Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model ammonium salt drying system.

Specific embodiment

The utility model is described in detail with reference to the accompanying drawings and examples, but the utility model is not by embodiment Any restrictions.

As shown in Figure 1, a kind of ammonium salt drying system of the utility model, including the pressurization of anticaking agent adding tube, instrument supply gas Pipe, wet ammonium blanking device, crusher, feeder, dry ammonium furnace and dust arrester installation, the anticaking agent adding tube and the instrument supply gas Pressure inlet is connected with the wet ammonium blanking device respectively, and the crusher is connected with the wet ammonium blanking device, described broken Broken machine and the dry ammonium furnace are connected with the feeder respectively, and the dust arrester installation is connected with the dry ammonium furnace.

In the above-described embodiments, to reduce water content when wet ammonium blanking, the wet ammonium blanking device is preferably centrifuge. To be sufficiently mixed anticaking agent in time with wet ammonium, it is preferable that the anticaking agent adding tube and the instrument supply gas pressure inlet It opens and closes while carrying out, the anticaking agent adding tube adds anticaking agent in such a way that instrument supply gas is distributed.To make raw material Granularity meets connection alkali production requirement, promotes correlated response uniformly to carry out, to provide safeguard for product quality, to added with anti-caking The wet ammonium further progress of agent is broken and stirs, and is carried out by the crusher, i.e., the described crusher is wet for being crushed and stirring Ammonium material is preferably provided with motor, main shaft and blade on the crusher, and the main shaft is driven by motor, and the blade has multiple groups, The blade ring is arranged around the main shaft, when the crusher is run, by motor driven main shaft, to drive each blade high speed Rotation, wet ammonium material enters wet ammonium when crusher and closely rubs and each blade of strong Ground shock waves in swirling eddy, to wet ammonium It is sufficiently crushed and is stirred, thus effectively change wet ammonium granularity, the granularity energy through the broken wet ammonium material of the crusher Enough it can make to reach through the granularity of the broken wet ammonium material of the crusher by adjusting the revolving speed of motor for 1mm~4mm 1mm~3mm.For effectively avoid occurring agglomerating on fluidized bed and be induced by it phenomena such as mounting the throne, it is preferable that the charging Device is the device fed using the mode of shedding.The dry ammonium furnace includes furnace body and the feed inlet being arranged on the furnace body and discharging Mouthful, the furnace body is preferably ellipse, to reduce heat loss, the thermal efficiency is improved, to improve dry ammonium efficiency；Preferably, institute It states and is provided with blender at the feed inlet of dry ammonium furnace, the wet ammonium material for entering fluidized bed is stirred, to avoid agglomerating and sit Bed and dead bed provide further ensure；Preferably, the discharge outlet in the dry ammonium furnace is provided with bed height regulating valve, make Bed keeps preferably height, to improve operating efficiency.To enhance environment protecting, the dust generated during dry ammonium is carried out It is effectively treated, it is preferable that the dust arrester installation includes the multiple groups cyclone dust collectors and dust collecting installation being connected, described in each group Cyclone dust collectors are connected with the dry ammonium furnace respectively.

More preferably ammonium salt raw material can be provided for connection alkali production using the utility model ammonium salt drying system, specifically, When the wet ammonium blanking device carries out wet ammonium blanking, anticaking agent is added by the anticaking agent adding tube, anti-caking is being added Supercharging air is carried out using the instrument supply gas pressure inlet when block agent, anticaking agent is made uniformly to be sprayed at wet ammonium table with atomised form Face prevents wet ammonium part caused by adding unevenness because of anticaking agent from agglomerating；It will be in the wet ammonium blanking device by the crusher In the wet ammonium of false agglomeration break increase contact area, while the wet ammonium of anticaking agent will be added to stir evenly, to guarantee wet Ammonium enter fluidized bed when granularity between 1-3mm；Broken wet ammonium is entered by the feeder using the mode of shedding Dry ammonium furnace, such parabolic, which enters furnace mode and can effectively ensure that, is uniformly distributed effect when wet ammonium enters furnace laggard fluidized bed, from And increase the vulcanization bed cycle of operation, effectively avoid feeding because of wet ammonium it is uneven caused by fluidized bed mount the throne dead bed；Wet ammonium after entering furnace It is dried in the dry ammonium furnace of fluidized bed, the dust generated in drying process is handled by dust arrester installation, ensures environmental protection.? When concrete application the utility model, the bases such as involved wet ammonium water content, anticaking agent additive amount, anticaking agent and dilution water ratio Specific operating condition determines, it is preferable that anticaking agent additive amount is that 0.2~0.4kg, anticaking agent and dilution water ratio is added in ammonium per ton For 1:3~1:6, wet ammonium water content is 5~8%.

Generally, since the moisture that wet ammonium is included is mainly existing capillary between wet ammonium particle surface moisture, particle Pipe moisture, these moisture are all unbound water, so, in the drying process of the unbound water of wet ammonium surface of material, wet ammonium table The vapour pressure in face is equal with the synthermal vapour pressure being lauched, and by the surface vaporization speed control rate of drying of water, changes wet ammonium grain Diameter increases wet ammonium surface area, facilitates moisture evaporation, and then increase dry ammonium furnace production capacity.By changing using the utility model It gets wet ammonium partial size and adjusts wet ammonium feeding manner, enhance the cloth wind effect of dry ammonium furnace fluidized bed, to effectively solve wet ammonium band block Into dry ammonium furnace, enter to be not easy after furnace dispersion, in a fluidized bed cloth it is uneven and generate agglomeration, mount the throne and the problems such as dead bed, into And solve the problems, such as that the dry ammonium furnace cycle of operation is short, manipulation strength is big, guarantee the stable operation of dry ammonium furnace, be greatly reduced it is economical at This；Meanwhile more preferably ammonium salt raw material is provided for connection alkali production, the quality for producing product for connection alkali provides safeguard, and is conducive to increase warp Ji benefit, is suitble to industrial application.

The present invention is not limited to the above embodiments, and those skilled in the art are made any to above embodiment Conspicuous improvement or change, all protection scope without departing from the design of the utility model and appended claims.
