Embodiment 1

[0040] see Figure 7-8 , a method for preparing biospheres for biological deodorization, comprising the following steps:

[0041] (1) Process wood chips into wood chip masterbatch;

[0042] (2) Send the main material PP (polypropylene), sawdust masterbatch, foaming agent, and lubricant into the autoclave at a ratio of 0.75:0.12:0.06:0.07 for mixing and stirring to obtain material A;

[0043] (3) Feed material A into the extruder for extrusion drawing and pelletizing, with a particle size of 1-5mm;

[0044] (4) heating and pressurizing the particles in a foaming device to obtain disposable foamed particles;

[0045] (5) pre-compressing the primary foamed particles to implement secondary foaming, and drying the secondary foamed particles to obtain foamed particles;

[0046] (6) The foamed particles are sent into the extruder to melt and extrude the plate-shaped foam plate through the die;

[0047] (7) Then pass the foam board through the crusher, and after being crushed by t...

Embodiment 2

[0055] The same as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0056] see Figure 1-2 , the biosphere 12 is applied in the deodorization box 10, the bottom side of the deodorization box 10 is provided with an air intake pipe 17, and the deodorization box 10 located at the upper end of the air intake pipe 17 is provided with a plurality of successively stacked deodorant boxes. Smelly bed 11, the deodorizing bed 11 is a square frame, and the bottom of the deodorizing bed 11 is provided with a fixedly connected partition net 111, and the biological balls are evenly spread on the partition net 111 in the deodorizing bed.

[0057] The design of the multi-layer dividing net 111 can not only make the distribution of bioballs in the deodorization box more uniform, but also break up the air bubbles formed by the exhaust gas entering the deodorization box through the intake air, so as to increase the contact probability between the overall exhaust gas and mi...

Embodiment 3

[0074] The same as embodiment 1 is not repeated, and the difference with embodiment 1 is:

[0075] see Figure 3-6 The above-mentioned crusher includes a crusher shell 6 and a feed table 3, one side of the crusher shell 6 is provided with a feed port 69, and the crusher shell 6 at the feed port 69 is provided with a fixed connection The feeding platform 3 of the feeder, the crusher shell 6 located at the feeding port 69 is provided with a vertically distributed conveyor belt 61, the conveyor belt 61 is provided with a plurality of crushing teeth 64, and the conveyor belt 61 is equipped with There is a top plate 63, the two ends of the top plate 63 are provided with symmetrically distributed fixed rods 67, and the extended ends of the fixed rods 67 are fixedly connected with the inner wall of the crusher shell 6 at the feed port 69, and the A feed plate 4 is provided on the feed platform 3, and a discharge port 7 is provided at the bottom of the crusher shell 6.

Abstract

The invention belongs to the technical field of waste gas treatment, and particularly relates to a preparation method of biological balls for biological deodorization. The preparation method comprises: (1) processing sawdust into sawdust master batch; (2) feeding a main material PP (polypropylene), the sawdust master batch, a foaming agent and a lubricating agent into a high-pressure reaction kettle according to a ratio of 0.75:0.12:0.06:0.07, and mixing and stirring to obtain a material A; (3) feeding the material A into an extruder, and carrying out extrusion wire-drawing and granulating, wherein the particle size is 1-5 mm; (4) heating and pressurizing the particles by using a foaming device to obtain primary foaming particles; (5) pre-pressing the primary foaming particles to implementsecondary foaming, and drying the secondary foaming particles to obtain foaming micro-particles; (6) feeding the foaming micro-particles into the extruder, melting, and extruding a plate-like foam plate through a mold; and (7) making the foam plate pass through a crusher, and crushing the foam plate through the crusher to obtain the biological ball.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a preparation method of biological balls for biological deodorization. Background technique [0002] During the process of sewage treatment and garbage treatment, gaseous substances with odorous groups will be produced and escape to the surroundings, causing pollution to the surrounding environment and bringing inconvenience to people's lives. Odor gas pollution refers to all gaseous substances that stimulate the olfactory organs to cause people's unpleasantness and damage the living environment. It stimulates olfactory cells through odorous groups. Generally, the concentration is low, the composition is complex, and it is difficult to monitor and treat. As a typical environmental hazard, it has been recognized by all countries in the world, and many developed countries have studied it as a separate pollution hazard, and implemented special legislation to ...
