Description
Technical Field
The invention relates to an operation process for treating and recycling filter mud in the sugar industry field, in particular to a high-efficiency filter mud hot water mixer.
Background
In the sugar production process of the sub-method cane sugar factory, because non-sugar organic substances such as protein, pectin, organic acid and the like contained in the extracted cane juice are unfavorable for sugar boiling crystallization, the cane juice needs to be clarified. The method is characterized in that substances such as calcium hydroxide, sulfur dioxide, phosphoric acid and the like are added into cane juice to precipitate non-sugar organic matters such as protein, pectin, organic acid and the like, and the precipitate is intercepted by a vacuum suction filter to form filter residue which is called filter mud. A sugarcane mill that squeezes ten thousand tons a day can produce about 3 thousand tons of sludge per squeezing season, based on processing one ton of sugarcane to produce 2.5% sludge. The filter mud comprises the following components: 78.2% moisture, 2.1% sugar, 4.3% fiber, 2.5% protein, 3.6% cane wax and cane fat, 9.3% ash. Because the filter mud has the characteristics of high water content, difficult ventilation and the like, the filter mud is difficult to dry naturally and is very easy to be polluted by mixed bacteria, and the polluted filter mud enters the soil to further influence the growth of crops; the filter mud is stacked in a factory, after the filter mud is contacted with air for a period of time, sugar in the filter mud is decomposed and fermented with bacteria and then forms foul smell, so that land resources are occupied, air is polluted, underground water sources are polluted, the filter mud becomes waste which is 'laid in place and cannot be used', and the sugar refinery pays for transportation of the filter mud and land occupation every year. Therefore, the research on how to treat the filter mud of the cane sugar factory at low cost is an environmental protection problem for controlling and eliminating the pollution source formed by the solid waste in the sugar factory.
In order to solve the problem of filter mud pollution, a process which is low in investment, small in occupied area and low in cost and can effectively eliminate the filter mud pollution of a sub-process sugar refinery is provided. The process comprises the steps of directly putting filter mud into a high-efficiency filter mud hot water mixer, directly mixing the filter mud with hot water to form pumpable thin mud, then conveying the thin mud to a sugarcane pressing production line as pressing permeating water by using a pump, pressing the thin mud together with sugarcane newly entering the pressing production line, and then feeding the thin mud into a boiler along with bagasse for combustion, so that the filter mud generated in a sub-process sugar factory is effectively eliminated, and substances which cannot be combusted in the filter mud are finally discharged in the form of boiler ash.
The key equipment of the process for eliminating the filter mud pollution of the sub-method cane sugar factory is a high-efficiency filter mud hot water mixer, and no related literature reports a high-efficiency filter mud hot water mixer which is low in energy consumption, simple in treatment method and suitable for sugarcane sugar manufacturing enterprises to date.
Disclosure of Invention
The invention aims to provide a high-efficiency mud filtering hot water mixer which is low in energy consumption, low in investment and simple in treatment method.
The invention is realized in this way, a high-efficient hot water mixer of mud filtration is made up of parts such as the tank, porous baffle, removable end cap, inlet pipe of mud filtration, agitator, hot water inlet pipe, slurry outlet pipe, silt discharge pipe, its characteristic is: the flange at the upper part of the tank body is connected with the detachable end cover; a sludge inlet pipe is arranged on the detachable end cover and is connected with a sludge conveyor; the detachable end cover is provided with a hot water inlet pipe which is connected with the squeezing and permeating hot water pipe; the middle part of the tank body is provided with a porous partition plate which divides the space in the tank body into an upper part and a lower part, and the upper part and the lower part are both provided with stirring paddles; the lower part of the tank body is provided with a dilute slurry outlet pipe which is connected with a slurry pump; a silt discharge pipe is arranged at the conical bottom of the tank body and is connected with a silt receiving pool; a stirrer is arranged in the center of the tank body.
The stirrer adopted by the high-efficiency mud-filtering hot water mixer is of a multilayer stirring structure, and the blades of the stirrer adopt two-blade paddles or turbines.
The cone angle of the porous partition plate adopted by the high-efficiency sludge-filtering hot water mixer is 150 degrees, and round holes with the diameter of more than 15mm are uniformly distributed.
The working principle of the invention is as follows: during operation, hot water enters the tank body through the hot water inlet pipe, after the tank body is filled with water, the filter mud is sent to the filter mud inlet pipe and enters the upper space of the tank body, the filter mud is mixed and dissolved with the hot water under the action of the stirring paddle in the upper space, the part of filter mud which is not dissolved uniformly penetrates through the porous partition plate and enters the lower space, and the filter mud is continuously mixed and dissolved with the hot water under the action of the stirring paddle in the lower space, so that the full extension of mud-water mixing time is realized, the filter mud is ensured to be completely dissolved in the hot water, the residual insoluble silt is settled at the cone bottom, and the silt settled at the cone bottom is discharged through the silt discharge pipe; and (4) discharging the thin mud slurry formed by dissolving the filter mud in hot water out of a thin mud slurry outlet pipe, entering a mud pump, and conveying the thin mud slurry to a sugarcane pressing production line through the mud pump.
Compared with the prior art, the invention has the prominent substantive characteristics and remarkable progress that:
