Problems solved by technology

[0002] Before anaerobic fermentation of organic waste materials (including urban waste, human and animal manure, plant straw, residual sludge from sewage treatment plants, etc.), a series of treatments are required, and organic waste gas materials are anaerobically fermented in the form of feed liquid During the fermentation process, the fermentation environment of the feed liquid, such as the PH value, will change, and the fermenting bacteria need to be within a certain PH value range to maintain high-efficiency fermentation. The existing fermenter lacks automatic control means

Embodiment Construction

[0027] In order to make those skilled in the art understand the present invention more clearly, a more detailed description will be made below in conjunction with the accompanying drawings, but these descriptions are not intended to limit the protection scope of the present invention.

[0028] Such as figure 1 As shown, it is a flow chart of an embodiment of the feed liquid fermentation deployment control method of the present invention, including: receiving the pH value signal of the feed liquid; comparing the pH value signal with the preset pH value target range, and if it exceeds the stated The PH value target range then calculates the amount of acid or alkali that needs to be added to reach the PH target range; add acid or alkali to the feed liquid according to the calculated acid amount or alkali amount to make the feed liquid reach the PH value target range . Since the pH value of the feed liquid changes continuously during the fermentation process, the technical soluti...

Abstract

The invention discloses a fermentation tank, and a method, equipment and a system for controlling fermentation blending of feed liquid. The method comprises the following steps of: receiving pH value signals of the feed liquid; comparing the pH value signal with a preset pH value target range, and calculating the amount of acid or alkali which is required to be added for reaching the pH value target range if the pH value signal exceeds the pH value target range; and adding the acid or the alkali to the feed liquid according to the calculated amount of the acid or the alkali so as to make the pH value of the feed liquid reach the pH value target range. According to the fermentation tank, the method, the equipment and the system, the feed liquid can be automatically blended in the fermentation process.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to a fermenter and a method, equipment and system for controlling the fermenting and blending of feed liquid. Background technique [0002] Before anaerobic fermentation of organic waste materials (including urban waste, human and animal manure, plant straw, residual sludge from sewage treatment plants, etc.), a series of treatments are required, and organic waste gas materials are anaerobically fermented in the form of feed liquid During the fermentation process, the fermentation environment of the feed liquid, such as the PH value, will change, and the fermenting bacteria need to maintain high-efficiency fermentation within a certain PH value range. The existing fermenter lacks automatic control means. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fermentation tank and a method, equipment and system for c...
