1 is a cross-sectional view of the malodor deodorizer according to the present invention.

Hereinafter, the structure of the deodorizer according to the present invention will be described in detail with reference to FIG.

First, the deodorizer of Figure 1 is used to be mounted on the outside of the manure vacuum tank lorry vehicle. The deodorizer of the present invention has a structure filled with impingement plates and granular activated carbon layers in the deodorization tank 20. In more detail, at the bottom, a separation mechanism 4 for separating gaseous odors and high-liquid foreign substances, ie, manure solids, which are included in the odor gas is first installed, and the separation mechanism 4 includes a secondary collision plate ( 4a), the lower discharge port 4b, the oil inclined plate 4c, and the waste discharge valve 4d for discharging the solid liquid dirt.

Further, outside the deodorization tank 20, a malodorous gas induction pipe 1 for guiding exhaust air (odor gas) discharged from the manure vacuum tank lorry vehicle to the deodorizer of the present invention is installed, and the exhaust air induction pipe 1 ) Is connected to one side wall surface of the deodorization tank 20 via the safety valve (2). The other side wall surface of the deodorizing tank 20, that is, the side wall surface on the opposite side of the attached portion that is the exhaust air induction pipe 1, is automatically cleaned in the manure tank when the manure is discharged from the manure vacuum tank lorry to the outside. The check valve 11 for supplying air is provided.

A primary collision plate 3 is provided above the separation tank 4, and a first perforated stainless steel net 5 is provided on an upper portion of the primary collision plate 3, and the first perforated stainless steel is provided. The fibrous carbon filter element 6 is provided in the upper part of the web 5. In addition, a first granular activated carbon layer 7 is provided above the fibrous carbon filter 6, and a second perforated stainless steel network 8 is provided above the first granular activated carbon layer 7. The second granular activated carbon layer 9 is provided on the second perforated stainless steel net 8. The lid 11 of the deodorizing tank 2C is attached to the upper side of the second granular activated carbon 9. In addition, a deodorization gas outlet 10 for discharging the deodorizing gas from which the odor is deodorized is formed on the upper portion of the deodorization tank 20.

The odor deodorization mechanism using the deodorizer having the structure as shown in FIG. 1 is as follows. First, the exhaust air discharged through the gas outlet of the manure vacuum tank lorry vehicle is passed into the deodorizer of the present invention through a odor gas induction pipe 1 and a safety valve 2 having an inner diameter of 50 mm installed under the deodorizer. Inflow. The safety valve (2) is a smooth manure collection operation without straining the vacuum tank in the event of an emergency in which the gas is not discharged smoothly from the deodorizer, the pressure rises beyond the normal pressure of about -1kg / ㎠ It is a safety device that discharges gas as much as possible.

The malodorous gas introduced through the malodorous gas induction tube 1 contains a small amount of oil, manure filth, water, and the like.

Next, the malodorous gas introduced into the deodorizing tank 20 firstly moves upward, and then impinges on the primary impact plate 3 installed in the deodorizing tank 20 and then moves downward. The primary collision plate allows odor gas in a turbulent flow state to be smoothly transferred to the lower discharge port 4b and the secondary collision plate 4a, and also lowers the velocity of foreign matter so as to maximize laminar flow in activated carbon. It plays a part in blocking the flow to induce laminar flow. The primary collision plate 3 is installed in the deodorization tank 20 to protrude into the pipe at the 50 mm shear point of the check valve. The protruding size of the primary collision plate 3 is about 15 mm and is attached to the pipe.

Next, the exhaust air which has hit the primary collision plate 3 and moved downward hits the secondary collision plate 4a and is separated into a gaseous odor and a foreign substance in a liquid or solid phase. It is converted to a flow and foreign matter falls through the lower outlet 4b to the oil swash plate 4c on the lower side. The oil inclined plate 4c is provided to have an inclination angle of about 15 ° so as to smoothly collect oil and solid liquids, that is, dirt, into the discharge port 4d. If dirt is seen to some extent in the separating mechanism 4, it is discharged out through the outlet 4d.

On the other hand, the odor hitting the secondary impingement plate (4a) is turned upward flows through the first perforated stainless steel mesh (5) to pass through the primary deodorizing fibrous activated carbon (fibrous activated carbon). The first perforated stainless steel mesh 5 is made of stainless steel, and is made of about 70-80 small holes having a diameter of 5 mm. In addition, the fibrous carbon filter 6 is a nonwoven carbon filter laid on the first perforated stainless steel network 5 to perform a primary deodorizing function.

The malodorous gas deodorized first while passing through the fibrous carbon filter 6 is deodorized secondarily through the first granular activated carbon layer 7 (Granular Activated Carbon). The first granular activated carbon layer 7 has a thickness of about 150 mm and is mainly deodorized from the first granular activated carbon layer 7.

Next, the malodorous gas which is mainly deodorized in the first granular activated carbon layer 7 continues through the second perforated stainless steel network 8 and passes through the second granular activated carbon layer 9 having a thickness of about 50 mm, thereby finally deodorizing. Lose. The second perforated stainless steel net 8 serves to prevent tangling and channeling of activated carbon by punching about 120 small holes of about 3 mm into a stainless steel plate.

The gas passing through the second granular activated carbon layer 9 is a gas from which most of the odor is deodorized and is discharged into the air through the discharge port 10.

During the cleaning process, the manure flows into the vacuum tank, increasing the pressure, and briefly describing the process in which the odor gas in the tank lorry is discharged through the deodorizer.

Odor gas (including oil and dirt) → Safety valve → Primary collision plate → Lower outlet and secondary collision plate → Primary perforated stainless steel network → Fibrous carbon filter (1st deodorization) → Activated carbon (2nd deodorization) → 2nd perforation Stainless steel → Activated carbon (third deodorization) → Outlet (air exhaust)

On the other hand, when the manure transfer (discharge) work out from the manure tank lorry, the air supply to the tank lorry is mainly supplied with clean air outside through the check valve (11).

Anticipated problems associated with using the adsorption type deodorizer as described above include oil and manure (including water) leaking from the tank lorry to some deodorizers to block the pores of activated carbon and to reduce adsorption or channeling. Can be mentioned. In the present invention, in order to prevent this, by installing a collision plate to lower the flow rate of the gas and change the direction of the gas and foreign matter to the bottom while the gas changes the flow in the upward direction, but the foreign matter does not change the direction as it is discharged to the bottom. The top cover was opened so that the granular activated carbon and the fibrous activated carbon filter inside could be replaced. In addition, the deodorizer material is made of stainless steel so that it can withstand almost manure odor almost permanently.

The adsorption type activated carbon deodorizer of the present invention was tested in a sewage sludge cleaning vehicle with a capacity of 5 kW at the sewage treatment facility (2000 kW / day) of the Seonam sewage treatment facility (formerly Gayang Sewage Treatment Office) in Gangok-gu, Seoul. As a result of testing by sensory method, six people who participated in the test showed that it was difficult to detect slight odor or odor itself, and it was confirmed to show the same effect as liquid deodorization by conventional chemicals (ClO ₂ ). It was.

The deodorization system according to the present invention uses a physical treatment method of attaching and concentrating solute dispersions or colloidal substances in gases, vapors, and liquids to the surface of solid materials with physical and chemical affinity, and mainly using activated carbon as a method of using solid materials. However, since the activated carbon adsorption method does not use water or chemicals, there is no need for a total operation management operation, and there is an economical advantage because the device is relatively simple and recycled carbon can be used.

The manure cleaning vehicle uses a high-pressure vacuum suction vehicle, so it is easy to operate because it is installed in the vehicle and uses power like a compressor that sucks manure without the need for a gas transfer device to an activated carbon deodorizer such as an inflow fan.
