Abstract
The utility model discloses an air supply device for an alkali recovery furnace. The air supply device for the alkali recovery furnace comprises an air preheater, wherein an air inlet end of the air preheater is communicated with an air inlet pipe connected with a fan; and an air outlet end of the air preheater is communicated with an air outlet pipe connected with the alkali recovery furnace. The air supply device further comprises an air supply branch pipe, wherein the air supply branch pipe and the air preheater are arranged in parallel; one end of the air supply branch pipe is communicated with the air inlet pipe; and the other end of the air supply branch pipe is communicated with the air outlet pipe. The air supply device with the structure has the advantages of simple structure and smooth and sufficient air supply.
Description
Technical field
The utility model relates to a kind of air supply device, is specifically related to a kind of device to the alkali recovery furnace air feed.
Background technology
In the paper-making process, contain a large amount of alkali in the waste liquid that soda pulping process produces, need alkali be recycled, to economize on resources and to reduce environmental pollution.Waste liquid gets into alkali recovery furnace after concentrating, at high temperature, remove the string that is mixed in wherein through the method for burning.In order to keep higher furnace temperature, usually to the alkali recovery furnace hot wind supply.Existing air supply device comprises air preheater, and the inlet end of air preheater is communicated with the blast pipe that is connected with blower fan, and the outlet side of air preheater is communicated with the discharge pipe that is connected with alkali recovery furnace.The air supply device of said structure is because of being serially connected with air preheater on its air feed path, and the heat-exchange tube of air preheater causes air and stops, causes wind supply quantity to be restricted, and that is to say that air feed is not smooth.
The utility model content
The technical problem that the utility model will solve is the air supply device that the alkali recovery furnace of simple in structure, the smooth abundance of air feed is provided to above-mentioned defective.
In order to solve the problems of the technologies described above; The utility model provides a kind of air supply device of alkali recovery furnace of following structure, comprises air preheater, and the inlet end of air preheater is communicated with the blast pipe that is connected with blower fan; The outlet side of air preheater is communicated with the discharge pipe that is connected with alkali recovery furnace; Its design feature is that air supply device also comprises the air feed arm of parallelly connected setting with air preheater, and an end of air feed arm is communicated with blast pipe, and the other end of air feed arm is communicated with discharge pipe.
Be serially connected with valve on the said air feed arm.
Said air preheater is the steam-type air preheater.
The air supply device of the alkali recovery furnace that the utility model provided has only increased the air feed arm of parallelly connected setting with air preheater on the basis of existing air supply device, just can realize goal of the invention, thereby simple in structure.The setting of air feed arm has not only strengthened wind supply quantity; Under the drainage of air feed arm; Liquidated the heat-exchange tube of air preheater to the resistance that air causes, made air become smooth more, thereby realized the smooth sufficient goal of the invention of air feed through air preheater.
In sum, the utlity model has advantage simple in structure, the smooth abundance of air feed.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done further to specify:
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The air supply device of alkali recovery furnace as shown in Figure 1; Comprise air preheater 1; The inlet end of air preheater 1 is communicated with the blast pipe 2 that is connected with blower fan, and the outlet side of air preheater 1 is communicated with the discharge pipe 3 that is connected with alkali recovery furnace, and air supply device also comprises the air feed arm 4 with air preheater 1 parallelly connected setting; One end of air feed arm 4 is communicated with blast pipe 2, and the other end of air feed arm 4 is communicated with discharge pipe 3.Be serially connected with valve 5 on the air feed arm 4, valve 5 is used for regulating the size of air feed arm 4 throughputs.Said air preheater 1 can adopt the air preheater of steam-type air preheater, electrothermal air preheater or other mode of heating; Shown in the figure is the steam-type air preheater; The air preheater of the sort of form no matter, its structure is the known technology of this area, repeats no more at this.
