Abstract
The utility model belongs to the technical field of a mechanization defecator device. A negative pressure collecting device for tail gas of a mechanization defecator is used for collecting tail gas of a mechanization defecator in the production of coke even gas. The negative pressure collecting device for the tail gas of the mechanization defecator comprises a mechanization defecator tail gas collecting pipe, an emergency blow off valve, a pressure regulating valve and an emergency cut-off valve. On end of the mechanization defecator tail gas collecting pipe is connected with the top air space of the mechanization defecator tail gas, and the other end of the mechanization defecator tail gas collecting pipe is connected with a negative pressure coke oven gas pipe. The pressure regulating valve and the emergency cut-off valve are arrange inside the mechanization defecator tail gas collecting pipe. An upper reach of the pressure regulating valve is provided with a tail gas emergency cut-off valve, and the emergency cut-off valve is arranged inside the tail gas emergency cut-off valve. The tail gas of the mechanization defecator is drawn to the negative pressure coke oven gas pipe at the head of the mechanization defecator, and the coke oven gas device purifying equipment is used to purify the tail gas. The negative pressure collecting device for tail gas of the mechanization defecator is reasonable in design, high in automation degree, low in operation cost, and high in efficiency. The negative pressure collecting device for tail gas of the mechanization defecator can solve the problem of the tail gas scatter of the mechanization defecator. Secondary pollution can not be created.
