In order to achieve the above object, the present invention realizes by the following technical solutions:
There is multiple bottom flue structure that independently can control gas channel, comprise the bottom flue be made up of regenerator main wall and regenerator list wall, bottom flue is inner along high to being divided into several layers, the horizontal dividing wall of bottom flue is established in every layer of centre, the gas channel be made up of bottom flue lining brick, bottom flue horizontal subdivision wall/bottom flue shop fixtures brick, the horizontal dividing wall of bottom flue respectively lattice little of regenerator is communicated with and forms individual air stream passage, and each gas channel ingress is equipped with setting device.
Described bottom flue horizontal subdivision wall is from top to bottom arranged in ladder along the corresponding little partition wall place of regenerator of gas inflow direction, arranges with bottom flue horizontal subdivision wall interval, layer both sides.
Described bottom flue horizontal subdivision wall is connected with the little partition wall of regenerator by the little partition wall of bottom flue at corresponding regenerator little partition wall place, forms gas buffer chamber in its junction by bottom flue lining brick, the little partition wall/regenerator of bottom flue little partition wall/heating system center partition, bottom flue horizontal subdivision wall/bottom flue shop fixtures brick.
Described setting device is manual regulation flap valve or self-acting valve plate valve.
Compared with prior art, the invention has the beneficial effects as follows:
1) by being separated to form multiple gas passage to bottom flue, and then realizing carrying out accurate tolerance flow-dividing control to the low-grade gas/air of heating coke-oven in outside, improve combustion chamber length to the homogeneity of temperature distribution and accuracy;
2) automatic control can be realized, improve operating environment, reduce labor intensity, increase work efficiency and security;
3) gas flow of the little lattice of each regenerator can be entered by fine adjustment, improve energy utilization rate, energy-saving and cost-reducing.
