Abstract
The utility model provides a dioxin preventing device pertaining to waste burning equipment, relating to waste treatment technique field. A necking pipe which can accelerate the airflow is connected with the smoke gas drain pipe of the second smoke chamber; the upper end and the lower end of the necking pipe are respectively connected with the smoke gas drain pipe and a spray tower flange. The necking pipe is a double layer structure; the inner layer is a necking pipe (4) and the outer layer is a straight pipe (3) whose pipe diameter is the same as the diameter of the smoke gas drain pipe of the second smoke chamber; 2 to 4 sprinkling heads which prong and extend into the straight pipe (3) and the necking pipe (4) are arranged at the necking position. The utility model sprays cooling water when the smoke gas flow is through the necking position and mutates and accelerates to make the 1100 centigrade high temperature instantaneously fall below 200 centigrade so as to effectively prevent the dioxin from regenerating, contributing to environment protection.
Description
Technical field
The utility model relates to the anti-dioxin generating apparatus in the technology of garbage disposal field, particularly garbage incinerating system.
Background technology
Along with economy is growing, medical treatment, chemical industry solid refuse and this class hazardous waste generation of waste liquid also sharply increase, and then human health is caused direct threat.The rotary kiln incineration treatment technology relatively is suitable for the processing to solid toxic pollutant material, but traditional rotary kiln incineration technology, normally when high temperature incineration flue gas during through excessive tank body, adopt atomized water spraying cooling method, this method cooling rate is slow, easily causes flue gas synthetic dioxin in temperature-fall period.Sample investigation report to the domestic rubbish disposal disposal facility pollutant emission situation of 47 key cities in the whole nation was once arranged, dioxin exceeding standard rate at 20 garbage burning factory flue gases that incinerator extracted is 57.1%, and the backward waste incineration facility dioxin that has exceeds standard more than 99 times.Studies show that,, can prevent effectively that dioxin from regenerating in the extremely short time when the high-temperature flue gas more than 1000 ℃ cools to below 200 ℃.
The utility model content
At the problem of above-mentioned prior art situation and existence, the purpose of this utility model provides and a kind ofly can effectively suppress dioxin and regenerate, and can make to prevent the dioxin generating apparatus in the garbage incinerating system that the dioxin concentration of flue gas effectively reduces.
The technical solution of the utility model is: prevent the dioxin generating apparatus in a kind of garbage incinerating system, it is characterized in that the necking down pipe that dual firing chamber's fume emission pipeline serial connection can make air-flow quicken, bottleneck is provided with the fountain head that stretches in the pipe.
The two ends of above-mentioned necking down pipe respectively are shaped on flange.
The necking down pipe is a double-decker, and its skin is caliber and the identical straight bobbin of dual firing chamber's smoke discharge pipe, and its internal layer is the necking down pipeline.
At the other cleaning door that stretches in the pipe that also is provided with of the fountain head of necking down pipe.
The utility model advantage compared with prior art: because dual firing chamber's fume emission pipeline serial connection necking down pipe, bottleneck is provided with the fountain head that stretches in the pipe, according to the pneumatics principle, when the quickening that must suddenly change of air-flow its flow velocity when the bottleneck, spraying cooling water herein, under the air blast effect, cooling water is excited into vaporific automatically, stick, be detained, collide, absorb with high-temperature flue gas, 1100 ℃ the high-temperature flue gas that can make bottleneck below instantaneous temperature reduction to 200 ℃, thereby prevented that effectively dioxin from regenerating.After tested, dual firing chamber's fume emission pipeline of necking down pipe has been installed, the content＜0.5TEQng/m of dioxin
3, be better than national standard, obviously reduced dioxin compound probability once more, help environmental protection.In addition,, can reduce high temperature resistant requirement, save cost subsequent parts material in the system because high-temperature flue gas temperature behind process necking down pipe has dropped to below 200 ℃.
Description of drawings
Fig. 1 is a structural representation of the present invention:
Fig. 2 is Fig. 1 vertical view.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The dioxin generating apparatus that prevents in the garbage incinerating system described in the utility model is the necking down pipe that air-flow is quickened in dual firing chamber's fume emission pipeline serial connection, the upper end of necking down pipe is shaped on flange 5, the lower end is shaped on flange 6, to be communicated with flue and spray column respectively; The necking down pipe is a double-decker, and its internal layer is a necking down pipeline 4, and its skin is the straight bobbin 3 of caliber and dual firing chamber's smoke discharge pipe same diameter, and the effect one of straight bobbin 3 is that the necking down position that can prevent necking down pipeline 4 is easily bent, the 2nd, and specious.Necking down pipeline 4 can be selected ferrous materials for use, or adopts the special anti-1300 ℃ high temperature of the applicant and the material of 40% acidity to make long service life.Be provided with at bottleneck and run through 2-4 the fountain head 2 that stretches in straight bobbin 3 and the necking down pipeline 4, run through 2-4 the cleaning door 1 that stretches in straight bobbin 3 and the necking down pipeline 4, stopped up by cigarette ash in the bottleneck preventing fountain head 2 other also being provided with.The water spray of necking down pipe is regulated the shower water valve size by the temperature sensor in the pipe, manual adjustment in the time of manually, and for to regulate the water inlet motor-driven valve automatically according to design temperature, assurance device is in optimum condition in the time of automatically.Embodiment necking down pipe is a vertical and cylindrical, according to implementing the place designing requirement, also can be designed to horizontal, square tube shape.
Claims (4)
1. prevent the dioxin generating apparatus in the garbage incinerating system, it is characterized in that the necking down pipe that dual firing chamber's fume emission pipeline serial connection can make air-flow quicken, bottleneck is provided with the fountain head that stretches in the pipe.
2. according to preventing the dioxin generating apparatus in the described garbage incinerating system of claim 1, it is characterized in that the two ends of necking down pipe respectively are shaped on flange.
