SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming present when opening the kiln and overhauing, there is kiln temperature and flue gas temperature can be less than normal temperature, when the flue gas temperature is less than 100 ℃, there is the sack that the moisture in the flue gas can not the gasification easily makes the sack of sack cleaner to glue the ash caking, need to change sack reduction in production efficiency, the dioxin index is on the high side can not reach the not enough of environmental protection requirement in the flue gas, it is normal to provide one kind to make flue gas temperature, moisture can gasify, the sack of pulse sack cleaner can not glue the ash caking, and production efficiency is improved, the dioxin index can reach the gas heating device that is used for the shaft kiln flue gas of environmental protection requirement and heats in the flue gas.
The utility model discloses a concrete technical scheme is:
a gas heating device for shaft kiln flue gas heating, includes: the device comprises a flue gas outlet pipe of the shaft kiln, a flue gas inlet pipe of the pulse bag cyclone dust collector, a heating furnace body with an open right end and communicated with the flue gas inlet pipe of the pulse bag cyclone dust collector, a mounting seat penetrating through the left end wall of the heating furnace body and connected with the left end wall, a gas burner arranged at the left end of the mounting seat, a plurality of adjustable air doors and a wind blocking ring connected with the right end of the mounting seat; and an air inlet pipe communicated with a flue gas outlet pipe of the shaft kiln is arranged on one side wall of the heating furnace body.
Preferably, the cross section of the inner cavity of the heating furnace body is circular; the sectional area of the air inlet pipe is smaller than that of the inner cavity of the heating furnace body.
Preferably, the air inlet pipe is positioned at the left end of one side end of the warming furnace body.
Preferably, the number of the adjustable dampers is three; one adjustable air door is positioned on the upper side of the gas burner, and the other two adjustable air doors are symmetrically arranged on two sides of the gas burner.
Compared with the prior art, the beneficial effects of the utility model are that: according to the gas heating device for heating the flue gas of the shaft kiln, the flue gas enters the heating furnace body from the flue gas outlet pipe of the shaft kiln through the inlet pipe, the flame sprayed by the gas burner heats the flue gas to enable the temperature of the flue gas to rise to be higher than 100 ℃, water can be gasified, the flue gas enters the pulse bag cyclone dust collector from the right end of the heating furnace body through the flue gas inlet pipe of the pulse bag cyclone dust collector to be subjected to dust removal, a bag of the pulse bag cyclone dust collector cannot be stuck with ash and agglomerated, the production efficiency is improved, and the dioxin index in the flue gas can meet the environmental protection requirement; the wind-shield ring is beneficial to reducing the influence of the flowing of the flue gas on the flame-throwing port of the gas burner. The sectional area of the air inlet pipe is smaller than that of the inner cavity of the heating furnace body, so that the flow speed of the flue gas entering the heating furnace body is reduced, and the heating is facilitated.
