2, CH
4, H
2S, C0
2, N
2With a certain amount of tar and carbon black, the about 5016-7200kJ/Nm of its calorific value
3, because tar and carbon black very easily adhere on control valve, inner member and the tube wall, even dry and hard one-tenth pitch shape, to moment the reliable gas maked coal that cuts off supply with and bring bigger technical difficulty, so Industrial Boiler seldom uses gas maked coal.
The utility model content
Technical problem to be solved in the utility model be to provide a kind of simple and reasonable, cost of manufacture is low, the coke cleaning device of the Industrial Boiler of the use gas maked coal of flexible operation, safe and reliable, long service life, to overcome weak point of the prior art.
The technical scheme in the invention for solving the above technical problem is: a kind of coke cleaning device that uses the Industrial Boiler of gas maked coal, comprise the gas maked coal inlet pipe of joining with the combustion of industrial boiler device, the gas maked coal inlet pipe is provided with magnetic valve, its constitutional features is to be respectively arranged with first hand sluice valve and second hand sluice valve before and after the magnetic valve, the vapour pipe inlet inserts between first hand sluice valve and the magnetic valve, perhaps insert between second hand sluice valve and the magnetic valve, be provided with coke discharging tube between first hand sluice valve and/or second hand sluice valve and the magnetic valve.
The branch road that is divided into two or more in the middle of the above-mentioned gas maked coal inlet pipe, the terminal burner that merges back and Industrial Boiler of this branch road joins, and wherein, every branch road is provided with one or more magnetic valve.
Be divided into two branch roads in the middle of the above-mentioned gas maked coal inlet pipe, be respectively first branch road and second branch road, be provided with first magnetic valve in first branch road, be respectively arranged with first hand sluice valve and second hand sluice valve before and after first magnetic valve, vapour pipe first inlet inserts between first hand sluice valve and first magnetic valve, perhaps insert between second hand sluice valve and first magnetic valve, be provided with first coke discharging tube between first hand sluice valve and/or second hand sluice valve and first magnetic valve, be provided with second magnetic valve in second branch road, be respectively arranged with the 3rd hand sluice valve and the 4th hand sluice valve before and after second magnetic valve, vapour pipe second inlet inserts between the 3rd hand sluice valve and second magnetic valve, perhaps insert between the 4th hand sluice valve and second magnetic valve, be respectively arranged with second coke discharging tube between the 3rd hand sluice valve and/or the 4th hand sluice valve and second magnetic valve, and/or be provided with the manual switch valve before the inlet of its middle steam tube.
The terminal back that merges of above-mentioned branch road joins with escape pipe, and the burner of escape pipe and Industrial Boiler joins.
Owing to will realize the automatic control of Industrial Boiler, key is to guarantee the supply of reliable cut-out of moment gas maked coal, just guarantees the magnetic valve works better, will be that example is elaborated with first magnetic valve that cleans in first branch road below.During cleaning, at first close first hand sluice valve and second hand sluice valve, open the preceding manual switch valve of corresponding vapour pipe inlet then and feed high-temperature steam, high-temperature steam is to pipeline between first hand sluice valve and second hand sluice valve and corresponding valve member, comprise first magnetic valve, carry out tar and sooty and remove, then open coke discharging tube and discharge tar impurity etc., close coke discharging tube after cleaning finishes again, open first hand sluice valve and second hand sluice valve, can put into operation again.
When the utility model applies to a boiler, two branch roads can be set, the purpose that two branch roads are set is the normal operation of not interrupting Industrial Boiler, when branch road coke cleaning wherein, but another branch road works better.When the utility model applies to two boilers, three branch roads can be set, wherein two branch roads are normal air feed usefulness, and the 3rd branch road is the coke cleaning branch road, and this coke cleaning branch road can be shared by preceding two branch roads.
