Problems solved by technology

[0002] Nowadays, China is promoting urbanization construction, and each community will produce a large amount of feces that need to be treated. If the organic matter, nitrogen and phosphorus in the feces are directly discharged, it will cause water pollution and emit rich ammonia, hydrogen sulfide, acid alcohols, sulfides, etc. Harmful gases with malodorous components, although the construction of the community is equipped with sewage pretreatment facilities such as septic tanks, but the post-treatment will eventually be transported to the urban sewage treatment plant for treatment
Feces are easily polluted by more heavy metals in the process of entering the urban sewage treatment plant through the sewer after simple fermentation in the septic tank, and the waste sludge produced by the sewage treatment plant cannot be used as fertilizer for plant growth due to heavy metals exceeding the standard. Can be landfilled, resulting in a lot of waste of resources

Embodiment 1

[0027] Embodiment one: see Figure 1-Figure 5 , a fertilizer making system using solar energy to dry feces, comprising a spherical reflective focusing solar device 1, a conical inner-rotating dryer 2 arranged in the middle of the spherical reflective focusing solar device 1, a dry material storage tank 3 and a grouting control system 4 The spherical reflective focusing solar device 1 includes a solar reflector support 101 in a spherical structure, a spherical solar reflector 102 arranged on the solar reflector support 101 for matching, and a support frame 103 arranged at the bottom of the solar reflector support 101 , the support frame 103 and the solar reflector support 101 are connected and supported by a universal joint bracket 104 , and a dual-axis clock type sun tracking control device 6 is also arranged on the support frame 103 .

[0028] The two-axis clock type sun tracking control device 6 includes four guide wheels 601 respectively arranged in four directions of east,...

Embodiment 2

[0030] Embodiment two: see Figure 1-Figure 5 The structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that: during the drying process, a large amount of hot steam will be generated, and if the feces are directly processed without fermentation Drying wastes a lot of biogas resources. Therefore, in order to be able to use the biogas resources and solar energy in the feces more reasonably, a powerful exhaust fan 209 and an exhaust hose 210 are communicated on the upper cover of the dryer, and a sealed fermentation cooling chamber 5 for fermenting the feces is provided. , before the feces are dried, the feces fermentation should be carried out in the sealed fermentation cooling chamber 5, and the collection of biogas. The bottom of the sealed fermentation cooling chamber 5 is laid with a feces fermentation heat exchange pipe 501, and the feces fermentation heat exchange pipe 501 is connected to th...

Embodiment 3

[0034] Embodiment three: see Figure 1-Figure 5 , the structure of this embodiment is basically the same as that of Embodiment 2, and the similarities will not be repeated. The difference is that a water tank 502 is provided on the sealed fermentation cooling chamber 5, and a water tank 502 is also provided in the water tank 502. The water tank heat exchange pipe 503, the exhaust hose 210, the water tank heat exchange pipe 503, and the excrement fermentation heat exchange pipe 501 are connected in sequence, so that the high-temperature waste gas produced by drying the feces can be fully utilized to convert the energy in the high-temperature waste gas For high temperature domestic water.

[0035] Embodiment three: see Figure 1-Figure 6 , the structure of this embodiment is basically the same as the above-mentioned embodiment, and the similarities will not be repeated. The difference is that the fertilizer making system also includes a function expansion chamber 7 for supporti...

Abstract

The invention belongs to the technical field of solar energy application. A fertilizer making system utilizing solar energy to dry feces, comprising a spherical reflective focusing solar device, a conical inner-rotating dryer arranged in the middle of the spherical reflective focusing solar device, a dry material storage tank and a grouting control system; the spherical reflective The concentrated solar energy device is controlled by a dual-axis clock type sun tracking control device, and the above-mentioned components are internally connected with pipes, and the control circuit is connected with each driving device. The invention can perform harmless and resource-based disposal before the feces enter the urban sewage treatment plant, realize high-temperature sterilization and dry fertilizer making, and solve the problem that the waste sludge produced by the sewage treatment plant cannot be used as plants due to excessive heavy metals The problem of fertilizer for growth, the heat generated at the same time can be used as a heating source for bathing water, and the biogas generated in the fermentation cooling room can also be collected as fuel, reducing the waste of resources. And the structure is simple and easy to implement.

Description

technical field [0001] The invention belongs to the technical field of solar energy application, and in particular relates to a fertilizer making system which utilizes solar energy to dry feces. Background technique [0002] Nowadays, China is promoting urbanization construction, and each community will produce a large amount of feces that need to be treated. If the organic matter, nitrogen and phosphorus in the feces are directly discharged, it will cause water pollution and emit rich ammonia, hydrogen sulfide, acid alcohols, sulfides, etc. Harmful gases with odor components, although the construction of the community is equipped with sewage pretreatment facilities such as septic tanks, but the post-treatment will eventually be transported to the urban sewage treatment plant for treatment. Feces are easily polluted by more heavy metals in the process of entering the urban sewage treatment plant through the sewer after simple fermentation in the septic tank, and the waste sl...
