Abstract
The invention relates to an access door which is installed on an evaporative cooler of a converter coal gas dry-process dedusting system. The access door comprises an inner layer door and an outer layer door, wherein the inner layer door is installed on the inner wall of the evaporative cooler; the outer layer door is installed on the outer wall of the evaporative cooler; the middle part of one side of the inner layer door adjacent to the outer layer door is provided with a long grip; the long grip is connected with a spring; and the other end of the spring is fixed to the center of the outer layer door. The inner layer door of the access door is utilized to overcome the defects in the inner wall of the evaporative cooler, thereby preventing dust from hardening and generating large scale deposit, and ensuring the safety of the evaporative cooler.
Description
Technical field
The present invention, about a kind of access door, refers to a kind of access door for converter gas dry-dedusting system evaporative cooler especially.
Background technology
Converter gas dry method electrostatic precipitation technology is state-of-the-art coal gas dust removal of converter technology, it mainly contains the compositions such as gasification cooling flue, evaporative cooler, electrostatic precipitator, blower fan, switching valve, gas cooler and diffusing chimney, wherein evaporative cooler makes coal gas drop to 200 ℃ of left and right by spraying into appropriate water in the raw gas to 800-1000 ℃, realizes the thick dedusting of coal gas of converter simultaneously.Because evaporative cooler inside is that complicated gas-liquid-solid three-phase flows, easily at evaporative cooler wall, form fouling.Existing evaporative cooler has 16 access doors, access door has destroyed the continuity of evaporative cooler internal cylinder, thereby more easily at access door place, form large fouling, fouling has not only affected the proper flow in evaporative cooler, and coming off of large fouling also constitutes a threat to the device of evaporative cooler bottom.
Summary of the invention
In view of this, main purpose of the present invention is to provide a kind of access door for converter gas dry-dedusting system wet cooling tower that can make evaporative cooler use and prevent fouling safely.
For achieving the above object, the invention provides a kind of access door, it is installed on the evaporative cooler of converter gas dry-dedusting system, described access door includes inner layer door and outer door, this inner layer door is installed on the inwall of evaporative cooler, and this skin door is installed on the outer wall of evaporative cooler, and this inner layer door is provided with a long handle near the middle part of a side of outer door, this long handle is connected with a spring, and this spring the other end is fixed on this skin door center.
The long handle of described inner layer door is provided with two supports.
Described outer door is provided with access door handle.
Between described outer door and the outer wall of described evaporative cooler, be provided with sealing-ring.
Described outer door edge is fixed by bolt and described evaporative cooler.
Access door of the present invention has been repaired the defect of evaporative cooler inwall by inner layer door, thereby has avoided dust harden and generate large fouling at this, and has guaranteed the safety of evaporative cooler.
Accompanying drawing explanation
Fig. 1 is the structural representation of access door in the present invention;
Fig. 2 is the schematic surface of the outer door in the present invention;
Fig. 3 is the sectional view along A-A line in Fig. 1.
Embodiment
For ease of the effect of structure of the present invention and realization is had to further understanding, the existing preferred embodiment that develops simultaneously is by reference to the accompanying drawings described in detail as follows.
As shown in Figure 1 to Figure 3, access door of the present invention includes inner layer door 2 and outer door 3, this inner layer door 2 is installed on the inwall of evaporative cooler 1, and be of similar shape and radian with evaporative cooler 1 inwall, to reach the object of repairing evaporative cooler 1 inwall, outer door 3 is installed on the outer wall of evaporative cooler 1, and inner layer door 2 is provided with a long handle 20 near the middle part of a side of outer door 3, this long handle 20 is connected with a spring 21, and these spring 21 the other ends are fixed on outer door 3 centers.The long handle 20 of inner layer door 2 is provided with two supports 22, and after assurance is put into access opening by inner layer door 2, it can keep normal position.This skin door 3 is provided with access door handle 30, between outer door 3 and evaporative cooler 1 outer wall, be provided with sealing-ring 4, outer door 3 edges are fixing with evaporative cooler 1 by bolt 31, thereby and holddown spring 21 and sealing-ring 4 are realized the sealing function of access door simultaneously by bolt 31.
Access door of the present invention has been repaired the defect of evaporative cooler inwall by inner layer door, thereby has avoided dust harden and generate large fouling at this, and has guaranteed the safety of evaporative cooler.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
