Description

Anti-hardening honeycomb type bag-type dust remover structure for fertilizer dust and dust removing process Technical Field The invention relates to the technical field of dust collectors, in particular to a hardening-preventing honeycomb type bag-type dust collector structure for chemical fertilizer dust and a dust collection process. Background In the field of fertilizer production, the bag-type dust collector is key equipment for guaranteeing production continuity, standard emission and resource recovery, and has an irreplaceable function. Firstly, it effectively solves the pollution problem of high concentration dust in fertilizer production. In the production of urea, ammonium phosphate or compound fertilizer, a great amount of dust is produced during the granulation, drying, cooling and packaging processes. The bag-type dust collector can collect extremely fine powder particles by virtue of excellent dust collection efficiency, ensures that the exhaust emission strictly meets the national environmental protection standard, and realizes green sustainable development for power-assisted enterprises. And secondly, the bag-type dust collector remarkably improves the product quality and the economic benefit. Dust in fertilizer production is often a valuable raw material. The fine powder recovered by the dust remover can be directly returned to the production system for re-granulation, so that the raw material loss is reduced, the production cost is reduced, the material balance of the production system is maintained, and the product yield is improved. The conventional bag-type dust collector is widely applied in the field of fertilizer production, but has a plurality of non-negligible problems due to the limitations of the structure and the working principle. Fertilizer dust is generally very hygroscopic and adherent. In the production process of urea, compound fertilizer and the like, the tail gas often contains dust and also carries a small amount of ammonia gas or water vapor. Once the temperature of the gas is reduced below the dew point, or the moisture is absorbed by the fertilizer dust and dissolved and becomes sticky due to dew condensation caused by improper heat preservation in the box body of the dust remover. These sticky particles are very prone to clog the pores of the filter bag and harden gradually under repeated blowing to form a hard-to-peel plate-like layer. The negative effects of dust hardening are quite significant. On one hand, the hardening layer greatly increases the filtering resistance, so that the air quantity processed by the system is reduced sharply, the energy consumption of the fan is increased, and even the production line is forced to run with load reduction when serious. On the other hand, in the other hand, the sticking of the bag may result in a loss of air permeability of the filter bag, the ash removal effect fails. In addition, the fertilizer dust contains chemical components, and long-term hardening can corrode filter bag fibers, so that the service life of the filter bag fibers is shortened. Disclosure of Invention In view of the problem that dust hardening easily occurs in the dust remover in the prior art, the structure of the anti-hardening honeycomb type bag-type dust remover for chemical fertilizer dust is provided. The dust remover aims to enable the dust remover to strip hardened dust and ensure the filtering effect. The technical scheme of the invention is that the anti-hardening honeycomb type bag-type dust remover structure for fertilizer dust comprises a machine case and a cleaning mechanism arranged in the machine case; The cleaning mechanism comprises a plurality of fixing rings arranged on the chassis partition plate, filter bags arranged at the edges of the bottoms of the fixing rings, vertical rods arranged at the centers of the bottoms of the fixing rings, a plurality of annular arrays arranged on the support at the top of the side wall of the vertical rods, elastic rods arranged on one side of the support away from the vertical rods, pull rings arranged at the middle parts of the elastic rods, lifting holes arranged inside the vertical rods, lifting rods arranged on the inner walls of the lifting holes, bending rods arranged at the bottoms of the lifting rods, connecting frames I arranged at the tops of the lifting rods together, hydraulic rods I arranged at the tops of the connecting frames I, and torsion units arranged on the inner walls of the lifting rods.

Further, a bayonet is formed in one side, close to the bent rod, of the pull ring, and the diameter of the bent part in the middle of the bent rod is smaller than that of the bayonet. Further, the bottom annular array of lifter is provided wi
