Abstract
The utility model discloses a tower granulation is chain governing system of temperature for mixing tank relates to tower granulation equipment, solves the problem that mixing tank that tower granulation exists was blasted easily. A tower granulation is chain governing system of temperature for mixing tank, the mixing tank body that has the steam pipework including the intercommunication, be equipped with the steam control valve on the steam pipework, still include the desalination water tank, underground tank, and temperature controller, the pipeline and desalination water tank intercommunication of mixing tank body through being equipped with desalination water tank control valve, through the pipeline and underground tank intercommunication that is equipped with the underground tank control valve, temperature controller is by installing in this internal forming with built -in upper limit warning contact with temperature sensor of mixing tank, upper limit warning contact respectively with desalination water tank control valve, the underground tank control valve, steam control valve bond. The utility model discloses the temperature detects sensitive accuracy, and the emergence that can prevent and stop equipment and personal safety accident promotes product quality stable, reduces intensity of labour, improves production efficiency.
Description
Technical field
This utility model relates to nitro-compound fertilizer high-tower granulation equipment, is specifically related to a kind of nitro-compound fertilizer chain adjustment system of high-tower granulation mixing channel temperature。
Background technology
Nitro-compound fertilizer is with ammonium nitrate for nitrogenous source, adds the compound fertilizer raw material such as phosphorus, potassium, N, P, K high-concentration compound fertilizer material produced, not only containing nitrate nitrogen but also containing ammonium nitrogen, be a kind of high value fertilizer variety in its product, nutritious composition is complete, widely applicable, the advantages such as effective ingredient loss is few。
The production method of nitro-compound fertilizer mainly has high-tower granulation method, Nitro Phosphate Unit method and nitrophosphate fertilizer secondary operations method。Wherein high-tower granulation method have nutrient and granule uniformly, constant product quality, operating cost is low, the advantage of less energy consumption, so popularization and application are extensive, but high-tower granulation method due to ammonium in the mixing channel of prilling section because there is the ammonium nitrate fused solution of high concentration, very easily produce the decomposition of ammonium nitrate when temperature is too high and accident of blasting。
The method of existing solution mixing channel blast is to adopt temperature in groove and add the method for chain adjustment of vapours, namely reach 180 DEG C of stoppings in temperature and add vapours, but actual production still has the accident potential blasted, this is because releasing amount of heat when ammonium nitrate starts to decompose, vapours is added although stopped, but ammonium nitrate is once decomposition, the heat of generation is possible to make temperature in groove continue to raise, thus causing blast。
The above-mentioned mixing channel existed to solve high-tower granulation is susceptible to the problem of blast, and this utility model have developed the chain adjustment system of a kind of temperature suitable in the mixing channel of high-tower granulation。
Summary of the invention
This utility model is the problem that the above-mentioned mixing channel existed to solve high-tower granulation is susceptible to blast, and provides a kind of chain adjustment system of high-tower granulation mixing channel temperature。
This utility model is to be achieved through the following technical solutions:
A kind of chain adjustment system of high-tower granulation mixing channel temperature, including the mixing channel body being communicated with steam pipework, described steam pipework is provided with steam control valve, wherein also include desalination water tank, underground tank, and temperature controller, described mixing channel body controls the pipeline of valve and connects with desalination water tank by being provided with desalination water tank, the pipeline controlling valve by being provided with underground tank connects with underground tank, by being arranged on, mixing channel is intrinsic to be formed described temperature controller with temperature sensor and built-in upper limit alarm contact, described upper limit alarm contact controls valve with desalination water tank respectively, underground tank controls valve, steam control valve connects。
During use, it is arranged on mixing channel intrinsic temperature sensor and temperature can be carried out sensitive and accurate detection, and temperature is passed to temperature controller, when temperature controller detect temperature reach arrange the upper limit time (generally arranging ceiling temperature is 180 DEG C), upper limit alarm contact can control valve with dewatering box moment, underground tank controls valve, steam control valve connects, moment controls dewatering box control valve and opens, to this internal feeding desalted water of mixing channel, control underground tank control valve to open, intrinsic for mixing channel ammonium nitrate fused solution is discharged in underground tank, and moment controls steam control valve and closes, stop adding vapours to this internal input of mixing channel, thus reaching thoroughly to solve the safety problem of mixing channel。
In sum, this utility model temperature detection is sensitive and accurate, can prevent and stop the generation of equipment and personal safety accident, promotes constant product quality, reduces labor intensity, improves production efficiency。
