The dust cleaning device is simple in structure and convenient to install, use, operate and maintain; dust is impacted, raised and taken away through momentary expansion of compressed gas, so that scaling is avoided; and the energy consumption and cost are low.
Description
Technical field
The utility model relates generally to the processing of dust stratification in a kind of industrial high temperature flue gas bundled tube cooling device, specifically is a kind of bundled tube cooler dust stratification clearing apparatus.
Background technology
Often utilize the bundled tube cooler to cool off the dust-laden high-temperature flue gas in the commercial Application; The bundled tube cooler mainly is made up of tube bank, back blowing machine and support three parts; Tube bank comprises air inlet loudspeaker, ash bucket, cooling tube, curb girder and crossbeam etc.High-temperature flue gas gets into cooling tube through the import loudspeaker, and cold air is blown into interbank by back blowing machine, and through tube bank, high-temperature flue gas and air carry out heat exchange to realize the purpose of cooling.The high-temperature flue gas of cooling gets into pipeline through the air outlet on the ash bucket and discharges.
But in practical application,, very easily cohere at tube wall inner because dust in flue gas or gas are separated out under the situation of cooling; Especially the flue gas that contains stickums such as tar class after long cooling operation, is easy to after the deposition fouling occur and causes the pipe ventilated area to reduce, and resistance increases, and influence flowing and cooling off of air-flow; Cause obstruction when serious, influence the operation of upstream and downstream equipment, so that cause the accident.Fouling occurs, and has only through after shutting down, and adopt and carry out artificial deashing through perforate, work under bad environment, link is loaded down with trivial details, and workload is big; Perhaps adopt mechanical type to remove, fault is many, and energy consumption is high.If dangerous gas or dust can cause gas or dust to reveal, so that cause personal injury even accident.
The utility model content
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of bundled tube cooler clearing apparatus is provided; Be a kind ofly to utilize high-voltage pulse valve moment to eject gases at high pressure; Get into injection through winding-up pipe, spray to each cooling tube with the extremely short time (0.065 ~ 0.085 second), wash away the cooling tube inwall; Drive the dust that has dashed through the gas rapid movement that expands simultaneously and move down, the dust settling that makes fouling is in ash bucket; Realize in time removing dust stratification, prevent the generation of fouling.
The utility model is realized through following technical scheme:
A kind of bundled tube cooler dust stratification clearing apparatus; Include the cooler body; Be provided with the plurality of rows cooling tube in the cooler body; It is characterized in that: the upper fixed of per two rows between the cooling tubes has a winding-up pipe, is respectively equipped with on each winding-up pipe and corresponding cooling tube top nozzle position spout one to one; Said winding-up Guan Yiduan stretches out outside the cooler body and is communicated with air supply system.
A kind of bundled tube cooler dust stratification clearing apparatus; It is characterized in that: said winding-up pipe includes straight tube and two groups of 90 ° of bend pipes; Straight tube and two groups of bend pipes are arranged and are fishbone, and an end of said bend pipe is connected with straight tube, the top mouth of pipe of the corresponding cooling tube of other end subtend.
A kind of bundled tube cooler dust stratification clearing apparatus; It is characterized in that: said air supply system includes the high-pressure hose of connection in winding-up pipe outer end; The outer end of high-pressure hose is communicated with the winding-up short tube, and the other end UNICOM of said winding-up short tube is in the pulse valve of electromagnetic impulse valve, and pulse valve also is linked with gas manifold; Said gas manifold UNICOM is in gas bag, and the magnetic valve of said electromagnetic impulse valve is connected in controller through the control cable.
A kind of bundled tube cooler dust stratification clearing apparatus is characterized in that: the spout center line of winding-up pipe and the central lines of corresponding cooling tube, and the winding-up pipe is positioned at corresponding cooling tube upper end 280-320mm.
The utility model in use; Can be according to what of cooling tube number of the arrangement; High-pressure hose, winding-up pipe, the control cable of many cover gas manifolds, electromagnetic impulse valve, winding-up short tube, strip slip-collar are installed on gas bag, and unified access controller is swept to realize respectively clearing.Can select the kind of compressed gas source according to the character of gas in the airflow line and dust simultaneously; General application of compressed air is as source of the gas; Like inflammable and explosive gas or dust, can adopt inert gas as compressed gas source.
The utility model adopts high-pressure hose to connect and can be easy for installation and removal, and eliminates the thermal deformation that variations in temperature causes; Described winding-up pipe is installed in the centre of corresponding two row's cooling tubes and does not influence high-temperature flue gas entering cooling tube, plays the effect of certain drainage simultaneously; The cooling tube inwall that the air-flow of ejection is aimed at is eliminated dust stratification through the impact of air-flow and the expansion of gas, prevents the generation of fouling.
Described controller can be according to the start and stop of actual conditions automatic or manual control magnetic valve.
The utility model has the advantages that:
The utility model is simple in structure, easy to install; Through the moment impact of Compressed Gas, and the dust and take away dust kicked up behind the expansion of compressed gas, the dust that coheres can be cleaned fast; Prevent the generation of fouling, recover the normal operation of high-temperature flue gas in tube bank; While less energy consumption, low, the convenient operating maintenance of cost.

The specific embodiment
A kind of bundled tube cooler dust stratification clearing apparatus includes cooler body 3; Be provided with plurality of rows cooling tube 1 in the cooler body 3, the upper fixed of per two rows between the cooling tubes 1 is equipped with a winding-up pipe 2, and winding-up pipe 2 is made up of straight tube 2-2, two groups of 90 ° of bend pipe 2-1, and straight tube 2-2, two groups of 90 ° of bend pipe 2-1 are arranged in fish bone well.The end of said bend pipe 2-1 is connected with straight tube 2-2, the top mouth of pipe of the corresponding cooling tube 1 of other end subtend.
Straight tube 2-2 stretches out cooler 3 in the end; And the high-pressure hose 4 through having clip links with winding-up arm 5; The other end UNICOM of winding-up arm 5 is in the pulse valve 6-1 of electromagnetic impulse valve 6, and pulse valve 6-1 also is linked with air feed short tube 7, gas bag 8 UNICOMs of air feed short tube 7 and air feed; The magnetic valve 6-2 of electromagnetic impulse valve 6 is connected in controller 10 through control cable 11; The spout center line of the bend pipe 2-1 of described winding-up pipe and the central lines of cooling tube 1, and bend pipe 2-1 is positioned at about the 300mm of cooling tube upper end.
When having dust stratification to occur in the cooling tube 1; Can open pulse valve 6-1 through the magnetic valve 6-2 on the controller 10 startup electromagnetic impulse valves 6, the compressed air in the gas bag 8 manage 2 through gas manifold 7, pulse valve 6-1, winding-up arm 5, winding-up; Time with extremely short sprays into Compressed Gas in cooling tube 1; Compressed Gas is expansion rapidly cooling tube 1 in the dust stratification in impacting cooling tube 1, and the wind speed in the kick up dust stratification and the cooling tube 1 that increases sharply, drive dust-contained airflow move down and get into ash bucket 9; Like this, the dust stratification in the cooling tube 1 is eliminated very soon, has prevented the generation of fouling; In practical application, can lack the suitably a plurality of clearing apparatus of layout according to the arriving of the number of permutations of cooling tube 1.
