2React the realization desulfuration in furnace.This device mainly is made of material-transporting system and air-transport system, material-transporting system mainly comprises two storage tank, screw(-type) feeder and the jet pumps vertically installed, the inside of these two storage tanks is connected, a feed bin (ash-storing bin) is installed in the upper end of last storage tank, the discharging opening place of following storage tank connects screw(-type) feeder, the outlet of screw(-type) feeder connects jet pump, and jet pump is connected with air-transport system.Owing on the last storage tank high-order material meter and dome inlet valve have been installed, low level material meter and dome inlet valve have been installed on the following storage tank, therefore under the effect of high position material meter, low level material meter and two dome inlet valves, agstone through feed bin, storage tank, screw(-type) feeder and jet pump after, can be injected under the effect of air-transport system advance in the boiler and carry out desulfurization.
In use there is following defective in this desulfurizer: 1, owing to not having the installation material material level to put supervising device on the storage tank down, need lean on time control the closing and opening of dome inlet valve of storage tank down when adopting two jars of chargings, therefore the control point is many, control accuracy is low, causes easily that the feeding error is big, transfer efficiency is low; 2, owing to the storage tanks that adopt two vertically to install, so the equipment whole height is higher, and it is bigger to take up room, and during installation factory building is had relatively high expectations, and is not suitable for installing and using in highly shorter occasion; 3,, cause and install and the equal inconvenience of maintenance because material-transporting system and connected feed bin height are higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, can reduce the equipment whole height, makes things convenient for installation and maintenance, and charging precision height can improve the lime stone in-furnace calcium spraying flue gas desulfur device of agstone transfer efficiency.
The utility model solves its technical problem and is achieved through the following technical solutions:
A kind of lime stone in-furnace calcium spraying flue gas desulfur device, comprise material-transporting system and air-transport system, material-transporting system comprises screw(-type) feeder, jet pump and the storage tank that is connected with feed bin, it is characterized in that: the storage tank in the material-transporting system is one, high-order material meter and dome inlet valve are installed in the top of this storage tank, dome inlet valve top connects feed bin, and low level material meter is installed in the bottom of storage tank, and the discharging opening of storage tank connects screw(-type) feeder and jet pump successively; The top of storage tank is communicated with a balance pipe that vertically is provided with by a tube connector, the upper end of this balance pipe connects feed bin, the lower end connects screw(-type) feeder, in that balanced valve on is installed on the balance pipe between feed bin and the tube connector, balanced valve once is installed on the balance pipe between screw(-type) feeder and the tube connector.
And described air-transport system comprises roots blower and conveyance conduit.
And described screw(-type) feeder is quantitative screw(-type) feeder.
Advantage of the present utility model and beneficial effect are:
1, the storage tank in this desulfurizer has only one, high-order material meter and the score of low level material are not installed in the upper and lower of storage tank, therefore high and low position material meter can be monitored constantly to the height of materials in the tank body, guarantee the accuracy of charging, reduce the error of charging, improve the transfer efficiency of material.
2, single jar of charging in this desulfurizer is that the pressure in the storage tank is discharged charging again from balance pipe earlier, because screw(-type) feeder can be sealed the pressure in the conveying, so to carrying not influence, solved the problem that the decompression influence is carried in carrying.Reduced though this device is compared equipment with legacy equipment, still can reach same desulfurization and dedusting effect, and production cost is significantly reduced.
3, the material-transporting system of this desulfurizer makes single jar structure into by two jar structures of vertical setting, makes the whole height of this device greatly reduce, and the factory building height limited degree reduces, and has increased the scope of application of this device.
4, after this desulfurizer whole height reduces, not only be convenient to the equipment installation and maintenance, and make feed bin arrangement convenience in the boiler room.
5, the utility model is a kind of reasonable in design, simple in structure, installation and maintenance lime stone in-furnace calcium spraying flue gas desulfur devices easily, this device adopts single jar of feeding manner, has improved the charging precision, has reduced and produced the effect that drops into and can reach the charging of traditional double jar equally.
