Abstract
A wear flue device that is used for pneumatic dust removal device's ash falling pipe. The inlet flue and the outlet flue are too close to each other, so that the bottom space of the inlet flue is insufficient, and a pneumatic ash removal system cannot be arranged. The invention comprises the following components: the pneumatic dust removing device comprises an inlet flue (4) and an outlet flue (6), wherein threaded holes are formed in an upper inner guard plate (7) and a lower inner guard plate (7) of the outlet flue, enamel-plated pipes (2) with threads at two ends are arranged in the outlet flue in a penetrating mode, the enamel-plated pipes with the threads at two ends are connected with threaded holes in the upper end of the outlet flue in a threaded mode and then penetrate out of the outer side of the outlet flue to be connected with an upper fastening sealing nut (1), the enamel-plated pipes with the threads at two ends are connected with threaded holes in the lower end of the outlet flue in a threaded mode and then penetrate out of the outer side of the outlet flue to be connected with a lower fastening sealing nut (3), and a dust falling pipe (5) of a pneumatic. The invention relates to a flue-passing device of an ash falling pipe of a pneumatic ash removing device.
Description
The technical field is as follows:
the invention relates to a flue-passing device of an ash falling pipe for a pneumatic ash removing device.
Background art:
when SCR denitration transformation is carried out on an existing thermal power boiler, an ash hopper is required to be arranged when an inlet flue is frequently encountered, the inlet flue and an outlet flue are too close to each other, the condition that the bottom space of the inlet flue is not enough is caused, and a pneumatic ash removal system cannot be arranged.
The invention content is as follows:
the invention aims to solve the problem that the bottom space of an inlet flue is insufficient due to the fact that an ash hopper needs to be arranged in the inlet flue at present and the inlet flue and the outlet flue are too close to each other, and provides a flue passing device of an ash falling pipe for a pneumatic ash removing device, wherein the ash falling pipe can pass through an SCR (selective catalytic reduction) outlet flue, and the arrangement space of a pneumatic ash removing system is expanded.
The above purpose is realized by the following technical scheme:
a flue-passing device for an ash falling pipe of a pneumatic ash removing device comprises: the pneumatic dust removing device comprises an inlet flue and an outlet flue, wherein threaded holes are formed in an upper inner guard plate and a lower inner guard plate of the outlet flue, enamel-plated pipes with threads at two ends are arranged in the outlet flue in a penetrating mode, the enamel-plated pipes with threads at two ends are in threaded connection with threaded holes in the upper end of the outlet flue and penetrate out of the outer side of the outlet flue to be connected with an upper fastening sealing nut, the enamel-plated pipes with threads at two ends are in threaded connection with threaded holes in the lower end of the outlet flue and penetrate out of the outer side of the outlet flue to be connected with a lower fastening sealing nut, and a dust falling pipe of a pneumatic dust removing system arranged on the inlet flue penetrates through the enamel-plated pipes with threads at two ends.
The diameter of the threaded hole at the upper end of the outlet flue is larger than that of the threaded hole at the lower end of the outlet flue.
The diameter of the upper end of the enamel-plated pipe with threads at two ends is larger than that of the lower end of the enamel-plated pipe.
Has the advantages that:
1. the invention enables the ash falling pipe to pass through the SCR outlet flue, expands the arrangement space of the pneumatic ash removal system and solves the problem that the pneumatic ash removal can not be arranged due to space limitation.
2. The invention adopts a sleeve structure, and solves the problem that the direct welding of the ash falling pipe and the flue can cause tension cracking. The wear-resisting characteristic of the pipe is improved by enameling the pipe penetrating the flue, and the detachable sleeve structure is more convenient to overhaul and replace.

The specific implementation mode is as follows:
example 1:
a flue-passing device for an ash falling pipe of a pneumatic ash removing device comprises: the pneumatic dust removing device comprises an inlet flue 4 and an outlet flue 6, wherein threaded holes are formed in an upper inner guard plate 7 and a lower inner guard plate 7 of the outlet flue, enamel-plated pipes 2 with threads at two ends are arranged in the outlet flue in a penetrating mode, the enamel-plated pipes with threads at two ends are in threaded connection with threaded holes in the upper end of the outlet flue and penetrate out of the outer side of the outlet flue to be connected with an upper fastening sealing nut 1, the enamel-plated pipes with threads at two ends are in threaded connection with threaded holes in the lower end of the outlet flue and penetrate out of the outer side of the outlet flue to be connected with a lower fastening sealing nut 3, and a dust falling pipe 5 of a pneumatic dust removing system 8 arranged on the inlet flue penetrates through the enamel-plated pipes with threads at two ends.
Example 2:
according to the flue penetrating device of the ash falling pipe of the pneumatic ash removing device in the embodiment 1, the diameter of the threaded hole at the upper end of the outlet flue is larger than that of the threaded hole at the lower end of the outlet flue.
Example 3:
according to the flue-through device of the ash falling pipe of the pneumatic ash removing device in the embodiment 2, the diameter of the upper end of the enamel-plated pipe with the two threaded ends is larger than that of the lower end of the enamel-plated pipe.
