Description

Novel desulfurization reaction tank convenient to change catalyst

The technical field is as follows:

the utility model relates to a coal coking production technical field, concretely relates to novel desulfurization reaction tank convenient to change catalyst.

Background art:

in coal chemical industry technical field, the dry desulfurization generally adopts the desulfurization reaction tank, the general structure of desulfurization reaction tank includes the desulfurization cell body of vertical setting, install fixed grid in the desulfurization cell body, be equipped with the zinc oxide catalyst between the fixed grid, though dry desulfurization purification degree is high, nevertheless become invalid after the catalyst in this kind of desulfurization reaction tank uses for a long time, need the periodic replacement, generally carry out whole changes and intensity of labour is big when changing the catalyst among the prior art, it takes time and time, under the normal condition, gaseous follow the top and get into behind the desulfurization and discharge, consequently, the desulfurizer that exists and be located upper portion has become invalid and the desulfurizer of bottom still has fine activity, if change easily and certainly can lead to the wasting of resources, lead to catalyst consumption too big, and production cost is too high.

The utility model has the following contents:

an object of the utility model is to provide a novel desulfurization reaction tank convenient to change catalyst.

The content of the utility model is as follows: a novel desulfurization reaction tank convenient for catalyst replacement comprises a vertically arranged square desulfurization tank body, wherein an air inlet pipe and an air outlet pipe are respectively arranged at the top end and the bottom end of the desulfurization tank body, a plurality of sieve plate layers are uniformly fixed in the desulfurization tank body from top to bottom, a plurality of slide rails are uniformly fixed on each sieve plate layer from left to right, a plurality of catalyst storage tanks are sequentially arranged on each slide rail from front to back, air holes are fully distributed on the bottom plate of each catalyst storage tank, a slide block is arranged at the bottom end of each catalyst storage tank and is in sliding connection with the slide rails, clamping grooves and clamping blocks are respectively arranged at the front side and the rear side of each catalyst storage tank, the clamping blocks are clamped in the clamping grooves of the adjacent catalyst storage tanks, and a replacement window is arranged on the outer wall of the desulfurization tank body, the outer edge of the replacing window is provided with a sealing ring groove, a sealing ring is installed in the sealing ring groove, one side of the replacing window is hinged with a sealing cover plate, and the other end of the sealing cover plate is fixedly connected with the desulfurization groove body through a bolt.

The utility model has the advantages that: the utility model discloses simple structure designs the sieve layer that the multilayer supplied the catalyst to deposit in desulfurization cell body to the design is the catalyst storage tank that "cell" form distributes, through slide rail sliding connection between storage tank and the sieve layer, not only can realize that the catalyst layering is changed, practices thrift catalyst resources, reduction in production cost, and catalyst change convenient and fast more moreover, labour saving and time saving, work efficiency is high.

Description of the drawings:

fig. 1 is a perspective view of the present invention;

FIG. 2 is a distribution structure diagram of the sieve plate layer of the present invention;

FIG. 3 is an enlarged view of part A of FIG. 2;

FIG. 4 is a distribution structure diagram of the catalyst storage tank of the present invention;

in the figure, a desulfurization tank body 1, an air inlet pipe 2, an air outlet pipe 3, a sieve plate layer 4, a slide rail 5, a catalyst storage tank 6, an air vent 7, a slide block 8, a clamping block 9, a replacement window 10, a sealing ring groove 11, a sealing cover plate 12 and a clamping groove 13.

The specific implementation mode is as follows:

as shown in fig. 1 to 4, a novel desulfurization reaction tank convenient for catalyst replacement comprises a vertically arranged square desulfurization tank body 1, an air inlet pipe 2 and an air outlet pipe 3 are respectively arranged at the top end and the bottom end of the desulfurization tank body 1, a plurality of sieve plate layers 4 are uniformly fixed in the desulfurization tank body 1 from top to bottom, a plurality of slide rails 5 are uniformly fixed on each sieve plate layer 4 from left to right, a plurality of catalyst storage tanks 6 are sequentially arranged on each slide rail 5 from front to back, vent holes 7 are fully distributed on the bottom plate of each catalyst storage tank 6, a slide block 8 is arranged at the bottom end of each catalyst storage tank 6, the slide block 8 is slidably connected with the slide rails 5, clamping grooves 13 and clamping blocks 9 are respectively arranged at the front side and the back side of each catalyst storage tank 6, and the clamping blocks 9 are clamped in the clamping grooves 13 of the adjacent catalyst storage tanks 6, it has change window 10 to open on the outer wall of desulfurization cell body 1 the outer fringe of changing window 10 is opened has sealed annular 11 install the sealing washer in the sealed annular 11 one side of changing window 10 articulates there is sealed apron 12, the other end of sealed apron 12 pass through the bolt with desulfurization cell body 1 fixed connection.

The working principle is as follows: the during operation, treat that the gas that purifies enters into desulfurization cell body 1 from intake pipe 2 in, discharge by outlet duct 3 after the catalyst carries out the desulfurization in catalyst storage tank 6, when needing to change the catalyst after long-time the use, can unscrew the bolt and open sealed apron 12, then with the catalyst storage tank 6 pull out the change on corresponding layer can.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
