The present invention relates to a double odor deodorizing device, and more particularly to a double odor deodorizing device that can deodorize the odor that can not be decomposed in the deodorizing device by the existing microorganisms by the hydroxyl group.

Existing sewage and wastewater treatment devices are treated with various types of deodorizers such as adsorption, chemical treatment, and biodegradation methods. However, most of the deodorization methods are installed site, initial investment cost, and maintenance. Due to various problems such as costs, not only are they not getting the same expectations as the investment cost, but also a lot of human and material support is required because of continuous management and cost to maintain stable operation.

Looking at the deodorizing device by the bio-filter biodegradation method commonly used among the existing deodorizing method,

The odor stays and microorganisms are planted by allowing the odor collected in the deodorization tower configured to maintain humidity by spraying the feed water at regular intervals or continuously to form a carrier in the middle part so that the odor stays in the lower space through the odor supply pipe. As the odor is decomposed by the microorganisms in contact with the carrier, it is raised to remove the odor.

The biofilter, which is a deodorizing device using such microorganisms, has a problem of changing the deodorizing function of microorganisms due to temperature change, that is, the activity of microorganisms is considerably low in winter when the temperature is low, so that normal odor decomposition cannot be performed. Since it is discharged to the outside there was a problem such as causing environmental pollution.

In addition, in order to cope with a high concentration of odor that is more than the odor treatment capacity of the deodorizer in order to cope with this situation is not operating a system suitable for the concentration is operating inefficient.

The present invention has been proposed in order to solve the above-mentioned problems, and by providing a second deodorizing function to the existing deodorizing device to be able to freely selectively perform the first and second treatments according to the change in the odor concentration, winter season The purpose of the present invention is to provide a double odor deodorizing device that can compensate for the efficiency caused by the low propagation of microorganisms.

The characteristic configuration of the present invention for achieving the above object is as follows.

A deodorizing apparatus for deodorizing the odor flowing through the odor exhaust line through the biofilter, the nozzle is provided so that the hydroxyl soluble water supplied to the rear of the odor exhaust line is sprayed to contact the hydroxyl soluble water to the odor exhausted And a hydroxyl group dissolved water supply device for supplying hydroxyl group dissolved water to the dissolved water contacting tank.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows the configuration of the present invention,

The malodorous biofilter 30 is connected to the odor exhaust line 10 through which the odor is forcibly introduced by the blowing fan 20 and the like through the connection lines 11 and 11 ′ which enter and exit the biofilter 30. It is deodorized as it passes through, and has on / off valves V1, V2, and V3 in the connection lines 11 and 11 'and the odor exhaust line 10 so as to selectively control them.

The rear of the odor exhaust line 10 is provided with a nozzle 41 so as to finely spray the hydroxyl dissolved water supplied up and down is provided with a dissolved water contact tank 40 to contact the hydroxyl dissolved water to the odor exhausted.

A hydroxyl group dissolved water supply device 50 for circulating and supplying hydroxyl group dissolved water to the dissolved water contact tank 40 is provided.

The hydroxyl group dissolved water supply device 50 includes a hydroxyl group dissolved water generator 51 which obtains and supplies a hydroxyl group (OH) dissolved water by reaction of water supply and ozone supplied from the outside;

Dissolved water storage for storing the dissolved hydroxyl water supplied from the hydroxyl dissolved water generator 51 to be circulated through the dissolved water supply and drain line (54, 54 ') to the dissolved water contact tank 40 by the pump 52 The tank 53 is configured.

The pH sensor 55 is provided in the dissolved water storage tank 53 to be drained to the outside through the drain line 56 to be filled with a new hydroxyl dissolved water.

The hydroxyl group is known as a harmless natural substance that is involved in the deodorization, discoloration, sterilization, and disinfection of almost all pollutants, and exhibits a powerful effect that can be chemically decomposed and removed, as shown in FIG. 2. The hydroxyl group (OH) generated by the reaction of water and ozone has a reaction in which water and oxygen are reduced in contact with the malodor.

As for the biofilter 30, the structure thereof is described in the prior art.

Referring to the present invention configured in this way as described in detail as follows.

First, when the odor introduced through the odor exhaust line 10 by the blower fan 20 is exhausted through the biofilter 20, when the odor is introduced while the valve V1 of the odor exhaust line 10 is locked. It flows into the lower part of the biofilter 30 through the line 11 and is raised while going through the process of decomposing odor by microorganisms in contact with the carrier where the microorganisms are planted as the odor stays. The gas is exhausted to the odor exhaust line 10 again, and the gas that has undergone the deodorization process through the biofilter 30 is discharged to the outside while passing through the dissolved water contact tank 40 provided at the rear of the odor exhaust line 10. do.

The hydroxyl dissolved water supplied by the hydroxyl dissolved water generator 50 to the dissolved water contacting tank 40 is supplied through the water supply line 54 and sprayed by the nozzle 41 to dissolve the hydroxyl dissolved water in the biofilter 30. In contact with the undecomposed malodorous constituents and combines with the hydroxyl group to reduce the odor by reducing the water and oxygen again, the sprayed dissolved water is again in the hydroxyl dissolved water storage tank through the drain line (54 ') Flows into (53).

This odor deodorizing action is to perform a secondary odor deodorizing function that decomposes odor by hydroxyl groups of odors not filtered by the biofilter 30 which is a primary odor deodorizing function.

The secondary deodorization function by the hydroxyl dissolved water can be selectively performed, that is, the biofilter 30 performing the primary deodorization function is difficult to perform the deodorization function or when the high concentration odor occurs over the treatment capacity. Deodorizing function can be combined.

In addition, when the biofilter 30 is not used or cannot be used, the odor may be decomposed by a contact reaction by a hydroxyl group while passing the odor without passing through the biofilter 30 to the dissolved water contacting tank 40. This may be possible in the case of low concentrations of odor, taking into account the limitations of the processing capacity.

As another example, the odor flowing into the odor exhaust line 10 may first pass through the dissolved water contact tank 40 and then be exhausted to the outside through the biofilter 30.

As described above, the present invention can perform a deodorization function or perform a deodorization function selectively according to the concentration of odor, thereby improving the efficiency of deodorization and reducing the operating cost, and deodorizing microorganisms according to seasonal changes. The reduction in efficiency of the group can be compensated for. In addition, it is possible to reduce the odor retention time of the biofilter has the effect of reducing the appearance of the facility.
