A zero-pollution vacuum cleaner type catalyst digging and screening device and its application method

Abstract

The invention discloses a pollution-free dust collector-type catalytic agent taking-filling and sieving device, and an application method thereof. The pollution-free dust collector-type catalytic agent taking-filling and sieving device comprise a connecting flexible pipe, a sieving jacket, a draught fan inlet flexible pipe, an induced draft fan, a washing tower, a drawing type cleaning groove, a clear liquid groove, a washing pump, and a power distribution cabinet, and is also provided with a hand pull rod, a fixing button, a suction inlet, a fixing flange, a bagging control valve, a regulating valve, an atomization spray nozzle, an exhaust port, a water adding nozzle, an overflow port, a liquid loading pipe, a reflux valve, a communicating pipe, a liquid drainage nozzle, and a pedestal. According to the application method, the pollution-free dust collector-type catalytic agent taking-filling and sieving device and bagging position are adjusted by operating personnel based on on-site actual position via the connecting flexible pipe; the washing pump and the induced draft fan are turned on successively; a catalytic agent is sieved via the suction inlet, the connecting flexible pipe, and the sieving jacket, and the intact catalytic agent is subjected to bagging using the bagging flange, and then is subjected to backfilling; small particle catalytic agent is delivered into the washing tower for washing via the draught fan, clear liquid is recycled, and dust is delivered into the drawing type cleaning groove. Operation of the pollution-free dust collector-type catalytic agent taking-filling and sieving device is simple; and the pollution-free dust collector-type catalytic agent taking-filling and sieving device is capable of increasing the efficiency of catalytic agent taking and sieving greatly.

Description

technical field technical field [0001] The invention belongs to the technical field of chemical industry, and relates to a device for removing and screening converter catalysts in sulfuric acid production, in particular to a zero-pollution vacuum cleaner type catalyst removing and screening device and its use method. Background technique [0002] After long-term use of the sulfuric acid system conversion catalyst, phenomena such as hardening, poisoning, pulverization, and failure will occur, resulting in a decrease in conversion rate. For this reason, the annual inspection needs to carry out catalyst digging, screening and backfilling. At present, the catalyst removal is purely manual work, that is, after the hot blowing and cold blowing of the converter, the manholes on each layer are opened to cool down naturally. After about 24 hours, the temperature drops to about 45°C. Each layer of the converter uses a shovel to slowly shovel the catalyst into the woven bag, and the...
