safety is higher than water and vapour system.Conduction oil is compared with another kind of high-temperature heat-transfer medium fused salt, when operating temperature and being more than 400 DEG C, fused salt in the price of heat transfer medium and has absolute advantage compared with conduction oil in terms of service life, but is in obvious inferior position in other side, especially in terms of the complexity of system operation.
