Description

A kind of wet desulfuration tower that is used for biogas desulfurization
[technical field]
The utility model relates to biogas desulfurization tower technology field, specifically a kind of wet desulfuration tower that is used for biogas desulfurization.
[background technology]
The purification purification techniques of biogas is a very important link in the biogas recycling, CO 2, H 2The existence of non-combustible gas such as S and water vapour reduces the biogas calorific value greatly, therefore, before using biogas it is purified the efficient utilization that purification can realize biogas.At present the purification purification techniques of biogas mainly is desulfurization, decarburization, dewaters and remove other not combustion-supporting impurity.
Sulphur is mainly with H in the biogas 2The S form exists, H 2S is poisonous, and very strong corrodibility is arranged, and the rotten egg taste of be difficult to hearing is arranged, although its content must be removed because the difference of fermentation raw material changes to some extent, in order to avoid corrode compressor, gas storage tank and engine etc.; Environmental Protection in China standard strict regulation, when utilizing biogas, H in the biogas 2S content must not surpass 0.02g/m 3Therefore, desulfurization becomes a requisite important step in the marsh gas purifying.
Desulfurization technology mainly contains dry method, wet method and biological process desulfurization etc.Wherein wet method is simple with its less investment technical process, operation is continuous and the desulfuration efficiency advantages of higher causes people's great attention.The wet desulphurization technology is to utilize specific solvent to contact with back flow of gas and remove wherein H 2S, solvent is reuptaked after regenerating, and is applicable to that the processing gas quantity is big, the gas sweetening engineering that sulphur content is high.
[utility model content]
At sweetening process in the marsh gas purifying thionizer, the utility model proposes a kind ofly change biogas fortune path, make enter thionizer biogas in the shape of a spiral shape slowly rise, make that biogas is longer with the duration of contact of absorption agent, sweetening effectiveness is than the better a kind of modified version thionizer structure of traditional wet desulfuration tower.
Designed a kind of wet desulfuration tower that is used for biogas desulfurization for achieving the above object, it is characterized in that:
A, described thionizer bottom are provided with fluid storage tank, described thionizer waist is inserted with the biogas intake ducting, the biogas intake ducting is inserted to the thionizer inside center and is connected with blast cap, the blast cap top is provided with liquid distributor, liquid distributor is provided with atomizing sprayer, the atomizing spray mouth links to each other with liquid distributor, described thionizer top is provided with mist eliminator, mist eliminator is provided with the methane outlet pipeline, described fluid storage tank bottom and pump entrance are by pipe connection, its outlet of described water pump and atomizing spray mouth constitute whole by pipe connection;
When b, work, biogas enters blast cap by the biogas intake ducting, blast cap slow rotation at the uniform velocity, biogas goes out behind the blast cap that curl slowly rises in thionizer, absorption agent is beaten to the atomizing spray mouth by water pump, enters thionizer through liquid distributor to the spraying gun atomizing, slowly descends under action of gravity, meet with the biogas that rises, with the H of biogas in rising and absorption biogas 2S, after moving to behind the cat head through gas-liquid separator separates, absorbing, gas up to standard is discharged after by the mist eliminator demist, and liquid-absorbant absorbs H 2Descend behind the S, to fluid storage tank, recycle, and in the decline process, contact with the biogas that rises once more, absorb H 2S.
Described atomizing sprayer is the upper-spraying type atomizing sprayer.
The utility model improves thionizer according to desulfurization characteristic in the biogas wet desulfuration tower.On the basis that does not change other performances of thionizer itself, by changing the movement path of gas in thionizer, increase the residence time of biogas in thionizer and increase it and the duration of contact of absorption agent, further improve biogas desulfurization efficient; The window of filler bracing or strutting arrangement and dismounting filler is saved without filler in thionizer inside, avoids having reduced technology because of filler generation blockage problem, also saves cost when alleviating tower body weight.
[description of drawings]
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1, methane outlet pipeline 2, mist eliminator 3, atomizing sprayer 4, liquid distributor 5, biogas inlet pipeline 6, atomizing spray mouth 7, water pump 8, fluid storage tank 9, blast cap
[embodiment]
Further specify below below in conjunction with accompanying drawing the utility model being done:
As shown in drawings, thionizer described in the utility model bottom is provided with fluid storage tank, described thionizer waist is inserted with the biogas intake ducting, the biogas intake ducting is inserted to the thionizer inside center and is connected with blast cap, the blast cap top is provided with liquid distributor, liquid distributor is provided with atomizing sprayer, the atomizing spray mouth links to each other with liquid distributor, described thionizer top is provided with mist eliminator, mist eliminator is provided with the methane outlet pipeline, described fluid storage tank bottom and pump entrance are by pipe connection, and its outlet of described water pump and atomizing spray mouth constitute whole by pipe connection.
Reactions steps in the thionizer is:
Biogas enters blast cap from the inlet mouth of thionizer bottom, blast cap slow rotation at the uniform velocity, biogas goes out behind the blast cap that curl slowly rises in thionizer, absorption agent enters thionizer top after atomizing through spraying gun, under action of gravity, slowly descend, meet with the biogas that rises, to rising, move to behind the cat head through gas-liquid separator with biogas.Gas up to standard after the absorption enters air compressor machine after by the mist eliminator demist.And liquid-absorbant is absorbing H 2Enter fluid storage tank behind the S, and in the decline process, contact with the biogas that rises once more, absorb H 2S.
And with water pump it is taken away, this liquid-absorbant can be regenerated it, recycles again then.
