Description
Technical field
The invention belongs to chemical technology fields, are related to the final treatment techniques of cracking waste plastics fuel-firing gas-firing recycled water.
Background technology
Existing market and production greatly improve the purity requirement of fuel oil, combustion gas.Fuel oil, combustion gas are because the impurity such as aqueous vapor are deposited
Causing calorific value low, utilization is more difficult.Existing natural gas dehydration technique is divided into four kinds：It is solvent absorption, solid absorption method, straight
Connect cooling method and membrane separation process.But water content is high in product in waste plastics pyrolysis fuel oil processed, gas process for the prior art, leads
Cause product calorific value low.And the prior art is easy to be influenced by environment and transport, causes many places that can not implement.Cost
Height, higher cost cause natural gas expense to increase.Efficiency is low so that pure natural output efficiency reduces.It is split in waste plastics
The moisture that about 15-20% can be formed during solution fuel oil, combustion gas, because oil-containing, PH containing chlorine are exceeded so can not direct emission.
Invention content
The purpose of the present invention is to provide the final treatment techniques of cracking waste plastics fuel-firing gas-firing recycled water, of the invention has
Beneficial effect is to be effectively separated recycling to moisture, gas in waste plastics thermal decomposition product, reduces pollution.
The technical solution adopted in the present invention is to follow the steps below：
Step 1：Level-one water-oil separating, oil recycle；
Step 2：Two level gravity precipitation removal large granular impurity；
Step 3：Three-level quartz sand filtration；
Step 4：Level Four pH value neutralization step is on pipeline equipped with online chloride test instrument detection chloride ion content letter
Number PLC hosts are fed back to, exporting quantitative hypo solution by PLC control constant displacement pumps achievees the effect that neutralization.
Further, separation temperature is 30 degree in step 1.
Further, quartz sand is replaced with other same sex materials in step 3.
Further, neutralizer selects other same sex metallic substances to replace in step 4.
Description of the drawings
Fig. 1 is present invention process flow diagram.
Specific implementation mode
The present invention is described in detail With reference to embodiment.
Present invention process is as shown in Figure 1, use level-one water-oil separating (temperature is 30 degree or so raising separative efficiency), oil returns
It receives and utilizes, two level gravity precipitation removes large granular impurity, is directly flowed by pipeline after three-level quartz sand filtration, in level Four pH value
Signal is fed back to PLC hosts equipped with online chloride test instrument detection chloride ion content on pipeline with process, is controlled by PLC
Constant displacement pump exports quantitative hypo solution and achievees the effect that neutralization.Waste water reaches discharge standard after detection is qualified.
First order separation temperature range can suitably increase in the present invention.Third level quartz sand can use other same sex materials
Instead of.The replacement of other same sex metallic substances can be selected in fourth stage neutralizer.It is also an advantage of the present invention that：
1, at low cost, using most reasonably sequentially carrying out being detached, substantially reduce cost
2, efficient, disposable in place using level Four separation, centre is efficient without complicated link.
3, it is all conventional material to be not readily susceptible to the separation material that environmental area influences, this technology uses, not by traffic or
Other environment of person influence.
The above is only the better embodiment to the present invention, not makees limit in any form to the present invention
System, every any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
