Background technology
Current Production by Catalytic Combustion Process in the organic waste-gas purification of various industries such as enamel-covered wire, metal printing and dyeing, chemical industry, paint all
Applied, the drying waste gas discharged particularly in the production processes such as enamel-covered wire, insulating materials, printing, because of EGT
Higher, organic concentration is higher, favourable to combustion reaction and heat recovery, and with preferable economic benefit, therefore application is very
Extensively.Catalysis combustion oxidation technology belongs to that non-flaming combustion, security are good, reaction temperature is low, auxiliary less energy consumption, dense to combustible component
Degree and calorific value limitation are few, and course of reaction does not produce NOX, with process is simple, it is energy-efficient, inflammable and explosive gas can be carried out
Treatment, is a kind of method for processing low-concentration organic exhaust gas at present.
Conventional catalytic combustion device has two kinds of heat accumulating type and heat exchange type, and heat accumulating type has combustion-supporting consumption costs few, and heat is returned
The advantage of high income, but up-front investment is big, is not suitable for little Wei enterprises.Heat exchange type uses metallic recuperator, compact conformation, volume
It is smaller and manufacturing cost is relatively low, it is widely used in little Wei enterprises.Existing heat exchange type oxidation equipment start preheating time compared with
It is long, when " cold waste gas " or " low-heat waste gas " is processed, answered because the structure limitation of " plate type heat exchanger " will consume some without effects,
Increased electricity and help hot cost.
The content of the invention
The purpose of this utility model is to provide a kind of heat exchange type catalytic oxidizing equipment, and the hot time is opened to shorten start, is carried
Height purification reaction efficiency.To achieve the above object, the utility model uses following technical scheme：
The utility model discloses heat exchange type catalytic oxidizing equipment, including device body, the connection of device body bottom side
Inlet tube, bottom opposite side connection air-introduced machine and discharge pipe；Device body inside includes upper and lower two-layer support body, on lower floor's support body
Preheating electrothermal tube, metal plate type heat exchanger are provided with, described inlet tube is connected with preheating electrothermal tube, and preheating electrothermal tube side is installed
Metal plate type heat exchanger, described metal plate type heat exchanger is provided with inlet channel, rectangular channel and outlet passageway, described rectangle
Passage is located at middle part, is formed by sheet metal closed assembly；Upper strata support body is provided with noble metal ceramic honey comb and electrothermal tube, your described gold
Category ceramic honey comb is being located at noble metal ceramic honey comb just located at the surface of metal plate type heat exchanger rectangular channel, described electrothermal tube
Top.
Preferably, described inlet tube end is provided with spark arrester.
Wherein, flame-proof switch is installed on described spark arrester.
Further, described device body top is provided with venting of dust explosion diaphragm.
As a result of above-mentioned structure, the utility model has the advantages that：The utility model inlet tube with it is pre-
Thermoelectricity heat pipe is connected, and improving temperature after making inlet exhaust gases preheated enters back into metal plate type heat exchanger, shortens preheating time, carries
Rate reaction time high.The setting of device body two-layer support body makes waste gas enter noble metal from the rectangular channel of metal plate type heat exchanger
Ceramic honey comb, then it is roundabout to rectangular channel, effectively increase the clean-up effect of waste gas.The setting of spark arrester, can prevent tempering
Accident.The setting of venting of dust explosion diaphragm, makes when the temperature and pressure in device body is exceeded, automatic-explosion, pressure of releasing, and improves dress
The security put.
