Description

Coal gas desulfurization tower with the Multi-layer sprinkling structure
Technical field
The utility model relates to a kind of coal gas desulfurization tower.
Background technology
According to the requirement of the laws and regulations such as the Law on Environmental Protection of the People's Republic of China, " The Law of the People's Republic of China on the Prevention and Control of Atmospheric Pollution ", various sulfur-bearing coals are made the coal gas for burning, all need to remove the sulphur in coal gas.Sulphur in coal gas is deviate from two kinds, hydrogen sulfide before can being divided into the sulfur dioxide deviate from after burning and burning, because of the burning after exhaust gas volumn more, complex treatment process, coal gas desulfurization adopts the method for deviating from sulfur dioxide before burning mostly at present, the equipment that this method adopts now normally gets up the device combinations such as eddy flow tower, packed tower or gas-liquid separation tower, the occupation area of equipment of this combining structure is large, the resistance that during processing, coal gas is subject to is also larger, filler easily stops up, and cleaned and changed all very difficult.
The utility model content
For above-mentioned deficiency, the utility model provides a kind of easy cleaning to change, floor space is little, the coal gas desulfurization tower with the Multi-layer sprinkling structure that filler stops up can not occur.
The utility model is to realize by such technical scheme: with the coal gas desulfurization tower of Multi-layer sprinkling structure, lower leakage fluid dram, air inlet pipe, the lower spraying layer that comprises cylindrical shell, upwards sets gradually from cylinder body bottom, be fixed on the water receiving tank on cylinder inboard wall and be positioned at the water receiving tank bottom upper leakage fluid dram, be supported on the water fender on water receiving tank, upper spraying layer, demister and escape pipe, wherein, the external diameter of water fender is greater than the internal diameter of water receiving tank.
Described water fender is obliquely installed from inside to outside, flow to water receiving tank smoothly thereby can make from upper spraying layer doctor solution out.
Described water receiving tank is welded on the inwall of cylindrical shell, and the base plate of water receiving tank tilts from inside to outside, so that above-mentioned doctor solution is more successfully discharged from leakage fluid dram.
Be further, be provided with the shower nozzle that liquid at the bottom of doctor solution or desulfurization is atomized into droplet on described upper spraying layer and lower spraying layer, at the bottom of doctor solution or desulfurization, the liquid-drop diameter of liquid after this shower nozzle atomizing is 0.01 to 0.5 millimeter, thereby with liquid atomizing at the bottom of doctor solution or desulfurization, make itself and coal gas carry out better heat and mass transfer better; It is worth mentioning that, upper spraying layer and lower spraying layer all can be arranged to one or more layers.
Diameter at the bottom of the doctor solution between 0.2 to 0.3 millimeter or desulfurization the liquid quality greater than to 90% of drop gross mass.
Described demister is detachable piece formula combining structure, thereby can take out from hand-hole easily.
Owing to having adopted said structure, the beneficial effects of the utility model are as follows: at the bottom of the doctor solution in the middle part of the Multi-layer sprinkling structure makes in tower and the desulfurization of bottom, liquid fully mixes mutually, during the lower spraying layer of coal gas process, at the bottom of desulfurization after atomizing, liquid and coal gas conduct heat and mass transfer for the first time, remove most of sulfur dioxide in coal gas, when coal gas passed through spraying layer again, the doctor solution after atomizing conducted heat with it and mass transfer again, makes desulfurization more thorough; And, the used doctor solution of upper spraying layer is after water fender is collected, flow into the bottom of water receiving tank and discharge from upper leakage fluid dram, at the bottom of the used desulfurization of lower spraying layer, liquid is discharged through the lower leakage fluid dram that is positioned at cylinder body bottom, therefore, use this coal gas desulfurization of cover tower can reach simultaneously comparatively desirable desulfurization state, its floor space is little, structure is comparatively simple, resistance that coal gas rises in processing procedure is less, thereby raising desulfuration efficiency, filler can not occur stop up, clean and change all very convenient.
Description of drawings
Fig. 1 is the coal gas desulfurization tower structure sketch of Multi-layer sprinkling structure in this case embodiment.
The specific embodiment
In order more to be expressly understood the purpose of this utility model, technical scheme and beneficial effect, below in conjunction with accompanying drawing, the utility model is described further, but protection domain of the present utility model is not limited in following examples.
As shown in Figure 1, coal gas desulfurization tower with the Multi-layer sprinkling structure, comprise cylindrical shell 1, the lower leakage fluid dram 2, air inlet pipe 3, the lower spraying layer 4 that upwards set gradually from cylindrical shell 1 bottom, be fixed on the water receiving tank 5 on cylindrical shell 1 inwall and be positioned at water receiving tank 5 bottoms upper leakage fluid dram 6, be supported on water fender 7, upper spraying layer 8, demister 9 and escape pipe 10 on water receiving tank 5, wherein, the external diameter of water fender 7 is greater than the internal diameter of water receiving tank 5; Described water fender 7 is obliquely installed from inside to outside; Described water receiving tank 5 is welded on the inwall of cylindrical shell 1, and the base plate of water receiving tank 5 tilts from inside to outside; Be provided with the shower nozzle that liquid at the bottom of doctor solution or desulfurization is atomized into droplet on described upper spraying layer 8 and lower spraying layer 4, at the bottom of doctor solution or desulfurization, the liquid-drop diameter of liquid after this shower nozzle atomizing is 0.01 to 0.5 millimeter; Diameter at the bottom of the doctor solution between 0.2 to 0.3 millimeter or desulfurization the liquid quality greater than to 90% of drop gross mass; Described demister 9 is detachable piece formula combining structure.
As shown by arrows in FIG., coal gas enters from the air inlet pipe 3 of cylindrical shell 1 bottom, down pass into liquid at the bottom of desulfurization in spraying layer 4, shower nozzle in lower spraying layer 4 makes it be atomized into droplet, thereby conduct heat for the first time and mass transfer with coal gas, remove the most of sulfur dioxide in coal gas, at the bottom of the desulfurization after use, liquid collects in lower leakage fluid dram 2 and the discharge of cylindrical shell 1 bottom; Coal gas continues to rise under the gas pressure effect, by the gap between water receiving tank 5 and water fender 7, conduct heat and mass transfer again with by the doctor solution that sprays after spraying layer 8 atomizings, remove remaining sulfur dioxide in coal gas, doctor solution after use is after water fender 7 is collected, from the marginal flow of water fender 7 to water receiving tank 5, again by upper leakage fluid dram 6 discharges that are positioned at water receiving tank 5 bottoms, the fit structure of this water fender 7 and water receiving tank 5, at the bottom of making above-mentioned doctor solution and desulfurization, liquid separates fully, further improves the efficient of desulfurization.
