detailed description

Below in conjunction with accompanying drawing and embodiment of description, the specific embodiment of the utility model is described in further detail:

With reference to Fig. 1 and shown in Fig. 2, the main structure of the present utility model is the deodorizing box buried below the ground surface, and above the main structure, cement grass-planting bricks 17 are laid for greening or use as a parking lot. Two porous supporting plates 1 are fixed inside the deodorizing box, and the two porous supporting plates 1 divide the internal space of the deodorizing box into an upper space 2, a middle space 3 and a lower space 4, and the upper space 2 is a soil layer, filled with There is loose soil, the middle space 3 is a filter material layer filled with porous filter material, and the lower space 4 is a water collection layer, which is a water collection tank 5 for storing rainwater; the water collection tank 5 is connected with the water inlet pipe 6 at its side The drainage ditch on the surface or a special rainwater collection device is used to collect the rainwater on the surface into the water collection tank 5 at the bottom of the deodorization box for storage. Pipeline connection, an air pump 10 is installed on the air intake pipe 7, which is used to send industrial waste gas into the water collection tank 5, and the part of the air intake pipe 7 inserted into the water collection tank 5 is provided with an aeration hole, and the industrial waste gas passes through the aeration hole The inner spray is fully contacted with the rainwater in the water collection tank 5; in addition, a water spray pipe 8 is also connected between the soil layer and the water collection layer, and the part of the water spray pipe 8 extending to the soil layer is provided with a water spray port. A pump 9 is installed on the pipeline 8, which is used to transport the rainwater in the water collection tank 5 into the soil layer and spray it out through the water nozzle to spray the loose soil in the soil layer; since the porous supporting plate 1 is porous Therefore, the industrial waste gas sprayed from the aeration holes and fully mixed with rainwater will diffuse upward through the porous support plate 1 and enter the filter material layer and soil layer in turn, so that the industrial waste gas can be decomposed in the filter material layer and soil layer and filter. And the rainwater ejected from the spout enters the soil layer and the filter material layer successively to keep the soil and the porous filter material moist and get back to the water collection tank 5, forming a water cycle in the deodorizing tank, which is convenient for the recycling of rainwater.

It should be noted that the loose soil in the soil layer is cultivated with special microorganisms that can absorb and degrade industrial waste gas after artificial domestication, and can catabolize the organic components in industrial waste gas, and the inorganic substances produced after catabolism can be used for the pollution on the surface. Vegetation grows and reproduces; the porous filter material in the filter material layer is made of a combination of various composite materials, which has the function of absorbing odor, and deodorizing microorganisms are cultivated in the porous filter material, and the microbial film formed by the deodorizing microorganisms is attached to the porous filter material. On the filter material, the organic pollutants in the industrial waste gas enter the deodorizing microorganisms and are decomposed into harmless compounds.

In addition, vertical columns 16 are arranged inside the whole deodorization box to reinforce the frame structure of the deodorization box to prevent collapse caused by excessive pressure.

Since the water collecting tank 5 is mainly supplied with rainwater through the water inlet pipe, after the excessive rainwater enters the water collecting tank 5 in the season with large rainfall, it will spread upwards and enter the filter material layer or even the soil layer, that is, the excessive rainwater entering the deodorization tank will easily cause the soil layer And the filter material layer is in a flooded state, which affects the growth of microorganisms, and it is also easy to cause excessive pressure in the deodorization box. Therefore, a water storage tank 12 is installed outside the deodorizing tank, and the water storage tank 12 is communicated with the water collection tank 5 through the water inlet pipeline 6. At the same time, a flow control valve 11 is installed on the water inlet pipeline 6 to control the flow into the water collection tank 5. In the season with high rainfall, the excess rainwater will be stored in the water storage tank 12 first, and the amount of rainwater entering the water collection tank 5 will be adjusted by controlling the flow control valve 11, so as to ensure the rainwater circulation in the deodorization tank .

In addition, since the surface rainwater is often mixed with a large amount of silt or sand and other sundries, a filter 14 is also installed in the water storage tank 12 to filter the rainwater to prevent silt and sand from blocking the water inlet pipe 6. A removable cover plate 13 is installed on the top of the water storage tank 12 to facilitate regular cleaning of silt and gravel in the water storage tank 12 to ensure the water storage capacity of the water storage tank 12 and the filtering ability to rainwater.

A side excavation of the deodorizing box is constructed with an overhaul channel 15, so that maintenance personnel enter the ground below the surface to overhaul and maintain the deodorizing box.

The porous support plate 1 is fixed inside the deodorization box, and its porous structure allows water and gas to enter and exit freely. At the same time, the space between the two porous support plates 1 is used to form a filter material layer, and the porous filter material in the filter material layer Usually it needs to be replaced regularly to ensure the treatment capacity of industrial waste gas. Therefore, a hatch door is installed on the side wall of the deodorization box corresponding to the filter material layer to facilitate regular replacement of the porous filter material. The hatch door is opened in the direction of the deodorization box. One side of the study passage.

The utility model adopts a geographical landfill structure below the ground, which greatly reduces the occupied area of the industrial waste gas treatment device, saves a large amount of surface space, and makes full use of the relatively constant temperature of the soil, which is beneficial to the reproduction of microorganisms and is beneficial to industrial waste gas. The treatment effect is good. The whole deodorization box can adopt a concrete structure, which not only saves costs, but also is reliable and easy to operate. The use of microorganisms to absorb industrial waste gas not only has a good treatment effect, but also does not produce secondary pollution, and the operating cost is low; The internal space of the smelly box is divided into an upper space 2, a middle space 3 and a lower space 4 by two porous support plates 1, and a large amount of porous filter materials are filled in the middle space 3. The supporting effect can also slow down the flow velocity of industrial waste gas; the porous filter material can not only provide attachment places for microorganisms, but also effectively absorb and deodorize industrial waste gas, and at the same time slow down the flow velocity of industrial waste gas, making the porous filter material The microbes on the material can contact the industrial waste gas more fully, and the prolongation of the contact time further improves the treatment effect of the industrial waste gas; in addition, by collecting the surface rainwater and transporting the rainwater to the water collection tank 5 through the water inlet pipe 6, The rainwater entering the water collection tank 5 is fully in contact with the industrial waste gas entering the water collection tank 5 through the air intake pipe 7 to initially moisten the industrial waste gas; the rainwater in the water collection tank 5 is pumped to the soil through the water spray pipe 8 layer to keep the soil and porous filter material moist, and improve the treatment effect of industrial waste gas; the industrial waste gas in the water collection tank 5 fully contacted with rainwater diffuses into the filter material layer and soil layer from bottom to top, and interacts with microorganisms Make full contact and use the metabolism of microorganisms to degrade the organic pollutants in the industrial waste gas; in order to facilitate the management and maintenance of the deodorization box, an inspection channel 15 is specially set up, and it is opened on the side of the deodorization box near the inspection channel 15 There is a hatch for replacing the porous filter material in the filter material layer to ensure the working efficiency of the porous filter material; in order to control the flow of rainwater entering the deodorization box and avoid excessive pressure in the deodorization box, especially in the A water storage tank 12 is arranged outside the deodorization box, and the water storage tank 12 is connected to the water collection tank 5 through the water inlet pipe 6, and a flow control valve 11 is installed on the water inlet pipe 6 to precisely control the amount of rainwater entering the deodorization box , to ensure the operation of its internal water cycle.
