Abstract
Description
Technical field
The present invention relates to field of Environment Protection, more particularly, relate to a kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system.
Background technology
Along with the fast development of automobile, boats and ships and telecommunications industry, lead-acid storage battery also develops rapidly as the power source that cost performance is higher thereupon, and practitioner is increasing year by year.Due to personnel's close contact hazardous and noxious substances of lead-acid storage battery production enterprise more than 80%, measure of control imperfection in addition, causes the health of the former operating personnels of objectionable impurities such as contact lead and sulfuric acid to receive serious threat.Thus, to lead-acid storage battery production enterprise implement actv. measure of control, reduce occupational disease attack rate, become the task of top priority of lead-acid storage battery production enterprise occupational health management work.
Mainly there are following problems in existing lead-acid storage battery production:
Lead powder delivery system device is huge, and plant maintenance amount is large, and equipment failure rate is higher, all will carry out the maintenance of lead powder conveyer and part replacement every year, and lead dust is large especially to maintenance of equipment personnel injury.
Summary of the invention
The technical matters that the present invention mainly solves is, for the above-mentioned defect in prior art, provides a kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system.
The technical solution adopted for the present invention to solve the technical problems is: construct a kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system, comprise the lead powder storage warehouse connected successively, lead powder device for discharging, air-actuated feeding valve, sending warehouse pump, lead powder conveying gas source valve group, discharging fluidizer, storehouse pump discharging opening boost installation, pneumatic bleeder valve, ash conveying pipe pressure sensor, with the segmentation external booster of pressure sensor, ash conveying pipe, gas-solid separating device, ultrafiltration device, lead powder storehouse, nitrogen return conduits, nitrogen storage gas tank II, nitrogen reuse circulation compression system device, high pressure nitrogen pipeline, nitrogen storage gas tank I and system control device, lead powder storage warehouse is provided with level-sensing device, sending warehouse pump is provided with pneumatic blow off valve, nitrogen device processed is provided with in nitrogen recycling circulating system, nitrogen storage gas tank I and nitrogen storage gas tank II are provided with pressure sensor, nitrogen storage gas tank II is provided with nitrogen gas concn detector.
A kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system of the present invention, under lead powder storage warehouse, be provided with a set of lead powder static pressure concentrated phase segmentation assisted air-transport system, adopt static pressure concentrated phase segmentation assisted pneumatic conveying process to carry out lead powder conveying; Aforementioned lead powder static pressure concentrated phase segmentation assisted air-transport system comprises lead powder device for discharging, sending warehouse pump and is equipped with the ash conveying pipe of segmentation assisted device, adopts Nitrogen source gases to be sent to by lead powder in each production station lead powder storehouse.
A kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system of the present invention, in lead powder conveying with in nitrogen closing recycling system, be configured with nitrogen device processed, the nitrogen gas concn that can use according to close cycle, carry out automatic nitrogen to supplement, guarantee that nitrogen gas concn meets technological requirement.
A kind of lead powder nitrogen closing circulation static pressure concentrated phase segmentation assisted air-transport system of the present invention, ash conveying pipe is provided with the segmentation external booster with pressure sensor, guarantee the stable and reliable of lead powder pneumatic ash transmitting system, simultaneously also more energy-conservation.
beneficial effect of the present invention:
1, employing of the present invention will reduce Mechanical Equipment Quantity and machinery maintenance amount (great advantage that Geldart-D particle substitutes traditional mechanical transmission device is just this);
2, employing nitrogen closing of the present invention recycle, eliminate or reduces lead powder in lead-acid storage battery production process and carries the occupational hazard caused.
3, the present invention adopts static pressure concentrated phase conveying processes, on ash conveying pipe, arranges the measures such as segmentation external booster, effectively can guarantee lead powder air-transport system reliability of operation and stability, also effectively can reduce energy consumption simultaneously.

Lead powder storage warehouse is provided with a set of lead powder static pressure concentrated phase segmentation assisted air-transport system for 1 time, adopts static pressure concentrated phase segmentation assisted pneumatic conveying process to carry out lead powder conveying; Aforementioned lead powder static pressure concentrated phase segmentation assisted air-transport system comprises lead powder device for discharging 3, sending warehouse pump 6 and is equipped with the ash conveying pipe 13 of segmentation assisted device, adopts Nitrogen source gases to be sent to by lead powder in each production station lead powder storehouse 16.In lead powder conveying with in nitrogen closing recycling system, be configured with nitrogen device 22 processed, the nitrogen gas concn that can use according to close cycle, carry out automatic nitrogen and supplement, guarantee that nitrogen gas concn meets technological requirement, described conveying Nitrogen source gases pressure >=0.6MPa.
Close cycle utilization is carried out to lead powder Geldart-D particle Nitrogen source gases used: conveying lead powder nitrogen is recycled through gas-solid separating device (14), ultrafiltration device (15), nitrogen return conduits (17), nitrogen storage tank II (19), nitrogen reuse circulation compression system device (21) and nitrogen storage tank I (24) again to be carried for lead powder.According to nitrogen gas concn detector (20) determination data arranged in closed cycle system, the nitrogen device (20) processed configured in employing system at any time supplements nitrogen in nitrogen closing circulating system, guarantees that lead powder supplying nitrogen concentration meets technological requirement.
Above content is in conjunction with concrete optimal technical scheme further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
