Description

Renewable toilet adsorption deodorization device

technical field

The invention relates to a device in the technical field of daily necessities, in particular to a regenerative toilet adsorption deodorization device.

Background technique

In large shopping malls, supermarkets, railway stations, bus stations, large exhibition halls and other public places with a large flow of people, public toilets often have very serious odors. At the same time, public toilets generally adopt mechanical ventilation, which directly discharges the odor of the toilet through the air outlet, which also has an impact on the outdoor environment. There are also public restrooms that use odor coverage, that is, using solid flavoring agents to emit certain fragrances in public restrooms to cover the odor, but the mixture of fragrance and odor still makes the bathroom smell even worse.

After searching the literature of the prior art, it is found that the Chinese utility model patent name is: air deodorization and sterilization device for public toilets, and the application number is: 200720190181.4. This patent discloses a deodorization and sterilization device for public toilets. A liquid storage tank with deodorizing and bactericidal agents is installed in the public toilet, and a series of operations such as a lift pump, a low water level protector, a high water level protector, an atomizer box and a fan in the liquid storage tank are used to achieve deodorization. The purpose of odor sterilization, but considering that the deodorant bactericide itself has a certain impact on people, and the device is complicated and the cost is high, the problem of toilet ventilation and exhaust is not considered.

Contents of the invention

The present invention aims at the above-mentioned deficiencies in the prior art, and provides a regenerative toilet adsorption deodorization device. The deodorization device for treating the polluted gas in public toilets can be used to place indoors by adding a fan to deodorize the indoor air. Circular deodorization can also be used to connect with the exhaust outlet to remove the polluted gas in the exhaust air and avoid polluting the surrounding environment of public toilets.

The present invention is achieved through the following technical proposals. The present invention includes: a housing, a first-stage filter element, a second-stage filter element, and two layers of slow-flow filter material, wherein: the first layer of slow-flow filter material, the first-stage filter The core, the second layer of slow-flow filter material and the second-stage filter core are filled in the housing in sequence.

The housing is a hollow cuboid structure, and the two ends of the housing are respectively provided with an air inlet, an air outlet and a compartment, the air inlet and the air outlet are smaller than the cross section of the middle part of the housing, and several compartments are respectively vertically arranged inside the housing, The air inlet is connected with the fan or the exhaust duct, and the air outlet is connected with the diffuser or the exhaust duct.

If the deodorizing device is directly used for the deodorization of the exhaust air, the air inlet and the air outlet are connected to the exhaust duct, and the exhaust air enters through the air inlet and is discharged from the air outlet; if the deodorizing device is directly placed in the bathroom as For indoor circulating air deodorization, the air inlet is connected to the fan, and the air outlet is connected to the diffuser.

The first stage filter element is activated carbon sponge, the carbon content of the activated carbon sponge is 50%, and the outer surface of the activated carbon sponge is provided with shaped gauze, and the first stage filter element is aimed at the adsorption of H ₂ S gas.

The second-stage filter element includes: 80% mass ratio of phosphoric acid activated carbon and 20% zeolite particles, and its outer surface is provided with a shaped gauze; carbon sponge.

The first layer of slow-flow filter material is porous activated carbon sponge.

The second layer of slow-flow filter material is porous activated carbon sponge.

The deodorizing device of the present invention is placed in a public toilet, and can be used as a deodorizing device for indoor circulating air, connected with a fan, to absorb and deodorize H ₂ S and NH ₃ in the toilet room, and can also be used as a deodorizing device for exhausting air in the toilet. The odor device is connected after the exhaust fan and before the exhaust outlet to deodorize the exhaust air. According to the actual experimental test, the two kinds of filter elements plus slow flow filter material have the best adsorption effect on H ₂ S and NH ₃ , and can absorb more than 90% of H ₂ S and more than 70% of NH ₃ entering the deodorization device. Meet the need for deodorization of public toilets. The deodorizing device of the present invention is designed in different sizes for public toilets of different sizes, and the design effective use time is 3 months. Then open the detachable plate, take out the filter element, heat and desorb it, and then use it again to replace the cheap slow-flow filter material.
