Problems solved by technology

[0003] However, due to the trains passing through the railway coal delivery station, both ends of the coal yard cannot be closed. As a result, a large amount of coal dust overflows from the entrance and exit when the train enters and exits, which does not meet the environmental protection requirements.

Embodiment Construction

[0021] A railway coal delivery station has a freight yard with a length of 2 kilometers and a fully enclosed coal bunker. However, because the coal is shipped by train, the entrance and exit of the trains at both ends of the coal bunker cannot be closed, and they are directly opened, causing coal dust to spill out of the bunker. A device to prevent coal dust from spilling is installed above the entrance and exit of the train at both ends of the coal bunker. It is sprayed from top to bottom to form a water curtain, which effectively prevents the overflow of coal dust in the bunker and does not affect the vehicles entering and leaving the bunker. The dust prevention effect is good. .

[0022] The nozzles are arranged at the upper part of the inlet and outlet of the coal bunker, and are arranged at a certain interval along the upper part of the inlet and outlet of the coal bunker. The nozzle is installed with a solenoid valve; the nozzle is connected to the water outlet pipe, an...

Abstract

The invention discloses a device arranged at a fully sealed coal cabin access for preventing coal dust from outwards flowing. The device is arranged at the upper part of the fully sealed coal cabin access. The device comprises a water pump, a water conveying pipe, a spray nozzle, electric equipment and a control system. The device sprays water mist from top to bottom to form a water curtain; the outward flowing of coal dust in the cabin can be effectively prevented; no influence is caused on access of vehicles into or out from the coal cabin.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a device for preventing coal dust from overflowing at the entrance and exit of a fully enclosed coal bunker. Background technique [0002] Due to strong winds and serious dust pollution during operation and storage, the railway coal delivery station has been listed as a deadline for treatment by the environmental protection department and requires full closure measures, otherwise it will face the risk of suspension of production and shutdown. [0003] However, due to the trains passing through the railway coal delivery station, both ends of the coal yard cannot be closed. As a result, a large amount of coal dust overflows from the entrance and exit when the train enters and exits, which fails to meet environmental protection requirements. Contents of the invention [0004] The object of the present invention is to provide a simple, economical and practical de...
