Control system and control method for wastes in three-waste integrated reactor

Abstract

The invention provides a control system for wastes in a three-waste integrated reactor. The control system for the wastes in the three-waste integrated reactor comprises a control center, a first measurement component, a second measurement component, a third measurement component and a mixer, wherein the control center calculates a control quantity according to a given value and a variable elementfed back by a measurement component, adjusts the opening degree of a control valve through the control quantity, and adjusts the ratio of the different wastes; the first measurement component is usedfor measuring the moisture content of the wastes, and feeding back the measured moisture content to the control center; the second measurement component is used for measuring a heat value of the wastes, and feeding back the measured heat value to the control center; the third measurement component is used for measuring a viscosity value of the wastes, and feeding back the measured viscosity valueto the control center; and the mixer is used for mixing the different wastes in a ratio, and mixing the wastes with fuel gas. The control system for the wastes in the three-waste integrated reactor is capable of effectively solving the problems of wrong calculation of waste filling and proportioning, insufficient waste combustion, structure blockage, and the like.

Description

technical field [0001] The invention relates to the technical field of three-waste treatment, in particular to a control system and a control method for waste in a three-waste integrated reactor. Background technique [0002] Hazardous waste incineration device is suitable for incineration disposal of salty waste liquid, waste gas and waste solid. Different wastes have different characteristics such as shape and calorific value. In the traditional process, when filling different wastes into the combustion furnace, the filling ratio of different wastes is usually calculated manually. Manual calculation and weighing often have a certain error rate and error. The combustion of waste in the environment has a certain impact. [0003] With the development of automatic control, there has been a scheme of filling different wastes into the combustion furnace through automatic control in the prior art. However, the existing automatic control system is limited by the combustion furn...

AI Technical Summary

Problems solved by technology

However, the existing automatic control system is limited by the combustion furnace on the one hand, which leads to problems such as high crystallization, high slagging and high corrosion in the incineration device containing salty waste liquid, waste gas, and waste solids, which may easily cause equipment blockage or low service life of the equipment. ; On the other hand, the existing control system lacks consideration of the diversity of waste. Even if the same kind of waste is injected into the furnace each time, the waste still has different characteristics, and the preset waste ratio is different. The combustion effect is different at different time periods, it is difficult to ensure full combustion at all times, resulting in the blockage of the combustion furnace by insufficiently burned waste
