Problems solved by technology

[0003] Due to the high moisture content and high dust concentration of the dryer tail gas in the production of organic fertilizers, and the organic fertilizer dust is easy to absorb moisture, has high moisture content and high viscosity, it is easy to cause a relatively firm blockage when passing through the filter bag of the bag filter, and the filter Bag cleanup is very difficult
[0004] At present, the mainstream method of organic fertilizer production enterprises to solve the above problems is to first remove the large particles of dust through the cyclone dust collector, and then perform bag dust removal to reduce the pressure of filter bag cleaning, but it is still difficult to solve the dust caused by the high humidity and high viscosity of the dust. The problems of dew condensation bag and filter bag mesh clogging restrict the application of bag filter in the field of organic fertilizer production

Embodiment Construction

[0019] Such as figure 1 , The embodiment of the present invention includes a primary cyclone dust collector 1 and a secondary cyclone dust collector 5, and a dust inlet pipe 2 is installed on one side of the upper end of the primary cyclone dust collector 1. One side of the lower end of the cylinder section of the secondary cyclone dust collector 5 is connected to the upper end of the first-stage cyclone dust collector 1 through the first transition pipe 3, and the end of the first transition pipe 3 connected to the first-stage cyclone dust collector 1 goes deep into a The height inside the cyclone dust collector 1 and lower than the inlet end of the dust inlet pipe 2.

[0020] The organic fertilizer drying dust first enters the first-level cyclone dust collector 1 through the dust inlet pipe 2 for first-level dust removal. Drop about 60-70% of the dust.

[0021] The upper port of the secondary cyclone dust collector 5 is connected to the dust inlet end of the bag filter 13 ...

Abstract

The invention relates to a dust removal and comprehensive utilization system special for an organic fertilizer production line. The system comprises a primary cyclone dust collector, a secondary cyclone dust collector and a bag-type dust collector. An annular water cavity is formed in the outer side of the secondary cyclone dust collector cylinder section, a spiral water vapor guide plate with aninterlayer water channel is installed on the inner wall, a cold water inlet pipe is connected to the upper end opening of the interlayer water channel of the spiral water vapor guide plate, and a guide plate water outlet pipe is connected with a steam boiler; and heating steam coils are fixedly mounted on the outer side surfaces of an ash bucket and a tank body of the bag-type dust collector and are used for transferring heat into the bag-type dust collector. Aiming at high-humidity and high-viscosity dusty organic fertilizer dust, the technical measures of reducing the moisture content, increasing the temperature of dusty gas and the like are adopted, so that dust condensation and bag pasting can be avoided as much as possible, and long-term reliable and stable operation of the bag-type dust collector under actual working conditions is guaranteed; in addition, low-concentration clean organic fertilizer liquid is obtained from an organic fertilizer dust treatment link, and comprehensive utilization of dust is achieved.

Description

technical field [0001] The invention relates to a dust removal and comprehensive utilization system applied to an organic fertilizer production line. Background technique [0002] The filter bag of the bag filter can block the passage of fine dust. The holes interwoven by the warp and weft threads of the fabric are small, while the warp and weft lines themselves are thin, which increases the effective area of ​​screening and reduces wind resistance; in addition, the fluff of the filter bag fabric is long and It is elastic, so that it can cover the holes and has a certain strength; at the same time, because the fluff of the fabric is located on the side where the dusty air contacts, it is easy to clean with reverse air flow, so the exhaust gas treatment system of organic fertilizer production generally adopts bag dust removal device. The dust removal efficiency of the bag filter can reach about 99%. [0003] Due to the high moisture content and high dust concentration of th...
