Description
Technical field
The utility model belongs to rice husk carbonizing treatment facility, is specifically related to a kind of spraying cold slag device for the cooling vertical moving-bed gasification rice husk of lime-ash dry method.
Background technology
Vertical moving-bed gasification rice husk technology is a kind of New Environment Protection Technology that utilizes the discarded rice husk manufacture energy, and this gasification process technique can produce high-temperature ash in normal implementation process, must after cooling, enter the facility of slagging tap again.Conventional lime-ash cooling technology has two kinds at present, and one is that wet method is cooling, and warm sludge enters pond, then fishes for cold slag in pond, and advantage is that reliability is high, system is simple; Another is that dry method is cooling, utilize a heat exchanger that is applicable to lime-ash heat exchange, use air or water as heat-eliminating medium, in reclaiming warm sludge waste heat (output hot blast or hot water), realize the cooling object of dry method, advantage is to realize that dry method is slagged tap and recovery waste heat.The shortcoming of the cold slag technology of wet method is that waste heat can not reclaim and slag tap as wet slag, and the value of wet slag is low far beyond dry slag.In order to obtain dry slag, according to current technology, can only use expensive dry method slag cooler, not only system complex, operating requirement are high, and increased initial cost and occupation area of equipment, particularly the serviceability of dry method slag cooler is very poor, therefore cannot on middle-size and small-size equipment, use.For middle-size and small-size equipment, use dry method slag cooler not possess the reasonableness of Technical Economy, use wet method slag tap and make the potential utility value of lime-ash be subject to massive losses.
Summary of the invention
The purpose of this utility model is to provide the spraying cold slag device that a kind of reliability is high, can realize the cooling and lower-cost vertical moving-bed gasification rice husk of lime-ash dry method
For achieving the above object, the utility model provides following technical scheme: a kind of spraying cold slag device of vertical moving-bed gasification rice husk, comprise air-injection system and water coolant plenum system, the water-supply line of the delivery conduit of air-injection system and water coolant plenum system crosses at nozzle place.
Technique effect of the present utility model is: it is cooling that the mode that adopts aerosol combination is carried out dry method to grate lime-ash, and it is extremely sensitive to the control of temperature, and cooling reliability is high.

Embodiment
As shown in Figure 1, a kind of spraying cold slag device of vertical moving-bed gasification rice husk, comprises air-injection system and water coolant plenum system, and the delivery conduit 26 of air-injection system and the water-supply line 32 of water coolant plenum system cross at nozzle 10 places.At nozzle 10 places, water coolant is propelled by high pressure gas, water coolant atomization, the water coolant of atomization is beaten on lime-ash it is lowered the temperature, this type of cooling makes cooling more even, and the water coolant of atomization can evaporate rapidly, can make so again cooled lime-ash keep dry.
As shown in Figure 2, nozzle 10 necks are contraction-like, being horn-like from neck to exit opens gradually, the tube wall of nozzle 10 necks is provided with annular water chamber 11 outward, tube wall between the path of nozzle 10 and annular water chamber 11 is provided with into water aperture 12, nozzle 10 entrances are connected with the delivery conduit 26 of air-injection system, and annular water chamber 11 is connected with water coolant plenum system delivery conduit 32.Air-flow is when by the contraction-like neck of nozzle 10, and flow velocity can be accelerated, and therefore the pressure of nozzle 10 necks is less can produce negative pressure, and now the water coolant in annular water chamber 11 will be inhaled in the inner chamber of nozzle 10, is then gone out with air spray.
As shown in Figure 3, the delivery conduit 26 of air-injection system is provided with stopping valve 27, and the signal receiving end of stopping valve 27 is connected with temperature regulator 42, and temperature regulator 42 is connected with the temperature sensor 41 in pit.When the temperature in pit is during higher than set(ting)value, temperature regulator 42 is controlled stopping valve 27 and is opened, and when the temperature in pit is during lower than set(ting)value, 42 of temperature regulators control stopping valve 27 and cut out, and then realize temperature automatically controlled process.
As shown in Figure 3, air-injection system comprises air distributor 21, and the entrance pipe of air distributor 21 is connected with air pump 22, and delivery conduit 26 is connected with nozzle 10, and security device 25 is housed on air distributor 21.Air distributor 21 is equivalent to an interim hold-up vessel of high pressure gas, and air pump 22 is first sent into air air distributor 21 and pressurizeed, and then the air after pressurization sprays from nozzle 10 through pipeline again.
As shown in Figure 1, water coolant plenum system comprises water tank 30, and water tank 30 bottoms are provided with water outlet, and water outlet is communicated with the annular water chamber 11 on nozzle 10 by water-supply line 32.Water coolant plenum system, without any need for exterior power, only need to be communicated with water tank 30 with atmosphere, owing to there is negative pressure in nozzle 10 neck inner chambers, water coolant will be inhaled in the inner chamber of nozzle 10.
As shown in Fig. 1,3,4, the spraying cold slag device of vertical moving-bed gasification rice husk contains two or more nozzles 10, and each nozzle 10 is connected with a cooling water pipeline 32 with the air delivery conduit 26 of separately.Adopting multiple nozzles 10 is mainly in order to improve cooling precision, and temperature regulator 42 can regulate the nozzle 10 of respective numbers to open or cut out, thereby regulates the temperature of cooled lime-ash, and the quantity of nozzle 10 is more, and the precision of adjusting is higher.
As shown in Figure 3, air distributor 21 is provided with pressure transmitter 23, pressure transmitter 23 is connected with pressure controller 24, pressure controller 24 is connected with air pump 22, air pump 22 is frequency conversion air pump, security device 25 is U-shaped pipe Safety water seal, and Safety water seal one end is communicated with air distributor 21 bottoms, and the other end is communicated with atmosphere.In the time that the pressure in air distributor 21 is excessive, pressure controller 24 is controlled air pump 22 and is reduced power, in the time that the pressure in air distributor 21 is less than set(ting)value, pressure controller 24 is controlled air pump 22 increasing powers, thereby has ensured that the air pressure in air distributor 21 remains in a constant scope.Security device 25 adopts Safety water seal and does not use safety valve to be mainly because the relative barometric pressure in air distributor 21 is generally set as 5kPa between 10kPa, and the unlatching pressure of safety valve is all generally more than MPa level, therefore adopts Safety water seal sensitiveer.
As shown in Figure 1, water tank 30 water inlets are provided with float controlled valve 31, and the water level in water tank 30 is lower than the height at nozzle 10 places.When the water level in water tank 30 drops to after certain position, float controlled valve 31 will automatically be opened feed-tank 30 and supply water, water level rises to after certain position, and float controlled valve 31 cuts out automatically, and the water level of water tank 30 is in order to prevent water coolant gravity flow higher than the height of nozzle 10 positions.
