Abstract
The utility model provides a fixed layer intermittent mixing gas making device. Inlets of upper coal gas recovery pipelines of a gas making furnace are inserted in a dry distillation layer inside a hearth; and pipeline wall cracks are arranged on the upper coal gas recovery pipelines and communicated with a blast pipeline at the bottom of the gas making furnace through a secondary air supplementary valve. A plurality of upper coal gas recovery pipelines are arranged on the gas making furnace. Secondary air can be supplemented for the dry distillation layer inside the hearth during the blowing stage; the partial afterheat of fume is also recovered while the pipelines are safely protected, and the thickness of the dry distillation layer is increased under the situation of maintaining the thickness of a normal gasifying layer, so that more heat is stored for blowing gas. The inlets of the coal gas recovery pipelines are inserted in the dry distillation layer inside the hearth, which is considered from angles of smooth transition of upper coal gas transmission and upper coal gas recovery; and when upper coal gas is recovered, the system resistance can not be increased.
Description
Technical field
The utility model relates to a kind of immovable bed mixed device of air at intermittence in the fixed bed producer at intermittence.
Background technology
At present, the uplink and downlink coal gas landline of intermittent gasification of fixed layer stove is, after up coal gas and descending coal gas come out from producer, all passing through the water seal valve enters gas main and sends into back workshop section and handle, the steam utilization of this conventional operation mode is about 40%, water-gas contains tar, organism is more, and it is big to cause back workshop section to handle load.Chinese patent 200420011259.8 discloses intermittently producer of a kind of twin bituminous coal fixed bed, promptly the up gas pipe that will be communicated with two essentially identical producers of structure by the connection pipe is communicated with, following steam blowing pipe and smoke exhaust pipe are communicated with the connection pipe, the descending gas pipe of two-way is communicated with two furnace bottoms respectively, last steam blowing pipe is told the two-way pipeline, be communicated with two furnace bottoms respectively, blast main is told the two-way pipeline, be communicated with two furnace bottoms respectively, add the nitrogen blast main and tell the two-way pipeline, be communicated with two furnace bottoms respectively, last steam blowing pipe and following steam blowing pipe are communicated with steam manifold, descending gas pipe with the back operation thermal utilization equipment be communicated with, blast main is communicated with air main.This device has been realized at normal system gas during the stage, the conveying of classifying of uplink and downlink coal gas, up coal gas is gone into stove and is reclaimed, descending coal gas is sent into back workshop section and is handled, not only reduced investment, saved cost, and the plugging that brings of the tar, organism and the dust that generate when having solved raw material, reduced a series of problems such as catalyst activity for bituminous coal.But but do not consider air blowing problem and heat recuperation problem.
Summary of the invention
Technical problem to be solved in the utility model provides intermittently mixed device of air of a kind of immovable bed, can solve air blowing problem and heat recuperation problem on the basis of normal system gas stage classification conveying uplink and downlink coal gas.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of immovable bed is mixed device of air intermittently, the top of the essentially identical producer of two or more structures is communicated with up coal-gas recovering house steward by up coal-gas recovering pipeline, the up coal-gas recovering pipeline import of each producer is inserted in the destructive distillation layer of burner hearth inside, up coal-gas recovering pipeline is provided with the duct wall crack, and the duct wall crack is connected with producer pucking airduct road by the secondary air replenishment valve.The up coal-gas recovering pipeline of each producer has many.
A kind of immovable bed provided by the utility model is mixed device of air intermittently; owing to adopted above-mentioned scheme; can replenish secondary air by the destructive distillation layer to burner hearth inside by secondary air replenishment valve and duct wall crack in the blowing stage; in the protection pipeline safety, also reclaimed the part of waste heat of flue gas; under the situation of safeguarding normal gasification layer thickness; increased the thickness of destructive distillation layer, under blow gas and laid in more heat.The import of coal-gas recovering pipeline is inserted among the destructive distillation layer of burner hearth inside, and this is that up coal gas is carried and the smooth transition angle of up coal-gas recovering considers that when carrying out up coal-gas recovering, systemic resistance can not increase from carrying out.
In the normal system gas stage, can carry out the transition of up coal gas conveying and up coal-gas recovering stably, when moving up coal-gas recovering pipeline, close up coal gas export pipeline, make some or all of up coal gas enter the coal-gas recovering house steward, under blow the stage, utilize the coal gas of deposit in the coal-gas recovering house steward to make vaporized chemical, go into stove system gas with steam blowing down.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is an one-piece construction synoptic diagram of the present utility model.
Fig. 2 is the utility model device partial top view.
Embodiment
A kind of immovable bed is mixed device of air intermittently, the top of the essentially identical producer of two or more structures is communicated with up coal-gas recovering house steward 3 by up coal-gas recovering pipeline 6, up coal-gas recovering pipeline 6 imports of each producer are inserted in the destructive distillation layer of burner hearth inside, up coal-gas recovering pipeline 6 is provided with duct wall crack 7, duct wall crack 7 is connected with producer pucking airduct road 10 by secondary air replenishment valve 1,4.The up coal-gas recovering pipeline 6 of each producer has many.
As shown in Figure 1, 2, three up coal-gas recovering pipes 6 are inserted among the destructive distillation layer of burner hearth inside, in the normal system gas stage, during 8 operations of A producer, 2 operations of A producer gas recovery valve, during 9 operations of B producer, 5 operations of B producer gas recovery valve, reclaim, blow on once, blow on the secondary and blow off the stage in blowing, up coal gas is delivered into coal-gas recovering house steward 3 by A producer gas recovery valve 2 and B producer gas recovery valve 5 are some or all of, under blow the stage, the coal gas of deposit among coal-gas recovering house stewards 3 is made vaporized chemical, go into stove system gas with time steam blowing; In the blowing stage; during 8 operations of A producer; air in the blowing line 10 through the duct wall crack 7 of A stove secondary air replenishment valve 1 by up coal-gas recovering pipeline 6 to the additional secondary air of the destructive distillation layer of burner hearth inside; during 9 operations of B producer; air in the blowing line 10 through the duct wall crack 7 of B stove secondary air replenishment valve 4 by up coal-gas recovering pipeline 6 to the additional secondary air of the destructive distillation layer of burner hearth inside; thereby protection pipeline safety; reclaim the flue gas part of waste heat; increase the thickness of destructive distillation layer, under blow gas deposit more heat.
