  The harmful chemical substance removing agent of the present invention is for trapping and removing harmful chemical substances contained in the air, and is at least one of dredged material and an extract extracted from the dredged material. Is included.

  Among these, as firewood, timber logs, flat plates, or pulverized products obtained by pulverizing these materials, sawdust, chips, etc. can be used. It is possible to use scraps, sawdust, sawdust, etc., which are generated when manufacturing pillars, beams and other building materials.

  In addition, as an extract of dredging material, the dredged material, in particular, grinded material of grinded material, ground powder, chips, mill ends, sawdust, sawdust, etc., is immersed in water or hot water, and is statically left for a predetermined time. It is possible to use a mixture of various natural ingredients that serve to trap harmful chemical substances contained in the firewood, extracted by stirring for a predetermined time.

  As a result, various natural components act in a complex and synergistic manner, and harmful chemical substances can be quickly and efficiently removed from the air.

  The extract is preferably used in the form of a mixed solution in which various natural components extracted are mixed in the water used for extraction in order to save the labor of separation and purification. Moreover, it is preferable to remove the brazing material after the extraction treatment from the mixed solution, but in some cases, the brazing material may be used while being mixed.

  As the extract of the straw material used in the present invention, in particular, the firewood (preferably, the ground material, ground powder, chips, mill ends, sawdust, sawdust, etc.), together with water, in a sealed container, For the liquid that has been extracted by heating and stirring for a predetermined time, the liquid is added to a new brazing material, and then heated and stirred for a predetermined time in an airtight container to perform an extraction process again. A high-concentration extract (a mixed solution in which various extracted natural components are mixed in water) obtained by performing at least once is preferable.

  By using such an extract, harmful chemical substances can be removed from the air more quickly and efficiently.

  The treatment conditions are not particularly limited, but for example, the heating temperature is preferably 60 to 100 ° C. in any extraction process. When the heating temperature is less than 60 ° C., depending on the processing time, the concentration of the final extract becomes insufficient because the amount of natural components extracted into the liquid is small in each extraction process. There is a fear. Moreover, in order for heating temperature to exceed 100 degreeC, it is necessary to improve the pressure | voltage resistance of an airtight container, installation cost etc. increase, and there exists a possibility that an extract cannot be obtained cheaply and easily.

  Moreover, when the heating temperature is within the above range, the time for each extraction process is preferably 1 to 3 days. If the treatment time is less than one day, the amount of natural components extracted into the liquid is small in each extraction treatment, and the final extract concentration may be insufficient. In addition, even if the treatment is performed for more than 3 days, the concentration of the extract cannot be increased any more, and the extracted components deteriorate and the function of capturing harmful chemical substances decreases. There is a risk.

  For stirring under heating, for example, a pump for circulating the liquid in the sealed container and a pipe are connected to the sealed container, and a boiler for heating the liquid is connected in the middle of the pipe. Then, by driving the pump and circulating the liquid in the pipe, the liquid circulating in the pipe by operating the boiler while stirring the liquid in the sealed container is, for example, within the above range. What is necessary is just to heat continuously or intermittently so that the inside of temperature may be maintained.

  FIG. 1 is an explanatory diagram showing an example of a processing apparatus used for the extraction process.

  The processing apparatus shown in the figure includes a sealed container 1 for performing extraction processing by mixing water and drought material, and a liquid after treatment in the sealed container 1 is mixed with new drought material to perform extraction processing again. A sealed container 2 for performing, a pump 3 for circulating the liquid in both the sealed containers 1 and 2, a boiler 4 for heating the liquid, and a liquid extract produced by the extraction process And a storage tank 5.

  Further, the sealed container 1 and the pump 3 drive the pump 3 to take in liquid from the vicinity of the bottom of the sealed container 1 and supply it to the pump 3 as indicated by solid arrows in the drawing. For this purpose, the pipe 6 is connected to the pipe 7 for returning the liquid discharged from the pump 3 to the sealed container 1.

  Further, in the middle of the pipe 6, a pipe 8 for taking in liquid from the vicinity of the bottom of the sealed container 2 by driving the pump 3 is connected via a switching valve 9 and the liquid flowing through the pipe 7. Is connected to a pipe 10 for heating the boiler 4 into the boiler 4 and heating it.

  In the middle of the pipe 7, a pipe 11 for returning the liquid to the sealed container 2 by driving the pump 3 is connected via a switching valve 12. Further, in the middle of the pipe 11, a pipe 13 for sending the liquid extract produced by the extraction process to the storage tank 5 by driving the pump 3 is connected via a switching valve 14.

  Furthermore, a filter 15 is provided in the middle of the pipe 13 to remove solid content such as straw from the liquid extract produced by the extraction process.

  In order to obtain an extract of dredged material using the processing apparatus of the figure, first, a predetermined amount of dredged chip and a predetermined amount of water are accommodated in the sealed container 1. It is preferable that the amount of the brazing material and the water to be accommodated is approximately the same volume.

  Next, the sealed container 1 is closed, the switching valve 9 is connected between the sealed container 1 and the pump 3, the sealed container 2 is disconnected from the pump 3, the switching valve 12 is connected between the pump 3 and the sealed container 1, and the pump 3- Set between the sealed containers 2 in a closed state.

  Next, the pump 3 is driven to circulate the liquid through the sealed container 1, the pipe 6, the pump 3, and the pipe 7, thereby operating the boiler 4 while stirring the mixture in the sealed container 1. The circulating liquid is heated to a predetermined temperature (preferably 60 to 100 ° C.).

  Then, this heating and stirring state are continued for a predetermined time (preferably 1 to 3 days), and components are extracted from the brazing material in the sealed container 1.

  The end point of extraction can be determined from the pH of the liquid. That is, as described above, the pH of the liquid in the sealed container 1 that started extraction from approximately the same volume of water and straw was initially around 7, but the pH of the liquid from the straw was natural. Although it gradually decreases as the components are extracted, if it decreases to about 6.0 to 6.5, the natural components extracted from the strawberries disappear, so the pH does not decrease any further. Therefore, it can be determined that this time is the end point of extraction.

  In parallel with this extraction operation, a predetermined amount (preferably, approximately the same volume as the liquid in the sealed container 1) of a wood chip or the like is accommodated in the sealed container 2, and the switching valve 14 is connected to the pump 3 -Set between the sealed containers 2 and shut off between the pump 3 and the storage tank 5.

  As described above, when it is determined from the pH of the liquid in the sealed container 1 that the extraction has reached the end point, the driving of the pump 3 is temporarily stopped while the driving of the pump 3 is continued. In this state, the switching valve 12 is shut off between the pump 3 and the sealed container 1 and switched between the pump 3 and the sealed container 2 to a connected state, and is again driven when the pump 3 is stopped once. If it does so, the liquid in the airtight container 1 will be sent to the airtight container 2 through the piping 6, the pump 3, the piping 7, and the piping 11. FIG.

  Next, when it is confirmed that almost all of the liquid in the sealed container 1 has been sent to the sealed container 2, the switching valve 9 is shut off between the sealed container 1 and the pump 3, and between the sealed container 2 and the pump 3 Switch to connected state. And by continuing the drive of the pump 3 and circulating the liquid through the sealed container 2, the pipe 8, the pipe 6, the pump 3, the pipe 7, and the pipe 11, while stirring the mixture in the sealed container 2, The boiler 4 is operated, and the circulating liquid is heated to a predetermined temperature (preferably 60 to 100 ° C.).

  This heating and stirring state are continued for a predetermined time (preferably 1 to 3 days), and components are extracted from the brazing material in the sealed container 2.

  The end point of extraction can also be determined from the pH of the liquid. That is, as described above, the pH of the liquid in the sealed container 2 that started the extraction from the liquid and the straw of almost the same volume was initially around 6.0 to 6.5. However, when natural components are extracted from the firewood, it gradually decreases. However, when the natural components are reduced to about 5.5 to 6.0, the natural components extracted from the firewood disappear, and therefore, the natural components are not further reduced. Therefore, it can be determined that this time is the end point of extraction.

  As described above, when it is determined from the pH of the liquid in the sealed container 2 that the extraction has reached the end point, the driving of the pump 3 is temporarily stopped while the driving of the pump 3 is continued. In this state, the switching valve 14 is shut off between the pump 3 and the sealed container 2 and switched between the pump 3 and the storage tank 5 to a connected state, and when the pump 3 is temporarily stopped, it is driven again. As a result, the liquid in the airtight container 2 is removed by the filter 15 provided in the middle of the pipe 13 while the solid content such as the chip of the brazing material is removed, while the pipe 8, the pipe 6, the pump 3, the pipe 7, the pipe 11, and It is sent to the storage tank 5 through the pipe 13 to complete a series of processing, and a liquid extract is obtained.

  It is preferable that the extract stored in the storage tank 5 is kept out of air as much as possible. This is because, when exposed to air, the oxidation reaction proceeds and the action of trapping harmful chemical substances decreases.

  In addition, the processing apparatus of a figure adds the said liquid to the new brazing material with respect to the liquid which extracted the heating material and water in the airtight container 1 by heating and stirring in the airtight container 2, and the airtight container 2 is shown. Inside, only one sealed container 2 was provided in order to carry out the heating, stirring and extraction operation once again. However, if this treatment is performed twice or more, higher concentration extraction is performed. You can get things. For this purpose, one or more sealed containers 2 may be added between the sealed container 2 and the storage tank 5 in the figure.

  In addition, if the water and straw before extraction processing in the processing apparatus shown in the figure are stored in a mixed state for a certain period of time in advance, the components are extracted during that period, so the concentration of the extract is increased. be able to.

  In addition to the method described above, the processing method for obtaining the extract of firewood is, for example, immersed in water or hot water and left still for a predetermined time, or predetermined. The method of stirring for a time is mentioned. In addition, for example, a predetermined amount of water and dredged material are charged in a reaction kettle, the reaction kettle is sealed, heated and pressurized for a predetermined time, and then the steam vent valve of the reaction kettle is opened at once. Further, after discharging steam and light components out of the extracted components to the outside of the kettle, it is possible to adopt a method of removing the dredged material from the liquid in the kettle.

Ammonia reacts with formaldehyde in the air to produce a solid reaction product at room temperature and normal pressure. Hazardous chemical substances contained, particularly formaldehyde, can be removed from the air more quickly and efficiently.

  Although the effects described above are improved as the amount of ammonia added is increased, the ammonia odor is generated by the surplus ammonia that cannot be captured by the firewood and its extract, so the amount of ammonia added is preferably as small as possible.

  Although the specific range of the addition amount of ammonia is not particularly limited, the extraction with the pH of 5.5 to 6.0 is performed by performing the re-extraction process with the sealed container 2 only once, as described above. It is preferable to add 10% aqueous ammonia in the range of 0.05 to 0.15 cc with respect to 100 cc of the product.
