The invention discloses a three-dimensional composite interplanting method for interplanting poria cocos and peanuts. The three-dimensional composite interplanting method comprises the following steps: S1, soil preparation; s2, applying a composite soil conditioner and building furrows; s3, putting the poria cocos into a cellar; s4, peanut sowing; s5, field management in the symbiotic period; s6, harvesting in a staggered manner. According to the method, the poria cocos is planted underground, the peanuts are planted on the ground, after the peanuts are harvested, the ground surface is covered with peanut straw, the poria cocos is shaded, the physical properties of soil are improved by returning the peanut straw to the field, two kinds of medicines and grains are planted in one field through poria cocos and peanut interplanting, and the land utilization rate is increased; meanwhile, the composite soil conditioner prepared by a specific method is applied, long-acting and synergistic biological stimulation is provided for the two crops, the soil permeability is improved, and special pretreatment is performed on pine sections, so that the poria cocos inoculation rate, stress resistance and yield of poria cocos strains are remarkably improved, the soil micro-ecological environment is improved, the soil permeability and enzyme activity are improved, and the yield of the poria cocos strains is increased. And double improvement of economic benefits and ecological benefits is realized.

This utility model relates to the technical field of gas recovery equipment and discloses a gas recovery device for preparing industrial sulfuric acid, comprising: a tower body with an outlet pipe at its upper end; a ring frame disposed inside the upper end of the tower body, with a first ring shell and a second ring shell rotatably mounted inside the ring frame, the first ring shell being disposed above the second ring shell, and both the first and second ring shells being filled with packing; a drive motor disposed on one side of the lower end of the second ring shell, with a drive bevel gear installed at the output end of the drive motor, a drive inner rod fixedly disposed at the lower end of the first ring shell, and a first transmission bevel gear disposed outside the lower end of the drive inner rod. This utility model, by setting a double layer of packing and rotating it in opposite directions, causes the waste gas to be subjected to shear forces and turbulence in different directions when passing through the packing layers, enhancing the gas-liquid contact and mixing effect, and improving the mass transfer efficiency.

The utility model relates to the technical field of breathing machines, in particular to a breathing machine pipeline sputum collecting device which comprises a collecting tank, a top cover is detachably installed at the top of the collecting tank, oxygen pipelines are connected to the two sides of the top of the top cover through air pipe connectors, and a negative pressure connector is arranged at the top of one side of the collecting tank. A drain outlet is formed in the bottom of the other side of the collecting tank, a detachable water accumulating cup is connected to the bottom of the collecting tank, one oxygen pipeline is connected with a breathing opening of a patient, the other oxygen pipeline is used for being connected with a breathing machine pipeline, negative pressure equipment is externally connected through the negative pressure connector, and sputum sprayed into the corresponding oxygen pipeline by the patient is sucked into the collecting tank. According to the sputum collecting device for the breathing machine pipeline, the oxygen pipeline is connected through the air pipe connector arranged at the top of the collecting tank, the sputum sprayed into the oxygen pipeline by a patient can be sucked into the collecting tank in time in cooperation with external negative pressure equipment, pollution of the sputum to the breathing machine pipeline is effectively avoided, and cleanliness and smoothness of the pipeline are kept.
