CN201921543U - Novel tail gas treating device - Google Patents

Abstract

The utility model discloses a novel tail gas treating device which comprises a heat exchanger, a tail gas recovering main pipe, a circulating water pipe, a condensate outlet and a tail gas outlet are arranged on the heat exchanger, the tail gas recovering main pipe is connected with one or more tail gas recovering branch pipes, each tail gas recovering branch pipe is connected with a tail gas generator, and the tail gas generator refers to a gas-liquid separator, a phase divider, a condensing cooler and the like that need to exhaust tail gas. Meanwhile, the condensate outlet is also connected with a condensate storage, and a tail gas outlet on the heat exchanger is connected with the tail gas recovering branch pipe(s). The novel tail gas treating device not only can effectively reduce the content of non-methane total hydrocarbon in the exhausted tail gas as well as environmental pollution and potential safety hazards, but also can recover useful components of the tail gas to reduce wastes; in addition, the novel tail gas treating device has simple structure and low cost.

Description

Novel exhaust gas processing device

Technical field

The utility model relates to harmful field of gas treatment, the recycling and processing device of harmful tail gas in especially a kind of production of ethyl.

Background technology

In the production of ethyl process, need to purify by rectifying, separate in the purification process, exhaust emissions need be carried out in many places such as gas-liquid separator, phase-splitter, condensate cooler, become the tail gas generator, owing to the volatility of the alcohol that contains in institute's discharge tail gas, ester class is stronger, very easily cause NMHC content overproof in the workshop, cause great environmental pollution and potential safety hazard.Existing solution is to install spark arrester additional, but expense is too high, so how under low-cost situation, effectively reduce the content that effluxes NMHC in the tail gas, reduced environmental pollution and potential safety hazard, the useful constituent of recovery tail gas cuts the waste and just seem very important.

The utility model content

The utility model technical assignment is at above-mentioned technical deficiency, and a kind of novel exhaust gas processing device is provided.

The technical scheme that the utility model technical solution problem is adopted is: novel exhaust gas processing device, comprise heat exchanger, described heat exchanger is provided with tail gas recycle house steward, circulating water pipe, condensate outlet and tail gas outlet, described tail gas recycle house steward links to each other with one or more tail gas recycle arms, described each tail gas recycle arm all links to each other with the tail gas generator, and described condensate outlet is connected with the condensate liquid holder simultaneously.

The outlet of tail gas on the described heat exchanger links to each other with the tail gas recycle arm, and promptly still uncooled harmful tail gas can enter the heat exchanger condensation once more from the tail gas recycle arm, until with all harmful tail gas condensation process, in order to avoid be emitted in the atmosphere contaminated environment.

The beneficial effect that the utility model can bring is:

1, effectively reduce the content that effluxes NMHC in the tail gas, reduced environmental pollution and potential safety hazard;

2, simple in structure, cost is low;

3, can also reclaim the useful constituent of tail gas, cut the waste.

Description of drawings

Fig. 1, the utility model overall structure schematic diagram.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is done following detailed description:

As shown in Figure 1, the novel exhaust gas processing device that the utility model is announced, comprise heat exchanger 1, described heat exchanger 1 is provided with tail gas recycle house steward 2, circulating water pipe 3, condensate outlet 4 and tail gas outlet 5, described tail gas recycle house steward 2 links to each other with one or more tail gas recycle arms 6, described each tail gas recycle arm 6 all links to each other with tail gas generator 7, and said here tail gas generator 7 is meant that many places such as gas-liquid separator, phase-splitter and condensate cooler need carry out the equipment of exhaust emissions.Described condensate outlet 4 places also are connected with condensate liquid holder 8 simultaneously.

Tail gas on the described heat exchanger 1 outlet 5 links to each other with tail gas recycle arm 6, promptly still uncooled harmful tail gas can export 5 miscarriages from tail gas, enters heat exchanger 1 condensation once more through tail gas recycle arm 6, until with all harmful tail gas condensation process, in order to avoid be emitted in the atmosphere contaminated environment.

In sum, the utility model can effectively reduce the content that effluxes NMHC in the tail gas, reduce environmental pollution and potential safety hazard; Can also reclaim the useful constituent of tail gas, cut the waste; And simple in structure, cost is low.

Claims (2)

1. novel exhaust gas processing device, it is characterized in that: comprise heat exchanger, described heat exchanger is provided with tail gas recycle house steward, circulating water pipe, condensate outlet and tail gas outlet, described tail gas recycle house steward links to each other with one or more tail gas recycle arms, described each tail gas recycle arm all links to each other with the tail gas generator, and described condensate outlet is connected with the condensate liquid holder simultaneously.

2. novel exhaust gas processing device according to claim 1 is characterized in that: the tail gas outlet on the described heat exchanger links to each other with the tail gas recycle arm.
