摘 要:城市中有機生活垃圾處理主要依靠人力分揀,回收利用率低,加工自動化程度不高。本文通過分析有機生活垃圾處理設備的工作流程,設計了一種的有機生活垃圾處理設備控制系統。該系統以可編程邏輯控制器為控制核心,以監視與控制通用系統組態畫面為上位機,實現對有機生活垃圾處理設備作業過程的自動控制和實時監控,滿足了有機生活垃圾處理的工藝控制要求,具有一定實際意義。

Abstract: In view of the shortcomings of organic domestic waste processing in cities, which mainly rely on manual sorting, its recycling rate is low, and the degree of processing automation is not high. By analyzing the work flow of organic domestic waste treatment equipment, a new control system of organic domestic waste treatment equipment is designed in this paper. The system takes the programmable logic controller as the control core and the monitoring and control general system configuration screen as the upper computer to realize the automatic control and real-time monitoring of the operation process of organic domestic waste treatment equipment, which meets the process control requirements of organic domestic waste treatment and has certain practical significance.

隨著生活條件的不斷改善,城市生活垃圾產生量也逐年增多,現有垃圾大致可以分為可回收垃圾、有機生活垃圾、有害垃圾及其他不可回收垃圾4類[1]。其中,有機生活垃圾占比超過50%,包括日常廚余垃圾,如剩菜、果皮等富含脂肪、蛋白質、碳水化合物的有機物質。傳統的垃圾處理方式多為焚燒與填埋處理。但是焚燒時需要消耗大量燃料,同時也會產生大量污染物;而有機垃圾填埋不當又極易腐爛變質,污染現有土地資源。目前對生活垃圾較為合理的處理方式是對經過分揀的有機垃圾進行粉碎、壓榨、混合攪拌后生成有機肥料,將有機生活垃圾進行二次資源開發利用,達到“減量化、資源化、無害化”的垃圾處理要求[2]。本文在有機生活垃圾處理設備的結構設計基礎上,以可編程邏輯控制器(Programmable Logic Controller,PLC)為控制核心,以三相異步電機、變頻器、氣缸和油泵等為執行元件,設計出有機生活垃圾處理系統的電氣控制系統。……
