Abstract

The utility model relates to a mixture heat value stabilizer, comprising a cylinder shell which is connected with a mixture outlet smaller than the shell through a conical connecting. A blast furnace gas pipe joint which is closed by an end-plate with the shell is arranged at the inner of the shell. A cone export is arranged at the internal end of the blast furnace gas pipe joint. The shell is also provided with a coke-oven gas pipe joint. The utility model adopts flow injection principle, the imported coke-oven gas increases correspondingly when pressure of the blast furnace gas increases, conversely, decreases correspondingly, so stabilization of the mixture heat value is realized.

Description

The heat vale of mixture stabilizer
Technical field
The utility model relates to the calorific value stabilizer that a kind of mixture combustion is used.
Background technology
Because the blast furnace gas calorific capacity is low, is applied to kiln production separately, is difficult to reach temperature required requirement, need to mix use with the coke-stove gas of high heating value.Existing blast furnace, coke-stove gas mix the station, because mixing apparatus is simple, design unreasonablely, and when blast furnace gas pressure was high, the amount of participating in of coke-stove gas diminished on the contrary; Otherwise when blast furnace gas pressure was low, the amount of participating in of coke-stove gas can increase.Thereby cause mixed gas calorific value to change the variation that produces in a big way, make its blast wandering, operating difficulties, weak effect with the pressure of blast furnace gas.
Summary of the invention
The purpose of this utility model is that a kind of heat vale of mixture stabilizer that can use two kinds of gas-fireds smoothly will be provided.
Utility model has been achieved in that a barrel shrond, and by the taper joint mixed gas outlet pipe little than shell of ining succession, shell is built-in with a blast furnace gas pipe joint, and with the shell end plate closes, there is conical outlet blast furnace gas pipe joint the inner.On shell, also connecting a coke-stove gas pipe joint.
The utility model utilizes the air-flow ejector principle, when blast furnace gas pressure increases, and the also corresponding increase of the coke-stove gas amount of bringing into, on the contrary corresponding attenuating can be played the stabilization of heat vale of mixture.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Introduce the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing, the barrel shrond 5 that diameter is 1200mm connects the taper joint 2 of one 60 degree, and its microcephaly connects the mixed gas outlet pipe 1 that diameter is 800mm.The blast furnace gas pipe joint 7 that in the shell 5 diameter to be arranged be 600mm is with 6 sealings of shell 5 usefulness end plates.There are 60 degree conical outlets 3 blast furnace gas pipe joint 7 the inners.On shell 5, the coke-stove gas pipe joint 4 that also vertically to connect a diameter be 500mm.

Claims (1)

1, a kind of heat vale of mixture stabilizer, it is characterized in that: a barrel shrond (5) is arranged, by taper joint (2) the mixed gas outlet pipe (1) little of ining succession than shell, shell (5) is built-in with a blast furnace gas pipe joint (7), seal with end plate (6) with shell, there is conical outlet (3) blast furnace gas pipe joint (7) the inner, is also connecting a coke-stove gas pipe joint (4) on shell (5).
