The desulfurizer has the beneficial effects that the applicability is aimed at the property of the unstable biomass methane flow and hydrogen sulfide content, under the condition that the lowest operating cost is ensured, the desulfurizer can meet various working condition applicable requirements on that process requirement is satisfied through the desulfurization from the high-concentrated hydrogen sulfide content and from the low-concentrated hydrogen sulfide content, therefore, the operation cost is reduced.
Description
Technical field
The utility model belongs to biomass energy development and use field, designs a kind of biomass marsh gas high efficient mixed staged desulfurizer especially.
Background technology
At present, in the existing chemical technique, hydrogen sulfide commonly used is deviate from technology and is comprised wet desulphurization, dry desulfurization, biological desulphurization etc., on the whole, from the stability of tolerance and the content of makings hydrogen sulfide, there is the scope of application in various sulfur methods, and general wet desulphurization is applicable to and removes high-concentration hydrogen sulfide, but running cost is higher, dry desulfurization is applicable to and removes low concentration hydrogen sulphide, but needs periodic replacement sweetening agent, the biological desulphurization cost is lower, but shock-resistant ability is relatively poor, less stable.
Biomass marsh gas prepares the Sweet natural gas technical process and mainly comprises technologies such as dehydration, desulfurization, decarburization, because the biomass marsh gas source is different, the equal characteristic of concentration of hydrogen sulfide height big, makings that the tolerance that has biogas fluctuates, existing chemical industry sulfur removal technology is difficult to satisfy biomass marsh gas desulfurization requirement, has technological deficiency aspect suitability.
Summary of the invention
For solving above technical deficiency, the utility model provides a kind of efficient height, stability is high, cost is low biomass marsh gas high efficient mixed staged desulfurizer.
The utility model is realized by following measure:
A kind of biomass marsh gas high efficient mixed of the utility model staged desulfurizer, comprise biogas pipeline, wet desulfuration tower and dry desulfurization jar, the air outlet of described wet desulfuration tower is connected by biogas pipeline with the inlet mouth of dry desulfurization jar, and the biogas source is communicated with the inlet mouth of wet desulfuration tower by biogas pipeline and the inlet mouth and the biogas pipeline of dry desulfurization jar is provided with the trip switch device.
Above-mentioned trip switch device comprises the magnetic valve of the proofing unit, control wet desulfuration tower or the switching of dry desulfurization canister incoming gas biogas pipeline that detect concentration of hydrogen sulfide and controls the controller of magnetic valve break-make according to detected concentration of hydrogen sulfide.
The beneficial effects of the utility model are: suitability is at biomass marsh gas flow and the unsettled characteristic of hydrogen sulfide content, the utility model device is under the condition of guaranteeing the minimum operation cost, can either satisfy from high-concentration hydrogen sulfide content being removed to processing requirement, can satisfy the multi-state adaptability of technology requirement that is removed to processing requirement from low in hydrogen sulphide content again.Reduced running cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 wet desulfuration tower, 2 biogas pipelines, 3 dry desulfurization jars, 4 trip switch devices.
Embodiment
As shown in Figure 1, the device integral body mainly comprise slightly take off, essence is taken off, three aspects of trip switch.The air outlet of wet desulfuration tower 1 is connected by biogas pipeline 2 with the inlet mouth of dry desulfurization jar 3, and the biogas source is communicated with the inlet mouth of wet desulfuration tower 1 by biogas pipeline 2 and the inlet mouth and the biogas pipeline 2 of dry desulfurization jar 3 is provided with trip switch device 4.Slightly taking off the employing wet processing, mainly is that the biogas in the biogas source is handled in wet desulfuration tower 1, and being characterized in can be big at the biogas flow, when hydrogen sulfide content is high, effectively remove most of hydrogen sulfide, and desulphurization cost is relatively low; Essence is taken off the employing dry process, mainly is the biogas in the biogas source is handled in dry desulfurization jar 3, and characteristics are biogas hydrogen sulfide contents when low, and are simple to operate, can satisfy processing requirement; Trip switch device 4 mainly comprises the magnetic valve of the proofing unit, control wet desulfuration tower 1 or 2 switchings of dry desulfurization jar 3 air inlet biogas pipelines that detect concentration of hydrogen sulfide and controls the controller of magnetic valve break-make according to detected concentration of hydrogen sulfide.Be used to monitor the concentration of hydrogen sulfide,, thereby realize the transformation pattern simultaneously according to concentration range control wet desulfuration tower 1 air inlet or 3 air inlets of dry desulfurization jar.According to biogas flow and hydrogen sulfide content, mainly be divided into two kinds of operating mode:
1, slightly take off, essence takes off the ladder operation
Slightly take off, to take off the ladder operation mainly be when detecting the biogas concentration of hydrogen sulfide when higher to essence, biogas in the trip switch device 4 control biogas sources only feeds in the wet desulfuration tower 1, at first carrying out wet method crude takes off, the biogas hydrogen sulfide content is reduced about 90%, feed the dry desulfurization jar 3 from wet desulfuration tower 1 air outlet then, take off through essence again and reach processing requirement.The scope of application is for designing in the maximum biogas flow range hydrogen sulfide content 〉=1000ppm.
2, essence is taken off independent operating
It mainly is when detecting the biogas concentration of hydrogen sulfide when low that essence is taken off independent operating, biogas in the trip switch device 4 control biogas sources only feeds in the dry desulfurization jar 3, directly pass through dry removal, effectively reduce running cost, the scope of application is for designing in the maximum biogas flow range hydrogen sulfide content≤1000ppm.Two kinds of operating mode are controlled by monitor control system, also can be regulated by Artificial Control.
The foregoing description is described to be in order to specify this patent; though describe by specific term in the literary composition; but can not limit the protection domain of this patent with this; being familiar with the personage of this technical field can be after the spirit of understanding this patent and principle change or revises it and reach equivalent purpose; and this equivalence change and modification all should be covered by the claim scope and define in the category.
