Description

A kind of biological deodorization device suitable for high dust and malodorous gas

technical field

The utility model relates to a biological deodorization device, in particular to a device for treating foul-smelling gas with a large dust content.

Background technique

The malodorous gas emitted by urban domestic waste landfill, garbage fermentation, sewage and sludge treatment is not only one of the main sources of air pollution, but also directly affects the life and health of surrounding residents. Therefore, the treatment of malodorous gas is becoming more and more important. more and more people's attention.

At present, the main methods of odor treatment are chemical washing method, physical adsorption method, biological method and so on. The chemical washing method has high treatment efficiency, but has the disadvantages of large consumption of chemicals, high operating costs, and serious secondary pollution. The physical adsorption method can treat multi-component malodorous gases, but because the adsorbent needs to be replaced regularly after adsorption and saturation, the operating cost is high, so it is only suitable for low-concentration and small-scale malodorous gases. The biological deodorization process is mainly carried out in trickling filter towers or filter tanks, which are equipped with porous fillers. By acclimating and cultivating microorganisms with deodorizing ability, they can attach and grow on the porous fillers to form a microbial film, and use this microbial film to eliminate odor. Material degrades to an odorless substance. Because of its good treatment effect and low operating cost, it is widely used in sewage treatment plants and garbage treatment processes. However, in the actual operation process, because the malodorous gas often contains a large amount of dust particles, it is easy to cause the blockage of the biological filler, increase the resistance of the system, affect the normal operation of the deodorization tower, and even cause local anaerobic secondary pollution to cause the entire system to collapse. .

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is described further.

As shown in Figure 1, a kind of biological deodorization device suitable for highly dusty and malodorous gas described in the utility model includes dust removal and deodorization tower (1), blower fan (2), sump (3), first water pump ( 41) and the second water pump (42); the dust removal and deodorization tower (1) is provided with a deodorization layer (5), a dust removal layer (6), an air distributor (9) and a liquid collection tank (10) sequentially from top to bottom The upper part of the deodorizing layer is provided with a first sprayer (71), the middle part is provided with a packing layer suitable for the growth of microorganisms, and the bottom is provided with a packing support plate (8); the upper part of the dust removal layer is provided with a second sprayer (72) , the middle part is provided with a multi-layer conical plate; each layer of the conical plate includes a plurality of parallel-arranged “∧”-shaped strips, and gaps are left between adjacent “∧”-shaped strips ;as shown in picture 2.

The multi-layer conical plates are arranged staggered up and down; the liquid inlets of the first water pump (41) and the second water pump (42) are connected with the sump (3); the liquid outlet of the first water pump (41) is connected with the first spray The liquid inlet of the device (71) is connected, the liquid outlet of the second water pump (42) is connected with the liquid inlet of the second sprayer (72), and valves are respectively arranged on the connected pipelines to adjust the spray The amount of water; the liquid outlet of the liquid collection tank (10) at the bottom of the dedusting and deodorizing tower (1) is directly connected to the sewage treatment system; the inlet side of the fan (2) is connected to the odor source, and the outlet side of the fan (2) is connected to the dust removal The gas distributor (9) of the deodorization tower (1) is connected; the odor diffuses from bottom to top inside the dust removal and deodorization tower (1), is continuously purified, and is discharged from the gas outlet at the top of the dust and deodorization tower (1).

The specific working process is: the odor from the odor source is sent to the air distributor (9) at the bottom of the dust removal and deodorization tower (1) under the action of the blower fan. The odor is evenly distributed through the air distributor (9) and diffuses upwards into the dust removal layer (6). Particles in the air flow fall under the obstruction of the conical plates, and the gas deflects upward and passes through the gap between the conical plates; at the same time, the second water pump (42) can be turned on to draw water from the sump (3), and the valve can be adjusted to Appropriate opening degree, the water flow is evenly sprayed on the dust removal layer through the second sprinkler (72); the rising odor is in countercurrent contact with the sprayed liquid in the dust removal layer, and the dust particles in it are combined and captured by the droplets In addition, the staggered arrangement of the conical plates on the dust removal layer can guide the water flow to wash away the particles falling on the conical plates to achieve the purpose of dust removal. The odor passing through the dust removal layer not only removes the particulate matter, but also dissolves some soluble components in the odor. The odor continues to rise to the deodorization layer (5), turn on the first water pump (41) and adjust the valve on its pipeline to a suitable opening, so as to provide the necessary spray amount for the growth of microorganisms, if the odor enters the deodorization layer, the humidity If the humidity is higher and can meet the humidity requirements for microbial growth, then the first water pump can be turned off. The malodorous substances in the odor gas are discharged from the top of the tower after being degraded into odorless substances by microorganisms in the deodorizing layer.
