Embodiment Construction

[0020] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0021] See Figure 1-Figure 4 As shown, the present invention relates to a slag discharge device for a primary cooler, including a screw conveyor 1, an upper condensate outlet 2, a baffle 3, a liquid breaker 4, a slag discharge port 5, a field sight glass 6, and a steam cleaning port 7. The slag discharge valve 8 and the remote transmission mirror 9. The liquid breaker 4 is composed of a liquid blocking part 41, an inclined part 42 and a groove part 43, wherein the liquid blocking part 41 is vertically arranged, and the inclined part 42 is connected with the liquid blocking part. 41 forms an obtuse angle, the concave part 43 and the inclined part 42 are smoothly transitioned, the bottom of the groove part 43 is a semicircular structure and welded together with the wall of the primary cooler; the liquid breaker 4 is two, along the center line of th...

Abstract

The invention relates to a slag discharge device for a primary cooler. The slag discharge device comprises a spiral conveyor, an upper-section condensate outlet, a baffle plate, a liquid cut-off disc,a slag discharge outlet, a field sight glass, a steam cleaning opening, a slag discharge valve and a teletransmission sight glass, wherein the baffle plate is arranged at the upper part of the liquidcut-off disc; the spiral conveyor is arranged in the liquid cut-off disc; an outlet end is connected with the slag discharge outlet which is connected with the slag discharge valve; the steam cleaning opening is arranged on the slag discharge outlet; and the upper-section condensate outlet, the field sight glass and the teletransmission sight glass are arranged on the wall of the primary cooler.The slag discharge device provided by the invention has the following beneficial effects: generated tar residues can be discharged in time under the condition that normal operation of the primary cooler is not affected; blockage is avoided; operation stability of a coal gas system is improved; the effects of heat exchange and naphthalene washing are improved; consumption of water is reduced; and the slag discharge device has the characteristics of simple structure and convenient operation.

Description

technical field [0001] The invention relates to a slag discharge device in the technical field of coking, in particular to a slag discharge device for a primary cooler. Background technique [0002] In the field of coking technology, the gas in the primary cooler flows down the water pipe from top to bottom, and the condensed tar mist, water mist and tar residue entrained in the gas are carried to the liquid breaker by the gas flow and discharged from the upper condensate outlet . At present, due to the shortage of coking coal resources and the requirements for anthracite coal charging in coke ovens, the fineness of coking coal blending increases, and the negative pressure of the gas collection pipeline increases, resulting in a large amount of coal powder entering the primary cooler with the raw gas, together with the precipitated naphthalene It is bonded by tar to form a sticky tar residue. The tar slag is seriously blocked at the liquid breaker, causing high resistance ...
