Description

No fire grate double shaft type coal combustion energy-saving environmental protection boiler

The utility model relates to a kind of boiler, especially a kind of no fire grate double shaft type coal combustion energy-saving environmental protection boiler.

A large amount of flue gas serious environment pollutions of present various boiler combustion dischargings, after fire coal changes fuel oil into and does fuel, coal pollutes to be alleviated, greasy dirt dyes and increases the weight of, environment is still produced destruction, and its hazard ratio fire coal is also serious, adds in the scarcity of China's oil resource than coal resource, therefore uses fire coal to be still main heating power energy access from now on.The fuel of boiler use now all is loose coal and fine coal; its discharged flue gas contains harmful substances such as a large amount of carbon monoxide, carbon dioxide, sulfur dioxide, chloride; though still have many harmful substances to enter atmosphere through purified treatment; there is the people on the conventional boiler basis, to carry out the trial of moulded coal mode in recent years; but its combustion system does not have radical change; promptly do not solve atmospheric environment protection, more aggravated the waste of the energy.

The purpose of this utility model is to provide a kind of no fire grate double shaft type coal combustion energy-saving environmental protection boiler, and this boiler does not have fire grate, adopts twin furnace tube briquet, and desulfurization before the coal type burning, is different from the combustion system of conventional boiler.

For achieving the above object, this utility model comprises drum part and stove tube part, the stove tube partly comprises two Lu Tang, two bellows and two dreg discharging box, a fume collecting chamber and one second burning chamber, one air blast is respectively arranged in each bellows, and drum partly is divided into lower drum, two drums, three drums; Lower drum is adjacent with two stove halls, alternate with two drums, second burning chamber is arranged between the two, have some stay pipes to be connected with lower drum and two drums respectively in second burning chamber, some fire tubes are arranged in two drums, communicate with last fire tube in second burning chamber and three drums respectively, also have some heat pipes in second burning chamber and two drums, the heat pipe upper end is positioned at two drums, and the lower end is positioned at second burning chamber, center fixed has heat-conducting medium in the heat pipe on tube sheet; The last fire tube that some times type complications are arranged in three drums, the lower end of last fire tube link to each other with two drum internal fire pipes respectively, and the upper end converges at the smoke evacuation chamber, water inlet is arranged in the lower drum, in two drums delivery port is arranged, water inlet and delivery port is arranged in three drums, the twin furnace tube and in some stove pyrenes are arranged, fan housing is arranged in the dreg discharging box, the stove pyrene is arranged above and below, and can take out or move up and down, and fan housing is movable the connection, can lift, in lower drum and three drums, a sewage draining exit be arranged respectively; The another kind of mode of this boiler is that two drums do not have three top drums about having only.

After adopting this structure, boiler is cold operation, has prolonged boiler life, desulfurization was handled before moulded coal, moulded coal burning had been adopted in burning, reduced atmosphere pollution, was shaped as cabinet-type, its volume is little, and is in light weight, convenient transportation, multi-use, can warm oneself, drinkable again, have a bath, be particularly suitable for family and use, and thermal efficiency height is energy-saving type boiler.
