Description

Variable setting type deodorizer and deodorization method}

The present invention relates to a variable setting type deodorizer and a deodorization method, and more particularly, a basic setting value of the oxidation-reduction potential difference for the cleaning liquid before reaction with the odor gas for determining the condition of supplying the chemical to the cleaning liquid. The present invention relates to a variable setting type deodorizer and a deodorization method, which allow control necessary for proper treatment according to the odor concentration of the inflowing odor gas by varying according to the oxidation-reduction potential difference of the cleaning liquid after the reaction.

In general, odor gases generated from industrial sites such as factories or livestock sheds, when released into the atmosphere as they are, not only cause air pollution, but also seriously harm the health of residents, and furthermore, cause disputes such as civil complaints.

A deodorizer is used for the treatment of such odor gas. In general, a reaction part for deodorizing treatment is provided while the odor gas passes, and by spraying a cleaning liquid containing a chemical to the reaction part, it is reacted with the odor gas. It is possible to allow deodorization to occur.

As a technology related to a conventional deodorizer, "Scum and sediment removal device for a dust collector deodorizer" of Korean Patent No. 10-2157572 has been proposed, which is provided to collect the cleaning liquid that has passed through the reaction part in the dust collector and deodorizer, and A primary storage tank provided with a primary sediment discharge unit for discharging the sediment; A secondary storage tank provided with a scum discharge part for discharging an upper scum and a second sediment discharge part for discharging a lower sediment; A scum wall flow guide installed between the primary storage tank and the secondary storage tank to guide the scum to overflow from the primary storage tank to the secondary storage tank, and to block re-inflow of the overflowed scum into the primary storage tank; A chemical liquid mixing tank in which the cleaning liquid is introduced and stored from the secondary storage tank through an inlet, a chemical liquid supply line for adding a chemical liquid to the cleaning liquid is installed, and an agitator for stirring the chemical liquid with the cleaning liquid is installed; And a cleaning solution supplying unit supplying a cleaning solution from the chemical solution mixing tank to a cleaning solution spraying unit for spraying the cleaning solution to the reaction unit in the dust collecting and deodorizing unit, wherein the chemical solution mixing tank is connected to the secondary storage tank through an inflow path, A water level control unit for adjusting the level of the cleaning liquid is provided, an excess amount discharge line is provided for discharging the excess cleaning liquid to the outside from the water level controlled by the water level control unit, and a meter for measuring the water quality of the cleaning liquid is installed, The inlet passage comprises a vertical passage partitioned by two partition walls vertically between the secondary storage tank and the chemical solution mixing tank, and the secondary storage tank through an opening formed under the partition wall on the side of the secondary storage tank.

Meanwhile, in a conventional deodorizer, in order to remove malodorous substances, an OPR meter (Oxidation and Reduction Potential meter) is used to control the supply amount of a chemical, for example, sodium hypochlorite to the cleaning solution. The proper ORP setting value depends on the inflow concentration of odor substances. In general, when the inflow odor concentration is high, the ORP setting value should be set high, and when the odor concentration is low, the ORP setting value should be set low. Since it is common for the odor concentration to fluctuate significantly throughout the day, when operating with a specific ORP setting value, the odor treatment efficiency is very deteriorated during the period of inflow of high concentration odor, and the use of chemicals is unnecessary during the period of inflow of low concentration odor. There is a downside to being increased. However, it has a problem that it is very difficult in reality to properly adjust the ORP setting value by checking the inflow odor concentration in real time.

In order to solve the problems of the prior art as described above, the present invention sets the basic setting value of the oxidation-reduction potential difference with respect to the cleaning liquid before reaction with the odor gas for determining the condition of supplying the chemical to the cleaning liquid. By varying according to the oxidation-reduction potential difference of, the control necessary for proper treatment according to the odor concentration of the inflowing odor gas is achieved, thereby increasing the treatment efficiency of the high concentration odor gas and reducing unnecessary chemical consumption during the treatment of the low concentration odor gas. It aims to increase economic efficiency by reducing it.

Referring to FIG. 1, a variable setting type deodorizer 100 according to an embodiment of the present invention includes a main body 110, a cleaning liquid spraying part 120, a medicine supplying part 130, a water collecting part 140, and a first ORP. It may include a meta (Oxidation and Reduction Potential meter) 150, a second ORP meta 160, and a control unit 170.

The main body 110 has an inlet 111 of a malodorous gas and an outlet 112 of a processing gas provided at the side and upper portions, respectively, and a reaction unit for deodorizing the malodorous gas inside between the inlet 111 and the outlet 112 ( 113) is installed, and a water storage unit 115 for storing the cleaning liquid that has passed through the reaction unit 113 is provided below.

In the main body 110, a filling filter 113a may be installed in the inner reaction part 113 to improve the reaction efficiency between the odor gas and the cleaning liquid, and a demister ( 114) can be installed. The demister 114 removes moisture contained in the process gas to be discharged through the discharge port 112.

The cleaning liquid spraying unit 120 sprays the cleaning liquid of the water storage unit 115 onto the reaction unit 113. The cleaning liquid spraying unit 120 is positioned above the reaction unit 113 in the main body 110 with the cleaning liquid supplied through the injection line 122 from the reservoir 115 by the pumping force of the first pump 121 It can be evenly sprayed to the lower reaction unit 113 through the spray nozzle 123.

The second ORP meter 160 measures the redox potential difference of the cleaning liquid collected in the water collecting unit 140, for example, the oxidation-reduction potential difference with respect to the cleaning liquid collected in the water collecting container 141. After the reaction with, measure the redox potential difference for the cleaning solution.

The control unit 170 compares the oxidation-reduction potential difference measured by the first ORP meter 150 with a control reference setting value or a control reference setting range, and Control the supply of, and when the redox potential difference measured by the second ORP meter 160 exceeds the change reference setting value or the change reference setting range, the control reference setting value or the control reference setting range is reset to a smaller value. And, when the redox potential difference measured by the second ORP meter 160 is less than the change reference setting value or the change reference setting range, the control reference setting value or the control reference setting range is reset to a larger value, and then the first ORP The supply of the drug to the cleaning solution by the drug supply unit 130 is controlled by comparing the redox potential difference measured by the meta 150 with a reset control reference setting value or a control reference setting range.

The control unit 170, for example, when the redox potential difference measured by the first ORP meter 150 is less than the control reference setting value or the control reference setting range, the chemical tank by driving the second pump 133 of the drug supply unit 130 When the chemical in 131 is supplied to the cleaning solution of the storage unit 115, and the redox potential difference measured by the first ORP meter 150 exceeds the control reference setting value or the control reference setting range, the second pump ( By stopping 133), the supply of chemicals to the cleaning liquid of the water storage unit 115 is stopped.

2 is a flowchart showing a variable setting type deodorization method according to the first embodiment of the present invention. The variable setting type deodorization method according to the first embodiment of the present invention uses the variable setting type deodorizer 100 according to an embodiment of the present invention using a control reference setting value and a change reference setting value, and overlapping descriptions Will be omitted. In addition, in the variable setting type deodorization method according to the first embodiment of the present invention, it goes without saying that the control operation may be performed by the control unit 170.

Referring to FIG. 2, first, before being injected into the reaction part 113 of the deodorizer 100, the difference between the oxidation-reduction potential of the cleaning liquid before the reaction with the malodorous gas and the control reference set value is compared, and the chemical for the cleaning liquid before the reaction Control the supply of (S11, S12, S13). That is, before spraying to the reaction part 113, the oxidation-reduction potential difference was measured with the first ORP meter 150 with respect to the cleaning liquid in the reservoir 115 (S11), and the oxidation-reduction measured with the first ORP meter 150 When the potential difference is less than the control reference set value, the chemical in the chemical tank 131, for example, an oxidizing agent such as sodium hypochlorite or hydrogen peroxide, is supplied to the cleaning liquid in the reservoir 115 by the chemical supply unit 130. In addition, when the redox potential difference measured by the first ORP meter 150 exceeds the control reference set value, the supply of the drug to the reservoir 115 by the drug supply unit 130 is stopped (S13).

Then, after passing through the reaction unit 113 and reacting with the odor gas, the oxidation-reduction potential difference of the cleaning solution is measured with the second ORP meter 160, and it is determined whether the measured oxidation-reduction potential difference exceeds the change reference set value. (S14).

Then, if the oxidation-reduction potential difference of the cleaning solution after reaction with the odor gas exceeds the change reference setting value, the control reference setting value is reset to a smaller value (S15), and the oxidation-reduction potential difference of the cleaning solution after the reaction with the odor gas If is less than the change reference setting value, the control reference setting value is reset to a larger value (S16).

When a subsequent operation is required (S17), that is, when the deodorizer 100 is continuously used, the oxidation-reduction potential difference of the cleaning liquid before reaction with odor gas and the reset control reference setting value are compared, and the cleaning liquid before reaction Control the supply of drugs to the drug. This step is the same as the steps (S11, S12, S13) of controlling the supply of chemicals to the cleaning liquid before the reaction, except for using the control reference set value resetting the control reference set value.

The determining step (S14) and the step of resetting (S15, S16) are repeatedly performed while a continuous operation is required (S17), and according to the difference in oxidation-reduction potential of the cleaning liquid after the reaction with the malodorous gas, the control reference set value Can be reset.

In the resetting steps (S15, S16), a plurality of step-by-step set values with intervals within the range of the required minimum and maximum values of the oxidation-reduction potential difference for the pre-reaction cleaning solution are pre-determined, and the control reference set value is reset to a smaller value. In this case, the setting value of the neighboring lower stage is selected, and when resetting the control reference setting value to a larger value, the setting value of the neighboring upper stage is selected, but the reset control reference setting value is the minimum value and the maximum value. It can be placed in between. That is, the control reference setting value may be, for example, 200 mV, which may be an initial operation setting value. This can be set step by step within the range of the minimum value of 100mV to the maximum value of 400mV, 100mV, 150mV, 200mV, 250mV, 300mV, 350mV, 400mV. In addition, the change reference setting value can be set to, for example, 100 mV. These set values are exemplary and may be variously determined in consideration of the components of the odor gas, the type of chemicals, and the treatment capacity.

3 is a flowchart illustrating a variable setting type deodorization method according to a second embodiment of the present invention. The variable setting type deodorization method according to the second embodiment of the present invention uses the variable setting type deodorizer 100 according to an embodiment of the present invention using a control reference setting range and a change reference setting range, and overlapping descriptions Will be omitted. In addition, in the variable setting type deodorization method according to the second embodiment of the present invention, it goes without saying that the control operation may be performed by the control unit 170. Here, the control reference setting range may mean between a control reference setting lower limit value and a control reference setting upper limit value. The change criterion setting range may mean between the change criterion setting lower limit value and the change criterion setting upper limit value.

Referring to FIG. 3, first, before being injected into the reaction part 113 of the deodorizer 100, the difference in the oxidation-reduction potential of the cleaning liquid before the reaction with the malodorous gas and the control standard setting range is compared, and the chemical for the cleaning liquid before the reaction Control the supply of (S21 to S26). That is, before being injected into the reaction part 113, the redox potential difference measured by the first ORP meter 150 is measured for the cleaning liquid in the reservoir 115, and the oxidation-reduction potential difference measured by the first ORP meter 150 is controlled. If it is less than the reference setting lower limit (S21), unless it is stopped because it does not continue to operate (S22, S23), the chemicals of the chemical tank 131, such as sodium hypochlorite or hydrogen peroxide, are reduced by the chemical supply unit 130. It is supplied to the cleaning liquid in the water part 115 (S24). In addition, when the redox potential difference measured by the first ORP meter 150 exceeds the upper limit value set by the control standard (S25), the supply of drugs to the reservoir 115 by the drug supply unit 130 is stopped (S26), Unless it stops because it does not continue to operate (S27, S28), the subsequent operation is performed.

Subsequent operations pass through the reaction unit 113 and measure the oxidation-reduction potential difference of the cleaning solution after the reaction with the odor gas with the second ORP meter 160, and determine whether the measured oxidation-reduction potential difference exceeds the upper limit of the change criterion setting. Do (S34).

Then, if the oxidation-reduction potential difference of the cleaning solution after the reaction with the odor gas exceeds the upper limit of the change standard setting, the control reference setting range is reset to a smaller value within the minimum value range (S37) through a reduction of the variable (S36). And (S38), when the oxidation-reduction potential difference of the cleaning solution after reaction with the odor gas is less than the lower limit of the change standard setting (S29), increase the control reference setting range within the maximum value range (S32) through the increase of the variable (S31). Reset to the value (S33). At this time, after changing the control reference setting range, a duration is set in order to have a certain amount of stabilization time, so that the control reference setting range is not changed before the duration elapses (S30, S35).

Here, in order to set a constant value, for example, the number of control reference setting range step divisions (N) of the first ORP meta 150 may be set to 3, the control reference setting lower limit value is 100 mV, and the control reference setting upper limit value is 400 mV. It can be set, and the lower limit for setting the change criterion can be set at 100mV, the upper limit for setting the change criterion can be set at 200mV, and the duration can be set at 5 minutes.

In addition, for setting the variable value, the initial value of the variable i can be set to 1, and the lower limit for setting the control standard and the upper limit for setting the control standard for the variable value are shown in Table 1 below.

ｉ Control standard setting lower limit value (mV) Control standard setting upper limit value (mV) One 100 200 2 200 300 3 300 400

When continuous operation is required after that, that is, when the deodorizer 100 is continuously used, the difference in the oxidation-reduction potential difference of the cleaning liquid before reaction with odor gas and the reset control standard setting range is compared, and the chemical for the cleaning liquid before reaction Control the supply of

The determining and resetting may be performed repeatedly while a continuous operation is required, so that the control reference set value may be reset according to the difference in the oxidation-reduction potential of the cleaning liquid after the reaction with the malodorous gas.

The step of resetting is to pre-determine a number of step-by-step set values with intervals within the range of the required minimum and maximum values of the redox potential difference for the cleaning solution before the reaction, and when resetting the control reference setting range to a smaller value, the neighboring bottom Select the setting range of the stage, and when resetting the control reference setting range to a larger value, select the setting range of the neighboring upper stage, but make sure that the reset control reference setting range is located between the minimum and maximum values. I can.
