Description

Clean garbage incinerator stoker infiltration filtrating collecting system

Technical Field

The utility model relates to a waste incinerator technical field, in particular to clean waste incinerator stoker infiltration filtrating collecting system.

Background

With the acceleration of the urbanization process, the living standard of people is improved, the land resources are increasingly tense, the landfill site is closed, the phenomenon of the refuse surrounding is more and more intense, the country highly pays attention to the environmental protection, a new refuse treatment mode, namely refuse incineration, flowers all the time in China in recent years, not only treats the refuse, solves the problem of the refuse surrounding, but also changes waste into valuable, generates electricity and benefits people. The process flow of the waste incineration treatment comprises the following steps: the primary garbage is transported in a closed manner to enter a garbage storage bin, fermented for 5-7 days in the garbage storage bin, thrown into a garbage chute through a garbage grab bucket crane, pushed to a grate through a material pusher below the garbage chute, blown into a hearth through an air hole from below the grate by more than two hundred degrees of primary air, fully combusted on the grate in five stages of drying, gasification, combustion, burnout and cooling, generated hot flue gas absorbs heat through a waste heat furnace, furnace water is heated into superheated steam to push a steam turbine to rotate, and the steam turbine drives a generator to generate electricity. The flue gas discharged from the waste heat furnace passes through a set of flue gas purification system, and is subjected to desulfurization, denitration and dust removal, and finally reaches the standard to be discharged. The garbage can generate leachate in the fermentation process of the garbage storage bin, and in order to promote better drying of the garbage after entering the furnace, a leachate collecting system is arranged below the material pusher. The current garbage incinerator is various, and the percolate collecting system is different, but how to collect the percolate under the pusher more cleanly is a difficult problem in the industry.

The percolate collecting system under the material pusher used in the market at present has several problems that 1. the percolate collecting system is often blocked to influence combustion because the percolate in the garbage has high viscosity and contains sludge; 2. percolate leakage is often caused when a blocked percolate collecting system is cleaned, so that the production site is foul; 3. the production cost is high, the structure is complex, and even frequent maintenance is needed to maintain normal operation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

As shown in figure 1, a clean downward-osmosis filtrate collecting system of a garbage incinerator stoker 4 comprises a hearth 1, a chute 2, a grate 3, a stoker 4 and a percolate collecting hopper 5. This is the existing structure, mainly drying, gasifying, burning out, cooling, not too much illustrated and limited herein.

And a reducer pipe 6 and a sewage storage bin 8 are sequentially connected to the narrow opening below the percolate collecting hopper 5. The reducer pipe 6 further narrows the pipe diameter, which is beneficial to the centralized downward flow and collection of the percolate, and improves the collection efficiency. The sewage storage bin 8 can store a certain amount of sludge, and is favorable for the precipitation and collection of the sludge.

Also comprises a collecting tank 13 for storing percolate, a small cart 10 for collecting sludge and a flushing device. Solid-liquid separation is carried out on the sludge and the percolate through the collecting tank 13 and the trolley 10, and pertinence and high efficiency of treatment are facilitated. The flushing device mainly cleans the conveying pipe, so that a small amount of sludge is prevented from entering the conveying pipe to cause siltation, and other impurities can be prevented from adhering.

The reducing pipe 6 is communicated with the collecting tank 13 through a conveying pipe, the percolate collecting hopper 5 is provided with a gate valve 7 for controlling the opening and closing of the inlet pipe mouth of the conveying pipe, and a blowoff valve 9 for discharging sludge is arranged at the bin mouth of the sewage storage bin 8. The pipe orifice of the delivery pipe connected with the reducer pipe 6 is positioned between the gate valve 7 and the drain valve 9. The gate valve 7 is convenient for control mud outflow when clearance dirt storage storehouse 8 on the one hand, avoids mud outflow small handcart 10 to cause the production place to pollute, and on the other hand is closed when washing the conveyer pipe, can strengthen the washing effect of conveyer pipe. The blowoff valve 9 can control the discharge of the sludge in the sewage storage bin 8, and the blowoff valve 9 is normally closed in normal production. In order to prevent more sludge in the percolate from blocking the percolate collecting hopper 5 or the percolate conveying pipe, the gate valve 7 can be closed periodically, the drain valve 9 is opened, the sludge in the sewage storage bin 8 is conveyed to the garbage bin through the small trolley 10, the clean treatment is realized, and the environment of a production place is kept clean.

The position of the small handcart 10 is opposite to the bin opening of the sewage storage bin 8, the flushing device is communicated with the conveying pipe, a drainage pipeline is formed between the percolate collecting hopper 5 and the collecting pool 13, and a sewage discharge pipeline is formed between the percolate collecting hopper 5 and the sewage storage bin 8. Two pipelines for solid-liquid separation and discharge are beneficial to the targeted treatment in the later period, and internal blockage or other adverse conditions are also avoided.

The flushing device comprises a connecting pipe, a flushing ball valve 11 and a flushing water pump 12, wherein the flushing water pump 12 is cleaned by extracting industrial water or circulating water in a plant area. The flush water pump 12 can increase the pressure of the flush water, which is beneficial to cleaning the conveying pipeline. The rinse water ball valve can isolate leachate, preventing leachate from flowing backwards to the rinse water pump 12.

The conveying pipe is provided with a peephole 14 for observing the circulation condition, so that the normal or abnormal conveying and circulation of the leachate can be conveniently and periodically checked by people.

The gate valve 7 has a normally open state, an adjusting state and a closed state, and is adjusted according to use requirements.

The reducer pipe 6 and the sewage storage bin 8 are both made of anticorrosive stainless steel materials, so that the service life is prolonged, and the structural strength is ensured.

The working principle is summarized as follows: the leachate carrying the sludge enters the reducer pipe 6 through the leachate collecting hopper 5, the gate valve 7 is normally opened at the moment, and the leachate normally flows downwards. The sludge is gradually gathered in the sewage storage bin 8 through the reducer pipe 6, and the percolate is also accumulated to a certain liquid level and then flows into the collection tank 13. When the sludge is accumulated more, the drainage effect of the percolate is stronger. When the sludge storage capacity is too large, the gate valve 7 is adjusted or closed, the blow-down valve 9 is opened, and the sludge is transferred to the small handcart 10 and then is transported and treated. Meanwhile, the conveying pipe is cleaned through the flushing device, and sludge impurities are removed. When the blowoff valve 9 is opened, the gate valve 7 can be opened, and the flow is controlled by adjusting the opening degree, so that the small trolley 10 is prevented from overflowing to pollute the production place.
