Abstract
The invention provides a low resistance, low cost and energy saving active carbon sulfur free tower, with support post inside the shell with supporting plate on it, carbon layer on the supporting plate, acid separation layer whose top has active carbon layer is above the carbon layer, with protective net outside the active carbon whose top having spray device, center cavity lower being the acid storage slot, one end outside the tower through the acid through channel connected with the acid storage slot bottom, bottom of the tower shell, air inlet tube connected to the inner cavity outside the tower, top of the center cavity connected to the gas outlet. In this way, the production cost is low, gas running smoothly, small in resistance, free from big power exhauster, less in power consumption, low in running cost, strong in active carbon addition and falling out, which can be reutilized with better performance.
Description
Technical field
The invention provides a kind of desulfurizer of fire coal boiler fume.
Background technology
Contain a large amount of harmful substances such as sulfur dioxide in the fire coal boiler fume, therefore, it be removed, to adapt to environmental requirement.Wherein a kind of desulfurizer is an activated carbon tower.Existing activated carbon tower complex structure, the manufacturing cost height, the flue gas running resistance is big, need to adopt high-power air-introduced machine, and power consumption is big, causes desulfurizing tower manufacturing, operating cost higher.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of activated carbon tower, to alleviate flue gas running resistance and operating cost.
The present invention realizes like this, activated carbon tower, it has the tower body shell, in the tower body shell support column is arranged, supporting plate is arranged above the support column, charcoal layer basis arranged on the supporting plate, the charcoal layer has acid separating layer above the basis, active carbon layer is arranged above the acid separating layer, the active carbon layer outer surface has protection network, there are ejecting device, active carbon layer in the active carbon layer top, acid separating layer, middle part, charcoal layer basis constitutes central cavity, and the central cavity bottom is an acid accumulator storage, the other end of the acid guiding tube that one end communicates with the acid accumulator storage bottom is positioned at the tower body outside, the venturi air inlet pipe of installing in the bottom of tower body shell communicates with the tower body shell inner cavity, and central cavity top communicates with smoke outlet tube, and venturi air inlet pipe air inlet top is equipped with another ejecting device.
Adopt the activated carbon tower of said structure, rational in infrastructure, manufacturing cost is low, and the flue gas operation is happy, and running resistance is little, needn't adopt powerful air-introduced machine, power consumption is little, and operating cost is low, and absorption, the desorption of active carbon are effective, the dilute sulfuric acid that desorption produces can be drawn tower and be added to utilize, and serviceability is good.
Fig. 1 is the schematic diagram of structure of the present invention.
Fig. 2 is the A-A profile of Fig. 1.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present invention and operation principle.
As shown in drawings, the present invention's activated carbon tower, it has tower body shell 7, support column 3 is arranged in the tower body shell, supporting plate 4 is arranged above the support column, charcoal layer basis 5 arranged on the supporting plate, the charcoal layer has acid separating layer 6 above the basis, active carbon layer 8 is arranged above the acid separating layer, the active carbon layer outer surface has protection network 12, there are ejecting device 9, active carbon layer in the active carbon layer top, acid separating layer, middle part, charcoal layer basis constitutes central cavity 10, and the central cavity bottom is an acid accumulator storage 13, the other end of the acid guiding tube 14 that one end communicates with the acid accumulator storage bottom is positioned at the tower body outside, the venturi air inlet pipe 1 of installing in the bottom of tower body shell communicates with the tower body shell inner cavity, and central cavity top communicates with smoke outlet tube 11, and venturi air inlet pipe air inlet top is equipped with another ejecting device 2.
On the smoke outlet tube 11 air-introduced machine is installed.Acid separating layer is made of granular material such as crushed granite, quartz sand etc.Acid accumulator storage is in the below medial surface of acid separating layer.Obviously, each ejecting device is made of shower nozzle and water pipe.The layout of the shower nozzle on the ejecting device 9 is corresponding with the shape of cross section of active carbon layer.As can be seen from Figure 2, the cross section of active carbon layer is the ring-type of rectangle, and the total length of this ring can reach very long size in theory, and therefore, filter area is bigger.Under set situation of charcoal absorption time, the thickness that bigger filter area can corresponding reduction active carbon layer, thus reduce the resistance of active carbon layer to flue gas.
The downward-sloping 15-20 of the airintake direction of venturi air inlet pipe ° angle.Therefore, flue gas dives to entering in the 10-15 centimetre of dark water that tower body bottom maintains always in the venturi mode and carries out water bath dust-removing.In addition, flue gas fully contacts with water droplet through ejecting device 2 spray, and is last, and flue gas is along rising on the space between tower body outer casing inner wall and active carbon layer, acid separating layer, charcoal layer basis, the support column periphery.Because less Venturi air inlet enters the bigger tower body bottom inner chamber in space suddenly from the space, and grit suction back weightening finish, grit is realized gravitational dust collection.Again and again in the process of dedusting, humidification, the cooling of flue gas have been realized at this.
The smoke distribution that rises is passed active carbon layer under the suction that air-introduced machine produces around the active carbon layer periphery.Because active carbon layer thickness is less, filter area is but very big, thereby flue gas resistance is very little, can alleviate the kinetic equation loss of air-introduced machine greatly.
After charcoal absorption is saturated, carry out desorption by 9 pairs of active carbon layer sprays of ejecting device.Can pass through automaton (as magnetic valve), the action of ejecting device be controlled automatically according to the needs of desulfurizing tower.
The dilute sulfuric acid that produces during the active carbon layer desorption flows downward along active carbon layer, flows out through acid separating layer, enter in the acid accumulator storage of central cavity bottom, after acid guiding tube draw outside the tower.
Because the inner space of this desulfurizing tower is very big, therefore, in case of necessity, the staff can enter the outside in the active carbon layer the flue gas air inlet, go out the headroom and check, keep in repair, this also is that former activated carbon tower is irrealizable.
