The invention discloses an organic waste gas purifying system and method for preventing the surface of an absorbing material from condensing and caking. The organic waste gas purifying system comprises an absorption tower, a desorption tower, a conveying device and an absorbing material preheating device, wherein the bottom of the absorption tower is provided with an organic waste gas inlet, the top of the absorption tower is provided with a purifying gas outlet, the inside of the absorption tower is separated into a plurality of layers by using a porous plate; an absorbing material falling from the top end of the desorption tower falls to a desorption heating part through an overflowing part, a desorption gas is introduced from the bottom of the desorption tower to be in contact with the absorbing material so as to desorb an organic gas absorbed in the absorbing material; the conveying device is used for conveying the absorbing material in a desorption tower storage tank to the top end of the desorption tower; and the absorbing material preheating device is arranged at the upstream of the desorption heating part. The organic waste gas purifying method comprises the steps of: additionally providing a preheating procedure before the desorption procedure is carried out; and preheating the absorbing material or/and preheating the organic waste gas in the preheating procedure. The system and method provided by the invention have the effect of preventing the surface of the absorbing material from condensing and caking, and can be used for preventing from incomplete desorption, air tower and blockage of related parts.

The invention provides a scattering device used for powder treatment and a powder scattering machine. The problem about scattering of agglomerated powder, especially large agglomerated powder can be dealt with effectively, and the powder can recover to the original physicochemical property. The scattering device comprises a shell internally provided with an upper cavity and a lower cavity, a scattering motor of which the output end is connected with a rotating shaft through a transmission part, a rotor disc arranged in the shell and installed on the rotating shaft, and a stator part. One or more multifunctional plates are arranged in the rotor disc in the circumferential direction. The stator part comprises tooth plates and screen bars, wherein the tooth plates are distributed on the two sides of the lower cavity, and the screen bars are evenly distributed at the bottom of the lower cavity. The interior of the upper cavity and the interior of the lower cavity are in arc shapes, and theradius of the arc of the lower cavity is larger than the radius of the arc of the upper cavity. The rotor disc is concentric with the circle in the upper cavity, and the rotor disc, the tooth platesand the screen bars in the lower cavity form a non-concentric structure. The clearance between the outer wall of the rotor disc and the inner wall of the shell is gradually reduced from top to bottom,and therefore a gradually-changing type scattering cavity is formed.

The invention discloses a quantitative feeding device for preventing caking of a powdery particulate matter, and the quantitative feeding device is suitable for quantitative feeding of the powdery particulate matter which is easy to cake or in a moistening feeding environment, can effectively prevent the hardening of the powdery particulate matter, and can ensure quantitative feeding of the powdery particulate matter. The feeding device comprises a storage barrel and an anti-caking device; the powdery particulate matter is ground twice to become fine particles, and then quantitatively added toa target container by a quantitative feeding device.

The invention relates to a spiral feeding device. The spiral feeding device comprises a feeding hopper (1), a spiral material passage (2) and an unloader (3) which communicate with one another sequentially. A spiral mechanical mounted in the spiral material passage (2) can convey raw materials from the feeding hopper (1) into the unloader (3), the spiral feeding device further comprises a stirringmechanism (6) used for conducting primary stirring on the raw materials, and the stirring mechanism (6) is mounted in the feeding hopper (1). By mounting the stirring mechanism in the feeding hopper,primary stirring can be conducted on the raw materials, caking of the raw materials is reduced accordingly, and the weighing precision of dosing is improved effectively.

The invention relates to the technical field of rice, and discloses a rice fertilizing device capable of reducing caking and realizing quantitative and uniform scattering. The rice fertilizing device comprises a storage box, the storage box is used for storing chemical fertilizer, a feeding port is formed in the outer side of the storage box, and a sieve plate, the feeding port, a baffle plate and a limiting rod are matched for use, so that quantitative scattering is realized during scattering; vibration screening is carried out before scattering, fertilizer particles are more uniform, meanwhile, waste is prevented from caking to be scattered, and scattering is more uniform; through cooperative use of a rotating shaft, a limiting sleeve and a discharging barrel, the discharging barrel is driven to swing during fertilizer scattering, accordingly, fertilizer scattering is more uniform, and the fertilizer scattering efficiency is improved; and through cooperative use of a second disc, a sleeve rod, a rotating shaft and a limiting sleeve, the two steps of uniformly and quantitatively scattering the fertilizer and vibrating the caked fertilizer are linked, so that the linkage performance of the whole device is improved, and the operation is simpler.
